libghostty-rs

Building

  • Requires Zig 0.16.x on PATH and a Nix dev shell
  • Enter dev shell: nix develop
  • Check: cargo check
  • Test: cargo test -p libghostty-vt-sys
  • Build example: cargo build -p ghostling_rs
  • Run example: cargo run -p ghostling_rs

Code Conventions

  • Rust workspace: libghostty-vt-sys (FFI bindings), libghostty-vt (safe wrappers), ghostling_rs (example)
  • Opaque pointer pattern: NonNull<ffi::GhosttyFoo> + PhantomData<*mut ()> + Drop
  • Sized structs: set size field to std::mem::size_of::<Type>() before FFI calls
  • from_result() maps GhosttyResult to Result<(), Error>
  • Ghostty source is fetched at build time by build.rs (pinned commit). Override with GHOSTTY_SOURCE_DIR env var to use a local checkout.
  • Comment heavily — explain why, not just what
