Single-commit orphan branch: full zed-industries/zed @ 8c74db0 source tree with a 3-file patch applied (no upstream history). Patch (crates/gpui_linux/src/linux/wayland/): - serial.rs: add SerialKind::KeyboardEnter - client.rs: store wl_keyboard.enter serial; add latest_serial_of() - window.rs: activate() uses keyboard-enter serial (Mutter focus gate) Mutter honors window activation only when the token carries the keyboard- focus serial from wl_keyboard.enter; GPUI used a stale mouse-press serial. See docs/tray-window-focus-wayland.md in logiguard. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

This contains the code for Zed's Vim emulation mode.
Vim mode in Zed is supposed to primarily "do what you expect": it mostly tries to copy vim exactly, but will use Zed-specific functionality when available to make things smoother. This means Zed will never be 100% vim compatible, but should be 100% vim familiar!
The backlog is maintained in the #vim channel notes.
Testing against Neovim
If you are making a change to make Zed's behavior more closely match vim/nvim, you can create a test using the NeovimBackedTestContext.
For example, the following test checks that Zed and Neovim have the same behavior when running * in visual mode:
#[gpui::test]
async fn test_visual_star_hash(cx: &mut gpui::TestAppContext) {
let mut cx = NeovimBackedTestContext::new(cx).await;
cx.set_shared_state("ˇa.c. abcd a.c. abcd").await;
cx.simulate_shared_keystrokes(["v", "3", "l", "*"]).await;
cx.assert_shared_state("a.c. abcd ˇa.c. abcd").await;
}
To keep CI runs fast, by default the neovim tests use a cached JSON file that records what neovim did (see crates/vim/test_data), but while developing this test you'll need to run it with the neovim flag enabled:
cargo test -p vim --features neovim test_visual_star_hash
This will run your keystrokes against a headless neovim and cache the results in the test_data directory. Note that neovim must be installed and reachable on your $PATH in order to run the feature.
Testing zed-only behavior
Zed does more than vim/neovim in their default modes. The VimTestContext can be used instead. This lets you test integration with the language server and other parts of zed's UI that don't have a NeoVim equivalent.
