Ghostling — libghostty Terminal Emulator

Skill by ara.so — Daily 2026 Skills collection.

Ghostling is a minimal viable terminal emulator built on libghostty-vt, the embeddable C library extracted from Ghostty. It uses Raylib for windowing/rendering and lives in a single C file. The project demonstrates how to wire libghostty-vt's VT parsing, terminal state, and render-state API to any 2D or GPU renderer.

What libghostty-vt Provides

VT sequence parsing (SIMD-optimized)

Terminal state: cursor, styles, text reflow, scrollback

Render state management (what cells changed and how to draw them)

Unicode / multi-codepoint grapheme handling

Kitty keyboard protocol, mouse tracking, focus reporting

Zero dependencies (not even libc) — WASM-compatible

libghostty-vt does NOT provide: windowing, rendering, PTY management, tabs, splits, or configuration.
