I wrote a little shell-script that allows one to use latexdiff on files versionned by Git, with e.g. git latexdiff HEAD^ --main foo.tex --output foo.pdf Essentially, it does a checkout of the old and new revisions, and calls latexdiff + pdflatex for you. The result is attached in case anyone is interested. It may be relevant to add this to contrib/ in git.git. If anyone's interested, let me know, and I'll resend the code in the form of a patch doing that.

I could not test it in detail until now, but i had two or three runs with an article draft and it seems to work. Long story short, i would appreciate it if your tool would be integrated in git. T.

But I did wonder what your rationale was in making a separate command as opposed to providing a script that could be plugged in as an external diff. -Peff ``` ## Matthieu Moy, 2012-02-14 23:13 Subject: Re: git-latexdiff: Git and Latexdiff working together Message-ID: URL: https://gitlist.dev/e/vpq4nut6maj.fsf%40bauges.imag.fr In-Reply-To: <20120214211629.GA23649@sigill.intra.peff.net> ``` Jeff King writes: > My latex usage is all from a past life, so I didn't even try out your > tool.

My LaTeX documents are usually sets of .tex files including each other, plus figures and possibly Makefiles. So, git-latexdiff does a full checkout of the old and new tree, then runs latexdiff on the main file, and then compiles the result. A diff driver would work well for a standalone file, but I don't think you can plug it in this kind of situation. Also, git-latexdiff has a few hacks like detecting the main latex file automatically by grepping all .tex files for "documentclass", detecting the presence of a Makefile to compile the document, ... that would hardly fit in a diff driver. That said, that may be just me not knowing diff drivers or difftools well enough. -- Matthieu Moy http://www-verimag.imag.fr/~moy/ ``` ## Jeff King, 2012-02-14 23:31 Subject: Re: git-latexdiff: Git and Latexdiff working together Message-ID: <20120214233151.GA25651@sigill.intra.peff.net> URL: https://gitlist.dev/e/20120214233151.GA25651%40sigill.intra.peff.net In-Reply-To: ``` On Wed, Feb 15, 2012 at 12:13:40AM +0100, Matthieu Moy wrote: > Jeff King writes: > > > My latex usage is all from a past life, so I didn't even try out your > > tool.

I didn't think about the fact that there's a whole ecosystem of files that go into producing the output. > That said, that may be just me not knowing diff drivers or difftools > well enough. No, your analysis is right. A diff driver wouldn't work well at all. Thanks for satisfying my curiosity. -Peff ```
