Tim VermeulenandLukas Wirth 7a8a328d3c editor: Preserve the selection granularity when extending a selection (#39759)
Currently when extending a selection using shift-click, the selection
granularity (or `SelectMode`) is based on the click count when extending
the selection, not on the click count of the initial selection. For
example, selecting a word with double-click followed by shift-click uses
a character granularity:


https://github.com/user-attachments/assets/13c78bb9-9c31-45d4-97de-99c30c7425a7

This PR changes this behavior to be more in line with other editors that
I'm familiar with by preserving the granularity of the initial selection
(unless the extension has a higher click count, i.e. the behavior of a
single click selection by a shift-double-click extension is unchanged):


https://github.com/user-attachments/assets/92e69e95-7ea2-4f76-b0a4-e4b9efa1947b

Release Notes:

- Extending a selection using shift-click now preserves the
character/word/line granularity of the initial selection

Munish MummadiandHactarCE 096930817b Make FoldAtLevel commands discoverable in command palette (#39422)
## Description
Fixes #39376

Add individual FoldAtLevel1-9 actions so users can find fold commands in
the command palette while keeping existing keybindings.

Migrating user keymaps is necessary to have the keybinds show in the command palette.

Closes #39376 

### Changes
- `crates/editor/src/actions.rs` - Added FoldAtLevel1-9 action structs
- `crates/editor/src/editor.rs` - Implemented fold_at_level_1-9 handler
methods
- `crates/editor/src/element.rs` - Registered new actions
- `assets/keymaps/*.json` - Updated keybindings to use new individual
actions

### Other Approaches considered
- Adding #[serde(default)] to existing FoldAtLevel(u32) - wouldn't make
it discoverable
- Creating a single action with enumerated variants - idk about this
that well.

### Release Notes
Release Notes:
- Added Fold At Level 1-9 actions to the command palette

Lukas Wirth fc0b249136 multi_buffer: Fix handling of ExcerptId::max() (#38887)
This removes a hack from `MultiBuffer::anchor_at` that works around
missing logic for handling `ExcerptId::max()` by implementing that said
missing logic.

Generally, `ExcerptId::min()` is already being handled correctly due to
how `Cursor` seeking works, we tend to seek to or beyond a seek target,
meaning `min` will always match the first excerpt as expected. `max` on
the other hand will always seek beyond the last excerpt resulting in no
excerpt being found, so any code path dealing with the excerpt sumtree
will have to specially check for this special excerpt ID to work
correctly.

Tim VermeulenandJoseph T. Lyons 42ef3e5d3d editor: Make cmd-alt-click behavior more consistent (#38733)
Fixes two inconsistencies around the behavior of cmd-alt-click that mess
with my VSCode muscle memory:
- The definition is opened in a pane to the right of the current pane,
unless there exists an adjacent pane to the left and not to the right,
in which case it's opened in the pane on the left
- In case Go to Definition needs to open a multibuffer, cmd-alt-click
does not open it in an existing pane to the right of the current pane,
it always creates a new pane directly to the right of the current pane

This PR irons out this behavior by always going to the definition in the
pane directly to the right of the current one, creating one only if one
doesn't yet exist.

If changing `Workspace::adjacent_pane` to not consider an existing pane
to the left is undesirable then that logic could be moved somewhere
else, or we can make it user configurable if necessary. Also happy to
split this PR up if either of these changes is controversial 🙂

Ben KunkleandMichael 4aac5642c1 JSON Schema URIs (#38916)
Closes #ISSUE

Improves the efficiency of our interactions with the Zed language
server. Previously, on startup and after every workspace configuration
changed notification, we would send >1MB of JSON Schemas to the JSON
LSP. The only reason this had to happen was due to the case where an
extension was installed that would result in a change to the JSON schema
for settings (i.e. added language, theme, etc).

This PR changes the behavior to use the URI LSP extensions of
`vscode-json-language-server` in order to send the server URI's that it
can then use to fetch the schemas as needed (i.e. the settings schema is
only generated and sent when `settings.json` is opened. This brings the
JSON we send to on startup and after every workspace configuration
changed notification down to a couple of KB.

Additionally, using another LSP extension request we can notify the
server when a schema has changed using the URI as a key, so we no longer
have to send a workspace configuration changed notification, and the
schema contents will only be re-requested and regenerated if the schema
is in use.

Release Notes:

- Improved the efficiency of communication with the builtin JSON LSP.
JSON Schemas are no longer sent to the JSON language server in their
full form. If you wish to view a builtin JSON schema in the language
server info tab of the language server logs (`dev: open language server
logs`), you must now use the `editor: open url` action with your cursor
over the URL that is sent to the server.
- Made it so that Zed urls (`zed://...`) are resolved locally when
opened within the editor instead of being resolved through the OS. Users
who could not previously open `zed://*` URLs in the editor can now do so
by pasting the link into a buffer and using the `editor: open url`
action (please open an issue if this is the case for you!).

Lauren Hinchcliffe 301e976465 Fix inlay hints using status theming instead of syntax theming (#36219)
Release Notes:

- Fixed editor inlay hints incorrectly using status theming when syntax
theming is available

Previously, a theme's `style.syntax.hint` object is completely ignored,
and `style.hint` `style.hint.background` are used instead. However,
these seem to be related to status hints, such as the inline git blame
integration.

For syntax hints (as given by an LSP), the reasonable assumption would
be that the `style.syntax.hint` object is used instead, but it isn't.
This means that defining other style characteristics (`font_style`, for
example) does nothing.

I've fixed the issue in a backward-compatible way, by using the theme
`syntax` `HighlightStyle` as the base for inlay hint styling, and
falling back to the original `status` colors should the syntax object
not contain the color definitions.

 With the following theme settings:
```jsonc
{
  "hint": "#ff00ff",                    // Status hints (git blame, etc.)
  "hint.background": "#ff00ff10",
  "syntax": {
    "hint": {
      "color": "#ffffff",               // LSP inlay hints
      "background_color": "#ffffff10",
      "font_style": "italic",           // Now properly applied
      "font_weight": 700
    }
  }
}
```


Current behavior:
<img width="896" height="201" alt="image"
src="https://github.com/user-attachments/assets/e89d212f-ed7e-4d27-94e4-96d716e229d2"
/>

Italics and font weight are ignored. Uses status colors instead.

Fixed behavior:
<img width="896" height="202" alt="image"
src="https://github.com/user-attachments/assets/f14ed2c3-bb60-4b74-886d-6b409d338714"
/>

Italics and font weight are used properly. Status color is preserved for
the git blame status, but correct syntax colors are used for the inlay
hints.

03f9cf4414 Represent relative paths using a dedicated, separator-agnostic type (#38744)
Closes https://github.com/zed-industries/zed/issues/38690
Closes #37353

### Background

On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.

Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.

### Solution

Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.

The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).

- N/A

DinoandConrad Irwin 2759f541da vim: Fix cursor position being set to end of line in normal mode (#38161)
Address an issue where, in Vim mode, clicking past the end of a line
after selecting the entire line would place the cursor on the newline
character instead of the last character of the line, which is
inconsistent with Vim's normal mode expectations.

I believe the root cause was that the cursor’s position was updated to
the end of the line before the mode switch from Visual to Normal, at
which point `DisplayMap.clip_at_line_ends` was still set to `false`. As
a result, the cursor could end up in an invalid position for Normal
mode. The fix ensures that when switching between these two modes, and
if the selection is empty, the selection point is properly clipped,
preventing the cursor from being placed past the end of the line.

Related #38049 

Release Notes:

- Fixed issue in Vim mode where switching from any mode to normal mode
could end up with the cursor in the newline character

Joseph T. LyonsandCole Miller c88fdaf02d Implement Markdown link embedding on paste (#38639)
This PR adds automatic markdown URL embedding on paste when you are in
text associated with the Markdown language and you have a valid URL in
your clipboard. This the default behavior in VS Code and GitHub, when
pasting a URL in Markdown. It works in both singleton buffers and multi
buffers.

One thing that is a bit unfortunate is that, previously, `do_paste` use
to simply call `Editor::insert()`, in the case of pasting content that
was copied from an external application, and now, we are duplicating
some of `insert()`'s logic in place, in order to have control over
transforming the edits before they are inserted.

Release Notes:

- Added automatic Markdown URL embedding on paste.

Smit Barmase 86834887da editor: Fix completions menu flashes on every keystroke in TSX files with emmet (#38320)
Closes https://github.com/zed-industries/zed/issues/37774

Bug in https://github.com/zed-industries/zed/pull/32927

Instead of using trigger characters to clear cached completions items,
now we check if the query is empty to clear it. Turns out Emmet defines
whole [alphanumeric as trigger
characters](https://github.com/olrtg/emmet-language-server/blob/279be108725fb391c167690b697ce154fd32657b/index.ts#L116)
which causes flickering.

Clear on trigger characters was introduced to get rid of cached
completions like in the case of "Parent.Foo.Bar", where "." is one of
the trigger characters. This works still since "." is not part of
`completion_query_characters` and hence we use it as a boundary while
building the current query. i.e in this case, the query would be empty
after typing ".", clearing cached completions.

Release Notes:

Cole Miller c27d8e0c7a editor: Don't pull diagnostics on excerpts change in diagnostics editors (#38212)
This can lead to an infinite regress when using a language server that
supports pull diagnostics, since the excerpts for the diagnostics editor
are set based on the project's diagnostics.

Closes #36772

Release Notes:

- Fixed a bug that could cause duplicated diagnostics with some language
servers.

Finn Evers ded6467604 Refactor the scrollbar component (#36105)
Closes https://github.com/zed-industries/zed/issues/37621
Improves https://github.com/zed-industries/zed/issues/24623

Adding scrollbars withing Zed's UI currently is rather cumbersome, as it
requires the copying of a lot of code in order for these to work. Wiring
up settings for scrollbar visibilty always has to be done at the call
site and the state has to be saved and maintained by the caller as well.
Similarly, reserving space has to also be handled by the caller.

This PR changes the way scrollbars work in Zed fundamentally by making
use of the new `use_keyed_state` APIs: Instead of saving the state at
the call site, the window now keeps track of the state corresponding to
scrollbars. This enables us to add scrollbars with e.g. one simple call
on divs:
```rust
div()
    .vertical_scrollbar(window, cx)
```
will add a scrollbar to the corresponding container. There are some more
improvements regarding tracking of scrollbar visibility settings (which
is now handled by a trait for each setting that supports this) as well
as reserving space.
Additionally, all needed stuff for layouting, catching events and
reserving space is also now managed by the scrollbar component instead.
This drastically reduces the amount of event listeners and makes
layouting of two scrollbars easier.

Furthermore, this paves the way for more improvements to scrollbars,
such as graceful auto-hide. Only downsight here is that we lose some
customizability in a few areas. However, once this lands, we gain the
ability to quickly follow these up without breaking stuff elsewhere.

This also already fixes a few bugs:
- Scrollbars no longer flicker on first render. 
- Auto-hide now properly works for all scrollbars.
- If the content size changes, the scrollbar is updated on the same
frame. Both of these happened because we were computing the scrollbar
sizes too early, causing us to use the sizes from the previous frame or
unitialized sizes.
- The project panel no longer jumps if scrolled all the way to the
bottom and the scrollbar actually auto-hides.

Still TODO:
- [x] Fix scrolling in the debugger memory view
- [x] Clean up some more in the scrollbar component and reduce clones
there
- [x] Ensure we don't over-notify the entity the scrollbar is rendered
within
- [x] Make sure auto-hide properly works for all cases
- [x] Check whether we want to implement the scrollbar trait for
`UniformList`s as well
    - ~~ [ ] Use for uniformlist where possible~~ Postponed
- [x] Improve layout for cases where we render both scrollbars.

Release Notes:

- N/A

Lukas Wirth 462293667b editor: Re-use multibuffers when opening the same locations again (#37994)
A very primitive attempt, we just key the editor with the locations and
re-use the editor if we open a new buffer with the same initial
locations and title.

Release Notes:

- Added reusing of reference search buffers when applicable
