11281: ide: parallel prime caches r=jonas-schievink a=jhgg
cache priming goes brrrr... the successor to #10149
---
this PR implements a parallel cache priming strategy that uses a topological work queue to feed a pool of worker threads the crates to index in parallel.
## todo
- [x] should we keep the old prime caches?
- [x] we should use num_cpus to detect how many cpus to use to prime caches. should we also expose a config for # of worker CPU threads to use?
- [x] something is wonky with cancellation, need to figure it out before this can merge.

11145: feat: add config to use reasonable default expression instead of todo! when filling missing fields r=Veykril a=bnjjj
Use `Default::default()` in struct fields when we ask to fill it instead of putting `todo!()` for every fields
before:
```rust
pub enum Other {
One,
Two,
}
pub struct Test {
text: String,
num: usize,
other: Other,
}
fn t_test() {
let test = Test {<|>};
}
```
after:
```rust
pub enum Other {
One,
Two,
}
pub struct Test {
text: String,
num: usize,
other: Other,
}
fn t_test() {
let test = Test {
text: String::new(),
num: 0,
other: todo!(),
};
}
```

By changing the scope of this configuration to `machine-overridible`,
this setting becomes fully local for the VS Code instance the user is
running.
Having this setting excluded from syncing should help avoid
inconveniences for users who have VS Code installed on two different
operating systems, where the paths to the language server binary would
very likely mismatch.
Some features of rust-analyzer requires support for custom commands on
the client side. Specifically, hover & code lens need this.
Stock LSP doesn't have a way for the server to know which client-side
commands are available. For that reason, we historically were just
sending the commands, not worrying whether the client supports then or
not.
That's not really great though, so in this PR we add infrastructure for
the client to explicitly opt-into custom commands, via `extensions`
field of the ClientCapabilities.
To preserve backwards compatability, if the client doesn't set the
field, we assume that it does support all custom commands. In the
future, we'll start treating that case as if the client doesn't support
commands.
So, if you maintain a rust-analyzer client and implement
`rust-analyzer/runSingle` and such, please also advertise this via a
capability.
I saw reference to globs in #7755, but it doesn't look like they're
actually supported, and I had to dig through the source to discover
that the folders are relative to the workspace root. Further digging
was required to get VS Code from hanging for long periods trying to
watch giant Bazel folders that had already been excluded from Rust
Analyzer. Hopefully this tweak will save others the confusion :-)
9264: feat: Make documentation on hover configurable r=Veykril a=Veykril
This also implements deprecation support for config options as this renames `hoverActions_linksInHover` to `hover_linksInHover`.

9258: minor: Give `ImportPrefix` variants better config names r=matklad a=Veykril
I feel like `crate` and `self` work better than `by_crate` and `by_self`. The only reason for the current names were that `Self` doesn't work for the variant name on the rust side so I forgot about setting proper config names on serde layer.

9267: fix: Code: update the LSP server without asking r=matklad a=lnicola
Most LSP extensions seem to do the same thing, and this is causing some
confusion for users who don't notice the update prompt before Code hides
it.
9279: minor: Document installation via Homebrew r=matklad a=Svetlitski
`rust-analyzer` can be installed via [Homebrew](https://brew.sh) (AKA`brew`) on macOS. I've added instructions on how to do so to the documentation. Additionally, I added a `.gitignore` rule to ignore the HTML documentation produced by `asciidoctor manual.adoc` so that it is not accidentally checked into `git`.

8873: Implement import-granularity guessing r=matklad a=Veykril
This renames our `MergeBehavior` to `ImportGranularity` as rustfmt has it as the purpose of them are basically the same. `ImportGranularity::Preserve` currently has no specific purpose for us as we don't have an organize imports assist yet, so it currently acts the same as `ImportGranularity::Item`.
We now try to guess the import style on a per file basis and fall back to the user granularity setting if the file has no specific style yet or where it is ambiguous. This can be turned off by setting `import.enforceGranularity` to `true`.
Closes https://github.com/rust-analyzer/rust-analyzer/issues/8870

The new extension allows filtering of workspace symbool lookup
results by search scope or search kind.
Filtering can be configured in 3 different ways:
- The '#' or '*' markers can be added inline with the symbol lookup
query.
The '#' marker means symbols should be looked up in the current
workspace and any dependencies. If not specified, only current
workspace is considered.
The '*' marker means all kinds of symbols should be looked up
(types, functions, etc). If not specified, only type symbols are
returned.
- Each LSP request can take an optional search_scope or search_kind
argument query parameter.
- Finally there are 2 global config options that can be set for all
requests served by the active RA instance.
Add support for setting the global config options to the VSCode
extension.
The extension does not use the per-request way, but it's useful for
other IDEs.
The latest version of VSCode filters out the inline markers, so
currently the only reasonable way to use the new functionality is
via the global config.
8795: Allow semantic tokens for strings to be disabled r=matklad a=djrenren
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7111
Pretty straightforward change, but open to any suggestions if there's a more recommended testing strategy than what I went with.

8624: Automatically detect rust library source file map r=vsrs a=vsrs
This PR adds a new possible `rust-analyzer.debug.sourceFileMap` value:
```json
{
"rust-analyzer.debug.sourceFileMap": "auto"
}
```
I did not make it the default because it uses two shell calls (`rustc --print sysroot` and `rustc -V -v`). First one can be slow (https://github.com/rust-lang/rustup/issues/783)
Fixes#8619

7891: Improve handling of rustc_private r=matklad a=DJMcNab
This PR changes how `rust-analyzer` handles `rustc_private`. In particular, packages now must opt-in to using `rustc_private` in `Cargo.toml`, by adding:
```toml
[package.metadata.rust-analyzer]
rustc_private=true
```
This means that depending on crates which also use `rustc_private` will be significantly improved, since their dependencies on the `rustc_private` crates will be resolved properly.
A similar approach could be used in #6714 to allow annotating that your package uses the `test` crate, although I have not yet handled that in this PR.
Additionally, we now only index the crates which are transitive dependencies of `rustc_driver` in the `rustcSource` directory. This should not cause any change in behaviour when using `rustcSource: "discover"`, as the source used then will only be a partial clone. However, if `rustcSource` pointing at a local checkout of rustc, this should significantly improve the memory usage and lower indexing time. This is because we avoids indexing all crates in `src/tools/`, which includes `rust-analyzer` itself.
Furthermore, we also prefer named dependencies over dependencies from `rustcSource`. This ensures that feature resolution for crates which are depended on by both `rustc` and your crate uses the correct set for analysing your crate.

I have tested this in [priroda](https://github.com/oli-obk/priroda/), and it provides a significant improvement to the development experience (once I give `miri` the required data in `Cargo.toml`)
Todo:
- [ ] Documentation
This is ready to review, and I will add documentation if this would be accepted (or if I get time to do so anyway)

7901: Make extension respect http proxy settings r=matklad a=kamyuentse
This patch makes vscode extension respect proxy settings when fetching release metadata and rust-analyzer binary.
Co-authored-by: Kam Y. Tse <kevin.xjy@gmail.com>
Rather than eagerly converting JSON, we losslessly keep it as is, and
change the shape of user-submitted data at the last moment.
This also allows us to remove a bunch of wrong Defaults
7068: Add VSCode command to view the hir of a function body r=theotherphil a=theotherphil
Will fix https://github.com/rust-analyzer/rust-analyzer/issues/7061. Very rough initial version just to work out where I needed to wire everything up.
@matklad would you be happy merging a hir visualiser of some kind? If so, do you have any thoughts on what you'd like it show, and how?
I've spent very little time on this thus far, so I'm fine with throwing away the contents of this PR, but I want to avoid taking the time to make this more polished/interactive/useful only to discover that no-one else has any interest in this functionality.

6993: Clean up descriptions for settings r=matklad a=rherrmann
Use two consecutive newlines (`\n\n`) to actually continue text on a
new line.
Use proper markup to reference related settings.
Consistently format references to files, command line arguments, etc.
as `code`. Format mentions of UI elements in _italic_.
Fix typos, add missing full-stops, add missing default values.

Configuration is editor-independent. For this reason, we pick
JSON-schema as the repr of the source of truth. We do specify it using
rust-macros and some quick&dirty hackery though.
The idea for syncing truth with package.json is to just do that
manually, but there's a test to check that they are actually synced.
There's CLI to print config's json schema:
$ rust-analyzer --print-config-schema
We go with a CLI rather than LSP request/response to make it easier to
incorporate the thing into extension's static config. This is roughtly
how we put the thing in package.json.
6496: Use builtin scopes more r=matklad a=georgewfraser
VSCode has added more builtin fallback scopes, so we can remove some of our fallback scopes by aligning with their conventions.
Note that the macro scope doesn't seem to actually *work* at the moment. I have filed a bug with VSCode: https://github.com/microsoft/vscode/issues/110150

* Chalk very recently (like an hour ago) merged a fix that prevents rust analyzer from panicking. This allows it to be usable again for code that hits those situations. See #6134, #6145, Probably #6120
5985: Make MergeBehaviour configurable r=jonas-schievink a=Veykril
This should make the newly implemented `MergeBehaviour` for import insertion configurable as roughly outlined in https://github.com/rust-analyzer/rust-analyzer/pull/5935#issuecomment-685834257. For the config name and the like I just picked what came to mind so that might be up for bikeshedding.

4499: CodeLens configuration options r=vsrs a=vsrs
This PR
- adds an option to granularly enable\disable all CodeLens, just like the TypeScript extension.
- fixes a minor bug for doctests. It makes no sense to show `Debug` lens for them as cargo `Can't skip running doc tests with --no-run`.

4448: Generate configuration for launch.json r=vsrs a=vsrs
This PR adds two new commands: `"rust-analyzer.debug"` and `"rust-analyzer.newDebugConfig"`. The former is a supplement to the existing `"rust-analyzer.run"` command and works the same way: asks for a runnable and starts new debug session. The latter allows adding a new configuration to **launch.json** (or to update an existing one).
If the new option `"rust-analyzer.debug.useLaunchJson"` is set to true then `"rust-analyzer.debug"` and Debug Lens will first look for existing debug configuration in **launch.json**. That is, it has become possible to specify startup arguments, env variables, etc.
`"rust-analyzer.debug.useLaunchJson"` is false by default, but it might be worth making true the default value. Personally I prefer true, but I'm not sure if it is good for all value.
----
I think that this PR also solves https://github.com/rust-analyzer/rust-analyzer/issues/3441.
Both methods to update launch.json mentioned in the issue do not work:
1. Menu. It is only possible to add a launch.json configuration template via a debug adapter. And anyway it's only a template and it is impossible to specify arguments from an extension.
2. DebugConfigurationProvider. The exact opposite situation: it is possible to specify all debug session settings, but it is impossible to export these settings to launch.json.
Separate `"rust-analyzer.newDebugConfig"` command looks better for me.
