Draft as a base for continuing the discussion in #8008 : adds a `SplitOperation` enum to support bindings like `["pane::SplitLeft", {"operation": "Clear"}]` To be discussed @MrSubidubi and others: - Naming: Generally not happy with names yet and specifically `Empty` is unclear, e.g., what does this mean for terminal panes? Added placeholder code to split without cloning, but unsure what users would expect in this case. - ~~I removed `SplitAndMoveXyz` actions but I guess we should keep them for backwards compatibility?~~ - May have missed details in the move implementation. Will check the code again for opportunities to refactor more code after we agree on the approach. - ~~Tests should go to `crates/collab/src/tests/integration_tests.rs`?~~ Closes #8008 Release Notes: - Add `pane::Split` mode (`{ClonePane,EmptyPane,MovePane}`) to allow creating an empty buffer. --------- Co-authored-by: Finn Evers <finn.evers@outlook.de> Co-authored-by: MrSubidubi <finn@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.
