Resolves the 6 differential gap groups in docs/rewrite/notes/review-
rv9-codex.md (details in final-Z11.md):
- ghostty_os::zig_fmt ports std.fmt.parseInt/parseUnsigned/parseFloat
(underscores, 0x/0o/0b prefixes, hex floats, inf/nan) with the Zig std
tests and replaces every int/float parse in config, keybind
parameters, ssh-cache and desktop detection.
- Interior NUL no longer panics in font names and ends C strings like
Zig's backing bytes (fontconfig, C config getters, title actions,
clipboard callback, relative paths, config-file, shaders, background
image, GTK CSS).
- GTK new-window arguments are trimmed of ASCII whitespace only.
- Command tokenization uses a port of std.process.ArgIteratorGeneral
(incl. CR/LF separators) with its std tests.
- UTF-8 validation happens where Zig's field parsers do it, so error
kinds match (metric modifiers, quick-terminal size, link, ...).
A scripted differential run of 202 fields x ~220 hostile/valid values
against /usr/bin/ghostty (+validate-config and +show-config: exit code,
stdout, stderr) now has zero mismatches besides build-specific defaults
(theme resources path, auto-update-channel, gtk-opengl-debug); it also
surfaced and fixed background-blur failure state, NaN formatting and
NaN/-0 finalize clamps. Regression tests: ghostty-config/tests/
zig_parity.rs.
Test Plan:
- cargo test --workspace --no-fail-fast (3456 passed, exit 0)
- just check-macos (both), just check-windows, just check-wasm
