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.

# Objective
- Fixes#59643.
## Problems
- Initial and minimum width was not migrated for all pickers.
- Some pickers had their width still determined by their wrapper.

## 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

## Context
### Background
Currently, a multibuffer consists of an arbitrary list of
anchor-delimited excerpts from individual buffers. Excerpt ranges for a
fixed buffer are permitted to overlap, and can appear in any order in
the multibuffer, possibly separated by excerpts from other buffers.
However, in practice all code that constructs multibuffers does so using
the APIs defined in the `path_key` submodule of the `multi_buffer` crate
(`set_excerpts_for_path` etc.) If you only use these APIs, the resulting
multibuffer will maintain the following invariants:
- All excerpts for the same buffer appear contiguously in the
multibuffer
- Excerpts for the same buffer cannot overlap
- Excerpts for the same buffer appear in order
- The placement of the excerpts for a specific buffer in the multibuffer
are determined by the `PathKey` passed to `set_excerpts_for_path`. There
is exactly one `PathKey` per buffer in the multibuffer
### Purpose of this PR
This PR changes the multibuffer so that the invariants maintained by the
`path_key` APIs *always* hold. It's no longer possible to construct a
multibuffer with overlapping excerpts, etc. The APIs that permitted
this, like `insert_excerpts_with_ids_after`, have been removed in favor
of the `path_key` suite.
The main upshot of this is that given a `text::Anchor` and a
multibuffer, it's possible to efficiently figure out the unique excerpt
that includes that anchor, if any:
```
impl MultiBufferSnapshot {
fn buffer_anchor_to_anchor(&self, anchor: text::Anchor) -> Option<multi_buffer::Anchor>;
}
```
And in the other direction, given a `multi_buffer::Anchor`, we can look
at its `text::Anchor` to locate the excerpt that contains it. That means
we don't need an `ExcerptId` to create or resolve
`multi_buffer::Anchor`, and in fact we can delete `ExcerptId` entirely,
so that excerpts no longer have any identity outside their
`Range<text::Anchor>`.
There are a large number of changes to `editor` and other downstream
crates as a result of removing `ExcerptId` and multibuffer APIs that
assumed it.
### Other changes
There are some other improvements that are not immediate consequences of
that big change, but helped make it smoother. Notably:
- The `buffer_id` field of `text::Anchor` is no longer optional.
`text::Anchor::{MIN, MAX}` have been removed in favor of
`min_for_buffer`, etc.
- `multi_buffer::Anchor` is now a three-variant enum (inlined slightly):
```
enum Anchor {
Min,
Excerpt {
text_anchor: text::Anchor,
path_key_index: PathKeyIndex,
diff_base_anchor: Option<text::Anchor>,
},
Max,
}
```
That means it's no longer possible to unconditionally access the
`text_anchor` field, which is good because most of the places that were
doing that were buggy for min/max! Instead, we have a new API that
correctly resolves min/max to the start of the first excerpt or the end
of the last excerpt:
```
impl MultiBufferSnapshot {
fn anchor_to_buffer_anchor(&self, anchor: multi_buffer::Anchor) -> Option<text::Anchor>;
}
```
- `MultiBufferExcerpt` has been removed in favor of a new
`map_excerpt_ranges` API directly on `MultiBufferSnapshot`.

Closes#39172
This refactors when we resolve UI keybindings in an effort to reduce
flickering whilst painting these: Previously, we would always resolve
these upon creating the binding. This could lead to cases where the
corresponding context was not yet available and no binding could be
resolved, even if the binding was then available on the next presented
frame. Following that, on the next rerender of whatever requested this
keybinding, the keybind for that context would then be found, we would
render that and then also win a layout shift in that process, as we went
from nothing rendered to something rendered between these frames.
With these changes, this now happens less often, because we only look
for the keybinding once the context can actually be resolved in the
window.

Also reduced cloning in the keymap editor in this process, since that
requiered changing due to this anyway.
Release Notes:
- Fixed some cases where keybinds would appear with a slight delay,
causing a flicker in the process
This is a follow-up PR to
https://github.com/zed-industries/zed/pull/39609, and attempts to
address hidden status bar items still contributing to the layout and
creating extra spacing.

- 203cbd634bfb1489b8afa4952d9594615a956b77 Adds a `.none()` method to
the `gpui::Styled` helper trait, so that status items can set their
display type to none inside their `render` method.
- 249f06e3de63b0ab32814f20e7105d8e2b642f02 Applies `.none()` to all the
status items.
- ~~499f564906c88336608c81615b11ebc9ab43d832~~ At first I was adding an
`is_visible` method to the `StatusBarView` trait, which would be used to
skip status bar items which would just render an empty div anyway, but I
felt duplicating the conditions for hiding the buttons between the
status items `is_visible` and `render` methods could be an attraction
for bugs, so I tried to find another approach. This commit contains
those changes, reverted immediately (if the `is_visible` approach is
preferred I can bring it back!)
- f37cb75f0519ceea1f3e1cc4f97087a5cb34b0fd (bonus!) Adds a condition to
the vim mode indicator to avoid a leading space when there are no
pending keys.
Release Notes:
- N/A
Release Notes:
- Added settings status_bar.show_active_language_button to show/hide the
language button in the status bar.
The motivation for this is visual, I have had zero issues with its
functionality.
The language switcher can still be accessed by the command palette,
menu, or a keyboard shortcut.
------
This is my first Zed and first Rust PR, so criticism is very welcome.
I know there has been discussion around how the status bar settings are
structured and named, and I am happy to change it to whatever is best. I
was also not sure what order to put it in in the settings default.json.
Feedback welcome.
Here is a picture of it in action:

This PR changes the signature of `language_names` from
```rust
pub fn language_names(&self) -> Vec<String>
// Into
pub fn language_names(&self) -> Vec<LanguageName>
```
The function previously eagerly converted `LanguageName`'s to
`String`'s, which requires the reallocation of all of the elements. The
functions get called in many places in the code base, but only one of
which actually requires the conversion to a `String`. In one case it
would do a `SharedString` -> `String` -> `SharedString` conversion,
which is now totally bypassed.

Closes #ISSUE
Adds a new `documentation` method to actions, that is extracted from doc
comments when using the `actions!` or derive macros.
Additionally, this PR adds doc comments to as many action definitions in

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

This PR fixes a rare case where icons could be missing in the language
selector.
Currently, whilst looking up an icon, all file suffixes starting with a
dot are filtered out. While this works fine for some languages, there
are some languages having only file suffixes starting with a dot, e.g.
the "Git Attributes" language provided from the "Git Firefly" extension.
This results in no icon being displayed in the list, as shown in the
screenshots below.
To solve this, we can just simply remove the check for this special case
as well as the construction of an artificial file name in the code, as
both are not needed. A simple path just consisting of the extension is
sufficient, as we currently do not differentiate between file names and
file suffixes during an icon lookup. see the relevant code below:
https://github.com/zed-industries/zed/blob/fcc3efa26d99836252729f55fe3125e4e4dc4fe7/crates/file_icons/src/file_icons.rs#L23-L52
As the first lookup is directly done using the entire file name and then
checked against all suffixes, we actually do not have to construct an
artificial file name at all. Should that produce no match, we check for
a hidden file right after, so we do not have to filter hidden file names
out.
With this fix, nothing changes for "normal" file suffixes, for some
cases where languges provide entire file names as a path suffix, the
matching might improve, and for languages with only hidden associated
file names, the initially described issue is resolved.
I do believe the behavior of matching icons to languages could be
improved in general. Fowever, I do think this is beyond the scope of
this change.

Aditionally, in 4395f78fb2c49f74c4bfa6b4146aee8b55435838 I refactored
the code which acquires the label and icon for a match, since I found it
a bit hard to read initially. The majority of this diff comes from this
change. Should that not be wanted, I can revert that change.
Release Notes:
- Fixed a rare case where languages had no associated icon in the
language selector.
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!

- 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.
Release Notes:
- N/A
Due to filtering after enumeration, initial candidate ids are assigned
incorrectly. This later causes the wrong item to be picked up when
accessed via index in the vector.
Closes#20476
Release Notes:
- Fixed a bug in toolchain selector that caused it to not pick up venvs
for tabs before user interacted with them.
- Fixed a bug in language selector that caused it to pick up Markdown as
the language for a buffer up until the tab was interacted with.
This PR renames the `h_stack` and `v_stack` to `h_flex` and `v_flex`,
respectively.
We were previously using `h_stack` and `v_stack` to match SwiftUI, but
`h_flex` and `v_flex` fit better with the web/flexbox terminology that
the rest of GPUI uses.
Additionally, we were already calling the utility functions used to
implement `h_stack` and `v_stack` by the new names.
