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.
Here is a list of the changes:
These are simple renames `old_name | alias1 | alias2 ... -> new_name` (the vscode client will fix these up automagically):
```
assist_allowMergingIntoGlobImports -> imports_merge_glob
assist_exprFillDefault -> assist_expressionFillDefault
assist_importEnforceGranularity -> imports_granularity_enforce
assist_importGranularity | assist_importMergeBehavior | assist_importMergeBehaviour -> imports_granularity_group
assist_importGroup -> imports_group_enable
assist_importPrefix -> imports_prefix
cache_warmup -> primeCaches_enable
cargo_loadOutDirsFromCheck -> cargo_buildScripts_enable
cargo_runBuildScripts | cargo_runBuildScriptsCommand -> cargo_runBuildScripts_overrideCommand
cargo_useRustcWrapperForBuildScripts -> cargo_runBuildScripts_useRustcWrapper
completion_snippets -> completion_snippets_custom
diagnostics_enableExperimental -> diagnostics_experimental_enable
experimental_procAttrMacros -> procMacro_attributes_enable
highlighting_strings -> semanticHighlighting_strings_enable
highlightRelated_breakPoints -> semanticHighlighting_breakPoints_enable
highlightRelated_exitPoints -> semanticHighlighting_exitPoints_enable
highlightRelated_yieldPoints -> semanticHighlighting_yieldPoints_enable
highlightRelated_references -> semanticHighlighting_references_enable

hoverActions_debug -> hoverActions_debug_enable
hoverActions_enable -> hoverActions_enable_enable
hoverActions_gotoTypeDef -> hoverActions_gotoTypeDef_enable
hoverActions_implementations -> hoverActions_implementations_enable
hoverActions_references -> hoverActions_references_enable
hoverActions_run -> hoverActions_run_enable
inlayHints_chainingHints -> inlayHints_chainingHints_enable

inlayHints_typeHints -> inlayHints_typeHints_enable
lruCapacity -> lru_capacity
runnables_cargoExtraArgs -> runnables_extraArgs
runnables_overrideCargo -> runnables_command
rustcSource -> rustc_source
rustfmt_enableRangeFormatting -> rustfmt_rangeFormatting_enable
```
These are configs that have been merged or split apart, which have to be manually updated by the user:
```
callInfo_full -> signatureInfo_detail, signatureInfo_documentation_enable
cargo_allFeatures, cargo_features -> cargo_features
checkOnSave_allFeatures, checkOnSave_features -> checkOnSave_features
completion_addCallArgumentSnippets completion_addCallParenthesis -> completion_callable_snippets
```
feat: allow customizing the command for running build scripts
I have tested this locally and it fixed#9201 with some small changes on the compiler side with suggestions from https://github.com/rust-analyzer/rust-analyzer/issues/9201#issuecomment-1019554086.
I have also added an environment variable `IS_RA_BUILDSCRIPT_CHECK` for crates to detect that it is a check for buildscripts, and allows defaulting to bogus values for expected environment variables.
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.

Assuming ID=linux in isNixOs by default. You can get away with
default "", but why do that if there's a default value in spec?)
Also removed toLowerCase — it really shouldn't be needed.
Fixes#11709
11445: Upstream inlay hints r=lnicola a=lnicola
Closes https://github.com/rust-analyzer/rust-analyzer/issues/2797
Closes https://github.com/rust-analyzer/rust-analyzer/issues/3394 (since now resolve the hints for the range given only, not for the whole document. We don't actually resolve anything due to [hard requirement](https://github.com/rust-analyzer/rust-analyzer/pull/11445#issuecomment-1035227434) on label being immutable. Any further heavy actions could go to the `resolve` method that's now available via the official Code API for hints)
Based on `@SomeoneToIgnore's` branch, with a couple of updates:
- I squashed, more or less successfully, the commits on that branch
- downloading the `.d.ts` no longer works, but you can get it manually from https://raw.githubusercontent.com/microsoft/vscode/release/1.64/src/vscode-dts/vscode.proposed.inlayHints.d.ts
- you might need to pass `--enable-proposed-api matklad.rust-analyzer`
- if I'm reading the definition right, `InlayHintKind` needs to be serialized as a number, not string
- this doesn't work anyway -- the client-side gets the hints, but they don't display

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!(),
};
}
```

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.
