Workflow Exectution Engine Library

All code in this package is provided under the LGPL-3 license. Please read the file COPYING.

Tested for MRI 2.6, 2.7

Example Process (DSL)

class SimpleWorkflow < WEEL
  handlerwrapper SimpleHandlerWrapper

  endpoint :ep1 => "orf.at"
  data :a => 17

  control flow do
    call :a1, :ep1, parameters: { :a => data.a, :b => 2 } do
      data.a += 3
    end
  end
end

HandlerWrappers are classes that implement communication protocols. Endpoints hold the communication targets and can be reused throughout the control flow. Data elements are control flow scoped variables.

Please check out the "example" directory to see a minimal set of necessary artefacts.
