galaxy.tool_util.cwl.parser module

This module provides proxy objects around objects from the common workflow language reference implementation library cwltool. These proxies adapt cwltool to Galaxy features and abstract the library away from the rest of the framework.

Adapt a CWL job object to the Galaxy API.

CWL derived tools in Galaxy can consume a job description sort of like CWL job objects via the API but paths need to be replaced with datasets and records and arrays with collection references. This function will stage files and modify the job description to adapt to these changes for Galaxy.
