post-checkout

#!/bin/bash
#
# A hook script to call trk with the new branch name.
# This hook is invoked when a git checkout is run after having updated the worktree. The hook is given three parameters:
# the ref of the previous HEAD
# the ref of the new HEAD (which may or may not have changed)
# a flag indicating whether the checkout was a  branch checkout (changing branches, flag=1) or a file checkout (retrieving a file from the index, flag=0).

# This hook cannot affect the outcome of git checkout.

# To track branches with trk, it is recommended to do either of the following:
# * Copy this file to ./.git/hooks/post-checkout
# * Append the below lines to ./.git/hooks/post-checkout

# The Makefile can also be used to copy the hooks to the .git/hooks directory
# $> make sync-hook

if [ "$3" = 1 ]; then
    # Checked out a branch - what branch are we on now?
    # (Skip the rest if we're on a detached HEAD.)
    curbranch=$(git symbolic-ref --short HEAD 2>/dev/null) || exit 1
    # echo "switching to as-yet-unvisited-branch $curbranch"
    trk branch $curbranch
