When trying to split and clone a non clone-able workspace item we now
attempt split and move instead of doing nothing. Additionally we disable
the split menu buttons if we can't split the active item at all.
Release Notes:
- Improved handling of unsplittable panes
Split out from https://github.com/zed-industries/zed/pull/40774 to
reduce the size of the reland of that PR (once I figure out the cause of
the issue)

We were spawning the process on the foreground thread before which can
block an arbitrary amount of time. Likewise we no longer block
deserialization on the terminal loading.
Release Notes:
- Improved startup time on systems with slow process spawning
capabilities

This PR re-applies the initial
[PR](https://github.com/zed-industries/zed/pull/30840). As it was closed
because it was hard to land, because of the many conflicts. This PR
re-applies the changes for it.
In several cases we were creating multiple display_map
snapshots within the same root-level function call.
Creating a display_map snapshot is quite slow, and in some
cases we were creating the snapshot multiple times.

`MultiBuffer::anchor_in_excerpt` currently just wraps the given text
anchor in a multibuffer anchor. This allows one to get a multibuffer
anchor that points outside its excerpt which is basically never what one
wants. This PR now does a bounds check and returns `None` if the given
text anchor is not within the bounds of the excerpt.

This PR adds default scrollbars to the markdown preview and syntax tree
view.
Release Notes:
- Added scrollbars to the markdown preview and syntax tree view.
In an effort to improve the experience while developing extensions and
improving themes, this PR updates the syntax tree views behavior
slightly.
Before, the view would always update to the current active editor whilst
being used. This was quite painful for improving extension scheme files,
as you would always have to change back and forth between editors to
have a view at the relevant syntax tree.
With this PR, the syntax tree view will now stay attached to the editor
it was opened in, similar to preview views. Once the view is shown, the
`UseActiveEditor` will become available in the command palette and
enable the user to update the view to the last focused editor. On file
close, the view will also be updated accordingly.
https://github.com/user-attachments/assets/922075e5-9da0-4c1d-9e1a-51e024bf41ea
A button is also shown whenever switching is possible.
Futhermore, improved the empty state of the view.
Lastly, a drive-by cleanup of the `show_action_types` method so there is
no need to call `iter()` when calling the method.
Release Notes:
- The syntax tree view will now stay attached to the buffer it was
opened in, similar to the Markdown preview. Use the `UseActiveEditor`
action when the view is shown to change it to the last focused editor.
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.
Release Notes:
- N/A

Adds a new `documentation` method to actions, that is extracted from doc

In #32656 I generalized the argument to change selections to allow
controling both the scroll and the nav history (and the completion
trigger).
To avoid conflicting with ongoing debugger cherry-picks I left the
argument as an `impl Into<>`, but I think it's clearer to make callers
specify what they want here.
I converted a lot of `None` arguments to `SelectionEffects::no_scroll()`
to be exactly compatible; but I think many people used none as an "i
don't care" value in which case Default::default() might be more
appropraite

Release Notes:
- Breaking change: The actions used while developing Zed have been
renamed from `debug:` to `dev:` to avoid confusion with the new debugger

I haven't yet added a default binding for the new command. #27797 added `:ls` and
`:buffers` which in my opinion should use the global searchable version
given that that matches the vim semantics of those commands better than
just showing the tabs in the local pane.
There's also a question of what to do when you select a tab from another
pane, should the focus jump to that pane or should that tab move to the
currently focused pane? For now I've implemented the former.
Release Notes:
- Added `tab_switcher::ToggleAll` to search open tabs from all panes and focus the selected one.

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

second line of the hunk
* [x] Failure to expand diff hunk below the cursor.
* [x] Delete the whole file, and expand the diff. Backspace over the

* [x] backspace at the beginning of a deleted hunk deletes too much text
* [x] Indent guides are rendered incorrectly
* [ ] Fix randomized multi buffer tests
Maybe:
* [ ] Buffer search should include deleted text (in vim mode it turns

* [ ] vim: should refuse to switch into insert mode if selection is
fully within a diff.
* [ ] vim `o` command when cursor is on last line of deleted hunk.
* [ ] vim `shift-o` on first line of deleted hunk moves cursor but
doesn't insert line
* [x] `enter` at end of diff hunk inserts a new line but doesn't move
cursor
* [x] (`shift-enter` at start of diff hunk does nothing)
* [ ] Inserting a line just before an expanded hunk collapses it
Release Notes:
- Improved diff rendering, allowing you to navigate with your cursor
inside of deleted text in diff hunks.

Zed does not scroll always, but only if the item is out of sight, this
is preserved for now.
Otherwise, if the item is out of sight, project and outline panels + the
syntax tree view now attempt to scroll it into the middle, if there's
enough elements above and below.
Release Notes:
- Improved revealing items for outline and project panels (now center of the list is preferred)
This is a behavior-preserving change, but lays the groundwork for
expanding selections when the cursor lands inside of a "replace" block.

This PR adds a streamlined way to consistently construct tab content for
items that only have textual content in the tabs.
The `Item` trait now has a new `tab_content_text` method that can be
used to return the textual content for the tab.
The `tab_content` method now has a default implementation that—unless
overridden—will construct a `Label` out of the text. This default
implementation also takes care of setting the label color based on the
active state of the tab, something that previously had to be repeated in
each `tab_content` implementation.
The majority of our tabs are now using `tab_content_text`.
Release Notes:

This PR replaces the `popover_menu` function for constructing
`PopoverMenu`s with a `PopoverMenu::new` associated function.
This brings `PopoverMenu` in line with our other UI components.

Using the file system as a database seems like it's easy, but it's
actually a real pain. I'd like to use LMDB to store the prompts locally
so we have more control. We can always add an export option, but I want
the source of truth to be somewhere other than the file system.
So far, I have a PromptStore which is global to the application and can
be initialized on startup. Then there's a `PromptLibrary` which is
intended to be the root of a new kind of Zed window. I haven't actually
seen pixels yet, but I've sketched out the basics needed to create a new
prompt, save, etc.
Still lots to figure out but the foundations of being backed by a DB and
rendering in an independent window are in place.

This pull request introduces the new
`ElementContext::request_autoscroll(bounds)` and
`ElementContext::take_autoscroll()` methods in GPUI. These new APIs
enable container elements such as `List` to change their scroll position
if one of their children requested an autoscroll. We plan to use this in
the revamped assistant.
As a drive-by, we also:
- Renamed `Element::before_layout` to `Element::request_layout`
- Renamed `Element::after_layout` to `Element::prepaint`
- Introduced a new `List::splice_focusable` method to splice focusable
elements into the list, which enables rendering offscreen elements that
are focused.

This PR implements the preview tabs feature from VSCode.
More details and thanks for the head start of the implementation here
#6782.
Here is what I have observed from using the vscode implementation ([x]
-> already implemented):
- [x] Single click on project file opens tab as preview
- [x] Double click on item in project panel opens tab as permanent
- [x] Double click on the tab makes it permanent
- [x] Navigating away from the tab makes the tab permanent and the new
tab is shown as preview (e.g. GoToReference)
- [x] Existing preview tab is reused when opening a new tab
- [x] Dragging tab to the same/another panel makes the tab permanent
- [x] Opening a tab from the file finder makes the tab permanent
- [x] Editing a preview tab will make the tab permanent
- [x] Using the space key in the project panel opens the tab as preview
- [x] Handle navigation history correctly (restore a preview tab as
preview as well)
- [x] Restore preview tabs after restarting
- [x] Support opening files from file finder in preview mode (vscode:
"Enable Preview From Quick Open")
I need to do some more testing of the vscode implementation, there might
be other behaviors/workflows which im not aware of that open an item as
preview/make them permanent.
Showcase:
https://github.com/zed-industries/zed/assets/53836821/9be16515-c740-4905-bea1-88871112ef86
TODOs
- [x] Provide `enable_preview_tabs` setting
- [x] Write some tests
- [x] How should we handle this in collaboration mode (have not tested
the behavior so far)
- [x] Keyboard driven usage (probably need workspace commands)
- [x] Register `TogglePreviewTab` only when setting enabled?
- [x] Render preview tabs in tab switcher as italic
- [x] Render preview tabs in image viewer as italic
- [x] Should this be enabled by default (it is the default behavior in
VSCode)?
- [x] Docs
Future improvements (out of scope for now):
- Support preview mode for find all references and possibly other
multibuffers (VSCode: "Enable Preview From Code Navigation")
Release Notes:
- Added preview tabs

Fixes https://github.com/zed-industries/zed/issues/9792
This pull request moves the computation of scrollbar markers off the
main thread, to prevent them from grinding the editor to a halt when we
have a lot of them (e.g., when there are lots of search results on a
large file). With these changes we also avoid generating multiple quads
for adjacent markers, thus fixing an issue where we stop drawing other
primitives because we've drawn too many quads in the scrollbar.
Release Notes:
- Improved editor performance when displaying lots of search results,
diagnostics, or symbol highlights in the scrollbar

### Problem
After transitioning Zed to GPUI 2, we started noticing that interacting
with the mouse on many UI elements would lead to a pretty annoying
flicker. The main issue with the old approach was that hover state was
calculated based on the previous frame. That is, when computing whether
a given element was hovered in the current frame, we would use
information about the same element in the previous frame.
However, inspecting the previous frame tells us very little about what
should be hovered in the current frame, as elements in the current frame
may have changed significantly.
### Solution
This pull request's main contribution is the introduction of a new
`after_layout` phase when redrawing the window. The key idea is that
we'll give every element a chance to register a hitbox (see
`ElementContext::insert_hitbox`) before painting anything. Then, during
the `paint` phase, elements can determine whether they're the topmost
and draw their hover state accordingly.
We are also removing the ability to give an arbitrary z-index to
elements. Instead, we will follow the much simpler painter's algorithm.
That is, an element that gets painted after will be drawn on top of an
element that got painted earlier. Elements can still escape their
current "stacking context" by using the new `ElementContext::defer_draw`
method (see `Overlay` for an example). Elements drawn using this method
will still be logically considered as being children of their original
parent (for keybinding, focus and cache invalidation purposes) but their
layout and paint passes will be deferred until the currently-drawn
element is done.
With these changes we also reworked geometry batching within the
`Scene`. The new approach uses an AABB tree to determine geometry
occlusion, which allows the GPU to render non-overlapping geometry in
parallel.
### Performance
Performance is slightly better than on `main` even though this new
approach is more correct and we're maintaining an extra data structure
(the AABB tree).

Release Notes:
- Fixed a bug that was causing popovers to flicker.
