Help with 256 color support on Windows

Issue

Hi,

I would like to be able to use full 256color in Hyper. Setting the env variable TERM to xterm-256color displays colors perfectly.. but it breaks the functionality of the "clear" command. Is there some other way I can accomplish displaying the colors properly while retaining functionality of clear?

[lijunle]

Another issue with TERM=xterm-256color, the vim will mess the screen content with the editing content.

[sanguine8082]

Windows Command Prompt does not support 256 colors :cry:

You will need to use a different terminal, like Git For Windows or Msys2 to get 256 color support, and then point hyper.js to their respective executable.

[chiefjester]

I thought they supported 24-bit already?

I think Windows 10 might have support, but not before that.

[Xapphire13]

Windows 10 does support 256 colors as of TH2, see here

When running AnsiColors256.ans via type AnsiColors256.ans in PowerShell I get:

But running the same command in Hyper I get:

Same issue here, is a fix underway ?

I have issue with this git config for diffs

[color "diff-highlight"]
        oldNormal = red bold
        oldHighlight = red bold 52
        newNormal = green bold
        newHighlight = green bold 22

[chabou]

@tdurand can you confirm me that you are on Windows?

[chabou]

Using GitBash with Hyper (2.0.0-canary.10), this is what I get when running AnsiColors256.ans :

And WTF, my mouse pointer goes UNDER the grey zones... 😱

(It works well on macOS)

[tdurand]

Yes, i'm on Windows 10 using WSL with Ubuntu. And the color works well if you use the powershell terminal, so I'm pretty sure it's an issue of hyper.

[chabou]

Yes, an issue with Hyper (but only on Windows, from my testing).

[kaminooni]

I ran into the same problem. And since I use vim (with a lot of color schemes) for coding, it makes hyper almost unusable 😞

[dougmaitelli]

Even worse here:

Related? #2327

[Macmee]

any movement on this issue?

[dougmaitelli]

I did a lot and research, testing. It seems it is not a Hyper issue. It is a node-pty issue because of a limitation in the way they interact with processes on Windows. So basically it seems to be still a Windows limitation.

You can even confirm this because the integrated shell in vs code has exactly the same issue, and they even use winpty instead of node-pty.

[skegel13]

I am guessing as well it's not necessarily a Hyper issue since it occurs in VSCode as well as ConEmu. I am wondering though how Git Bash by itself or PuTTY does it. I can open Vim locally or when I ssh into a server with no issues. If I run Git Bash in Hyper though, I get the color issues.

[scottbilas]

ConEmu supports 256 and true color. Needs a bit of config.

https://conemu.github.io/en/Xterm256Colors.html

It works via a hook dll that monitors direct calls to write to the console, processing escape codes etc. There's also quite a lot of special case code, including detection of the vim process and powershell.

[szmarczak]

Any news?

[florisvaneck]

I would appreciate an update on this! Really harming my otherwise fantastic Hyper experience on Windows! Not seeing this issue in Hyper on Ubuntu (VMware).

I am using the hyper-solarized-dark-highcontrast theme to make it slightly less worse.

[albinekb]

This is a windows issue @florisvaneck, not much we can do.

[szmarczak]

Hyper 2.0.0 stable:

[Stanzilla]

That's https://github.com/xtermjs/xterm.js/issues/484

[Tyriar]

@Stanzilla this is not actually xtermjs/xterm.js#484, that's for truecolor (16 million) color support. 256 color support in Windows is due to winpty: https://github.com/Microsoft/vscode/issues/45693

[dvf]

Has this been resolved?

[Xapphire13]

@dvf, nope the issue is still repro

[panda2134]

repro again on windows 10 build 1803 with hyper 2.1.0-canary2

[jasonxoc]

Ohh I should have searched for this issue before taking the time to make this:

Man, windows terminal emulation sucks SOOO bad. Nothing but issues with drawing, color support, mouse support with tmux and vim. ... Hoping I can finally get gnome-terminal to work at some point.

[Josema]

Any news?

[monsterkodi]

This is related news: https://github.com/Microsoft/console/issues/57 A lot of console problems will probably be solved this fall/winter.

[Tyriar]

More specifically for hyper: https://github.com/Microsoft/node-pty/issues/216

[monsterkodi]

Better 30 years late than never :-)

[prinsss]

Same issue here, Hyper 2.0.0 on Windows 10 1803. Any news?

[Tyriar]

@printempw I'm working on Microsoft/node-pty#216 which is expected to fix this, ETA is still a while off though.

[duemti]

Pardon me, but why SSH to virtual machine also doesn't display colors? I don't think it's WSL specific bug. Heck, it even in windows environment doesn't print colors right.

Here Hyperterm at the left and GitBash at the right.

[Tyriar]

This can be marked as fixed when Hyper adopts node-pty@0.8.0 https://github.com/Microsoft/node-pty/releases/tag/0.8.0. To be clear, it will not work for < Windows 10 1809 and non-WSL may or may not work.

[duemti]

Thank you very much for hinting. Updated windows and on Terminus terminal it show all 256 colors. For those wondering, install it with npm: npm i terminus-terminal

That's not a solution for hyper though. Anyway thanks for pointing out a nice alternative.

[RReverser]

This can be marked as fixed when Hyper adopts node-pty@0.8.0 https://github.com/Microsoft/node-pty/releases/tag/0.8.0.

This was now done in https://github.com/zeit/hyper/pull/3329, so I suppose the issue should be fixed?

[auslander]

Updated to Hyper 3.0.0 Canary 6 and still having the issue. Been fighting this off and on for months and just found this thread today. Thought I was just doing something wrong.

[szmarczak]

Yup, still doesn't work. Latest Windows 10 and canary 6:

[duemti]

Actually it works. Probably you need to update your Windows 10 to build 1809 or higher.

[szmarczak]

Probably you need to update your Windows 10 to build 1809 or higher.

I'll give it a try. I've been putting off some updates for a few days due to some important work. I'll inform you later, thanks :)

[auslander]

Thanks for the update. Going through now and attempting to apply the 1809 update manually using the tool at microsoft.com. I had assumed windows update was automatically pushing the October update by this point but was mistaken. Trying now.

[Tyriar]

FYI there are several issues in Windows 1809 and I moved the default minimum version in node-pty to what is the current fast ring Windows Insiders build, so you should get this in windows 1903.

[szmarczak]

So we have to wait a lil bit more...

[heamaral]

I've updated my windows to test it, and it works. But clear isn't cleaning the buffer:

and caret doesn't hide when interacting with some interactive application:

[szmarczak]

After I've updated my Windows it works as expected :tada:

[MortezaRamezani]

It still doesn't work with msys2 on the latest version, mintty with msys2 works fine.
