internal: Add config to specifiy lru capacities for all queries
Might help figuring out what queries should be limited by LRU by default, as currently we only limit `parse`, `parse_macro_expansion` and `macro_expand`.
Add Cargo-style project discovery for Buck and Bazel Users
This feature requires the user to add a command that generates a `rust-project.json` from a set of files. Project discovery can be invoked in two ways:
1. At extension activation time, which includes the generated `rust-project.json` as part of the linkedProjects argument in `InitializeParams`.
2. Through a new command titled "rust-analyzer: Add current file to workspace", which makes use of a new, rust-analyzer-specific LSP request that adds the workspace without erasing any existing workspaces. Note that there is no mechanism to _remove_ workspaces other than "quit the rust-analyzer server".
Few notes:
- I think that the command-running functionality _could_ merit being placed into its own extension (and expose it via extension contribution points) to provide build-system idiomatic progress reporting and status handling, but I haven't (yet) made an extension that does this nor does Buck expose this sort of functionality.
- This approach would _just work_ for Bazel. I'll try and get the tool that's responsible for Buck integration open-sourced soon.
- On the testing side of things, I've used this in around my employer's Buck-powered monorepo and it's a nice experience. That being said, I can't think of an open-source repository where this can be tested in public, so you might need to trust me on this one.
I'd love to get feedback on:
- Naming of LSP extensions/new commands. I'm not too pleased with how "rust-analyzer: Add current file to workspace" is named, in that it's creating a _new_ workspace. I think that this command being added should be gated on `rust-analyzer.discoverProjectCommand` on being set, so I can add this in sequent commits.
- My Typescript. It's not particularly good.
- Suggestions on handling folders with _both_ Cargo and non-Cargo build systems and if I make activation a bit better.
(I previously tried to add this functionality entirely within rust-analyzer-the-LSP server itself, but matklad was right—an extension side approach is much, much easier.)

Beginning of MIR
This pull request introduces the initial implementation of MIR lowering and interpreting in Rust Analyzer.
The implementation of MIR has potential to bring several benefits:
- Executing a unit test without compiling it: This is my main goal. It can be useful for quickly testing code changes and print-debugging unit tests without the need for a full compilation (ideally in almost zero time, similar to languages like python and js). There is a probability that it goes nowhere, it might become slower than rustc, or it might need some unreasonable amount of memory, or we may fail to support a common pattern/function that make it unusable for most of the codes.
- Constant evaluation: MIR allows for easier and more correct constant evaluation, on par with rustc. If r-a wants to fully support the type system, it needs full const eval, which means arbitrary code execution, which needs MIR or something similar.
- Supporting more diagnostics: MIR can be used to detect errors, most famously borrow checker and lifetime errors, but also mutability errors and uninitialized variables, which can be difficult/impossible to detect in HIR.
- Lowering closures: With MIR we can find out closure capture modes, which is useful in detecting if a closure implements the `FnMut` or `Fn` traits, and calculating its size and data layout.
But the current PR implements no diagnostics and doesn't support closures. About const eval, I removed the old const eval code and it now uses the mir interpreter. Everything that is supported in stable rustc is either implemented or is super easy to implement. About interpreting unit tests, I added an experimental config, disabled by default, that shows a `pass` or `fail` on hover of unit tests (ideally it should be a button similar to `Run test` button, but I didn't figured out how to add them). Currently, no real world test works, due to missing features including closures, heap allocation, `dyn Trait` and ... so at this point it is only useful for me selecting what to implement next.
The implementation of MIR is based on the design of rustc, the data structures are almost copy paste (so it should be easy to migrate it to a possible future stable-mir), but the lowering and interpreting code is from me.
add openDocs command to context menu in VS Code extension
This adds the `openDocs` command to the VS Code context menu. I believe there are probably many user who are unaware of this command existing in the rust analyzer extension, and that this should enhance the discoverability of the command. Additionally, even if people are aware of this capability, it's helpful to have this in the context menu anyway; for example, one might forget the name of the command, or the keybinding they have assigned to it. I think that opening docs is a common enough action to warrant the extra line added to the context menu.
This makes a few other small changes as well. There are two minor style changes to increase style consistency. First, it changes the titles of the two commands that the rust analyzer extension will contribute to the context menu to title case. All standard VS Code commands that appear in the context menu are in title case. Second, it shortens the title of the `openDocs` command from `Open docs under cursor` to `Open Docs`. The implicit assumption in the standard VS Code context menu command titles is that the action applies to the symbol under the cursor: `Go to Definition`, `Find All References`, etc. Note that since these are changes to the command titles, rather than the command names themselves, these changes will not break any users' existing keybindings for these commands.
Second, this adds further restrictions to the `where` clauses of the two commands that the rust analyzer extension will contribute to the context menu, so that the two commands will appear in the context menu only when in a Rust project **and** within a Rust file. Say you have a Python or bash script inside your Rust project. Having these commands appear in the context menu when you right click a symbol in such a non-Rust file is extraneous and potentially confusing.
fix: Suppress extra indent after the end of field and function chains
(spurred on by <https://github.com/rust-lang/rust-analyzer/issues/4182#issuecomment-671275652>)
Caveat that this doesn't work for after tail expressions, although there shouldn't be anything after those anyways.
This also complicates when to reload the language configuration by nature of now always having a language configuration applicable.
Examples of indentation fixes:
```rs
fn main() {
println!("Hello!"); // < enter here!
// ... indents down here
fs::read_to_string("soup") // < enter here!
// ... still indents down here :(
.map(|_| ())
.map(|_| ()) // < enter here!
// ... still indents down here :D
.map_err(|_| ())
.unwrap(); // < enter here!
// ... indents down here :D
// ... and subsequent enters stay at the same indent
0.0f64
.to_radians()
.to_radians()
.to_radians() // force semi on a new line
; // < enter here!
// ... indents down here :D
}
fn tail_end() -> i32 {
0i32.wrapping_abs()
.wrapping_abs()
.wrapping_abs()
.wrapping_abs() // < enter here!
// ... still indents here 🤷
}
```
minor: Explicitly disable the rust-analyzer extension in untrusted workspaces
This is the default, but its always better to be explicit here + we can add a small note as to why.
Use ANSI control characters to display text decorations matching the
VScode terminal theme, and strip them out when providing text content
for rustc diagnostics.
This adds the small `anser` library to parse the control codes, and it
also supports HTML output so it should be fairly easy to switch to a
rendered HTML/webview implementation if desired.
Rename `checkOnSave` settings to `check`
Now that flychecks can be triggered without saving the setting name doesn't make that much sense anymore. This PR renames it to just `check`, but keeps `checkOnSave` as the enabling setting.
feat: add the ability to limit the number of threads launched by `main_loop`
## Motivation
`main_loop` defaults to launch as many threads as cpus in one machine. When developing on multi-core remote servers on multiple projects, this will lead to thousands of idle threads being created. This is very annoying when one wants check whether his program under developing is running correctly via `htop`.

## Contribution
This patch introduce the configuration option `rust-analyzer.numThreads` to set the desired thread number used by the main thread pool.
This should have no effects on the performance as not all threads are actually used.
<img width="1325" alt="image" src="https://user-images.githubusercontent.com/41831480/206656834-fe625c4c-b993-4771-8a82-7427c297fd41.png">
## Demonstration
The following is a snippet of `lunarvim` configuration using my own build.
```lua
vim.list_extend(lvim.lsp.automatic_configuration.skipped_servers, { "rust_analyzer" })
require("lvim.lsp.manager").setup("rust_analyzer", {
cmd = { "env", "RA_LOG=debug", "RA_LOG_FILE=/tmp/ra-test.log",
"/home/jlhu/Projects/rust-analyzer/target/debug/rust-analyzer",
},
init_options = {
numThreads = 4,
},
settings = {
cachePriming = {
numThreads = 8,
},
},
})
```
## Limitations
The `numThreads` can only be modified via `initializationOptions` in early initialisation because everything has to wait until the thread pool starts including the dynamic settings modification support.
The `numThreads` also does not reflect the end results of how many threads is actually created, because I have not yet tracked down everything that spawns threads.

Didn't add a test because I was not sure on how to add test for a specific configuration option, tried to look for the usages for other `AssistConfig` variants but couldn't find any in `tests`. If there is a way to test this, do point me towards it.
I tried to extract the formatting string as a common `template_string` and only have if-else for that, but it didn't compile :(
Also it seems these tests are failing:

Can you also point me to how to correct these 😅 ( I guess there is some command to automatically generate these? )
Implement invocation strategy config
Fixes https://github.com/rust-lang/rust-analyzer/issues/10793
This allows to change how we run build scripts (and `checkOnSave`), exposing two configs:
- `once`: run the specified command once in the project root (the working dir of the server)
- `per_workspace`: run the specified command per workspace in the corresponding workspace
This also applies to `checkOnSave` likewise, though `once_in_root` is useless there currently, due to https://github.com/rust-lang/cargo/issues/11007
VS Code problem matcher are restricted to be static "regexes". You can't
create a problem matcher dynamically, and you can't use custom code in
lieu of problem matcher.
This creates a problem for rust/cargo compiler errors. They use paths
relative to the root of the Cargo workspace, but VS Code doesn't
necessary know where that root is.
Luckily, there's a way out: our current problem matcher is defined like
this:
"fileLocation": [ "autoDetect", "${workspaceRoot}" ],
That means that relative pahts would be resoleved relative to workspace
root. VS Code allows to specify a command inside `${}`. So we can plug
custom logic there to fetch Cargo's workspace root!
And that's exactly what this PR is doing!
Add a new configuration settings to set env vars when running cargo, rustc, etc. commands: cargo.extraEnv and checkOnSave.extraEnv
It can be extremely useful to be able to set environment variables when rust-analyzer is running various cargo or rustc commands (such as `cargo check`, `cargo --print cfg` or `cargo metadata`): users may want to set custom `RUSTFLAGS`, change `PATH` to use a custom toolchain or set a different `CARGO_HOME`.
There is the existing `server.extraEnv` setting that allows env vars to be set when the rust-analyzer server is launched, but using this as the recommended mechanism to also configure cargo/rust has some drawbacks:
- It convolutes configuring the rust-analyzer server with configuring cargo/rustc (one may want to change the `PATH` for cargo/rustc without affecting the rust-analyzer server).
- The name `server.extraEnv` doesn't indicate that cargo/rustc will be affected but renaming it to `cargo.extraEnv` doesn't indicate that the rust-analyzer server would be affected.
- To make the setting useful, it needs to be dynamically reloaded without requiring that the entire extension is reloaded. It might be possible to do this, but it would require the client communicating to the server what the overwritten env vars were at first launch, which isn't easy to do.
This change adds two new configuration settings: `cargo.extraEnv` and `checkOnSave.extraEnv` that can be used to change the environment for the rust-analyzer server after launch (thus affecting any process that rust-analyzer invokes) and the `cargo check` command respectively. `cargo.extraEnv` supports dynamic changes by keeping track of the pre-change values of environment variables, thus it can undo changes made previously before applying the new configuration (and then requesting a workspace reload).
Allow configuration of annotation location.
I've added the ability to configure where lens annotations render relevant to the item they describe. Previously, these would render directly above the line the item is declared on. Now, there is the ability to render these annotations above the entire item (including doc comments, and attributes).
The names of the config options are up for debate, I did what seemed best to me but if anyone has better ideas let me know.
This is my first contribution so if I've missed anything please let me know.
Here's a preview of what the new option looks like:

Remove the toggleInlayHints command from VSCode
Inlay hints are no longer something specifc to r-a as it has been upstreamed into the LSP, we don't have a reason to give the config for this feature special treatment in regards to toggling. There are plenty of other options out there in the VSCode marketplace to create toggle commands/hotkeys for configurations in general which I believe we should nudge people towards instead.

Move empty diagnostics workaround back into the server

Remove auto-config patching from the VSCode client
This was introduced 4 months ago when we drastically changed the config keys. I'd like to remove this given I always felt uneasy doing edits to a users config from within r-a, and by now most if not all users should've swapped to a new enough version of r-a that should've updated their configs.
The extension will continue to work fine even with the outdated keys afterwards since we still do patching server side as well, and that one we'll have to support for quite some more time (if not until a proper 1.0 release where I assume we can allow ourselves some more user facing breakage)
(There also might've been a small bug in here that prevented users with certain outdated keys to prevent them from enabling certain keys for some reason)
chore: remove unused `currentExtensionIsNightly()` in `config.ts`
I was debugging an unrelated issue in rust-analyzer, but came across this unused code and figured that it's fine to send a fully red PR :)
This PR will fix some typos detected by [typos].
There are also some other typos in the function names, variable names, and file
names, which I leave as they are. I'm more certain that typos in comments
should be fixed.
[typos]: https://github.com/crate-ci/typos
While VSCode [uses it's own implementation for URIs](https://github.com/microsoft/vscode-uri)
which notably doesn't have any limits of URI size, the renderer itself
relies on Web platform engine, that limits the length of the URLs and
bails out when the attribute length of an `href` inside `a` tag is too
long.
Command URIs have a form of `command:command-name?arguments`, where
`arguments` is a percent-encoded array of data we want to pass along to
the command function. For "Show References" this is a list of all file
URIs with locations of every reference, and it can get quite long.
This PR introduces another intermediary `linkToCommand` command. When
we render a command link, a reference to a command with all its arguments
is stored in a map, and instead a `linkToCommand` link is rendered
with the key to that map.
For now the map is cleaned up periodically (I've set it to every
10 minutes). In general case we'll probably need to introduce TTLs or
flags to denote ephemeral links (like these in hover popups) and
persistent links and clean those separately. But for now simply keeping
the last few links in the map should be good enough. Likewise, we could
add code to remove a target command from the map after the link is
clicked, but assuming most links in hover sheets won't be clicked anyway
this code won't change the overall memory use much.
Closes#9926
Per [bjorn3][https://github.com/bjorn3] suggestion resolves cases where
an early return is moved to a separate line due to line width formatting.
This setting changes
```
if (a very long condition) return;
```
to
```
if (a very long
condition) {
return;
}
```
while keeping
```
if (short) return;
```
as is.
In pathological cases this may cause `npm run fix` not to fix formatting
in one go and may require running it twice.
[Prettier][1] is an up-to date code formatter for JavaScript ecosystem.
For settings we rely on [EditorConfig][2] for things like tab style and
size (with added bonus that the code editor with an EditorConfig plugin
does some automated code formatting on file save for you). Unfortunately,
Prettier's Glob handling isn't great:
1. `*.{ts,js,json}` has no effect
2. Similarly, in a list of globs `*.ts,*.js,*.json` only the first glob
has an effect, the rest are ignored.
That's why the file looks the way it does.
The only other setting we change is line width. [Lukas][3] suggested we
use 100 instead of 80, because that's what Rustfmt is using.

feat: Support variable substitution in VSCode settings
Currently support a subset of [variables provided by VSCode](https://code.visualstudio.com/docs/editor/variables-reference) in `server.extraEnv` section of Rust-Analyzer settings:
* `workspaceFolder`
* `workspaceFolderBasename`
* `cwd`
* `execPath`
* `pathSeparator`
Also, this PR adds support for general environment variables resolution. You can declare environment variables and reference them from other variables like this:
```JSON
"rust-analyzer.server.extraEnv": {
"RUSTFLAGS": "-L${env:OPEN_XR_SDK_PATH}",
"OPEN_XR_SDK_PATH": "${workspaceFolder}\\..\\OpenXR-SDK\\build\\src\\loader\\Release"
},
```
The order of variable declaration doesn't matter, you can reference variables before defining them. If the variable is not present in `extraEnv` section, VSCode will search for them in your environment. Missing variables will be replaced with empty string. Circular references won't be resolved and will be passed to rust-analyzer server process as is.
Closes#9626, but doesn't address use cases where people want to use values provided by `rustc` or `cargo`, such as `${targetTriple}` proposal #11649
First, we go through every environment variable key and record all cases
where there are reference to other variables / dependencies.
We track two sets of variables - resolved and yet-to-be-resolved.
We pass over a list of variables over and over again and when all
variable's dependencies were resolved during previous passes we perform
a replacement for that variable, too.
Over time the size of `toResolve` set should go down to zero, however
circular dependencies may prevent that. We track the size of `toResolve`
between iterations to avoid infinite looping.
At the end we produce an object of the same size and shape as
the original, but with the values replace with resolved versions.
Config revamp
Fixes https://github.com/rust-lang/rust-analyzer/issues/11790
Fixes https://github.com/rust-lang/rust-analyzer/issues/12115
This PR changes a lot of config names, and a few ones are being merged or split apart. The reason for this is that our configuration names currently are rather inconsistent and some where poorly chosen in regards to extensability. This PR plans to fix that.
We still allow the old config names by patching them to the new ones before deserializing to keep backwards compatability with other clients (the VSCode client will auto update the config) but ideally we will get rid of that layer in the future.

feat: allow customizing the command for running build scripts

10802: Allow clients to configure the global workspace search limit r=Veykril a=knutwalker
Playing around with [helix](https://helix-editor.com) I realized that the global worksapce symbol search works different compared to vs-code.
Helix requires all possible symbols in one query and does no subsequent refinement searched.
This PR adds a configuration option to override the default search limit with the default being the currently hardocded value.
Helix users can increment this limit for their instance with a config like
```toml
[[language]]
name = "rust"
language-server = { command = "rust-analyzer" }
[language.config]
workspace = { symbol = { search = { limit = 65536 }}}
```
Other editors are not affected by this change.

- [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!(),
};
}
```

10688: internal: Type-check TS on CI and also turn off the strict setting `useUnknownInCatchVariables` r=lnicola a=ChayimFriedman2
We don't follow it and I found that turning it on will have little benefit.
I'm not sure if we should also type-check when building in launch.json.
