Description

Numbers like 100_000_000 aren't properly highlighted (see PEP 515 specification). This should be pretty easy to fix, just edit these lines in the grammar. I tried to fix this myself, but wasn't able to get atom dev running.

Steps to Reproduce

1. Put 10_000_000 in source code.

Expected behavior:
Proper highlighting

Actual behavior:
Number highlighting stops in the middle of the number

Reproduces how often:
100%

Why isn’t it fixed yet? Easy to do

Are there any updates on this one?

[winstliu]

@kac487 do you know if this is happening with the Tree Sitter grammar, or just the non-Tree Sitter one? (If you don't know, that's fine)

[kac487]

Sorry, I don't know which one it is.
