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
This only touches on the diagnostics in one place instead of multiple as was previously done, since all published diagnostics will go through this code path anyways.
Closes https://github.com/rust-lang/rust-analyzer/issues/13130
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The extension will continue to work fine even with the outdated keys afterwards since we still do patching server side as well, and that one we'll have to support for quite some more time (if not until a proper 1.0 release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(There also might've been a small bug in here that prevented users with certain outdated keys to prevent them from enabling certain keys for some reason)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.

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.
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
