Adds a text property for controlling left, center, or right text
alignment.
#8792 should stay open since this doesn't add support for `justify`
(which would require a much bigger change since this can just alter the
origin of each line, but justify requires changing spacing, whereas
justify requires changes to each platform's shaping code).

This PR updates function signatures, docstrings, and gpui's other
documentation to reflect it's new state following the merge of `Model`
and `View` into `Entity` as well as the removal of `WindowContext`.
Release Notes:

This PR adds two helpers methods to the `TextSystem`:
- `em_width`
- `em_advance`
These methods return the width and advance width for an `em`,
respectively.
We were using these definitions in a number of different spots, and by
unifying them we better canonicalize that an `em` is based on the `m`
character.

GPUI applications can set the window class by the `app_id` window
option. However, GPUI will map the window first and then change the
window class after the window is displayed. This doesn't work on some
X11 window managers. FVWM, for example, does not track window class
after a window is mapped. Because in practice, a window shouldn't change
its application group on the fly.
This PR fixed this by adding a `map_window()` function `PlatformWindow`.
On X11, it will `set_app_id()` first and then map the window.

Previously, editor elements had to listen for mouse_up events to
determine when a click had completed. This meant that they only had
access to modifier keys that were pressed during the mouse_up event.
This led to some incorrect user experiences, such as executing a
ctrl+click if the user pressed ctrl after pressing the mouse button, but
before releasing it.
This change adds a click event handler to EditorElement, and adds a
modifier() method to the ClickEvent, which only includes the modifier
keys that were pressed during both mouse down and mouse up. The code for
handling link clicks has been moved into the click event handler, so
that it's only triggered when the non-multi-cursor modifier was held for
both the mouse down and mouse up events.
Closes#12752, #16074, #17892 (the latter two seem to be duplicates of
the former!)
Release Notes:
- Fixed a bug where pressing ctrl/cmd (or other modifiers) after mouse
down but before mouse up still triggered ctrl/cmd+click behavior (e.g.
"go to definition")
Closes#14170
To fix this, Zed needs to handle swipe events on its NSView. Logitech
mice don't send the usual Mouse4 and Mouse5 buttons but emulate swipe
gestures according to these websites:
- https://superuser.com/a/1216049
- https://sensible-side-buttons.archagon.net/
Of course, the user can map these buttons to something else in the
device's driver. Most IDEs (VSCode, IntelliJ) handle that correctly by
default so it would be good to follow that pattern.
Since it's my first contribution here, please let me know if I need to
enhance this PR to make it good enough for the main branch.
Release Notes:
- Fixed mouse navigation buttons on some devices (Logitech, Mac OS)
This PR prevents situations like
https://github.com/zed-industries/zed/pull/23850, which caused our linux
nightly build to fail to open at all.
This PR also sorts the GPUI build and dev dependencies out from the sea
of platform specific dependencies.

- [x] Fix extra lines between Path vertices wait #22808 to merge.
Ref https://github.com/kvark/blade/pull/213
Ask @kvark to review.
I am not sure if there is anything I missed. I modified it according to
the
[particle](https://github.com/kvark/blade/tree/main/examples/particle)
example of Blade project. But the difference is that after the first
MSAA render, I did not do it a second time, I tested it and found it was
not necessary.
TODO:
- [x] BackgroundOrientation
- [x] PatternDash
- [x] `pattern_horizontal_dash` & `pattern_vertical_dash`
- [x] Metal dash shader
- [x] Blade dash shader
- [x] Update ui::Divider to use new pattern
---
This PR introduces proper dashed dividers using the new `PatternDash`
background shader.

Before this we were using 128 elements to create a dashed divider, which
is both expensive, and would not scale beyond a certain size. This
allows us to simplify the divider element as well.
Changes:
- Adds `BackgroundOrientation` to `gpui::color::Background` to allow
specifying a direction for a pattern
- Adds the PatternDash pattern variant
- Updates `ui::Divider`'s dashed variants to be more efficient
Misc:
- Documents the `ui::Divider` component
- Treat `.metal` files as `C` in the Zed project until we get some metal
syntax highlighting.
Release Notes:
- N/A
TODO:
- [x] Add BackgroundTag::PatternSlash
- [x] Support metal slash pattern fills
- [x] Support blade slash pattern fills
---
Adds support for a new background type in gpui, `pattern_slash`.
Usage:
```rust
div().size(px(56.0)).bg(pattern_slash(gpui::red()))
```
This will create a 56px square with a red slash pattern fill.
You can run the pattern example with `cargo run -p gpui --example
pattern`:

---
After talking with @as-cii at length about how we want to support
patterns in gpui, we decided for now we'll simply add a new
BackgroundTag specific to this pattern.
It isn't the best long term plan however – we'll likely want to
introduce the concept of a `Fill` at some point so we can have
`Fill::Solid`, `Fill::Gradient(LinearGradient)`, etc in the future.
The pattern is designed to seamlessly tile vertically for elements of
the same height. For example, for use in editor line backgrounds:

I recently noticed that on my Windows 11 machine, Zed no longer receive
the `WM_DWMCOLORIZATIONCOLORCHANGED` message when the system theme
changes. This functionality was present in the past. While this change
might be unexpected, it's understandable given Microsoft's history of
system updates.
This pull request proposes an alternative approach using the
`WM_SETTINGCHANGE` message to handle theme changes.
Release Notes:
- N/A
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
Fix a bug where a GPUI macro still used `ModelContext`
Rename `AsyncAppContext` -> `AsyncApp`
Rename update_model, read_model, insert_model, and reserve_model to
update_entity, read_entity, insert_entity, and reserve_entity
Release Notes:
- N/A
Closes#23621
Change was in #23378. Also adds a comment to clarify why this is
inconsistent with all other uses of `bindings_for_action`.
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
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures

#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.

Closes#22653 again
In PR #23283, I thought that every `runnable` dispatched to the main
thread would correspond to an `EVENT_DISPATCHED` message in the message
queue. However, after testing, some `runnable`s occasionally weren’t
executed.
This PR updated the code as follows:
```rust
if let Ok(runnable) = self.main_receiver.try_recv() { <-- before
for runnable in self.main_receiver.drain() { <-- after
runnable.run();
}
```
This ensures that runnables are handled more proactively on the main
thread, now we handle `runnable`s with a much higher priority.
A big thanks to @MolotovCherry and @ArthurBrussee for their testing
efforts!
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
Closes#23015
Release Notes:
- Improved which keybindings are selected for display. Now later entries
within `bindings` will take precedence. The default keymaps have been
updated accordingly.
Adds support for Cut, Copy, Paste, Undo, Redo, New, Open, Save, and Find
keys to the default keymap. These keys can be found on old keyboards,
but also custom layouts like
[Extend](https://dreymar.colemak.org/layers-extend.html).
Release Notes:
- Added support for the Cut, Copy, Paste, Undo, Redo, New, Open, Save,
and Find keys to the default keymap.
This PR renames the constants and functions previously introduced in
PR#23283. Since the changes are within the GPUI crate, I renamed these
from `**_ZED_**` to `**_GPUI_**`.
Release Notes:
- N/A
* Collects and reports all parse errors
* Shares parsed `KeyBindingContextPredicate` among the actions.
* Updates gpui keybinding and action parsing to return structured
errors.
* Renames "block" to "section" to match the docs, as types like
`KeymapSection` are shown in `json-language-server` hovers.
* Removes wrapping of `context` and `use_key_equivalents` fields so that
`json-language-server` auto-inserts `""` and `false` instead of `null`.
* Updates `add_to_cx` to take `&self`, so that the user keymap doesn't
get unnecessarily cloned.
In retrospect I wish I'd just switched to using TreeSitter to do the
parsing and provide proper diagnostics. This is tracked in #23333
Release Notes:
- Improved handling of errors within the user keymap file. Parse errors
within context, keystrokes, or actions no longer prevent loading the key
bindings that do parse.
It's easy to overshoot the bottom of the tooltip when cursoring to a
button, such as opening the commit from a blame tooltip. Before this
change the tooltip would immediately disappear, and now it sticks around
for a bit.
Also:
* Shares the implementation with `elements/text.rs`. This will
particularly be handy when it makes use of hoverable tooltips.
* Improves the fix to #21657.
- Now the element will no longer think it has an active tooltip that it
registers with the window.
- It will instead display the next available tooltip, whereas I believe
before the next available tooltip would be suppressed.
* Fixes bug where `cx.refresh()` wasn't called when text tooltip is
hidden due to a mouse down event.
* Ports over fix in https://github.com/zed-industries/zed/pull/14832 to
`elements/text.rs`
Release Notes:
- The tooltip for inline git blame now waits a bit before disappearing
when the mouse leaves it.
Closes#22653
After some investigation, I found this bug is due to that sometimes
`foreground_task` is not dispatched to the main thread unless there is
user input. The current Windows implementation works as follows: when
the `WindowsDispatcher` receives a `foreground_task`, it adds the task
to a queue and uses `SetEvent(dispatch_event)` to notify the main
thread.
The main thread then listens for notifications using
`MsgWaitForMultipleObjects(&[dispatch_event])`.
Essentially, this is a synchronous method, but it is not robust. For
example, if 100 `foreground_task`s are sent, `dispatch_event` should
theoretically be triggered 100 times, and
`MsgWaitForMultipleObjects(&[dispatch_event])` should receive 100
notifications, causing the main thread to execute all 100 tasks.
However, in practice, some `foreground_task`s may not get a chance to
execute due to certain reasons.
As shown in the attached video, when I don't move the mouse, there are
about 20-30 `foreground_task`s waiting in the queue to be executed. When
I move the mouse, `run_foreground_tasks()` is called, which processes
the tasks in the queue.
https://github.com/user-attachments/assets/83cd09ca-4b17-4a1f-9a2a-5d1569b23483
To address this, this PR adopts an approach similar to `winit`. In
`winit`, an invisible window is created for message passing. In this PR,
we use `PostThreadMessage` to directly send messages to the main thread.
With this implementation, when 100 `foreground_task`s are sent, the
`WindowsDispatcher` uses `PostThreadMessageW(thread_id,
RUNNABLE_DISPATCHED)` to notify the main thread. This approach enqueues
100 `RUNNABLE_DISPATCHED` messages in the main thread's message queue,
ensuring that each `foreground_task` is executed as expected. The main
thread continuously processes these messages, guaranteeing that all 100
tasks are executed.
Release Notes:
- N/A
Context pills are now focusable and intractable via the keyboard.
- <kbd>←</kbd> and <kbd>→</kbd> move the focus to the previous or next
item (wrapping if necessary)
- <kbd>↓</kbd> and <kbd>↑</kbd> move the focus vertically
- If the cursor is in the first/last row of the assistant/inline editor,
they will move the focus to the strip
- Inside the strip, they will move the focus to the pill horizontally
overlapping the most
- If already in the first/last row of the strip, they will move to the
first/last pill (like in editors)
- If the first/last pill is focused, they will move the focus back to
the editor
- <kbd>⌫</kbd> removes the focused pill (unless it's the suggested one)
- <kbd>⏎</kbd> accepts the suggested pill if focused

rust-analyzer does not support derive_macro expansion in attributes -
https://github.com/rust-lang/rust-analyzer/issues/8092. This could be
worked around via a proc_macro, but I think it'd be best to just require
docs for every action.
Release Notes:
- N/A
Also:
* Adds `impl_internal_actions!` for deriving the `Action` trait without
registering.
* Removes some deserializers that immediately fail in favor of
`#[serde(skip)]` on fields where they were used. This also omits them
from the schema.
Release Notes:
- Keymap settings file now has more JSON schema information to inform
`json-language-server` completions and info, particularly for actions
that take input.
