TkInfo: Stand-alone usage
-------------------------

    (requires the wish shell (Tk version 4.0 or better))

When invoked with no arguments, tkInfo looks for an "info tree" (a
collection of info files installed on your system) and displays the
top level node.  On a well maintained system, you can get to every
info file starting from this top level node.  Alternatively, you can
specify the file and node you want to see on the command line.

Usage: tkinfo [--help] [[-|+]headers] [[-|+]buttons]
              [[-|+]scrollthrough] [[-|+]showdir] [[-|+]pagesep]
              [-linklook type] [-highlight type] [-searchlook type] 
              [-geometry geom] [-display display] [-iconic] 
              [-dir dir1] [-dir dir2] ... [node]
Options:
 --help           Produces this help message.
 -/+headers       Turns on/off display of the raw info node headers.
 -/+buttons       Turns on/off display of the button row.
 -/+balloons      Turns on/off balloonhelp for the buttons.
 -/+scrollthrough Turns on/off going to successor when scrolling through end.
 -/+showdir       Turns on/off showing the full pathname of the info file.
 -/+pagesep       Turns on/off inserting page separators when scrolling.
 -linklook        Specifies how to display xrefs and menu entries.  Must
                  be one of "color", "font", or "underline".
 -highlight       How to highlight links. Can be "color", "underline", or 
                  "inverse".
 -searchlook      How to highlight the matches after searches. Can be "color",
                  "underline", or "inverse".
 -geometry        Geometry of the window. format: XxY+A+B or XxY or +A+B.
                  X,Y specify size in characters, A,B give location in pixels.
 -display         X display to use for the tkInfo window.
 -iconic          Start the first window in iconic state.
 -dir             Specifies a directory to search for info files, in addition 
                  to those contained in the INFOPATH environment variable.
                  Several -dir options can be present; the directories will be
                  searched before INFOPATH, in the order given.
 node	          Specifies the node to visit initially. Possible formats:
                    "(filename)nodename"  most general
                    "(filename)"          equivalent to (filename)Top
                    "filename"            equivalent to (filename).
                  If filename is not absolute, the info directories (from 
                  INFOPATH and -dir) will be searched. If filename cannot be 
                  found, its lower case version will be tried.
                  An alternative way to specify the node "(FILE)NODE" is 
                  with "-file FILE -node NODE".
                  If no node is given, the default "(dir)Top" is used.

Environment variables:
 INFOPATH         A colon (`:') separated list of directories to search
      	          for info files. More directories can be given with -dir 
                  option, above. If not set, TkInfo will try various
                  standard directories that should be ok for most systems.
 INFOSUFFIX	  A colon separated list of file suffixes to try when searching
      	          for an info file. If not set, tkinfo will try the suffixes
                  "", ".info", and "-info". In addition, tkinfo will
                  always automatically try the suffixes .Z, .z, bz2, and .gz
                  and uncompress transparently if necessary.

How to customize tkInfo
-----------------------

The colors, fonts, and geometry of tkInfo can be customized using the
standard X options database. A random example follows. You can either put
(parts of) this in your .Xdefaults or .Xresources file or you can
create a global file /usr/lib/X11/app-defaults/tkinfo that will apply
to all users of your site. To have the new options take effect,
restart your X server or use the program xrdb. More information about
the X options mechanism is available from the X man page. Use tkman
for reading man pages or you lose.

Windows and Mac users can't do this, but they can change the "option" 
lines in the procedure tkiInit in the tkInfo script itself.

Roadmap to the tkInfo source code
---------------------------------

TkInfo is a Tcl/Tk script.  The following information is for people
familiar with Tcl/Tk who want to hack on tkInfo.  You should read the
tkinfo source along with this roadmap.

We keep a global array of variables tki() to store things such as the
current status of the user-toggable options, the current window, list
of all windows, the mouse position at button-press events, and the
extracted information of already parsed info files (including their
full node text, see below). We also have a global array of variables
for every toplevel window; the array has the same name as the window
and is usually called wvars() through a call to upvar. We use wvars() to
store displayed status messages, the name of the displayed node, the
list of previously visited nodes, the string being searched for etc.

The widget tree looks like this: the toplevel windows are called
.tki1, .tki2, etc. .tki1.bar is the menubar with buttons .file, .node,
.search, .options, and .help. The associated menus are called
.tki1.bar.file.m and so on. The main text window is called
.tki1.main.text and its scrollbar is .tki1.main.vsb. Then there is the
the button row .tki1.buts with buttons .next, .prev, .up, and .last
and the status line .tki1.s with filename window .tki1.s.filename and
status message .tki1.s.status. If the user is prompted for an input,
.tki1.s.filename contains the prompt and .tki1.s.input is the entry
area.  Then there is the pop-up menu .tki1.transientmenu which appears
on Button-3.


tkInfo requires the following global variables:
 tki		This is a huge array where all the loaded info-files
		are stored.  It also contains some configuration state.
		The contents of this is described below.
 .tki##		Each toplevel info window has a global variable associated
		with it.  The name of the variable is the same as the
		toplevel window name, which is ".tki" followed by some number.
 tkiEmbed	tkInfo can operate stand-alone (like the "info" program) or
		embedded (part of your application).  Embedded mode is
		used iff this variable exists.  When this file is
		sourced in the stand-alone case, the argv options will be
		parsed (see tkiBoot() below) and a new toplevel window
	 	will be opened.


tkInfo may be used in one of three modes: stand alone, embedded or
as a server tool.  These modes are described below:

Stand-alone
	In this mode, the user directly invokes tkinfo, and directly
	manipulates it to display the nodes of interest. This mode
	requires that the shell script "tkinfo" be properly
	configured, and that the info path be properly configured,
	either by editing the default info path in "tkinfo"/tkiInit(),
	or by the user's INFOPATH environment variable. The built-in
	help contains additional information (command line arguments)
	for this mode.

Embedded
	In this mode, your application will include tkinfo as part of
	its distribution, and tkinfo will run within the same process
	and the the same TCL interpreter as your application.  tkInfo
	is written with this in mind, and avoids name space pollution.
	In this mode, tkInfo doesn't do anything until the application
	explicitly request an action by calling tkiWinShow(); normally
	the application will do this in response to the user selecting
	a "Help" button or pressing a "Help" key.

	To use this mode, your application must set the global variable
	``tkiEmbed'' to any value and then source "tkinfo" (the
	auto-load facility may replace explicitly source'ing
	"tkinfo", but ``tkiEmbed'' must be set before this
	happens). 

	tkiAddInfoPaths() should be called by the application to let
	tkInfo know where the application's info files are installed.
	The application should call tkiWinShow() to display a window.
	Also, the application may find tkiWinContextHelp() useful
	for processing "Help" key bindings.

Server Tool
	From the user's perspective, this is very similar to the
	Embedded mode, but the implementation is different.  In this
	mode, tkInfo runs as in the stand-alone mode, but responds to
	requests from other applications via Tk's "send" mechanism.
	The application must rendezvous with tkInfo (locating the
	existing server or starting a new server running) and makes
	calls to tkiAddInfoPaths() and tkiWinShow() as in the embedded
	case (but via "send").  The application may wish tkInfo to
	dedicate a single window to the application, the "window tag"
	feature of tkiWinShow() may be useful for this.


The core structure of an info file is a {node}.  Each info file
consists of a set of nodes separated by a magic character.  Each nodes
consists of of a headerline and a body, which can contain a menu.
There are also special nodes that contain control information used to
reference "split" files and speed up access.  A node may be specified
in one of several ways (called a {nodeSpec}):
	(filename)nodename      Explicit.
	nodename		The given node within the current file.
	(filename)		The "Top" node of the file.
If a filename can't be found, we try the lower case version; if a nodename 
can't be found we try case insensitive match.

In the implementation below, the info format consists of {nodes} stored 
in files.  A given info file has three identifiers associated with it:
 -	The {filename}, which is the name used either by the user to
	reference a file, or by one info file to reference another.
	Such a reference could be complete UNIX path name (either
	absolute or relative), or may be a partial specification (see below).
 -	The {filepath}, which is a valid UNIX path name to access the
	file.  The filepath is derived from the filename.  If the filename
	is already a valid path, no work needs be done.  Otherwise,
	the filepath is formed by prepending a path prefix and appending
	a file suffix.  These are defined by the INFOPATH and INFOSUFFIX
	variables.
 -	The {filekey}, which is an internal, auto-generated token associated
	with each file.
A typical (filename,filepath,filekey) would be 
(emacs-2,/usr/info/emacs-2.gz,fk3). This file has the info file called "emacs" 
as a parent.

The global array "tki" contains the following elements about the
already parsed files:
  fileKeys-$fileName	The fileKeys for $fileName. If there are info files 
                        of the same name in different directories, they will 
                        get differnet fileKeys.
  fileinfo-$fileKey	The fileinfo struct for $fileKey. Each fileinfo is
			{ fileKey fileName filePath pntKey }
                        pntKey is the filekey of the parent, or the empty
                        list if there is no parent.
  incore-$fileKey	Boolean 0/1; true if file has been loaded into core.
  nodesinfo-$fileKey	A list of nodeinfo for every node in $fileKey.
			Each nodeinfo is a list { idx node file up prev next }.
                        Node, file, up, prev, next are the names given
                        in the info node's first line.
  nodesbody-$fileKey	A list of the textual body for every node in $fileKey.
                        The nodes are given in the same order as in nodesinfo.
  indirf-$fileKey	List of indirect-file-info for $fileKey.  Each
			info is a list { indirFileKey byteOfs }.
  indirn-$fileKey	List of indirect-node-info for $fileKey.  Each
			info is a list { nodeName byteOfs fileKey }.
  xrefinfo-$fileKey-$nodeIdx
			A list of all cross reference
			pointers within the node body's text. Every element
                        has the form { idx toNode stpos endpos label } 
                        stpos and endpos give the position of the link in 
                        the text.
  menuinfo-$fileKey-$nodeIdx
			Contains information on all menu entries
			within the node's menu text.  Consists of list of:
			 { linecnt menucnt toNode nBeg nEnd menutxt }
                        nBeg and nEnd give the positions of the menu entry
                        in its line.

Notes (some important, some not).
1.	Because of the graphical system, there may be several parallel
	info windows active.  These windows must operate independently.
	Because of this, there can be no concept of the "current file"
	or "current node" within the tkinfo core.  Rather, this information
	must be maintained by the window.
2.	Because of #1, we must maintain multiple files in core.  Currently
	we never flush.
3.	The background color used in tkiInit() is BISQUE1, from tk/defaults.h
4.	The byte offsets in the indirect tables are not used as such;
	this is because we parse the file when loaded.  However, they are
	used to identify which indirect file the node is in.
5.	The function tkiLoadFile() attempts to deal with compressed files.
	Currently it uses "zcat" for .Z files, "bunzip2 -c" for .bz2
        and "gunzip -c" for .z and .gz files.
	If you have better suggestions, please let me know.


Here are descriptions of the more important procedures:

tkiInit 
   Initializes the default INFOPATH and other global variables such as
   the default geometry, link color, cursor etc.  It also sets the
   regular expression used for parsing info files by calling
   _tkiNodeParseInit and sets up the builtin info pages by calling
   _tkiBuiltinFile (which does its job by setting up the relevant
   tki() variables so that it looks like tkInfo has actually parsed
   the builtin info "files").

tkiTimeStatus
   takes a script as argument, executes it, and prints the time it
   took on stdout. This can be used to profile tkinfo if the option
   "Time Status" is enabled from the option menu. Several crucial
   calls are wrapped in a tkiTimeStatus.

tkiInfoWindow
   Accepts the same arguments as tkinfo. It first parses the options
   using topgetopt, processes them, and then calls tkiWinShow to
   actually create the new window and display the node.

tkiWinShow
   The main entry point: takes the specification of an info node and a
   window, creates that window if necessary, and displays the
   node. This is also suitable for being called from other tcl
   programs via send.

tkiWinCreate
   creates a toplevel window with all its subwindows. Also initializes
   the winfo() variables for that window. Creates all bindings except
   those for the main text window which are handled by _tkiWinBind.

_tkiWinBind
   Creates all the bindings for the text window and search entry
   boxes. Many of these bindings are created automatically via
   _tkiBindAccels from the accelerators of the various menu
   entries. If you have bindings to add, here's the place.

_tkiWinAction
   The central manager of all actions that can be performed by the user
   on a window, such as quitting, scrolling, searching, and moving to
   other nodes. The actions themselves are actually handled by other
   procedures.  This function is designed to be bound to various
   events.

_tkiWinPromptMap
   Brings up the lower prompt area for searches etc.

_tkiWinPromptOk
   Is called when the user presses Enter in the lower prompt area. It
   takes the appropriate action and unmaps the prompt area using 
   _tkiWinPromptUnmap. 

tkiWinDpy
   Inserts a node into the current text window, complete with
   tags. Updates the history and last lists. The actual parsing is
   done in tkiNodeParseBody. Also updates the Next/Previous/Last
   button bindings and enables/disables menu entries as appropriate
   for the displayed node.

tkiWinContextHelp
   helper function for the case where tkinfo is embedded in a larger
   application. The app can associate an infonode spec to every major
   window, and this function will display the associated node in a new
   tkinfo window.

tkiFileGet
   loads a file into memory and returns the filekey using tkiFileFind
   and tkiFileLoad.

tkiFileFind
   returns the full filename of a partially specified info file using
   the list of info directories and info suffixes and compression
   suffixes.

tkiFileLoad
   loads an info file and parses its nodes using tkiFileParseNode in
   order to fill up the respective entries in tki(). tkiFileParseNode
   has to deal with tag tables (which describe where in a file a node
   is located) and indirect tables which point to other info files.

tkiGetNodeRef
   locates an info node wherever it is; loads the info file if
   necessary. Info files can be split; for example, emacs.info is only
   a short table containing pointers to the info files emacs-1 to
   emacs-29. This is called an "Indirect" table, and emacs.info is
   called the parent of the other emacs info files. tkiGetNodeRef
   deals with this mess transparently, calling itself recursively on a
   child if necessary.

tkiNodeParseBody
   parses the body of a node to locate all crossreferences, and
   returns a list of them and stores it in tki().

tkiNodeParseMenu
   parses the body of a node to locate all menu entries, and returns a
   list of them and stores it in tki().

_tkiWinManPage
   displays a man page in a tkman window. Either starts a new tkman or
   contacts an existing one. Communication is via the tcl send
   mechanism. This does not work if you X server is insecure; use xdm
   to get a secure session.

_tkiBindAccels
   a nice utility function to support accelerator keys in menus.

searchboxSearch and searchboxNext
   support for searching, regexp or normal, ready to be bound to
   events.

TextSearch and regexpTextSearch
   used by the searchbox functions to locate all matching strings in a
   text window and to apply a given tag to them.

About tkInfo
============

This is tkInfo version $tki_version, built on \$Date: 2004/03/22 23:53:57 $.
TkInfo is a browser for documentation in the info file format.

The versions of tkInfo up to 0.7-beta were written by Kennard White
(kennard@ohm.eecs.Berkeley.EDU).  You can obtain the tkInfo
distribution up to version 0.7-beta by anonymous ftp from:

	ftp://ptolemy.eecs.berkeley.edu/pub/misc

Axel Boldt (axelboldt@yahoo.com) adapted tkInfo in 1997 for newer
tcl/tk versions and added some features. The versions 0.8 and later
can be gotten from http://math-www.uni-paderborn.de/~axel/tkinfo/

Version 2.6 is needed for Tcl/Tk 8.4 and higher.

Please report any and all problems, fixes, and suggestions to

Info Files
==========


tkInfo is a browser for "info" files, a file format that supports a
robust hypertext system which is ideal for on-line help.  

Each info file consists of several "nodes", units of information that
can contain crossreferences to other nodes. TkInfo displays one node
per window at a time, and highlights the crossreferences.

The entry point and top most node of an info file is usually called
"Top" and contains the table of contents for the info file. Many
nodes, including Top, contain menus pointing to subnodes, thus
creating a tree of nodes. The subnodes specify their parent as their
"up node". Furthermore, most nodes specify a "next node" and a
"previous node" on the same level, and this yields a convenient way to
traverse the tree.

The top-level info file is called "dir" and contains only a single
node "Top" which is a directory listing all the other info files on
your system. This is where tkInfo starts out by default.

GNU programs such as the editor emacs, the compiler gcc and the shell
bash are documented in the texinfo format, which can be transformed
into info files using the makeinfo program. It is also possible to
print out high quality hardcopies from texinfo sources via the TeX
system.

Ctrl-s  Continue previous search forward.
r,\     Search backwards, literally resp. by regular expression.
Ctrl-r  Continue previous search backward.


Scrolling
---------

b, HOME, <			Jump to the beginning of the node.
e, END,  >			Jump to the end of the node.
SPACE, Ctrl-f, Ctrl-v, PgDn	Scroll down one page. If at end of node,
                                jump to logical successor node.
DEL, Ctrl-b, Alt-v, PgUp        Scroll up one page. If at beginning
                                of node, jump to logical predecessor node.
Crsr DOWN, j, Ctrl-n		Scroll down one line.
Crsr UP, k, Ctrl-p		Scroll up one line.
Ctrl-m				Jump to beginning of current node's menu.

Usage Tips for TkInfo
=====================


Next, Previous, Last and Back
-----------------------------

The most important thing to understand is the function of the "Next"
and "Previous" buttons. They have nothing to do with netscape's "Back"
and "Forward" buttons. Rather, every info node specifies a "next node"
and a "previous node" in its first line, and the "Next" and "Previous"
buttons simply jump there. Most info files are organized in such a
fashion that the next node is on the same hierarchical level as the
current one, so that all menu entries of the current node are skipped
when you click on "Next". Think of nodes as pages of a book: "Next"
jumps from one section's title page to the next section's title page
(which need not be the immediately following page). That's why
continually hitting "Next" will generally NOT visit all the nodes of
an info file in order. If you want to do that, simply keep hitting
Space, or choose "Logical Successor" from the popup menu that's bound
to the right mouse button.

If you want to go to wherever you were before, use the "Last" button
or the History menu. This is the functional equivalent to netscape's
"Back".


Redirection Windows
-------------------

If you do not want to visit all nodes in order, you have to navigate
through the menus by clicking on entries. This can become confusing,
unless you make use of the middle and right mouse buttons. Clicking on
a link with the middle button will bring up that node in a new
window. This comes handy when you quickly want to check out a cross
reference that would only distract if brought up in the main window.

Clicking on a link with the right button creates a "redirection
window" for the current window and displays the node there. If you
continue to use the right button in the current window, the output
will also be sent to that redirection window. Every window (even
redirection windows) can have one redirection window associated with
them in this manner. This is nice because it avoids too many tkinfo
windows cluttering up your desktop and it is useful when browsing
through large menus: I usually keep the menu visible in one main
window and explore the interesting menu entries in its redirection
window, which I place right next to the main window.


Top and Dir
-----------

"Top" is the topmost node of the current info file and will usually
contain the table of contents. The "Top" nodes of bigger info files
often contain a detailed node listing following the menu of immediate
subnodes. This way, you can access every node of the info file with a
single click and there's no need to navigate the hierarchy at all.

"Dir" is the toplevel info file which contains a listing and short
description of all the installed info files on the system. Some
systems have several Dir files because they store their info files in
several directories; if tkInfo knows about these, they will show up
under the Directories Menu entry.


Working quickly, with and without the mouse
-------------------------------------------

Don't forget that you can scroll the current window by dragging with
the middle button. I think this is more comfortable than using the
scrollbar. The mouse bindings are designed so that most functions of
the program can be used easily with one hand on the mouse, and without
much need for the other hand or for mouse movements (right-click
brings up a popup menu).

If you are more of a keyboard person, get used to TAB, Shift-Tab, and
RET to walk through a menu and to select a link. Also, selecting the
forth menu entry for instance is most quickly done by simply hitting
`4'.

If you like working efficiently, you should try TkMan for reading unix
manpages.


Searching
---------

When prompted for a string in the input box below, remember that you
can recall the previous inputs with the cursor UP key. If a search
takes too long, you can interrupt it with Ctrl-g. The search will
start at the beginning of the current node and will wrap around to the
beginning of the info file if you continue to hit Ctrl-s. You can
always jump back to the last match with Ctrl-r.

Instead of doing a full-text search of the whole info file with `s',
it's usually better to start with an index lookup (`i'), which will
try to locate the term in the index nodes and then jump to the
relevant nodes explaining the term. If you want to browse through the
full index, hit `i RET'.


Printing
--------

If you feel the urge to print out an info file, don't. Rather, get
your hands on the corresponding texinfo source and print that one
using the TeX system. The output is much prettier. Info files are not
meant to be printed, and that's why tkInfo doesn't have a print
option.


Info Tutorial
-------------

There is a GNU program called "info" that is similar to tkInfo, but
completely text based.  A tutorial info file written for this program
is available on most systems.  This tutorial is useful if you want to
learn tkInfo's accelerator keys, since the keybindings of tkInfo and
info are almost identical. It will also tell you more about info files
in general. To see this tutorial, select the menu entry below.

# The following material was formerly contained in topgetopt.tcl:

#
# The function has "top" prefix b/c it is conceptually part of my "top" library.
#
# Authors: Kennard White (kennard@ohm.eecs.berkeley.edu)
#	   Phil Lapsley (phil@ohm.eecs.berkeley.edu)
#
# Based on "@(#)getopt.tcl 1.5 12/7/91" by Phil Lapsley
#

# Simple "getopt" for TCL.
#
# topgetopt ?-any? ?-all? opt_list arg_list
# The proc will process the arguments in {arg_list} according to the
# information in {opt_list}.  Processed arguments are passed back
# to the caller by setting variables in the caller's proc-environment
# (i.e., using upvar).
#
# option_list is a list of option specs.  Each spec is a 3-tuple:
#	{ optname varname mode }
# optname is the name of the option to be parsed (without the leading dash).
# varname is the name of a tcl variable in the caller's environment.
#	If ommitted, the varname defaults to the optname.
# mode describes the type of option. If ommitted, it defaults to "single".
#	The modes:
# 	  single:	sets the variable to the next argument.
# 	  append:	lappends the next argument to the variable.
#			this allows multiple instances of the same option.
#	  boolean:	sets the variable to 0 if the argument prefix is "+"
#			 and to 1 of the argument prefix is "-".
#
# "topgetopt" sets the variables named in the option_list that were
# specified in arg_list, and returns the remainder of arg_list after
# the first non "-" or "+" option.  If a bad option specifier is
# encountered, scanning stops and getopt aborts using error.
#
# If -all is specified, then everything in arg_list must match an
# option in opt_list; that is, there may be no "leftover" arguments.
#
# If -any is specified, then processing will stop at the first
# unmatched option.  That is, the returned list of unprocessed
# arguments may contain unregcognized options.
#
# For example, the option_list:
#
#	{ min max { file filename } { toplevel toplevel boolean } }
#
# means that the option "-min value" or "-max value" should set the
# variables "min" or "max" to the specified value, and "-file foo.txt"
# should set the variable "filename" to foo.txt.  "toplevel"
# sets the variable "toplevel", and is a boolean:  the option "-toplevel"
# would set the variable "toplevel" to 1, while the option "+toplevel"
# would set the variable "toplevel" to 0.
#
# In typical usage, the caller will first initialize all the option
# variables to default values, and then call topgetopt.
