feat: allow python prefixed strings (f,b,r,u) with single quotes

[ribru17]

Fixes #376

Allows autopairing of single quotes after f, b, r, u (and the capital variants).

Hi! I am just a random user. Just to let you know, I tried your version and behavior is still inconsistent for me.
input f"{ -> f"{}"
input f'{ -> f'{'}
If you don't mind please try that and tell me if that is something that still needs to be fixed or maybe that's just a problem with my config.

Ahh, thanks for pointing this out :/ The issue I have found is that the check is_in_quotes fails (line 72) because there is a check that this will return false for single quotes following a word (to prevent it from thinking an apostrophe means it is inside a quote). I found a solution but I don't think it is a good one, it just hardcodes this part to pass when in Python. I think I will wait and see what @windwp thinks

Can you add testcase.

I agree with you about modify function isinquote for python is not good.

You should create it from scratch with Rule.
or you can use a second parameter on with_pair to replace a a condition function with your function

[ribru17]

After working a bit, now I think it is not as easy. The bracket issue breaks due to the bracket rule thinking it is not in a quote (even though it is in this new case). So there would have to be some sort of change to the is_in_quotes function. However it may not be as bad as a Python workaround hard code. Maybe the function can take some optional parameter to override the regex with a new regex (e.g. the python prefixed string checker)?

@ribru17 Are you try to change the order of rule if you put your rule with f string first.
then you add rule is_in_quote . then i think it should work

@windwp Sorry not sure what you mean by that
