Jekyll Forman Guard Bundler

Introduction

This post is a quick “How did I setup my Jekyll environnement ?”. We are going all the tools that are quite awesome in Ruby.

Goal

The goal is simple :

  1. I want to be able to install any dependent Gem with a on-liner command
  2. I want to be able to run a Jekyll server that auto updates.

We are going to play with : Bundler, Guard and foreman.

Bundler

Bundler let us run bundle install to get all Ruby Gems we will need ; It use a file name Gemfile. The gems we need are simple : jekyll, guard and some Guard extensions.

source "http://rubygems.org"

gem 'jekyll'
gem 'guard'
gem 'guard-jekyll2'
gem 'guard-shell'
gem 'guard-bundler'

Guard

Guard is a command line tool to easily handle events on file system modifications.

Guard will be watching file we told him and run action in consequence ; The file is name Guardfile.

guard 'jekyll2' do
  watch %r{.*}
end

guard :bundler do
  watch('Gemfile')
end
# vim:filetype=ruby

Foreman

Finally, foreman will let us declare our processes and will handle the start, forward the output and handle the shutdown. It can then export its configuration into more production-ready file (init, upstard, …) ; It uses a file named Procfile.

We will tell foreman to run :

  • The jekyll build-in server : jekyll --server
  • Guard, to handle file changes in background.
web: bundle exec jekyll --server
guard: bundle exec guard

And that’s all folk. Now, you just need to run foreman in the Jekyll-powered directory and edit your files.
