This sample demonstrates having a workflow interpret/invoke arbitrary steps defined in a DSL. It is similar to the DSL samples in TypeScript, in Go, and in Python.
To run, first see README.md for prerequisites. Then, in another terminal, start the Ruby worker from this directory:
bundle exec ruby worker.rb
Now, in another terminal, run the following from this directory to execute a workflow of steps defined in workflow1.yaml:
bundle exec ruby starter.rb workflow1.yaml
This will run the workflow and show the final variables that the workflow returns. Looking in the worker terminal, each step executed will be visible.
Similarly we can do the same for the more advanced workflow2.yaml file:
bundle exec ruby starter.rb workflow2.yaml
This sample gives a guide of how one can write a workflow to interpret arbitrary steps from a user-provided DSL. Many DSL models are more advanced and are more specific to conform to business logic needs.
