Easy integration with GIT and Latexdiff

git-latexdiff.sh

#!/bin/bash
TMPDIR=$(mktemp -d /tmp/git-latexdiff.XXXXXX)
ORIDIR=`pwd`

TEX=$1
VER=$2
if [ -z "$2" ];then
        VER='HEAD'
fi

if [ -z "$1" ];then
        TEX=`grep  'begin{document}' *.tex | grep -m 1 begin | cut -d\: -f1`
fi

git clone . "$TMPDIR/"
cd "$TMPDIR"
git checkout $VER
latexdiff --config="PICTUREENV=(?:picture|algorithm|eqnarray|comment|tikzpicture|DIFnomarkup)[\w\d*@]*" --flatten "$TEX" "$ORIDIR/$TEX" > diff.tex
latex  -interaction=nonstopmode diff.tex &> /dev/null
bibtex  diff.aux
latex  -interaction=nonstopmode diff.tex &> /dev/null
pdflatex -interaction=nonstopmode diff.tex &> /dev/null
evince diff.pdf
rm -rf $TMPDIR
echo 
echo "$0 $TEX $VER"
echo

Thanks for this, it was very useful. I ran into a problem with the variable name TMPDIR, since that name is used by Ghostscript (which in my TeX files is called by epstopdf). Ghostscript was throwing an error about being unable to write a temporary file during the EPS to PDF conversion process. It took me awhile to figure out what the problem was, so I thought it might be worth sharing that info.
