Happy New Years! This PR is a second take at
https://github.com/zed-industries/zed/pull/38127 (cc @ConradIrwin)
This PR is significantly less complicated than the last attempt: while
we still keep our data on the `NavigationHistory` object, we no longer
tightly integrate it with the existing back/forward "browser history."
Instead, we keep our own stack of `(origin, target)` pairs (in a struct
to make it easy to extend with e.g., tag names in the future).
The PR is split into two separable commits. Most of the implementation
is in the second commit, which:
- Defines the stack data structure
- Implements `pane::GoToOlderTag` and `pane::GoToNewerTag` in terms of
the stack
- Hooks into `navigate_to_hover_links` to push tag stack entries
This last bit is the most fiddly. The core challenge is that we need to
keep track of the `origin` location and calculate the `target` location
across three codepaths that might involve creating a new editor and/or
splitting the pane. One thing in particular I found difficult was that
an editor's `nav_history` (an `ItemNavHistory`) seems to be populated
asynchronously. Instead of relying on it, I decided in this code to make
my own `ItemNavHistory`. I briefly tried to refactor the code in
question, but it seemed like it would significantly increase the scope
of the change.
I prefer this all-in-one tracking centered around
`navigate_to_hover_links ` to the `start/finish` approach taken in
https://github.com/zed-industries/zed/commit/b69a2ea200561de9de0edf4d0c4428ee887fb918
because I find it easier to convince myself that the right data is being
populated at the right times. Of course, let me know if you think
there's a better solution.
Closes#14206
Release Notes:
- ??? I don't know what to write here! Suggestions welcome
## Motivation
This PR unifies the async execution infrastructure between GPUI and
other components that depend on the `scheduler` crate (such as our cloud
codebase). By having a scheduler that lives independently of GPUI, we
can enable deterministic testing across the entire stack - testing GPUI
applications alongside cloud services with a single, unified scheduler.
## Summary
This PR completes the integration of the `scheduler` crate into GPUI,
unifying async execution and enabling deterministic testing of GPUI
combined with other components that depend on the scheduler crate.
## Key Changes
### Scheduler Integration (Phases 1-5, previously completed)
- `TestDispatcher` now delegates to `TestScheduler` for timing, clock,
RNG, and task scheduling
- `PlatformScheduler` implements the `Scheduler` trait for production
use
- GPUI executors wrap scheduler executors, selecting `TestScheduler` or
`PlatformScheduler` based on environment
- Unified blocking logic via `Scheduler::block()`
### Dead Code Cleanup
- Deleted orphaned `crates/gpui/src/platform/platform_scheduler.rs`
(older incompatible version)
## Intentional Removals
### `spawn_labeled` and `deprioritize` removed
The `TaskLabel` system (`spawn_labeled`, `deprioritize`) was removed
during this integration. It was only used in a few places for test
ordering control.
cc @maxbrunsfeld @as-cii - The new priority-weighted scheduling in
`TestScheduler` provides similar functionality through
`Priority::High/Medium/Low`. If `deprioritize` is important for specific
test scenarios, we could add it back to the scheduler crate. Let me know
if this is blocking anything.
### `start_waiting` / `finish_waiting` debug methods removed
Replaced by `TracingWaker` in `TestScheduler` - run tests with
`PENDING_TRACES=1` to see backtraces of pending futures when parking is
forbidden.
### Realtime Priority removed
The realtime priority feature was unused in the codebase. I'd prefer to
reintroduce it when we have an actual use case, as the implementation
(bounded channel with capacity 1) could potentially block the main
thread. Having a real use case will help us validate the design.
## Testing
- All GPUI tests pass
- All scheduler tests pass
- Clippy clean

Always missed the ability to clear the search without having to reach
for my keyboard if I'm on a mouse-first workflow:

/>
Release Notes:
- Added a button to clear the search query for the collab and outline
panels' search bar.
There were several places adding a copy icon button, so thought of
encapsulating the logic to copy a given string into the clipboard (and
other small details like swapping the icon and tooltip if copied) into a
component, making it easier to introduce this sort of functionality in
the future, with fewer lines of code.
All it takes (for the simplest case) is:
```rs
CopyButton::new(your_message)
```

Closes #ISSUE
Problem:
- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.
Fix:
- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

Release Notes:
- Fixed: pending keybinding prefixes on the status bar now clear
immediately when focus moves to another panel or UI context.

This PR removes the actions `collab::ToggleScreenSharing`,
`collab::ToggleMute`, and `collab::ToggleDeafen`. They weren't actually
registered to any behavior, so while it was possible to create a keybind
bound to them, they never actually trigger. I spent ~30 minutes trying
to figure out why I was getting this result for my `"f13":
"collab::ToggleMute"` keybind in the keybind context menu:
<img width="485" height="174" alt="image"
src="https://github.com/user-attachments/assets/23064c8f-fe8d-42e5-b94f-bd4b8a0cb3b5"
/>
(This really threw me for a loop because I was trying to use this as a
known good case to compare against a _different_ action that wasn't
working because I forgot to register it.)
As a side benefit, this enables telemetry for toggling mic mute via
keybind.
Release Notes:
- Fixed telemetry for `collab::Mute`
- Removed unregistered actions `collab::ToggleMute`,
`collab::ToggleDeafen`, and `collab::ToggleScreenshare`
- The correctly-functioning actions `collab::Mute`, `collab::Deafen`,
and `collab::ScreenShare` are recommended instead
Gist is we only need to block the foreground thread for reparsing if
immediate language changes are useful to the user. That is usually only
the case when they edit the buffer

This PR finally removes the `CheckboxWithLabel` component, which is not
fully needed given the `Checkbox` can take a `label` method. Then, took
advantage of the opportunity to add more methods with regards to label
customization (position, size, and color) in both the `Checkbox` and
`Switch` components.

This mostly affects the collab and outline panels for now. It has always
been a bit weird that the search field was at the bottom of the panel,
even more so because in both cases, you can _arrow down_ to start
navigating the list with your keyboard. So, with the search at the
bottom, you'd arrow down and get to the top of the list, which was very
strange. Now, with it at the top, it not only looks better but it is
also more generally consistent with other surfaces in the app, like
pickers, the settings UI, rules library, etc. Most search fields are
always at the top.

This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

Adds an action to open the notes for the currently selected channel in
the collab panel, which is mapped to `alt-enter` in all platforms.
Release Notes:
- collab: Add `collab_panel::OpenSelectedChannelNotes` action
(`alt-enter` by default)
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)

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
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
I love keybindings.
I spend way to much time thinking about them.
I also REALLY like working in Zed.
so far, however, I have found the key context system in Zed to be less
flexible than in VSCode.
the HUGE context that is available in VSCode helps you create
keybindings for very specific targeted scenarios.
the tree like structure of the Zed key context means you loose some
information as focus moves throughout the application.
For example, it is not currently possible to create a keybinding in the
editor that will only work when one of the Docks is open, or if a
specific dock is open.
this would be useful in implementing solutions to ideas like #24222
we already have an action for moving focus to the dock, and we have an
action for opening/closing the dock, but to my knowledge (very limited
lol) we cannot determine if that dock *is open* unless we are focused on
it.
I think it is possible to create a more flexible key binding system by
adding more context information to the higher up context ancestors.
while:
```
Workspace right_dock=GitPanel
Dock
GitPanel
Editor
```
may seem redundant, it actually communicates fundamentally different
information than:
```
Workspace right_dock=GitPanel
Pane
Editor
```
the first says "the GitPanel is in the right hand dock AND IT IS
FOCUSED",
while the second means "Focus is on the Editor, and the GitPanel just
happens to be open in the right hand dock"
This change adds a new set of identifiers to the `Workspace` key_context
that will indicate which docks are open and what is the specific panel
that is currently visible in that dock.
examples:
- `left_dock=ProjectPanel`
- `bottom_dock=TerminalPanel`
- `right_dock=GitPanel`
in my testing the following types of keybindings seem to be supported
with this change:
```jsonc
// match for any value of the identifier
"context": "Workspace && bottom_dock"
"context": "Workspace && !bottom_dock"
// match only a specific value to an identifier
"context": "Workspace && bottom_dock=TerminalPanel"
// match only in a child context if the ancestor workspace has the correct identifier
"context": "Workspace && !bottom_dock=DebugPanel > Editor"
```
some screen shots of the context matching in different circumstances:

the persistent_name values for `ProjectPanel` and `OutlinePanel` needed
to be updated to not have a space in them in order to pass the
`Identifier` check. all the other Panels already had names that did not
include spaces, so it just makes these conform with the other ones.
I think this is a great place to start with adding more context
identifiers and i think this type of additional information will make it
possible to create really dynamic keybindings!
Release Notes:

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.

We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

Before this change the active theme and icon theme were retrofitted onto
the ThemeSettings.
Now they're in their own new global (GlobalTheme::theme(cx) and
GlobalTheme::icon_theme(cx))
This lets us remove cx from the settings traits, and tidy up a few other
things along the way.

serde 1.0.221 introduced serde_core into the build graph, which should
render explicitly depending on serde_derive for faster build times an
obsolote method.
Besides, I'm not even sure if that worked for us. My hunch is that at
least one of our deps would have `serde` with derive feature enabled..
and then, most of the crates using `serde_derive` explicitly were also
depending on gpui, which depended on `serde`.. thus, we wouldn't have
gained anything from explicit dep on `serde_derive`

At RustConf we were demo'ing zed, and it continually popped open the
chat panel.
We're usually inured to this because the Chat panel doesn't open unless
a Guest
is in the channel, but it made me sad that we were showing a long stream
of
vacuous comments and unresponded to questions on every demo screen.
We may bring chat back in the future, but we need more thought on the
UX, and
we need to rebuild the backend to not use the existing collab server
that we're
trying to move off of.
Release Notes:
- Removed the chat feature from Zed (Sorry to the 5 of you who use this
on the regular!)
Follow-up to https://github.com/zed-industries/zed/pull/37489
Notification panel settings were always missing the content, hence this
PR adds it. After #37489, the use of the same content twice broke
things, which currently makes the notification panel non-configurable on
Nightly. This PR fixes this.
There once was an issue about the documentation for the panel being
wrong as well. However, I was just unable to find that sadly.

This PR separates out the associated constant `KEY` from the `Settings`
trait into a new trait `SettingsKey`. This allows for the key trait to
be derived using attributes to specify the path so that the new
`SettingsUi` derive macro can use the same attributes to determine top
level settings paths thereby removing the need to duplicate the path in
both `Settings::KEY` and `#[settings_ui(path = "...")]`

This PR introduces the `display_options` field in the
`CompletionResponse`, allowing a code context menu width to be
dynamically dictated based on its larger item. This will allow us to
have the @-mentions and slash commands completion menus in the agent
panel not be bigger than it needs to be. It may also be relevant/useful
in the future for other use cases.
For now, we set all instances of code context menus to use a fixed
width, as defined in the PR linked above, which means this PR shouldn't
cause any visual change.

Closes #ISSUE
Initially, the `SettingsUi` trait was tied to `Settings`, however, given
that the `Settings::FileContent` type (which may be the same as the type
that implements `Settings`) will be the type that more directly maps to
the JSON structure (and therefore have the documentation, correct field
names (or `serde` rename attributes), etc) it makes more sense to have
the deriving of `SettingsUi` occur on the `FileContent` type rather than
the `Settings` type.
In order for this to work a relatively important change had to be made
to the derive macro, that being that it now "unwraps" options into their
inner type, so a field with type `Option<Foo>` where `Foo: SettingsUi`
will treat the field as if it were just `Foo`, expecting there to be a
default set in `default.json`. This imposes some restrictions on what
`Settings::FileContent` can be as seen in 1e19398 where `FileContent`
itself can't be optional without manually implementing `SettingsUi`, as
well as introducing some risk that if the `FileContent` type has
`serde(default)`, the default value will override the default value from
`default.json` in the UI even though it may differ (but it should!).
A future PR should probably replace the other settings with `FileContent
= Option<T>` (all of which currently have `T == bool`) with wrapper
structs and have `KEY = None` so the further niceties
`derive(SettingsUi)` will provide such as path renaming, custom UI, auto
naming and doc comment extraction can be used.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
## Goal
This PR creates the initial settings ui structure with the primary goal
of making a settings UI that is
- Comprehensive: All settings are available through the UI
- Correct: Easy to understand the underlying JSON file from the UI
- Intuitive
- Easy to implement per setting so that UI is not a hindrance to future
settings changes
### Structure
The overall structure is settings layer -> data layer -> ui layer.
The settings layer is the pre-existing settings definitions, that
implement the `Settings` trait. The data layer is constructed from
settings primarily through the `SettingsUi` trait, and it's associated
derive macro. The data layer tracks the grouping of the settings, the
json path of the settings, and a data representation of how to render
the controls for the setting in the UI, that is either a marker value
for the component to use (avoiding a dependency on the `ui` crate) or a
custom render function.
Abstracting the data layer from the ui layer allows crates depending on
`settings` to implement their own UI without having to add additional UI
dependencies, thus avoiding circular dependencies. In cases where custom
UI is desired, and a creating a custom render function in the same crate
is infeasible due to circular dependencies, the current solution is to
implement a marker for the component in the `settings` crate, and then
handle the rendering of that component in `settings_ui`.
### Foundation
This PR creates a macro and a trait both called `SettingsUi`. The
`SettingsUi` trait is added as a new trait bound on the `Settings`
trait, this allows the type system to guarantee that all settings
implement UI functionality. The macro is used to derived the trait for
most types, and can be modified through attributes for unique cases as
well.
A derive-macro is used to generate the settings UI trait impl, allowing
it the UI generation to be generated from the static information in our
code base (`default.json`, Struct/Enum names, field names, `serde`
attributes, etc). This allows the UI to be auto-generated for the most
part, and ensures consistency across the UI.
#### Immediate Follow ups
- Add a new `SettingsPath` trait that will be a trait bound on
`SettingsUi` and `Settings`
- This trait will replace the `Settings::key` value to enable
`SettingsUi` to infer the json path of it's derived type
- Figure out how to render `Option<T> where T: SettingsUi` correctly
- Handle `serde` attributes in the `SettingsUi` proc macro to correctly
get json path from a type's field and identity
