    texdiff - Compares two (La)TeX documents to create a merged version
    showing changes, similar to that of 'Change Tracking' in some word

    texdiff [--nofloats|-n] old.tex new.tex [diff.tex]

    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 "changebar"
    package (although only after running "dvips", in "xdvi" the bars are one
    inch too far left to compensate the one inch offset inserted by TeX
    printer drivers).

    "texdiff" uses and therefore requires the "wdiff" 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 "wdiff" tearing apart pairs of braces. Therefore
    "texdiff" is a perl script that calls "wdiff" internally and fixes
    "wdiff"'s output by re-pairing braces again and handling some commonly
    used LaTeX macros.

    For texdiff to work, the following LaTeX code must be inserted in the
    preamble of the LaTeX document:

     \usepackage{xcolor} \usepackage{ulem} \usepackage{changebar}

    Define editing colors "ins" and "del" with existing "xcolor" color
    names: \colorlet{ins}{blue} \colorlet{del}{red}

    Or from scratch: \definecolor{ins}{rgb}{0, 0.5, 0}

    These macros are NOT automatically interted at \begin{document} like the
    original scripts did (see the ACKNOWLEDGMENTS section below), because
    this will not work on files of a multi-file document (those included by
    \include or \input). 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!

    --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.

    --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. Warning: produces a lot of output.

    *   Version 0.4, by CG, 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 POD documentation. Fixed
        problem with insertion and deletions appearing in the middle of
        sectioning commands by throwing off LaTeX.

    *   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 '\%' characters.

    *   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/.

texd­iff – Com­pare doc­u­ments and pro­duce tagged merge

Two files are com­pared and a new file is out­put. When the out­put file is pro­cessed with 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 change­bar pack­age.
