SUPERSEDED BY spectator-emacs

ESpectator (a fork of Spectator that integrates with emacs)

ESpectator provides discreet notifications in the emacs modeline, via the Enotify emacs notification system.

Test results are displayed in an emacs buffer, so no more switching between emacs and the window were the test results are displayed are necessary :-)

If you hate growl-style popups and prefer a simple indicator on the modeline, ESpectator is for you. It's best used together with RSpec Org Formatter, which provides org formatted test results that do look nice on emacs.


Emacs side

You need to install Enotify first. Please refer to its README for this step.

Copy the emacs/enotify-espectator.el file in a directory in your load-path and add this line after the enotify configuration in your .emacs:

    (require 'enotify-espectator)

Note that enotify uses the TCP port 5000 to listen to notification messages. If you specified a different port, refer to the ``Advanced'' section of this document to see how to specify various ESpectator options


In your specs.watchr file just add:

    require 'rspec-rails-watchr-emacs'
    @specs_watchr ||=

Then launch watchr as usual (probably bundle exec watchr). If you are using RspecOrgFormatter, see the Advanced section of this document.


The normal behavior is similar to autotest --fast-start --no-full-after-failed but gives the user a bit more control over execution. By hitting CTRL+C (or CMD+. on OSX) you get the following prompt:

^C (Interrupted with CTRL+C)
--- What to do now? (q=quit, a=all-specs, r=reload): 


ESpectator supports the following options (here reported with their default values):

    { :enotify_port => 5000, # TCP port for the enotify connection
      :enotify_host => 'localhost', # host name for the enotify connection
      :notification_message => { # Text displayed on the modeline when
        :failure => "F",         # there is at least 1 failing spec
        :success => "S",         # there are no failing or pending spec
        :pending => "P"          # there are no failing spec and at least 1 pending
      :notification_face => { # Face used to display the text in the modeline
        :failure => keyword(:failure),
        :success => keyword(:success),
        :pending => keyword(:warning)},
      # custom_extract_summary_proc: takes the result text as argument
      # and returns an hash of the form
      # {:errors => #errors
      #  :pending => #pending
      #  :examples => #examples
      #  :status => (:success|:failure|:pending) }
      :custom_extract_summary_proc => nil, 
      # index of the Rspec summary line.
      # It should look like this:
      # 25 examples, 2 failures, 1 pending
      :error_count_line => -1,
      # A proc that takes two arguments |path, specs|
      # where path is the file that has been modified
      # and specs is a vector containing all the spec
      # files.
      # It should return a vector containing the matching
      # specs for `path'.
      :custom_matcher => nil

An example of a custom matcher:

    @specs_watchr ||=,
       :custom_matcher => lambda { |path, specs|
               case path
               when %r{lib/calibration_with_coefficients}
               when %r{app/models/telemetry_parameter}

To use it with the RSpec Org Formatter, the :error_count_line option should be set to -6:

    @specs_watchr ||=, :error_count_line => -6)
