Zsh in tmux in connector is broken #22

Closed rcx closed 5 years ago

rcx commented 7 years ago

Versions

ConEmu build: 170805 x64 OS version: Windows 1607 x64 14393.0 (LTSB) Used shell version zsh in tmux, in wslbridge wslbridge: from wsltty 1.7.9 Connector: v1.2, x64 cygwin

Problem description

Output in zsh above the current prompt is invisible.

Steps to reproduce

  1. Start ConEmu using task:

    @echo off
call SetEscChar
echo %ESC%[9999H
set PATH="%~dp0;%PATH%"
"%~dp0..\conemu-cyg-64.exe" "%~dp0\wslbridge.exe"

    Task: cmd /c run.cmd -new_console:h9999 -new_console:p5nam:/mnt

  2. Start tmux.

  3. Start zsh. (Blank .zshrc and .tmux.conf)

The problem occurs when zsh is run through the ConEmu connector and wslbridge but does not occur when run through wslbridge only. The issue does not occur in zsh only. It occurs when running zsh in tmux. The issue does not occur without the connector, the connector seems to be the issue. Also running bash in zsh in tmux in wslbridge in connector works normally. I don't know why zsh is weird.

Actual results

Output in zsh appears for a brief moment and then immediately disappears. The prompt moves down as expected, however the output above it does not show up. It remains in scrollback. Interestingly enough the output begins to show when it reaches the bottom of the buffer, but only then.

Expected results

Output in zsh should be visible.

Update: I've hacked together a solution by prepending %{\e[9999H%} to my zsh prompt for when I use wslbridge. This forces the prompt to grow from the bottom up rather than top-down. A bit jarring but better than no output.

Connector and wslbridge are now integrated into ConEmu distro.

On your screenshot I don't see StatusBar, I'm interested in columns 'Terminal modes', 'Console visible rectangle' and 'Console buffer size'.

When you run tmux the height of ConEmu (you set it to 9999 by -new_console:h9999) is disabled - tmux process all backscroll internally.

One more question - is there a text or it is just invisible (black on black). You may check that by selecting console contents.

Selecting in tmux makes the output come back (??). Very strange.

Modes: XACM

This issue is misleading.
