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!

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.

1984: Bump rollup and vsce r=matklad a=kjeremy
I got sick of the vsce warning on install and noticed that rollup was also out of date.
Co-authored-by: kjeremy <kjeremy@gmail.com>
The old `vscode` package is outdated and it is recommened to switch to
these two new packages. This also solves a problem of a missing `.d.ts`
for `vscode` in Nixos.
This is actually much faster than I expected; it takes about 13 seconds
to download VS Code and run the unit tests. This means the VS Code tests
are still significantly faster than the Rust ones.
If this ends up being unreliable we can always remove it later or move
it to a separate optional job.
We also need to ignore the `.vscode-test` directory when running
`prettier` or it will get upset about some temporary JSON files VS Code
creates.
As promised in #1439 this is an initial attempt at unit testing the
VSCode extension. There are two separate parts to this: getting the test
framework working and unit testing the code in #1439.
The test framework nearly intact from the VSCode extension generator.
The main thing missing was `test/index.ts` which acts as an entry point
for Mocha. This was simply copied back in. I also needed to open the
test VSCode instance inside a workspace as our file URI generation
depends on a workspace being open.
There are two ways to run the test framework:
1. Opening the extension's source in VSCode, pressing F5 and selecting
the "Extensions Test" debug target.
2. Closing all copies of VSCode and running `npm test`. This is started
from the command line but actually opens a temporary VSCode window to
host the tests.
This doesn't attempt to wire this up to CI. That requires running a
headless X11 server which is a bit daunting. I'll assess the difficulty
of that in a follow-up branch. This PR is at least helpful for local
development without having to induce errors on a Rust project.
For the actual tests this uses snapshots of `rustc` output from a real
Rust project captured from the command line. Except for extracting the
`message` object and reformatting they're copied verbatim into fixture
JSON files.
Only four different types of diagnostics are tested but they represent
the main combinations of code actions and related information possible.
They can be considered the happy path tests; as we encounter
corner-cases we can introduce new tests fixtures.
Very simple approach: For each identifier, set the hash of the range
where it's defined as its 'id' and use it in the VSCode extension to
generate unique colors.
Thus, the generated colors are per-file. They are also quite fragile,
and I'm not entirely sure why. Looks like we need to make sure the
same ranges aren't overwritten by a later request?
