Ports ZIG/src/crash/* as crates/ghostty-crash. Like Ghostty (which uses sentry-native only to write local files), crashes are written as Sentry envelopes (<uuid>.ghosttycrash) to $XDG_STATE_HOME/ghostty/crash: - envelope parse/serialize (all Zig tests ported) - panic hook plus SIGSEGV/SIGBUS/SIGILL/SIGFPE/SIGABRT handlers on an alternate stack; the signal path is allocation-free and re-raises with the default action so exit status and core dumps are unchanged - thread-local crash context (main/renderer/io/read thread, surface dimensions) set from the corresponding threads - `sentry` cargo feature on the root binary, off by default like upstream's -Dsentry; +crash-report lists exactly what is written Deviation: attachments always carry "type":"attachment" (Zig's in-memory attachments omit it and become unparseable). Test Plan: - cargo test -p ghostty-crash (19) - cargo test --test crash (child panics, SIGSEGV, stack overflow and abort each produce a valid envelope listed by +crash-report)
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).
