Angelo

A Sinatra-esque DSL for Reel.

Notes/Features

• "easy" websocket support via socket '/path' do |s| route handler
• "easy" websocket stashing via websockets helper
• "easy" event handling via async helpers
• no rack
• optional tilt/erb support
• optional mustermann support

Lots of work left to do!

Quick example

require 'angelo'

class Foo < Angelo::Base

  TEST = {foo: "bar", baz: 123, bat: false}.to_json

  HEART = '<3'
  @@hearting = false

  def pong; 'pong'; end
  def foo; params[:foo]; end

  get '/ping' do
    pong
  end

  post '/foo' do
    foo
  end

  post '/bar' do
    params.to_json
  end

  post '/emit' do
    websockets[:emit_test].each {|ws| ws.write TEST}
    params.to_json
  end

  socket '/ws' do |ws|
    websockets[:emit_test] << ws
    ws.on_message do |msg|
      5.times { ws.write TEST }
      ws.write foo.to_json
    end
  end

  post '/other' do
    websockets[:other].each {|ws| ws.write TEST}
  end

  socket '/other/ws' do |ws|
    websockets[:other] << ws
  end

  socket '/hearts' do |ws|

    # this is a call to Base#async, actually calling 
    # the reactor to start the task
    # 
    async :hearts unless @@hearting

    websockets[:hearts] << ws
  end

  # this is a call to Base.async, defining the task
  # to perform on the reactor
  #
  async :hearts do
    @@hearting = true
    every(10){ websockets[:hearts].each {|ws| ws.write HEART } }
  end

end

Foo.run

Tilt / ERB

To make erb available in route blocks

1. add tilt to your Gemfile: gem 'tilt'
2. require angelo/tilt/erb
3. include Angelo::Tilt::ERB in your app

class Foo < Angelo::Base
  include Angelo::Tilt::ERB

  @@views = 'some/other/path' # defaults to './views'

  get '/' do
    erb :index
  end

end

Mustermann

To make routes blocks match path with Mustermann patterns

1. be using ruby >=2.0.0
2. add 'mustermann' to to your Gemfile: platform(:ruby_20){ gem 'mustermann' }
3. require angelo/mustermann
4. include Angelo::Mustermann in your app

class Foo < Angelo::Base
  include Angelo::Tilt::ERB
  include Angelo::Mustermann

  get '/:foo/things/:bar' do

    # `params` is merged with the Mustermann object#params hash, so
    # a "GET /some/things/are_good?foo=other&bar=are_bad" would have:
    #   params: {
    #     'foo' => 'some',
    #     'bar' => 'are_good'
    #   }

    @foo = params[:foo]
    @bar = params[:bar]
    erb :index
  end

end

NOTE: this always sets the Mustermann object's type to :sinatra
