Terminal emulation and tools powered by libghostty-vt.
Builds minimal C terminal emulators using libghostty-vt for VT parsing, state, and rendering API, with Raylib for windowing. Covers init, PTY input, keyboard, and render state wiring.
References terminal docs on TTY/PTY, streams, signals, escape sequences, job control, redirection, Windows consoles, and cross-platform patterns for console/shell development.

Terminal emulation and tools powered by libghostty-vt.
"libghostty-vt is a zero-dependency library that provides an API for parsing terminal sequences and maintaining terminal state" — Mitchell Hashimoto
A C-compatible library extracted from Ghostty for embedding terminal emulation:
| Feature | Description |
|---|---|
| Zero dependencies | No libc required |
| SIMD-optimized | Fast parsing of escape sequences |
| Unicode support | Full UTF-8/grapheme handling |
| Memory efficient | Optimized for embedded use |
| Fuzz-tested | Valgrind-verified, production-proven |
