- apprt-gtk: Ghostty's runtime+build-time version gating (at_least)
with cargo features adw_1_3/adw_1_4/adw_1_5/gtk_4_16 (default on) and
the fallbacks for older libraries: MessageDialog (adw < 1.5),
clipboard dialog without SwitchRow, pre-Banner debug warning and
child-exited widgets, the old about dialog, GTK 4.16 CSS error source
bytes. The minimum stays GTK 4.14 / libadwaita 1.5 (Ghostty's floor).
The root build links with -z lazy so version-gated symbols don't keep
older libraries from loading.
- ghostty-helpgen (port of helpgen.zig) generates CLI action help and
keybinding action docs from doc comments at build time, replacing the
checked-in help/*.txt; +help and +list-actions --docs stay
byte-identical to Ghostty 1.3.1.
- ghostty-bench: libc wcwidth mode and separate simd/table and
uucode/table code paths like Zig.
- ghostty-cli: Windows branches of edit-config, list-colors,
list-keybinds and boo; ssh-cache DiskCache flock locking (no-op on
Windows, as in Zig) with an exclusivity test.
Test Plan:
- cargo test --workspace
- diff <(cargo run -q -- +list-actions --docs) \
<(ghostty +list-actions --docs)
README explains what the rewrite covers, how to build, run, install and
test it. ARCHITECTURE.md gains a top-down decomposition tree (binary ->
runtime/core -> termio/terminal/renderer -> leaf crates) and an updated
crate map with the actual internal dependencies, including the crates
added during integration (apprt, inspector, onig, bench, build-data).
CHANGELOG records the rewrite under Unreleased; no version bump.
Addresses the partial ports listed in
docs/rewrite/notes/review-completeness-codex.md (details in
docs/rewrite/notes/gaps-X2.md):
- Flatpak: the exit watcher no longer consumes the host command; a
shared FlatpakSignalHandle lets closing a surface still SIGHUP the
host process group.
- Child environment is byte-preserving end to end (ghostty_os::EnvMap
of OsStrings) and Snap paths are filtered like filterSnapPaths.
- argv handling no longer panics on non-UTF-8 arguments.
- URI percent-decoding keeps raw bytes; OSC 7 pwd is passed through
without lossy conversion.
- Keybinding comparison/hashing uses full Unicode case folding from a
table generated from CaseFolding.txt (Unicode 17.0.0).
- Link regexes set Oniguruma's whole-search retry limit through the new
minimal ghostty-onig crate (one SAFETY-commented FFI call).
- OSC 9 NUL-capacity check ordering matches Zig.
- Wayland registry binds/clears globals advertised after startup.
- Custom shaders may pass sampler2D to helper functions (naga adapter).
- +list-themes preview renders OSC 8 links, styled underlines and
follows color-scheme reports.
Also includes the inspector's integration edits in shared files
(renderer state hook, termio VT recording, core/apprt-gtk wiring), X1's
config/input/cli additions for completion generation, and a fix for a
race in the termio backpressure test (it wrote before `stty raw`
applied, so the cooked line discipline dropped bytes past MAX_CANON).
Test Plan:
- cargo test --workspace
- cargo clippy --workspace --all-targets -- -D warnings
Start of the full Rust rewrite of Ghostty 1.3.1 (reference source in
../ghostty). Sets up a workspace whose crates mirror Ghostty's Zig modules
(vt, unicode, datastruct, os, input, config, terminal, font, renderer,
termio, core, apprt-gtk) so porting work can proceed in parallel per crate.
Also adds:
- docs/rewrite/{ARCHITECTURE,PLAN,STATUS,AGENT_GUIDE}.md: crate map, core
design decisions (safe Rust, slab-based PageList, logical capacity
accounting), phased plan, progress tracker, and porting rules.
- Workspace clippy config relaxing pedantic lints that are pure noise for
low-level terminal code (casts, long functions).
- Shared vt types needed by several work packages up front: kitty
keyboard flags (kitty/key.rs) and the CSI separator bitset (SepList).
Test Plan:
- cargo test -p ghostty-vt (3 tests pass)
- cargo clippy -p ghostty-vt --all-targets -- -D warnings
