Closes#21822
## Context
Exposes `preferred_line_length` from `AllLanguageSettings` to the
Extension
API's `LanguageSettings` struct. Currently only `tab_size` is available
to
extensions, which prevents language extensions (e.g. Dart) from reading
the
user's preferred line length and forwarding it to their language server
(e.g. as `dart.lineLength`).
Related: https://github.com/zed-extensions/dart/issues/2
## How to Review
Small change — follow how `tab_size` is plumbed through:
1. WIT definition (`language-settings` record)
2. `extension_api` Rust struct
3. Host-side bridge conversion
The new field follows the exact same pattern.

(This should be merged after #48332)
This PR exposes the LSP settings schema functionality to extensions,
allowing them to provide JSON schema for `initialization_options` and
`settings` fields to enable autocomplete in settings files.
New extension API methods (v0.8.0+):
- `language_server_initialization_options_schema`
- `language_server_settings_schema`
Both methods return an optional JSON string conforming to JSON schema.
Older extension versions gracefully return `None`.
Release Notes:
- Added support for settings schemas for the next version of the
extension API so that settings autocompletion can be provided for
language server settings.

Round 2 of #46269 with conflicts properly resolved.
This came up a few times across various extensions. With us about to
ship a new API version soon, it might be worth to add.

Some language servers include local symbols (e.g., local variables,
parameters) in workspace symbol results. Without the `containerName`
information, these symbols lack context information, making it difficult
to distinguish them from top-level definitions and hindering efficient
symbol lookup.
This change exposes the `container_name` field from LSP
[`SymbolInformation`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#symbolInformation)
to the extension API, allowing language server extensions to access
`symbol.container_name` in `label_for_symbol` and provide meaningful
context when rendering symbol labels.
Note: The `container_name `field is added to all extension API versions
because they seem to share the same underlying Rust types via wasmtime
bindgen. The field is optional, so existing extensions would remain
compatible as far as I understand.
Closes #ISSUE
Release Notes:
- Added `container_name` field to `lsp::Symbol`, accessible via the
extension API's `label_for_symbol` function

Extension authors frequently guard this method in their extensions
although this is not necessary.
Thus, this PR updates the documentation of `make_file_executable` with a
brief mention to indicate that this is not needed.
Release Notes:
- N/A
This PR forks a new version of the `zed_extension_api` in preparation
for new changes.
We're jumping from v0.6.0 to v0.8.0 for the WIT because we released
v0.7.0 of the `zed_extension_api` without any WIT changes (it probably
should have been v0.6.1, instead).
Release Notes:
- N/A
- DAP schemas will be stored in `debug_adapters_schemas` subdirectory in
extension work dir.
- Added Debug Config integration and such.
Release Notes:
- N/A
This allows us to support debugging with a debug adapter not managed by
Zed. Note that this is not a user facing change, as DebugAdapterBinary
is used to determine how to spawn a debugger. Thus, this should not
break any configs or anything like that.
Closes #ISSUE
Release Notes:
- N/A
This PR allows DAPs to define their own schema so users can see
completion items when editing their debug.json files.
Users facing this aren’t the biggest chance, but behind the scenes, this
affected a lot of code because we manually translated common fields from
Zed's config format to be adapter-specific. Now we store the raw JSON
from a user's configuration file and just send that.
I'm ignoring the Protobuf CICD error because the DebugTaskDefinition
message is not yet user facing and we need to deprecate some fields in
it.
Release Notes:
- debugger beta: Show completion items when editing debug.json
- debugger beta: Breaking change, debug.json schema now relays on what
DAP you have selected instead of always having the same based values.

Extensions cannot look up available port themselves, hence the new API.
With this I'm able to port our Ruby implementation into an extension.

This PR exposes context server settings to extensions.
Extensions can use `ContextServerSettings::for_project` to get the
context server settings for the current project.
The `experimental.context_servers` setting has been removed and replaced
with the `context_servers` setting (which is now an object instead of an
array).

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);
```

This PR changes v0.0.7 of the extension API to v0.1.0.
We had a false-start in releasing v0.0.7, which has since been yanked,
so we need a new version number. We'll publish v0.1.0 to crates.io once
the Preview build is out tomorrow.
We're incrementing the minor version so that we have some leeway in
putting out patch releases of the crate within a given extension API
release.

# HTTP Client Improvements for Extension API
This PR enhances the HTTP client functionality in the Zed extension API,
providing more control over requests and allowing for streaming
responses.
## Key Changes
1. Extended `HttpRequest` struct:
- Added `method` field to specify HTTP method
- Added `headers` field for custom headers
- Added optional `body` field for request payload
2. Introduced `HttpMethod` enum for supported HTTP methods
3. Updated `HttpResponse` struct:
- Added `headers` field to access response headers
- Changed `body` type from `String` to `Vec<u8>` for binary data support
4. Added streaming support:
- New `fetch_stream` function to get a response stream
- Introduced `HttpResponseStream` resource for chunked reading
5. Updated internal implementations to support these new features
6. Modified the Gleam extension to use the new API structure
## Motivation
These changes provide extension developers with more flexibility and
control over HTTP requests. The streaming support is particularly useful
for handling large responses efficiently or ideally streaming into the
UI.
## Testing
- [x] Updated existing tests
- [ ] Added new tests for streaming functionality
## Next Steps
- Consider adding more comprehensive examples in the documentation
- Evaluate performance impact of streaming for large responses
Please review and let me know if any adjustments are needed.

This PR updates the extension API to make the `worktree` argument to
`run_slash_command` optional.
We may not always have a worktree, and not all slash commands need them,
so by making it optional we can allow individual slash commands to
decide what to do when there is no worktree.
Release Notes:
- N/A
This PR updates the extension API to use structured slash command
completions instead of plain strings.
This allows slash commands defined in extensions to take advantage of
the improvements made in #13876.
Release Notes:
- N/A
This PR adds a new `fetch` function to the `zed_extension_api` to allow
fetching a URL through the Wasm host.
Currently we only support GET requests and return the response body as a
string.
Release Notes:
- N/A
This PR extends the interface for slash commands defined in extensions
to have them return `SlashCommandOutput`.
This allows for slash commands to return multiple output sections for a
single piece of generated text.
Note that we don't allow specifying the icon to display in the
placeholder, as we don't want to commit to that in our API at the
moment.
Release Notes:
- N/A
- Confirming a completion now runs the command immediately
- Hitting `enter` on a line with a command now runs it
- The output of commands gets folded away and replaced with a custom
placeholder
- Eliminated ambient context

This PR adds initial support for defining slash commands for the
Assistant from extensions.
Slash commands are defined in an extension's `extension.toml`:
```toml
[slash_commands.gleam-project]
description = "Returns information about the current Gleam project."
requires_argument = false
```
and then executed via the `run_slash_command` method on the `Extension`
trait:
```rs
impl Extension for GleamExtension {
// ...
fn run_slash_command(
&self,
command: SlashCommand,
_argument: Option<String>,
worktree: &zed::Worktree,
) -> Result<Option<String>, String> {
match command.name.as_str() {
"gleam-project" => Ok(Some("Yayyy".to_string())),
command => Err(format!("unknown slash command: \"{command}\"")),
}
}
}
```

Improves documentation for `CodeLabel.filter_range` in
`zed_extension_api` by clarifying that it's a range of only the text
displayed in the label, *not* the `code` field.
Release Notes:

This PR adds the ability for extensions to implement
`language_server_workspace_configuration` to provide workspace
configuration to the language server.
We've used the Dart extension as a motivating example for this, pulling
it out into an extension in the process.
Release Notes:
- Removed built-in support for Dart, in favor of making it available as
an extension. The Dart extension will be suggested for download when you
open a `.dart` file.
