tmux fails to start in local session #7159

@DHowett-MSFT commented on GitHub (Mar 26, 2020):

This is almost certainly a Cygwin runtime issue, as it’s failing to detect that the windows console host is attached. MinTTY is somewhat of a red herring- it has a special handshake that it does with Cygwin to assume terminal responsibility.

How are you launching your Cygwin profile?

For Cygwin I do (it is the same with bash):

"commandline": "C:/cygwin/bin/zsh.exe --login -i",

For MSYS2 (but it is Cygwin in disguise, so probably the same issue)

"commandline": "C:/MSYS/msys2_shell.cmd -defterm -no-start",

MinTTY is somewhat of a red herring- it has a special handshake that it does with Cygwin to assume terminal responsibility.

I understand that. I report here, because it would be nice to make it work in WT. But if you tell me that it need to be fixed on Cygwin side I guess I will redirect my request to them.

I did quick test with ConEmu and it has the same issue,

Ugh, I may have fire to fast with reporting this issue. It seems to be known issue.

Thanks for following up with all those other issues! Looks like there's a pretty broad problem across terminal emulators on Windows. Do you know if there's actually an upstream bug on cygwin that's tracking this bug? I'd love to resolve this issue as a dup of the upstream one, but I want to make sure the diligence is done ☺️

I searched their ML and there seems to be no report about this specific issue. They don't have public bug tracker except mailing list. I will send them mail and see what they say.

Since this looks pretty widespread, I'm gonna close out our copy of it. I'd definitely watch their mailing list, though, if I had a link to an ML archive for this report 😄

After all I forgot to link here upstream report: https://sourceware.org/pipermail/cygwin/2020-March/244192.html Unfortunately, it went nowhere.

Sometimes you need to fix things by yourself... maybe when I feel the need for tmux again.

And explanation why this actually happens. https://cygwin.com/pipermail/cygwin/2020-May/244878.html

For those who wish to use Windows Terminal + Cygwin + tmux, there is a workaround. It's not a very elegant one, but it appears to work.

Use the following command line in the Windows Terminal profile to start Cygwin:
C:\Cygwin\bin\sh.exe -lc "exec dtach -c /tmp/dtach-shell-$$ -Ez /bin/bash -i"

For this to work, dtach must be available in Cygwin. Unfortunately, Cygwin does not provide a binary package. Fortunately, dtach is very small and easy to build from source.

Update

Tested both ConEmu and Cmder, they do NOT have this issue. CC @kasper93
Found 2 workarounds for Windows Terminal + MSYS2. CC @sfzhi
1. Run tmux with this command: script -c tmux /dev/null. Source. CC @csdvrx

Thank you so much @kasper93 @changyuheng @sfzhi for the research done and workarounds.
(I will always be thankful to windows terminal team).

TLDR : script.exe actually comes with util-linux package (msys2)

it may be already known, but commenting here just to save time for someone like me who is
searching for script.

I was wandering around the internet for months to get tmux
working in windows terminal (without wsl)

For anyone who wants to get windows terminal+ git bash+tmux without installing full package of cygwin or msys, we can do so by getting just tmux and script binary from msys packages (check once in the msys package page to verify if you already have its dependencies) and putting the so got files in respective folders of C:/Program Files/Git.

If you are using the script screen or dtach workaround:

You'll need to export a couple of environmental variables in your .bashrc or .zshrc files to get your cool fonts working:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

@changyuheng The statement that you tested ConEmu is pretty vague. I can say that if I try to run cygwin tmux from cmd.exe or cygwin bash in ConEmu, I get the same error as Windows Terminal. If I host a mintty session in ConEmu, I can run tmux, but then I'm running a different terminal emulator that is known to work.

~~How exactly do you get it to work. I copied the binaries but still I get the open terminal failed: not a terminal on Git Bash~~

After you copy the binaries from C:\msys64\usr\bin to C:\Program Files\Git\usr\bin I used this alias stollen from netheril96

# placed it in ~/.bash_profile for both GIT BASH and MYSYS2
tmux() {

The thing is still not fixed, wow.

On top of that, .tmux.conf doesn't work at all, and things need to load using the script method. Example: https://github.com/srouquette/msys2/blob/master/home/Syl/tmux.conf.sh
