Can a Git hook automatically add files to the commit?

Question

I\'d like to add an automatically generated file to the same commit using a pre- or post-commit hook in Git, dependent on the files that were modified in that commit. How w

I had the same need and this approach worked pretty well for me:

#!/bin/sh
files='git diff --cached --name-only'
re=""
if [[ $files =~ $re ]]
then
   echo "Creating files"
   create_my_files && git add my_files
fi

where "create_my_files" should be executable, for example if it is a python file you could execute it as "python create_my_files && git add my_files"

and is true you don't need a pre-commit to commit again (that would create a infinite nasty loop :p)
