|
== Usage
|
|
|
|
Just launch Guard inside your Ruby / Rails project with:
|
|
|
|
guard
|
|
|
|
or if you use Bundler, to run the Guard executable specific to your bundle:
|
|
|
|
bundle exec guard
|
|
|
|
== Command line options
|
|
|
|
Shell can be cleared after each change with:
|
|
|
|
guard --clear
|
|
guard -c # shortcut
|
|
|
|
The guards to start can be specified by group (see Guardfile DSL below) specifying the `--group` (or `-g`) option:
|
|
|
|
guard --group group_name another_group_name
|
|
guard -g group_name another_group_name # shortcut
|
|
|
|
Options list is available with:
|
|
|
|
guard help [TASK]
|
|
|
|
== Signal handlers
|
|
|
|
Signal handlers are used to interact with Guard:
|
|
|
|
- Ctrl-C - Quit Guard (call each guard's run_all method, in the same order they are declared in the Guarfile)
|
|
- Ctrl-\ - Call each guard's run_all method, in the same order they are declared in the Guarfile
|
|
- Ctrl-Z - Call each guard's reload method, in the same order they are declared in the Guarfile
|
|
|

=== 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!
|
|
|
|
== Guardfile DSL
|
|
|
|
The Guardfile DSL consists of just three simple main methods: `guard`, `watch` & `group`.
|
|
|
|
Required:
|
|
- The `guard` method allows you to add a guard with an optional options hash.
|
|
- The `watch` method allows you to define which files are supervised per this guard. A optional block can be added to overwrite path sent to run_on_change guard method or launch simple command.
|
|
|
|
Optional:
|
|
- The `group` method allows you to group several guards. Groups to run can be specified with the Guard DSL option `--group` (or `-g`). This comes in handy especially when you have a huge Guardfile and want to focus your development.
|
|
|
|
Example:
|
|
|
|
group 'backend' do
|
|
guard 'bundler' do
|
|
watch('Gemfile')
|
|
end
|
|
|
|
guard 'rspec' do
|
|
# Regexp watch patterns are matched with Regexp#match
|
|
watch(%r{^spec/(.+)_spec\.rb})
|
|
watch(%r{^lib/(.+)\.rb}) { |m| "spec/lib/#{m[1]}_spec.rb" }
|
|
watch(%r{^spec/models/.+\.rb}) { ["spec/models", "spec/acceptance"] }
|
|
watch(%r{^spec/.+\.rb}) { `say hello` }
|
|
|
|
# String watch patterns are matched with simple '=='
|
|
watch('spec/spec_helper.rb') { "spec" }
|
|
end
|
|
end
|
|
|
|
group 'frontend' do
|
|
guard 'coffeescript', :output => 'public/javascripts/compiled' do
|
|
watch(%r{app/coffeescripts/.+\.coffee})
|
|
end
|
|
|
|
guard 'livereload' do
|
|
watch(%r{app/.+\.(erb|haml)})
|
|
end
|
|
end
|
|
|
|
== 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
|
|
|
|
def initialize(watchers = [], options = {})
|
|
super
|
|
# init stuff here, thx!
|
|
end
|
|
|
|
# ================
|
|
# = Guard method =
|
|
# ================
|
|
|
|
# If one of those methods raise an exception, the Guard instance
|
|
# will be removed from the active guard.
|
|
|
|
# Call once when guard starts
|
|
# Please override initialize method to init stuff
|
|
def start
|
|
true
|
|
end
|
|
|
|
# Call with Ctrl-C signal (when Guard quit)
|
|
def stop
|
|
true
|
|
end
|
|
|
|
# Call with Ctrl-Z signal
|
|
# This method should be mainly used for "reload" (really!) actions like reloading passenger/spork/bundler/...
|
|
def reload
|
|
true
|
|
end
|
|
|
|
# Call with Ctrl-/ signal
|
|
# This method should be principally used for long action like running all specs/tests/...
|
|
def run_all
|
|
true
|
|
end
|
|
|
|
# Call on file(s) modifications
|
|
def run_on_change(paths)
|
|
true
|
|
end
|
|
|
|
end
|
|
end
|
|
|
