Please be sure to have Guard installed before continuing.

For info about Guard and it's plugins, see Guard usage doc

Guardfile

You can adapt your 'view' files like you want. Please read Guard doc for more info about Guardfile DSL.

guard 'livereload' do
  watch(%r{app/views/.+\.(erb|haml|slim)})
  watch(%r{app/helpers/.+\.rb})
  watch(%r{public/.+\.(css|js|html)})
  watch(%r{config/locales/.+\.yml})
  # Rails Assets Pipeline
  watch(%r{(app|vendor)(/assets/\w+/(.+\.(css|js|html))).*}) { |m| "/assets/#{m[3]}" }
end

Options

LiveReload guard has 6 options that you can set like this:

guard 'livereload', grace_period: 0.5, override_url: true do
  # ...
end

Available options:

notify: true          # default false
host: '127.3.3.1'     # default '0.0.0.0'
port: '12345'         # default '35729'
apply_css_live: false # default true
override_url: false   # default false
grace_period: 0.5     # default 0 (seconds)
js_template: './my_livereload.js.erb' # default is livereload.js.erb from gem

Additional custom JS template options (see livereload.js.erb for details):

js_apple_webkit_extra_wait_time: 50 # default is 5 (see issue #123)
js_default_extra_wait_time: 100 # default is 200

notify uses Guard's system notifications. See LiveReload configuration doc from version 1.x for more info about other options.

Troubleshooting

To work out what's wrong and where, just follow this easy guide: https://github.com/guard/guard-livereload/wiki/Troubleshooting

Other issues:

1. "hw.ncpu" is an unknown key.

Solution: just upgrade the listen gem to '3.x' (Listen is used by Guard).
