This PR makes Zed's one-second key binding delay visible. Say both ctrl-w and ctrl-w left have bindings. After you press ctrl-w, Zed waits to see whether left follows. The PR shows that wait in the status bar with a countdown. Hovering the indicator shows which bindings can still match. It also adds a setting to hide the indicator. It does not change how Zed resolves key bindings. <img height="100" alt="dyn-db84a840272e2f6250a3f527a59b1efd" src="https://github.com/user-attachments/assets/e42c6a6c-4677-499f-a1d3-835960ebb21a" /> <br/> <img height="100" alt="dyn-8012278d030b41bc8ebfae1540504eff" src="https://github.com/user-attachments/assets/250928d5-f913-40f0-9068-00ccb5cdf59f" /> <br/> <img height="100" alt="file-5e6ffa90944faa294e7870f471b4e65b" src="https://github.com/user-attachments/assets/c250e6eb-a269-4e2c-a5a0-0be9b5006f99" /> Release Notes: - Added a status bar countdown for pending multi-stroke key bindings. --------- Co-authored-by: Kirill Bulatov <kirill@zed.dev>
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.
