Support --exclude more than once on command line #11329

Description

Support --exclude more than once on command line

The result is an "OR" of all the patterns provided.
Should be fully backward compatible to existing folks.

Test Plan

Added tests for the new behavior to test_find_sources.py. Also did a quick manual test to make sure command line arguments are working ok.

Thanks for working on this, maybe config is parsing it as a string still?

nipunn1313 · 2021-10-14T21:55:59Z

Yep - when I add it to setup.cfg, it's parsing as (using ibis as an example)

[mypy]
exclude = versioneer.py

as

['v', 'e', 'r', 's', 'i', 'o', 'n', 'e', 'e', 'r', '.', 'p', 'y']

I added four integration tests that should help cover this case and fixed the issue.
Good on mypy_primer!!

this actually seems bad - because commas can appear in regular expressions. Perhaps we need another way to delimit multiple entries? Is there precedent?

Per #10310 (comment) - I opted to go for newline separated list of regexes and updated the docs

Hiya - wanted to check in w/ the maintainers on this one again (no rush - just want to make sure it wasn't forgotten)

hauntsaninja · 2021-10-22T05:14:27Z

Thanks, this is great!

It would be awesome to get a release that contains this fix.

python#11329 added support for nicer `exclude` lists TOML has a built-in list syntax, and it would be nice to use that for specifying lists for the `exclude` option. This change tries the ini-style first: if `exclude` is set to a multiline string, it will split that on newlines, otherwise it will assume it's a list.

For anyone following along at home, this does not appear to have made it into today's release of mypy 0.920.

posita · 2021-12-22T21:40:42Z

How do these get represented in pyproject.toml? Could this be related to #11825?

Possible root cause for #11825?

Yes - seems likely. Good find. The config_parser uses very basic newlines to split apart different excludes.

The behavior is documented in the config_file.rst - about multiple patterns in a newline separated manner.

Didn't realize that multiline excludes like this were an old pattern
Suggestion on what to do to fix?

Didn't realize that multiline excludes like this were an old pattern

To be fair, I don't know if that was ever official. It was more of a work-around that folks discovered because they (probably like you) were desperately seeking a fix for #10310.

config_parser.py is new to me, and I'm still trying to digest it. At a high level, I'm wondering if one can treat .toml files differently? It looks like there's a mechanism to do that, but I'm still trying to figure out if it's sufficient for what I have in mind, i.e., in a .toml file, if it's a string, just parse it as a single regex, but if it's an array, treat each item as its own regex? (Just thinking out loud here.)

~~Looking further, I think this might be as simple as appending the following here~~:

toml_config_types.update({ # … 'exclude': try_split, })

UPDATE: Nope. No. That would still try to split strings along commas.

Dunno what testing looks like yet, though….

If I know you, you're probably ¾ done with a PR by now, but if you haven't started, I can take a stab….

I haven't started. Go for it!
Appreciate the compliment :)

I haven't looked at the details, but there's also this PR that was opened recently: #11746

Thanks for the heads-up @hauntsaninja! I don't think that one works. I'll comment there.

#11828 is up. I commented on #11746.
