Multiplexer

One self-contained script. Copy src/multiplexer into .git/hooks — no pip install, no package. It runs every executable under hooks/<hook-type>/ at the root of a Git repository.

The same file can be installed as pre-commit, commit-msg, pre-push, pre-merge-commit, or any other supported hook. The hook type is the name Git invoked, not the name of the source file.

What it does

• Discovers executable subhooks in hooks/<type>/ and runs them in name order
• Forwards Git's command-line arguments to each subhook
• Replays Git's stdin so every subhook sees the same payload
• Inherits the terminal so optional prompts appear; other hooks just run
• Stops on the first non-zero exit code

Next steps

• Getting started — copy the script into .git/hooks
• Usage — layout, prompts, and fail-fast behaviour
• Reference — hook names, arguments, and stdin
• Examples — copy-paste install and subhook recipes
