Feature/add continue statement to grammar

Related Issues:

• Support CONTINUE Statement #47

This should add support of the CONTINUE statement.

Notes: Seems that the tests are failing, but they appear to have been failing prior to changes, as well. Open to thoughts, there!

Thanks, @engineerjoe440!

Let me take a look into those test failures. (Actually I'll have to get back to you next week, sorry 'bout that...)

[engineerjoe440]

Don't be sorry! That's how this stuff goes sometime. Let me know if there's anything you find that I can change to help get fixes in place all in one shot. :)

[klauer]

@engineerjoe440 much appreciated 👍

I did some CI fixes in #49 - Python 3.8 failing is a bit of a mystery, but we're going to ignore it for now.
Would you mind rebasing this PR?

[engineerjoe440]

Absolutely! Will do! Thanks @klauer

Well, I can see the same failures when I don't have apischema installed. I do see everything load properly when I run the tests locally (with apischema installed, mind you). So, I wonder if it might be beneficial to have that module installed in the 3.8 test? Maybe that could be broken out as a separate test for its uniqueness?

Thoughts?

Thanks again, @klauer 🎉 !!!!

[klauer]

Well, I can see the same failures when I don't have apischema installed.

Hmm, can you paste the failure output? What I see in CI is it failing on import of apischema - which is installed there, by the way, as a dev dependency in requirements-dev.txt

Edit: also, I'm going to push one additional test and then merge this. It looks good to me. PLC programmers may balk at the idea of "CONTINUE" outside of a loop, but I think that check could/should happen at a higher level and not fail during parsing outright, I think.

[engineerjoe440]

Sorry, I might have made that even more confusing. I was seeing the apischema errors when I didn't have that package installed. Notably, I'm running on Python 3.11, so it's a bit odd.

Thank you, @klauer!!! This is very exciting, and will free up some of my work on a linter! ❤️ 🎉

[klauer]

Your continued contributions are very much appreciated! Glad it has been of use to you. 👍

Ah, I see - the errors are a bit different from what you pasted.

The test suite requires apischema to be run completely, so those errors you pasted above are legitimate. The docs are very likely lacking, but requirements-dev.txt is considered a necessity for running the full test suite.

The weird/unexpected failure is the Python 3.8 job which shows:

blark/__init__.py:4: in <module>
    from .parse import get_parser, parse_project, parse_source_code
blark/parse.py:17: in <module>
    from . import summary

    from . import transform as tf
blark/transform.py:22: in <module>
    import apischema

    from apischema.json_schema.types import JsonSchema, JsonType, json_schema

    source, target = converter_types(
/opt/hostedtoolcache/Python/3.8.16/x64/lib/python3.8/site-packages/apischema/conversions/utils.py:35: in converter_types
    if target is None and is_type(converter):
/opt/hostedtoolcache/Python/3.8.16/x64/lib/python3.8/site-packages/apischema/typing.py:250: in is_type
    return isinstance(tp, type) and not get_args(tp)
/opt/hostedtoolcache/Python/3.8.16/x64/lib/python3.8/site-packages/apischema/typing.py:54: in get_args
    res = tp.__args__
E   AttributeError: type object 'dict' has no attribute '__args__'

So, an on-import failure inside of apischema before anything blark gets run. That makes it extremely likely to be an upstream issue, but it's difficult to confirm without being able to reproduce just yet.
