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.
