- 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)

//! Link the final binary with lazy symbol binding.

//!
|
|
//! Rust links executables with `-z now` (eager binding) by default. The GTK
|
|
//! apprt compiles in code for newer GTK/libadwaita API (e.g. the GTK 4.16 CSS
|
|
//! diagnostics) that is only ever called after a runtime `at_least` check,
|
|
//! exactly like the Zig build, which links GTK dynamically with lazy binding.
|
|
//! With eager binding the dynamic loader would refuse to start the program on
|
|
//! an older library that merely lacks such a symbol; with lazy binding the
|
|
//! symbol is only resolved if the guarded code actually runs.
