Closes #27385 Builds on #27604 so that `vim::OtherEnd` works in visual block mode. This is accomplished by reversing the order of active selections in the buffer when the user hit `o`, so that the cursor moves diagonally across the selection. The current behavior is preserved for `shift-o`, which is how the cursors behave in vim. We'll close #27604 since this encapsulates that change, but if you'd prefer to take only the visual block motion component, we'll keep the branch for #27604 open. Test case: growing a box down and to the right, other ending, followed by growing and shrinking the box: https://github.com/user-attachments/assets/1df544e1-efce-4354-b354-bbfec007a7df Test case: growing a box up and to the left, other ending, followed by growing and shrinking the box: https://github.com/user-attachments/assets/2f6d7729-c63a-4486-960b-23474c2e507a Release Notes: - Improved visual block mode when cursor is at beginning of selection - Improved visual block mode so that `o` and `shift-o` reach parity with vim --------- Co-authored-by: KyleBarton <kjbarton4@gmail.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:
|
|
|
|
```rust
|
|
#[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:
|
|
|
|
```sh
|
|
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.
