Pure CL terminal UI framework. No ncurses, no FFI, no external dependencies.

```lisp (ql:quickload :cl-tty) ```

## Quick start

```lisp ;; Create a modern terminal backend (let ((backend (make-instance 'cl-tty.backend:modern-backend))) (cl-tty.backend:initialize-backend backend) ;; Backend is ready — write text, draw boxes, handle input (cl-tty.backend:shutdown-backend backend)) ```

## Architecture

Two backends, one protocol:

• modern-backend — truecolor 24-bit, OSC 8 hyperlinks, DECICM sync, SGR mouse, kitty keyboard, bold/italic/underline, box-drawing chars
• simple-backend — ASCII art, no color, universal compatibility

Everything is pure escape sequences (no curses, no terminfo, no FFI).

## Backend features

Feature	modern	simple
Truecolor (24-bit)	Yes	No
Bold/italic	Yes	No
OSC 8 hyperlinks	Yes	No
DECICM sync	Yes	No
SGR mouse	Yes	No

## Development

```bash

sbcl –script run-all-tests.lisp

emacs –batch –eval "(progn (require 'org) (find-file \"org/FILE.org\") (org-babel-tangle) (kill-buffer))" ```

Literate programming: `.org` files in `org/` are the source of truth. `.lisp` files are generated by tangling.
