.IX Title "TEXDIFF 1"
.TH TEXDIFF 1 "2009-09-24" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
\&\fBtexdiff\fR \- Compares two (La)TeX documents to create a merged version showing changes, similar to that of 'Change Tracking' in some word processors.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
texdiff [\-\-nofloats|\-n] old.tex new.tex [diff.tex]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The first two files are compared and a new TeX file is output. When
the output file is processed with (La)TeX it marks new changes with
blue and old text with red with a strike-through line. Furthermore,
passages with changes are marked at the margin with grey bars by the
LaTeX \f(CW\*(C`changebar\*(C'\fR package (although only after running \f(CW\*(C`dvips\*(C'\fR, in
\&\f(CW\*(C`xdvi\*(C'\fR the bars are one inch too far left to compensate the one inch
offset inserted by TeX printer drivers).
.PP
\&\f(CW\*(C`texdiff\*(C'\fR uses and therefore requires the \f(CW\*(C`wdiff\*(C'\fR command to insert
these marks. If LaTeX macros are included in those striked out or
underlined passages, the latex run will most likely fail. The source
of most problems lies in \f(CW\*(C`wdiff\*(C'\fR tearing apart pairs of
braces. Therefore \f(CW\*(C`texdiff\*(C'\fR is a perl script that calls \f(CW\*(C`wdiff\*(C'\fR internally
and fixes \f(CW\*(C`wdiff\*(C'\fR's output by re-pairing braces again and handling some
commonly used LaTeX macros.
.PP
For texdiff to work, the following LaTeX code must be inserted in the
preamble of the LaTeX document:
.PP
.Vb 3
\& \eusepackage{xcolor} \eusepackage{ulem} \eusepackage{changebar}
\& \enewcommand\eTLSins[1]{\ecbstart{}\etextcolor{ins}{\euline{#1}}\ecbend{}}
\& \enewcommand\eTLSdel[1]{\ecbdelete{}\etextcolor{del}{\esout{#1}}}
.Ve
.PP
Define editing colors \f(CW\*(C`ins\*(C'\fR and \f(CW\*(C`del\*(C'\fR with existing \f(CW\*(C`xcolor\*(C'\fR color names:
 \ecolorlet{ins}{blue} \ecolorlet{del}{red}
.PP
Or from scratch:
 \edefinecolor{ins}{rgb}{0, 0.5, 0}
.PP
These macros are \s-1NOT\s0 automatically interted at \ebegin{document} like
the original scripts did (see the \fB\s-1ACKNOWLEDGMENTS\s0\fR section below),
because this will not work on files of a multi-file document (those
included by \einclude or \einput).  Furthermore, if you insert the
macros manually, you can tune them as you like, i. e. change text
color or position of changebars. Have a look at the documentation of
the ulem and changebar packages on how to do this!
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-\-nofloats\fR, \fB\-n\fR" 4
.IX Item "--nofloats, -n"
If given, skips contents of figure environments, but does show
insertions and deletions in the caption commands. This is done to
avoid complex messups in subfloat or complex figure environments.
.IP "\fB\-\-debug\fR, \fB\-d\fR" 4
.IX Item "--debug, -d"
Turns on debugging. Temporary files that contain numbered braces are
kept and a raw difference file is written as output file name appended
with '\-wdiff.tex'. In addition, several regular expression diagnostics
are printed. \fBWarning: produces a lot of output.\fR
.SH "AUTHOR"
.IX Header "AUTHOR"
Mark Doll <markdoll<\s-1AT\s0>gmx.net>, Cengiz Gunay <cengique<\s-1AT\s0>users.sf.net>.
.SH "ACKNOWLEDGMENTS"
.IX Header "ACKNOWLEDGMENTS"
.IP "\fB*\fR" 4
.IX Item "*"
Version 0.4, by \s-1CG\s0, 2009/09/15. Added use of GetOpt to take an optional
parameter to skip float (e.g., figure or table) contents. Added an
optional debug mode. Embedded \s-1POD\s0 documentation. Fixed problem
with insertion and deletions appearing in the middle of sectioning
commands by throwing off LaTeX.
.IP "\fB*\fR" 4
.IX Item "*"
Version 0.3, modified by Cengiz Gunay <cengique@users.sf.net>,
2009/06/30. Added some Latex commands that should be excluded and
fixed handling of '\e%' characters.
.IP "\fB*\fR" 4
.IX Item "*"
Version 0.2, is a perl implementation of TeXdiff by Mark Doll
<markdoll@gmx.net>, 2006/08/09. It was derived from the original bash
and perl scripts created by Robert Maron <robmar@mimuw.edu.pl>,
available at http://www.robmar.net/TexDiff/. This version of texdiff
is available at http://mark.doll.name/texdiff/.
