Executing a command doesn't work with zsh

Executing a command doesn’t work with zsh. In zsh a new line is added to the command line, but it’s not executed. A manual press of Enter is necessary to execute.

Details

• Browser and browser version: Chrome 103
• OS version: Ubuntu 20.04
• xterm.js version: 4.19.0 (what is shipped with ttyd 1.6.3)

Steps to reproduce

Executing a command seems to only work with bash, not zsh:

window.term.paste('ls\n'); # bash only
window.term.paste('ls\r\n'); # bash only
window.term.paste('ls\r'); # bash only
window.term.write('ls\n'); # neither works
window.term.write('ls\r\n'); # neither works
window.term.write('ls\r'); # neither works

Any idea how this can be achieved with any shell?

What you are looking for, is to write to the datasink you are also forwarding term.onData(write_to_datasink) too. You just need to do write_to_datasink('ls\r'), should work with all shell types.

Just call your onData function with the command you want and your done. No need for term.paste or additional keyboard libs on top.

Works for zsh

import "keysim"

terminal.paste(command);

// use keyshim to send enter key
var input = document.querySelector('textarea');
var keyboard = Keysim.Keyboard.US_ENGLISH;
keyboard.dispatchEventsForAction("enter", input);
