Resolves the parity items of docs/rewrite/notes/review-rv17-codex.md (final-Z20.md): - FreeType-only font backend is also available on Apple targets (discovery-free, embedded emoji fonts); ghostty_surface_quicklook_font returns null for every backend except plain CoreText like Zig. - The +list-fonts test keys off the font crate's selected backend (HAS_DISCOVERY), correct under feature unification and on Apple. - Inspector font: 32 px rasterized with FreeType (dear-imgui freetype) like Ghostty; a new `visual-parity.sh inspector` scenario shows 0.031% differing pixels (hover highlight) vs the original on Linux. Windows, Apple and wasm keep stb_truetype at 32 px (registered as a deliberate deviation). - Inspector DCS/APC descriptions follow Zig 0.15.2's formatting (checked by running Zig), incl. the terminal.Parser.Action prefix. - The ImGui demo window appears only in dev-profile builds, mirroring Zig's .Debug-only gate. Test Plan: - cargo test --workspace --no-fail-fast (3582 passed) - just check-macos (both, also with --features font-backend-freetype) - scripts/visual-parity.sh inspector
ghostty-rs
A Rust rewrite of the Ghostty 1.3.1 terminal emulator for Linux (GTK4 + libadwaita, OpenGL).
It aims for behavioural parity with Ghostty: the same configuration file
format, options, defaults and documentation; the same keybindings and
actions; the same ghostty +action CLI; the same terminal emulation
(including kitty keyboard/graphics protocols, OSC 8 hyperlinks, semantic
prompts, synchronized output, tmux control mode); the same shell
integration, themes and terminfo.
Out of scope: macOS, Windows, WASM, the embedded libghostty C API, and
Sentry crash reporting (disabled by default on Linux upstream).
Building and running
Requirements: Rust (edition 2024), GTK ≥ 4.14, libadwaita ≥ 1.5,
fontconfig, freetype, harfbuzz, Oniguruma, libepoxy, blueprint-compiler
and glib-compile-resources at build time.
cargo run # open a terminal window running your shell
cargo run -- -e htop # run a command
cargo run -- +list-themes # CLI actions work like Ghostty's
cargo run --profile production # optimized build (LTO, no debug assertions)
Development builds find resources/ (shell integration, themes, terminfo)
automatically. Your existing Ghostty config
(~/.config/ghostty/config[.ghostty]) is used as-is.
Installing
just install /usr/local # binary, share/ghostty, terminfo, desktop files,
# completions, man pages, translations, icons
just install /usr false true # system-package layout (lib/systemd/user)
Testing
just test # cargo test --workspace (~3000 tests)
just clippy # clippy with -D warnings
Every Zig test block of the ported files was ported to a Rust test.
crates/ghostty-core/tests holds end-to-end tests that drive the real core,
terminal and a real pty through a fake app runtime. ghostty-bench mirrors
Ghostty's benchmark tool; terminal stream throughput is on par with the Zig
build (see docs/rewrite/notes/perf-P1.md).
