## Motivation

I :heart: Zed! It's lightning fast and has great UX. I want it to run as
well on all major platforms. I'm currently using Linux most actively.
[Blade](https://github.com/kvark/blade) is a good candidate for
providing GPU access: it supports Vulkan, Metal, and GLES/WebGL. Its
abstraction is extremely thin, while having one of the nicest GPU APIs.
Codebase is also tiny. Checkout [the meetup
recording](https://www.youtube.com/watch?v=63dnzjw4azI&t=623s) from a
year ago.
I believe these projects make a good match :rocket: !

### Why this is a bad idea

If Zed team wants to use off-the-shelf components from Rust ecosystem,
then Blade is certainly at disadvantage here, since it's not widely
used. It would rely on Zed team adding necessary features in a branch,
then maybe upstreaming some of them. That is to say, it's unclear if
this can be avoided with more popular alternatives - being flexible with
any local changes is a good ability.

### Why it's not too bad

Blade uses [WGSL](https://www.w3.org/TR/WGSL) shaders, similar to `wgpu`
and `arcana`, but without the binding decorations. So this aspect of the
product is nicely portable.

This PR adds the initial support for loading extensions in Zed.

### Extensions Directory

Extensions are loaded from the extensions directory.

The extensions directory has the following structure:

```
extensions/
  installed/
    extension-a/
      grammars/
      languages/
    extension-b/
      themes/
  manifest.json
```

The `manifest.json` file is used internally by Zed to keep track of
which extensions are installed. This file should be maintained
automatically, and shouldn't require any direct interaction with it.

Extensions can provide Tree-sitter grammars, languages, and themes.

Github usernames are allowed to contain `-`, but the autocompletion was
not working correctly.
We added `-` as an allowed character for markdown files. We are not
aware of any completions for markdown files, so this should be fine to
add.

This PR changes our approach to initializing the `SystemAppearance` so
that we can do it earlier in the startup process.

Previously we were using the appearance from the window, meaning that we
couldn't initialize the value until we first opened the window.

Now we read the `window_appearance` from the `AppContext`. On macOS this
is backed by the
[`effectiveAppearance`](https://developer.apple.com/documentation/appkit/nsapplication/2967171-effectiveappearance)
on the `NSApplication`.

We currently still watch for changes to the appearance at the window
level, as the only hook I could find in the documentation is
[`viewDidChangeEffectiveAppearance`](https://developer.apple.com/documentation/appkit/nsview/2977088-viewdidchangeeffectiveappearance),
which is at the `NSView` level.

In my testing this makes it so Zed appropriately chooses the correct
light/dark theme on startup.

Previously it wasn't possible to create a keybinding for this action
because it required an argument.

Now the action takes the active item of the pane and if it's a
multi-buffer the first one.

This also adds a default keybinding for Vim mode: `-` will reveal the
file in the project panel.

Fixes #7485.

Release Notes:

palette. ([#7485](https://github.com/zed-industries/zed/issues/7485)).

This was originally just to fix
https://github.com/zed-industries/zed/issues/4354, which I did by just
returning the previous offset in `find_boundary`.. but `find_boundary`
is used in the "insert mode" / normal editor too, so returning the
previous boundary breaks existing functionality in that case.

I was considering a new `find_boundary` function just for some of the
vim motions like this, but I thought that this is straightforward enough
and future Vim functions might need similar logic too.

Release Notes:

- Fixed https://github.com/zed-industries/zed/issues/4354

Fixes: #2750
Fixes: #7457



Release Notes:

- Fixed a hang/panic that could happen rendering a double-width
character in a single-width terminal
([#2750](https://github.com/zed-industries/zed/issues/2750),
[#7457](https://github.com/zed-industries/zed/issues/7457)).

We noticed the following message in my logs when trying to debug some
lag when collaborating:

```
2024-02-06T09:42:09-08:00 [ERROR] error handling message. client_id:3, sender_id:Some(PeerId { owner_id: 327, id: 1123430 }), type:GetCompletions, error:no such connection: 0/0
```

That `0/0` looks like a bogus connection id, constructed via a derived
`Default`. We didn't ever find a code path that would *use* a default
`ConnectionId` and lead to this error, but it did seem like an
improvement to not have a `Default` for that type.

Turns out that Nushell doesn't like `-lic` and `&&`, but works perfectly
fine with `-l -i -c` and `;`, which the other shells do too.

These all work:

    bash -l -i -c 'echo lol; /usr/bin/env -0'
    nu -l -i -c 'echo lol; /usr/bin/env -0'
    zsh -l -i -c 'echo lol; /usr/bin/env -0'
    fish -l -i -c 'echo lol; /usr/bin/env -0'

Release Notes:

- Fixed shell environment not being loaded if Nushell was set as
`$SHELL`.

Tried to match the existing file icons in Zed as much as possible. This
is how it looks:

|  dark  | light  | 
|---|----|
| <img width="183" alt="Screenshot 2024-02-06 at 15 03 57"
src="https://github.com/zed-industries/zed/assets/43472/bd862753-41bb-4ca6-9a44-16b9b1c9591c">
| <img width="180" alt="Screenshot 2024-02-06 at 15 03 14"
src="https://github.com/zed-industries/zed/assets/43472/9df8c589-64b6-49f2-8e15-b43126579a9f">
|

The main challenge is that the tangram is visually quite heavy and
detailed. The existing icons in Zed are designed in a 14px bounding box,
but are a bit smaller themselves. I guess the extra space is reserved
for hanging elements, it probably doesn't make sense to occupy the whole
area.

Simply scaling down an available SVG of the tangram didn't work well.
The individual shapes were not recognizable because the spacing between
them was too thin. I tried removing the spacing and applying different
opacities for each shape, but that didn't yield enough contrast between
the shapes either.

The second approach was to just use the outlines. It sort of worked, but
looked a bit messy in the places when the outlines are denser than the
tangram shapes:

|  dark  | light  | 
|---|----|
| <img width="192" alt="Screenshot 2024-02-05 at 22 55 46"
src="https://github.com/zed-industries/zed/assets/43472/d0029f49-675d-40ac-96d8-788a29706bad">
| <img width="195" alt="Screenshot 2024-02-05 at 22 56 05"
src="https://github.com/zed-industries/zed/assets/43472/d2de922a-70ec-4bd1-9033-db9a5201e9bd">
|

I then tried to remove the main outline and use the maximum space for
the tangram. That let me increase the spacing between the shapes. I also
rounded them a little bit, to make them look similar to other icons from
Zed. The end result looks clean and the shapes are still recognisable.

Approaches I tried next to an existing icon from Zed:

This takes down LLVM IR size of theme_selector from 316k to ~250k. Note
that I do not care about theme_selector in particular, though it acts as
a benchmark for smaller crates to me ("how much static overhead in
compile time does gpui have").

The title is a bit dramatic, so just to shed some light: by leaking a
type I mean forcing downstream crates to codegen it's methods/know about
it's drop code. Since SubscriberSet is no longer used directly in the
generic (==inlineable) methods, users no longer have to codegen `insert`
and co.
