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
# Objective
- Fixes#59643.
## Problems
- Initial and minimum width was not migrated for all pickers.
- Some pickers had their width still determined by their wrapper.
- Some pickers where not modals but did not have modal false set.
## Solution
- Migrate the pickers we missed.
- Remove the width being set on the div's wrapping the pickers.
- Set modal false on the missed pickers.

Overhauls Zed's pickers to make them resizable and give them a preview.
Closes#8279
### Background
The most requested Zed feature has the last year has been a [Telescope
like search box](https://github.com/zed-industries/zed/issues/8279)
[discussion](https://github.com/zed-industries/zed/discussions/22581).
To understand why this is so popular we need to understand search can
serve thee goals:
- Navigation: fuzzy search is faster & easier then clicking in a file
tree
- Exploration: example, find a function by a word in its doc comment
- Collecting: example, getting a list of functions to change
The project search which shows results in a multibuffer is the perfect
way to operate on a list of items. Navigation and Exploration need a lot
of context around each result and offer fast navigation between them.
For both of these live searching is also critical.
The `telescope UI` is a picker with a preview to the right or below.
It's offered in various editors and IDE's most famously Neovim (through
the Telescope plugin), IntelliJ (natively), Helix (natively) and of
course VScode (plugins) and it's _many_ forks.
While having a UI like that for text search (our project search) is most
requested the UX pattern is applied widely, from `find_all_references`
to `bookmarks`. It enhances most pickers. Note that we have over 50
different picker modals!
The community has tried to build something like this for Zed:
- https://github.com/zed-industries/zed/pull/44530
- https://github.com/zed-industries/zed/pull/45307
- https://github.com/zed-industries/zed/pull/46478
- https://github.com/zed-industries/zed/pull/43790
These all became huge PR's that we could not merge for various reasons.
This is a really hard feature to integrate in Zed!
This PR got started as https://github.com/zed-industries/zed/pull/46478
and supercedes that.
### Design
- Extend pickers to support an optional preview with minimal changes to
the pickers themselves.
- Make pickers resizable.
- Complement the existing search do not replace it by having both UI's
share the underlying search and allow freely switching between them.
- Allow extending the preview to things other then files.
- Maintain a clean design on all the pickers.
### Heigh level Implementation overview
- Adds an `Option<Preview>` to `Picker`
- Gives `PickerDelegate` a method to communicate a preview to the Picker
- Overhaul the way pickers are drawn to allow for resizing them.
Implemented on the `Shape` and `SizeBouds` structs.
- Adds a high level way to draw the `footer` and `editor` so we do not
need to change much to the pickers.
- Adds a new text finder Picker
- Adds a way to take a running search from project search and hand it to
the text finder Picker and the other way round
- Give the file finder a preview
### Next steps
A more detailed list and how to help out will be added to the tracking
issue for [Pickes with
previews](https://github.com/zed-industries/zed/issues/56037)
- Add more previews to more pickers!
- Enable selectioning multiple items in pickers and performing actions
on those
- Open selected items in a multibuffer
- Add a way to restore the last picker
- Make popovers (picker attached to some menu) resizable as well

Previously, if you wanted to have a button that contains icons on both
edges, you'd need to use a `ButtonLike` component, which takes any
children. Meanwhile, the `Button` would only take one icon, where you
could control its position through the `IconPosition` enum. This has
always felt unnecessarily limiting. So, this PR removes this limitation
by adding two new methods to the button: `start_icon` and `end_icon`.
In the meantime, I have also been bothered by the unnecessary
indirection in the `IconButton` due to the existence of the `ButtonIcon`
component. So I figured I could also completely eliminate that by adding
some of its methods directly to the `IconButton` and in the Button, just
using a regular `Icon` component.
---
## Before
```rust
Button::new("id", "Label")
.icon(IconName::Plus)
.icon_position(IconPosition::Start)
.icon_size(IconSize::Small)
.icon_color(Color::Muted)
```
## After
```rust
Button::new("id", "Label")
.start_icon(Icon::new(IconName::Check))
.end_icon(Icon::new(IconName::ChevronDown).size(IconSize::XSmall))
```
This should have no visual impact to the UI.

On Windows, the WSL VM always boots up when Zed is opened, because we
eagerly discover which jupyter kernels are installed inside WSL on
startup. This is not desirable if the REPL feature is not being used.
Defer this work to the point where we actually need to know what kernels
are installed.
Release Notes:
- N/A
Split WslRemote out of the remote_kernels bucket in the kernel picker,
giving it its own "WSL Kernels" section. Use the distro name and
kernelspec display name for WSL entries instead of the generic "WSL"
string.
In python_env_kernel_specifications, detect WSL projects via
RemoteConnectionOptions and return WslRemote instead of SshRemote. Stop
marking WSL worktrees as remote so global kernel specs load.
Fix ark kernel stdout pollution by building the wsl.exe bash command
with a quoted cd and inline env assignment, so exec replaces the shell
and doesn't echo input back.
Closes#50459
Before you mark this PR as ready for review, make sure that you have:
- [x] Added a solid test coverage and/or screenshots from doing manual
testing
- [x] Done a self-review taking into account security and performance
aspects
- [x] Aligned any UI changes with the [UI
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)

Closes#15196, #46918
- fix: notebook_ui, use buffer so that notebooks open in remote/WSL
settings.
- fix: add musl in nix for cross-compilation, without this remote server
doesn't build inside NixOS
Release Notes:
- Implement WSL and SSH remote kernels (crates/repl/src/kernels/*) and
wire up spawn/kill kernel proto messages and client requests.
This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.

There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge

- Adds the Switch component
- Updates `Selected`, `Selectable` -> `ToggleState`, `Toggleable`
- Adds `checkbox` and `switch` functions to align better with other
elements in our layout system.
We decided not to merge Switch and Checkbox. However, in a followup I'll
introduce a Toggle or AnyToggle enum so we can update
`CheckboxWithLabel` -> `ToggleWithLabel` as this component will work
exactly the same with either a Checkbox or a Switch.

This PR introduces a unified interface for both native and remote
kernels through the `RunningKernel` trait. When either the native kernel
or the remote kernels are started, they return a `Box<dyn
RunningKernel>` to make it easier to work with the session. As a bonus
of this refactor, I've dropped some of the mpsc channels to instead opt
for passing messages directly to `session.route(message)`. There was a
lot of simplification of `Session` by moving responsibilities to
`NativeRunningKernel`.
No release notes yet until this is finalized.
* [x] Detect remote kernelspecs from configured remote servers
* [x] Launch kernel on demand
For now, this allows you to set env vars `JUPYTER_SERVER` and
`JUPYTER_TOKEN` to access a remote server. `JUPYTER_SERVER` should be a
base path like `http://localhost:8888` or
`https://notebooks.gesis.org/binder/jupyter/user/rubydata-binder-w6igpy4l/`
Release Notes:
- N/A
Closes#18341
* [x] Remove "Change Kernel" Doc link from REPL menu
* [x] Remove chevron
* [x] Set a higher min width
* [x] Include the language along with the kernel name
Future PRs will address
* Add support for Python envs (#18291, #16757, #15563)
* Add support for Remote kernels
* Project settings support (#16898)
Release Notes:
- Added kernel picker for repl
