Python: Not needed syntax highlighting for string literals

[jonvanausdeln]

Currently Positron and VSCode still add syntax highlighting to string literal:

In this case, bar is a string literal and will gets automatically escaped correctly by python. I would like to see it not highlight the missing escapes, similiar to how PyCharm does it.

This probably would involve contributing to Jedi (?) upstream.

This is defined in the Python grammar:

positron/extensions/python/syntaxes/MagicPython.tmLanguage.json

Line 1 in cae259e

{

.

Which is vendored from this repo: https://github.com/MagicStack/MagicPython.

I see there's an issue there for this case: MagicStack/MagicPython#259.

This is apparently a feature 😅 MagicStack/MagicPython#114 (comment):

This is a feature.

foo = r'\nregexp'  # this is parsed as a "regexp-string"
bar = R'\nregexp'  # this is parsed as a raw string

I struggled against this issue for a while coming from PyCharm to VSCode. Using some resources found online for editing TokenColorCustimizations and TextMateRules in the JSON settings, I was able to create a custom workaround at the link below. It's annoying having to manually enter hex codes for the colors to all match the way you'd expect inside of an r-string, but unless you are a person who changes themes often you should only have to make the edits once.

Instructions for adding the code to your VSCode user settings are contained in the .txt file here:
