The recent "pickers with previews" overhaul left the picker
sizing/presentation API spread across several overlapping knobs that
every call site had to set correctly — and many didn't, causing pickers
across the app to render at the wrong width, lose their container, or
stop dismissing. This PR consolidates that surface into a small,
hard-to-misuse API and makes correct sizing the default.
Net effect: a plain `Picker::uniform_list(delegate, …)` now renders
correctly out of the box (standard width, standard max-height, shrinks
to fit, dismisses properly), and the ~35 call sites only specify what
genuinely differs.
## API changes
**Presentation** — three overlapping booleans (`is_modal`, `is_popover`,
`is_resizable`) collapsed into one enum, with resizability living inside
the only variant where it's meaningful:
```rust
enum Presentation {
Modal { resizable: bool }, // own chrome, dismisses on blur, optionally resizable
Popover, // own chrome, dismisses on blur, never resizable
Embedded, // host container owns chrome + dismissal
}
```
- `modal(bool)` is **removed** in favor of explicit, self-documenting
builders:
- *(default)* → `Modal` (resizable iff it has a preview)
- `.popover()` → `Popover` (menu-attached surfaces)
- `.embedded()` → `Embedded` (pickers nested in a larger modal/view)
- Dynamic callers use `.when(cond, Picker::embedded)` (added `impl
FluentBuilder for Picker`).
**Sizing** — preview-vs-not now drives everything; the manual padding
knob is gone:
| Before | After |
|---|---|
| `vertical_padding` field + `no_vertical_padding()` | removed — derived
from whether a preview is visible |
| `height(...)` (ambiguous: fixed vs max) | `max_height(...)` (plain
pickers shrink-to-fit, capped here) |
| `minimum_results_width(...)` | removed — a plain picker's min width
tracks its opening width; preview pickers use standard internal pane
mins |
| default size = 60% viewport | default = `DEFAULT_MODAL_WIDTH` (34rem)
× `DEFAULT_MODAL_MAX_HEIGHT` (24rem, max) |
| resize handles gated on `is_modal` | gated on `is_resizable` (new
`resizable(bool)` builder; auto-`true` for preview pickers) |
Call sites now only override the exceptions: narrow popover selectors
(`initial_width`), the taller outline view (`max_height`), and preview
pickers (constructed via `*_with_preview`).
## Behavior fixes
- **Wrong widths everywhere**: pickers were falling back to
60%-of-viewport because the original migration set
`minimum_results_width` but never `initial_width`. Fixed at the source
via the new defaults.
- **Popovers had no container and wouldn't dismiss**: `is_modal=false`
was suppressing both the elevated background *and* blur-dismiss. Split
out so popovers keep their chrome and dismiss on click-away/escape. This
fixed the agent-panel model/profile selectors, sidebar recent projects,
and the settings theme/font/icon/ollama pickers (which were incorrectly
using `modal(false)`).
- **Sidebar recent projects stretched to full height**: was missing the
shrink-to-fit behavior; now capped and content-sized like other
popovers.
- **Preview crash**: removed an over-strict `debug_assert!` that
panicked when previewing an empty file (`message == None && editor
empty` is valid).
- **Preview-aware default size**: pickers open at standard width with
the preview hidden, and expand to the larger "telescope" size when a
preview is shown. Fixes the text finder rendering super-wide by default,
and makes the file finder expand (rather than cram its results) when you
toggle the preview.

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.
