cmdr-pty

A websocket wrapper for a pty written in Go.

Connect to a terminal emulator front-end via websocket or server-side tcp socket. Originally developed for use with Terminal in UpDroid Commander.

Usage

go run . -a ":9990" -s "25x80"

See cmdr-pty --help for usage:

usage: cmdr-pty [<flags>]

Flags:
  --help              Show help (also see --help-long and --help-man).
  -p, --protocol="websocket"  
                      specify websocket or tcp
  -a, --addr=":0"     IP:PORT or :PORT address to listen on
  -s, --size="25x80"  initial size for the tty

Use websocket mode for direct connection between client-side in browser and cmdr-pty. Use tcp mode if you have another server-side application to connect via tcp port.

Resize the terminal by entering (rows)x(columns) into stdin.

If using with Terminal 0.1.1, make sure you export TERM=vt100 before running cmdr-pty since it does not yet handle some vt102/xterm escape sequences.

Contribute

Pull requests welcome! Though, I reserve the right to review and/or reject them at will. Can also file issues with the issue tracker.

TODO:

• Move resize and other command handling to another websocket endpoint for applications where access to the process' stdin is limited.
• Add more control options/enhancements.
