Windows use case? #387

Closed JPHutchins closed 6 months ago

JPHutchins commented 6 months ago

Since Windows Terminal supports ANSI escapes, I am curious if colorama disables itself in use cases where it is redundant? Like it would for Linux, for example.

What exactly are the terminals on Windows that still require colorama?

I want to make sure that my packages have good compatibility but I'm not thrilled to support every ancient Windows console!

Thanks, JP

Does this section of the docs answer your question clearly? If not can you suggest edits that would make it clearer?

Yes, thank you! It seems that in most cases the code will follow the path eventually to enable_vt_processing:

https://github.com/tartley/colorama/blob/136808718af8b9583cb2eed1756ed6972eda4975/colorama/winterm.py#L178-L195

This calls the Windows API defined here: https://learn.microsoft.com/en-us/windows/console/setconsolemode

In the vast majority of (modern) cases this is basically a no op because the terminal already has the ENABLE_VIRTUAL_TERMINAL_PROCESSING flag set and colorama will not impact expected ANSI processing.
