Sorry, I tried to use this function. (It was running on my local machine. Generating the files correctly).
But, I replaced for manual configuration, since it's breaking in CI tests.

Because you used list[tuple], which is only supported in Python 3.9+. Before that, you need to use typing.List. In any case, we don't use type annotations in our code base, and the inlined version is just as readable IMHO.

Thanks for the patch!

A lot of comments, but nothing major.

[birkenfeld]

this one is not used (another danger of using too many trivial states...)

[RickBarretto]

• remove additional state
  • I tried to just remove constants state, but I think the commit bellow is better
• remove the high amount of trivial states
  • I just removed that amount of states, put on constants, and added side notes. I think it's better.

[birkenfeld]

There's still a few of them (punctuation, sugar, builtin-predicate-functions, maybe more...)

[RickBarretto]

• remove trivial states
• move predicates to builtin_functions
• remove string-content-multi-line state
• remove strings state
• remove comments state
• remove constants state

[RickBarretto]

@birkenfeld, do you think I need to remove operators state?

[birkenfeld]

"need to" is too strong, but in general states that are only used as an include once are not technically needed.

[RickBarretto]

Sure!

[RickBarretto]

Note: I'll test the file. Some of this changes may break something.

[RickBarretto]

@birkenfeld. Can You help me with something?

So, in these lines I have string interpolation string-interpol and string templates string-templates. But, templates are working and interpol doesn't.

They are almost the same, except for the notation. Templates start with <|| and end with ||>, while interpolation starts and ends with a | only.

Templates (working well):

String Interpolation (broken):

What should I do in this case?

[RickBarretto]

Error:

W117: Overlap in character class: ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
              (r'\b\\[\w\d]+\b\??:?',                 # array index
                     ^ here

The \w metacharacter matches word characters. A word character is a character a-z, A-Z, 0-9, including _ (underscore).

My bad! I think it'll run now!

[birkenfeld]

Looks nice now, thanks!

Added changelog and fixed up code style a bit in a followup commit.
