- Tested on Ruby 1.8.6, 1.8.7 & 1.9.2
== Install
Install the gem:
gem install guard
Add it to your Gemfile (inside test group):
gem 'guard'
Generate an empty Guardfile with:
guard init
Add guard(s) you need (see available guards below)
=== On Mac OS X
Install rb-fsevent for {FSEvent}[http://en.wikipedia.org/wiki/FSEvents] support
gem install rb-fsevent
Install growl for Growl notification support
gem install growl
=== On Linux
Install rb-inotify for {inotify}[http://en.wikipedia.org/wiki/Inotify] support
gem install rb-inotify
Install libnotify for libonity notification support
gem install libnotify
== Usage
Just launch Guard inside your ruby/rails project with:
guard
Shell can be cleared after each change with:
guard -c
Options list is available with:
guard help [TASK]
Signal handlers are used to interact with Guard:
- Ctrl-C - Quit Guard (call stop guard(s) method before)
- Ctrl-\ - Call run_all guard(s) method
- Ctrl-Z - Call reload guard(s) method

=== Add a guard to your Guardfile
Add it to your Gemfile (inside test group):
gem '<guard-name>'
Add guard definition to your Guardfile by running this command:
guard init <guard-name>
You are good to go!
== Create a guard
Create a new guard is very easy, just create a new gem with this basic structure:
lib/
guard/
guard-name/
templates/
Guardfile (needed for guard init <guard-name>)
guard-name.rb
lib/guard/guard-name.rb inherit from guard/guard and should overwrite at least one of the five guard methods. Example:
require 'guard'
require 'guard/guard'
module Guard
class GuardName < Guard
# ================
# = Guard method =
# ================
# Call once when guard starts
def start
true
end
# Call with Ctrl-C signal (when Guard quit)
def stop
true
end
# Call with Ctrl-Z signal
def reload
true
end
# Call with Ctrl-/ signal
def run_all
true
end
# Call on file(s) modifications
def run_on_change(paths)
true
end
end
end
Looks at available guards code for more concrete example.
== Guardfile DSL
Guardfile DSL consists of just two simple methods: guard & watch. Example:
guard 'rspec', :version => 2 do
watch('^spec/(.*)_spec.rb')
watch('^lib/(.*)\.rb') { |m| "spec/lib/#{m[1]}_spec.rb" }
watch('^spec/spec_helper.rb') { "spec" }
watch('^spec/spec_helper.rb') { `say hello` }
end
- "guard" method allow to add a guard with an optional options hash
- "watch" method allow to define which files are supervised per this guard. A optional block can be added to overwrite path sending to run_on_change guard method or launch simple command.
== TODO
- Add more specs, help are welcome because I'm not sure about how to test stuff like this :-)
