ngannotate-rails

Use https://github.com/olov/ng-annotate in the Rails asset pipeline.

Installation

Add this line to your application's Gemfile:

gem 'ngannotate-rails'

And then execute:

$ bundle

That's it! ngannotate-rails integrates seamlessly into the Rails asset pipeline; your JavaScript or CoffeeScript assets will automatically be run through the ng-annotate pre-minifier.

Usage

By default ng-annotate processing is disabled in development and test environments. Processing, however, can be enforced by specifying NG_FORCE=true option.

Options available as environment variables:

NG_REGEXP     - regexp passed to ng-annoate
                see ng-annotate documentation
NG_OPT        - comma separate list of "opt=value" key pairs passed as options to ng-annotate
                see ng-annotate documentation
NG_FORCE=true - force ng-annoate processing in development/test environment

Examples,

# Test assets compile in rails development environment
# (assuming config/environments/development.rb is adjusted approriately)
NG_FORCE=true RAILS_ENV=development bundle exec rake assets:clean assets:precompile

Testing assets locally

To allow testing precompiled assets locally in development environment.

config/environments/development.yml

#
# to allow testing assets:precompile in development environment
# Usage:
#   time NG_FORCE=true RAILS_ENV=development bundle exec rake assets:clean assets:precompile:primary
#   NG_FORCE=true rails s -p 3001
#
if ENV['NG_FORCE'] == 'true'
  config.assets.compress = true
  config.assets.compile = false
  config.assets.digest = true
  config.assets.debug = false
end

precompile & start server

time NG_FORCE=true RAILS_ENV=development bundle exec rake assets:clean assets:precompile:primary
NG_FORCE=true rails s -p 3001

Versioning

The ngannotate-rails version number mirrors the version number for the version of ng-annotate that is bundled with it. For minor patch releases, when ng-annotate version is not changing, 4th digit is used (For example, "0.9.6.1"). Every released version is tagged with tag "v[VERSION]".

Help

Q: I installed ngannotate-rails, but my assets aren't getting processed with ng-annotate.

A: Remember to delete tmp/cache/assets or touch all the related asset files so that the cached versions get regenerated. If you've precompiled your assets into public/assets, you'll need to re-precompile them.

Hacking

Upgrading ng-annotate

The actual ngannotate project is bundled into this gem via Browserify. You can update to the latest version of ng-annotate via Rake:

rake ngannotate:build

Test Application

There is a Rails 3 application bundled in example/ that you can use to test the asset pipeline integration. Don't forget to remove tmp/cache/assets after upgrading to the latest version of ng-annotate.
