.IX Title "TEXDOC 1"
.TH TEXDOC 1 "2007-06-05" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
texdoc \- Search for NAME in the TeX documentation and start a viewer.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBtexdoc\fR
[\fB\-h|\-\-help\fR]
[\fB\-v|\-\-verbose\fR]
[\fB\-V|\-\-version\fR]
[\fB\-l|\-\-list\fR]
[\fB\-S|\-\-search\fR]
[\fIname|pattern\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\fBtexdoc\fR is a script which attempts to find and display
documentation for tex files. Without any options, the file
\fBname\fR\fI.ext\fR is displayed, where \fI.ext\fR is one of the
extensions defined in the variable \s-1TEXDOCEXT\s0 in
\&\fBtexmf.cnf\fR. The viewer used for displaying the file can be
customized.
\fBtexdoc\fR accepts compressed files, too. You can also specify the
complete filename, e.g. to decide which of two files with equal
basename you want., In this case, however, access to compressed files
is not possible.
.SH "OPTIONS"
.IP "\fB\-h\fR, \fB\-\-help\fR" 4
Display a usage message
.IP "\fB\-V\fR, \fB\-\-version\fR" 4
Display version information and exit
.IP "\fB\-v\fR, \fB\-\-verbose\fR" 4
verbose mode: show viewer command
.IP "\fB\-l\fR, \fB\-\-list\fR" 4
Just list all files that match \fIname\fR, do not start a viewer.
.IP "\fB\-S\fR, \fB\-\-search\fR \fIpattern\fR" 4
\&\fIpattern\fR is treated as a lua pattern (similar to basic regular
expressions, with `%' as escape character instead of `\\'). The output first lists all
directory names which match \fIpattern\fR and then all files.
Currently, directories without an ls-R file are ignored.
.SH "VARIABLES"
.RS 4
.IP "TEXDOCS = .;$TEXMF/doc//"
Specifies the directories where TeX documentation is stored
.IP "\s-1TEXDOCEXT\s0 = {:.pdf:.ps:.dvi:.txt:.tex}{:.gz:.bz2}:.html" 4
Recognized formats for documentation, the first match wins. The
default uses standard kpathsea brace notation. `html' should be last
in order to prevent the catalogue entry from being shown when other
documentation exists.
.IP "\s-1TEXDOC_VIEWER_\fBFORMAT\fR\s0 = (command %s) &" 4
Defines the viewer to be used for \fBFORMAT\fR,
e.g. \fITEXDOC_VIEWER_DVI\fR. The filename (and tempfile cleanup
commands, if needed after decompression) is substituted for `%s'. If
the viewer does not put itself in the background, the command must be
enclosed in parentheses and the `&' sign appended, as shown in the
example for \fIcommand\fR.
.IP "\s-1TEXDOC_UNZIP_\fBFORMAT\fR\s0 = command -a -c " 4
This variable specifies the command which is used to uncompress a file
compressed as \fBFORMAT\fR. It result must go to \fIstdout\fR.
.IP "\s-1TEXDOC_FORMATS\s0 = pdf,dvi,ps,txt,tex" 4
The formats for which a viewer is defined in \fItexmf.cnf\fR (order
does not matter).
.IP "\s-1TEXDOC_ZIPFORMATS\s0 = gz,bz2" 4
The compression formats for which a decompression command is defined
in \fItexmf.cnf\fR.
.IP "\s-1TEXDOC_RMFILE\s0 = rm -f" 4
The command used to remove a file on the target system. This is used
for temporary files which are needed for viewing compressed documents.
.IP "\s-1TEXDOC_RMDIR\s0 = rmdir" 4
The command used to remove a directory on the target system. This is
used for temporary directories which are needed for viewing compressed
documents.
.SH "BUGS"
Currently no bugs are known, but there are some limitations:
.IP "Specifying the filename, complete with extension"
This doesn't work for compressed files.
.IP manpage
The manpage has been written on a template created by pod2man, and its
source contains a lot of (probably) useless cruft at the beginning.
.SH "HISTORY"
Original version by David Aspinall <da@dcs.ed.ac.uk>
.Sp
Rewritten for use with bash 2 and teTeX under Linux by Simon Wilkinson
<sxw@dcs.ed.ac.uk>
.Sp
Changes for web2c\-7.2 resp. teTeX\-0.9 and portability fixes by
Thomas Esser <te@dbs.uni\-hannover.de>, Jun 14 1998
.Sp
Support for compressed documentation implemented by adopting changes
made by debian. Thomas Esser, Dec. 2004.
.Sp
Rewritten using texlua by Frank Küster <frank@kuesterei.ch>. Changed
the \-s option to use ls-R instead of \fIfind\fR, May/June 2007.
