Ruote is a Ruby workflow engine. It’s thus a workflow definition interpreter. If you’re enterprisey, you might say business process definition.
Instances of these definitions are meant to run for a long time, so Ruote is oriented towards persistency / modifiability instead of transience / performance like a regular interpreter is. A Ruote engine may run multiple instances of workflow definitions.
Persistent mostly means that you can stop Ruote and later restart it without losing processes. Modifiability means that you can modify a workflow instance on the fly.
Process definitions are mainly describing how workitems are routed to participants. These participants may represent worklists for users or group of users, pieces of code, …
grab ruote
gem install ruote gem install yajl-ruby
Note : the json gem has a serious bug :
http://github.com/flori/json/issues#issue/21
So yajl-ruby is seriously recommended.
Then
require 'rubygems' require 'ruote' require 'ruote/storage/fs_storage' # preparing the engine engine = Ruote::Engine.new( Ruote::Worker.new( Ruote::FsStorage.new('ruote_work'))) # registering participants engine.register_participant :alpha do |workitem| workitem.fields['message'] = { 'text' => 'hello !', 'author' => 'Alice' } end engine.register_participant :bravo do |workitem| puts "I received a message from #{workitem.fields['message']['author']}" end # defining a process pdef = Ruote.process_definition :name => 'test' do sequence do participant :alpha participant :bravo end end # launching, creating a process instance wfid = engine.launch(pdef) engine.wait_for(wfid) # blocks current thread until our process instance terminates # => 'I received a message from Alice'
