Christian: With > your current patch series, is it possible for Jeremy to configure > interpret-trailers to automatically append a "Made-on-branch: > <current_branch>" trailer whenever he creates a commit? Yes, it's possible. Yesterday, I sent the following patch: [RFC/PATCH 2/2] trailer: add examples to the documentation and it shows a commit-msg hook to do something like that: $ cat >.git/hooks/commit-msg <<EOF #!/bin/sh git interpret-trailers --trim-empty --trailer "git-version: \$(git describe)" "\$1" > "\$1.new" mv "\$1.new" "\$1" EOF $ chmod +x .git/hooks/commit-msg I think you just need to use the following if you want the branch instead of the git version: git interpret-trailers --trim-empty --trailer "git-branch: \$(git name-rev --name-only HEAD)" "\$1" > "\$1.new" It could even be simpler if there was an option (which has already been discussed) that made it possible to modify the file in place. This way one would not need the 'mv "\$1.new" "\$1"' command.
