Terminal color codes do not work on Windows

[aramperes]

Color codes inside the console have stopped working for a while on my machine. I very well remember this
working correctly before, and it does work with other server platforms (e.g. Spigot).

Tested with commit be008ff. Perhaps this has been broken since a commit that upgraded the logging library, such as #859.

I am using Windows 10.

This is what I see in in CMD:

Similarly, in PowerShell:

This may have been fixed in 5b8b939 with jansi being upgraded to 1.17.1.

Still having the same issue on latest (cd89b6b)

Alright, we may have to wait until a new jansi comes out (as I see some progress on similar issues related to colors in the latest dev release), or for Glowstone to be upgraded to jline3 (though I believe jline3 just doesn't support colors on Windows last I checked).

I found two workarounds for this issue on Windows:

1. Windows 10 has a registry key to enable ANSI escaping by default. A step-by-step guide can be found here.

In summary, setting the registry DWORD HKEY_CURRENT_USER\Console\VirtualTerminalLevel to 1 will enable ANSI escaping by default for CMD. In PowerShell, it appears to simply ignore escaping (just shows plain color). Note: the regkey may not exist by default, so you will have to create it yourself.

2. Use an alternative console emulator that supports ANSI escaping. My personal favorite is cmder.
