Document ext.args in meta yml

[awgymer]

This closes #3444

An analogous PR to nf-core/modules will need to be made to update the module meta yml schema json if this is approved.

This PR adds:

• ext.args info from meta.yml displayed by modules info
• Lint check which warns if any expected ext.args* are not documented in meta.yml

Will need to add a test for this lint check/info output but not sure how best to achieve this before an update to nf-core/modules?

Hi @awgymer,

It looks like this pull-request is has been made against the awgymer/nf-core-tools main branch.
The main branch on nf-core repositories should always contain code from the latest release.
Because of this, PRs to main are only allowed if they come from the awgymer/nf-core-tools dev branch.

You do not need to close this PR, you can change the target branch to dev by clicking the "Edit" button at the top of this page.
Note that even after this, the test will continue to show as failing until you push a new commit.

Thanks again for your contribution!

Looking good!
We could automatically add all the args to the meta.yml when running nf-core modules lint --fix, this is done by update_meta_yml_file() function in nf_core/modules/lint/__init__.py. Then we can gradually keep adding the change to modules, so we don't have to do a big bulk update PR, especially since this will be a warning, not an error.
I am also working on some modifications to the meta.yml here, these shouldn't affect your changes, but it would be good if we can avoid big merge conflicts.
