Thank you for that!

Johannes already pointed you to the prepare-commit-msg hook, which I
think is the right solution. I wrote a rough sketch for fun (note that
you could write it in whatever language you like if the mix of
perl/shell isn't to your liking):
-- >8 --
#!/bin/sh
# only kick in for vanilla commit, or "-m"
case "$2" in
""|message) ;;
*) exit 0
esac
# common prefix of all changed files
prefix=$(
git diff-index --name-only HEAD |
perl -lne '
if (!defined $prefix) {
$prefix = $_;
} else {
chop $prefix while !/^\Q$prefix\E/;
}
END {
# trim trailing slash if present
$prefix =~ s{/$}{};
print $prefix
}
'
)
# now stick the prefix at the start of the message-in-progress
{
printf '%s' "$prefix: "
cat "$1"
} >"$1".tmp &&
mv "$1".tmp "$1"

[FEATURE] git-commit option to prepend filename to commit message
Hello, I had an idea for a feature for git commit that I wanted to pass along and see if maybe others would also think this would be useful. Very often, I make commits that affect a single file, and have simple commit messages of this form: : The feature would be a command line option for git commit that would automatically prepend the ": " to the commit message. The different cases of its behavior could be: - commit affecting a single file, with commit message given by -m: : prepend ": " to the message given by -m - commit affecting a single file, with commit message from editor: : pre-fill commit message template with ": " - commit affecting multiple files: : use common base directory of all affected files for , behaviors as above for use with -m or editor. Anybody think that this or something like it would be a good convenience? Thank you, John Foerch
