Research direction

No implementation file or test is named. Reproduce the report in VS Code 1.62.3 on Windows with the supplied Python snippet, then trace the syntax-highlighting grammar used by MagicPython. Done means function annotations in the example receive the expected highlighting without regressing the surrounding function syntax.

Description

Hi there,

My VSCode does not work well on highlight syntax with python function annotation. Details are following:

  • Editor name and version: VSCode version 1.62.3

  • Platform: Windows 10

  • Color scheme: Any (primary using Tokyo Night theme)

  • MagicPython version: latest

  • A sreenshot:
    image

  • 5-10 lines of surrounding code:

def gcd(a: int, b: int) -> int:
    if a == b:
        return a
    else:
        if a > b:
            return gcd(a-b, b)
        else:
            return gcd(a, b-a)


def gcd2(a: int, b: int):
    if b == 0:
        return a
    else:
        return gcd2(b, a % b)

Any ideas?

Thanks
