For the extension devs:
Adds a `RebuildDevExtension` action that triggers a rebuild of an
installed dev extension.
- If no dev extensions are installed, shows an error notification.
- If exactly one dev extension is installed, rebuilds it immediately.
- If multiple dev extensions are installed, opens a fuzzy picker to
select which one to rebuild.
Makes it easy for devs to trigger a rebuild with a keymap once an action
is defined with this PR.

We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.
Release Notes:
- N/A
This adds a "workspace-hack" crate, see
[mozilla's](https://hg.mozilla.org/mozilla-central/file/3a265fdc9f33e5946f0ca0a04af73acd7e6d1a39/build/workspace-hack/Cargo.toml#l7)
for a concise explanation of why this is useful. For us in practice this
means that if I were to run all the tests (`cargo nextest r
--workspace`) and then `cargo r`, all the deps from the previous cargo
command will be reused. Before this PR it would rebuild many deps due to
resolving different sets of features for them. For me this frequently
caused long rebuilds when things "should" already be cached.
To avoid manually maintaining our workspace-hack crate, we will use
[cargo hakari](https://docs.rs/cargo-hakari) to update the build files
when there's a necessary change. I've added a step to CI that checks
whether the workspace-hack crate is up to date, and instructs you to
re-run `script/update-workspace-hack` when it fails.
Finally, to make sure that people can still depend on crates in our
workspace without pulling in all the workspace deps, we use a `[patch]`
section following [hakari's
instructions](https://docs.rs/cargo-hakari/0.9.36/cargo_hakari/patch_directive/index.html)
One possible followup task would be making guppy use our
`rust-toolchain.toml` instead of having to duplicate that list in its
config, I opened an issue for that upstream: guppy-rs/guppy#481.
TODO:
- [x] Fix the extension test failure
- [x] Ensure the dev dependencies aren't being unified by Hakari into
the main dependencies
- [x] Ensure that the remote-server binary continues to not depend on
LibSSL

Because of #26562, it is now possible to subscribe to extension update
events within the LSP store, where we can then update the Schemas sent
to the JSON LSP resulting in dynamic updates to the auto-complete
suggestions and diagnostics in settings. Notably, this means newly
installed languages and (icon) themes will auto-complete correctly as
soon as the extension is installed.
Closes#15436
Release Notes:
- Fixed an issue where autocomplete suggestions and diagnostics for
languages and (icon) themes in settings would not update when the
extension with which they were added was installed or uninstalled
This PR adds a new `ExtensionEvents` event bus that can be used to
listen for extension-related events throughout the app.
Today you need to have a handle to the `ExtensionStore` (which entails
depending on `extension_host`) in order to listen for extension events.
With this change subscribers only need to depend on `extension`, which
has a leaner dependency graph.
Release Notes:
- N/A
This PR adds the general structure for filtering the extensions list by
what the extensions provide.
Currently flagged for Zed staff until we get some design direction on
how best to present the filter.
Release Notes:

This PR overhauls extension registration in order to make it more
modular.
The `extension` crate now contains an `ExtensionHostProxy` that can be
used to register various proxies that the extension host can use to
interact with the rest of the system.
There are now a number of different proxy traits representing the
various pieces of functionality that can be provided by an extension.
The respective crates that provide this functionality can implement
their corresponding proxy trait in order to register a proxy that the
extension host will use to register the bits of functionality provided
by the extension.
Release Notes:
- N/A
This PR updates the extension context server registration to go through
the `Extension` trait for interacting with extensions rather than going
through the `WasmHost` directly.
Release Notes:
- N/A
This PR extracts the `VimModeSetting` out of the `vim` crate and into
its own `vim_mode_setting` crate.
A number of crates were depending on the entirety of the `vim` crate
just to reference `VimModeSetting`, which was not ideal.
Release Notes:
- N/A
This PR removes a dependency on the `extensions_ui` from the `title_bar`
crate.
This dependency only existed to reference the `Extensions` action, which
has now been moved to the `zed_actions` crate.
This allows `title_bar` to move up in the crate dependency graph.
Release Notes:
- N/A
This PR moves the tests for the `ExtensionStore` back into the
`extension_host` crate.
We now have a separate `TestExtensionRegistrationHooks` to use in the
test that implements the minimal required functionality needed for the
tests. This means that we can depend on the `theme` crate only in the
tests.
Release Notes:
- N/A
This optimizes and fixes bugs in our logic for maintaining a set of
running context servers, based on the combination of the user's
`context_servers` settings and their installed extensions.

This PR extracts the `ExtensionIndexedDocsProvider` implementation to
the `indexed_docs` crate.
To achieve this, we introduce a new `Extension` trait that provides an
abstracted interface for calling an extension. This trait resides in the
`extension` crate, which has minimal dependencies and can be depended on
by other crates, like `indexed_docs`.
We're then able to implement the `ExtensionIndexedDocsProvider` without
having any knowledge of the Wasm-specific internals of the extension
system.
Release Notes:
- N/A
This fixes the issue of multiple language servers showing up as `node`
in the language server logs dropdown.
It does this by changing `language_server.name()` to return the
adapter's name, not the binary name, and changing types to make sure
that we always use this.
Release Notes:
- Fixed language server names showing up only as `"node"`

This PR adds support for context servers provided by extensions.
To provide a context server from an extension, you need to list the
context servers in your `extension.toml`:
```toml
[context_servers.my-context-server]
```
And then implement the `context_server_command` method to return the
command that will be used to start the context server:
```rs
use zed_extension_api::{self as zed, Command, ContextServerId, Result};
struct ExampleContextServerExtension;
impl zed::Extension for ExampleContextServerExtension {
fn new() -> Self {
ExampleContextServerExtension
}
fn context_server_command(&mut self, _context_server_id: &ContextServerId) -> Result<Command> {
Ok(Command {
command: "node".to_string(),
args: vec!["/path/to/example-context-server/index.js".to_string()],
env: Vec::new(),
})
}
}
zed::register_extension!(ExampleContextServerExtension);
```
Release Notes:
- N/A
This contains the main changes to the extensions crate from #20049. The

This PR renames the `extension` crate to `extension_host`.
This is to free up the name so that we can create a smaller-scoped
`extension` crate.

This PR extends the extensions page with support for upselling built-in
Zed features when certain keywords are searched for.
This should help inform users about features that Zed has out-of-the-box
when they go looking for them as extensions.
For example, when someone searches "vim":
<img width="1341" alt="Screenshot 2024-07-15 at 4 58 44 PM"
src="https://github.com/user-attachments/assets/b256d07a-559a-43c2-b491-3eca5bff436e">
Here are more examples of what the upsells can look like:

src="https://github.com/user-attachments/assets/1f453132-ac14-4884-afc4-7c12db47ad1d">
Release Notes:
- Added banners for built-in Zed features when corresponding keywords
are used in the extension search.
This PR adjusts the extension download counts to be displayed using
thousands separators.
Release Notes:
- Adjusted extension download counts to display with thousands
separators (e.g., `1,000,000`).
This PR restricts usage of v0.0.7 of the `zed_extension_api` to dev
builds, for now.
As we're still making changes to it, we don't want to ship a version of
Zed to Preview/Stable that claims to support a yet-unreleased version of
the extension API.
Release Notes:
- N/A
This PR extracts the `SemanticVersion` out of `util` and into its own
`SemanticVersion` crate.
This allows for making use of `SemanticVersion` without needing to pull
in some of the heavier dependencies included in the `util` crate.
As part of this the public API for `SemanticVersion` has been tidied up
a bit.
Release Notes:
- N/A
* [x] auto update extensions on startup
* [ ] add a manual way of updating all?
* [x] add a way to opt out of auto-updates for a particular extension
We don't believe that there should be any background polling for
extension auto-updates, because it could be disruptive to the user.
Release Notes:
- Added an auto-update system for extensions.

This PR adds an `zed: Install Local Extension` action, which lets you
select a path to a folder containing a Zed extension, and install that .
When you select a directory, the extension will be compiled (both the
Tree-sitter grammars and the Rust code for the extension itself) and
installed as a Zed extension, using a symlink.
### Details
A few dependencies are needed to build an extension:
* The Rust `wasm32-wasi` target. This is automatically installed if
needed via `rustup`.
* A wasi-preview1 adapter WASM module, for building WASM components with
Rust. This is automatically downloaded if needed from a `wasmtime`
GitHub release
* For building Tree-sitter parsers, a distribution of `wasi-sdk`. This
is automatically downloaded if needed from a `wasi-sdk` GitHub release.
The downloaded artifacts are cached in a support directory called
`Zed/extensions/build`.
### Tasks
UX
* [x] Show local extensions in the Extensions view
* [x] Provide a button for recompiling a linked extension
* [x] Make this action discoverable by adding a button for it on the
Extensions view
* [ ] Surface errors (don't just write them to the Zed log)
Packaging
* [ ] Create a separate executable that performs the extension
compilation. We'll switch the packaging system in our
[extensions](https://github.com/zed-industries/extensions) repo to use
this binary, so that there is one canonical definition of how to
build/package an extensions.

This PR moves the Clippy configuration up to the workspace level.
We're using the [`lints`
table](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-lints-table)
to configure the Clippy ruleset in the workspace's `Cargo.toml`.
Each crate in the workspace now has the following in their own
`Cargo.toml` to inherit the lints from the workspace:
```toml
[lints]
workspace = true
```
This allows for configuring rust-analyzer to show Clippy lints in the
editor by using the following configuration in your Zed `settings.json`:
```json
{
"lsp": {
"rust-analyzer": {
"initialization_options": {
"check": {
"command": "clippy"
}
}
}
}
```
Release Notes:
- N/A
- Moves languages module from `zed` into a separate crate. That way we
have less of a long pole at the end of compilation.
- Removes moot dependencies on editor/picker. This is totally harmless
and might help in the future if we decide to decouple picker from
editor.
Before:
```
Number of crates that depend on 'picker' but not on 'editor': 1
Total number of crates that depend on 'picker': 13
Total number of crates that depend on 'editor': 30
```
After:
```
Number of crates that depend on 'picker' but not on 'editor': 5
Total number of crates that depend on 'picker': 12
Total number of crates that depend on 'editor': 26
```
The more crates depend on just picker but not editor, the better in that
case.
Release Notes:
- N/A
This PR adds a view for installing extensions within Zed.
