This implements some of #10457.

Release notes:

- Added `g c c` and `g c` to Vim keybindings to toggle comments in
normal and visual mode respectively.
- Added `g ]` and `g [` to Vim keybindings to go to next and previous
diagnostic error.
- Changed `[ x` and `] x` (which select larger/smaller syntax node) in
Vim mode to also work in visual mode.

Release Notes:

- Added a notification to show possible `git blame` errors if it fails to run.

Caveats:
- ~git blame now executes in foreground
executor  (required since the Fut is !Send)~

TODOs:
- After a failed toggle, the app thinks the blame
is shown. This means toggling again will do nothing
instead of retrying. (Caused by editor.show_git_blame
being set to true before the git blame is generated)
- ~(Maybe) Trim error?~ Done

This also adds some "responsiveness" so that UI elements are hidden
before everything has to be occluded

Release Notes:

- Improved search UI. It now works in narrower panes, and avoids
scrolling the editor on open.

Release Notes:

- Added the current operator stack to the Vim status bar at the bottom
of the editor. #4447

This commit introduces a new feature that displays the current partial
command in the vim mode, similar to the behavior in Vim plugin. This
helps users keep track of the commands they're entering.

It's wierd to type code/regex in the UI font

Release Notes:

- Continue to use buffer font for search

This design polish PR brings the project panel context menu into better
alignment with other editors, better follows system patterns and
identifies focus shifting actions with the `…` indicator (like adding a
new folder to a project, which will open a modal window.)

Release Notes:

- N/A

With the recent Linux rewrite, I attempted to simplify the number of
wrapper structs involved in the Linux code, following the macOS code as
an example. Unfortunately, I missed a vital component: pointers to the
platform state, held by platform data structures. As we hold all of the
platform data structures on Linux, this PR reintroduces a wrapper around
the internal state of both the platform and the window. This allows us
to close and drop windows correctly.

This PR also fixes a performance problem introduced by:
https://github.com/zed-industries/zed/pull/10343, where each configure
request would add a new frame callback quickly saturating the main
thread and slowing everything down.

Release Notes:

- Added private alpha support for remote development. Please reach out to hi@zed.dev if you'd like to be part of shaping this feature.

This PR implements the preview tabs feature from VSCode.
More details and thanks for the head start of the implementation here
#6782.

Here is what I have observed from using the vscode implementation ([x]
-> already implemented):
- [x] Single click on project file opens tab as preview
- [x] Double click on item in project panel opens tab as permanent
- [x] Double click on the tab makes it permanent
- [x] Navigating away from the tab makes the tab permanent and the new
tab is shown as preview (e.g. GoToReference)
- [x] Existing preview tab is reused when opening a new tab
- [x] Dragging tab to the same/another panel makes the tab permanent
- [x] Opening a tab from the file finder makes the tab permanent
- [x] Editing a preview tab will make the tab permanent
- [x] Using the space key in the project panel opens the tab as preview
- [x] Handle navigation history correctly (restore a preview tab as
preview as well)
- [x] Restore preview tabs after restarting
- [x] Support opening files from file finder in preview mode (vscode:
"Enable Preview From Quick Open")
 
I need to do some more testing of the vscode implementation, there might
be other behaviors/workflows which im not aware of that open an item as
preview/make them permanent.

Showcase:


https://github.com/zed-industries/zed/assets/53836821/9be16515-c740-4905-bea1-88871112ef86


TODOs
- [x] Provide `enable_preview_tabs` setting
- [x] Write some tests
- [x] How should we handle this in collaboration mode (have not tested
the behavior so far)
- [x] Keyboard driven usage (probably need workspace commands)
- [x] Register `TogglePreviewTab` only when setting enabled?
- [x] Render preview tabs in tab switcher as italic
- [x] Render preview tabs in image viewer as italic
- [x] Should this be enabled by default (it is the default behavior in
VSCode)?
- [x] Docs

Future improvements (out of scope for now):
- Support preview mode for find all references and possibly other
multibuffers (VSCode: "Enable Preview From Code Navigation")


Release Notes:

- Added preview tabs

I've found it a bit annoying that autogenerated code shows up in
completions when working on Zed, so I've moved them into an associated
function of a struct we're "implementing" Action on. That way, neither a
generated function nor a static show up in completions.

Note that this change only affects Zed codebase! I'm pushing it up right
after last Preview to give it some time on Nightly.

When I installed zed by running `brew install zed` following
`README.md`, [brimdata/zed](https://github.com/brimdata/zed) was

Fixes #7694
The new setting accepts "last_workspace" (default) and "none" as
options.

In a follow-up PR I'll add a new option that re-launches all of the Zed
windows and not just the last one.

Release Notes:

- Added `restore_on_startup` option, accepting `last_workspace`
(default) and `none` options. With `none`, new Zed instances will not
restore workspaces that were open last.

the tab switcher is open.

This PR updates Danger to proxy its requests to GitHub through a proxy
service.

## Motivation

Currently Danger is not able to run on PRs opened from forks of Zed.

This is due to GitHub Actions' security policies. Forks are not able to
see any of the repository secrets, and the built-in
`secrets.GITHUB_TOKEN` has its permissions
[restricted](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token)
to only reads when running on forks.

I asked around on the Danger repo, and some big projects
(DefinitelyTyped) are working around this by using a publicly-listed
(although slightly obfuscated) token:
https://github.com/danger/danger-js/issues/918#issuecomment-2048629487.

While this approach is _probably_ okay given the limited scope and
permissions of the GitHub token, I would still prefer a solution that
avoids disclosing the token at all.

## Explanation

I ended up writing a small proxy service, [Danger
Proxy](https://github.com/maxdeviant/danger-proxy), that can be used to
provide Danger with the ability to make authenticated GitHub requests,
but without disclosing the token.

From the README:

> Danger Proxy will:
>
> - Proxy all requests to `/github/*` to the GitHub API. The provided
GitHub API token will be used for authentication.
> - Restrict requests to the list of repositories specified in the
`ALLOWED_REPOS` environment variable.
> - Restrict requests to the subset of the GitHub API that Danger
requires.

I have an instance of this service deployed to
[danger-proxy.fly.dev](https://danger-proxy.fly.dev/).

New list (used tasks are above the separator line, sorted by the usage
recency), then all language tasks, then project-local and global tasks
are listed.
Note that there are two test tasks (for `test_name_1` and `test_name_2`
functions) that are created from the same task template:

Tasks are deduplicated by labels, with the used tasks left in case of
the conflict with the new tasks from the template:

retrieved, no cargo tests for function are listed in tasks:

Part of https://github.com/zed-industries/zed/issues/10132
Reworks the task code to simplify it and enable proper task labels.

* removes `trait Task`, renames `Definition` into `TaskTemplate` and use
that instead of `Arc<dyn Task>` everywhere
* implement more generic `TaskId` generation that depends on the
`TaskContext` and `TaskTemplate`
* remove `TaskId` out of the template and only create it after
"resolving" the template into the `ResolvedTask`: this way, task
templates, task state (`TaskContext`) and task "result" (resolved state)
are clearly separated and are not mixed
* implement the logic for filtering out non-related language tasks and
tasks that have non-resolved Zed task variables
* rework Zed template-vs-resolved-task display in modal: now all reruns
and recently used tasks are resolved tasks with "fixed" context (unless
configured otherwise in the task json) that are always shown, and Zed
can add on top tasks with different context that are derived from the
same template as the used, resolved tasks
* sort the tasks list better, showing more specific and least recently
used tasks higher
* shows a separator between used and unused tasks, allow removing the
used tasks same as the oneshot ones
* remote the Oneshot task source as redundant: all oneshot tasks are now
stored in the inventory's history
* when reusing the tasks as query in the modal, paste the expanded task
label now, show trimmed resolved label in the modal
* adjusts Rust and Elixir task labels to be more descriptive and closer
to bash scripts

Release Notes:

- Improved task modal ordering, run and deletion capabilities

Added additional tests to cover other folder names in regards to
[#10193](https://github.com/zed-industries/zed/issues/10193) and
[#9729](https://github.com/zed-industries/zed/issues/9729).

I had a similar issue but with folder names like '2.5' and '2.5_backup'.
I didn't see test coverage for those kinds of file names, so wanted to
add them.

Closes https://github.com/zed-industries/zed/issues/10380

Release Notes:

- Fixed Zed panicking when running tasks via a keybinding
([10380](https://github.com/zed-industries/zed/issues/10380))

This PR reworks the way workspace notifications are identified to use a
new `NotificationId` type.

A `NotificationId` is bound to a given type that is used as a unique
identifier. Generally this will be a unit struct that can be used to
uniquely identify this notification.

A `NotificationId` can also accept an optional `ElementId` in order to
distinguish between different notifications of the same type.

This system avoids the issue we had previously of selecting `usize` IDs
somewhat arbitrarily and running the risk of having two independent
notifications collide (and thus interfere with each other).

This also fixes a bug where multiple suggestion notifications for the
same extension could be live at once

Fixes https://github.com/zed-industries/zed/issues/10320.

Release Notes:

Currently in Zed, certain characters require pressing the key twice to
move the caret through that character. For example: "❤️" and "y̆".

The reason for this is as follows:

Currently, Zed uses `chars` to distinguish different characters, and
calling `chars` on `y̆` will yield two `char` values: `y` and `\u{306}`,
and calling `chars` on `❤️` will yield two `char` values: `❤` and
`\u{fe0f}`.

Therefore, consider the following scenario (where ^ represents the
caret):

- what we see: ❤️ ^
- the actual buffer: ❤ \u{fe0f} ^

After pressing the left arrow key once:

- what we see: ❤️ ^
- the actual buffer: ❤ ^ \u{fe0f}

After pressing the left arrow key again:
- what we see: ^ ❤️
- the actual buffer: ^ ❤ \u{fe0f}

Thus, two left arrow key presses are needed to move the caret, and this
PR fixes this bug (or this is actually a feature?).

I have tried to keep the scope of code modifications as minimal as
possible. In this PR, Zed handles such characters as follows:

- what we see: ❤️ ^
- the actual buffer: ❤ \u{fe0f} ^

After pressing the left arrow key once:

- what we see: ^ ❤️
- the actual buffer: ^ ❤ \u{fe0f}

Or after pressing the delete key:

- what we see: ^
- the actual buffer: ^

Please note that currently, different platforms and software handle
these special characters differently, and even the same software may
handle these characters differently in different situations. For
example, in my testing on Chrome on macOS, GitHub treats `y̆` as a
single character, just like in this PR; however, in Rust Playground,
`y̆` is treated as two characters, and pressing the delete key does not
delete the entire `y̆` character, but instead deletes `\u{306}` to yield
the character `y`. And they both treat `❤️` as a single character,
pressing the delete key will delete the entire `❤️` character.

This PR is based on the principle of making changes with the smallest
impact on the code, and I think that deleting the entire character with
the delete key is more intuitive.

Release Notes:

- Fix caret movement issue for some special characters

This PR fixes a potential panic that could occur when loading malformed
Wasm files.

We now use the `parse_wasm_extension_version` function that was
previously used just to extract the Zed extension API version from the
Wasm bytes as a pre-validation step. By parsing the entirety of the Wasm
file here instead of returning as soon as we find the version, the
invalid Wasm bytes are now surfaced as an `Err` instead of a panic.

We were able to replicate the panic using the following test:

```rs
#[gpui::test]
async fn test_bad_wasm(cx: &mut TestAppContext) {
    init_test(cx);

    let wasm_host = cx.update(|cx| {
        WasmHost::new(
            FakeFs::new(cx.background_executor().clone()),
            FakeHttpClient::with_200_response(),
            FakeNodeRuntime::new(),
            Arc::new(LanguageRegistry::test(cx.background_executor().clone())),
            PathBuf::from("/the/work/dir".to_string()),
            cx,
        )
    });

    let mut wasm_bytes = std::fs::read("/Users/maxdeviant/Library/Application Support/Zed/extensions/installed/dart/extension.wasm").unwrap();

    // This is the error message we were seeing in the stack trace:
    // range end index 267037 out of range for slice of length 253952

    dbg!(&wasm_bytes.len());

    // Truncate the bytes to the same point:
    wasm_bytes.truncate(253952);

    std::fs::write("/tmp/bad-extension.wasm", wasm_bytes.clone()).unwrap();

    let manifest = Arc::new(ExtensionManifest {
        id: "the-extension".into(),
        name: "The Extension".into(),
        version: "0.0.1".into(),
        schema_version: SchemaVersion(1),
        description: Default::default(),
        repository: Default::default(),
        authors: Default::default(),
        lib: LibManifestEntry {
            kind: None,

        },
        themes: Default::default(),
        languages: Default::default(),
        grammars: Default::default(),
        language_servers: Default::default(),
    });

    // 💥
    let result = wasm_host
        .load_extension(wasm_bytes, manifest, cx.executor())
        .await;
    dbg!(result.map(|_| ()));

This reverts commit 53d0cc61460fde18469e415596acd8d77d92f7c5.

This PR updates the `GITHUB_TOKEN` environment variable that we use for
Danger so that it should (hopefully) be able to run for PRs of external
contributors.

Followed the instructions outlined

There hasn't been a componentized way to create inputs or text fields

We'll continue to evolve this component in the near future and start
using it in the app once we've built out the needed functionality.
