Screen: A Pure PHP Terminal Emulator for Rich Text UIs

Screen is a terminal emulator library written entirely in PHP, enabling the creation of rich text-based user interfaces within any PHP application. Initially developed to solve ANSI escape code conflicts in Solo for Laravel's multi-process TUI, Screen creates a virtual terminal buffer to safely handle ANSI operations (cursor movement, color changes, screen clearing). This ensures consistent rendering and supports Unicode, multibyte characters, scrolling, and a wide range of ANSI escape codes. A comprehensive test suite, featuring a novel visual comparison system, guarantees accurate emulation.
