git-latexdiff is a tool to graphically visualize differences between
different versions of a LaTeX file. Technically, it is a wrapper
around git and
latexdiff.
If your LaTeX source is split accross several *.tex files,
git-latexdiff can call
latexpand to expand it before
running latexdiff (this usually works better than using latexdiff --flatten).
To get the manpage (needed to get git-latexdiff --help to work), you
need the a2x tool from the asciidoc package.
To install git-latexdiff in Git's exec-path and generate and install
a manpage, run this command from the root directory of
git-latexdiff's distribution:
make install
If Git was installed as root, you will need to run this command as root, for example using:
sudo make install
If it fails, you may try installing only the script (you can still
read the documentation using git latexdiff -h):
make install-bin
Once the script git-latexdiff and the manpage git-latexdiff.1 are
installed, you're ready to go (no configuration file to edit).
A simple way to install git-latexdiff is to copy the file
git-latexdiff anywhere in your $PATH (e.g. in /usr/local/bin,
run echo $PATH get the list) or in Git's exec-path (run git --exec-path to get it).
To get the documentation, you need to generate it:
make git-latexdiff.1
and then copy git-latexdiff.1 in your man-path (run git --man-path
to get the location).
