draft: Add codespell CI job and fix some typos

[cbm755]

• add a codespell action
• clean up some typos
• possibly set it to warn only instead of error
  • probably unnecessary as I've fixed most of them

Basic idea here is to run codespell on all merge requests. There are two files to place exceptions in, but in my experience these are rare and it generally does a good job, fixing more things than the hassle of the occasional exception.

I have excluded the tests/ dir b/c there are lots of false positives there (mostly b/c of non-English text). It should be fairly self explanatory how to exclude other directories in the future if you need.

@JorjMcKie Do you know what "parm angle" means here? does it mean "reduce angle parameter by"?

            betar -= w90  # reduce parm angle by 90 deg
            alfa += w90  # advance start angle by 90 deg

edit: I went ahead and removed that comment, seems a little WET anyway.

[cbm755]

Only two more errors where I'm uncertain what change to make (see above).

After we make those, this is ready to go!

If you like feel free to move the job to some other .yaml file.

Did I break this test somehow?

Thanks for this PR, i hadn't come across codespell before, and it looks to be doing some very useful checking here.

I think there's a trivial indentation error in the patch that's causing the test failure.

I think we should run codespell as part of the existing pytest test suite, alongside pylint and flake8, rather than only has a Github action. I can make that change but alternatively feel free to add a new file tests/test_codespell.py in your PR, similar to tests/test_pylint.py and tests/test_flake8. We'll also need to add codespell to scripts/gh_release.py:test_packages.

Thanks @julian-smith-artifex-com I think I've done those changes but the test is still failing :(

Is it clear to you what that change was? thanks!

[cbm755]

Would you like this rebased and some of my small testing commits squashed into cleaner commits?

There's an error message from test_quick:

2024-05-22T17:54:04.4106750Z E     File "/tmp/tmp.9IvmIxA8FB/venv/lib/python3.12/site-packages/pymupdf/__init__.py", line 11304
2024-05-22T17:54:04.4107721Z E       raise ValueError("radius must be positive")
2024-05-22T17:54:04.4108315Z E   IndentationError: unexpected indent

So init.py", line 11304 is indented incorrectly in your branch i think?

[julian-smith-artifex-com]

Apologies for taking a while to look at this again.

Things that need updating:

1. Fix indentation error src/utils.py:11304. Hopefully test_quick will then pass.
2. Remove running of codespell from test_quick.yml - not needed now it's a standard test.
3. Could we remove the small .codespell* files and pass the excludes on the command line from the test fn?

I'd be happy to do some/all of these (preserving your name in the commits) if that's easier, but equally happy for you to do things.

Thanks.

I've taken the liberty of extracting your commit with the new codespell test into a new PR #3656.

This has a smaller set of fixes, with a view to getting a PR for codespell (codespell-project/codespell#3476) accepted which will allow us to mark multiline regions of input files to be excluded from codespell checking.

thanks and sorry for not getting back to you with revisions. Happy to see it merged.
