What is libghostty-vt?

It is a standalone library extracted from the Ghostty terminal emulator that provides a high-performance, zero-dependency VT sequence parser and terminal state machine.

Which programming languages can use this library?

The library currently provides a Zig API for testing, with a C API planned for future releases.

Does libghostty-vt require libc?

No, it is designed as a zero-dependency library that does not require libc, making it highly portable and embeddable.

How does it achieve high performance?

It utilizes a 14-state DFA state machine with pre-computed transition tables and SIMD acceleration for plain text processing, reaching speeds over 100 MB/s.

Can I use this for production terminal emulators?

While it is the core of the proven Ghostty terminal, the standalone library version is currently in a 'not yet released' status (as of late 2025) but available for testing via Zig.

개발자 도구

Parses ANSI/VT sequences and maintains terminal state using Ghostty's zero-dependency, SIMD-optimized core.

Libghostty-vt is a high-performance terminal parsing library extracted from the Ghostty terminal emulator. It provides a standalone, zero-dependency DFA (Deterministic Finite Automaton) state machine capable of processing ANSI and VT sequences at speeds exceeding 100 MB/s through SIMD optimization. This skill assists developers in integrating Mitchell Hashimoto's embeddable terminal core into their projects, making it ideal for building terminal emulators, TUI frameworks, IDE terminal components, and cloud-based terminal environments without the overhead of libc.
