Release Notes:

- Added support for Google's Gemini 2.0 Flash experimental model.

Note:

Weirdly enough the model is slow on small talk responses like 'hi' (in
my tests) but very fast on things that need more tokens like 'write me a
snake game in python'. Likely an API problem.

TESTED ONLY ON WINDOWS! Would test further but don't have Linux
installed and don't have an Mac. Will likely work everywhere.

Why?:

I think Gemini 2.0 Flash is incredibly good model at coding and
following instructions. I think it would be nice to have it in the
editor. I did as minimal changes as possible while adding the model and
streaming validation. I think it's worth merging the commits as they
bring good improvements.

This will allow the diagnostic popover to be displayed even if hovering
an invisible char.

Beyond that, it solves a rare `DiagnosticPopover` corner case:

* Supports moving the selection to a diagnostic when `GoToDiagnostic` is
done while hovering, based on `group_id`

* Provides Diagnostic values with `group_id: 0` providing information on
hover about invisible characters.

So, `GoToDiagnostic` would navigate to the very first error produced by
a language server. Really not a big deal of course.

Closes #22433

Before/After (macOS):

![CleanShot 2024-12-26 at 22 41
11@2x](https://github.com/user-attachments/assets/1701da2e-3db7-4dd1-a680-0f63824cbdf5)

For some reason the non-blurred one seems much lower quality, so we may
need to tinker with the samples, or something else.

12@2x](https://github.com/user-attachments/assets/5a43330d-137b-4d45-a67a-fd10ef6a8ff8)

I'm unsure if this is a problem on Linux/in the Blade renderer, but
since no changes were made outside of the medal shaders we can probably
take this macOS-specific win for now.

Release Notes:

- gpui: Fixed an issue where shadows with a `blur_radius` of 0 would not
render.

This PR adds timeouts when resolving feature flags during workspace
panel initialization so that we don't block indefinitely if Zed is not
connected to the internet.

Right now we wait for 5 seconds, but this value was chosen arbitrarily.

Release Notes:

- Closes: https://github.com/zed-industries/zed/issues/22699
- Refine the key binding for `cmd-shift-e` (macOS) / `ctrl-shift-e`
(linux)
- Now Works after closing the final buffer
- Now Works from other panels (Terminal/Assistant/Collab/Chat/etc)

Follow-up to:
- https://github.com/zed-industries/zed/pull/21228

Release Notes:

- Fixed Project Panel toggle (`cmd-shift-e` / `ctrl-shift-e`) so it
works in more contexts.

Namely, just removing the unnecessary extra line dividers and adding a
super subtle background color to the diagnostic message to create a bit
of separation/hierarchy.

This reverts commit 3ae6aa0e4dbc21c09c14d7bb92b4c52cf480d39f.

If "group_id = 0" really did mean a diagnostic not from a language
server then various methods related to diagnostic set would need to be
updated. Something like [this
diff](https://gist.github.com/mgsloan/e902153bcaec207b39260a8f40d3134d).

Plan instead is to use InfoPopover instead of DiagnosticPopover for
these.

Release Notes:

No need to find or store the primary range ahead of time as it's found
by `activate_diagnostics`.

Not entirely sure we should still even have the special case when the
popover is visible. It does support the keyboard interaction of opening
hover followed by jumping to the primary position, but that seems pretty
undiscoverable.

Support for clicking the hover to navigate to the primary diagnostic was
removed in https://github.com/zed-industries/zed/pull/3408

Release Notes:

Should resolve https://github.com/zed-industries/zed/issues/21714.

In some conditions that I'm not sure of, Zed sends LSP requests with
`start > end` position, and zls has an [assertion for end >=
start](https://github.com/zigtools/zls/blob/f253553b8230ecd94824ecc3e2da2eb1643e7512/src/offsets.zig#L492),
and that causes zls to crash, like:

In LSP specification for
[`Range`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#range)
type, it says:
> ... If you want to specify a range that contains a line including the
line ending character(s) then use an end position denoting the start of
the next line.

I feel like zls's assertion is sensible, so I've updated the generic
`range_to_lsp` function rather than doing something specific to zls. But
let me know if this seems incorrect.

zls was crashing after 5-10 minutes of working with a Zig codebase
before, and after this change, I tested for an hour and didn't
experience any crashes.

Release Notes:

- Ensure `end >= start` in `lsp::Range`, which should fix Zig/zls
crashes.

In particular, `DiagnosticPopover` both:

* Supports moving the selection to a diagnostic when clicked, based on
`group_id`

* Provides Diagnostic values with `group_id: 0` providing informztion on
hover about invisible characters.

So, clicking such a popover would navigate to the very first error
produced by a language server. Really not a big deal of course, but
seems good to fix as it might result in surprising behavior in other
future circumstances

In #22620 `diagnostic_group` was modified to return results for
multibuffers, but was returning singleton buffer points. `hover_popover`
uses it to find the jump target for clicking the popup - which doesn't
seem to be working right now but that's a separate issue. Now that
`diagnostic_group` is returning values in multibuffers converting these
to anchors was crashing.

Also resolves a potential bug - if folding in multibuffers was supported
then "Go To Diagnostics" would not properly skip diagnostics from folded
regions.

Closes #15705

When opening a file from the terminal, if the file path is relative, we
attempt to guess all possible paths where the file could be. This
involves generating paths for each worktree, the current terminal
directory, etc. For example, if we have two worktrees, `dotfiles` and
`example`, and `foo.txt` in `example/a`, the generated paths might look
like this:

- `/home/tims/dotfiles/../example/a/foo.txt` from the `dotfiles`
worktree
- `/home/tims/example/../example/a/foo.txt` from the `example` worktree
- `/home/tims/example/a/foo.txt` from the current terminal directory
(This is already canonicalized)

Note that there should only be a single path, but multiple paths are
created due to missing canonicalization.

Later, when opening these paths, the worktree prefix is stripped, and
the remaining path is used to open the file in its respective worktree.

As a result, the above three paths would resolve like this:

- `../example/a/foo.txt` as the filename in the `dotfiles` worktree
(Ghost file)
- `../example/a/foo.txt` as the filename in the `example` worktree
(Ghost file)
- `foo.txt` as the filename in the `a` directory of the `example`
worktree (This opens the file)

This PR fixes the issue by canonicalizing these paths before adding them
to the HashSet.

Closes #22607

Symlinks can be absolute or relative. When using
[stow](https://www.gnu.org/software/stow/) to manage dotfiles, it
creates relative symlinks to the target files.

For example:  

- Original file:  `/home/tims/dotfiles/zed/setting.json`  
- Symlink path: `/home/tims/.config/zed/setting.json`  
- Target path (relative to symlink): `../../dotfiles/zed/setting.json`  

The issue is that you can’t watch the symlink path because it’s relative
and doesn't include the base path it is relative to. This PR fixes that
by converting relative symlink paths to absolute paths.

- Absolute path (after parent join):
`/home/tims/.config/zed/../../dotfiles/zed/setting.json` (This works)
- Canonicalized path (from absolute path):
`/home/tims/dotfiles/zed/setting.json` (This works too, just more
cleaner)

Release Notes:

- Fix issue where items on the Welcome page could not be toggled on
Linux when using Stow to manage dotfiles

Closes #22326

This PR adds process PID information to window created by X11, so that
window manager can identify which process this window belongs to.
Without this property, the window manager would have no reliable way to
know which process created this window.

In original issue, `robotgo` throws error on `x, y, w, h :=
robotgo.GetBounds(pid)` this method. If we go deeper into the source
code of `robotgo`, it calls `GetXidFromPid` which goes through all
windows, and tries to check for provided pid. Hence, when it tries to do
that for Zed, it fails and returns `0, err` to caller.

```go
// Robotgo source code trying to look through all windows and query pid

// GetXidFromPid get the xid from pid
func GetXidFromPid(xu *xgbutil.XUtil, pid int) (xproto.Window, error) {
	windows, err := ewmh.ClientListGet(xu)
	if err != nil {
		return 0, err
	}

	for _, window := range windows {
		wmPid, err := ewmh.WmPidGet(xu, window)
		if err != nil {
			return 0, err
		}

		if uint(pid) == wmPid {
			return window, nil
		}
	}

	return 0, errors.New("failed to find a window with a matching pid.")
}
```

Querying for pid for active Zed window:

Before:
```sh
tims@lemon ~/w/go-repro [127]> xprop -root _NET_ACTIVE_WINDOW
_NET_ACTIVE_WINDOW(WINDOW): window id # 0x4e00002
tims@lemon ~/w/go-repro> xprop -id 0x4e00002 _NET_WM_PID
_NET_WM_PID:  not found.
```

After:
```sh
tims@lemon ~/w/go-repro> xprop -root _NET_ACTIVE_WINDOW
_NET_ACTIVE_WINDOW(WINDOW): window id # 0x4e00002
tims@lemon ~/w/go-repro> xprop -id 0x4e00002 _NET_WM_PID
_NET_WM_PID(CARDINAL) = 103548
tims@lemon ~/w/go-repro>
```

Correct zed process PID (below) assosiated with zed window (shown
above):

Release Notes:

- Fix `robotgo` failing when Zed window is open on Linux

Closes #22578

Currently, the `hovered` boolean in the window state is only updated by
the `WM_MOUSELEAVE` event, which fires when the mouse cursor leaves the
window's working area. This means that when the user moves the cursor
from the window to the title bar, `hovered` is set to `false`. Later in
the code, this flag is used to determine the cursor style and check if
the cursor is over the correct window.

The `hovered` boolean should remain active even when the mouse is over
non-client items, such as the title bar or window borders. This PR fixes
that by using `WM_NCMOUSELEAVE` event, which is triggered when the mouse
leaves non-client items. This event is used to update the `hovered`
boolean accordingly.

Now, `hovered` is `true` when the mouse is over the window's working
area, as well as non-client areas like the title bar.

More context:

- Existing: `dwFlags: TME_LEAVE` tracks window area mouse leaves, which
is used in `handle_mouse_move_msg` func.
- New: `dwFlags: TME_LEAVE | TME_NONCLIENT` tracks non-client mouse
leaves, which is used in `handle_nc_mouse_move_msg` func.

This PR is a continuation of [linux: Implement
Menus](https://github.com/zed-industries/zed/pull/21873) and should only
be reviewed once the existing PR is merged.

I created this as a separate PR as the existing PR was already reviewed
but is yet to merge, and also it was my initial plan to do it in
separate parts because of the scope of it. This will also help reviewing
code faster.

This PR adds two new types of keyboard shortcuts to make menu navigation
easier:

1. `Alt + Z` for Zed, `Alt + F` for File, `Alt + S` for Selection, and
so on to open a specific menu with this combination. This mimics VSCode
and IntelliJ.

2. `Arrow Left/Right` when any menu is open. This will trigger the
current menu to close, and the previous/next to open respectively. First
and last element cycling is handled.

`Arrow Up/Down` to navigate menu entries is already there in existing
work.
