We perform this in +# the post-commit phase so that we can be sure we properly detect all +# the files in the diff (this is difficult during the commit-msg hook, +# since there's no cross-platform way to detect when a commit is being +# amended). + +# However, since this is a post-commit hook, it's too late to error +# out and abort the commit: it's already done! As a result, this hook +# is purely advisory, and instead we error out when trying to push +# (see "pre-push" in this directory). + +### Code: + +# Prefer gawk if available, as it handles NUL bytes properly. +if type gawk >/dev/null 2>&1; then + awk="gawk" +else + awk="awk" +fi + +git rev-parse HEAD | $awk -v reason=post-commit \ + -f .git/hooks/commit-msg-files.awk |
