TODO:
- [x] Use AsyncFn instead of Fn() -> Future in GPUI spawn methods
- [x] Implement it in the whole app
- [x] Implement it in the debugger
- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.
- [ ] Fix platform specific code
Release Notes:
- N/A
Release Notes:
- Fixed involuntary joining of lines when typing in the commit message
editor
- Fixed being unable to type whitespace after a comment character at the
start of a line in the commit message editor
### DISCLAIMER
> As of 6th March 2025, debugger is still in development. We plan to
merge it behind a staff-only feature flag for staff use only, followed
by non-public release and then finally a public one (akin to how Git
panel release was handled). This is done to ensure the best experience
when it gets released.
### END OF DISCLAIMER

Closes#25458
When navigating code from a preview tab with
`enable_preview_from_code_navigation` set to `true`, "Go Back" from a
newly opened tab could focus on the tab to the right instead of
returning to the original preview tab.
Before, we killed the existing preview tab before opening a new one,
which breaking history as the new tab had no reference to the old one.
This caused navigation to shift to the next tab on the right.
Now, we first add the new tab at the preview index, and then kill the
existing preview tab. This preserves the history by linking new preview
tab to existing tab.
Release Notes:
- Fixes an issue where navigating code from a preview tab with
`enable_preview_from_code_navigation` set to `true`, "Go Back" from a
newly opened tab could focus on the tab to the right instead of
returning to the original preview tab.
Similar to how tasks are fetched via LSP, also queries for document's
code lens and filters the ones with the commands, supported in server
capabilities.
Whatever's left and applicable to the range given, is added to the
actions menu:

This way, Zed can get more actions to run, albeit neither r-a nor vtsls
seem to provide anything by default.
Currently, there are no plans to render code lens the way as in VSCode,
it's just the extra actions that are show in the menu.
------------------
As part of the attempts to use rust-analyzer LSP data about the
runnables, I've explored a way to get this data via standard LSP.
When particular experimental client capabilities are enabled (similar to
how clangd does this now), r-a starts to send back code lens with the
data needed to run a cargo command:
```
{"jsonrpc":"2.0","id":48,"result":{"range":{"start":{"line":0,"character":0},"end":{"line":98,"character":0}},"command":{"title":"▶︎ Run Tests","command":"rust-analyzer.runSingle","arguments":[{"label":"test-mod tests::ecparser","location":{"targetUri":"file:///Users/someonetoignore/work/ec4rs/src/tests/ecparser.rs","targetRange":{"start":{"line":0,"character":0},"end":{"line":98,"character":0}},"targetSelectionRange":{"start":{"line":0,"character":0},"end":{"line":98,"character":0}}},"kind":"cargo","args":{"environment":{"RUSTC_TOOLCHAIN":"/Users/someonetoignore/.rustup/toolchains/1.85-aarch64-apple-darwin"},"cwd":"/Users/someonetoignore/work/ec4rs","overrideCargo":null,"workspaceRoot":"/Users/someonetoignore/work/ec4rs","cargoArgs":["test","--package","ec4rs","--lib"],"executableArgs":["tests::ecparser","--show-output"]}}]}}}
```
This data is passed as is to VSCode task processor, registered in
https://github.com/rust-lang/rust-analyzer/blob/60cd01864a2d0d6e2231becee402ba063b59dfa1/editors/code/src/main.ts#L195
where it gets eventually executed as a VSCode's task, all handled by the
r-a's extension code.
rust-analyzer does not declare server capabilities for such tasks, and
has no `workspace/executeCommand` handle, and Zed needs an interactive
terminal output during the test runs, so we cannot ask rust-analyzer
more than these descriptions.
Given that Zed needs experimental capabilities set to get these lens:
https://github.com/rust-lang/rust-analyzer/blob/60cd01864a2d0d6e2231becee402ba063b59dfa1/editors/code/src/client.ts#L318-L327
and that the lens may contain other odd tasks (e.g. docs opening or
references lookup), a protocol extension to get runnables looks more
preferred than lens:
https://rust-analyzer.github.io/book/contributing/lsp-extensions.html#runnables
This PR does not include any work on this direction, limiting to the
general code lens support.
As a proof of concept, it's possible to get the lens and even attempt to
run it, to no avail:

Release Notes:
- Used `textDocument/codeLens` data in the actions menu when applicable
Fixes the selection highlight appearing in single-line editors like the
file picker, command palette, etc.
Release Notes:
- Fixed selection highlight appearing in input fields like the file
picker, command palette, etc.
Closes#14349
When typing quotes immediately after a word character, it resulted in
auto-closing the quote.
```js
const thing = this is text^;
```
Typing a quote resulted in `this is text""^;` which is not correct, and
should be `this is text"^;`.
This PR changes logic for auto close:
1. We now prevent auto-closing in case of brackets where start == end
when they're typed immediately after a word character. i.e. For, ``` `,
", ' ```.
2. Other bracket pairs like `{}, (), etc` continue to auto-close
regardless of preceding character. So, `func^` to `func()^` will keep
working.
3. Auto-closing in other contexts like after spaces, punctuation, etc.
will still work.
Before:

After:

Release Notes:
- Fixed auto-paired quotes being inserted when typing a quote
immediately next to a word character.
Very small change, simply changing the order of the futures we pass to
`select_biased!` so that if the format request and the timeout resolve
at the same time (highly unlikely) we choose the format request instead
of choosing the timeout and throwing away our work!

Follow-up of https://github.com/zed-industries/zed/pull/26410
* Extract word completions into their own, `editor::ShowWordCompletions`
action so those could be triggered independently of completions
* Assign `ctrl-shift-space` binding to this new action
* Still keep words returned along the completions as in the original PR,
but:
* Tone down regular completions' fallback logic, skip words when the
language server responds with empty list of completions, but keep on
adding words if nothing or an error were returned instead
* Adjust the defaults to wait for LSP completions infinitely
* Skip "words" with digits such as `0_usize` or `2.f32` from completion
items, unless a completion query has digits in it

This PR cleans up some color & elevation misc.
### Don't allow deriving Color from Hsla
The point of the [ui::Color] enum is to encourage consistent color
usage, and the the Color::Custom case is really only meant for cases
where we have no other choice.
`impl From<Hsla> for Color` encourages blindly passing colors into
`Color::Custom` – with this in place we might as well remove the entire
`Color` enum.
The usages that were updated due to this removal were for colors that
already exist in the Color enum, making it even more clear that it
didn't make sense to have this.
### `ElevationIndex` -> `Elevation`
This name would make more sense if we had an `Elevation` in the first
place. The new name is more clear.
#### `Button::elevation`
As part of this change I also updated button's `layer` method to
`elevation`, since it takes an elevation. This method still has the
following issue:
You want to use `Button::elevation` when it's default colors are
invisible on the layer you are rendering the button on. However, current
this method uses the elevation's `bg` color, rather than it's
`on_elevation_bg`.
Ideally when you use `Button::elevation` you want to pass the elevation
you are _on_, not choosing one that will show up the elevation you are
on.
This change will be in a separate PR, as it likely will have widespread
visual impact across the app.
Release Notes:
- N/A
This adds the ability for the editor to implement hard wrap (similar to
"textwidth" in vim).
If you are typing and your line extends beyond the limit, a newline is
inserted before the most recent space on the line. If you are otherwise
editing the line, pasting, etc. then you will need to manually rewrap.
Release Notes:
- git: Commit messages are now wrapped "as you type" to 72 characters.
Closes https://github.com/zed-industries/zed/issues/4957https://github.com/user-attachments/assets/ff491378-376d-48ec-b552-6cc80f74200b
Adds `"completions"` language settings section, to configure LSP and
word completions per language.
Word-based completions may be turned on never, always (returned along
with the LSP ones), and as a fallback if no LSP completion items were
returned.
Future work:
* words are matched with the same fuzzy matching code that the rest of
the completions are
This might worsen the completion menu's usability even more, and will
require work on better completion sorting.
* completion entries currently have no icons or other ways to indicate
those are coming from LSP or from word search, or from something else
* we may work with language scopes more intelligently, group words by
them and distinguish during completions
Release Notes:
- Supported word-based completions

Release Notes:
- Git Beta: improved the stage-and-next and unstage-and-next actions in
the project diff editor to start a commit after acting on the last hunk
Closes#26002
Release Notes:
- Added `multibuffer` key context.
- `cmd-down` and `cmd-shift-down` on Mac now moves to the end of the
last line of a singleton buffer instead of the beginning. In
multibuffers, these now move to the start of the next excerpt.
- Fixed `vim::PreviousSectionEnd` (bound to `[ ]`) to move to the
beginning of the line, matching the behavior of `vim::NextSectionEnd`.
- Added `editor::MoveToStartOfNextExcerpt` and
`editor::MoveToEndOfPreviousExcerpt`.
A preparation for https://github.com/zed-industries/zed/issues/4957 that
pushes all LSP-related data out from the basic completion item, so that
it's possible to create completion items without any trace of LSP
clearly.
Release Notes:
- N/A
This reduces the number of multibuffer syncs from 100,000 to 20,000.
Before this change each editor individually observed the project, so
literally any project change was amplified by the number of editors you
had open.
Now editors listen to their buffers instead of the project, and other
users of `cx.observe` on the project have been updated to use specific
events to reduce churn.
Follow up to #26237
Release Notes:
- Improved performance of Zed in large repos with lots of file system
events.

Closes https://github.com/zed-industries/zed/issues/24914 (again)
Release Notes:
- Fixed an issue where multi-line pasted content was auto-indented
incorrectly if copied from the middle of an existing line.
This PR adds a new rounded/corner border token: `rounded_md` with a
value of 6px.
I feel like I was wanting to use 6px border radius a lot but avoiding
due to it being an arbitrary value... so, not anymore! It's also cool to
have this be consistent with Tailwind v4.

Closes#4271
Implemented by kicking of a task on the main thread at the end of
`Editor::handle_input` which waits for the buffer to be re-parsed before
checking if JSX tag completion possible based on the recent edits, and
if it is then it spawns a task on the background thread to generate the
edits to be auto-applied to the buffer
Release Notes:
- Added support for auto-closing of JSX tags

# Problem
Currently, the default soft wrap mode of an editor is determined by
reading the language-specific settings of the language _at offset zero_
in the editor's (multi)buffer. While this provides a way to pick a
single soft wrap mode for a multi-language multibuffer, it's a bad
choice for a single-buffer multibuffer that begins with a different
embedded language. For example, Markdown with frontmatter:
```markdown
---
my_front_matter
---
# Hello World
```
Setting this in config:
```json
"languages": {
"Markdown": { "soft_wrap": "bounded" }
},
```
Will not soft wrap the Markdown file as the language at offset zero is
YAML.
# Solution
Instead of using the language at offset zero, use the language of the
first buffer in the multibuffer (the buffer at offset zero). This gives
better behavior for single-buffer editors, and a similar default for
multi-language multibuffers as before.
# Testing
All existing `editor` crate tests pass, but I would appreciate any
guidance for where best to add additional testing.
Release Notes:
- Fixed soft_wrap setting not applying to buffers starting with a
different language

If the user already binds `tab`/`alt-tab`/`alt-l` to a different action
in a conflicting context and hasn't assigned a different keybinding for
`editor::AcceptEditPrediction`, we would show broken popovers with no
bindings:

Instead, they will now see an error-variant of every popover which
includes a tooltip with a short description and buttons to open the
keymap, and open a new docs section explaining the issue in detail and
how to fix it.

Note: I included the docs change in this PR because it's ok to deploy
before the release, as it also applies to existing versions.
Release Notes:
- edit predictions: Improve UX when there's no keybinding for accepting
predictions

This is take 2 on https://github.com/zed-industries/zed/pull/2341 which
was closed due to lack of migrator.
This PR contains rename of following keymap actions:
```sh
1. ["editor::GoToPrevHunk", { "center_cursor": true }] -> ["editor::GoToPreviousHunk", { "center_cursor": true }]
2. "editor::GoToPrevDiagnostic" -> "editor::GoToPreviousDiagnostic"
3. "editor::ContextMenuPrev" -> "editor::ContextMenuPrevious"
4. "search::SelectPrevMatch" -> "search::SelectPreviousMatch"
5. "file_finder::SelectPrev" -> "file_finder::SelectPrevious"
6. "menu::SelectPrev" -> "menu::SelectPrevious"
7. "editor::TabPrev" -> "editor::Backtab"
```
Release Notes:
- Renamed several keymap actions for consistency (e.g., `GoToPrevHunk` →
`GoToPreviousHunk`, `TabPrev` → `Backtab`). Your existing configured
keybindings will still work. You can click **"Backup and Update"** at
the top of your keymap file to easily update to the new actions.
