SubworkflowLint.main_nf(subworkflow: NFCoreComponent) → tuple[list[str], list[str]]

Lint a main.nf subworkflow file

Can also be used to lint local subworkflow files, in which case failures will be reported as warnings.

The test checks for the following:

• A subworkflow SHOULD import at least two modules
• All included modules or subworkflows are used and their names are used for versions.yml
• The workflow name is all capital letters
• The subworkflow emits a software version

The following checks are performed:

• main_nf_exists: The main.nf file must exist.
• main_nf_script_outputs: The workflow must have an emit: block.
• main_nf_version_emitted: The subworkflow should emit a software version channel. A warning is issued if no versions output is found (can be ignored if the subworkflow uses topic channels).
