Thanks for the issue, you are right windows terminals are not supporting attributes. Not sure what you mean with 'partial attributes'. The link you sent is about the ANSI escape codes which could be used for Windows 10 systems. Currently, crossterm already uses ANSI escape codes instead of WinApi for Windows 10 systems.

Could you elaborate more on what you mean with 'partial support' or 'partial attributes'?

As in, unless I'm understanding this incorrectly, this shows that it supports bold (among others):

Ah, yea now I see. I did never saw those options in the document, must have overlooked them. This is actually really cool and will be implemented of course. Thanks for creating this issue and letting me know.

Just for issue record:

The following attributes are needed to be implemented.

Value Description Behavior
0 Default Returns all attributes to the default state prior to modification
1 Bold/Bright Applies brightness/intensity flag to foreground color
4 Underline Adds underline
24 No underline Removes underline
7 Negative Swaps foreground and background colors
27 Positive (No negative) Returns foreground/background to normal

Currently, this is already working for UNIX terminal and so it is just a matter of removing some #[cfg(unix)] attributes from the following methods. So that windows systems are also able to call those style methods.

Hm, I might be wrong.
While it says it supports it, the terminal would disagree...

Ok, nevermind.
I missed the foreach loops when I was removing the cfg(unix)s.
It works now, but my god, it's barely visible...
It's basically just more... white....

That's strange lol. However, how is Underline etc. doing?

This is the final result with the PR I just made (Excluding the double "Bold Text". I had a duplicate line...).
