Release Notes:

- Improved the truncation of long author lists and descriptions in the
extensions view.

This PR reverts the addition of extension capabilities from #16953.

While these may end up being useful at some point, after some discussion
they don't seem like the exact fit for what we're looking to do right
now.

This reverts commit 8ec36f1e2bdea337236048170a356ec034eaa046.

Release Notes:

- N/A

This PR adds a section to the extension docs on how to update an
extension.

Moving this over from the docs that used to live in the extensions repo
so that we can have them all in one place.

Before, when using `?` and `#` for backwards search it would initially
search for the previous match, but upon subsequent inputs to `n` and
`N`, `n` is always treated as "forward" and `N` is always treated as
"backward", instead of continuing the search direction.

now, if i use `?` or `#` for backward search, `n` will go to the
previous selection, and `N` will go to the next. Functionality stays the
same for `/` and `*`.

Release Notes:

- vim: Fixed `n` direction after searching backwards

Ensures we sort paths in search the same as we do in panels.

Ideally we'd store things like this in the worktree, but the sort order
depends
on file vs directory, and callers generally don't know which they're
asking for.

- Improved Sublime keymap: Support for switching to individual tabs with `cmd-1` thru `cmd-9` (MacOS) and `alt-1` thru `alt-9` (Linux) matching Sublime behavior.

This improves performance, because we don't render after every single
match/range that was added to the results.

I think for my example search it's twice as fast?

## Release Notes

Release Notes:

- Improved performance of rendering project-search results in the
multi-buffer after finding them.

Also, includes some cleanup -- adds missing flake-compat input and
aligns the nix build module with how nixpkgs does it.

Release Notes:

- Fixed an issue on NixOS package where the wrong binaries were being
patched, leading to missing Wayland libs when launching Zed

This PR updates the `zed_extension_api` to v0.1.0 for the extensions
that live in this repo.

The changes in that version of additive, so none of the extensions need
to change their usage in order to upgrade.

Release Notes:

This is a prototype change to improve latency of local project searches.
It refactors the matcher to keep paths "in-order" so that we don't need
to wait for all matching files to display the first result.

On a test (searching for `<` in zed.dev) it changes the time until first
result from about 2s to about 50ms. The tail latency seems to increase
slightly (from 5s to 7s) so we may want to do more tuning before hitting
merge.

Release Notes:

- reduces latency for first project search result

This PR adds an initial notion of extension capabilities.

Capabilities are used to express the operations an extension is capable
of doing. This will provide further insights into what an extension can
do, as well as provide the ability to grant or deny the set of
capabilities.

Capabilities are defined in the `capabilities` field in the extension
manifest. This field contains an array of capabilities.

Each capability has a `kind` to denote the known capability it
corresponds to. Individual capabilities may have additional fields,
based on the `kind`.

Here's an example of some capabilities:

```toml
capabilities = [
    { kind = "download-file", host = "github.com", path_prefix = "owner/repo" },
    { kind = "npm:install", package = "@vue/language-server" },
]
```

In order to avoid a breaking change, the `capabilities` field is
currently optional and defaults to an empty array. This will allow us to
add support for extensions to define capabilities before we start
enforcing them.

This adds a new action: `editor: toggle inline completions`.

It allows users to toggle inline completions on/off for the current
buffer.

That toggling is not persistent and when the editor is closed, it's
gone.

That makes it easy to disable inline completions for a single text
buffer, for example, even if you want them on for other buffers.

When toggling on/off, the toggling also overwrites any language
settings. So if you have inline completions disabled for Go buffers,
toggling them on takes precedence over those settings.


Release Notes:

- Added a new editor action to allow toggling inline completions
(Copilot, Supermaven) on and off for the current buffer, taking
precedence over any settings.

This is officially my weirdest performance fix to date; With large # of
windows opening app menu could take a lot of time (we're talking few
seconds with 9 windows, a minute with 10 windows). The fix is to make
one method pub(crate).. What?

<img width="981" alt="image"
src="https://github.com/user-attachments/assets/83b26154-0acd-43ef-84b3-4b85cde36120">

We were spending most of the time on clear_pending_keystrokes, which -
funnily enough - called itself recursively. It turned out we have two
methods; `AppContext::clear_pending_keystrokes` and
WindowContext::clear_pending_keystrokes. The former calls the latter,
but - due to the fact that `WindowContext::clear_pending_keystrokes` is
private and `WindowContext` derefs to `AppContext` - `AppContext` one
ended up actually calling itself! The fix is plain and simple - marking
WindowContext one as pub(crate), so that it gets picked up as a method
to call over `AppContext::clear_pending_keystrokes`.

Closes #16895



Release Notes:

- Fixed app menu performance slowdowns when there are multiple windows
open.

***Update**: after rebasing on top of
https://github.com/zed-industries/zed/pull/16915/ (that also changed how
search worked), the results are still good, but not 10x. Instead of
going from 10s to 500ms, it goes from 10s to 3s.*

This improves the performance of project-wide search by an order of
magnitude.

After digging in, @as-cii and I found that opening buffers was the
bottleneck for project-wide search (since Zed opens, parses, ... buffers
when finding them, which is something VS Code doesn't do, for example).
So this PR improves the performance of opening multiple buffers at once.

It does this by doing two things:

- It batches scan-requests in the worktree. When we search, we search
files in chunks of 64. Previously we'd handle all 64 scan requests
separately. The new code checks if the scan requests can be batched and
if so it, it does that.
- It batches `git status` calls when reloading the project entries for
the opened buffers. Instead of calling `git status` for each file, it
calls `git status` for a batch of files, and then extracts the status
for each file.

(It has to be said that I think the slow performance on `main` has been
a regression introduced over the last few months with the changes made
to project/worktree/git. I don't think it was this slow ~5 months ago.
But I also don't think it was this fast ~5 months ago.)
