Complex CWL types¶

Follow below an example to demonstrate how the library handles and convert a CWL where inputs are declared with hybrid types.

1. Parsing¶

In this sample we'll show the access from a remote public URL.

from cwl_loader import load_cwl_from_location
from cwl2ogc import BaseCWLtypes2OGCConverter

cwl_document = load_cwl_from_location(
    "https://raw.githubusercontent.com/transpiler-mate/cwl2ogc/refs/heads/develop/tests/artifacts/cwl-types/complex-cwl-types.cwl"
)
cwl_converter = BaseCWLtypes2OGCConverter(cwl_document)
from cwl_loader import load_cwl_from_location
from cwl2ogc import BaseCWLtypes2OGCConverter

cwl_document = load_cwl_from_location(
    "https://raw.githubusercontent.com/transpiler-mate/cwl2ogc/refs/heads/develop/tests/artifacts/cwl-types/complex-cwl-types.cwl"
)
cwl_converter = BaseCWLtypes2OGCConverter(cwl_document)

      1 from cwl_loader import load_cwl_from_location

      4 cwl_document = load_cwl_from_location(
      5     "https://raw.githubusercontent.com/transpiler-mate/cwl2ogc/refs/heads/develop/tests/artifacts/cwl-types/complex-cwl-types.cwl"

ModuleNotFoundError: No module named 'cwl2ogc'

3. Inputs conversion¶

Once the document is parsed, invoke the cwl2ogc APIs to convert the CWL inputs to the OGC JSON format:

import sys

cwl_converter.dump_inputs(stream=sys.stdout, pretty_print=True)
import sys

cwl_converter.dump_inputs(stream=sys.stdout, pretty_print=True)

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

      1 import sys
      2 
----> 3 cwl_converter.dump_inputs(stream=sys.stdout, pretty_print=True)

NameError: name 'cwl_converter' is not defined

2. Outputs conversion¶

Users can reuse the BaseCWLtypes2OGCConverter instance to convert the CWL outputs to the OGC JSON format:
