A quick follow-up to a post from a few months ago on how our team has a naming convention for git branches when we’re working on Lighthouse tickets (read previous post).

I’ve just put together a quick git hook for commit-msg, which will automatically amend the commit message with the current ticket number when you’re following the branch naming conventions described here.

Just toss this gist into .git/hooks/commit-msg.

  #!/bin/sh

  #
  # Will append the current Lighthouse ticket number to the commit message automatically
  # when you use the LH_* branch naming convention.
  #
  # Drop into .git/hooks/commit-msg
  # chmod +x .git/hooks/commit-msg

  exec < /dev/tty

  commit_message=$1
  ref=$(git symbolic-ref HEAD 2> /dev/null) || return
  branch=${ref#refs/heads/}

  if [[ $branch =~ LH_(.*) ]]
  then
  lighthouse_ticket=${BASH_REMATCH[1]}

    echo "What is the state of ticket #${lighthouse_ticket}? " 
    echo "(o)pen " 
    echo "(h)old" 
    echo "(r)esolved" 
    echo "Enter the current state for #${lighthouse_ticket}: (o)" 

    state="open" 

    read state_selection

    case $state_selection in
      "o" )
        state="open" 
        ;;
      "h" )
        state="hold" 
        ;;
      "r" )
        state="resolved" 
        ;;
    esac
  echo >&2 "[#${lighthouse_ticket} state:${state}]" >> "$1" 
    exit 0
  fi

Then a quick example of how this works…

  ➜  bin git:(LH_9912 ♻ ) git ci -m "another test" 
  What is the state of this ticket? 
  (o)pen 
  (h)old
  (r)esolved
  Enter the current state: (o)
  h

Now to see this in action… (screenshot)

Then we’ll check out the git log really quick.

➜  bin git:(LH_9912) git log

    another test
    [#9912 state:hold]

Thanks to Andy for helping me figure out how to read user input during a git hook.
