</PRE>
<H2>DESCRIPTION</H2><PRE>
<STRONG>infocmp</STRONG> can be used to compare a binary <STRONG>terminfo</STRONG> entry
with other terminfo entries, rewrite a <STRONG>terminfo</STRONG> descrip-
tion to take advantage of the <STRONG>use=</STRONG> terminfo field, or
print out a <STRONG>terminfo</STRONG> description from the binary file
(<STRONG>term</STRONG>) in a variety of formats. In all cases, the boolean
fields will be printed first, followed by the numeric
fields, followed by the string fields.
<STRONG>Default</STRONG> <STRONG>Options</STRONG>
If no options are specified and zero or one <EM>termnames</EM> are
specified, the <STRONG>-I</STRONG> option will be assumed. If more than
one <EM>termname</EM> is specified, the <STRONG>-d</STRONG> option will be assumed.
<STRONG>Comparison</STRONG> <STRONG>Options</STRONG> <STRONG>[-d]</STRONG> <STRONG>[-c]</STRONG> <STRONG>[-n]</STRONG>
<STRONG>infocmp</STRONG> compares the <STRONG>terminfo</STRONG> description of the first
terminal <EM>termname</EM> with each of the descriptions given by
the entries for the other terminal's <EM>termnames</EM>. If a
capability is defined for only one of the terminals, the
value returned will depend on the type of the capability:
<STRONG>F</STRONG> for boolean variables, <STRONG>-1</STRONG> for integer variables, and
<STRONG>NULL</STRONG> for string variables.
The <STRONG>-d</STRONG> option produces a list of each capability that is
different between two entries. This option is useful to
show the difference between two entries, created by dif-
ferent people, for the same or similar terminals.
The <STRONG>-c</STRONG> option produces a list of each capability that is
common between two entries. Capabilities that are not set
are ignored. This option can be used as a quick check to
see if the <STRONG>-u</STRONG> option is worth using.
The <STRONG>-n</STRONG> option produces a list of each capability that is
in neither entry. If no <EM>termnames</EM> are given, the environ-
ment variable <STRONG>TERM</STRONG> will be used for both of the <EM>termnames</EM>.
This can be used as a quick check to see if anything was
left out of a description.
<STRONG>Source</STRONG> <STRONG>Listing</STRONG> <STRONG>Options</STRONG> <STRONG>[-I]</STRONG> <STRONG>[-L]</STRONG> <STRONG>[-C]</STRONG> <STRONG>[-r]</STRONG>
The <STRONG>-I</STRONG>, <STRONG>-L</STRONG>, and <STRONG>-C</STRONG> options will produce a source listing
for each terminal named.
<STRONG>-I</STRONG> use the <STRONG>terminfo</STRONG> names
<STRONG>-L</STRONG> use the long C variable name listed in <<STRONG>term.h</STRONG>>
<STRONG>-C</STRONG> use the <STRONG>termcap</STRONG> names
<STRONG>-r</STRONG> when using <STRONG>-C</STRONG>, put out all capabilities in <STRONG>termcap</STRONG> form
If no <EM>termnames</EM> are given, the environment variable <STRONG>TERM</STRONG>
will be used for the terminal name.
The source produced by the <STRONG>-C</STRONG> option may be used directly
as a <STRONG>termcap</STRONG> entry, but not all parameterized strings can
be changed to the <STRONG>termcap</STRONG> format. <STRONG>infocmp</STRONG> will attempt to
convert most of the parameterized information, and any-
thing not converted will be plainly marked in the output
and commented out. These should be edited by hand.
All padding information for strings will be collected
together and placed at the beginning of the string where
<STRONG>termcap</STRONG> expects it. Mandatory padding (padding informa-
tion with a trailing '/') will become optional.
All <STRONG>termcap</STRONG> variables no longer supported by <STRONG>terminfo</STRONG>, but
which are derivable from other <STRONG>terminfo</STRONG> variables, will be
output. Not all <STRONG>terminfo</STRONG> capabilities will be translated;
only those variables which were part of <STRONG>termcap</STRONG> will nor-
mally be output. Specifying the <STRONG>-r</STRONG> option will take off
this restriction, allowing all capabilities to be output
in <EM>termcap</EM> form.
Note that because padding is collected to the beginning of
the capability, not all capabilities are output. Manda-
tory padding is not supported. Because <STRONG>termcap</STRONG> strings
are not as flexible, it is not always possible to convert
a <STRONG>terminfo</STRONG> string capability into an equivalent <STRONG>termcap</STRONG>
format. A subsequent conversion of the <STRONG>termcap</STRONG> file back
into <STRONG>terminfo</STRONG> format will not necessarily reproduce the
original <STRONG>terminfo</STRONG> source.
Some common <STRONG>terminfo</STRONG> parameter sequences, their <STRONG>termcap</STRONG>
equivalents, and some terminal types which commonly have
such sequences, are:
<STRONG>terminfo</STRONG> <STRONG>termcap</STRONG> Representative Terminals
---------------------------------------------------------------
<STRONG>%p1%c</STRONG> <STRONG>%.</STRONG> adm
<STRONG>%p1%d</STRONG> <STRONG>%d</STRONG> hp, ANSI standard, vt100
<STRONG>%p1%'x'%+%c</STRONG> <STRONG>%+x</STRONG> concept
<STRONG>%i</STRONG> <STRONG>%i</STRONG>q ANSI standard, vt100
<STRONG>%p1%?%'x'%>%t%p1%'y'%+%;</STRONG> <STRONG>%>xy</STRONG> concept
<STRONG>%p2</STRONG> is printed before <STRONG>%p1</STRONG> <STRONG>%r</STRONG> hp
<STRONG>Use=</STRONG> <STRONG>Option</STRONG> <STRONG>[-u]</STRONG>
The <STRONG>-u</STRONG> option produces a <STRONG>terminfo</STRONG> source description of
the first terminal <EM>termname</EM> which is relative to the sum
of the descriptions given by the entries for the other
terminals <EM>termnames</EM>. It does this by analyzing the dif-
ferences between the first <EM>termname</EM> and the other
<EM>termnames</EM> and producing a description with <STRONG>use=</STRONG> fields for
the other terminals. In this manner, it is possible to
retrofit generic terminfo entries into a terminal's
description. Or, if two similar terminals exist, but were
coded at different times or by different people so that
each description is a full description, using <STRONG>infocmp</STRONG> will
show what can be done to change one description to be rel-
ative to the other.
A capability will get printed with an at-sign (@) if it no
longer exists in the first <EM>termname</EM>, but one of the other
<EM>termname</EM> entries contains a value for it. A capability's
value gets printed if the value in the first <EM>termname</EM> is
not found in any of the other <EM>termname</EM> entries, or if the
first of the other <EM>termname</EM> entries that has this capabil-
ity gives a different value for the capability than that
in the first <EM>termname</EM>.
The order of the other <EM>termname</EM> entries is significant.
Since the terminfo compiler <STRONG>tic</STRONG> does a left-to-right scan
of the capabilities, specifying two <STRONG>use=</STRONG> entries that con-
tain differing entries for the same capabilities will pro-
duce different results depending on the order that the
entries are given in. <STRONG>infocmp</STRONG> will flag any such incon-
sistencies between the other <EM>termname</EM> entries as they are
found.
Alternatively, specifying a capability <EM>after</EM> a <STRONG>use=</STRONG> entry
that contains that capability will cause the second speci-
fication to be ignored. Using <STRONG>infocmp</STRONG> to recreate a
description can be a useful check to make sure that every-
thing was specified correctly in the original source
description.
Another error that does not cause incorrect compiled
files, but will slow down the compilation time, is speci-
fying extra <STRONG>use=</STRONG> fields that are superfluous. <STRONG>infocmp</STRONG>
will flag any other <EM>termname</EM> <EM>use=</EM> fields that were not
needed.
<STRONG>Changing</STRONG> <STRONG>Databases</STRONG> <STRONG>[-A</STRONG> <EM>directory</EM>] [-B <EM>directory</EM>]
The location of the compiled <STRONG>terminfo</STRONG> database is taken
from the environment variable <STRONG>TERMINFO</STRONG> . If the variable
is not defined, or the terminal is not found in that loca-
tion, the system <STRONG>terminfo</STRONG> database, in <STRONG>/usr/share/ter-</STRONG>
<STRONG>minfo</STRONG>, will be used. The options <STRONG>-A</STRONG> and <STRONG>-B</STRONG> may be used to
override this location. The <STRONG>-A</STRONG> option will set <STRONG>TERMINFO</STRONG>
for the first <EM>termname</EM> and the <STRONG>-B</STRONG> option will set <STRONG>TERMINFO</STRONG>
for the other <EM>termnames</EM>. With this, it is possible to
compare descriptions for a terminal with the same name
located in two different databases. This is useful for
comparing descriptions for the same terminal created by
different people.
<STRONG>Other</STRONG> <STRONG>Options</STRONG>
<STRONG>-1</STRONG> causes the fields to be printed out one to a line.
Otherwise, the fields will be printed several to a
line to a maximum width of 60 characters.
<STRONG>-a</STRONG> tells <STRONG>infocmp</STRONG> to retain commented-out capabilities
rather than discarding them. Capabilities are com-
mented by prefixing them with a period.
<STRONG>-E</STRONG> Dump the capabilities of the given terminal as
tables, needed in the C initializer for a TERMTYPE
structure (the terminal capability structure in the
<STRONG><term.h></STRONG>). This option is useful for preparing ver-
sions of the curses library hardwired for a given
terminal type. The tables are all declared static,
and are named according to the type and the name of
the corresponding terminal entry.
Before ncurses 5.0, the split between the <STRONG>-e</STRONG> and <STRONG>-E</STRONG>
options was not needed; but support for extended
names required making the arrays of terminal capabil-
ities separate from the TERMTYPE structure.
<STRONG>-e</STRONG> Dump the capabilities of the given terminal as a C
initializer for a TERMTYPE structure (the terminal
capability structure in the <STRONG><term.h></STRONG>). This option
is useful for preparing versions of the curses
library hardwired for a given terminal type.
<STRONG>-F</STRONG> compare terminfo files. This assumes that two fol-
lowing arguments are filenames. The files are
searched for pairwise matches between entries, with
two entries considered to match if any of their names
do. The report printed to standard output lists
entries with no matches in the other file, and
entries with more than one match. For entries with
exactly one match it includes a difference report.
Normally, to reduce the volume of the report, use
references are not resolved before looking for dif-
ferences, but resolution can be forced by also speci-
fying <STRONG>-r</STRONG>.
<STRONG>-f</STRONG> Display complex terminfo strings which contain
if/then/else/endif expressions indented for readabil-
ity.
<STRONG>-G</STRONG> Display constant literals in decimal form rather than
their character equivalents.
<STRONG>-g</STRONG> Display constant character literals in quoted form
rather than their decimal equivalents.
<STRONG>-i</STRONG> Analyze the initialization (<STRONG>is1</STRONG>, <STRONG>is2</STRONG>, <STRONG>is3</STRONG>), and reset
(<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>), strings in the entry. For each
string, the code tries to analyze it into actions in
terms of the other capabilities in the entry, certain
X3.64/ISO 6429/ECMA-48 capabilities, and certain DEC
VT-series private modes (the set of recognized spe-
cial sequences has been selected for completeness
over the existing terminfo database). Each report
line consists of the capability name, followed by a
colon and space, followed by a printable expansion of
the capability string with sections matching recog-
nized actions translated into {}-bracketed descrip-
tions. Here is a list of the DEC/ANSI special
sequences recognized:
Action Meaning
-----------------------------------------
RIS full reset
SC save cursor
RC restore cursor
LL home-down
RSR reset scroll region
ISO DEC G0 enable DEC graphics for G0
ISO UK G0 enable UK chars for G0
ISO US G0 enable US chars for G0
ISO DEC G1 enable DEC graphics for G1
ISO UK G1 enable UK chars for G1
ISO US G1 enable US chars for G1
DECPAM application keypad mode
DECPNM normal keypad mode
DECANSI enter ANSI mode
DEC[+-]CKM application cursor keys
DEC[+-]ANM set VT52 mode
DEC[+-]COLM 132-column mode
DEC[+-]SCLM smooth scroll
DEC[+-]SCNM reverse video mode
DEC[+-]OM origin mode
DEC[+-]AWM wraparound mode
DEC[+-]ARM auto-repeat mode
It also recognizes a SGR action corresponding to
ANSI/ISO 6429/ECMA Set Graphics Rendition, with the
values NORMAL, BOLD, UNDERLINE, BLINK, and REVERSE.
All but NORMAL may be prefixed with `+' (turn on) or
`-' (turn off).
An SGR0 designates an empty highlight sequence
(equivalent to {SGR:NORMAL}).
<STRONG>-l</STRONG> Set output format to terminfo.
<STRONG>-p</STRONG> Ignore padding specifications when comparing strings.
<STRONG>-q</STRONG> Make the comparison listing shorter by omitting sub-
headings, and using "-" for absent capabilities, "@"
for canceled rather than "NULL".
<STRONG>-R</STRONG><EM>subset</EM>
Restrict output to a given subset. This option is
for use with archaic versions of terminfo like those
on SVr1, Ultrix, or HP/UX that do not support the
full set of SVR4/XSI Curses terminfo; and variants
such as AIX that have their own extensions incompati-
ble with SVr4/XSI. Available terminfo subsets are
"SVr1", "Ultrix", "HP", and "AIX"; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>
for details. You can also choose the subset "BSD"
which selects only capabilities with termcap equiva-
lents recognized by 4.4BSD.
<STRONG>-s</STRONG> <EM>[d|i|l|c]</EM>
The <STRONG>-s</STRONG> option sorts the fields within each type
according to the argument below:
<STRONG>d</STRONG> leave fields in the order that they are stored
in the <EM>terminfo</EM> database.
<STRONG>i</STRONG> sort by <EM>terminfo</EM> name.
<STRONG>l</STRONG> sort by the long C variable name.
<STRONG>c</STRONG> sort by the <EM>termcap</EM> name.
If the <STRONG>-s</STRONG> option is not given, the fields printed out
will be sorted alphabetically by the <STRONG>terminfo</STRONG> name
within each type, except in the case of the <STRONG>-C</STRONG> or the
<STRONG>-L</STRONG> options, which cause the sorting to be done by the
<STRONG>termcap</STRONG> name or the long C variable name, respec-
tively.
<STRONG>-T</STRONG> eliminates size-restrictions on the generated text.
This is mainly useful for testing and analysis, since
the compiled descriptions are limited (e.g., 1023 for
termcap, 4096 for terminfo).
<STRONG>-t</STRONG> tells <STRONG>tic</STRONG> to discard commented-out capabilities.
Normally when translating from terminfo to termcap,
untranslatable capabilities are commented-out.
<STRONG>-V</STRONG> reports the version of ncurses which was used in this
program, and exits.
<STRONG>-v</STRONG> <EM>n</EM> prints out tracing information on standard error as
the program runs. Higher values of n induce greater
verbosity.
<STRONG>-w</STRONG> <EM>width</EM>
changes the output to <EM>width</EM> characters.
