	* doc/texinfo.tex (\mtadjustprotcode): Use new count \countC
	instead of reusing \countB which appears to clash with \pdfgettoks,

            Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (@documentencoding): Mention possibility

2022-10-25  Patrice Dumas  <pertusus@free.fr>

	* tp/maintain/copy_change_file_name_encoding.pl: change the character
	appearing in the test of 8bit encoded include file, as it may be
	special on Windows.  Report from Gavin.

2022-10-25  Patrice Dumas  <pertusus@free.fr>

	* tp/maintain/copy_change_file_name_encoding.pl: use a character

2022-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl (filter_tree_keys): Do not output 'parent'

2022-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (@minus): Do not state that '-' always produces

2022-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Makefile.am (distlean-local, CLEANFILES, DISTCLEANFILES):
	Remove references to blib, pm_to_blib and Makefile.old files

	file, not present anywhere.

2022-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* Makefile.am, README, README-hacking: Do not distribute the
	contrib/ subdirectory.  This shrinks the .tar.xz file to
	5.2 MB.

2022-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* js/Makefile.am (EXTRA_DIST): Do not distribute 'examples'

	the t/index-search.sh test.

2022-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* README-hacking: advice on valgrind

2022-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (@minus): Do not state that '-' produces

	formats.  Report from Vincent Lefèvre.

2022-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	awk check

	* configure.ac: Rewrite awk check to use
	AC_PATH_PROGS_FEATURE_CHECK.  Check for user-defined functions.

	program names.

2022-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi: Limit references to the XML output, as
	it is not likely to be useful.  Eliminate references to
	"TexinfoXML" or "Texinfo-XML".
	(Overview): Do not mention PostScript format.  Mention EPUB 3 and
	LaTeX.  Do not say that using Emacs is "especially convenient".
	(Output Formats) <XML>: Edit.  Make it more prominent that the XML
	format is not usable.

2022-10-25  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Translations.pm (gdt): replace argument variable name
	$context with $replaced_substrings, as it could be confused with
	message context.

2022-10-25  Patrice Dumas  <pertusus@free.fr>

	* po/Makevars (XGETTEXT_OPTIONS): add -k__p:1c,2 for __p() in perl.

2022-10-24  Patrice Dumas  <pertusus@free.fr>

	Fix/add @direntry for texi2any_api and texi2any_internals

	* doc/texi2any_api.texi, doc/tp_api/Makefile.am (EXTRA_DIST),
	texi2any_internals_preamble.texi: fix the texi2any_api @direntry
	to refer to texi2any_api.
	Add a @dircategory/@direntry to texi2any_internals by putting the
	preamble in texi2any_internals_preamble.texi and setting the
	preamble argument of pod2texi.
	Report from Andreas Schwab.

2022-10-24  Patrice Dumas  <pertusus@free.fr>

	* Pod-Simple-Texinfo/pod2texi.pl, doc/tp_api/Makefile.am:
	no @setfilename output if --setfilename is not given in argument
	of pod2texi.pl.
	Remove --setfilename from the rule generating texi2any_internals.texi.

2022-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/HTML.pm (_convert_menu_entry_type):
	Initialize a variable.

	This avoids error "Use of uninitialized value $href in string ne..."
	when running the test suite.

2022-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Cross Reference Parts, Marking Text, @set @value)

	* configure.ac (TI_AWK): Reorder to check for awk after gawk.

2022-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Conditional Nesting): Edit.  Do not
	vaguely describe the subject as "tricky".  Ignore some
	text.

2022-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Reporting Bugs): Mention 'git diff'.  Do
	not encourage sending large input files in bug reports.
	(Output Formats): Remove useless word "brief".
	(@enumerate): Remove "brief" and some self-referential text.
	(@set @clear @value): Edit and shorten.
	(HTML CSS): Edit.  Remove @ignore'd text.

2022-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

2022-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* README-hacking: Add agendum for next release
	* README: Revise - https for URL's, mention LaTeX and EPUB 3 output,
	info.texi not part of Texinfo distribution, prefer "texi2any" to
	"makeinfo".

2022-10-23  Patrice Dumas  <pertusus@free.fr>

	* Pod-Simple-Texinfo/prove.sh: remove -w from prove arguments for old

2022-10-23  Patrice Dumas  <pertusus@free.fr>

	* tp/tests/run_parser_all.sh (check_need_command_line_unicode),
	tp/tests/many_input_files/*non_ascii*.sh: skip tests needing
	UTF-8 encoded non-ASCII characters on the command line on Windows,
	as the shell may interpret those characters to be encoded in the
	current user codeset and pass them incorrectly to the programs.
	Report from Eli Zaretskii.

2022-10-23  Patrice Dumas  <pertusus@free.fr>

	* tp/tests/run_parser_all.sh,
	tp/maintain/copy_change_file_name_encoding.pl: consider that
	recoding of file name to Latin1 as needed by some tests is not
	reliable on Windows, as the non-ASCII character may be stored
	in the filesystem as an Unicode point using the current codepage
	to convert, and not the Latin1 encoding expected from the Perl code.
	Add comments to explain that.  Report from Eli Zaretskii.

2022-10-23  Patrice Dumas  <pertusus@free.fr>

	* configure.ac (HOST_IS_WINDOWS_VARIABLE), tp/defs.in: add variable
	set to yes if host is Windows.

2022-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* configure.ac (TI_AWK): Check for "nawk" before awk, as
	plain awk on Solaris 11.4 is an archaic version lacking features
	we need, like user-defined functions.  Report from Bruno Haible.

2022-10-23  Bruno Haible  <bruno@clisp.org>

	Fix install-info tests on mingw

	 * install-info/tests/defs.in [mingw]: Set diff to
	'diff --strip-trailing-cr'.
	 * install-info/tests: Use ${diff} in all tests.

2022-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Avoid calling Perl version of 'free'

	* tp/Texinfo/XS/parsetexi/api.c (reset_parser):
	Do not call 'free' - do everything via functions in other files.

	* tp/Texinfo/XS/parsetexi/api.c
	(set_input_file_name_encoding, conf_set_input_file_name_encoding)
	(set_locale_encoding, conf_set_locale_encoding)
	(set_documentlanguage_override, conf_set_documentlanguage_override):
	Provide wrappers with names starting with 'conf_', and move the
	implementations to other files.

	* tp/Texinfo/XS/parsetexi/input.c
	(set_input_file_name_encoding, set_locale_encoding): Add.  Allow
	null arguments.
	* tp/Texinfo/XS/parsetexi/parser.c
	(set_documentlanguage_override): Add.  Allow null argument.
	(set_documentlanguage):  Allow null argument.

	Report from Eli, who got "Free to wrong pool" error.

2022-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* install-info/tests/README: Complete list of tests (not
	updated since 2014).
	* install-info/tests/ii-0054-test: Remove commented-out code.
	* install-info/tests/ii-0056-test: Correct test number and update
	reference results.

2022-10-23  Patrice Dumas  <pertusus@free.fr>

	* tp/ext/epub3.pm (epub_setup): use / as file separator for
	INFO_JS_DIR, which is used both for HTML paths, requiring / and
	paths to files on the filesystem, for which / may not be native,
	but works for Unix and Windows paths.  Report from Eli Zaretskii.

2022-10-23  Patrice Dumas  <pertusus@free.fr>

	Avoid UTF-8 encoded file name in make rule prerequisite

	* tp/maintain/copy_change_file_name_encoding.pl, tp/tests/Makefile.am:
	convert to latin1 from plain ASCII filename, substituting accented
	letters in tp/maintain/copy_change_file_name_encoding.pl.  Report from
	Eli Zaretskii.

2022-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/where-dir-file.sh: Remove $ from argument to grep,
	as this causes problems on mingw-w64 where ginfo outputs
	lines with CRLF line endings but the grep program does not
	handle them specially.  Report from Bruno Haible.

2022-10-23  Eli Zaretskii  <eliz@gnu.org>, and
            Gavin Smith    <gavinsmith0123@gmail.com>

	* tp/texi2any.pl [MS-Windows]: If loading I18N::Langinfo doesn't
	work, then get codepage with GetACP() using Win32::API module.

2022-10-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/XSParagraph.xs,
	* tp/Texinfo/XS/parsetexi/api.c
	[defined _WIN32 && !defined __CYGWIN__]:
	'#undef free' after including "perl.h" (which includes stdlib.h
	from Gnulib) and before including "XSUB.h" to avoid warnings
	about redefining symbols in Perl headers that Gnulib already
	redefined.  From Eli.

2022-10-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/configure.ac: Attempt to disable gnulib
	definitions for fdopen, mktemp and putenv on MS-Windows by
	setting variables with GL_GNULIB_MDA_ prefixes.

2022-10-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Minimum): Minor grammar fix.

2022-10-22  Patrice Dumas  <pertusus@free.fr>

2022-10-22  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/ParserNonXS.pm, tp/Texinfo/XS/parsetexi/command_data.txt,
	tp/Texinfo/XS/parsetexi/parser.c (check_valid_nesting): set @*heading
	heading customization variables as contain_simple_text.  Modify perl
	Parser to handle in_heading_spec_commands similarly as XS parser.

	tp/Texinfo/XS/parsetexi/parser.c (check_valid_nesting): add explicit
	contain_plain_text and contain_simple_text flags to all commands
	instead of using conditionals.  Use contain_plain_text instead of
	contain_simple_text for LINE_text and LINE_specific.

2022-10-21  Gavin Smith  <gavinsmith0123@gmail.com>

	Save and restore LC_MESSAGES

	* tp/Texinfo/Translations.pm (gdt):
	Save and restore LC_MESSAGES rather than LC_ALL, as this seems
	safer than switching LC_ALL and not switching it back (see change
	on 2022-10-20).  Don't do this on MS-Windows where there were
	problems before with LC_MESSAGES (see change on 2021-02-27).

2022-10-21  Patrice Dumas  <pertusus@free.fr>

	* doc/refcard/txicmdcheck (read_refidx): filter out @sortas.

	with the evolution of the language and the Texinfo manual and other
	output formats than TeX and Info.

2022-10-20  Patrice Dumas  <pertusus@free.fr>

	Add @subentry, @seealso, @seeentry and @thissection* to refcard

	* doc/refcard/txirefcard.tex (Indices, Page headers and footers):
	add information on @subentry, @seealso, @seeentry and @thissection*.

2022-10-20  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi (Predefined Indices): add findex entries for
	index entry commands based on two letter index names, such as
	@cpindex.  Add a sentence to explain that index entry commands
	based on two letter index names are valid.

2022-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Command List): Add @thissection,
	@thissectionname, @thissectionnum.  From Patrice.

2022-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/refcard/txicmdcheck (read_tp):

2022-10-20  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi (Debugging with @TeX{}): remove obsolete @refill in
	example.

2022-10-20  Patrice Dumas  <pertusus@free.fr>

	* doc/refcard/txicmdcheck: minor, use directly hashes in some cases.

2022-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	Do not restore LC_ALL

	* tp/Texinfo/Translations.pm (gdt):
	Do not restore LC_ALL as this appears to override LC_CTYPE, at
	least on DragonFlyBSD 5.9, and LC_CTYPE needs to be set correctly for
	correct iteration over UTF-8 strings by mbrtowc in the XS paragraph
	formatting module.

	* doc/Makefile.am (Texinfo/Commands.pm): Add $(srcdir) to rule.

2022-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	util/txicustomvars: compare manual and lists from code and output

	add missing customization variables for @-commands.

2022-10-19  Patrice Dumas  <pertusus@free.fr>

	More efficient subnode dumping

	* info/session.c (dump_node_to_stream): Take a FILE_BUFFER *
	argument rather than a filename.  Only get nodes from this file
	buffer, using info_get_node_of_file_buffer.  This avoids looking
	for the file for every node when dumping subnodes.
	(dump_nodes_to_file): Call info_find_file before calling
	dump_node_to_stream.

	* doc/texinfo.texi (@node Raise/lower sections): constraint
	on menu only if not automatic menus.

	* doc/texinfo.texi (@code{@@cartouche}): use 'Highlighting Blocks'

	* doc/texinfo.texi (Inserting Math): ref to tex4ht customization,
	\mathopsup not in LaTeX.

	* doc/texinfo.texi (Raw Formatter Commands): the description of other
	raw formats in Texinfo XML is incorrect, put it in an @ignore block.

	of get_manpage_node.

2022-10-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/info.c (main) <--output>: Exit with status of 1, not 0,

	Use explicit \mathit for slates @-commands in math

	* tp/Texinfo/Convert/LaTeX.pm: for slanted indicatric commands,
	such as @var in math use \mathit instead of no command, as
	the space between the letters in argument can be important for some
	letters (such as ff), corresponding to letters being multiplied
	rather than to words, which is a better interpretation for
	@-command arguments.  Report from Vincent Lefèvre.

	Add _accent_entities_html_accent() and
	_accent_entities_numeric_entities_accent() functions in

	(set_tree_unit_file, set_file_path, _set_tree_units_files),
	tp/Texinfo/Convert/HTML.pm (_html_set_pages_files): split set_file_path
	out of set_tree_unit_file to set file path for each file name,
	which should be done for each file name, and therefore with a

	of kbd in example, it does not depend on being in @code or not,
	only of being in @example or not and the condition is kbd as
	code outside of @example, not inside.

	In @r do not consider @kbd to be in code

	* tp/Texinfo/ParserNonXS.pm (_kbd_formatted_as_code),
	tp/Texinfo/XS/parsetexi/parser.c (kbd_formatted_as_code):
	if in a style_no_code brace commands, consider that kbd is not in
	code.  Use the same code in ParserNonXS as in the XS parser.

2022-08-23  Patrice Dumas  <pertusus@free.fr>

	Classify style brace commands as code/no_code/other directly

	* tp/Texinfo/Common.pm (%brace_commands), tp/Texinfo/ParserNonXS.pm

	No separate node for PDF output from DVI output

	* doc/texinfo.texi
	(Format with @command{texi2dvi} or @command{texi2pdf}):
	rename 'Format with @command{texi2dvi}' as
	'Format with @command{texi2dvi} or @command{texi2pdf}'
	as it is what the node is about.
	remove the 'PDF Output' node, add it as an @anchor{} in
	'Format with @command{texi2dvi} or @command{texi2pdf}'
	instead, since all the relevant information in 'PDF Output'
	is already in 'Format with @command{texi2dvi}' and there is
	additional information.
	'Format with @command{texi2dvi}' can still be used when
	referring only to texi2dvi.
	Fix places were texi2dvi was used instead of texi2pdf.

	(Format with @command{tex}/@command{texindex}): add a sentence
	information on doing pdf formerly in 'PDF Output'.

	from context where @heading is pathological, as it should not be
	particularly problematic.

2022-08-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\need):
	End with a \penalty0 so that \safewhatsit and \dobreak do

	encodings with non-ASCII characters in node names fail in
	the '@code{@@documentencoding}' node.  Remove uneeded information

	be portable.
	(@code{@@euro}): remove information on the 8bit encoding since
	they should not be used anymore.

	(Internationalization of Document Strings): remove @ from
	documentlanguage and documentencoding, these are not @-commands

	a FIXME in comment to remove the constraint on extra space in
	Info as both the standalone and Emacs Info reader handle multiple
	spaces right now.

	* doc/texinfo.texi (HTML Xref Node Name Expansion): newlines in
	node names are correctly handled in all the output formats, remove
	the parenthesis stating that it is not the case.

	* doc/texinfo.texi (Info Format Menu): add a precision that in menu
	there is * instead of * (N|n)ote in cross-references.

2022-08-18  Gavin Smith  <gavinsmith0123@gmail.com>

	@need

	* doc/texinfo.tex (\need): Implement with vertical skips
	and penalties only, not with \vtop or \kern.  This has more
	reliable results when followed by a section title.  It also
	may work better with footnotes.  Reports from Werner Lemberg.

2022-08-18  Patrice Dumas  <pertusus@free.fr>

	Consider non ascii spaces to be characters for node name normalization

	* tp/Texinfo/Convert/NodeNameNormalization.pm (_unicode_to_protected)

	all have display width 1.  Faulty line breaking for DEL characters
	reported by Patrice.

2022-08-18  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/plaintext_tests.t (del_quote_linebreaking):
	New test to track line breaking with DEL-quoting.

	Fix LaTeX chapter page breaks

	* tp/Texinfo/Convert/LaTeX.pm (_latex_header)
	<\GNUTexinfonopagebreakheading>:
	Wrap redefinitions in a group; otherwise, \clearpage etc.
	would be disabled for the rest of the document, leading to
	bad page breaks and excess vertical whitespace near chapter
	headings.

2022-08-17  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/scan.c (scan_reference_target) <menu entry>:
	Canonicalize whitespace in node name to avoid anomaly where texi2any
	would not warn about menu entry even though it didn't work.
	From Patrice.

2022-08-17  Patrice Dumas  <pertusus@free.fr>

	Transform @* to spaces in node and menu lines in Info

	* tp/Texinfo/Convert/Plaintext.pm (new_formatter)
	(process_printindex, _convert): add 'no_added_eol' as
	formatter status to have @* transformed to space instead

2022-08-17  Gavin Smith  <gavinsmith0123@gmail.com>

	Recommendations on markup on @def* lines

	* doc/texinfo.texi (Marking Definition Arguments):
	Do not make its own node, including in previous node
	"Def Cmd Conventions".  Integrate with discussion of
	&keywords.  Mention the possibility of using a @macro
	but do not include any examples.  Do not promise what
	@slanted nested in @code does.

2022-08-17  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi: url -> URL throughout.

2022-08-17  Gavin Smith  <gavinsmith0123@gmail.com>

	(Xref Link Basics): avoid naming specific formats when not needed
	or incorrect.  Use specific format when needed.

	@*ref with a fourth argument and no fifth argument.  Remove the
	sentence stating that the converse of @inforef is @cite as it is
	not exact, @cite would be the converse of @inforef with the third
	argument only.

	node names in the text in 'Node Line Requirements'.
	Update texts referring to constraints in node names to refer to
	that anchor for all the information on that subject.

	(Info Format Regular Nodes): do not refer to @@-commands, it is
	confusing in the context of the Info format.

	(Info Format Printindex): refer to the menu and not to the node.


2022-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Info Format Cross Reference):

2022-08-16  Patrice Dumas  <pertusus@free.fr>

	Protect node names with comma in node pointers

	* tp/Texinfo/Convert/Info.pm (format_node): protect node names
	with comma in node pointers, and warn about node name containing
	a comma only for external nodes, internal nodes should have been

2022-08-16  Patrice Dumas  <pertusus@free.fr>

	Quote problematic node names in Info in the default case

	* NEWS, doc/texinfo.texi (Node Line Requirements),
	tp/Texinfo/Convert/Info.pm (%defaults),
	doc/tp_api/Makefile.am (AM_MAKEINFOFLAGS): set INFO_SPECIAL_CHARS_QUOTE
	in the default case in Info to quote problematic node names.  In the Emacs
	Info reader and in old readers, DEL character will appear, but the node

	them marked that way.

2022-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Cross Reference Parts): Remove examples
	to make the cross-reference parts more visible in this node.

	Info output for reference commands

	* tp/Texinfo/Convert/Plaintext.pm (_convert) <ref commands>:
	Combine code handling an xref with a separate label with code
	where the node name is the label.  Both blocks of code were
	very similar apart from different requirements for DEL-quoting.
	Check for following punctuation slightly differently
	and integrate better with DEL-quoting mechanism.

2022-08-15  Patrice Dumas  <pertusus@free.fr>

	Give recommendations on markup on @def* lines

	* doc/texinfo.texi (Marking Definition Arguments): explain why

	Protect node in index entry if INFO_SPECIAL_CHARS_QUOTE is set

	* tp/Texinfo/Convert/Plaintext.pm (process_printindex): protect
	node name in index if INFO_SPECIAL_CHARS_QUOTE is set.  Protect
	characters that need to be protected in menu node entry after

2022-08-15  Patrice Dumas  <pertusus@free.fr>

	Set INFO_SPECIAL_CHARS_WARNING in Info to 1

	* doc/texinfo.texi (Other Customization Variables),

	names without extra clarificatory text.  Output these for
	Info and HTML output.  Remove other clarifications where the
	command name is longer than a byte.

	This makes it easier to look up documentation of these
	commands in Info.  For example, "info texinfo r" would not
	go to the documentation of @r, because the index entry didn't
	match exactly: it was "r (roman font)", not "r".

2022-08-01  Patrice Dumas  <pertusus@free.fr>

	not add to @INC directories that are only needed when installed.
	use pkgdatadir for js $jssrcdir.

	* tp/texi2any.pl: changes in spacing.

2022-07-29  Patrice Dumas  <pertusus@free.fr>

	Document that &word should be marked explicitly on @def* lines

	* doc/texinfo.texi (Def Cmd Conventions, Sample Function Definition):
	document that &word should be marked explicitly on the @def*
	line if it is to be strongly emphasized.  It is only done
	automatically in TeX and this feature will be removed in the future.

2022-07-29  Patrice Dumas  <pertusus@free.fr>

	Only @r stops upright. Propagate upright in non slanted

	* tp/Texinfo/Convert/LaTeX.pm (%need_known_embrac, _convert):
	embrac is not propagated to \texttt and similar non slanted
	command.  We want to propagate, so use \EmbracMakeKnown{}.
	We do it locally because \textt redefinition, for example
	breaks \hyperref.  To do it more than once, we need to undefine
	symbols set by \EmbracMakeKnown{}.

2022-07-29  Gavin Smith  <gavinsmith0123@gmail.com>

	@r and @t in def line

	* doc/texinfo.tex (\r, \t): Cancel special definitions made
	for ( ) [ ] & on def line.
	* doc/texinfo-tex-test.texi (Definitions): Add example.

2022-07-29  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/LaTeX.pm (_convert): when ignoring
	Top node, generate @float and @anchor \label if in a
	paragraph in main document (or in a float).

2022-07-29  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/LaTeX.pm (_convert): when ignoring
	Top node, generate @float and @anchor \label if directly
	in main document.

2022-07-29  Patrice Dumas  <pertusus@free.fr>

	Fix NO_TOP_NODE_OUTPUT and title page formatting reference

	* tp/Texinfo/Convert/HTML.pm (register_footnote)
	(_convert_printindex_command): really skip footnotes and
	index entries in Top node when NO_TOP_NODE_OUTPUT is set.

	* tp/Texinfo/Convert/HTML.pm (_convert_printindex_command):
	do not output letters that have no index entries associated.

	* tp/Texinfo/Convert/HTML.pm (_default_format_title_titlepage):
	(%available_converter_info, output, convert): replace
	_print_title by format_title_titlepage formatting reference.
	Call format_title_titlepage after setting the
	current_filename, but before starting to format the document.  The
	title based on @titlepage or simpletitle formatted by
	format_title_titlepage is a new global info 'title_titlepage'.

2022-07-29  Gavin Smith  <gavinsmith0123@gmail.com>

	More isolation for @r

	* doc/texinfo.tex (\r):
	Cancel special definition of & used on def line.
	* doc/texinfo-tex-test.texi (Definitions): Add example.

	Patrice reported that input like @r{@b{&rest}} led to an error
	"Argument of & has an extra }", which was due to the need for a
	space to delimit the argument of &.

2022-07-28  Patrice Dumas  <pertusus@free.fr>

	LaTeX @deftype* not in slanted, only in code

	* tp/Texinfo/Convert/LaTeX.pm (%deftype_commands, _convert):
	put @deftype* command names in %deftype_commands.  Do not consider
	@deftype* arguments to be metasyntactic variables in code, but only
	code.

2022-07-28  Patrice Dumas  <pertusus@free.fr>

	LaTeX @def* in code, upright brackets and parentheses

	* tp/Texinfo/Convert/LaTeX.pm (_protect_text): do not protect
	brackets.  It is needed for embrac package to work, but it
	is also useless to protect brackets as we already protect \
	such that there cannot be a situation where [ ] can be interpreted
	as macro optional argument.
	* tp/Texinfo/Convert/LaTeX.pm (_latex_header, _stop_embrac)
	(_restart_embrac_if_needed, _convert): use the embrac package
	to format upright parentheses and brackets on @def* line.  Turn
	off embrac when opening a style commands.
	remove _only_slanted_no_code_contents and associated types.

2022-07-28  Patrice Dumas  <pertusus@free.fr>

	Have @r isolate formatting from surrounding text for fonts

	* tp/Texinfo/Convert/LaTeX.pm (%LaTeX_style_brace_commands),
	tp/Texinfo/Convert/HTML.pm (%css_element_class_styles):
	use \textnormal for @r in LaTeX, and add font-style: normal
	to @r CSS style in HTML.  This allows isolating @r argument
	formatting from surrounding text formatting.

2022-07-27  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/LaTeX.pm (_latex_header, _convert): protect
	only the most problematic characters in image file name.  Use
	\detokenize in argument of \fbox to be sure that the non escaped
	characters in image file name have no special meaning, when TEST
	is set.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	@set txidefnamenospace in LaTeX

	* tp/Texinfo/Convert/LaTeX.pm (_convert) <@def*>:
	Correct check for whether txidefnamenospace was in effect for
	block.

2022-07-27  Patrice Dumas  <pertusus@free.fr>

	Text for contents for @*ref in section title in LaTeX

	* tp/Texinfo/Convert/LaTeX.pm (_convert): if in a section heading
	formatting use \texorpdfstring to provide with a textual
	representation of @*ref, instead of \hyperref, which, understandably
	breaks the contents.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	Document EPUB

	* doc/texinfo.texi (Output Formats, Generic Translator texi2any)
	(Invoking texi2any): Document EPUB3 output.

2022-07-27  Patrice Dumas  <pertusus@free.fr>

	Output Top node label in LaTeX

	* tp/Texinfo/Convert/LaTeX.pm (_convert): process the command
	normally even if the Top node was seen in order to have the Top
	label added.

	* tp/Texinfo/Convert/LaTeX.pm: update TODO comment for definitions.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	texi2any --help

	* tp/texi2any.pl: Fix help message so that default settings
	(including the fill column) are interpolated correctly.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	texi2any --epub3

	* NEWS, TODO: Update.
	* tp/texi2any.pl: Add --epub3 to usage message.  Edit
	usage message for format selectors to remove "rather than Info".

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	texi2any --epub3

	* tp/texi2any.pl: Add an option --epub3, which sets the output
	format to HTML and loads the 'epub3.pm' init file.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	@set txidefnamenospace in LaTeX

	* tp/Texinfo/Convert/LaTeX.pm (_convert) <@def*>:
	Implement txidefnamenospace flag to omit space between def
	name and arguments.  This rearranges and condenses the code,
	and uses gdt much less.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	Save txidefnamenospace

	* tp/Texinfo/ParserNonXS.pm (_parse_texi) <def command>,
	* tp/Texinfo/XS/parsetexi/handle_commands.c
	(handle_block_command) <def command>: If txidefnamenospace flag
	is set, set 'omit_def_name_space' extra value.
	* tp/t/19def.t (omit_def_space): New test.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	@set txidefnamenospace

	* doc/texinfo.tex (\defname):
	Use '@set txidefnamenospace' instead of '@clear txidefnamespace'
	to omit space.  This will ease implementation in the XS parser as
	it means we don't need to have flags set by default.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/LaTeX.pm (_convert) <@def*>:
	Combine code setting strings argument to gdt, for concision.

2022-07-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/LaTeX.pm (_convert) <deftypefnnewline>:
	Remove extra @* command at beginning of line.
	<@def*>: Use { and } for font change instead of \bgroup and \egroup.
	Reformat some code.

2022-07-26  Gavin Smith  <gavinsmith0123@gmail.com>

	@clear txidefnamespace

	* doc/texinfo.tex: Implement txidefnamespace conditional to
	allow omitting a space after a definition name.  This is important
	for m4 where the space is incorrect.  Report from Eric Blake.

2022-07-26  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi (Conventions): use 'Texinfo processors' instead
	of listing them.
	(@code{@@code}): use @command{texi2any} instead of 'Texinfo processors'
	as the customization variables are specific of texi2any.
	(Inserting Math): mandate the use of \ for math commands.
	(@samp{#line} and @TeX{}): use texi2any instead of makeinfo as there
	is already a reference to a node with texi2any in the reference node name.

	* doc/texinfo.texi: use @command instead of @code for commands.

2022-07-25  Patrice Dumas  <pertusus@free.fr>

	LaTeX cross-ref manual in slanted

	* tp/Texinfo/Convert/LaTeX.pm (_convert): use slanted for book
	argument of @*ref.

2022-07-25  Gavin Smith  <gavinsmith0123@gmail.com>

	Allow @{, @} in @copying block

	* doc/texinfo.tex (\macrobodyctxt): Move call to \usembodybackslash
	to sole calling site.
	(\copying): Call \macrobodyctxt instead of \scanctxt in order to
	change catcodes of { and }.  Use "other" space to find
	"@end copying" string.
	* doc/texinfo-tex-test.texi (Copying and captions): Test @{ and
	@} inside @copying.

2022-07-25  Gavin Smith  <gavinsmith0123@gmail.com>

	texinfo.tex scanning contexts

	* doc/texinfo.tex (\scanctxt):
	Set active backslash.  This means that active backslash is
	used instead of the "other" catcode when scanning arguments to
	@copying and @caption, but this appears not to make a difference
	as the arguments are not being expanded or executed straight away.
	(\scanargctxt): Remove this and replace calls with \scanctxt.

2022-07-25  Gavin Smith  <gavinsmith0123@gmail.com>

	texinfo.tex scanning contexts

	* doc/texinfo.tex (\scanctxt, \scanargctxt, \macrobodyctxt)
	(\macroargctxt, \macrolineargctxt): Simplify slightly by
	setting active newline in \scanctxt and "other" catcode for @,
	as \scanctxt is used by the other macros that need these changes.

	* doc/texinfo-tex-test.texi (Special characters in macro argument):
	New example, as this change may have affected braceless macro
	invocations.

2022-07-25  Patrice Dumas  <pertusus@free.fr>

	LaTeX @def* argument and category formated more like in TeX

	* tp/Texinfo/Convert/LaTeX.pm (_only_slanted_no_code_contents)
	(_convert): convert @def* line in code context, @def* category
	class to @code, and argument to slanted, not in code context,
	not in typewriter.

2022-07-25  Patrice Dumas  <pertusus@free.fr>

	Correct LaTeX output to be slanted when needed, and documentation

	* tp/Texinfo/Convert/LaTeX.pm (register_style_format_command)
	(%style_brace_format_command_new_commands)
	(%LaTeX_style_brace_commands, _latex_header, _convert):
	use slanted for @dfn, @var, as in texinfo.tex.  Also slanted
	for @cite, and, for @cite, not typewriter even in code context.

	* doc/texinfo.texi (@code{@@cite}, @code{@@dfn}): @dfn and
	@cite are slanted, not italic.

2022-07-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\unicodechardefs): Define the
	non-alphanumeric ASCII characters using \char TeX primitive.

2022-07-25  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.tex (\unicodechardefs): Provide definitions
	for many of the ASCII characters.
	(\DeclareUnicodeCharacter): Lower limit for definition
	from U+00A0 to U+0020.

2022-07-24  Patrice Dumas  <pertusus@free.fr>

	No @-commands in file names except for @@, @{ and @}

	* doc/texinfo.texi (@code{@@setfilename}, Using Include Files)
	(@code{@@verbatiminclude}): document that @value and @@, @{, @}
	and associated @-commands such as @atchar are the only @-commands
	allowed on @setfilename, @include and @verbatiminclude lines.

2022-07-24  Patrice Dumas  <pertusus@free.fr>

	* NEWS, tp/Texinfo/Convert/DocBook.pm (_convert),
	doc/texinfo.texi (@code{@@definfoenclose}): in DocBook,
	replace definfoenclose defined @-command by its argument
	as-is (as in LaTeX).  This is consistent with DocBook formatting
	in general, which matches better with printed output.

2022-07-24  Patrice Dumas  <pertusus@free.fr>

	Avoid Texinfo processor name when not needed, prefere texi2any

	* doc/texinfo.texi (Contents, Writing a Menu, Image Syntax)
	(Conditional Commands, Defining Macros, Invoking Macros)
	(Macro Details, HTML CSS, @code{@@documentdescription})
	(Command Contexts): do not name a Texinfo
	processor when features of the language or output expected from
	all the processors are described.
	(Macro Details): put information on @, in the by design limitations,
	not in TeX caveats, as it is also relevant for texi2any.
	(@code{@@alias}): use a similar wording with Macros for @alias
	identifiers.
	(Image Syntax): ignore text on compatibility for Info reader
	not compatible with a feature introduced in 2003.
	(@code{@@definfoenclose}): use @alias in TeX example, in order
	to use Texinfo @-commands and not TeX only commands.
	Remove the second definfoenclose example.
	(Formatting Partial Documents, Updating Nodes and Menus)
	(@command{texi2any} in Emacs, @code{texinfo-format} commands)
	(Texinfo Mode Summary, Running @code{Info-validate})
	(Info Format Indirect Table): use texi2any instead of makeinfo if
	there is already texi2any or a reference to a node with texi2any in
	the reference node name.  Use @command instead of @code for texi2any
	and makeinfo.  For some Emacs related nodes, use texi2any
	preferentially as those nodes are not often updated.
	(@command{texi2any} in Emacs, @command{texi2any} Preferred): prefer
	texi2any in node names.

2022-07-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* README-hacking: tab instead of spaces in git hook

2022-07-24  Gavin Smith  <gavinsmith0123@gmail.com>

	@def* in LaTeX

	* tp/Texinfo/Convert/LaTex.pm (_convert) <def_line>:
	Float category to end of line and typeset in typewriter font, as
	is done in texinfo.tex.

2022-07-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* NEWS: Update for variable renaming.

2022-07-24  Patrice Dumas  <pertusus@free.fr>

	Focus less on Info for Footnote Styles

	* doc/texinfo.texi (Footnote Styles): always use lower case end
	and separate styles names.  Focus less on Info, mix HTML information
	with Info information.
	(HTML Translation): remove the paragraph on Footnote styles, there
	is no reason to emphasize that feature here.  Remove an obsolete
	@ignore glock.
	(@code{@@settitle}): no need to refer to the Texinfo processor
	name.
	(Generating HTML, Escaping to HTML, HTML Splitting): use texi2any
	instead of makeinfo, if texi2any is already used or in a reference
	node name.

2022-07-24  Patrice Dumas  <pertusus@free.fr>

	Document LOCALE_ENCODING

	* doc/texinfo.texi (Other Customization Variables): add an entry
	for LOCALE_ENCODING.

2022-07-24  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi: fix the @detailmenu.

2022-07-23  Patrice Dumas  <pertusus@free.fr>

	Describe output file and encoding early. More semantic @title, etc.

	* doc/texinfo.texi (Minimum, @code{@@setfilename}): state the
	default output file name when the input file name extension is
	described, in 'Minimum'.
	texi2any does not need \input texinfo nor @bye, do not implicitly
	say that.
	(Minimum): give the information on the default encoding here, to
	have this information early in the manual.
	(Minimum, Texinfo File Header): treat @settitle as any other
	preamble @-command.
	(Texinfo File Header, @code{@@documentencoding}): use consistently
	'preamble' and not 'Texinfo preamble'.
	(@code{@@titlepage}, @code{@@title @@subtitle @@author}): insist
	less on the formatting of @title, @subtitle and @author, using wording
	less definitive on the formatting, as it is semantic and formatting
	could change over time or across formats.

2022-07-23  Gavin Smith  <gavinsmith0123@gmail.com>

	INPUT_FILE_NAME_ENCODING, OUTPUT_FILE_NAME_ENCODING documentation

	* doc/texinfo.texi (Other Customization Variables): Elaborate.

2022-07-23  Gavin Smith  <gavinsmith0123@gmail.com>

	INPUT_FILE_NAME_ENCODING, OUTPUT_FILE_NAME_ENCODING documentation

	* doc/texinfo.texi (Other Customization Variables): Update.

2022-07-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Give INPUT_FILE_NAME_ENCODING, OUTPUT_FILE_NAME_ENCODING priority

	* tp/Texinfo/Common.pm (@variable_string_settables):
	Add LOCALE_ENCODING.
	* tp/texi2any.pl: Save locale in LOCALE_ENCODING configuration
	variable.  Do not set INPUT_FILE_NAME_ENCODING or
	OUTPUT_FILE_NAME_ENCODING.  Do not provide a UTF-8 default value
	for the locale encoding.

	* tp/Texinfo/Convert/Converter.pm (encoded_input_file_name),
	* tp/Texinfo/Convert/Utils.pm
	(expand_verbatiminclude, encoded_output_file_name),
	* tp/Texinfo/ParserNonXS.pm (_encode_file_name),
	* tp/Texinfo/XS/parsetexi/input.c (encode_file_name):
	First check INPUT_FILE_NAME_ENCODING, then the document encoding
	if DOC_ENCODING_FOR_INPUT_FILE_NAME is set, and thirdly the locale
	encoding saved in LOCALE_ENCODING.  Likewise for
	OUTPUT_FILE_NAME_ENCODING and DOC_ENCODING_FOR_OUTPUT_FILE_NAME.
	(Note that Texinfo::Common::encode_file_name can be called
	with an undefined encoding argument, so things will likely work
	even if LOCALE_ENCODING ends up being undefined.)

	* tp/Texinfo/XS/parsetexi/input.c (locale_encoding),
	* tp/Texinfo/XS/parsetexi/api.c, tp/Texinfo/XS/parsetexi/Parsetexi.xs
	(set_locale_encoding): New.
	* tp/Texinfo/XS/parsetexi/Parsetexi.pm (parser):
	Propagate LOCALE_ENCODING setting.

	* tp/Texinfo/XS/parsetexi/input.c
	(locale_input_file_name_encoding, input_file_name_encoding),
	* tp/Texinfo/XS/parsetexi/api.c, tp/Texinfo/XS/parsetexi/Parsetexi.xs
	(set_locale_input_file_name_encoding, set_input_file_name_encoding):
	Rename.

	setting.
	(non_ascii_test_epub, non_ascii_test_rawtext): Delete duplicate
	COMMAND_LINE_ENCODING setting.

2022-07-23  Patrice Dumas  <pertusus@free.fr>

	Separate information on formatting directly Info files

	* doc/texinfo.texi (Formatting Info files, Unsplit and Tagify):
	Add 'Formatting Info files' at the section level to contain
	information on direct processing of Info files with Emacs.  It
	contains 'Tagifying' and 'Splitting', keeping from 'Tagifying'
	only the part about Tagifying, not the part about Info file
	validation.  Merge 'Unsplit' and 'Tagifying' as 'Unsplit and Tagify'
	in 'Running @code{Info-validate}' keeping only the information
	relevant for Info file validation.

2022-07-22  Gavin Smith  <gavinsmith0123@gmail.com>

	Rename LOCALE_INPUT_FILE_NAME_ENCODING

	* doc/texinfo.texi (Other Customization Variables):

	Update Emacs related documentation, other changes

	* doc/texinfo.texi (Printing with Emacs, Emacs Shell Printing): add
	the 'Printing with Emacs', rename 'Within Emacs' as 'Emacs Shell
	Printing', and put 'Emacs Shell Printing', 'Texinfo Mode Printing'
	and 'Compile-Command' in 'Printing with Emacs'.
	(Tag and Split Files, Splitting): update based on changes in Emacs,
	thanks to Robert Pluim information, texinfo-format-buffer always create a
	tag table.
	(Splitting): move up to the same level of 'Catching Mistakes'.
	(Installing Dir Entries, GNU Sample Texts): inform that @dircategory
	specify a manual category in addition to being used in Info (dir).
	(Running @code{Info-validate}, @code{Info-validate}): describe the
	use of CHECK_NORMAL_MENU_STRUCTURE to make more checks with makeinfo,
	and that makeinfo never checks that a Next pointer corresponds to
	a Prev pointer.  Write explicitly that a Next pointer always
	corresponding to a Prev pointer is not a strict requirement, but
	for 'standard' documents.

	* doc/texinfo.texi: other minor changes.

2022-07-21  Patrice Dumas  <pertusus@free.fr>

	Move Emacs multiple file updates nodes to Emacs mode node

	* doc/texinfo.texi (Update Multiple Files, Include Files Requirements)
	(Include Files, Other Updating Commands):
	rename '@code{texinfo-multiple-files-update}' as 'Update Multiple
	Files'.  Move 'Update Multiple Files' and 'Include Files Requirements'
	out of 'Include Files' to 'Updating Nodes and Menus' in Emacs
	Texinfo mode description.
	Move information related to texinfo-multiple-files-update from
	'Other Updating Commands' to 'Update Multiple Files'.

	* doc/texinfo.texi (Sample Include File): update and simplify the
	example.

2022-07-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Texinfo Preamble): Rename to "Preamble" and edit.

2022-07-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi
	(@setfilename): "Tell the name" -> "Give the name" in menu entries
	leading to this node.  Do not separate sentences with commas.  Other
	edits for grammar.
	(Titlepage & Copyright Page): "similar with" -> "similar to"
	(small): Remove mention of Texinfo-XML transliteration as not much
	information is given here.

2022-07-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi
	(Nodes): No need to compare cross-references with the "document
	structure".
	(Node Line Requirements): Avoid obscure word "unicity".  Tweak
	reference to node name quoting support.
	(Cross Reference Parts): Consistent referencing to xref targets.

2022-07-20  Gavin Smith  <gavinsmith0123@gmail.com>

	Edit recent changes for grammar and style and make other minor edits.

	* doc/texinfo.texi (Reporting Bugs, Histroy, Minimum, @settitle)

	(Defining New Texinfo Commands, @definfoenclose, Hardcopy with TeX)
	(Texinfo Mode Printing, Command List, Tips, @setchapternewpage)
	(@headings, Custom Headings, A4 Paper): Various fixes:

	- "Cause TeX to" was changed in some places to "Cause to" but the
	  result of this was ungrammatical in many places.
	- Do not use commas to separate sentences.
	- non printed -> non-printed

	(Hardcopy with TeX): Add anchor for old name.

	* NEWS: Remove entry about generating menus as this is not a
	new feature.

2022-07-20  Patrice Dumas  <pertusus@free.fr>

	Input/output encoding is used irrespective of @documentencoding

	* doc/texinfo.texi (@code{@@documentencoding}): the output of
	encoding information does not depends on @documentencoding being
	set.  Emphasize more than UTF-8 is the default encoding.
	Explain what --enable-encoding does for LaTeX.
	Correct the description for XML and DocBook, they are affected by
	@documentencoding and --enable-encoding.

	* doc/texinfo.texi (Invoking @command{texi2any}), tp/texi2any.pl:
	document what --enable-encoding does for HTML, TexinfoXML and DocBook.

2022-07-20  Patrice Dumas  <pertusus@free.fr>

	Describe @-commands roles in Command List, not formatting

	* doc/texinfo.texi (Command List): explain the role of the
	@-commands, not the formatting.  Avoid details on output
	format specificities when it is not crucial for the understanding
	of the @-command role.  Move or duplicate some information to the main
	nodes describing some @-commands.  Update some @-commands descriptions.
	(Command Contexts): explain @shortcaption context along with
	@caption.

2022-07-20  Patrice Dumas  <pertusus@free.fr>

	No HTML features list, explain how HTML evolves

	* doc/texinfo.texi (HTML Translation): do not list explicitly
	HTML features used, but rather explain how makeinfo implements
	latest standard features while trying to be backward compatible
	as best as possible too.

2022-07-20  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi (@code{@@setfilename}): state clearly that
	@setfilename is optionnal, and give some example where it could
	still be relevant.  Add an @anchor{Setting the Output File Name}
	and use it everywhere the reference is to the output fine name set,
	be it from @setfilename or from the input file name, and not
	directly about the @setfilename @-command.
	(@code{@@settitle}): advertise NO_TOP_NODE_OUTPUT as the best way
	to get a title similar with printed manuals in HTML.
	(Node Line Requirements): readd a sentence on constraints on
	spaces in menu entry node names, after testing that what matters
	are the internal spaces.
	(Menu Location): remove obsolete @ignore'ed block text.
	(Floats, @code{@@float}, @code{@@listoffloats}): information on
	floats with LaTeX.
	(Inserting Accents): adapt for changes in default encoding.
	(HTML Customization Variables): move USE_TITLEPAGE_FOR_TITLE and
	SHORT_TOC_LINK_TO_TOC to HTML Customization Variables.
	Explain why INDEX_SPECIAL_CHARS_WARNING is set to false in
	INDEX_SPECIAL_CHARS_WARNING explanation, refer to
	INDEX_SPECIAL_CHARS_WARNING in INFO_SPECIAL_CHARS_WARNING.
	(Generating HTML): mention that initialization files can be used
	to customize even more the HTML output. Give example of such files
	in Texinfo.  Link to the draft customization_api manual.
	(HTML CSS): @ignore text about texinfo-bright-colors.css as it
	is not in Texinfo anymore.

	* doc/texinfo.texi: misc other changes, in particular remove
	information on Texinfo XML transliteration when it is simply said that
	a transliteration is produced.

2022-07-18  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi: add additional information on DocBook output.
	(Generating HTML): remove the sentence saying that DocBook and
	XML output are not described in detail, they are correctly described.

2022-07-18  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi (@command{latex2html} Customization Variables):
	write only once that the customization variables are only relevant
	if using latex2html.

2022-07-18  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Common.pm (%default_main_program_command_line_options):
	add 'SILENT' for --silent for completeness.  It is not used anywhere.

2022-07-18  Patrice Dumas  <pertusus@free.fr>

	Simplify node names information, add more on explicit pointers

	* doc/texinfo.texi (Node Line Requirements): simplify information
	on node names requirements to match with current implementation
	and avoid implementation details.
	(First Node): Top Prev node is not set in the usual case.
	(Texinfo Document Structure, Node Menu Illustration): move the
	information from the Note in Node Menu Illustration to
	Texinfo Document Structure to explain better that Next and Prev
	at the same hierarchical level earlier.  Remove the Note as it
	is redundant with other explanations (before and after).
	Be more explicit in the examples on the differences between
	automatic and explicit node pointers.  Add a paragraph to explain
	that technically explicit node pointers can lead anywhere, but
	that it is a bad idea to use that feature.
	(Menus): be more explicit that menus need not to be written in
	a hierarchically organized manual with automatic pointers unless
	specific formatting is wanted.

2022-07-17  Patrice Dumas  <pertusus@free.fr>

	Document float labels and anchors are used like nodes, other changes

	* doc/texinfo.texi (Nodes, Node Line Requirements, References)
	(Cross Reference Parts, @code{@@anchor})
	(HTML Xref Node Name Expansion): document systematically
	that anchor and float labels are equivalent with
	node names and unicity is for all of those names usable
	as cross references locations.
	(Node Names): instead of telling never to change a node name,
	propose to replace by an anchor here too, as in the @anchor
	section.
	(Nodes, Writing a Node, Writing a Menu): recommend less
	prominently the usual structuring following the sectioning
	structure, as other structures such as guide/topic structure
	would be relevant.
	(Node Line Requirements): link to INFO_SPECIAL_CHARS_QUOTE
	to state that the limitation in node names will be removed some day.

2022-07-17  Patrice Dumas  <pertusus@free.fr>

	Documentation: LaTeX output, move Emacs related info, other changes

	* doc/texinfo.texi: edit to use printed output instead of @TeX{}
	if also relevant for LaTeX, and add specific informations
	for LaTeX output.
	(Hardcopy with @TeX{}): rename Hardcopy as Hardcopy with @TeX{}.
	(Minimum, Emacs Editing, Sample Include File)
	(Invoking @command{texi2any}): discourage using .tex as extension
	for Texinfo documents, encourage .texi.  Remove duplicate
	information on extensions in Emacs Editing node.
	(Texinfo File Header, Writing a Node, Texinfo Mode Printing)
	(Updating Commands, @code{@@smallbook}, Preferred): remove or
	move Emacs specific information.  Also recall that using automatic
	pointers and menus is possible and usually better.
	(Start of Header, End of Header): merge as Start and End of Header
	and put after Texinfo Preamble node.
	(Reporting Bugs): link to GNU Coding Standards
	instead of Emacs manual, and propose diff -u too.
	(Output Formats, Short Sample, The Top Node, Master Menu Parts)
	(Nodes, @code{@@top} Command, Fonts, PDF Output): remove some
	text with erroneous, redundant or useless information.
	(Adding Output Formats): link to tp_api.
	(History): update on Multilingual support, to take into account
	that there is now C again.  Add a sentence to describe that there
	was no back-end contribution.
	(Texinfo Document Structure, Node Menu Illustration): do not
	present the usual structuring following the sectioning structure
	as the only one recommended.  Other structures (for example the
	guide/topic structure of the Mallard language) would be equally
	relevant.

	* tp/texi2any.pl, doc/texinfo.texi (Invoking @command{texi2any}):
	add --iflatex and --no-iflatex.

	* doc/texinfo.texi (Menus), NEWS: document that a menu in Info output
	is automatically added if there is no @menu at all in a node with
	automatic directions.

2022-07-05  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/ParagraphNonXS.pm (set_space_protection),
	* tp/Texinfo/XS/xspara.c (xs_set_space_protection):
	Remove code making end of sentence up to two spaces as it is not
	clear that this is necessary or correct.

2022-06-05  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi: Change all Wikipedia links to use https.
	From Tzvetelin Katchov <katchov@gnu.org>.

2022-06-04  Patrice Dumas  <pertusus@free.fr>

	Document strict API use in comments when the API is not used

	* tp/Texinfo/Convert/HTML.pm: use # API info: comments to
	document what strict API use would have been when the API is not
	used for speed.

	* doc/customization_api.texi (Init File Basics, Basic Formatting
	Customization): document # API info: comments. Document that
	customized format_protect_text function may not be called everywhere.

2022-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	Cast for isalpha and isalnum arguments

	* Texinfo/XS/parsetexi/end_line.c (end_line_starting_block)

2022-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	Joint tree transformation

	* tp/Texinfo/Common.pm (html_joint_transformation):
	Peform both the 'move_index_entries_after_items' and the
	'relate_index_entries_to_table_entries_in_tree' transformations
	together.
	* tp/texi2any.pl: Use this for HTML and also LaTeX.

	This is much faster because of the slowness of recursively
	traversing the parse tree with Perl subroutine calls.  It means
	we traverse the tree one fewer time.

2022-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/HTML.pm (_convert_text):
	Call _default_format_protect_text without method call syntax.

	Simplify and inline at call sites.

2022-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	texi2any --html performance improvement

	* tp/Texinfo/Convert/HTML.pm (_convert_text):
	Call _default_format_protect_text directly instead of via
	formatting_function, as this is a heavily used function.

	Note: init/html32.pm overrode this function so as not to
	use the &quot entity, so this likely is ineffectual now.

2022-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	texi2any --html performance improvement

	* tp/Texinfo/Convert/HTML.pm (_convert_text):
	Hard-code access to 'conf' array rather than calling
	get_conf method.  This is a heavily used function.
	Profiled with Devel::NYTProf.

2022-06-03  Gavin Smith  <gavinsmith0123@gmail.com>

	texi2any --html performance improvement

	* tp/Texinfo/Convert/HTML.pm (_convert): Cache debug flag

	Devel::NYTProf.

2022-06-03  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (HTML Translation): Edit and trim.

	tests to use UTF-8 encoding where required.

2022-05-31  Gavin Smith  <gavinsmith0123@gmail.com>

	of whitespace characters expanding on ASCII vs. Unicode
	spaces and comment out some excessive detail about
	form feeds.

	Gavin idea.

2022-05-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Rename LOCALE_OUTPUT_ENCODING_NAME to MESSAGE_ENCODING. 

	* tp/Texinfo/Common.pm (@variable_string_settables):
	Rename LOCALE_OUTPUT_ENCODING_NAME to MESSAGE_ENCODING. 
	* NEWS, doc/texinfo.texi: Update.

2022-05-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Rename DATA_INPUT_ENCODING_NAME to COMMAND_LINE_ENCODING.

	* NEWS, doc/texinfo.texi: Do the needful.

2022-05-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Rename DATA_INPUT_ENCODING_NAME to COMMAND_LINE_ENCODING.

	* tp/Texinfo/Common.pm (@variable_string_settables):
	Rename DATA_INPUT_ENCODING_NAME to COMMAND_LINE_ENCODING.

2022-05-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* NEWS: Mention DATA_INPUT_ENCODING_NAME.

2022-05-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi: Remove link to old SVN repository in comment.

2022-05-08  Gavin Smith  <gavinsmith0123@gmail.com>

	Line breaking fix in test suite

	* tp/tests/coverage_macro.texi:
	Add blank line in attempt to get consistent line breaking
	decisions on Solaris, where wcwidth returns 2 for more characters.

2022-05-08  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/plaintext_tests.t (non_break_spaces):
	Skip test on older Perl.

2022-05-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Reinstate empty contents

	Reverse the following change, from 2022-04-20.

	* tp/Texinfo/Common.pm (parse_node_manual), tp/Texinfo/ParserNonXS.pm
	(_isolate_last_space, _parse_node_manual, _end_line, _parse_texi):
	do not set contents for type 'menu_entry_name' and 'menu_entry_node'
	if empty.

	With this reversion, I have run the test suite to pass both under
	TEXINFO_XS=omit and TEXINFO_XS_PARSER=0.

	There were various test failures with TEXINFO_XS=omit and
	TEXINFO_XS_PARSER=0 due to inconsistent results.

	Where an element can have contents, it will be simplest if
	it always has the contents element, as in the C code there
	is no distinction between an empty contents array and no
	contents at all.

2022-05-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix segfault for empty contents

	* tp/Texinfo/XS/misc.c (xs_merge_text): Check if the
	contents array was defined.
	* tp/Texinfo/XS/end_line.c (parse_node_manual): Remove confusing
	comment.

	Since recent change, there could be a segfault under
	TEXINFO_XS_PARSER=0 due to the contents array not being defined.

2022-04-20  Patrice Dumas  <pertusus@free.fr>

	Fix both parsers to do the same tree with empty menu entry nodes

	* tp/Texinfo/XS/parsetexi/menus.c
	(register_extra_menu_entry_information): to determine that there
	is no node content returned by parse_node_manual(), check that
	manual_content and node_content fields are both null, as
	parsed_entry_node is never null.  parsed_entry_node cannot be null
	because the return of parse_node_manual() can be used in nodes_manuals
	which is null delimited.

	* tp/Texinfo/Common.pm (parse_node_manual), tp/Texinfo/ParserNonXS.pm
	(_isolate_last_space, _parse_node_manual, _end_line, _parse_texi):
	do not set contents for type 'menu_entry_name' and 'menu_entry_node'
	if empty.

	* tp/Texinfo/ParserNonXS.pm (_register_extra_menu_entry_information):
	do not call Texinfo::Convert::NodeNameNormalization::normalize_node
	to check if node is empty, simply check that it has contents as is
	done in the XS Parser.

2022-04-19  Gavin Smith  <gavinsmith0123@gmail.com>

	vertical tab

	* tp/Texinfo/XS/parsetexi/parser.c
	(whitespace_chars, whitespace_chars_except_newline):
	Add \v in order to be consistent with \s regex class in
	newer Perl.  From Patrice.

2022-04-18  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Structuring.pm (associate_internal_references): check
	reference only if there is a 'node_content'.

2022-04-18  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove special treatment of \r in paragraph formatter

	* tp/Texinfo/Convert/ParagraphNonXS.pm (add_text),
	* tp/Texinfo/XS/xspara.c (xspara_add_text)
	<space not at end of sentence>: Remove special handling of
	carriage return.  The code is somewhat hard to follow and it
	should be unlikely that a carriage return makes it to this code.

2022-04-18  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Structuring.pm (new_node_menu_entry)
	(new_complete_node_menu): handle node with {'extra'}->{'node_content'}
	undef, as happens for node with empty argument.

2022-04-18  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/ParagraphNonXS.pm (add_text): consider \r
	to end a line, as in the XS code.

2022-04-17  Patrice Dumas  <pertusus@free.fr>

	Avoid duplication in @detailmenu master menu output by pod2texi

	* Pod-Simple-Texinfo/pod2texi.pl (_fix_texinfo_tree): call
	Texinfo::Structuring::associate_internal_references() to have

	similar code.

	* tp/Texinfo/ParserNonXS.pm (_register_extra_menu_entry_information):
	no need to delete menu entry 'normalized' as it is not set.

	* tp/Texinfo/Structuring.pm, tp/Texinfo/ParserNonXS.pm: minor changes
	in code style, comments and POD.

2022-04-14  Gavin Smith  <gavinsmith0123@gmail.com>

	ASCII_PUNCTUATION for some tests

	* tp/tests/layout/list-of-tests
	(formatting_info, formatting_plaintext): Set ASCII_PUNCTUATION for

2022-04-14  Gavin Smith  <gavinsmith0123@gmail.com>

	Change locale for tp/tests

	* tp/tests/run_parser_all.sh: Change LC_ALL and LANGUAGE
	from C.UTF-8 to en_US.UTF-8.  This is an attempt to make the
	tests run on more systems.  On one system without a C.UTF-8
	locale, Perl printed:

	command associated with both a part and a node with the first
	appearing.  Do not add partinfo if the part is associated with a
	sectioning command, the content of the part will be at the beginning
	of the sectioning command.  This is erroneous to have non empty part
	anyway.

2022-03-12  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/DocBook.pm (_convert): open the @path associated

	to undef, and have NO_TOP_NODE_OUTPUT set SHOW_TITLE to 1
	if SHOW_TITLE is undef.  Set USE_TITLEPAGE_FOR_TITLE to 1.
	That way, there is no title in the default case, as it is
	redundant with the @top header, there is a title only if
	NO_TOP_NODE_OUTPUT is set.

2022-03-10  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi (Other Customization Variables): expand

	appears on a test line, skip the test if the recoding of
	file names failed.

	* tp/tests/run_parser_all.sh: if a prerequisite for a test is
	missing, such as not recoded file names needed, or latex2html
	or tex4ht not present, and only one test is run, return 77 to
	have the test marked as skipped instead of succeeding.

2022-03-10  Patrice Dumas  <pertusus@free.fr>

	* tp/tests/Makefile.am (check_DATA): copy and change file name
	encoding from utf8 to latin1 for latin1 encoded file name for tests.

	customization variable.  If set, the Top node content output is
	discarded.  If set and USE_TITLEPAGE_FOR_TITLE is undef (the default
	now), set USE_TITLEPAGE_FOR_TITLE.  Set NO_TOP_NODE_OUTPUT in
	tp/init/book.pm and tp/init/epub3.pm.

	Find first index entry under initial substring search

	* info/indices.c (next_index_match): Reset index search by
	setting index to -1 index instead of 0.  Otherwise the first
	index entry is skipped when checking for initial substrings.
	The very first index entry in an Info file would not be found
	with a non-exact search.

	Report from Sergey Matveev <stargrave@stargrave.org>.

	(l2h_change_image_file_names, l2h_finish, l2h_from_cache): do
	not use a volume, consistently with the HTML converter.
	Do not force encoding variables to UTF-8, but instead encode
	separately the directory as in the HTML Converter and the files
	related to latex2html in UTF-8, such that the files output by
	latex2html only contains UTF-8.  Also encode separately
	the file names in the latex2html command line and the remaining
	of the command line.  Based on Gavin report.

	Fix latex2html init file under Latin-1 locale

	* tp/init/latex2html.pm (l2h_change_image_file_name):
	Hardcode the use of UTF-8 to encode image file names, as the
	calling code in l2h_init_from_html set a ':utf8' filter on the
	file the file names were taken from.  Call File::Spec->catpath
	on already-encoded strings rather than encoding afterwards.

2022-03-06  Patrice Dumas  <pertusus@free.fr>

	* tp/tests/formatting/list-of-tests (non_ascii_test_epub):
	Enable test and commit results.

2022-02-26  Gavin Smith  <gavinsmith0123@gmail.com>

	Encode @setfilename argument

	* tp/Texinfo/Convert/Converter.pm (determine_files_and_directory):
	Call Texinfo::Common::encode_file_name on @setfilename argument.

	This mean that @setfilename works properly for a
	'@documentencoding ISO-8859-1' and also means that
	the OUTDIR customization variable works correctly.

2022-02-24  Gavin Smith  <gavinsmith0123@gmail.com>

	UTF-8 flag on strings for XS parser

	* tp/Texinfo/XS/parsetexi/api.c (newSVpv_utf8): New function.

	tp/Texinfo/Convert/LaTeX.pm, tp/Texinfo/Convert/Utils.pm
	(expand_verbatiminclude), tp/Texinfo/ParserNonXS.pm: put the
	main function encode_file_name() doing file name encoding
	in Texinfo::Common and use encoded_file_name for Converters.
	Return the file name encoding if there is a need to decode
	the file name for error messages.

2022-02-24  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix XS configure check

	* tp/Texinfo/XSLoader.pm: Put 'require Texinfo::ModulePath'
	inside an eval block and provide default values if the module

	configure check using TestXS.pm.  Report from Patrice.

2022-02-23  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Common.pm (locate_include_file),

	tp/Texinfo/Convert/LaTeX.pm (_convert),
	tp/Texinfo/Convert/Utils.pm (expand_verbatiminclude),
	tp/Texinfo/ParserNonXS.pm (_end_line): encode file name before
	calling locate_include_file() in order to be able to pass file
	names already encoded (case of CSS_FILES) and find the information
	in different structures in converters and NonXS Parser.
	Note in comments that no information source is available in
	Texinfo/Convert/Utils.pm expand_verbatiminclude().

2022-02-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Recode filenames into input encoding

	* tp/Texinfo/Common.pm (locale_include_file): Recode
	the filename into the input encoding even if it is not UTF-8.

2022-02-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Get errors from XS code without using eval

	(get_errors): New function to create error list.
	* tp/Texinfo/XS/parsetexi/errors.c (dump_errors): Function removed.
	* tp/Texinfo/XS/parsetexi/Parsetexi.pm: Call it to get the errors
	and warnings from the XS module.

	This allows better control of string encodings for messages
	and filenames.  It may also be faster than calling eval.

2022-02-23  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/XS/parsetexi/Parsetexi.pm (_get_errors): encode
	file name for consistency with file names being bytes, as a temporary
	measure before a better interface is implemented.

	* tp/Texinfo/Report.pm: rename variables.

2022-02-22  Patrice Dumas  <pertusus@free.fr>

	Decode inputs for encoded characters

	Always use installed translated messages

	* tp/Texinfo/XS/parsetexi/api.c (init),
	* tp/texi2any.pl: Unconditionally use installed messages regardless
	of whether the program is installed or not.  Although it would be
	better to use uninstalled messages for this, this hasn't been
	implemented, and having access to translated messages when uninstalled
	will make testing the translations easier.  Remove reference to
	a non-existent 'maintain/regenerate_perl_module_files.sh' script.

2022-02-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/ModulePath.pm.in: Add a comment warning against
	using the module more than once.

2022-02-22  Gavin Smith  <gavinsmith0123@gmail.com>

       Fix translation of messages with XS modules

       * tp/Texinfo/XSLoader.pm: require rather than use Texinfo::ModulePath
       to prevent initialization being done again, incorrectly.  This led
       to incorrect locale dirs being used due to
       $Texinfo::ModulePath::texinfo_uninstalled being reset.

2022-02-22  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/XS/parsetexi/api.c (build_texinfo_tree): return
	an empty element instead of segfaulting if build_texinfo_tree()

	with the current code.

2022-02-22  Gavin Smith  <gavinsmith0123@gmail.com>

	Avoid segfault in XS code for missing input file

	* tp/Texinfo/XS/parsetexi/api.c (parse_file): Correctly propagate

	messages line numbers.

2022-02-21  Gavin Smith  <gavinsmith0123@gmail.com>

	No encoding for filenames in error messages.

	* tp/Texinfo/Report.pm (line_warn, line_error):
	Do not prepend filename or line number to error messages.
	* tp/texi2any.pl (handle_errors): Do it here, without encoding
	the filename.  Handle stripping directories from the filenames
	for the test suite here.
	* tp/t/test_parse_texi_line.t, tp/t/test_parser_registrar.t,
        tp/t/test_protect_hashchar_at_line_beginning.t: Remove line numbers

2022-02-21  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/LaTeX.pm (_latex_header): readd framemethod=tikz
	option for mdframed for roundcorners for @cartouche formatting
	now that the \fbox in sectioning command issue has been solved.

2022-02-21  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/LaTeX.pm (_convert): add a context if
	in heading formatting.  In heading formating, use 'error'
	as a string instead of a \fbox for @error formatting in
	contents bookmark string using \texorpdfstring{}.
	Based on Ulrike Fischer suggestion:
	https://github.com/latex3/hyperref/issues/207#issuecomment-920712424

2022-02-20  Patrice Dumas  <pertusus@free.fr>

	names.  Separate mappings of koi8-u and koi8-r.

	* tp/Texinfo/Encoding.pm (encoding_alias): remove
	%eight_bit_encoding_aliases.  Use my, not our for variables not used
	elsewhere.

	* util/txixml2texi.pl: use directly Encode::resolve_alias() instead of
	Texinfo::Encoding::encoding_alias().

	* tp/Texinfo/XS/parsetexi/end_line.c (end_line_misc_line): add latin-1
	mapping.  Remove impossible or incorrect mappings from encoding_map.

	@multitable.

2022-01-18  Patrice Dumas  <pertusus@free.fr>

	Put texinfo_document.pot in git and update po files

	* .gitignore, po_document/texinfo_document.pot: ship
	po_document/texinfo_document.pot.  It is inconvenient as it changes

	* po_document/*.po: regenerate.

2022-01-16  Gavin Smith  <gavinsmith0123@gmail.com>

2022-01-16  Patrice Dumas  <pertusus@free.fr>

	Use /a regexp modifier to consider only ascii spaces in matching

	* tp/Texinfo/ParserNonXS.pm: use /a modifier to match or exclude
	only ascii spaces, as \s can also mean non ascii spaces.  In general
	we want spaces to be only ascii spaces, because it makes more sense to
	consider at least most non ascii spaces as chraracters and not spaces,
	but also because it matches with the XS parser definition of spaces.

2022-01-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Use that code to set documentlanguage in main program configuration.

2022-01-16  Patrice Dumas  <pertusus@free.fr>

	* po_document/POTFILES.in: add tp/Texinfo/Translations.pm.

	* tp/Texinfo/Translations.pm: mark explicitly strings that are to be

	as it is needed for regenerate_master_menu.

	* tp/Texinfo/Config.pm (new, get_conf, set_conf): reset the additional
	configuration each time new is called.  Add a flat to the
	configuration to distinguish the standalone configuration as used
	in the tests or the configuration for the main program.  For the main
	program do not override command line.

	* tp/Texinfo/Transformations.pm: mark the translation especially.

	* .gitignore, tp/tests/Makefile.am,
	tp/tests/many_input_files/Makefile.am: add new tests for many_input_files.

	(_register_global_command): no dynamic 'global_commands', use directly
	%global_multiple_commands.

	* tp/Texinfo/ParserNonXS.pm (parser): ignore code setting user defined
	information, as it cannot happen now that the configuration keys are
	not in %parser_state_configuration anymore, and also because there is
	no such configuration possible in the XS parser.

2022-01-15  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/ParserNonXS.pm (%parser_state_initialization, parser)

	tp/init/book.pm: move
	section_level() from Texinfo::Structuring to Texinfo::Common to

	page if @settitle is not set.

	* doc/texinfo.texi (@code{@@copying}, @code{@@insertcopying}):
	clarify that in XML and DocBook @copying text is in appropriate

	* tp/Texinfo/Convert/HTML.pm (%css_map, _convert_preformatted_type):
	set a class for menu entry description in preformatted in menu to

	* tp/Texinfo/Convert/HTML.pm (_default_format_navigation_panel):

	  Our thanks go out to all who helped improve this work,
	  particularly to @w{Francois Pinard} and
	  @w{David D.@: Zuhn}, who tirelessly recorded and reported
	  mistakes and obscurities; our special thanks go to
	  @w{Melissa Weisshaus} for her frequent and often tedious reviews
	  of nearly similar editions.  Our mistakes are our own.

	Later, by Texinfo 4.0 (September 1999), this was changed to add:
	
	  The indefatigable Eli Zaretskii and Andreas Schwab have
	  provided patches beyond counting.  Zack Weinberg did the
	  impossible by implementing the macro syntax in @file{texinfo.tex}.
	
	Karl Berry likely wrote this latter text.

	<tt> is a deprecated tag in HTML5, although it is harmless

	- The argument was a single character
	- There were already quotes of some kind enclosing the argument
	- It's evident from context or the argument itself that the argument
	  could be computer code (e.g. name of a Usenet newsgroup)

	* tp/Texinfo/ParserNonXS.pm (%set_flag_index_char_ignore)
	(_enter_index_entry), tp/Texinfo/Structuring.pm
	(index_entry_sort_string): add the ignored characters based

2021-09-06  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/DocBook.pm (%defaults, convert, convert_tree)
	($DEFAULT_LANG, output, _convert): set the default for

	lang attribute for the whole document if documentlanguage is undef.
	Use a stack of languages, with current documentlanguage value
	pushed at sectioning command opening, removed when a sectioning

	* tp/Texinfo/Convert/Info.pm (_info_header),
	tp/Texinfo/Convert/Plaintext.pm (get_informative_global_commands):
	pass @informative_global_commands to with

2021-09-06  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/TexinfoXML.pm (format_header): remove document

	process in argument.
	In Texinfo::Convert::HTML, use set_global_document_commands()
	in more specific ways specifying the changed variables and restoring
	after use if not needed anymore.  For contents, the variables are set
	early and once for all as it needs to be known in advance in many
	codes.

	* tp/Texinfo/Convert/HTML.pm (_convert_def_line_type): fix the
	case of @deftypefn and similar commands with @deftypefnnewline
	on and no argument, the type and name were missing.

	do not merge the indices, it is done elsewhere.


2021-09-05  Patrice Dumas  <pertusus@free.fr>

	* texi2any.pl: use Storable::dclone to copy parser configuration
	for each file and command line options for each file.  A shallow
	copy is not enough to make sure that the initial information is not
	modified with arrays or hashes.  This happened in practice for
	'INCLUDE_DIRECTORIES'.

2021-09-05  Patrice Dumas  <pertusus@free.fr>

	Avoid unnecessary documentlanguage extra value

	* tp/Texinfo/XS/parsetexi/parser.c (wipe_global_info): Set
	global_documentlanguage to null rather than an empty string.
	This avoids a "documentlanguage" key being set on some @def*

	Most of the functions are moved to the newly created
	Texinfo::Convert::Utils file which groups miscellaneous functions
	usable in simple converters, in practice functions used by

2021-09-03  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/Converter.pm, tp/Texinfo/Convert/DocBook.pm,
	tp/Texinfo/Convert/HTML.pm, tp/Texinfo/Convert/TexinfoXML.pm,
	tp/init/chm.pm, tp/init/html32.pm, util/txixml2texi.pl: replace
	commands_formatting with no_arg_commands_formatting to be more
	precise.

2021-09-03  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Common.pm (%default_main_program_command_line_options),
	tp/Texinfo/Config.pm (GNUT_set_main_program_default,
	Texinfo::MainConfig, new, get_conf, set_conf), texi2any.pl
	(set_main_program_default): add a scope with functions that
	mimics parser or converter with get_conf() and set_conf()
	methods but using directly Texinfo::Config informations.
	This allows to set a $main_configuration object in
	main program that is passed to functions that need information.
	Used in tests too, simply setting a hash reference and not accessing
	Texinfo::Config informations.
	handle FORMAT_MENU and CHECK_NORMAL_MENU_STRUCTURE more like a
	normal main program option.
	

	* tp/Texinfo/Common.pm (%default_structure_customization_values),
	tp/Texinfo/XS/parsetexi/Parsetexi.pm, tp/Texinfo/ParserNonXS.pm:
	remove %default_structure_customization_values.

	* tp/Texinfo/Common.pm (set_output_encodings),
	tp/Texinfo/Convert/Converter.pm (converter), texi2any.pl: add
	set_output_encodings(), based on Texinfo::Converter::Convert
	to call on main program configuration for
	Texinfo::Common::output_files_open_out().

2021-09-02  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/Converter.pm (converter): set
	$converter->{'converter_init_conf'} to the configuration
	options obtained after setting the defaults and applying
	the configuration passed as argument.

	* tp/Texinfo/Convert/Converter.pm (_set_global_multiple_commands):
	rename $multiple_commands_index as $commands_location.

2021-09-02  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Common.pm, tp/Texinfo/Convert/Converter.pm,
	tp/texi2any.pl: add more default values for command
	line options and customizations, separating specific main
	program and parser customization options, and command line
	set from other options.  Use the defaults in
	Texinfo::Convert::Converter and in texi2any.pl.

	* tp/Texinfo/Config.pm (texinfo_add_to_option_list)
	(texinfo_remove_from_option_list), tp/texi2any.pl,
	tp/t/init/t2h_singular.init: handle list options differently than
	string options.  Indeed, the lists need to be defined in the
	main program, therefore the main program list options would
	always take precedence if there is a precedence, and the list
	options set from init file would not have any effect. For
	list options, items are added and removed by calls to
	texinfo_add_to_option_list and texinfo_remove_from_option_list,
	be it from command line or init files, there is no precedence,
	but the order of calls matter.
	Rename $default_options as $main_program_default_options.

	* tp/Texinfo/Convert/Converter.pm, tp/Texinfo/Convert/HTML.pm,
	tp/Texinfo/Convert/Unicode.pm, tp/Texinfo/Structuring.pm,
	tp/Texinfo/XS/parsetexi/Parsetexi.pm, tp/init/chm.pm: load
	needed used modules explicitly.
	* tp/Texinfo/Convert/Text.pm: do not inherit
	Texinfo::Convert::Converter.

	* tp/Texinfo/Convert/Converter.pm, tp/Texinfo/Convert/Text.pm,
	tp/texi2any.pl, tp/t/init/t2h_singular.init, tp/texi2any.pl:
	handle 'EXPANDED_FORMATS' like a normal customization option in
	converters, in particular replacing 'expanded_formats'.

2021-09-02  Patrice Dumas  <pertusus@free.fr>

	* NEWS: document that L2H was removed.

	* tp/Texinfo/Config.pm (_GNUT_map_obsolete_options),
	(texinfo_set_from_init_file, GNUT_set_from_cmdline): 
	add _GNUT_map_obsolete_options to map obsolete options
	to current options.
	add _GNUT in front of internal functions starting with _.

2021-09-02  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/XS/parsetexi/Parsetexi.pm (_get_error_registrar)
	(parse_texi_file, _get_errors): setup an error registrar
	to output the error message obtained before tree parsing.

	* tp/init/latex2html.pm (l2h_to_html): check that the
	command is set.

2021-09-02  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/Converter.pm (converter_global_commands),
	tp/Texinfo/Convert/HTML.pm (output):
	handle the global unique commands similarly with the global
	multiple commands.  remove now unused converter_global_commands().
	Modify _set_global_multiple_commands such that it only set to the
	first, last or initial configuration values (replacing
	_unset_global_multiple_commands).  Rename 'conf_default'
	as 'converter_init_conf' and add 'output_init_conf' for
	converters that modify the initial configuration per output,
	currently HTML.
	* tp/Texinfo/Common.pm (%document_settable_at_commands):
	add as a merge of %document_settable_multiple_at_commands and
	%document_settable_unique_at_commands.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Common.pm (%document_settable_at_commands)
	(%document_settable_multiple_at_commands): rename
	%document_settable_at_commands as
	%document_settable_multiple_at_commands.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* doc/texinfo.texi (HTML Customization Variables)
	(@command{latex2html} Customization Variables, @command{texi2html})
	tp/Texinfo/Common.pm (@variable_string_settables)
	tp/texi2any.pl: remove L2H.  HTML_MATH should be set to l2h
	only.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Common.pm (@variable_other_settables),
	tp/Texinfo/Convert/IXIN.pm (output_ixin),
	tp/Texinfo/Convert/IXINSXML.pm (%defaults):
	remove completely 'GLOBAL_COMMANDS'.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Convert/HTML.pm (converter_initialize): do not
	allow customization of 'commands_args'.  It is not already used
	and it is better to avoid making such changes which amounts
	to changing the Texinfo @-commands arguments meaning.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* util/texi-elements-by-size: use $parser->registered_errors().

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Common.pm (%default_parser_customization_values)
	(@variable_other_settables, locate_include_file)
	(_convert_text_options),
	tp/Texinfo/Convert/Converter.pm (%all_converters_defaults),
	tp/Texinfo/Convert/Text.pm (_code_options, convert_to_text)
	(_convert), tp/Texinfo/ParserNonXS.pm (%parser_state_configuration),
	tp/Texinfo/XS/parsetexi/Parsetexi.pm (parser), tp/texi2any.pl:
	turn 'include_directories' to a normal conf variable, renamed
	as 'INCLUDE_DIRECTORIES'.  As a consequence, locate_include_file
	now uses get_conf, which means that the $configurations_informations
	need to be blessed.  bless $options in Texinfo::Convert::Text
	convert_to_text() and instead of replacing the $options with
	the _code_options() function, use a state in '_code_options'
	to modify transiently instead of replacing each time code type
	formatting is needed.

	* tp/Texinfo/Config.pm (GNUT_load_config, GNUT_initialize_config)
	(_document_warn), tp/texi2any.pl: rename GNUT_load_config() as
	GNUT_initialize_config().  Pass $real_command_name and return
	$options, renamed $init_files_options.

	* tp/texi2any.pl (normalize_config, process_config): rename
	normalize_config() as process_config().
	Do not modify $cmdline_options after the first file, copy and
	modify.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Config.pm (texinfo_register_formatting_function),
	tp/Texinfo/Convert/HTML.pm (converter_initialize, run_stage_handlers):
	do not check the validity of texinfo_register_formatting_function()
	registered functions in Texinfo::Config but in Texinfo::Convert::HTML
	in converter_initialize().  Do not check that the stage handler is
	valid in Convert::HTML in run_stage_handlers() as it has already been
	done in Texinfo::Config.  This allows to avoid loading the
	Convert::HTML module early.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Config.pm (GNUT_get_stage_handlers)
	(GNUT_get_formatting_references, GNUT_get_commands_conversion)
	(GNUT_get_types_conversion), tp/Texinfo/Convert/HTML.pm:
	use a proper interface between Texinfo::Config and
	Texinfo::Convert::HTML for handlers.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Config.pm, texi2any.pl, tp/init/*.pm, tp/t/init/*.init: 
	rename _load_init_file as GNUT_load_init_file,
	_load_config as GNUT_load_config, set_from_init_file as
	texinfo_set_from_init_file, set_from_cmdline as GNUT_set_from_cmdline
	and get_conf as texinfo_get_conf to follow the convention that
	functions that should not be called by user init files codes are
	prefixed by GNUT_ while functions that can be called by user init
	files codes are prefixed by texinfo_.

	* tp/Texinfo/Config.pm: use explicitly Texinfo::Common for __(
	instead of using main program function.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Config.pm, texi2any.pl, tp/Texinfo/Convert/HTML.pm,
	tp/Makefile.am (dist_modules_DATA): put Texinfo::Config namespace
	in a separate file.  This is not perfect as Texinfo::Config is still
	entangled with Texinfo::Convert::HTML.  In particular delayed loading
	of converter modules in texi2any.pl is now ineffective for
	Texinfo::Convert::HTML.

2021-09-01  Patrice Dumas  <pertusus@free.fr>

	* tp/Makefile.am (dist_converters_DATA, test_files),
	tp/tests/formatting/Makefile.am, tp/tests/indices/Makefile.am: add
	new files.

	* tp/Texinfo/Convert/LaTeX.pm (_convert): use basename for image file
	and not full path.  The same as in other converters.  As a side effect
	helps to pass make distcheck.

2021-08-31  Patrice Dumas  <pertusus@free.fr>

	* tp/Makefile.am (dist_modules_DATA): add Texinfo/Translations.pm.

2021-08-31  Patrice Dumas  <pertusus@free.fr>

	move gdt() and string translation related code from
	tp/Texinfo/Report.pm to newly created tp/Texinfo/Translations.pm.

2021-08-31  Patrice Dumas  <pertusus@free.fr>

	* tp/texi2any.pl: use separate opened files informations
	for each of the files opened in texi2any.pl and add to
	the opened files list.

2021-08-31  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Common.pm (open_out, output_files_open_out)

	tp/init/chm.pm, tp/texi2any.pl:
	move the opened output file registration API completely to
	Texinfo::Common, renaming open_out() as output_files_open_out()
	and moving converter_unclosed_files(), register_close_file()
	converter_opened_files() from Convert::Converter to 
	Texinfo::Common renaming as output_files_unclosed_files(),
	output_files_register_closed() and output_files_opened_files().
	Pass a hash reference, initialized in Convert::Converter::converter
	to the API functions rather than a full converter.  Access 
	this hash reference through output_files_information() defined in
	Convert::Converter.

2021-08-31  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/Structuring.pm (sectioning_structure, nodes_tree),
	tp/Texinfo/Convert/Converter.pm (%all_converters_defaults)
	(converter), Pod-Simple-Texinfo/pod2texi.pl, texi2any.pl:
	Do not set 'structring' keys in Texinfo::Structuring
	sectioning_structure() and nodes_tree(), return the
	informations that are set in the caller.  The 'structuring'
	is not associated with parser anymore, but setup in the
	Texinfo::Structuring function callers.

	tp/Texinfo/XS/parsetexi/Parsetexi.pm (parser, _get_errors)
	(registered_errors), texi2any.pl: do not initialize parsers
	as Texinfo::Report objects, instead create a new Texinfo::Report
	object in Texinfo::Report::new, and pass it from the parsers
	using registered_errors().

	* tp/Texinfo/XS/parsetexi/Parsetexi.pm (@ISA): do not inherit
	DynaLoader.

2021-08-31  Patrice Dumas  <pertusus@free.fr>

	* tp/Texinfo/XSLoader.pm (init): pass warnings and die if

	* js/info.js (updater.navigate): Relative movement without node links.
	For example if the current item is a @subsection without a @node,
	requesting the 'next' item can't use the Next link as there is none.
	Instead, use the nesting in the sidebar ToC.

	Do not output the element footer if there is more than one node
	in the output file, using the 'elements_in_file_count' hash.

	These changes lead to a few changes as to whether a rule
	is output at the end of a file but the output appeared
	acceptable in the cases I checked.

	Per Bothner reported that the footer would
	be relative to the last node output in the file for
	--split=section, while it would make more sense to have this
	relative to the first node output in the file.  As this is
	not possible to do just now, just omit it.

	* tp/Texinfo/XS/xspara.c (xspara_add_text): Do not continue the loop

	Hilaire Fernandes reported the case of a broken macro when a comma
	separating arguments was at the end of a line.  This led the following
	newline to be included in the macro argument.

	This change stops whitespace being trimmed from the end of
	macro arguments, so only leading whitespace is trimmed, as
	is documented and is the case with texi2any's macro handling.

	* tp/Texinfo/Convert/HTML.pm (_convert_def_line_type):
	Split the conversion of the category away from the rest of
	the def line.  Add comments to label the different cases.

	This has a slight change to the output for @deffn with
	a completely empty argument, as this leads to the
	category being undefined.  It also changes a test
	result due to a translation for "{category}: " being missing
	(in French, this should come out as "{category}@ : ").

	This is preparation for allowing changing the formatting of
	the category with CSS, for example to float it to the right
	of the page.  Suggestion from Per Bother.

2020-10-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Do not set expanded_formats via parser.

	* tp/Texinfo/Convert/Converter.pm (converter): Do not copy
	'expanded_formats' from parser object to converter object.
	* tp/texi2any.pl: Copy 'expanded_formats' from parser object
	to converter object.

2020-10-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Do not set include_directories via parser.

	* tp/Texinfo/Convert/Converter.pm (converter): Do not copy
	'include_directories' from parser object to converter object.

	* tp/texi2any.pl: Add include directories to parser options
	and converter options separately.
	* tp/t/test_utils.pl: Set 'include_directories' in converter
	options explicitly.

	This should make it clearer where the 'include_directories'
	setting comes from.  Ideally the parser object should be used
	to access the results of parsing only, not to access parser
	settings.

2020-10-28  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/parsetexi/Parsetexi.pm (parser):
	Add a comment about copying the conf to the parser object.

2020-10-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Only call do_index_keys with converter object.

	* tp/t/test_utils.pl, tp/t/test_sort.t:
	Call Texinfo::Structuring::sort_indices with converter object
	rather than parser object.
	* tp/Texinfo/Convert/Text.pm: use Texinfo::Convert::Converter.
	* tp/Texinfo/Structuring.pm (do_index_keys): Update comment.

	This means that index sorting errors disappear from
	$result_errors, but they are still present in the converter
	errors.

2020-10-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Provide accesskey in section TOC.

	* tp/Texinfo/Convert/HTML.pm: Output accesskey attribute on <a>

	Fix messages. Do not warn if up node is an external node and inconsistent with menu

	* tp/Texinfo/Structuring.pm (nodes_tree): do not check for 
	node up / menu up mismatch if node up is an external node.
	* tp/Texinfo/Convert/HTML.pm (_element_direction): accept section
	type for TOP_NODE_UP_URL Up.


2020-10-27  Patrice Dumas  <pertusus@free.fr>

	Do not warn if external node in menu is not consistent with sections

	* tp/Texinfo/Structuring.pm (nodes_tree): do not warn if a menu entry
	referring to an external node is not consistent with sectioning.

2020-10-26  Patrice Dumas  <pertusus@free.fr>

	use httex instead of httexi for @math in default case

	* tp/init/tex4ht.pm ($STYLE_MATH): set to tex.

2020-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	@math, @displaymath documentation

	* doc/texinfo.texi (Inserting Subscripts and Superscripts):

	Comment out explanation of @\.  Explain that using any Texinfo
	commands inside math is not ideal.

2020-10-25  Patrice Dumas  <pertusus@free.fr>

	handle @displaymath with tex4ht and latex2html

	* tp/init/latex2html.pm (l2h_process, l2h_to_latex), 
	tp/init/tex4ht.pm ($tex4ht_command_displaymath, tex4ht_prepare):
	handle @displaymath.
	* tp/tests/coverage_macro.texi: use plain TeX math code in 
	@displaymath.
	* tp/tests/tex_html/tex.texi: add a @displaymath.

2020-10-25  Patrice Dumas  <pertusus@free.fr>

	add a @sup in @math{} in tex tests

	* tp/tests/tex_html/tex.texi: add @math{} with @sup{}
	to test.

2020-10-25  Patrice Dumas  <pertusus@free.fr>

	regenerate tex4ht/latex2html tests

	Note that tex must be changed to etex in httex and httexi to
	generate those tests results with recent tex4ht.

2020-10-25  Patrice Dumas  <pertusus@free.fr>

	@displaymath keep strings as is and add to coverage tests

	* tp/Texinfo/Convert/HTML.pm (_convert): increment 'math' context
	for @displaymath.
	* tp/Texinfo/Convert/Text.p (_convert): set code option for 
	Texinfo::Common::block_commands raw.
	* tp/t/02coverage.t, tp/tests/coverage_macro.texi, 
	tp/tests/*/res_parser/*: add @displaymath in coverage tests.

2020-10-25  Patrice Dumas  <pertusus@free.fr>

	Add a tree transformation to add missing menus

	* tp/Texinfo/Transformations.pm
	(_get_non_automatic_nodes_with_sections, complete_tree_nodes_menus,
	complete_tree_nodes_missing_menu, _prepend_new_menu_in_node_section), 
	doc/texinfo.texi (Other Customization Variables), texi2any.pl,
	tp/t/automatic_menus.t: add complete_tree_nodes_missing_menu
	transformation.  Add systematically the optional $use_sections
	argument to add a menu entry name using the section name to the 
	functions that can make use of that argument.
	* tp/Texinfo/Convert/Plaintext.pm (_convert), tp/Texinfo/Structuring.pm
	(node_menu_of_node): rename node_menu_of_node() as
	new_complete_node_menu().
	* tp/Texinfo/Structuring.pm (get_node_node_childs, new_complete_node_menu),
	tp/Texinfo/Transformations.pm (complete_node_menu): add
	get_node_node_childs() in Structuring.pm based on code in
	Transformations.pm, and use that code in new_complete_node_menu().
	* tp/Texinfo/Structuring.pm (node_menu_of_node, section_menu_of_node): 
	remove, optional arguments of the functions should be used instead.

2020-10-24  Patrice Dumas  <pertusus@free.fr>

	minor changes in comments and documentation

2020-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	Re-add example.

	* doc/texinfo.texi

2020-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (HTML Customization Variables, Inserting Math):

2020-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl: Use tex4ht if HTML_MATH is set to 't4h'.

2020-10-24  Patrice Dumas  <pertusus@free.fr>

	do not mix tex4ht commands STDIN with main script STDIN

	* tp/init/tex4ht.pm (tex4ht_process_command): use open
	with "|-" input pipe to launch tex4ht commands to avoid mixing
	main script STDIN and tex4ht commands STDIN.  It is important
	because when tex fails it reads from STDIN and the input may 
	trigger diverse actions by tex.

2020-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	Reduce example indent for @bsixpaper.

	* doc/texinfo.tex (@bsixpaper): Set \lispnarrowing to 0.2in.

2020-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	@set dispenvsize small for @bsixpaper.
	
	* doc/texinfo.tex (@bsixpaper): Switch some block commands
	to display with a smaller font.
	(\verbatim): Respect '@set dispenvsize small'.

2020-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	Documentation of customization variables.
	
	* doc/texinfo.texi
	(HTML Customization Variables, Other Customization Variables):
	Move INDEX_ENTRY_COLON and MENU_ENTRY_COLON to HTML Customization
	Variables.  Remove commented-out IDX_SUMMARY.  Remove example
	referring to non-existent PLAINTEXINFO variable.  Remove
	USE_NODE_TARGET as it doesn't do anything in the current code.
	* tp/Texinfo/Common.pm (@variable_string_settables),
	* tp/Texinfo/Convert/HTML.pm (%defaults): Remove 'USE_NODE_TARGET'.
	* tp/t/init/t2h_singular.init: Remove commented-out code referring
	to IDX_SUMMARY.

2020-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%line_commands),
	* tp/Texinfo/XS/parsetexi/command_data.txt: Add 'bsixpaper'.

2020-10-22  Gavin Smith  <gavinsmith0123@gmail.com>

	empty @headitem

	* tp/Texinfo/XS/parsetexi/api.c (element_to_perl_hash):
	Always create a contents array for @headitem even if it is empty.
	* tp/t/21multitable.t (empty_headitem): New test.

2020-10-22  Gavin Smith  <gavinsmith0123@gmail.com>

	Only reference MathJax on those pages which require it.

	* tp/Texinfo/Convert/HTML.pm
	(%defaults): New value 'element_math' to keep track of
	whether @math or @displaymath has been seen in current file.
	(_convert_math_command, _convert_displaymath_command)
	(output): Set and reset 'element_math'.  Process body of
	file before the header to set 'element_math' correctly.
	(file_header_informations): Only reference MathJax scripts
	if 'element_math' is set.
	
	(%defaults): New value 'jslicenses_element' to keep track
	of whether scripts have actually been used in the current output
	file.

	if there were actually JS scripts referenced in the file.

	unknown conf value.

2020-10-21  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove ENABLE_ENCODING setting for parser

	* tp/Texinfo/Common.pm (%default_customization_values):
	Remove 'ENABLE_ENCODING'.  This was passed indirectly to
	Texinfo::Convert::Text by Texinfo::Parser, but Texinfo::Parser
	has not depended on Texinfo::Convert::Text since 2016-07-09.

	* tp/t/test_utils.pl, tp/t/test_sort.t:
	Set 'ENABLE_ENCODING' on parser object before sorting indices
	to maintain consistency  in test results.

2020-10-21  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove TEST setting for parser

	* tp/Texinfo/Common.pm (%default_customization_values):
	Remove 'TEST'.
	* tp/Texinfo/ParserNonXS.pm (parse_texi_text, parse_texi_file)
	(parse_texi_line, _end_line):
	Remove code referring to the TEST setting.  This means that
	the 'input_directory' value is always set and all leading
	directory components will be removed from the input file name
	in messages.
	* tp/Texinfo/Convert/HTML.pm (_load_htmlxref_files): Make
	adding the input directory to the search path for htmlxref.cnf
	conditional on TEST.

2020-10-21  Gavin Smith  <gavinsmith0123@gmail.com>

	nodes_tree conditions

	* tp/Texinfo/Structuring.pm (nodes_tree):
	Remove conditions about external manuals in node up pointer.
	These conditions appeared to be ineffective due to a different
	check for menus on the up node preventing execution of
	a block of code.  Combine other conditions.  No functional
	changes intended.

2020-10-21  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Structuring.pm (nodes_tree): Warn about multiple
	@menu's regardless of value of SHOW_MENU.  Edit comments.
	Combine conditions (with no functional changes intended).

2020-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/tests/run_parser_all.sh: Don't pass -c SHOW_MENU=1
	to texi2any.

2020-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	SHOW_MENU=1 for TEXI2HTML=1.

	Set SHOW_MENU to 1.

2020-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	Set MENU_ENTRY_COLON back to :.
	
	* tp/Texinfo/Convert/HTML.pm (%defaults):
	Change 'MENU_ENTRY_COLON' back from '' to ':'.

	If somebody specifies '-c SHOW_MENU=1', they probably
	want something that looks more like the Info output.
	':' was the default setting until 2019-02-10.

2020-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	Don't add menus in HTML.pm.
	
	* tp/Texinfo/Convert/HTML.pm (_convert): Remove code to add a menu
	to a node where there wasn't one.

	Since SHOW_MENU now has the value section-toc by default,
	a menu is not necessary in a node for inferior nodes to be
	accessible.  If adding menus is wanted as a feature for HTML,
	this may be better done in non-format-specific code (e.g. with
	TREE_TRANSFORMATIONS).

2020-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	Warning only for menu missing node.

	* tp/Texinfo/Structuring.pm (nodes_tree): Use a warning instead
	of an error for the message, "node `%s' lacks menu item for
	`%s' despite being its Up target".

2020-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	No automatic menu if node has explicit pointers.

	* tp/Texinfo/Convert/Plaintext.pm (_convert)
	<sectioning commands>:
	Check if extra arguments were given to @node, and if they
	were, do not generate a menu if one was missing.

2020-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/htmlxref.cnf (tar): Fix.

2020-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	class="texi-manual"

	* tp/Texinfo/Convert/HTML.pm
	(_convert_xref_commands): Set class="texi-manual" on links
	to other Texinfo manuals.

2020-10-18  Gavin Smith  <gavinsmith0123@gmail.com>

	Manual revisions.

	* doc/texinfo.texi: Docbook -> DocBook throughout.

	(Writing a Node): Take out material about menus and detailed
	menus.
	(Master Menu Parts, Top Node): Move material about menus here.
	Use consistent terminology re "master menu" and "detailed menu".

	(\docindwrite): Likewise, for \doindwrite.
	(\splitindexentry): Check whether we are in a code index and add 
	\code if we are.
	(\docodeindex): Use \docind rather than \doind and wrapping 
	argument in \code.

	This allows @subentry and @sortas to work correctly.  Reports 
	from Werner Lemberg (June 2020) and Akim Demaille (November 
	2019).

2020-06-25  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix @verbatiminclude.

	* doc/texinfo.tex (\doverbatiminclude): Call \starttabbox before
	\input-ing the file, and do \egroup afterwards.  Otherwise the 
	catcode changes from \setupverbatim are cancelled at the end of 
	the first line with the \egroup from \par.

	Report from Akira Kakuto.

2020-05-20  Gavin Smith  <gavinsmith0123@gmail.com>

	(\bye): Call it.
	(\pagecount, \romancount, \arabiccount): New counts.
	(\advancepageno) [PDF]: Increment \pagecount.
	(\headings, \startcontents, \contents, \shortcontents):
	Set \romancount, \arabiccount appropriately.

	This means that the page numbers displayed in some PDF readers 
	can actually match the numbers printed on the pages.


2020-05-14  Gavin Smith  <gavinsmith0123@gmail.com>

	Input encoding error.

	* tp/Texinfo/ParserNonXS.pm (_open_in): Use ':encoding(utf-8)'
	instead of 'utf-8'.  Hopefully this makes encoding errors 
	non-fatal for Latin-1 files that aren't marked as such.  The 
	output would be mostly OK if only a few non-ASCII characters are 
	used.

2020-05-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/session.c (mouse_event_handler): Clear echo area.

2020-05-14  Gavin Smith  <gavinsmith0123@gmail.com>

	pre.smalldisplay CSS which isn't output anymore.

2020-05-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi: Revise some index entries and use @subentry.

2020-05-14  Gavin Smith  <gavinsmith0123@gmail.com>

	No title in headings in TOC with '@headings double'.

	* doc/texinfo.tex (\startcontents): Define @thistitle to be 
	empty.

2020-05-14  Gavin Smith  <gavinsmith0123@gmail.com>

	'@setchapternewpage off' headings.

	* doc/texinfo.tex (\CHAPPAGoff): Redefine \HEADINGSon as is done 
	for \CHAPPAGon and \CHAPPAGodd.
	(\HEADINGSsinglechapoff): The new definition.  Chapter pages 
	have the same headings as other pages.

2020-05-13  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove unused macro.

	* doc\texinfo.tex (\pagealignmacro): Remove macro.  It was not 
	used except in \bye.
	(\bye): Use \chappager instead of \pagealignmacro.  Presumably 
	we do not need an extra blank page at the very end of the 
	document if "@setchapternewpage odd" to make sure that we end on 
	an even page.
	(\startcontents): Remove a comment.  The comment credited
	Torbjorn Granlund <tege@matematik.su.se> for the 
	\contentsalignmacro, presumably added 1996-08-03.

2020-05-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi: Remove commented out "@set smallbook".

	* doc/texinfo.tex (\checkchapterpage): Set a new conditional,
	\ifchapterpage.
	(\evenchapheadline, \oddchapheadline): Add.
	(\headline): Use \ifchapterpage to possibly use 
	\evenchapheadline or \oddchapheadline.
	(\evenheadline, \oddheadline): Also set \evenchapheadline and 
	\oddchapheadline.
	(\HEADINGSdouble, \HEADINGSsingle): Call \HEADINGSdoublex and
	\HEADINGSsinglex.
	(\HEADINGSdoublex, \HEADINGSsinglex): Set \evenchapheadline and 
	\oddchapheadline omitting \thistitle and \thischapter.

2020-05-10  Gavin Smith  <gavinsmith0123@gmail.com>

	node into "Headings Introduced".

2020-05-10  Gavin Smith  <gavinsmith0123@gmail.com>

	Reorganise manual.

	* doc/texinfo.texi (Printed Books):
	(Obtaining TeX): Merge into "Use TeX" node.
	(Printed Books): Refer to "Hardcopy" node.  Edit to remove 
	repetition.  Remove material on the implementation of TeX.  Move 
	material on paper size to "Hardcopy" node.

2020-05-10  Gavin Smith  <gavinsmith0123@gmail.com>

	Reorganise manual.

	* doc/texinfo.texi
	(Formatting and Printing Hardcopy, Global Document Commands):
	Move sections "@smallbook", "A4 Paper", "@pagesizes", 
	"Magnification" to "Global Document Commands" appendix.

2020-05-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (@settitle): Do not refer to 
	@documentdescription.

2020-05-10  Gavin Smith  <gavinsmith0123@gmail.com>

	Reorganise manual.

	* doc/texinfo.texi (Catching Mistakes): Move this appendix to be 
	after "Using Texinfo Mode", with which it is more thematically 
	linked.

2020-05-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (@documentdescription): Move section under
	"Generating HTML" chapter.

2020-05-08  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Global Document Commands): Relegate to 
	appendix.

2020-05-08  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\indexnofonts):
	Give many commands a definition that removes the {} after use.  
	Sebastian Urban reported that @TeX{} appeared as "TeX{}" in a 
	PDF outline rather than "TeX".

2020-05-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Chapter numbers in PDF outlines.

	* doc/texinfo.tex (\pdfmakeoutlines) [pdftex, XeTeX]:
	Add chapter numbers in the PDF outline for chapters and 
	appendices only.  Suggestion from Sebastian Urban.

2020-05-06  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo-tex-test.texi (Environments, @verbatim): New 
	section.

2020-05-06  Gavin Smith  <gavinsmith0123@gmail.com>

	Fixed-width pounds sign.

	* doc/texinfo.tex (\pounds): Use \ecfont glyph for fixed-width 
	British pound sign.
	(\quotedblleft, \quotedblright): Use \ifmonospace instead of 
	\curfontstyle.

2020-05-06  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix braced group at start of @verbatim line.

	* doc/texinfo.tex (\setupverbatim):  Do not call \starttabbox 
	with \everypar.  Call \starttabbox at end of \par, and do not 
	call \leavevmode at start of \par.
	(\doverbatim): Call \starttabbox before processing contents of 
	@verbatim block.  Close a group at the end with \egroup.
	(\starttabbox): No need for \global in assignment.
	(\tabexpand): Call \leavevmode before adding box.

	If a character such as Ð at the start of a line expanded to a
	braced group (like {\ecfont \char"D0}), then \everypar would not 
	insert an opening brace until after the first opening brace, 
	leading the closing brace to close \verbbox prematurely.  The 
	single character in the box would be printed at the end of the 
	line.

2020-05-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Fixed-width directed double quotation marks.

	* doc/texinfo.tex (\quotedblleft, quotedblright): If we
	are in a fixed-width font, then use glyphs from European
	Computer Modern.  Sebastian Urban reported that “ and ”
	were output incorrectly.

2020-05-02  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix blank heading on last page of a chapter.

	(\checkchapterpage): Use \gettopheadingmarks or 
	\getbottomheadingmarks to determine the current chapter name.  
	\firstmark was wrong for this as it could give the wrong value 
	on the last page of a chapter.  Inconsistent output reported by
	Sebastian Urban.

2020-05-01  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo-tex-test.texi (Test of @*footing): Add.

2020-05-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Simplify output routine.

	* doc/texinfo.tex (\onepageout, \checkchapterpage):
	Split code to check if we are on a chapter page into a new 
	macro.
	* doc/texinfo-tex-test.texi (Test of @*heading): New section.

2020-04-23  Masamichi Hosoda <trueroad@trueroad.jp>

	* doc/txi-ja.tex: Remove \XeTeXgenerateactualtext=1 for XeTeX 0.99999+
	XeTeX 0.99999+ doesn't need this workaround.

2020-04-22  Masamichi Hosoda <trueroad@trueroad.jp>

	* doc/txi-ja.tex: Change default Japanese font to haranoaji.
	From TeX Live 2020, Japanese default font has become HaranoAji.

2020-04-14  Vincent Lefevre <vincent@vinc17.net>  (tiny change)

	Fix closing tag for footnotes heading.

	* tp/Texinfo/Convert/HTML.pm (_convert_footnote_command): 
	Correct closing tag from </h3> to </h5>.  Report from Kazuhiro

	would switch between the two elements, instead of following the 
	link.

	* tp/Texinfo/XS/parsetexi/macro.c (handle_macro): For a macro 
	taking a single argument, if the rest of the line is empty, 
	leave the newline on the line.  Otherwise, a command on the next 
	line would not be recognized as occurring at the beginning of 
	the line.  This led to errors with as.texi from binutils, 
	reported by Hans-Bernhard Bröker.

	* tp/t/60macro.t (include_after_empty_line_arg): New test.

2019-10-03  Gavin Smith  <gavinsmith0123@gmail.com>

	when my locale was en_GB.utf8 due to some translation files 
	provided by the "language-pack-en-base" package of Linux Mint 
	("recognized" was changed to "recognised").

2019-10-03  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix XS module loading.

	* tp/Texinfo/XSLoader.pm (init): Remove code looking for a Perl 
	file in Perl's search path based on the package name of the 
	module.  This does not correspond to a file and will be the same
	package name for XS and non-XS modules.  Remove 'standalone' and 
	'libtool' options for TEXINFO_XS variable.

	* tp/Texinfo/MiscXS.pm, tp/Texinfo/XS/MiscXS.xs: Use

	Fix XS fallback.

	rely on the loaded module using the correct package name in the 
	first place.

2019-10-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Attempt to fix fallback to pure Perl Texinfo::Parser.

	* tp/Texinfo/ModulePath.pm.in: Remove hook from @INC to load the 
	right version of Texinfo::Parser.
	* tp/Texinfo/XSLoader.pm: Add argument for an extra Perl file
	to be loaded in addition to the XS module.
	* tp/Texinfo/Parser.pm: Load XS or pure Perl module by
	calling Texinfo:XSLoader::init.  This is the same approach as 
	for Texinfo::Convert::Paragraph.  Load 
	tp/Texinfo/XS/parsetexi/Parsetexi.pm only after the XS 
	module has been successfully loaded.

	* tp/Texinfo/XS/parsetexi/Parsetexi.pm: Remove call to 
	Texinfo:XSLoader::init.

	* tp/Texinfo/XS/parsetexi/api.c (find_locales_dir): Don't use

	needed.  Report from Vincent Lefevre.

	case.

	But some old code doesn't know that Lua supports floating point numbers.
    
	This patch avoids some unexpected floating point numbers in Lua 
	code.

	* doc/txi-ja.tex: Update LuaTeX hack
    
	"comment" command is now unified to "c" command.

	* tp/Texinfo/Convert/Plaintext.pm (_convert) <menu_entry_node>:

	only strip of ".info".  Ludovico Courtès reported that 
	extensions were being used to distinguish translations of 
	manuals into other languages.

2019-04-28  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/Makefile.am
	(XSParagraph_la_LDFLAGS, Parsetexi_la_LDFLAGS):
	Put $(LTLIBINTL) and $(LTLIBICONV) in here.  Remove $(TERMLIBS) 
	which was not used.

	Attempt to fix building under Cygwin, which Hans-Bernhard Bröker 
	reported was broken.

2019-04-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Set TEXI2DVI in Makefile.

	* doc/Makefile.am: Set TEXI2DVI to use the texi2dvi in the 
	Texinfo sources rather than an installed one.

2019-04-27  Gavin Smith  <gavinsmith0123@gmail.com>

	Ignore spaces before @seeentry, @seealso and @sortas.

	* tp/Texinfo/ParserNonXS.pm (_parse_texi): Split off an ignored 
	spaces element if one of these commands is seen.
	* tp/Texinfo/XS/parsetexi/parser.c 
	(isolate_last_space_menu_entry_node, isolate_trailing_space):
	Rename and add a parameter.
	(process_remaining_on_line): After these commands are seen, call 
	isolate_trailing_space.

	* tp/t/09indices.t (subentry_and_sortas): New test.

	This allows these commands to occur at the end of index commands 
	without trailing spaces being present in the output.

2019-04-27  Gavin Smith  <gavinsmith0123@gmail.com>

	"See also" index entries for DocBook output.

	* tp/Texinfo/Convert/DocBook.pm (_index_entry):
	Output <see> or <seealso> elements if @seeentry or @seealso 
	directives were given for the index entry.

2019-04-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/ParserNonXS.pm (_enter_index_entry),
	* tp/Texinfo/XS/parsetexi/indices.c (enter_index_entry),
	* tp/Texinfo/XS/parsetexi/api.c (build_single_index_data): 
	Always create index entry object but do not add it to array of 
	entries for the index if there was a @seeentry or @seealso.

2019-04-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/parsetexi/indices.c (enter_index_entry): Skip if 
	'seeentry' or 'seealso' was recorded.
	* tp/Texinfo/XS/parsetexi/separator.c (handle_close_brace):
	Record values of 'seeentry' and 'seealso' the same way as for 
	'sortas'.  Ignore spaces following these commands.
	* tp/Texinfo/XS/parsetexi/command_data.txt: Add 'seeentry', 
	'seealso'.  Remove comments referring to line numbers in Common.pm.

2019-04-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%in_index_commands, %brace_commands):
	Add 'seeentry', 'seealso'.  These are handled the same way as 
	'sortas'.
	* tp/Texinfo/ParserNonXS.pm (%command_ignore_space_after):
	Add 'seeentry', 'seealso'.
	(_parse_texi) <close brace>: Record values of 'seeentry' and 
	'seealso' in extra hash the same way as for 'sortas'.
	(_enter_index_entry): Skip the index entry if there is a 
	'seeentry' or 'seealso' directive.
	* tp/Texinfo/Convert/Plaintext.pm (_convert): Do not warn about 
	unhandled commands if a 'seeentry' or 'seealso' directive is 
	present.

	* tp/t/09indices.t (seeentry): Add test.

2019-04-21  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove TOP_NODE_FILE.

	* doc/texinfo.texi (HTML Customization Variables): Remove 
	TOP_NODE_FILE.
	* tp/Texinfo/Common.pm (@variable_string_settables):
	Remove TOP_NODE_FILE.
	* tp/Texinfo/Convert/Converter.pm (_top_node_filename):
	Do not look at TOP_NODE_FILE.
	* tp/Texinfo/Convert/HTML.pm (%defaults): Use TOP_FILE instead 
	of TOP_NODE_FILE.
	(_set_variables_texi2html): Do not override value of TOP_FILE to 
	an empty string.
	* tp/init/chm.pm: Do not try to set TOP_NODE_FILE.

2019-04-03  Patrice Dumas  <pertusus@free.fr>

	Use EXTENSION instead of hardcoding html and add extension to TOP_NODE_FILE_TARGET

	* tp/Texinfo/Convert/Converter.pm (_top_node_filename),
	tp/Texinfo/Convert/HTML.pm (_set_root_commands_targets_node_files):
	use EXTENSION instead of .html.
	* tp/Texinfo/Convert/HTML.pm (%defaults, _external_node_href),
	doc/texinfo.texi (TOP_NODE_FILE_TARGET): default is now index.html.
	* tp/Texinfo/Convert/HTML.pm (_external_node_href): use 
	$external_file_extension instead of $extension to make clear that
	it is not the same as EXTENSION.
	* tp/t/init/t2h_singular.init (t2h_node_file_name): add that 
	function to replace .htm with .html for node files.
	* tp/tests/tex_html/list-of-tests: update to match SHORTEXTN 
	removal.

2019-04-12  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove some customization variables.

	* tp/texi2any.pl (HTML Customization Variables):
	Remove NODE_FILE_EXTENSION, SHORTEXTN.
	(Other Customization Variables): Remove NODE_FILENAMES.  Remove 
	mention of INPUT_ENCODING_NAME
	* NEWS: Mention removal.

2019-04-12  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove NODE_FILE_EXTENSION.

	* tp/Texinfo/Convert/HTML.pm (%defaults):
	(_set_root_commands_targets_node_files, _set_pages_files)
	(_external_node_href, output),
	* tp/Texinfo/Convert/Converter.pm (_set_pages_files, output)
	(_top_node_filename)

	Do not set or refer to NODE_FILE_EXTENSION.  The extension for 
	html files will always be '.html'.  Remove some commented-out 
	code.

2019-04-12  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove SHORTEXTN.

	* tp/Texinfo/Convert/HTML.pm (converter_initialize):
	Do not check SHORTEXTN customization variable.

2019-04-12  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove NODE_FILENAMES.

	* tp/Texinfo/Convert/HTML.pm (output, %defaults, _set_pages_files),
	* tp/Texinfo/Convert/Converter.pm (output, _top_node_filename)
	(_set_pages_files): Do not set or refer to NODE_FILENAMES.

	* tp/Texinfo/Convert/HTML.pm (_set_pages_files),
	* tp/Texinfo/Convert/Converter.pm (_set_pages_files):
	Remove code for naming output files with a number suffix (this 
	was the old texi2html behaviour).

2019-04-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\defsl): Declare with OT1 encoding instead of 
	OT1TT to avoid pdftex warning about conflicting CMap's.
	
2019-04-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Preparing for TeX):  Clearer wording
	about where TeX finds input files.  Report from Alan Mackenzie.  
	Update link to texinfo.tex.  Do not discuss how to set 
	environment variables in csh.

2019-04-11         Arnold D. Robbins     <arnold@skeeve.com>

	* doc/texinfo.texi: Update chapter on Indexing to cover new
	@seeentry, @seealso and @subentry commands. General smaller
	revisions to that chapter.

2019-04-08  Gavin Smith  <gavinsmith0123@gmail.com>

	Make texi2dvi --tidy more reliable.

	* util/texi2dvi (xref_files_save) [--tidy]: Check for auxiliary 
	files in the same directory as the input file, and remove them.
	(cd_dir): Possibly make $in_dir absolute.

	* NEWS: Mention texi2dvi changes.


2019-04-08  Gavin Smith  <gavinsmith0123@gmail.com>

	Do not change directory variables when changing directory.

	* util/texi2dvi (cd_dir, cd_orig): Do not change variables 
	containing pathnames.  Store a prefix to use with these 
	variables in $rel.  If either the new directory or in_input is 
	absolute, change all the pathname variables to be absolute.

	(xref_files_save, xref_files_changed): Prefix $work_bak with 
	$rel.
	(run_tex, run_hevea): Prefix $in_input with $rel.

	No functional changes intended.  The code to add and remove the 
	prefix from all of the variables had tricky quoting.  $rel is 
	only needed in a small number of places in functions called from 
	run_tex_suite.

2019-04-08  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/texi2dvi (make_openout_test): Call make_tex_cmd before 
	cd_dir.  This means that no calls to ensure_dir are called 
	between cd_dir and cd_orig.

2019-04-08  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/texi2dvi (run_tex): Remove use of make_tex_cmd.  I could 
	find nothing in make_tex_cmd that would change the result 
	between uses of run_tex.
	(run_tex_suite): Move use of make_tex_cmd here.

2019-04-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (HTML Customization Variables): Remove text 
	"For HTML" from the description of each variable, as it is clear 
	that these variables are all for HTML.

2019-04-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (latex2html Customization Variables): New 
	node, split from 'HTML Customization Variables'.

2019-04-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove @math and @tex as 'global commands.'

	* tp/Texinfo/ParserNonXS.pm (%global_multiple_commands),
	* tp/Texinfo/XS/parsetexi/api.c (build_global_info2),
	* tp/Texinfo/XS/parsetexi/parser.c (register_global_command),
	* tp/Texinfo/XS/parsetexi/parser.h (GLOBAL_INFO): Remove 'math' 
	and 'tex'.

	Reverts change on 2019-04-01.  Suggestion from Patrice.

2019-04-06  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\printindex): Give an error message with 
	\errmessage, instead of putting a message in the output 
	document, in order to give a hard failure in case an index file 
	has a backslash.  Suggestion from Karl.  Old index files will 
	still be upgraded by texi2dvi due to the previous change.

2019-04-06  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/texi2dvi: If TeX exits with a bad status, do not quit 
	immediately: check if the xref files have changed.  If they 
	have, the error might be corrected on subsequent runs.  This is 
	intended to help with moving index files to use @ as the escape 
	character instead of \.

2019-04-03  Patrice Dumas  <pertusus@free.fr>

	use tree in HTML handlers to collect @-command to be processed

	* tp/Texinfo/Convert/HTML.pm (run_stage_handlers): pass document
	tree root.
	* tp/Texinfo/Common.pm (collect_commands_in_tree): add.
	* tp/init/tex4ht.pm (tex4ht_prepare), tp/init/latex2html.pm (l2h_process):
	find the math and tex command using 
	Texinfo::Common::collect_commands_in_tree instead of relying
	on having those commands collected by the parser.

2019-04-03  Gavin Smith  <gavinsmith0123@gmail.com>

	Optionally use backslash as index escape character.

	* doc/texinfo.tex
	(\doindwrite): If the user gave '@set txiindexescapeisbackslash',
	then use \ as the escape character in the index file.
	(\splitindexentry): Use \string to output \indexlbrace etc.
	(\printindex): Under the same condition, read the sorted index 
	file with backslash as an escape character.  Expand the advice 
	on how to print the indices properly.

2019-04-03  Gavin Smith  <gavinsmith0123@gmail.com>

	Do not output literal backslash character in index files.

	* doc/texinfo.tex
	(\splitindexentry): In the sort key, use '{@indexbackslash }' 
	for a backslash, instead of a backslash character.
	(\initialglyphs): Recognize \indexbackslash.
	(\doindwrite): Output a backslash character as '@backslashchar {}'.
	(\definedummies): Define \backslashchar as a dummy.

	* doc/texinfo-tex-test.texi (Test of certain characters in index):
	Add more examples.

	This is intended to make it more reliable for either backslash 
	or at sign to be used as the escape character in index files, 
	for use with old versions of texi2dvi.  (This also allows 
	reading in old index files that used the \indexbackslash 
	sequence, although that is not very important.)

2019-04-03  Gavin Smith  <gavinsmith0123@gmail.com>

	* js/info.js (scan_toc): Use getElementById instead of 
	querySelector, as id's are unique.  From Mathieu.

2019-04-02  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\urefallowbreak): Reduce stretch from 1fil to 4em.

	This discourages breaking too early in the line.

2019-04-02  Gavin Smith  <gavinsmith0123@gmail.com>

	Support links between locally-installed manuals.

	* js/info.js (external_manual_url_p): New function.
	(fix_links): If a link to an external manual, open link in the 
	same browser tab.
	(on_click): No special handling of links to external manuals.

	This is intended to support links between locally-installed HTML 
	manuals.  For this to work, links to other manuals must begin 
	with "../", so htmlxref.cnf would need to be overridden.

2019-04-02  Patrice Dumas  <pertusus@free.fr>

	Avoid side effects in HTML formatting fonctions that can be overriden
	
	* tp/Texinfo/Convert/HTML.pm (_convert_heading_command,
	_convert_menu_command, _convert): move code with side effects (setting
	'seenmenus' and using 'seemenus' to add automatically a menu) out
	of formatting functions that can be overriden by a user to main
	converter function.
	* tests/tex_html: regenerate formatting_singular tests that overrides
	the menu formatting function.

2019-04-01  Patrice Dumas  <pertusus@free.fr>

	In _element_direction() output TOP_NODE_UP related infos even if element is not defined
	
	* tp/Texinfo/HTML.pl (_element_direction): output 
	TOP_NODE_UP related infos even if element is not defined.
	Explain in a comment when element is undef.

2019-04-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Add @math and @tex as 'global commands.'

	* tp/Texinfo/ParserNonXS.pm (%global_multiple_commands),
	* tp/Texinfo/XS/parsetexi/api.c (build_global_info2),
	* tp/Texinfo/XS/parsetexi/parser.c (register_global_command),
	* tp/Texinfo/XS/parsetexi/parser.h (GLOBAL_INFO): Add 'math' and 
	'tex'.
	* tp/init/latex2html.pm, tp/init/tex4ht.pm: Do not add values to 
	GLOBAL_COMMANDS.

	Patrice Dumas reported that tex4ht.pm and latex2html.pm were 
	broken since the GLOBAL_COMMANDS array was removed as a 
	customization value for init files (on 2018-10-13).

2019-04-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Make search-next and search-previous work for tree search.

	* info/session.c (info_search_next, info_search_previous):
	If there is an active tree search, carry on with it.  This means 
	that the '}' and '{' keys can be used to go through the results 
	from a tree search (instead of 'M-}' and 'M-{').
	(info_search_1): Disable any active tree search.
	* NEWS: Mention change.

2019-03-31  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove XS po directory.

	* tp/Texinfo/XS/po: Remove.
	* tp/Texinfo/XS/configure.ac (AC_CONFIG_FILES): Remove 
	po/Makefile.in.

	This keeps AM_GNU_GETTEXT in the XS subdirectory.  Apparently 
	AM_PO_SUBDIRS is also still used, even there is no po 
	subdirectory.

2019-03-31  Gavin Smith  <gavinsmith0123@gmail.com>

	Only use a single po directory.

	* po/POTFILES.in: List parsetexi input files.
	* po/Makevars (XGETTEXT_OPTIONS): Move options from
	tp/Texinfo/XS/po/Makevars.

2019-03-31  Gavin Smith  <gavinsmith0123@gmail.com>

	Find translation directory for parsetexi.

	* tp/Texinfo/XS/parsetexi/api.c (find_locales_dir): New 
	function.
	(init): Call it.
	* NEWS: Mention change.

2019-03-31  Gavin Smith  <gavinsmith0123@gmail.com>

	Pass on srcdir to XS modules.

	* tp/Texinfo/ModulePath.pm.in ($srcdir): New variable.
	(init) [uninstalled]: Set it.
	* tp/Texinfo/XSLoader.pm: Pass on $Texinfo::ModulePath::srcdir 
	to XS modules.
	* tp/Texinfo/XS/parsetexi/api.c (init): Save value of srcdir.

2019-03-31  Gavin Smith  <gavinsmith0123@gmail.com>

	Output message if file ended inside Top node.

	* doc/texinfo.tex (\omittopnode): Redefine @bye and put a 
	message in the output file to say the Top node was omitted.  
	This is most likely for short test files that consist only of a 
	Top node.

2019-03-31  Gavin Smith  <gavinsmith0123@gmail.com>

	* NEWS: Add some news items.

2019-03-31  Gavin Smith  <gavinsmith0123@gmail.com>

	Make texi2dvi --batch the default.

	* util/texi2dvi: (batch): Remove variable.
	(usage): Do not mention --batch.
	(make_tex_command): Unconditionally run in batch mode.
	(make_openout_test): Do not save and restore $batch.
	(input_file_name_decode): Do not set $batch for AUC-Tex input.
	(usage): Remove a comment about 'echo' compatibility.

2019-03-31  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Inserting Unicode): Include the Ĳ ligature 
	in the output.  Do not say that a UTF-8 encoding must be 
	explicitly requested.

2019-03-30  Gavin Smith  <gavinsmith0123@gmail.com>

	Module search path changes (no functional changes intended).

	* tp/texi2any.pl:
	Only check if one variable has been substituted by the Makefile 
	to create this file.  Do not set environment variables: only add 
	a directory to @INC so that Texinfo:ModulePath might be found.
	Pass an 'updirs' argument into Texinfo::ModulePath.
	* tp/Texinfo/ModulePath.pm.in (init): Change argument from 
	'uninstalled' to 'installed', so that the uninstalled case is 
	the default.  Place code for using uninstalled files and 
	checking environment variables inside a conditional so it is 
	clearer when this code is used.  Do not set any environment 
	variables: use them for input only.

2019-03-30  Gavin Smith  <gavinsmith0123@gmail.com>

	Introduce blank lines in test case.

	* tp/t/converter_tests.t ($at_commands_in_refs_text): Introduce 
	blank lines in input Texinfo to avoid problems with varying line 
	break decisions due to different wcwidth implementations.
	* tp/t/converters_tests.t (at_commands_in_refs): Do not skip.
	(at_commands_in_refs_utf8): Do not skip this one either, since 
	we are now counting combining accents in the XS code as having 
	width.

2019-03-30  Gavin Smith  <gavinsmith0123@gmail.com>

	Skip tests instead of marking them as expected failures.

	* tp/t/test_utils (test): If a test case is marked as 'todo', 
	always skip the test with 'skip' from Test::More, instead of 
	putting it inside a 'TODO' block.  Remove some commented-out 
	code.

2019-03-30  Gavin Smith  <gavinsmith0123@gmail.com>

	Skip a test.

	* tp/t/converters_tests.t (at_commands_in_refs): Skip plaintext
	output until we can get consistent results on Solaris 10 and 
	Solaris 11.

2019-03-30  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl: Do not print errors from conversions.

2019-03-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Use 'utf-8' instead of 'utf-8-strict' as name of encoding.

	* tp/Texinfo/Common.pm (%default_parser_state_configuration)
	(open_out, count_out): Use 'utf-8' instead of 'utf-8-strict' as 
	the name of the perl encoding.
	* tp/Texinfo/ParserNonXS.pm (_open_in): Check for 'utf-8' 
	instead of 'utf-8-strict'.  Add a missing closing parenthesis in 
	input filter declaration.
	* tp/Texinfo/XS/parsetexi/parser.c (wipe_global_info):
	Use 'utf-8' instead of 'utf-8-strict'.

	On perl v5.8.4, there was an error 'Cannot find encoding 
	"utf-8-strict"'.  (This version is used on the OpenCSW 
	buildfarm.)

2019-03-28         Arnold D. Robbins     <arnold@skeeve.com>

	* texinfo.tex: @see is now @seentry, per Gavin. Removed
	spurious definition of \putwordSee.

2019-03-27  Patrice Dumas  <pertusus@free.fr>

	Set Top node Up per format and not in Structuring.

	* tp/Texinfo/Common.pm, tp/Texinfo/Convert/Converter.pm: set 
	TOP_NODE_UP in converter defaults.
	* tp/Texinfo/Structuring.pm, tp/Texinfo/Convert/HTML.pm,
	tp/Texinfo/Convert/Info.pm, doc/texinfo.texi: do not set 
	the Top node Up in Structuring but in converters. Only use 
	TOP_NODE_UP and set an Up URL/name in HTML when TOP_NODE_UP_URL 
	is set and do not modify all the links of the TOP_NODE_UP, 
	only the Top node Up links.

2019-03-27  Patrice Dumas  <pertusus@free.fr>

	* tp/init/chm.pm, tp/init/latex2html.pm, tp/init/tex4ht.pm:
	use __() from Texinfo::Common

2019-03-27  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix test of XS modules.

	* tp/Texinfo/XS/TestXS.pm: Declare init function as having a 
	single argument, and return a true value.  Otherwise the test 
	for XS modules fails.  Report from Patrice Dumas.

2019-03-27  Gavin Smith  <gavinsmith0123@gmail.com>

	Small changes.

	* tp/Texinfo/XS/xspara.c (xspara_add_text): Add a comment.
	* tp/tests/sectioning/Makefile.am: Do not try to distribute a 
	removed file.
	* tp/Texinfo/XS/po/texinfo.pot: Untrack in git.

2019-03-27  Gavin Smith  <gavinsmith0123@gmail.com>

	Make test results consistent for older versions of perl.

	* tp/Texinfo/Convert/Plaintext.pm (@U): Check argument to @U 
	before attempting to output the character.  The check inside 
	eval doesn't work for old versions of perl.  Trim down some 
	comments.

2019-03-25  Gavin Smith  <gavinsmith0123@gmail.com>

	Make test results consistent between XS and non-XS modules.

	* tp/Texinfo/XS/xspara.c (xspara_add_text): Treat characters 
	with wcwidth 0 the same as those with wcwidth 1.  This is wrong, 
	but gives consistency for the test results.

2019-03-24         Arnold D. Robbins     <arnold@skeeve.com>

	@see in index entries (experimental).
	
	* doc/texinfo.tex
	(\see, \putwordSee): Add default definitions for reading 
	in a sorted index file.
	(\splitindexentry): Record value of any @see directive in 
	the index entry inside \pagenumbertext.  Make @see expansion 
	empty when getting the sort key.

2019-03-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/htmlxref.cnf: Update 'mit-scheme-imail'.  From
	Thérèse Godefroy.

2019-03-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/parsetexi/parser.c (wipe_global_info): Set 
	input_encoding_name as well as input_perl_encoding.

2019-03-24  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove INPUT_PERL_ENCODING and INPUT_ENCODING_NAME as 
	customization variables.

	* tp/Texinfo/Common.pm (%default_customization_values)
	(@variable_string_settables): Remove INPUT_PERL_ENCODING and 
	INPUT_ENCODING_NAME.
	* tp/Texinfo/Convert/Converter.pm (converter),
	* tp/Texinfo/XS/parsetexi/Parsetexi.pm (parse_texi_file),
	Remove code propagating INPUT_PERL_ENCODING and 
	INPUT_ENCODING_NAME.

	* tp/Texinfo/ParserNonXS.pm (%initialization_overrides):
	Remove 'INPUT_ENCODING_NAME'.

	* tp/Texinfo/ParserNonXS.pm (_open_in, _end_line, _parse_texi),
	* tp/Texinfo/Convert/Converter.pm (converter),
	* tp/Texinfo/Convert/IXIN.pm (output_ixin),
	* tp/Texinfo/Structuring.pm (do_index_keys):
	Do not use INPUT_PERL_ENCODING or INPUT_ENCODING_NAME: use the 
	'info' hash instead.

	* tp/Texinfo/Common.pm (_convert_text_options),
	* tp/Texinfo/Report.pm (gdt),
	* tp/texi2any.pl:
	Do not look use INPUT_ENCODING_NAME or INPUT_PERL_ENCODING.

	* doc/texinfo.texi (Other Customization Variables):
	Remove INPUT_PERL_ENCODING and INPUT_ENCODING_NAME.  Remove 
	@ifnottex block around Top node.

	This is an attempt at simplifying a complicated picture around 
	character encoding.  These customization variables had little 
	use as the encoding is given as @documentencoding in the input.


2019-03-24  Gavin Smith  <gavinsmith0123@gmail.com>

	Use UTF-8 more consistently in test suite.

	* tp/Texinfo/ParserNonXS.pm (parse_texi_file): Do not set
	'input_encoding_name' and 'input_perl_encoding' here.
	* tp/Texinfo/Common.pm (%default_parser_state_configuration):
	Set 'input_encoding_name' and 'input_perl_encoding' here.

2019-03-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Make UTF-8 default input encoding for parsetexi.

	* tp/Texinfo/XS/parsetexi/Parsetexi.pm (parse_texi_file):
	Propagate values of INPUT_PERL_ENCODING and INPUT_ENCODING_NAME.
	* tp/Texinfo/XS/parsetexi/api.c (reset_parser_except_conf):
	Call 'set_input_encoding' to use "utf-8" as the default.
	* tp/Texinfo/XS/parsetexi/parser.c (wipe_global_info): Set
	global_info.input_perl_encoding to "utf-8-strict".

	This replicates changes made on 2019-02-23 and 2019-02-26.

2019-03-23  Gavin Smith  <gavinsmith0123@gmail.com>

	@subentry in parsetexi.

	* tp/Texinfo/XS/parsetexi/command_data.txt: Add subentry.
	* tp/Texinfo/XS/parsetexi/handle_commands.c
	(handle_line_commands) <@subentry>: Add section.
	(handle_brace_commands) <@sortas>: Allow to occur inside @subentry.
	* tp/Texinfo/XS/parsetexi/parser.c (check_valid_nesting): Allow 
	@subentry to occur inside most commands.
	(process_remaining_on_line) <@-command>: Allow @subentry to 
	occur other than at the beginning of a line.
	* tp/Texinfo/XS/parsetexi/separator.c (handle_close_brace) 
	<@sortas>: Record sort key on @subentry element.

2019-03-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix sort key for undefined @value.

	* doc/texinfo.tex (\indexnofontsvalue): Place a % comment 
	character after the text for an undefined @value.
	If this comment character isn't present and the @value is 
	followed by a space, the rest of the index sort key will be 
	discarded inside @eatspaces called from @splitindexentry.  It 
	appears that @eatspaces does not cope with several spaces in a 
	row in its argument.

2019-03-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Add more tests of @value in index.

	* doc/texinfo-tex-test.texi (Test of auxiliary files):
	Add test of values in index entries containing underscores and 
	nested Texinfo commands.  Add test of a @value that changes.
	* doc/texinfo.tex (\expandablevalue): Remove obsolete comment.  
	@value in index entries is more reliable now that we use @ as 
	the escape character in index entries.

2019-03-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove apparently unused code.

	* doc/texinfo.tex (\begindoublecolumns): Remove code that is 
	supposed to account for the output routine in 
	\begindoublecolumns being called twice in a row.  It checks 
	whether \partialpage is void, but it appears that \partialpage 
	will always be void.  \doublecolumnout, \balancecolumns and 
	\pagesofar all clear \partialpage with \unvbox, which I believe 
	covers all the cases.  I was unable to get this code to run with 
	various tests.  Remove references to long-lost test files.  
	(Removed code introduced on Jan 14 16:53:43 1999 according to 
	ChangeLog entry.)

2019-03-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Ignore Top node a different way.

	(\omittopnode): Change implementation so as to work when the 
	next node is hidden inside an included file.
	(\nwnode, \up, \down): Remove these useless synonyms.

2019-03-22  Gavin Smith  <gavinsmith0123@gmail.com>

	Ignore Top node in texinfo.tex even without @ifnottex.

	* doc/texinfo.tex (\omittopnode): New macro.
	(\node): Call it.

2019-03-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\texinfoc): Remove.
	(\scanmacro): Use \comment instead of \texinfoc.  \comment has 
	the same meaning inside math mode as outside.
	(\argremovecomment): Don't bother about @texinfoc.

2019-03-18  Gavin Smith  <gavinsmith0123@gmail.com>

	Pass on to XS modules whether uninstalled files should be used.

	* tp/Texinfo/ModulePath.pm.in ($texinfo_uninstalled): New 
	variable.
	(init): Set it if passed the right argument.
	* tp/texi2any.pl: Pass on to Texinfo::ModulePath::init whether
	uninstalled files should be used.  Use the value of 
	$texinfo_uninstalled to decide where to look for locale files.
	Remove some commented-out code and move a variable declaration 
	into a smaller block.
	* tp/Texinfo/XSLoader.pm: Pass on 
	$Texinfo::ModulePath::texinfo_uninstalled to XS modules.

2019-03-17  Gavin Smith  <gavinsmith0123@gmail.com>

	Find translatable strings in parsetexi.

	* tp/Texinfo/XS/po/Makevars (XGETTEXT_OPTIONS): Use line_error 
	and similar functions to mark translatable strings.  (This 
	should maybe be done in the top-level po/Makevars instead.)
	* tp/Texinfo/XS/parsetexi/errors.c (line_error_internal):
	Pass message string to gettext function.
	* tp/Texinfo/XS/po/POTFILES.in: List files containing 
	translatable strings.

2019-03-17  Gavin Smith  <gavinsmith0123@gmail.com>

	Add gettext to XS modules.

	* tp/Texinfo/XS/parsetexi/Parsetexi.xs,
	* tp/Texinfo/XS/parsetexi/api.c (init):
	Add, to be called from Texinfo::XSLoader.  Initialize gettext.

	* tp/Texinfo/XS/parsetexi/api.c: Include libintl.h.

	* tp/Texinfo/XS/configure.ac: Add AM_GNU_GETTEXT([external]).
	* tp/Texinfo/XS/Makefile.am (AM_CPPFLAGS): Define DATADIR.

	* tp/Texinfo/XS: Run 'gettextize'.
	I do not know if '--po-dir=../../../po -f' should have been used 
	here - should we share the po directory with the top-level 
	project?
	* tp/Texinfo/XS: Run 'aclocal -I gnulib/m4'.
	* tp/Texinfo/XS/po/Makevars: Copy from Makevars.template.  I'm 
	not sure if this will be used.

	Changes made by gettextize:
	* tp/Texinfo/XS/Makefile.am (SUBDIRS): Add po.
	* tp/Texinfo/XS/configure.ac (AC_CONFIG_FILES): Add po/Makefile.in.

        * tp/Texinfo/XS/gnulib/m4/gettext.m4: New file, from gettext-0.19.8.
        * tp/Texinfo/XS/gnulib/m4/iconv.m4: Upgrade to gettext-0.19.8.
        * tp/Texinfo/XS/gnulib/m4/lib-ld.m4: Upgrade to gettext-0.19.8.
        * tp/Texinfo/XS/gnulib/m4/lib-link.m4: Upgrade to gettext-0.19.8.
        * tp/Texinfo/XS/gnulib/m4/lib-prefix.m4: Upgrade to gettext-0.19.8.
        * tp/Texinfo/XS/gnulib/m4/nls.m4: New file, from gettext-0.19.8.
        * tp/Texinfo/XS/gnulib/m4/po.m4: New file, from gettext-0.19.8.
        * tp/Texinfo/XS/gnulib/m4/progtest.m4: New file, from gettext-0.19.8.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	@seealso in index entries (experimental).
	
	* doc/texinfo.tex
	(\seealso, \putwordSeeAlso): Add default definitions for reading 
	in a sorted index file.
	(\splitindexentry): Record value of any @seealso directive in 
	the index entry inside \pagenumbertext.  Make @seealso expansion 
	empty when getting the sort key.
	(\doindwrite): If \pagenumbertext set, use its contents instead 
	of \folio in the page number field.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo-tex-test.texi (Index subentries): New section.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Combine pdftex and XeTeX conditionals.

	* doc/texinfo.tex (\ifpdforxetex): New conditional.  Use it in
	several places.  This removes some code duplication.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Support @tertiary in sorted index file.

	* doc/texinfo.tex (\indententry): New.
	(\secondary, \tertiary): Use it.
	(\entry): Fix case when there are no page numbers and no leaders 
	are being printed.  Indent code that is outputting inside a box.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\printindex): Fix detection of backslash in 
	sorted index file.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Make @subentry the same level as index command in tree.

	* tp/Texinfo/ParserNonXS.pm (_parse_texi) <@subentry>:
	Call _end_line to avoid @subentry becoming a child of an index 
	command or another @subentry command.

	This means that we convert back to Texinfo correctly without 
	misplacing spaces before the @subentry command.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove unused function.

	* tp/Texinfo/Convert/Converter.pm (_register_command_arg): Remove.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Test of @subentry.

	* tp/t/09indices.t (subentries): New test.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	@subentry in DocBook output.

	* tp/Texinfo/Convert/DocBook.pm (_index_entry):
	Possibly output index subentries inside <secondary> or 
	<tertiary> elements.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	@subentry in HTML output.

	* tp/Texinfo/Convert/Converter.pm (convert_index_subentries): New.
	* tp/Texinfo/Convert/HTML.pm (_convert_printindex_command): Use it.
	* tp/Texinfo/Convert/Plaintext.pm (_printindex_formatted): 
	Inline code from convert_line and call convert_index_subentries.

2019-03-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Start on supporting @subentry in parser and Info output.

	* tp/Texinfo/Common.pm (%line_commands): Add 'subentry'.
	* tp/Texinfo/ParserNonXS.pm
	(%in_full_text_commands): Include 'subentry' so that @subentry 
	can appear inside an index command.
	(%begin_line_commands): Allow @subentry to occur other than at 
	the beginning of a line.
	(_is_index_element): New.
	(_parse_texi): Use _is_index_element to check if we are in an 
	index command.
	(_parse_texi) <line commands>: Handle @subentry.  Check valid 
	nesting.  Keep track of how many @subentry's have been used.
	* tp/Texinfo/Convert/Plaintext.pm (_printindex_formatted): If 
	there are index subentries, add them to the end of the text of 
	the index entry, separated by commas.

	This represents index subentries as a line command at the end of 
	the index entry.  A second @subentry is nested inside the first.

2019-03-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/18itemize.t (table_in_itemize): New test.

2019-03-13  Gavin Smith  <gavinsmith0123@gmail.com>

	Examples of special characters in PDF destinations.

	* doc/texinfo-tex-test.texi
	(Test of characters in node names for PDF): New test.

2019-03-12  Gavin Smith  <gavinsmith0123@gmail.com>

	Only load lcircle10 if @cartouche is used.

	* doc/texinfo.tex (\cartouchefontdefs): New macro.  Put loading 
	lcircle10 font in here.
	(\cartouche): Use it.

	This is a similar approach to that used for @euro{}.

2019-03-11  Gavin Smith  <gavinsmith0123@gmail.com>

	Active backslash in \setupdatafile.

	* doc/texinfo.tex (\setupdatafile): Make backslash active rather 
	than other.  This means that a section title is printed 
	correctly with input like the following:

	   \input texinfo
	   @xrefautomaticsectiontitle on
	   
	   @node One
	   @chapter One
	   
	   One.  @xref{Two}.
	   
	   @node Two
	   @chapter Two \
	   
	   @bye
	
	Without this, the backslash typesets as quotation marks.  Delete 
	an old comment stating that catcode other is needed for \csname 
	to work in \xrdef.  Currently, \turnoffactive called in \xrdef
	gives backslash the needed definition.  In any case, backslashes 
	in node names appear to produce buggy PDF files in many cases.

	* doc/texinfo.tex (\setupdatafile): Remove out-of-date comment 
	about why we do not support ^^ notation in auxiliary files.

2019-03-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo-tex-test.texi (Test of index widow elimination):
	Comment out.
	(No page number in index): New section.

2019-03-10  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove code for preventing widowed index entries.

	* doc/texinfo.tex
	(\finishentry): Output the index entry directly to the current 
	vertical list instead of storing it in a box and then calling 
	\dotheinsertentrybox.
	(\insertentrybox, \dotheinsertentrybox)
	(\dotheinsertentryboxwithpenalty, \ourunvbox): Remove.
	(\entry): No redefinition of \domark.
	(\printindex): Do not redefine \dotheinsertentrybox.  Read file 
	with \input instead of line-by-line with \read.
	(\indexinputprocessing, \loopdo): Remove.

	This code added an awful lot of complexity for not much benefit.
	It is better to use the processes provided in TeX (\input and 
	\unvbox) where possible, instead of creating a separate version.

2019-03-10  Gavin Smith  <gavinsmith0123@gmail.com>

	Use <h5> for footnote labels.

	* tp/Texinfo/Convert/HTML.pm (_convert_footnote_command): Use 
	<h5> instead of <h3> for the numbered footnote labels.  
	Jean-Christophe Helary reported that the <h3> level being used 
	was greater than that for the main footnotes heading, which was 
	only <h4>.

2019-03-10  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix indentation of @table within @itemize.

	* tp/Texinfo/Convert/Plaintext.pm (ensure_end_of_line):
	Set 'counter' on top-most 'text_element_context' to zero.  This 
	makes a @table be indented correctly within an @itemize and also
	means an @item immediately following the @table is indented 
	properly.  Report from Alan Mackenzie.

2019-03-09  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove unused backslash macros.

	* doc/texinfo.tex (\rawbackslash): Remove.  It appears to be
	unnecessary as @t and @code work fine without it.
	(\t, \tclose): Do not call \rawbackslash.
	(\rawbackslashxx, \doublebackslash): Remove.

2019-03-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo-tex-test.texi (Index display): Use @ as the escape 
	character.
	(@,c in macro argument): @, doesn't work any more in macro 
	argument due to changing the catcode of @.

2019-03-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\macroargctxt, \macrolineargctxt): Set 
	catcode of @ to other.

2019-03-09  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove description of a bug fixed by the last change.

	* doc/texinfo-tex-test.texi: Remove description of why a Texinfo 
	command inside an @example inside a macro didn't work.  It works 
	now that @ is no longer an escape character when a macro body is 
	read.  This means that \scantokens no longer sees any control 
	sequences in the macro body and does not insert extra spaces.

2019-03-09  Gavin Smith  <gavinsmith0123@gmail.com>

	No catcode changes in \scanmacro.

	* doc/texinfo.tex (\scanmacro): Do not change catcode of @ or \.

2019-03-09  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix marginindex flag.

	(\doindwrite, \maybemarginindex): Move code to put index entry 
	in the margin to a new macro, and make it work again.

2019-03-09  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove \indexdummies.

	* doc/texinfo.tex (\indexdummies): Remove.
	(\doindwrite): Call \atdummies instead of \indexdummies and move 
	the special definitions of \{ and \} here.
	(\onepageout): Call \atdummies instead of \indexdummies.

2019-03-03  Gavin Smith  <gavinsmith0123@gmail.com>

	Use @ as escape character in index files.

	* doc/texinfo.tex
	(\indexdummies): Do not change \escapechar to backslash.
	Call \otherbackslash in order to keep backslash as it is.
	(\doindwrite, \indexnonalnumreappear):
	Do not call \useindexbackslash or change the definition of \@.
	(\indexbackslash, \useindexbackslash): Remove.
	(\splitindexentry): Convert @@ and @atchar{} to {@indexatchar}.
	texindex does not currently output given a sort key beginning 
	with @ as @initial{@@}, outputting @initial{@} instead.

	(\onepageout): Remove comment about backslash in index files.  
	Call \turnoffactive instead of \normalturnoffactive in order to 
	output backslash as itself in index files.

	(\printindex): Do not change catcode of \ or @.
	(\printindex, \initialglyphs): Move setting \indexlbrace and 
	\indexrbrace to \initialglyphs, and add \indexatchar too.  Do 
	not set \indexbackslash.

	(\atdummies): Comment changed so as no longer to imply that the 
	aux and toc files are the only auxiliary files using @.

	(\printindex): Cheeck first character of index file, and if it 
	is a backslash, skip reading the file.

	* doc/texinfo-tex-test.texi (Test of certain characters in index):
	New section.
	* util/texi2dvi (index_file_p): Check for a @entry in index 
	files as well as \entry.

2019-03-03  Gavin Smith  <gavinsmith0123@gmail.com>

	Reset output routine correctly.

	* doc/texinfo.tex (\defaultoutput): New token list, to contain
	default output routine.
	(\enddoublecolumns): Use it to correctly use \savetopmark in the 
	output routine after the output of an index is finished.
	* doc/texinfo-tex-test.texi: Remove @bye line ending file by 
	mistake.

2019-03-03  Gavin Smith  <gavinsmith0123@gmail.com>

	No stretch around breakable characters in URL's.

	* doc/texinfo.tex
	(\urefprestretchamount, \urefpoststretchamount): Remove.
	(\urefprestretch, \urefpoststretch): Remove.  Replace calls with
	\urefprebreak and \urefpostbreak.
	(\urefallowbreak): New macro, to allow a ragged right break 
	within a URL.

	* doc/texinfo-tex-test.texi (URL line breaking): New section.

	This could lead to too much space being inserted, for example 
	around the two slashes in "http://".  The ragged right break 
	prevents under-full or over-full boxes.  (bug-texinfo, July 2018.)

2019-03-03  Gavin Smith  <gavinsmith0123@gmail.com>

	Tidy up index writing.

	* doc/texinfo.tex (\dosubindwrite, \doindwrite): Rename.
	(\doind, \dosubind): Make \dosubind call \doind, not vice versa.  
	Move definition of \dosubind nearer where it is used.

	(\deffngeneral): Remove a comment.

2019-03-02  Gavin Smith  <gavinsmith0123@gmail.com>

	Implement index subentries in texinfo.tex.

	* doc/texinfo.tex (\splitindexentry): New macro.
	(\dosubindwrite): Call it to get the index text split up into 
	primary entry and possible secondary and further entries
	separated by @subentry, as well as the index sort key.  For one 
	subentry only, this is the same format as was output in the past 
	and recognized by the C implementation of texindex.

	This feature is experimental.

2019-03-02  Gavin Smith  <gavinsmith0123@gmail.com>

	Change how marks are preserved.

	* doc/texinfo.tex (\savemarks, \restoremarks): Remove.  No 
	longer propagate marks by running an output routine.  This could 
	lead to whatsits being thrown away in \restoremarks.
	(\savedtopmark, \savetopmark, \iftopmarksaved): New.  Save 
	\topmark only in \savedtopmark, a token list register.
	(\gettopheadingmarks, \getcolormarks, \onepageout)
	(\begindoublecolumns, \doublecolumnout):
	Use \savetopmark instead.
	
	The old behaviour made texinfo.tex less hackable, as simple 
	input like:

	  \input texinfo
	  
	  @cindex dddddd
	  @cindex fff
	  
	  @printindex cp
	  @bye

	could lead to an empty *.cp file, which was confusing, even if 
	this kind of problem would never occur in real documents.

2019-03-02  Gavin Smith  <gavinsmith0123@gmail.com>

	Add test material for headings and footings.

	* doc/texinfo-tex-test.texi (Headings and footings): New section.

2019-03-02  Gavin Smith  <gavinsmith0123@gmail.com>

	Rename \lastchapterdefs.

	* doc/texinfo.tex:
	(\lastchapterdefs, \currentchapterdefs)
	(\lastsectiondefs, \currentsectiondefs)
	(\lastcolordefs, \currentcolordefs)
	(\lastsection, \currentsection):
	Rename, as it is confusing to have both \lastchapterdefs and 
	\prevchapterdefs: both "last" and "previous" mean the same 
	thing.

2019-03-02  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix @everyheadingmarks top.

	* doc/texinfo.tex (\onepageout): Separate the code for setting 
	\headlinebox and \footlinebox.  Otherwise, the definitions for 
	the footline would overwrite those for the headline, rendering 
	'@everyheadingmarks top' ineffective.

2019-03-02  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\chapmacro): Remove obsolete comment about 
	\setcontentsaftertitlepage.

2019-02-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove obsolete and unused code.

	* doc/texinfo.tex (\cindexsub): Remove.  It has been in 
	texinfo.tex for a very long time but is not documented or 
	implemented in makeinfo.

2019-02-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Better support for @sortas at end of index entry.

	* doc/texinfo.tex (\dosubindwrite): Use \eatspaces to trim 
	leading and trailing spaces from the index entry.  This means a 
	@sortas command can occur at the end of the index entry with a 
	space before it, and the space will be removed when writing to 
	the index file.
	(\sortas): Expand to empty.
	(\dosubind): Do not set \toks0: use a \def instead to store the 
	index entry text.

2019-02-26  Gavin Smith  <gavinsmith0123@gmail.com>

	Use UTF-8 input and output by default for Info.

	* tp/Texinfo/ParserNonXS.pm (_open_in): New function.
	(parse_texi_file),
	(_end_line) <@include>: Use it.
	(parse_texi_file): Set the input encoding on $self->{'info'}.

	* tp/Texinfo/Convert/Unicode.pm (%extra_unicode_map): New hash,
	to contain a subset of %unicode_map.
	* tp/Texinfo/Convert/Plaintext.pm (converter_initialize):
	If @documentencoding were not given and we are converting to 
	UTF-8, set 'no_extra_unicode' on the 'convert_text_options' 
	hash, and do not use any curly quotes for style commands.
	* tp/Texinfo/Convert/Plaintext.pm (_process_text): Do not 
	convert `` into “, etc unless @documentencoding was in the 
	document.
	* tp/Texinfo/Convert/Text.pm (brace_no_arg_command):
	Check 'no_extra_unicode' in the options and if it is set, 
	exclude commands in %extra_unicode_map being output as non-ASCII 
	UTF-8 sequences.

2019-02-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (@titlepage): Remove documentation of 
	@setcontentsaftertitlepage.

2019-02-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove unused code.

	* tp/Texinfo/Parser.pm (%tree_informations, duplicate_parser),
	* tp/Texinfo/XS/parsetexi/Parsetexi.pm (duplicate_parser):
	Remove unused.

2019-02-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Make UTF-8 default input encoding.

	* doc/texinfo.tex: Remove line setting catcodes of non-ASCII 
	characters to "other".  Change a comment.
	* tp/t/test_sort.t: Update results.
	* tp/Texinfo/Common.pm (%default_customization_values)
	<INPUT_ENCODING_NAME, INPUT_PERL_ENCODING>: Use UTF-8 by default.
	* NEWS: Mention change.

2019-02-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Avoid unnecessary change in test results.

	* tp/Texinfo/Convert/HTML.pm: Add 'return undef' to end of 
	function.  This stops an empty string being returned from the 
	sub for some reason.  This led to a change in the results
	for 'file_html' tests.

2019-02-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Load more modules on demand.

	* tp/Texinfo/Convert/Converter.pm: Use fewer "use" declarations.
	(converter, sort_element_count): Use "require" statements
	to load modules on demand.  This cuts down the run time of
	'texi2any --help' as it stops Texinfo::Parser being loaded
	(about 0.6 sec -> 0.4 sec on my computer).

	This change depends on the previous change for module 
	namespaces; otherwise, the Texinfo::Parser::parser subroutine 
	can't be called in texi2any.pl, as the wrong hash is being 
	referenced for %Texinfo::Parser::.  This could be worked around 
	by putting the call within an 'eval' statement to delay the 
	choice of which namespace hash to use; however, this would be 
	too distracting if done too much.

2019-02-23  Gavin Smith  <gavinsmith0123@gmail.com>

	Avoid package typeglob assignment.

	* tp/Texinfo/ParserNonXS.pm: Use "package Texinfo::Parser" 
	instead of "package Texinfo::ParserNonXS" and then aliasing the 
	package namespace hash with a typeglob assignment.  Move
	"use Texinfo::Report" earlier in file and remove lengthy 
	comment.

	* tp/Texinfo/XS/parsetexi/Parsetexi.xs: Use "Texinfo::Parser" 
	instead of "Parsetexi" in MODULE and PACAKGE declarations.

	Package typeglob assignment is not recommended in the Perl 
	documentation anywhere, and has confusing effects.  It appears 
	that when a Perl source file is read, the symbols are 
	interpreted in terms of a particular package namespace hash.  
	This hash does not change if the package hash is later 
	reassigned, which can lead to undefined symbols, especially with 
	complicated situations when files "use" one another.

2019-02-19  Gavin Smith  <gavinsmith0123@gmail.com>

	Prefer @url in the documentation.

	* doc/texinfo.texi (@url, @url Examples): Use @url consistently 
	and say that @uref is a synonym.  Akim Demaille reported that a 
	confusing mixture of the two was being used.

2019-02-19  Gavin Smith  <gavinsmith0123@gmail.com>

	@documentencoding is not file-specific.

	* tp/Texinfo/XS/parsetexi/input.c (input_encoding): New 
	variable.
	(set_input_encoding, next_text):
	Use that encoding instead of an encoding on the input stack.

	(INPUT): Remove field 'encoding'.
	(input_push, input_push_file): Update.

	Eli Zaretskii reported that a @documentencoding command in an
	@include'd file would not take effect outside of that file, 
	which was wrong for the Emacs manuals.
	
2019-02-17  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove noderename.cnf feature.

	* tp/Texinfo/Common.pm (@variable_string_settables):
	Remove 'RENAMED_NODES_DIRECTIONS', 'RENAMED_NODES_FILE'.
	(collect_renamed_nodes, parse_renamed_nodes_file): Remove.

	* tp/Texinfo/Convert/HTML.pm
	(converter_initialize): Do not check Texinfo::Config::renamed_nodes.
	(_file_header_informations): Change a comment.
	(output): Do not call Texinfo::Common::collect_renamed_nodes.  
	Remove code dealing with renamed nodes.
	(_parse_node_and_warn_external): Remove unused.  This eliminates 
	the dependecy of Texinfo::Convert::HTML on Texinfo::Parser.

	* tp/tests/Makefile.am: Remove code dealing with copying 
	renamednodes.cnf-ref.
	* tp/tests/sectioning/renamednodes.cnf-ref: Remove.
	* tp/tests/sectioning (equivalent_nodes_test_renamed_nodes): Remove.
	* tp/tests/README: Update instructions for git.

	* tp/t/92formatting.t (unknown_nodes_renamed): Remove.

	* doc/texinfo.texi (Other Customization Variables) 
	<RENAMED_NODES_FILE, RENAMED_NODES_REDIRECTIONS>: Remove.

2019-02-17  Gavin Smith  <gavinsmith0123@gmail.com>

2019-02-17  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove 'termio' support.

	* configure.ac: Do not check for termio.h or sys/ptem.h.
	* info/termdep.h, info/terminal.c:

	AC_TYPE_SIGNAL, AC_C_CONST, AC_STRUCT_TM, AC_FUNC_VPRINTF.  
	Remove commented-out use of AC_FUNC_SETVBUF_REVERSED.

	* info/signals.c, info/terminal.c: Remove use of RETSIGTYPE for 
	signal handlers.

	Some of these are noted in the autoconf or gnulib manuals as 
	being unnecessary.

2019-02-17  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove customization value OUT.

	* tp/Texinfo/Common.pm (@command_line_settables),
	* doc/texinfo.texi (Customization Variables and Options):
	Remove 'OUT'.
	* tp/texi2any.pl: Do not use 'OUT' as a customization variable 
	and use 'OUTFILE' instead to check if the name of the output 
	file has been given.

2019-02-17  Gavin Smith  <gavinsmith0123@gmail.com>

	Re-use open file descriptor.

	* info/t/Init-test.inc: Change a comment.

	every time.

2019-02-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* configure.ac: Bump version to 6.6dev.

2019-02-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Documentation of @pxref.

	* doc/texinfo.texi (@pxref): Do not encourage using @pxref 
	outside of parentheses.  "see @ref" is often preferable to 
	"@pxref".

2019-02-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Minor changes to info-stnd.texi.

	* doc/info-stnd.texi
	(Invoking Info): Use a consistent name for menu arguments.
	(Moving the Cursor): Change 'imprinted on' to 'printed on'.  
	Move a footnote reference to the end of a sentence.
	(Node Commands): Correct key used in description.
	(The Echo Area) <printing characters>: Do not mention this 
	command, as self-inserting characters are inserted with a 
	different part of the code.  Do not mention about checking 
	whether a Meta key is bound, as this only applies if ISO-Latin 
	is 'Off'.
	<echo-area-complete>: SPC is not bound to this command any more.
	<echo-area-possible-completions>: Merge text with documentation 
	of 'echo-area-complete'.  '?' does not run this command any 
	more.
	(Colors and Styles): Privilege American spelling of "color".

	Fix too wide space in @verbatiminclude.

	* doc/texinfo.tex (\verbatiminclude): Confine the effect of 
	\indexnofonts to a group where the filename is read, as is done

	that a wider space would be output after a colon in a file input 
	with @verbatiminclude.

2019-02-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Use an m4 loop.

	* tp/Texinfo/XS/configure.ac (lookup_perl_conf_values): New 
	macro, to use m4_foreach (from autoconf m4sugar) to look up 
	several values with lookup_perl_conf.

2019-01-31  Gavin Smith  <gavinsmith0123@gmail.com>

	Do not require xsubpp.

	* tp/Texinfo/XS/configure.ac: Check for xsubpp with 
	AM_MISSING_PROG instead of AC_PATH_PROG, as xsubpp is not 
	required unless a *.xs file is modified.

	* info/session.c (info_search_internal): If a node couldn't be 
	found, go onto the next node.
	This could happen if there was a comma in a node name.

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove duplicate sub definition.

	* Pod-Simple-Texinfo/pod2texi.pl (__): Remove definition as 
	there is already one exported by Texinfo::Common (for translated 
	strings).

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Try to fix contrib/perldoc-all.

	* contrib/perldoc-all/gendocs-sh: Add, from gendocs.sh in gnulib 
	project.
	* contrib/perldoc-all/Makefile.am: Access it instead of relying 
	on gendocs.sh being in path.  Do not remove *.?? (intending to 
	remove auxiliary index files) as this may delete the *.tar.gz 
	file the user has just downloaded.

	Keith Thompson reported problems with building Perl manuals with 
	this system.

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Centralise parser configuration values.

	* tp/Texinfo/ParserNonXS.pm,
	* tp/Texinfo/Common.pm (%default_customization_values):
	Move to Common.pm.
	* tp/Texinfo/XS/parsetexi/Parsetexi.pm: Use this hash instead of 
	having a separate copy for this module.

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove 'parent_type' field.

	* tp/Texinfo/XS/parsetexi/tree_types.h (ELEMENT):
	Remove field 'parent_type'.
	(enum route_element_type): Remove.
	* tp/Texinfo/XS/parsetexi/end_line.c (end_line_starting_block)
	(end_line),
	* tp/Texinfo/XS/parsetexi/indices.c (wipe_index),
	* tp/Texinfo/XS/parsetexi/api.c (build_perl_array)
	(build_single_index_data): Check whether 'parent' is null to see 
	if an element is in tree.  This should work for all elements 
	except the root of the tree.

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove reference line numbers in parsetexi.

	* tp/Texinfo/XS/parsetexi: Remove most of the comments with what 
	the line numbers were of the corresponding Perl code at the time 
	that parsetexi was first started.  Leave some where more work 
	might be needed.
	* tp/Texinfo/XS/parsetexi/main.c: Remove.
	* tp/Texinfo/XS/parsetexi/Common.pm: Remove.

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove old files from parsetexi subdirectory.

	* tp/Texinfo/XS/parsetexi/complete_tree.pl,
	* tp/Texinfo/XS/parsetexi/debug_perl.txt,
	* tp/Texinfo/XS/parsetexi/makeinfo-debug.txt: Remove.

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove relics of ExtUtils::MakeMaker build system.

	* tp/Texinfo/XS/Makefile.PL,
	* tp/Texinfo/XS/MANIFEST,
	* tp/Texinfo/XS/prepare_standalone_perl_module.sh: Remove.
	* tp/Texinfo/XS/Makefile.am (perl_specific_files): Remove.

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove relics of ExtUtils::MakeMaker build system.

	* tp/Makefile.PL, tp/MANIFEST: Remove.
	* tp/maintain/MANIFEST_generated_files: Remove.
	* tp/maintain/MANIFEST_perl_po: Remove.
	* tp/maintain/prepare_perl_module_files.sh,
	* tp/maintain/prepare_perl_standalone_module_archive.sh,
	* tp/maintain/clean_perl_module_files.sh: Remove.

	* tp/Makefile.am (MANIFEST, perl_specific_files): Remove.

	This was for creating "standalone modules", but it is 
	out-of-date, doesn't work and has never been used.

2019-01-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove test from 'many_input_files' subdirectory.

	* tp/tests/many_input_files/indices.sh: Remove.
	* tp/tests/indices/list_of_tests (index_table): New test to 
	partially replace indices.sh.  Only one input file is tested.

	This test tested that texi2any would work with several manuals 
	to process given to it on the command line.  I suspect this 
	feature is rarely used.  The extra complexity this gave to the 
	test suite is not worth it IMHO.
	Now the many_input_files subdirectory only contains the 
	latex2html and tex4ht tests, which are not run by default.

	I checks that the output for the index_table.texi file was the 
	same by checking the same files were output and that the 
	contents were the same, with a command like
	  for f in * ; do echo DIFF $f ;
	  diff $f ../../../many_input_files/indices_res/$f ; done

2019-01-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Use 'id' instead of 'name' attribute.

	* tp/Texinfo/Convert/HTML.pm (_convert_footnote_command),
	(_default_contents):
	Use 'id' instead of 'name' attribute on <a> tag.

2019-01-27  Gavin Smith  <gavinsmith0123@gmail.com>

	Comments in parsetexi header files.

	* tp/Texinfo/XS/parsetexi: Add a brief comment at the start of 
	each header file.
	* tp/Texinfo/XS/parsetexi/tree_types.h,
	* tp/Texinfo/XS/parsetexi/conf.h (CONF): Move to conf.h.
	* tp/Texinfo/XS/parsetexi/errors.c: Remove #define _GNU_SOURCE.

2019-01-27  Gavin Smith  <gavinsmith0123@gmail.com>

	Header file changes and small fixes for parsetexi.

	* tp/Texinfo/XS/parsetexi/tree_types.h,
	* tp/Texinfo/XS/parsetexi/macro.h (INFO_ENCLOSE, MACRO):
	Move to text.h.
	* tp/Texinfo/XS/parsetexi/close.c (close_command_cleanup): Fix 
	incorrect comparison of enum values.
	* tp/Texinfo/XS/parsetexi/separator.c (handle_close_brace): 
	Remove an unused variable.
	* tp/Texinfo/XS/parsetexi/tree_types.h,
	* tp/Texinfo/XS/parsetexi/errors.h (enum error_type):
	Move to text.h.

2019-01-26  Bruno Haible  <bruno@clisp.org>

	Fix test failures on HP-UX.

	Reported by Richard Lloyd in
	<https://lists.gnu.org/archive/html/bug-texinfo/2013-02/msg00030.html>.

	* install-info/tests/ii-0041-test: Simulate zdiff.
	* install-info/tests/ii-0050-test: Likewise.

2019-01-25  Gavin Smith  <gavinsmith0123@gmail.com>

	Make "texi2dvi --command" work without @setfilename in file.

	* util/texi2dvi (insert_commands, usage):  Insert commands given 
	with --command even if no @setfilename line is present.
	* doc/texinfo.texi (Format with texi2dvi) <--command>: Remove 
	mention of @setfilename.

2019-01-25  Gavin Smith  <gavinsmith0123@gmail.com>

	Attempt to make test suite parallel safe.

	* tp/maintain/regenerate_cmd_tests.sh: Use 'mkdir -p' instead
	of testing whether directory exists.
	* tp/tests/run_parser_all.sh: Use 'mkdir -p' instead of testing 
	if a directory exists.  Do not delete a temporary directory at 
	the end.  Redirect stdin with "exec" instead of just redirecting 
	a "while" loop in order to avoid problem with redirecting output 
	under Solaris 10 shell.

	Andreas Schwab reported that the test suite was not parallel 
	safe.

2019-01-24  Gavin Smith  <gavinsmith0123@gmail.com>

	Pass on -D flags to texi2dvi.

	* tp/texi2any.pl: If calling texi2dvi, only pass along the 
	values of flags before the file is parsed: not the values after 
	the file is parsed.  These values might be wrong for the start 
	of the file.

	Stefan Husmann found that the Tramp manual wouldn't build with 
	pretest texinfo-6.5.91

2019-01-20  Gavin Smith  <gavinsmith0123@gmail.com>

	Check for gawk version for rebuilding texindex.awk.

	* configure.ac: Use AM_MISSING_PROG to look for gawk.
	* texindex/Makefile.am (texindex.awk, ti.twjr): Use $(GAWK) 
	instead of $(AWK).
	* texindex/jrtangle: Add a check for the version number of gawk 
	and, if too old, exit with status 63 in order to let the 
	"missing" script know it is too old.

	Bruno Haible reported that the rule to regenerate texindex.awk
	was being run on OpenBSD 6.3 where there was no gawk.

2019-01-16  Gavin Smith  <gavinsmith0123@gmail.com>

	Documentation of colons in index entries.

	* doc/texinfo.texi (Index Commands):
	Water down the proscription of colons in an index entry, as this
	works with some Info readers.

2019-01-14  Gavin Smith  <gavinsmith0123@gmail.com>

	Split code into separate file.

	* tp/Texinfo/XS/parsetexi/conf.c: New file, along with header.  
	This helps us to avoid declaring the 'conf' variable in two 
	different header files.

2019-01-14  Gavin Smith  <gavinsmith0123@gmail.com>

	Rearrange header files.

	* tp/Texinfo/XS/parsetexi/debug.c: Include header file 
	containing declarations of functions in this file.
	* tp/Texinfo/XS/parsetexi/end_line.c,
	* tp/Texinfo/XS/parsetexi/separator.c: Remove an unnecessary #include.

2019-01-14  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove unused API functions.

	* tp/Texinfo/XS/parsetexi/Parsetexi.xs (element_type_name)
	(num_contents_children, num_args_children, contents_child_by_index):
	Remove ununused XSUB's.

	* tp/Texinfo/XS/parsetexi/api.c (num_contents_children) 
	(num_args_children): Remove unused.

2019-01-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/parsetexi/Parsetexi.pm: Remove a generated comment.

2019-01-14  Gavin Smith  <gavinsmith0123@gmail.com>

	Move function declarations to header file.

	* tp/Texinfo/XS/parsetexi/Parsetexi.xs: Move function 
	declarations to header file, api.h.  This means the compiler can 
	check the declarations are consistent with the definitions in 
	api.c.

2019-01-14  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove an unnecessary #include.

	* tp/Texinfo/XS/parsetexi/input.c,
	* tp/Texinfo/XS/parsetexi/parser.c: Remove an unnecessary 
	#include "api.h".

2019-01-14  Gavin Smith  <gavinsmith0123@gmail.com>

	Move a function between files.

	* tp/Texinfo/XS/parsetexi/api.c,
	* tp/Texinfo/XS/parsetexi/parser.c (element_type_name): Move to 
	parser.c.

2019-01-13  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove some unused variables.

	* tp/Texinfo/XS/parsetexi/separator.c (handle_close_brace):
	Remove some unused variables.

2019-01-13  Gavin Smith  <gavinsmith0123@gmail.com>

	pretest 6.5.91.

	* configure.ac: version

2019-01-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/man.c: Include stdio.h.

2019-01-12  Hans-Bernhard Bröker  <HBBroeker@t-online.de>  (tiny change)

	Fix some warnings.

	* tp/Texinfo/XS/parsetexi/close.c: Initialize a variable.

2019-01-12  Hans-Bernhard Bröker  <HBBroeker@t-online.de>  (tiny change)

	Fix some warnings.

	* tp/Texinfo/XS/parsetexi/end_line.c: Fix an unterminated 
	comment.
	(check_empty_node): Avoid reaching end of undefined function.
	* tp/Texinfo/XS/parsetexi/parser.c (register_global_command): 
	Add default cases.
	* tp/Texinfo/XS/parsetexi/multitable.c (gather_previous_item):
	Correct enum type in variable declaration.

2019-01-12  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove unused variables.

	* tp/Texinfo/XS/parsetexi/api.c (element_to_perl_hash),
	* tp/Texinfo/XS/parsetexi/parser.c (register_global_command)
	(process_remaining_on_line),
	* tp/Texinfo/XS/parsetexi/convert.c (expand_cmd_args_to_texi),
	* tp/Texinfo/XS/parsetexi/end_line.c (parse_line_command_args)
	(end_line_starting_block, end_line_misc_line),
	* tp/Texinfo/XS/parsetexi/macro.c (expand_macro_body),
	* tp/Texinfo/XS/parsetexi/handle_commands.c (handle_other_command),
	* tp/Texinfo/XS/parsetexi/def.c (split_delimiters, split_def_args)
	(parse_def): Remove declarations of unused variables.

2019-01-12  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove an unused variable.

	* tp/Texinfo/ParserNonXS.pm (_parse_texi): Remove an unused 
	variable.

2019-01-12  Gavin Smith  <gavinsmith0123@gmail.com>

	Add a default case.

	* tp/Texinfo/XS/parsetexi/parser.c (process_remaining_on_line): 
	Add an empty default clause in switch block.

2019-01-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/parsetexi: Fix implicit function declarations.

2019-01-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Make Parsetexi XS module conditional on iconv.

	* tp/Texinfo/XS/configure.ac: Add an AM_CONDITIONAL checking 
	whether gnulib found that iconv worked.
	* tp/Texinfo/XS/Makefile.am: Make building Parsetexi module 
	conditional.

2019-01-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Set PERL_EXT_var in configure.ac.

	* tp/Texinfo/XS/configure.ac,
	* tp/Texinfo/XS/Makefile.am: Move setting of CFLAGS, CPPFLAGS 
	and LDFLAGS from PERL_EXT_CFLAGS, PERL_EXT_CPPFLAGS and 
	PERL_EXT_LDFLAGS from Makefile.am to configure.ac in order that 
	they are used during the Gnulib checks.  Report from Bruno Haible.

2019-01-07  Gavin Smith  <gavinsmith0123@gmail.com>

	No buffering for pseudotty output.

	* info/pseudotty.c: Set VMIN value on the c_cc array in the 
	termios structure to 1, meaning 'read' can return with a single 
	byte.  (The default value on Solaris 10 was found to be 4, which 
	may be C-d for end-of-file.)  Also set VTIME to 0.

2019-01-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Turn off canonical input processing in pseudotty.

	* info/pseudotty.c [HAVE_TERMIOS_H]: Clear the ICANON and ECHO 
	flags.

	In the test suite, if bytes were passed through the pseudotty 
	program before ginfo could make this change, they could be 
	subject to undesired processing.  This was not apparent as info 
	treated '\n' the same as '\r'.  This could be shown by using a 
	"dribble" file and inserting a "sleep" in one of the test scripts.
	Tests were failing on Solaris 10 and Solaris 11 because bytes 
	that were supposed to be sent to ginfo were being buffered, 
	awaiting a newline.

2019-01-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Do not send debug output to infodebug file.

	* info/session.c (vinfo_debug): Always sent debugging output to 
	stderr.
	(close_debugfile, debug_file): Remove.
	* doc/info-stnd.texi (Invoking Info): Update.
	* NEWS: Mention change.

	This is to make all the debugging output from info appear 
	together in a log files when output is diverted from a test 
	script.

2019-01-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Avoid possible infinite loop in info test suite.

	* info/t/replace-viewed.sh: Replace a loop that waits for ginfo 
	to create a file with a "sleep" statement.  If the file weren't 
	created, this would be an infinte loop.

2019-01-07  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove useless code in info test suite.

	* info/t/replace-viewed.sh,
	* info/t/resize-in-completions: Do not check for a variable 
	having a value that no code sets it to.  This has been the case 
	since the way the PID of the process was found changed.

2019-01-06  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix info tests under Solaris.

	* info/pseudotty.c [__sun]: Additionally perform a "ttycompat"
	ioctl on the slave fd.  This is what is done in the gnulib 
	openpty module.  Since these ioctls were no longer guarded by 
	isatty, it would lead to some of the info tests failing.  I 
	don't know under what conditions the ioctls are actually needed 
	under Solaris: possibly they aren't needed at all.

2019-01-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Include iconv.h unconditionally.

	* tp/Texinfo/XS/parsetexi/input.c: Do not depend on HAVE_ICONV 
	for #include <iconv.h>.  Use of iconv_t, iconv_open etc. later 
	on in the file is not conditional, and we don't have a way to 
	avoid using these.  It's possible that gnulib set HAVE_ICONV to 
	0 because it found that iconv.h was buggy, even if it existed.

2019-01-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Don't use variable in SOURCES in Makefile.am.

	* tp/Texinfo/XS/Makefile.am (Parsetexi_la_SOURCES, BUILT_SOURCES):
	Write out "parsetexi" explicitly instead of hiding it inside $p.
	Although the latter works with automake 1.16 (which we are 
	using), the OpenCSW buildbot still uses automake 1.15.1, leading 
	to build failures.

2019-01-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Integrate parsetexi with gnulib.

	* tp/Texinfo/XS/parsetexi/input.c: Do not define ICONV_CONST.

2019-01-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Fall back to pure Perl module when TEXINFO_XS_PARSER is set.

	* tp/Texinfo/Parser.pm, tp/Texinfo/ParserNonXS.pm: Rename file.
	* tp/Texinfo/ParserNonXS.pm: Make module symbols available under 
	both Texinfo::Parser and Texinfo::ParserNonXS.
	* tp/Texinfo/ModulePath.pm.in: If TEXINFO_XS_PARSER is not set, 
	load Texinfo/ParserNonXS.pm instead of Texinfo/Parser.pm.
	* tp/Texinfo/XS/parsetexi/Parsetexi.pm: Pass Texinfo::ParserNonXS
	as a fallback module to Texinfo::XSLoader::init.  Comment out 
	line to reset_parser in END block, as this won't work if 
	Texinfo::ParserNonXS is loaded.

2019-01-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix info test suite hang under HP-UX 11.31.

	* info/pseudotty.c [HAVE_STROPTS_H]: Do not call isatty on 
	pseudoterminal file descriptor.  Bruno Haible reported that this 
	made a test hang.  Do not use HAVE_STROPTS_H condition: replace 
	with "#if defined(__hpux) || defined(__sun)", as is done in 
	gnulib.  Remove some commented-out code.
	* configure.ac (AC_CHECK_HEADERS): Do not check for stropts.h.

2019-01-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Improve XS loading error message.

	* tp/Texinfo/XSLoader.pm: Improve error message in the case that 
	a module couldn't be loaded.

2019-01-05  Bruno Haible  <bruno@clisp.org>

	Fix build errors on AIX 7.1.

	* info/Makefile.am (LDADD),
	* install-info/Makefile.am (LDADD): Add $(LIBTHREAD).

2019-01-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Check for Data::Dumper.

	* configure.ac: Check for Data::Dumper as well as Encode.  Bruno 
	Haible reported that Data::Dumper was missing on CentOS 7.3.

2019-01-05  Gavin Smith  <gavinsmith0123@gmail.com>

	Combine Makefiles for XS modules.

	* tp/Texinfo/XS/configure.ac (AC_CONFIG_FILES): Remove Makefile 
	in parsetexi subdirectory.
	* tp/Texinfo/XS/Makefile.am: Merge in contents of 
	tp/Texinfo/XS/parsetexi/Makefile.am.
	* tp/Texinfo/XS/parsetexi/Makefile.am: Remove file.

	This means that passing -lperl when linking will always be 
	conditional on HOST_NEEDS_NO_UNDEFINED.

2019-01-04  Gavin Smith  <gavinsmith0123@gmail.com>

	pretest 6.5.90.

	* configure.ac: version

	with Texinfo any more.  Update to three-column format used now 
	by gnulib srclist-update.  Update locations of automake files.
	* README-hacking: Update instructions for git.
	* configure.ac (TEXINFO_DTD_VERSION): Increase to 6.6.
	* doc/refcard/txirefcard.tex: Update version and copyright year.

	Fix unclosed @inlinefmtifelse.

	* tp/Texinfo/XS/parsetexi/separator.c (handle_comma): If we run 
	out of input inside @inlinefmtifelse, exit the function.  This 
	matches change to Perl code made on 2018-10-29.

2019-01-03  Gavin Smith  <gavinsmith0123@gmail.com>

	* README-hacking: Update instructions to use git.

2019-01-03  Gavin Smith  <gavinsmith0123@gmail.com>

2019-01-03  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove obsolete comment.

	* util/texi2dvi: Remove comment about use of file descriptors
	3 and 4.  (See info node '(autoconf)File Descriptors'.)  Remove 
	comment about EGREP variable alluding to the fact that the

	* README-hacking: Remove mention of these subdirectories.

2019-01-02  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove unused variable in test suite.

	* tp/maintain/regenerate_cmd_tests.sh: Do not set 'srcdir_test' 
	in generated test scripts, as this variable is no longer used 
	anywhere.
	* tp/tests/run_parser_all.sh: Remove commented-out code.

2019-01-02  Gavin Smith  <gavinsmith0123@gmail.com>

	(copy-tests, copy-tex-html): Work properly in out-of-source builds.

2019-01-02   Per Bother  <per@bothner.com>

	Use 'id' attribute instead of 'name' on <a>.

	* tp/Texinfo/Convert/HTML.pm:
	(_convert_float_command, _convert_item_command)
	(_convert_index_command, _contents_inline_element)
	(_convert_element_type, _convert_heading_command):
	Use '<span id>' instead of '<a name>'.
	(_convert_printindex_command, _convert_def_line_type):
	Add 'id' attribute to <th> and <dt> elements, and remove
	<a name>.

	The 'name' attribute of <a> to define a hyperlink target is 
	deprecated in the HTML 5 standards.  'id' for this purpose was 
	specified by HTML 4 (in 1997) and can be expected to be 
	supported by all browsers.

2019-01-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Document SECTION_NAME_IN_TITLE.

	* doc/texinfo.texi (HTML Customization Variables),

	New customization variable SECTION_NAME_IN_TITLE.

	* tp/Texinfo/Common.pm (@variable_string_settables),
	* tp/Texinfo/Convert/HTML.pm (%defaults):
	Add SECTION_NAME_IN_TITLE.
	* tp/Texinfo/Convert/HTML.pm (_file_header_information): For 
	split output, if SECTION_NAME_IN_TITLE is set, try to use the 
	argument of the chapter structuring command instead of @node for 
	the contents of <title>.  Feature suggestion from Akim Demaille
	(help-texinfo, Nov. 2018).

2019-01-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix error message from texinfo-js.

	* js/texinfo-js.in: Remove extra `-' from an error message.  
	Report from Stefan Husmann.

2018-12-31  Gavin Smith  <gavinsmith0123@gmail.com>

	Document 'TEXINFO_XS_PARSER'.

	* NEWS: Mention the XS parser implementation.
	* tp/Texinfo/Parser.pm: Note that this module can be overridden.
	* doc/texinfo.texi (texi2any Environment Variables):
	Add TEXINFO_XS_PARSER.

2018-12-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Pass on -D to texi2dvi.

	* tp/texi2any.pl: If calling texi2dvi, pass along the values of 
	any flags set with -D on the command line.  Suggestion from 
	Olivier Dion.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove implementation of @cropmarks in texi2any.

	* tp/Texinfo/Common.pm (%line_commands): Remove 'cropmarks'.
	* tp/Texinfo/XS/parsetexi/command_data.txt: Remove cropmarks.
	* tp/t/xml_tests.t (commands_and_spaces),
	* tp/t/08misc_commands.t (also_not_line),
	* tp/t/50value.t (value_in_misc_commands),
	* tp/t/60macro.t (macro_in_misc_commands):
	Remove @cropmarks from tests.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove documentation of @cropmarks command.

	* doc/texinfo.texi (Cropmarks and Magnification, Magnification):
	Rename and remove mention of @cropmarks.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove @cropmarks command.

	* doc/texinfo.tex (\cropmarks, \ifcropmarks, \onepageout): 
	Remove implementation of @cropmarks.
	* NEWS: Mention @cropmarks removal.

	This command has hardly ever been used and it is questionable 
	whether it has worked correctly for many years.  See bug-texinfo 
	discussion November 2018.
	The code was introduced in 1986 by Pierre MacKay for use by 
	"Near East Publications".

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Tidy up info test suite infrastructure.

	* info/t/Init-test.inc: Do not set GINFO_NAME variable as it is 
	not used.  Do not set infodir variable.  Do not try to set 
	srcdir, as it is already set.  Change some shell variables to be 
	lower-case, to avoid confusion with variables exported to the 
	environment.  Remove unused variable GINFO_OPTIONS.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Select correct cross-reference.

	* info/session.c (info_menu_or_ref_item): If there is more than 
	one cross-reference in the line after the point and no 
	cross-reference contains the point, use the first 
	cross-reference after the point, not the last one in the line.  
	This means that the cross-reference that is highlighted as 
	"active" will be the one that is used.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Avoid memory leak for malformed files.

	* info/nodes.c (info_load_file): Free 'contents' and 'encoding' 
	fields of file structure in case the node table couldn't be 
	built.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix call to info_find_file.

	* info/nodes.c (info_get_nodes_with_defaults): Restore the value 
	of the 'fullpath' field of a file structure before calling 
	info_find_file.  Otherwise, info_find_file will not recognize 
	that a file has been loaded, and load it again.  This can lead 
	to a file buffer being freed incorrectly in 
	gc_file_buffers_and_nodes, leading to a segmentation fault.  
	Segmentation fault reported by Keith Thompson.

2018-12-01  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Makefile.am (Makefile.docstr): Fix to work out-of-source.

2018-12-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix info/t/all-only.sh test in out-of-source builds.

	* info/dir.c (dir_entry_of_infodir): Prefix a non-absolute path 
	with "./" so that other parts of the code recognize it is the 
	full path.

2018-12-01  Gavin Smith  <gavinsmith0123@gmail.com>

	* NEWS: Development now uses git.

2018-10-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <inline conditionals>:
	Avoid an infinite loop when skipping an unexpanded conditional
	in case we run out of input.
	* tp/t/55conditionals.t (inlineifset_false_not_closed): New test.

2018-10-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <@inlinefmtifelse>:
	Avoid an infinite loop if there is no more input.
	* tp/t/55conditionals.t
	(inlineiffmtifelse_not_closed, inlineiffmtifelse_not_closed_two_arg)
	(inlineiffmtifelse_not_closed_three_arg): New tests.

2018-10-28  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_check_line_directive): Fix code for
	checking if input is coming from a file.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_next_text, _new_line): Do not pass
	$current as an argument, as it is not used any more now the
	check for the #line directive has been moved out.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/80include.t (cpp_lines): Add test of macro where a
	line that looks like a #line directive is not the very first
	line, as these may be treated differently by Parser.pm.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_check_line_directive, _save_line_directive)
	(_next_text): Split out sub from _next_text.
	(_parse_texi) <BEGIN LINE>: Call _check_line_directive and
	_save_line_directive.  The condition for #line being meaningful 
	is the same as what was in _next_text.  

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (#line directive) <CPP_LINE_DIRECTIVES>:
	Add a missing ).

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (@obsolete_variables): Remove.
	(obsolete_option): Remove.
	(%customization_variable_classes): Remove 'obsolete_variables'.
	* tp/texi2any.pl (set_from_init_file, set_from_cmdline),
	* tp/Texinfo/Convert/Converter.pm (set_conf, force_conf):
	Do not call Texinfo::Common::obsolete_option.
	* NEWS: Mention that obsolete customization variables are no 
	longer recognized.

	* tp/Texinfo/Parser.pm (_setup_parser): Do not look at 
	'INLINE_INSERTCOPYING'.

	If more variables are deprecated, then it may be worth 
	reinstating some of this code.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_command_with_command_as_argument):
	Remove code checking for a case where the command has two 
	elements in 'args', the first all whitespace, as this case never 
	seems to happen.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (@titlefont @center @sp):
	Do not mention the possibility of using these outside of a title 
	page.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%in_index_commands): New hash, 
	containing only 'sortas'.
	* tp/Texinfo/Parser.pm (%in_full_text_commands): Do not 
	specially remove 'sortas'.
	(_setup_parser, _parse_command_line_args): Use 
	%in_simple_text_commands for the commands that may appear in 
	index commands.  This was done until 2017-04-01.
	(_parse_texi) <brace commands>: Move check for valid nesting of 
	@sortas here.  Change error message to mention index entry.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <in heading commands>:
	Do not set an 'invalid_nesting' value.

2018-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_check_valid_nesting): New sub, split 
	out from _parse_texi.
	(_parser_texi): Call it.
	(%in_full_line_commands): Remove useless variable, as the same
	as %in_full_text_commands.

2018-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%in_full_text_commands): Do not
	allow @indent, @noindent.
	(%in_full_line_commands): No exception for @indent, @noindent.
	* NEWS: Mention change in allowed nesting.

2018-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%simple_text_commands): Add all the 
	commands that have a number >= 1 as their argument type in
	%brace_commands, except for inline conditional commands.  This 
	includes @inforef which wasn't included before.  This leaves 
	only @shortcaption and @math as explicitly listed commands.

2018-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%no_command_commands): Remove this list 
	of commands that shouldn't contain any other commands.  Although 
	it is valid, it makes the picture of which commands can contain 
	others more complicated for the sake of only a few commands.
	Introduced on 2016-07-09 for @errormsg and @U.

2018-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%brace_commands): Change meaning of 1
	as a value.  Now only commands that were in
	%simple_text_commands in Parser.pm have 1.  Use words as well as 
	numbers, as is done for %line_commands.  Accent commands get 
	'accent'.  Style commands get 'style'.  Context brace commands
	get 'context'.  Various other brace commands get 'other'.
	(_parse_line_command_args): Commands defined by @definfoenclose
	get 'style'.

	* tp/Texinfo/Parser.pm
	(%simple_text_commands): Change initialising code to use 
	%brace_commands for some brace commands. This shortens a 
	seemingly arbitrary list.

	(%full_text_commands): Update initialising code for new meaning 
	of %brace_commands.

	(_parse_texi): Change two conditions to compare values of 
	%brace_commands hash, without needing to look at 
	%simple_text_commands.  Remove an unnecessary conditional.

	* tp/Texinfo/Parser.pm (_parse_texi),
	* tp/Texinfo/Convert/Plaintext.pm (%brace_no_arg_commands):
	Use "eq '0'" instead of "== 0" for %brace_commands values.

	No functional changes intended.  This brings the implementation
	closer to the C version under tp/Texinfo/XS/parsetexi.

2018-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%simple_text_commands): Add 'sortas'.
	(%full_text_commands): No special case for 'sortas'.
	(_parse_texi) <@copying in @insertcopying>: Undefine a variable.

2018-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_isolate_last_space): Set 
	'comment_at_end' value on element instead of parent.  As well as 
	gaining consistency with 'spaces_after_argument', this means 
	that a comment at the end of a brace command argument is not 
	lost or output at the wrong place.  Add a comment noting that 
	comments should not be inside brace commands anyway.

	* tp/Texinfo/Convert/TexinfoXML.pm (_convert_argument_and_end_line),
	* tp/Texinfo/Convert/Texinfo.pm (convert, _expand_cmd_args_to_texi):
	* tp/Texinfo/Convert/Converter.pm _expand_cmd_args_to_texi): 
	Access 'comment_at_end' in the new place.

2018-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm: Change 'same than' to 'same as' in
	comments.

2018-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%simple_text_commands): Remove @ctrl.
	(_end_line): Change a comment.

	Change 'misc_line_arg' to 'line_arg'.

	* tp/Texinfo/Parser.pm
	(%begin_line_commands, %in_full_text_commands):
	Initialising code changed.

	* tp/Texinfo/Convert/Common.pm (@inline_types): Remove 
	'misc_command_arg', as no such element type is used anywhere.

	The reason for this change is that "line command" is more 
	descriptive than "miscellaneous command".  No functional changes 
	intended.

2018-10-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi): Check for unknown command

2018-10-21  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi):
	Issue an error message right after checking for an invalid 
	nesting.  This produces little functional change but is intended 
	to make the code easier to understand.
	(_mark_and_warn_invalid): Remove.

2018-10-21  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_mark_and_warn_invalid): Do not set 
	'invalid_nesting'.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%line_commands): Change a comment.
	(%other_commands): Set from %in_heading_commands.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%other_commands): Remove 'itemx'.  
	@itemx is always a line command.
	* tp/Texinfo/Parser.pm (_parse_texi) <misc commands>:
	Only @item can sometimes be an 'other' command', not @itemx.  
	Error message for incorrectly nested @item or @itemx.
	(_end_line): Add a check for an undefined value.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>


	* tp/Texinfo/Common.pm (%line_commands): Add all the sectioning, 
	index and def commands.
	* tp/Texinfo/Parser.pm (%misc_commands): Remove.
	(%line_commands): Add.
	(_setup_parser, simple_parser): Set 'line_commands' on parser 
	rather than 'misc_commands'.
	(_end_line, _parse_texi, _parse): Update.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <misc commands>:
	Deal with the commands that do not take a whole line as an 
	argument separately from those that do, using %other_commands 
	hash from Common.pm.  Reinstate error message for @insertcopying 
	inside @copying.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_item_line_parent): If current element 
	is an @item or @itemx, do not check the parent of the parent of 
	the current element.  This leads to a false positive for a 
	@table nested within an @enumerate.  It is possible that this 
	was intended to account for the parent element being a 
	'table_term' element, but the condition is not met in the entire
	test suite.  (The false positive was not hit in practice due to 
	_item_container_parent being called before _item_line_parent.)

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%line_commands, %deprecated_commands):

	* tp/Texinfo/Parser.pm (_end_line) <@multitable>: Give a warning

	outside of a braced prototype.

2018-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/tests/sectioning/list-of-tests: Do not run every test
	twice, once with '--html', once with '-c TEXI2HTML'.  Only use 
	the latter.

	* tp/tests/run_parser_all.sh: Do not substitute a
	"@PATH_SEPARATOR@" sequence in the list-of-tests files.
	It is only used in one test so is not worth the complication.
	* tp/tests/sectioning/list-of-tests (test_two_include):

2018-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl: Create the output directory for the test
	before running the conversion.  This means that if the test 
	needs to create output files, the directory to contain them will 
	exist.  It didn't exist the first time a test file was run when 
	the very first test in the file needed to create output.
	If there are conversion errors from texi2any, print them instead 
	of just printing a message "Warning: output generated".

	out-of-date.

2018-10-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl: Remove code copying 't/include_reference'

2018-10-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/info_tests.t (image_file_search): Remove test.
	test_include_directories): Remove tests.

	* tp/maintain/regenerate_file_lists.pl: Do not generate rules to 
	copy files to tp/t/include_dir in build directory.

	This avoids the hassle of copying all the include files to the 
	build directory for out-of-source builds and avoids the 
	confusion of which of "t/include", "t/include_dir" or 
	"t/include_reference" a test file is to be added to.  This 
	feature of the test suite is not used enough IMHO to be worth 
	the complexity.

2018-10-06  Gavin Smith  <gavinsmith0123@gmail.com>

	'columnfractions' extra value to the element for the 
	@columnfractions command, rather than to the 'misc_args' array 
	of that element.  This is to make a 'misc_args' array only 
	referenced by one element, which makes it possible to free the 
	memory properly in the C rewrite.

	* tp/tests/formatting/list-of-tests (texi_glossary):
	Define test using '-c TEXINFO_OUTPUT_FORMAT=plaintexinfo'.  This

	".txi" extension instead of "texi", and in the out_parser_info
	directory, the output format will be info instead of texi.

2018-09-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl: Allow '-c TEXINFO_OUTPUT_FORMAT' to override

	value.
	* tp/Texinfo/XS/misc.c (xs_abort_empty_line): Make the same change.

	This is intended to simplify the parse tree.  Reducing 
	duplication of information makes it easier to track what data 
	leads to output at later stages of processing.  It reduces 
	memory use and may increase speed.  It makes it easier to 
	inspect data structures that are "dumped" to a text stream.  It 
	is also easier to handle memory allocation in a rewrite in 
	another programming language if the data structures are less 
	cyclic.

2018-09-01  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/maintain/regenerate_cmd_tests.sh: Do not print diffs if

	* tp/Texinfo/Parser.pm (_parse_def): Change the type
	of final spaces elements to 'spaces_at_end'.  This leads to
	the spaces being ignored in some output formats.
	(_next_bracketed_or_word): Remove unused.
	* tp/Texinfo/Convert/TexinfoXML.pm (_convert) <def commands>:
	Strip off a final newline.

	* tp/Texinfo/Parser.pm (_split_delimiters): New function.
	(_parse_def): Do not produce def_args array via an intermediate

	conditional block that checks for a raw formatting command (e.g.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm
	(parse_def): Split up text elements in the main tree into 
	separate elements.  This means in most cases, the elements in 
	the 'def_args' hash and the elements in the main tree will be 
	the same.  (The exceptions are when "(" or ")" is split into a 
	"delimiter" element in def_args, and when there is trailing 
	whitespace on a line before the LF.)
	(next_bracketed_or_word): Include any trailing newline in the 
	returned values.
	(parse_def): Avoid adding elements with a trailing newline to 
	'def_args'.

	This change should only affect the main tree, not the value of 
	the 'def_args' hash, or the output from any of the converters.
	It is intended to reduce duplication of information in the parse 
	tree, and to make handling of allocated memory simpler in the C 
	replacement for this module.

2018-08-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/htmlxref.cnf: Remove gcj, info.  Add cvs.  Report from 
	Ineiev <ineiev@gnu.org> and Thérèse Godefroy <godef.th@free.fr>.

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/xspara.c (xs_unicode_text, xs_process_text):
	Use static buffers to avoid memory leaks.

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/xspara.c (xspara_get_pending, xspara_add_pending_word)
	xspara_end, xspara_add_next, xspara_add_text): Save storage for 
	text buffers in static variables to avoid memory leak.
	* tp/Texinfo/XS/text.c (text_reset): New function.

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/misc.c (xs_parse_texi_regex): Retain all memory
	allocated on the heap in static pointers.  Perl does not free 
	them, as when SV's are initialized with sv_setpv, the data 
	pointed to is copied, not the pointer itself.  This memory leak 
	is visible with valgrind, e.g. run TEXINFO_XS=debug PERL_DESTRUCT_LEVEL=2 valgrind --log-file=val.log --leak-check=full perl -w t/02coverage.t commands

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	or tp/MANIFEST.
	* tp/Texinfo/XS/Makefile.am: Do not distribute Makefile.PL,
	MANIFEST or prepare_standalone_perl_module.sh.

	for "make dist".

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/README: Clarify purpose of regenerate_file_lists.pl.  Do

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/ModulePath.pm.in: Add 'parsetexi' directory to 
	@INC.
	<TEXINFO_XS_PARSER environment variable set>: Add a subroutine 
	to @INC to override Texinfo::Parser with Parsetexi.pm.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl <finding version number>: Refer to

	other.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/Makefile.am: Do not install TestXS.pm, as this 
	is useless.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl: Only call fileparse once (used for both 
	finding modules and translation files).  Do not add a directory 
	to @INC that Texinfo::ModulePath takes care of adding.  Add a 
	comment.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* autogen.sh: Initialise tp/Texinfo/XS directory.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/Makefile.am (modulesdir): Change to new 
	location.
	(CLEANFILES, EXTRA_DIST, xs_LTLIBRARIES): Add MiscXS files.
	(MiscXS_la_CFLAGS): Define.

	* tp/Texinfo/MiscXS/MiscXS.pm,
	* tp/Texinfo/MiscXS/miscxs.h,
	* tp/Texinfo/MiscXS/misc.c: Move to tp/Texinfo/XS.
	* tp/Texinfo/MiscXS: Remove subdirectory.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/XSParagraph, tp/Texinfo/XS:
	Move subdirectory. This is intended to be a subdirectory for all 
	XS modules and to remove the duplication that exists between
	tp/Texinfo/Convert/XSParagraph and tp/Texinfo/MiscXS.

	* configure.ac,
	* tp/Makefile.am,
	* tp/Texinfo/Convert/Paragraph.pm,
	* tp/Texinfo/ModulePath.pm.in,
	* tp/Texinfo/XS/XSParagraph.xs,
	* tp/Texinfo/XS/TestXS.pm:
	Refer to Texinfo/XS subdirectory instead of 
	Texinfo/Convert/XSParagraph and namespaces beginning 
	"Texinfo::XS" instead of "Texinfo::Convert::XSParagraph".

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-test.inc: Do not check whether the terminal needs 
	to be reset with stty, because the command that caused this 
	problem ("read -t") is not being used any more.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/01use.t: Inline file tp/t/manual_tree.pl.

2018-08-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/ModulePath.pm.in (init): Remove subroutine 
	prototype.
	* tp/Texinfo/ModulePath.pm.in (import): Wrap 'init' to allow

	Add "use lib '.'" to add current working directory to @INC, the 
	Perl module include path.  This directory is not present in @INC 
	in recent versions of Perl, which makes running tests from the 
	command-line (like "perl -w t/02coverage.t") difficult.  Require 
	Texinfo::ModulePath to add all the other required directories to 
	@INC.  As tp/Texinfo/ModulePath.pm is generated in the builddir, 
	this should work for out-of-source builds.

2018-08-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/01use.t: Use Texinfo::ModulePath.

2018-08-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (parser): Remove code allowing calling 
	this function in an object-oriented way.

2018-08-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (parser, duplicate_parser): Move code out 
	for duplicating an existing parser to a new function.
	* tp/Texinfo/Convert/HTML.pm (output) <renamed nodes>: Call 
	'duplicate_parser'.

2018-08-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%default_parser_state_configuration):
	Remove 'gettext' and 'pgettext'.
	* tp/texi2any.pl ($parser_default_options): Remove 'gettext' and 
	'pgettext'.
	* tp/Texinfo/Parser.pm (%parser_default_configration_subs):
	(%parser_default_configration_no_subs): Remove.  There are no
	subroutines in the parser configuration any more.
	(_setup_parser_default_configuration): Remove.
	(parser, simple_parser): Call dclone directly instead of 
	_setup_parser_default_configuration.  Do not check for CODE 
	values on the parser hash object when duplicating a parser.
	(_setup_conf): Do not check for CODE values on the parser hash 
	object when copying a parser configuration.
	(MODULE DOCUMENTATION SECTION): Remove mention of 'gettext' 
	configuration.
	* tp/Texinfo/Common.pm (warn_unknown_language, warn_unknown_split):
	Do not take a 'gettext' argument.  Callers updated.
	* tp/Texinfo/Report.pm (new): Do not set 'gettext' or 'pgettext' 
	on object.
	* tp/Texinfo/Convert/Converter.pm (converter): Do not set 
	'gettext' or 'pgettext' on object.

2018-08-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (__, __p): Copy functions from 
	texi2any.pl.  Place these in @EXPORT.
	(%default_parser_state_configuration): Refer to __ and __p
	for 'gettext' and 'pgettext' instead of stub functions.
	* t/test_utils.pl: Call Locale::Messages::bindtextdomain for 
	'texinfo' domain as well as 'texinfo_document'.
	* tp/texi2any.pl (__, __p): Remove definitions.

	* tp/Texinfo/Report.pm (__, __p): Do not take a first argument 
	that is a parser object.  Do not look at 'gettext' and 
	'pgettext' configuration values: call the functions in 
	Locale::Messages directly.

	* tp/Texinfo/Common.pm,
	* tp/Texinfo/Structuring.pm,
	* tp/Texinfo/Parser.pm,
	* tp/Texinfo/Convert/Converter.pm,

	* tp/Texinfo/Convert/Info.pm,
	* tp/Texinfo/Convert/Plaintext.pm,
	* tp/Texinfo/Convert/TexinfoXML.pm:
	Do not call __ or __p as methods on a parser object: use the
	functions exported from Common.pm instead.

	The only effect of this change should be in the test suite where 
	the default stub values for 'gettext' and 'pgettext' were used 
	for Texinfo.  This should have no user-visible effect.  The name 
	of the translation domain ("texinfo") is no longer set from the 
	name of the package in texi2any.pl, but this was already 
	hard-coded in Texinfo/Report.pm.

2018-08-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl (test): Avoid method call syntax for 
	calling Texinfo::Parser::parser.

2018-08-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Customization Variables for @-Commands):

	out commands that only do anything for TeX.  Report from Karl.

2018-08-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/HTML.pm (_parse_node_and_warn_external):

2018-08-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%default_parser_state_configuration):
	Do not allow customizing the root parser context.
	* tp/Texinfo/Parser.pm (parser, simple_parser, _parse_texi): 
	Hard-code '_root' as the root context.
	* tp/t/accents.t (test_accent_stack, test_enable_encoding):
	Do not set 'context' on created parser.  Allow for an extra 
	level of element nesting on the tree returned from the parser.

2018-08-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_register_label): Remove a useless

	a value.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

2018-08-07  Vitezslav Crhonek <vcrhonek@redhat.com>  (tiny change)

	leaking memory.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-test.inc (run_ginfo, timeout_test): Record process 
	ID of background process that does the timing out, and kill this 
	process if ginfo exited first.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/infomap.c (default_emacs_like_ea_keys)
	(default_vi_like_ea_keys): Remove ineffectual key bindings.
	Remove key bindings for sequences beginning with ESC, as these 
	have not worked since ESC was made an abort key.  Remove binding 
	for "C-x o" as it is not possible to escape the echo area any 
	more.  Remove bindings for SPC and ? which are self-inserting.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-inter.inc: File removed.  All contents moved into
	Init-test.inc.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-inter.inc (init_interactive_test): New function,
	containing commands that were at the top-level of this file.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-inter.inc (run_ginfo): Run ginfo inside a subshell 
	with parentheses instead of using "sh -c".  This enables the use 
	of "$@" and avoids the need for an extra level of quoting when 
	calling run_ginfo.  Time out the process outside of the 
	subshell.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/echo-area-no-completions.sh: New test.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/echo-area.c, info/session.c (pause_or_input):
	Move to session.c.  Do not pause if there is already buffered 
	input waiting.

2018-08-07  Vitezslav Crhonek <vcrhonek@redhat.com>  (tiny change)

	* info/echo-area.c (info_read_completing_internal): Avoid memory leak.

2018-07-13  Niko Tyni <ntyni@debian.org>  (tiny change)

	Perl 5.28 introduced thread-safe locales, where 'setlocale'
	only affects the locale of the current thread. External code
	like 'mbrtowc' isn't aware of this thread specific locale,
	so we need to explicitly modify the global one instead.
	
	Without this we could enter a busy loop in xspara__add_next
	(Texinfo::Convert::XSParagraph) for UTF-8 documents when mbrtowc
	returned -1.

	* tp/Texinfo/Convert/XSParagraph/xspara.c (xspara_init)
	[Perl version >= 5.28]: Call 'switch_to_global_locale' and 
	'sync_locale'.

2018-07-13  Niko Tyni <ntyni@debian.org>  (tiny change)

	* tp/Texinfo/Parser.pm (_parse_special_misc_command) <@clickstyle>:
	Escape braces in regex to be compatible with recent Perl 
	versions.

2018-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Transformations.pm (_reference_to_arg):
	Refer to 'args' array instead of 'brace_command_contents'.
	(Makes a couple of tests failing since 2017-10-29 pass.)

2018-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/Plaintext.pm (_convert):
	When checking if a node name in a cross-reference includes a
	`.', do not include in the check any manual name that may have 
	already been stored inside the paragraph formatter.  Rical Jasan 
	reported that an error message mentioning the "node name" would 
	be given for output like "(gcc.info)Debugging Options" which is 
	confusing as the `.' is not in the node name "Debugging 
	Options".  (bug-texinfo 2018-02-09)

2018-06-02  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/nodes.c (info_node_of_tag_ext): Always call

	commands could find matches in the node information line if the 
	use set "hide-note-references=On".

	anywhere.

2017-12-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\codequoteright, \codequoteleft): Check if we

        ftp.gwdg.de, www.nano-editor.org, cran.r-project.org, tug.org.
        Update info for avl, flex, myserver, readline.

2017-12-11  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/htmlxref.cnf: Use https instead of http for links to 
	manuals on gnu.org.  Report from Bruno Haible.

2017-12-02  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\resetmathfonts): Define \scriptfont and 
	\scriptscriptfont in addition to \textfont.  Vincent Lefevre 
	reported that @var didn't work in superscript in math mode
	(bug-texinfo, 2017-11-27).

	checking \pagetotal.

2017-11-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\balancecolumns): If it appears that we have
	been called on to balance too much material for the final page 
	of the double column material, output some of it using 
	\doublecolumnout and leave remainder on current page.
	Otherwise, two problems occurred with the output: first, that
	the material on the last page of the index extended too low on 
	the page (see "Final page of index hard to balance" case in
	texinfo-tex-test.texi); and second, a blank page could occur 
	before the final page of the index (report from Arnold Robbins) 
	(this happened because of marks output in \savemarks and 
	\restoremarks).
	
	(\enddoublecolumns): Only change the output routine back to the 
	usual one and reset all the formatting variables if no extra 
	material has been added to the current page.  Otherwise, repeat.

	* doc/texinfo.tex (\pagesizes): Add one inch to height and width 
	so that text will still fit on the page if @pagesizes is used
	with a small width.  Report from Christopher Diemech
	2017-10-12.

2017-10-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi): Remove all calls to
	_register_command_arg that added elements to 
	'brace_command_contents' array.  Look at 'args' instead
	of 'brace_command_contents'.
	(_remove_empty_content_arguments): Do not check for a 
	'brace_command_contents' array.
	(module documentation section): Remove mention of
	brace_command_contents.
	* tp/Texinfo/Report.pm (_substitute): Do not look at
	'brace_command_contents' array.
	* tp/Texinfo/Convert/Converter.pm (_table_item_content_tree):
	Do not call _register_command_arg.

	The effect of this change is to make the parse tree less cyclic,
	which should make it easier to understand, for example when it 
	is printed.  It may also reduce memory use.

2017-10-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/DocBook.pm (_convert):
	Use 'args' array instead of 'brace_command_contents' array.

	elements are defined to avoid creating them accidentally.

2017-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/TexinfoXML.pm (_convert): Replace use
	of 'brace_command_contents' array in the 'extra' hash with
	the 'args' in the main tree.

2017-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_isolate_last_space): For 
	'brace_command_arg' only, save trailing spaces in 
	'spaces_after_argument' extra value instead of adding a 
	'spaces_at_end' element to the main tree.
	* tp/Texinfo/Convert/TexinfoXML.pm (_convert),
	* tp/Texinfo/Convert/Texinfo.pm (_expand_cmd_args_to_texi):
	Update to look at 'spaces_after_argument' after an argument to

	unused.

2017-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/MiscXS/misc.c (xs_abort_empty_line): Update to
	match Perl implementation.
	* tp/Texinfo/Parser.pm (import): Re-enable XS overrides.

2017-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi): Rename reference to spaces 
	element from 'spaces_before_argument' to 'spaces_before_argument_elt'.
	(_abort_empty_line): Replace 'spaces_before_argument_elt' value
	with 'spaces_before_argument', a simple string value.
	(_close_current),
	(_parse_texi) <new line>: Call '_abort_empty_line' to remove 
	spaces element.

	* tp/Texinfo/Convert/Converter.pm
	(_collect_leading_trailing_spaces_arg),
	* tp/Texinfo/Convert/Texinfo.pm (convert, _expand_cmd_args_to_texi),
	* tp/Texinfo/Convert/TexinfoXML.pm (_leading_spaces_before_argument):
	Access 'spaces_before_argument' as a string value.

2017-09-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_abort_empty_line): Change code to
	keep track of which element refers to space element in its
	'extra' hash.  No functional change intended.

2017-09-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_abort_empty_line): Change the name of a 
	variable.  Use a variable to simplify the code.

2017-09-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_abort_empty_line): Remove
	'empty_spaces_before_argument' element from main tree.
	(import): Temporarily disable XS overrides.
	(_parse_texi) <new line>: Remove an 
	'empty_spaces_before_argument' element.
	Otherwise it will not be removed in '_abort_empty_line' because 
	a 'new_line' element is in the way.
	Do not call '_abort_empty_line' for a continuation with @ inside
	a def command, as this leads to an 'empty_spaces_before_argument'
	element being removed when it was not before.
	(close_current) <bracketed>: Remove an 
	'empty_spaces_before_argument' element.  This happens for some 
	cases of malformed input.

	* tp/Texinfo/Convert/Texinfo.pm (convert, _expand_cmd_args_to_texi):
	Check for a 'spaces_before_argument' extra value, and output the 
	spaces in it.
	* tp/Texinfo/Convert/TexinfoXML.pm (_leading_trailing_spaces_arg):
	Call _leading_spaces_before_argument to check for 
	'spaces_before_argument' extra value.
	
	* tp/t/test_tree_copy.t: Disable all tests, temporarily.
	* tp/Texinfo/Convert/Converter.pm
	(_collect_leading_trailing_spaces_arg): Check for 
	'spaces_before_argument' extra value.

	The effect of this change is to make the parse tree less cyclic,
	which should make it easier to understand.

2017-09-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <after ',' separating arguments>:
	Save 'spaces_before_argument' on element corresponding to argument.
	* tp/Texinfo/Convert/TexinfoXML.pm (_convert): Call 
	_leading_spaces_before_argument instead of _leading_spaces_arg.  
	This uses the 'spaces_before_argument' element we saved in 
	'_parse_texi'.

2017-09-22  Mathieu Lirzin  <mthl@gnu.org>

	* Makefile.am (CLEANFILES): Remove $(noinst_SCRIPTS) to
	keep 'pre-inst-env' when doing 'make clean'.

2017-09-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <'{' seen>: Set 
	spaces_before_argument on element for the argument itself, not 
	for the element corresponding to the command, which is the 
	parent element.
	* tp/Texinfo/Convert/TexinfoXML.pm (_convert): Allow 'spaces' 
	attribute to be set for the element output for the first 
	argument to a brace command.
