- 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)

# ghostty-bench: CodepointWidth / IsSymbol (compat-GC)
|
|
|
|
- `codepoint-width` modes (CLI as Zig: noop|wcwidth|simd|table):
|
|
- `wcwidth`: real libc `wcwidth` via a local `extern "C"` (no libc crate), in
|
|
a module with `#[allow(unsafe_code)]` + SAFETY comment. Zig does not call
|
|
`setlocale`, so neither do we (C locale). Non-unix: warning no-op like Zig on Windows.
|
|
- `simd`: new `src/simd_width.rs`, scalar port of `simd/codepoint_width.cpp`
|
|
(same range tables and precedence; vector lanes replaced by a sequential scan).
|
|
- `table`: generated two-stage table with the `<= 0xFF => 1` shortcut.
|
|
- `is-symbol` modes: `uucode` (default) = `is_symbol_computed`, computed from
|
|
private-use + block ranges (`computeIsSymbol`); `table` = generated symbols table.
|
|
Test verifies equality with the table over all codepoints.
|
|
- Cargo.toml: `[lints]` no longer `workspace = true` (workspace `forbid` cannot be
|
|
locally allowed); `unsafe_code = "deny"` and the clippy set is copied. Keep in sync.
|
|
- Deviation: Zig's `simd` falls back to uucode when built without SIMD; there is no
|
|
separate uucode width mode in the CLI (none in Zig), so none added.
|
|
- Tests: all modes run on a sample file; computed vs table symbols; simd vs table
|
|
samples; wcwidth ASCII. Zig `test CodepointWidth/IsSymbol` (run once, no data) covered by the run tests.
