dispatch

#!/bin/sh
# Shared dispatcher for the global git hooks in this directory.
#
# Because core.hooksPath overrides a repo's own .git/hooks entirely, each
# global hook first chains to the repo-local hook of the same name (so
# per-repo hooks and tools like husky keep working), then triggers the
# fish prompt broadcast.
#
# Usage: dispatch <hook-name> [hook args...]

# Hard recursion guard. Hooks inherit git config (including core.hooksPath)
# through the environment, so a git command run from inside a hook can fire
# these global hooks again. One nested level is where it stops.
