Git hook for redmine tickets

I use git and like to have a ticket for every bit of work I do on my projects. I also have a preferred way to prefix commit messages, something like:

123 - Fix this broken thing
 
Description of commits here

Where Fix the broken thing is the ticket subject in RedMine.

It’s not sophisticated or complex but it shows a nice one-liner in GitHub which I like.

To make sure I always stay consistent I have a simple git hook to tweak the commit message:

#!/usr/bin/env ruby
 
require 'rubygems'
require 'httparty'
 
REDMINEURL="http://your.redmine"
 
msg = File.read(ARGV[0])
 
# If the msg starts with number we've been here already
# and no doubt someone is amending existing log entries
exit if msg =~/^\d/
 
begin
    if msg =~ /On branch (\d+)(.+?)\n/
        branch = $1
        ticketurl = "#{REDMINEURL}/issues/#{branch}.json"
        puts "Fetching #{ticketurl}"
        headers = {"User-Agent" => "meh"}
 
        ticket = HTTParty.get(ticketurl, {:headers => headers})
 
        msg = "%d - %s\n\n%s" % [ branch, ticket["issue"]["subject"], msg ]
 
        File.open(ARGV[0], "w") {|f| f.print msg}
    end
rescue Exception => e
    puts "git hook failed: #{e.class}: #{e}"
    sleep 2
    exit
end

It requires that I name my branches something like <ticket number>_anything_else which might be too limited but works for me.

This will prepare my commit message with the ticket subject before I commit. I don’t do much off-line coding so generally don’t have to worry about connectivity checks.
