3053: Feature: downloading lsp server from GitHub r=matklad a=Veetaha
This is currently very WIP, I may need to change this and that, add "download language server command", logging stuff (for future bug reports), etc., but it already works.
Also didn't test this on windows yet and mac (don't have the latter)
The quirks:
* Downloaded binary doesn't have executable permissions by default, that's why we ~~`chmod 111`~~ (**[UPD]** `chmod 755` as per @lnicola [suggestion](https://github.com/rust-analyzer/rust-analyzer/pull/3053#discussion_r376694456)) for it.
* To remove installed binary run `rm /${HOME}/.config/Code/User/globalStorage/matklad.rust-analyzer/ra_lsp_server-linux`, ~~note that `-f` flag is necessary, because of `111` permissions (I think this should be changed)~~ (**[UPD]** --force is no longer needed due to 755 permissions).
I also tried to keep things simple and not to use too many dependencies, all the ones added have 0 dependencies, (`ts-not-nil` is my personal npm package, that imitates `unwrap()` in TypeScript)
**[UPD]** I reduced throttle latency of progress indicator to 200ms for smoother UX
// TODO:
- [x] ~~Add `Rust Analyzer: Download latest language server` vscode command.~~ **[UPD]**: having reviewed the code and estimated available options I concluded that this feature requires too many code changes, I'd like to extract this into a separate PR after we merge this one.
- [x] Add some logging for future debugging
- [x] ~~Gracefully handle the case when language server is not available (e.g. no internet connection, user explicitly rejected the download, etc.)~~ **[UPD]** Decided to postpone better implementation of graceful degradation logic as per [conversation](https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0/topic/Deployment.20and.20installation/near/187758550).
Demo (**[UPD]** this is a bit outdated, but still mainly reflects the feature):

2979: vscode: now we are actually using tslib r=matklad a=Veetaha
We had an incorrect setup where `tslib` was in `devDependencies`.
FYI:
tslib is a runtime dependency, it contains functions that are used by transpiled JavaScript in order not to inline them in each file.
For example:
```ts
// foo.ts (source code)
import * as foo from "foo";
// ---------------------------
// foo.js (compiled output)
"use strict";
var __importStar = (this && this.__importStar) || function (mod) {
if (mod && mod.__esModule) return mod;
var result = {};
if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
result["default"] = mod;
return result;
};
Object.defineProperty(exports, "__esModule", { value: true });
const foo = __importStar(require("foo"));
```
As you see, `tsc` generated that `__importStar` helper function in compiled output. And it generates it per each file if you don't enable `"importHelpers": true`. Now with `importHelpers` enabled we get the following picture:
```ts
// foo.ts (source code)
import * as foo from "foo";
// ---------------------------
// foo.js (compiled output)
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const tslib_1 = require("tslib");
const foo = tslib_1.__importStar(require("foo"));
```
It saves some bundle size, but I am not entirely sure wheter we want that. Discussions are welcome!

2964: Improve responsiveness of the cargo check status label r=matklad a=lnicola
This is still not ideal because the label displays the crate that was just checked, not the one that's currently being checked. But it should give the impression of being faster.

2963: Emacs fixes r=matklad a=flodiebold
- use provided environment for runnables (finally set `RUST_BACKTRACE`)
- implement `selectAndApplySourceChange` so auto-import works 🙂

2967: Disable optimizations for some build-time crates r=matklad a=lnicola
This speeds up a release build on my laptop from 4m 13s to 3m 33s. It's a bit disappointing, but we don't get perfect parallelism during the build. The non-RA dependencies finish building around 72s as opposed to 112s.

2061: Theme loading and "editor.tokenColorCustomizations" support. r=matklad a=seivan
Fixes: [Issue#1294](https://github.com/rust-analyzer/rust-analyzer/issues/1294#issuecomment-497450325)
TODO:
- [x] Load themes
- [x] Load existing `ralsp`-prefixed overrides from `"workbench.colorCustomizations"`.
- [x] Load overrides from `"editor.tokenColorCustomizations.textMateRules"`.
- [x] Use RA tags to load `vscode.DecorationRenderOptions` (colors) from theme & overrides.
- [x] Map RA tags to common TextMate scopes before loading colors.
- [x] Add default scope mappings in extension.
- [x] Cache mappings between settings updates.
- [x] Add scope mapping configuration manifest in `package.json`
- [x] Load configurable scope mappings from settings.
- [x] Load JSON Scheme for text mate scope rules in settings.
- [x] Update [Readme](https://github.com/seivan/rust-analyzer/blob/feature/themes/docs/user/README.md#settings).
Borrowed the theme loading (`scopes.ts`) from `Tree Sitter` with some modifications to reading `"editor.tokenColorCustomizations"` for merging with loaded themes and had to remove the async portions to be able to load it from settings updates.
~Just a PoC and an idea I toyed around with a lot of room for improvement.~
For starters, certain keywords aren't part of the standard TextMate grammar, so it still reads colors from the `ralsp` prefixed values in `"workbench.colorCustomizations"`.
But I think there's more value making the extension work with existing themes by maping some of the decoration tags to existing key or keys.

These will merge with the default ones coming with the extension, so you don't have to implement all of them and works well with overrides defined in settings.
```jsonc
"editor.tokenColorCustomizations": {
"textMateRules": [
{
"scope": "keyword",
"settings": {
"fontStyle": "bold",
}
},
]
},
```
Edit: The idea is to work with 90% of the themes out there by working within existing scopes available that are generally styled. It's not to say I want to erase the custom Rust scopes - those should still remain and eventually worked into a custom grammar bundle for Rust specific themes that target those, I just want to make it work with generic themes offered on the market place for now.
A custom grammar bundle and themes for Rust specific scopes is out of... scope for this PR.
We'll make another round to tackle those issues.
