CWL 2 Inputs

cwl2inputs is a Transpiler-Mate plugin that generates an inputs.yaml template for a selected CWL workflow or tool using cwltool's Python APIs.

Install from source

Use Python 3.10 or newer. From this repository:

python -m pip install . transpiler-mate-runtime

The plugin registers in transpiler_mate.plugins and is invoked through the runtime; there is no standalone cwl2inputs executable.

Usage

transpiler-mate cwl2inputs --output inputs.yaml 'workflow.cwl#main'

For the burned-area workflow, from the organization workspace:

transpiler-mate cwl2inputs \
  --output tmp/build/burned-area-severity/inputs.yaml \
  'tmp/burned-area-severity.cwl#burned-area-severity'

--output defaults to inputs.yaml. Parent directories are created as needed; an existing output file is replaced after successful template generation. Always select the process with #<process-id>, including single-process documents. The runtime requires document-level Schema.org SoftwareApplication metadata.

The plugin uses the already-resolved CWL graph and calls cwltool's load_tool and make_template APIs. It does not execute workflows or containers. Defaults, example values, and YAML comments come from cwltool. Input ordering may differ from running cwltool on the original source because the runtime normalizes the document.

Templates are starting points: replace file/directory paths and other placeholders before execution. Named optional schemas may appear as schema URI placeholders; replace them with a value matching the schema or null.
