Fix bugs caused by the window context PR, where the window could be on
the stack and is then requested from the App.
This PR also adds derive macros for `AppContext` and `VisualContext` so
that it's easy to define further contexts in API code, such as
`editor::BlockContext`.
Release Notes:
- N/A
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

Closes#12553
* [x] Fix `diff_hunk_before`
* [x] Fix failure to show deleted text when expanding hunk w/ cursor on
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
deleted hunk, panic!
* [x] Go-to-line now counts the diff hunks, but it should not
* [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
out I use `/x` all the time to jump to the next x I can see).
* [ ] 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.

#23460 brought up we are showing the new "tab Accept" marker for single
line suggestions for non-zeta providers. We think this might be valid
for any provider, but we only want to enable it for zeta initially so it
doesn't affect an existing user base.
Release Notes:
- N/A
#23411 introduced an "Accept" callout for single line edits, but the
logic to detect them was incorrect causing it to trigger for multiline
insertions, this PR fixes that.
Release Notes:
- N/A
Considered doing this when previously working on completions menu
layout, as it brings the default selection position next to the cursor
position, and is generally more symmetrical. With #23445 there is now a
more compelling reason, as the "translucent, cropped bottom" display
doesn't make sense when displayed above.
Release Notes:
- N/A
Add `editor:: SwapSelectionEnds ` action which swaps the cursor location from the beginning/end of a given selection.
Renamed from `editor::ExchangeMark` to `editor::SwapSelectionEnds`.
Unbound by default, bound to `ctrl-x ctrl-x` in Emacs keymap.
If a suggested edit is a single character insert or a single line
deletion, we'll show the diff popover to make it stand out more.

This PR fixes two visual issues, that were caused by the fact that we
were always painting the horizontal scrollbar even if there is no
horizontal scrolling possible
Obscuring deleted lines when using the inline assistant:
https://github.com/user-attachments/assets/f8460c3f-403e-40a6-8622-65268ba2d875
Cutting off text even when horizontal scrolling is not possible:
https://github.com/user-attachments/assets/23c909f7-1c23-4693-8edc-40a2f089d4a8
This issue was only present in some themes (e.g. Nord, Catpuccin)
Closes#22716
Release Notes:
- Fixed an issue where horizontal scrollbars of editors would always be
painted (even if there is no horizontal scrolling to be done)
This enables having a dedicated color for the line number hover state.
That's relevant because line numbers can now be clicked to jump to
cursor location in multibuffers.

This PR fixes an issue with jumping from multi_buffer to a file; namely,
the scroll offset of the opened buffer used to match the position within
the multibuffer, but it broke a while back. This is because we were
opening a buffer without providing the data about the origin scroll
offset.
Closes #ISSUE
Release Notes:
- Fixed a bug where the relative position of an excerpt within the
multibuffer was not accounted for while jumping to the buffer, causing
the clicked line to drastically change position on screen.
I added these notifies in #23011, but in practive have found them to be
overly disruptive. It would definitely be good to do something better
than logging here, but having a sticky error notification is worse. I
think it is still good to notify on mutation failures, so left those in
In particular with rust-analyzer, "Go to definition" and "Find
references" frequently fail with "Content modified" quite a while after
sending the request. Since users are probably used to these operations
being finicky it doesn't seem useful to have a prominent display of
errors for them.
fixed a bug where with the "show_whitespaces": "boundary" option, when
there was an "à" followed by a space, a white space was displayed, and
when "à" was at the end of the line, a white space was added

Clicking buffer headers and line numbers would sometimes take you to a
disorienting scroll position. This PR improves that so the destination
line is roughly at the same Y position as it appeared in the
multibuffer.
https://github.com/user-attachments/assets/3ad71537-cf26-4136-948f-c5a96df57178
**Note**: The alignment won't always be perfect because the multibuffer
and target buffer might start at a different absolute Y position
(because of open search, breadcrumbs, etc). I wanted to compensate for
that, but that requires a fundamental change that I'd prefer to make
separately.
Release Notes:
- Fix vertical alignment when jumping from multibuffers
This PR updates the scrollbar diagnostic setting to provide fine-grained
control over which indicators to show, based on severity level. This
allows the user to hide lower-severity diagnostics that can otherwise
clutter the scrollbar (for example, unused or disabled code).
The options are set such that the existing boolean setting has the same
effect: when `true` all diagnostics are shown, and when `false` no
diagnostics are shown.
Closes#22296.
Release Notes:
- Added fine-grained control of scrollbar diagnostic indicators.
Changes:
- [x] Increase expand affordance surface area
- [x] Ensure expand buttons have tooltips with keybindings
- [x] Make line numbers clickable to jump you to location (only in
multibuffers)
- [x] Hide the "Jump To File" element in not-focused excerpts
Before merging it:
- [x] Fix off-by-one header focus styles glitch
Improvements to consider for follow-up PRs:
1. Experiment with increasing the width of the clickable surface area
for line numbers
2. Don't show (or disable) the "expand excerpt" button when at the top
or bottom edge of the file
3. Once you jump to location, centralize the cursor scroll position
Release Notes:
- Improved multibuffer's "expand excerpt" affordance
- Fixed "jump to file/location" and "expand excerpt" keybinding display
- Made clicking on line numbers in multibuffers jump you to cursor
location in file

* Remove unnecessary WindowContext and ViewContext '_ lifetimes
* Removed some cases where WindowContext has a different name than `cx`.
Release Notes:
- N/A
* Now more often displayed to the right. Resizes docs width if more
space than min width is available.
* If constrained in horizontal space and so displayed above/below resize
docs height to fit.
* Makes space for scrollbar and gap.
Layout is imperfect for viewport sizes smaller than the context menu,
left TODOs in the code for handling this. Wanted to get this change out
for feedback first.
Release Notes:
- N/A
This PR ensures that, for fixed-width fonts, the cursor width is the
same on blank lines as on non-blank lines, as well as at the end of a
line. It does so by using the em advance to define the cursor width
instead of the em width in these cases.
Note that this can look... bizarre on non-fixed-width fonts:
<img width="93" alt="Screenshot 2024-12-19 at 21 43 11"
src="https://github.com/user-attachments/assets/a4c9b26c-98ea-4a1d-947b-51f1acd3c2f8"
/>
However, this is arguably reasonably consistent with how (terminal) Vim
handles it:
<img width="45" alt="Screenshot 2024-12-19 at 21 46 42"
src="https://github.com/user-attachments/assets/ec3ff614-7a15-4cc3-8d14-3d15ce62f2b8"
/>
Closes#22260.
Release Notes:
- N/A
If an inline completion isn't shown in a menu, we highlight text in the
editor as deleted.
But if it's shown in the menu, we didn't even show deleted text, which
makes it hard to understand what's going on.
This fixes it.

Release Notes:
- N/A
* Presence of the aside no longer affects position or size of the
context menu.
* Prefers to fit to the right, then on same side of line, then other
side of line, within the following preference order:
- Max possible size within text area.
- Max possible size within window.
- Actual size within window. This is the only case that could cause it
to jump around with less stability.
A further enhancement atop this might be to dynamically resize aside
height to fit.
Release notes are N/A as they are covered by the notes for #22102.
Closes#8523
Release Notes:
* N/A

Closes#4427
Release Notes:
- Added a horizontal scrollbar to the editor panel
- Added `axis` option to `scrollbar` in the Zed configuration, which can
forcefully disable either the horizontal or vertical scrollbar
- Added `horizontal_scroll_margin` equivalent to
`vertical_scroll_margin` in the Zed configuration
Rough Edges:
This feature seems mostly stable from my testing. I've been using a
development build for about a week with no issues. Any feedback would be
appreciated. There are a few things to note as well:
1. Scrolling to the lower right occasionally causes scrollbar clipping
on my end, but it isn't consistent and it isn't major. Some more testing
would definitely be a good idea. [FIXED]
2. Documentation may need to be modified
3. I added an `AxisPair` type to the `editor` crate to manage values
that have a horizontal and vertical variant. I'm not sure if that's the
optimal way to do it, but I didn't see a good alternative. The `Point`
type would technically work, but it may cause confusion.

* Now decides whether the menu is above or below the target position
before rendering it. This causes its position to no longer vary
depending on the length of completions
* When the text area is height constrained (< 12) lines, now chooses the
side which has the most space. Before it would always display above if
height constrained below.
* Misc code cleanups
Release Notes:
- Improved completions menu layout to be more stable and use available
space better.
- Ensuring that the fold button is big enough to avoid clicking on the
header as a whole (and then moving to the actual file)
- Adding tooltips to the fold button
- Refining the container structure so that the tooltip for the folder
button and the header click don't overlap
- Adding keybindings to tooltips

Release Notes:
- N/A
`CodeContextMenu` is always accessed on one thread, so only `Rc`s and
`Rc<RefCell<_>>` are needed. There should be tiny performance benefits
from this. The main benefit of this is that when seeing code accessing a
`RwLock` it would be reasonable to wonder whether it will block. The
only potential downside is the potential for panics due to overlapping
borrows of the RefCells. I think this is an acceptable risk because most
errors of this nature will be local or will be caught by clippy via the
check for holding a RefCell reference over an `await`.
Release Notes:
- N/A
Closes https://github.com/zed-industries/zed/issues/4925https://github.com/user-attachments/assets/e7b87375-893f-41ae-a2d9-d501499e40d1
Allows to fold any buffer inside multi buffers, either by clicking the
chevron icon on the header, or by using
`editor::Fold`/`editor::UnfoldLines`/`editor::ToggleFold`/`editor::FoldAll`
and `editor::UnfoldAll` actions inside the multi buffer (those were noop
there before).
Every fold has a fake line inside it, so it's possible to navigate into
that via the keyboard and unfold it with the corresponding editor
action.
The state is synchronized with the outline panel state: any fold inside
multi buffer folds the corresponding file entry; any file entry fold
inside the outline panel folds the corresponding buffer inside the multi
buffer, any directory fold inside the outline panel folds the
corresponding buffers inside the multi buffer for each nested file entry
in the panel.
Release Notes:
- Added a possibility to fold buffers inside multi buffers
