Ability to sort literals

[timothycrosley]

isort should provide the capability to sort all common built-in non-complex literal types. Initially, it would only need to support non dynamic ones understandable by ast.literal_eval, but long term could support even complex definitions using ast parsing. Importantly the output format should be compatible with black by default and should be ran by any configured format function.

# isort: list
__all__ = ["b", "a", "c"]

would be come:

# isort: list
__all__ = ["a", "b", "c"]

There should be an additional option to dedup lists for the user (sets and others than are deduped within python should auto dedup):

# isort: unique-list
__all__ = ["a", "a", "b", "c"]

would become:

# isort: unique-list
__all__ = ["a", "b", "c"]

This supersedes #392

This is finished in develop and will be released in the 5.3.0 release.

Hello @timothycrosley!

Sorry for the silly question, but I'm having trouble finding how to turn this functionality on within isort. I was unable to find any references to literal or __all__ within the options, and my manual reading/skimming didn't come up with anything obvious.

Is it possible to turn on sorting of __all__ via the isort CLI?

@blthayer Have you found out how to sort __all__ meanwhile?

@blthayer Have you found out how to sort __all__ meanwhile?

@jugmac00 - I have not, unfortunately. I just sort of dropped it as "not worth it for now" 😄

Good luck, and if you find something I'd love to hear about it!

Looks like I figured it out 😉
