Guard::Rake

Guard::Rake allows you to automatically run a Rake task when files are modified.

Install

Please be sure to have Guard installed before continuing.

Install the gem:

$ gem install guard-rake

Add it to your Gemfile

gem 'guard-rake'

Add the default Guard::Rake template to your Guardfile by running this command:

$ guard init rake

Usage

Please read the Guard usage documentation.

Guardfile

Guard::Rake comes with a default template that looks like this:

guard 'rake', :task => 'doit' do
  watch(%r{^some_files/.+$})
end

This will run the rake task doit from your Rakefile whenever any of the watched files change.

List of available options:

:task => 'doit'              # name of the task to be executed, required
:run_on_all => false         # runs when the 'run_all' signal is received from Guard (enter is pressed), default: true
:run_on_start => true        # runs when guard is started, default: true
:task_args => []             # arguments to pass to Rake::Task#invoke, default: []

Rake task arguments

By default, the changed file paths will be passed into the rake task. Example:

task :doit, :paths do |t, args|
  args.paths  # Will contain an array of changed paths
end

You may also use this in conjunction with the :task_args options. Anything in :task_args will be passed in first, then the array of changed paths. Example:

# Guardfile
guard 'rake', :task => 'doit', :task_args => ['a', 'b'] do
  watch(%r{^some_files/.+$})
end

# Rakefile
task :doit, [:first, :second, :paths] do |t, args|
  args.first  # "a"
  args.second # "b"
  args.paths  # ['changed1.rb', 'changed2.rb']
end
