Project description
ewokscore
ewokscore provides an API to define workflows and implement tasks in ewoks.
Install
pip install ewokscore[test]
Test
pytest --pyargs ewokscore.tests
Getting started

):
def run(self):
result = self.inputs.a

result += self.inputs.b
self.outputs.result = result
# Define a workflow with default inputs

# Define task inputs
inputs = [{"id": "task1", "name": "a", "value": 10}]
# Execute a workflow (use a proper Ewoks task scheduler in production)
varinfo = {"root_uri": "/tmp/myresults"} # optionally save all task outputs
result = execute_graph(workflow, varinfo=varinfo, inputs=inputs)
print(result)
