We've been considering removing workspace-hack for a couple reasons: - Lukas ran into a situation where its build script seemed to be causing spurious rebuilds. This seems more likely to be a cargo bug than an issue with workspace-hack itself (given that it has an empty build script), but we don't necessarily want to take the time to hunt that down right now. - Marshall mentioned hakari interacts poorly with automated crate updates (in our case provided by rennovate) because you'd need to have `cargo hakari generate && cargo hakari manage-deps` after their changes and we prefer to not have actions that make commits. Currently removing workspace-hack causes our workspace to grow from ~1700 to ~2000 crates being built (depending on platform), which is mainly a problem when you're building the whole workspace or running tests across the the normal and remote binaries (which is where feature-unification nets us the most sharing). It doesn't impact incremental times noticeably when you're just iterating on `-p zed`, and we'll hopefully get these savings back in the future when rust-lang/cargo#14774 (which re-implements the functionality of hakari) is finished. Release Notes: - N/A
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.
