bittty

A pure Python terminal emulator library. Board is an embeddable, headless emulator core; the demo and textual-tty provide terminal frontends.

It was written as an alternative to pyte, and currently does not have a graphical front-end.

Demo

Run the standalone demo:

python ./demo/terminal.py

Or use the textual demo to see it in a TUI:

uvx textual-tty

Do wtf you want, but don't blame me when it rips a hole in your trousers.

Known limitations

• There is no scrollback buffer or reflow on resize.
