Most of ticket tracker like Github, pivotal tracker have function to connect your commit to ticket(story).
But every time when you commit copy and paste that of ticket number is annoy...

So I created a script using git hook to add ticket number to your commit automatically.

Script

$ mkdir -p ~/.git-templates/hooks
$ touch ~/.git-templates/hooks/prepare-commit-msg
$ chmod u+x ~/.git-templates/hooks/prepare-commit-msg

Then you can copy & paste this script to prepare-commit-msg

#!/bin/sh

LF=$'\\\x0A'
BRANCH_NAME=$(git symbolic-ref --short HEAD)

if [[ $BRANCH_NAME =~ .*\/[0-9]* ]]; then
  PREFIX=$(echo $BRANCH_NAME | sed -e 's/\(.*\)\/\([0-9]*\)/\1/')
  NUMBER=$(echo $BRANCH_NAME | sed -e 's/\(.*\)\/\([0-9]*\)/\2/')
  if [ $PREFIX = 'story' ]; then
      MESSAGE="[#$NUMBER]"
  else
      MESSAGE="GH-$NUMBER"
  fi
  if [ $NUMBER ]; then
    sed -i.back "1s/^/$LF$LF$MESSAGE$LF/" "$1"
  fi
fi

Configuration

To enable this script run this command.

$ git config core.hooksPath ~/.git-templates/hooks/

Usage

This script expects that your branch is named using this format

Pivotal Tracker

story/1111

Github

issue/1111
fix/1111

When every time you commit script add that number using this format to you commit !!
