Guard support for jasmine-headless-webkit

Add running your Jasmine specs to your Guardfile via jasmine-headless-webkit. Nice!

guard 'jasmine-headless-webkit' do
  watch(%r{^app/assets/javascripts/(.*)\..*}) { |m| newest_js_file("spec/javascripts/#{m[1]}_spec") }
end

gem install guard-jasmine-headless-webkit and then guard init jasmine-headless-webkit in your project directory to get started. You should also put it in your Gemfile because, hey, why not, right?

Output is colored by default. If you want it not colored, place a --no-colors option into the project's or your home folder's .jasmine-headless-webkit file.

guard options

• :all_on_start => false to not run everything when starting, just like guard-rspec.
• :run_before => "<command to run> to run a command before running specs. If the command fails, the test run stops.
• :jammit => true to run jammit -f 2>/dev/null before the tests for the current file change are run.
• :valid_extensions => %w{ to run jammit -f 2>/dev/null before the tests for the current file change are run.

What's the deal with newest_js_file?

Since one could, theoretically, have a CoffeeScript app file and a JavaScript spec file (or vice versa), the search for the correct matching file is a little more complicated. newest_js_file extends the Guard DSL to search the given path for the newest .js or .coffee file:

newest_js_file('spec/javascripts/models/my_model')
  #=> search for Dir['spec/javascripts/models/my_model*.{js,coffee}'] and return the newest file found

If you 100% know you won't need that support, modify your Guardfile as appropriate.

...and the .jst file search?

I use Backbone.js a lot, and I put my Underscore view templates in app/views/*.jst and mash them all together with Jammit for use in my apps. Feel free to change that, it's your Guardfile after all. Or, try it. It's easy to do in your assets.yml file:

templates:
- app/views/*.jst
