- prevent `pat` from matching before `path` in metavariable types
- reduce the precedence of math operators so that assignment operators match correctly
- remove comment scope from ignored params
- underscores will automatically receive variable/param scope
- add raw ID syntax to modules, functions, and variables
6251: Semantic Highlight: Add Callable modifier for variables r=matklad a=GrayJack
This PR added the `HighlightModifier::Callable` variant and assigned it to variables and parameters that are fn pointers, closures and implements FnOnce trait.
This allows to colorize these variables/parameters when used in call expression.
6310: Rewrite algo::diff to support insertion and deletion r=matklad a=Veykril
This in turn also makes `algo::diff` generate finer diffs(maybe even minimal diffs?) as insertions and deletions aren't always represented as as replacements of parent nodes now.
Required for #6287 to go on.

6137: add a new TextMate grammar r=matklad a=dustypomerleau
Thanks to everyone working hard on Rust Analyzer - my impression is that it's quickly becoming the community default.
I think it would be helpful to have a more robust TextMate grammar to fall back on, for those who wish to disable semantic highlighting for any reason. It should allow theming of punctuation, and provide scopes for all tokens on the page. This can be done at zero cost to those who enable semantic highlighting, as the TextMate scopes will be invisible to those users.
I can see a couple ways of accomplishing this:
1. Ship a new grammar by merging this PR.
1. Ship no TextMate grammar at all (like the [Rust](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust) extension), and allow users to install a separate extension that provides the grammar of their choice (I have released this one as [Rust Syntax](https://marketplace.visualstudio.com/items?itemName=dustypomerleau.rust-syntax)). If no grammar were installed, they would simply fall back to the default grammar provided by their editor. In the case of VS Code, the default grammar already matches what is currently being shipped, so users who choose not to override it would see no difference.
I have tried to choose sensible default scopes, in the hopes that a wider variety of themes would work out of the box with Rust, even if those themes do not yet supply scopes for semantic highlighting. There is definitely some interest in using this grammar with Rust Analyzer, as this was the very first issue after the syntax extension was shipped: https://github.com/dustypomerleau/rust-syntax/issues/1.
I considered simply using an alternative grammar alongside Rust Analyzer, but this doesn't seem possible. When RA starts, any existing grammar/extension is overridden, and I haven't been able to find a workaround.

Currently a method only has defaultness if it is a provided trait
method, but this will change when specialisation is available and may
need to become a concept known to hir.
I opted to go for a 'fewest changes' approach given specialisation is
still under development.
* Chalk very recently (like an hour ago) merged a fix that prevents rust analyzer from panicking. This allows it to be usable again for code that hits those situations. See #6134, #6145, Probably #6120
The previous version would have interpreted an empty token as
an abort of the dialog and would have not properly cleared the token.
This is now fixed by checking for `undefined` for a an abort and
by setting the token to `undefined` in order to clear it.
This change allows to use a authorization token provided by Github in
order to fetch metadata for a RA release. Using an authorization token
prevents to get rate-limited in environments where lots of RA users use
a shared client IP (e.g. behind a company NAT).
The auth token is stored in `ExtensionContext.globalState`.
As far as I could observe through testing with a local WSL2 environment
that state is synced between an extension installed locally and a remote
version.
The change provides no explicit command to query for an auth token.
However in case a download fails it will provide a retry option as well
as an option to enter the auth token. This should be more discoverable
for most users.
Closes#3688
5985: Make MergeBehaviour configurable r=jonas-schievink a=Veykril
This should make the newly implemented `MergeBehaviour` for import insertion configurable as roughly outlined in https://github.com/rust-analyzer/rust-analyzer/pull/5935#issuecomment-685834257. For the config name and the like I just picked what came to mind so that might be up for bikeshedding.

5682: Add an option to disable diagnostics r=matklad a=popzxc
As far as I know, currently it's not possible to disable a selected type of diagnostics provided by `rust-analyzer`.
This causes an inconvenient situation with a false-positive warnings: you either have to disable all the diagnostics, or you have to ignore these warnings.
There are some open issues related to this problem, e.g.: https://github.com/rust-analyzer/rust-analyzer/issues/5412, https://github.com/rust-analyzer/rust-analyzer/issues/5502
This PR attempts to make it possible to selectively disable some diagnostics on per-project basis.

Generate properly formatted whitespace when adding impl items - with an empty line between items and removing extra whitespace that often appears at the end.

No we return ContentModified during the workspace loading. This signifies the language
client to retry the operation (i.e. the client will
continue polling the server while it returns ContentModified).
I believe that there might be cases of overly big projects where the backoff
logic we have setup in `sendRequestWithRetry` (which we use for inlay hints)
might bail too early (currently the largest retry standby time is 10 seconds).
However, I've tried on one of my project with 500+ dependencies and it is still enough.

Fixes#4551
`vscode.window.visibleTextEditors` only contains editors whose contents are being displayed at the moment, so the previous logic only worked if the other file for which a snippetTextEdit is being received was visible in a separate split.
I feel that this is a hacky approach, so feel free to reject it for something nicer :)

Override miniz_oxide to build it with optimizations
Building this crate with optimizations decreases the gzipping
part of `cargo xtask dist` from `30-40s` down to `3s`,
the overhead for `rustc` to apply optimizations is miserable on this background
5202: Runnable env r=matklad a=vsrs
This PR adds on option to specify (in the settings.json) environment variables passed to the runnable.
The simplest way for all runnables in a bunch:
```jsonc
"rust-analyzer.runnableEnv": {
"RUN_SLOW_TESTS": "1"
}
```
Or it is possible to specify vars more granularly:
```jsonc
"rust-analyzer.runnableEnv": [
{
// "mask": null, // null mask means that this rule will be applied for all runnables
env: {
"APP_ID": "1",
"APP_DATA": "asdf"
}
},
{
"mask": "test_name",
"env": {
"APP_ID": "2", // overwrites only APP_ID
}
}
]
```
You can use any valid RegExp as a mask. Also note that a full runnable name is something like *run bin_or_example_name*, *test some::mod::test_name* or *test-mod some::mod*, so it is possible to distinguish binaries, single tests, and test modules with this masks: `"^run"`, `"^test "` (the trailing space matters!), and `"^test-mod"` respectively.

5089: Disable auto-complete on comments r=matklad a=BGluth
Resolves#4907 by disabling any auto-completion on comments.
As flodiebold [pointed out](https://github.com/rust-analyzer/rust-analyzer/issues/4907#issuecomment-648439979), in the future we may want to support some form of auto-completion within doc comments, but for now it was suggested to just disable auto-completion on them entirely.
The implementation involves adding a new field `is_comment` to `CompletionContext` and checking if the immediate token we auto-completed on is a comment. I couldn't see a case where we need to check any of the ancestors, but let me know if this is not sufficient. I also wasn't sure if it was necessary to add a new field to this struct, but I decided it's probably the best option if we want to potentially do auto-completion on doc comments in the future.
Finally, the three tests I added should I think ideally not filter results by `CompletionKind::Keyword`, but if I want to get unfiltered results, I need access to a non-public function [get_all_completion_items](9a4d02faf9/crates/ra_ide/src/completion/test_utils.rs (L32-L39)) which I don't know if I should make public just for this.

5184: Always install required nightly extension if current one is not nightly r=matklad a=Veetaha
This is weird, but having switched back to stable by uninstalling the extension appears that vscode doesn't destroy the `PersistentState` and thus changing to `nightly` channel doesn't work because the last check for nightly extension was less than 1 hour ago. The simple solution is to skip this check if we know that the current extension version is not nightly.

5101: Add expect -- a light-weight alternative to insta r=matklad a=matklad
This PR implements a small snapshot-testing library. Snapshot updating is done by setting an env var, or by using editor feature (which runs a test with env-var set).
Here's workflow for updating a failing test:
![expect](https://user-images.githubusercontent.com/1711539/85926956-28afa080-b8a3-11ea-9260-c6d0d8914d0b.gif)
Here's workflow for adding a new test:
![expect-fresh](https://user-images.githubusercontent.com/1711539/85926961-306f4500-b8a3-11ea-9369-f2373e327a3f.gif)
Note that colorized diffs are not implemented in this PR, but should be easy to add (we already use them in test_utils).
Main differences from insta (which is essential for rust-analyzer development, thanks @mitsuhiko!):
* self-updating tests, no need for a separate tool
* fewer features (only inline snapshots, no redactions)
* fewer deps (no yaml, no persistence)
* tighter integration with editor
* first-class snapshot object, which can be used to write test functions (as opposed to testing macros)
* trivial to tweak for rust-analyzer needs, by virtue of being a workspace member.
I think eventually we should converge to a single snapshot testing library, but I am not sure that `expect` is exactly right, so I suggest rolling with both insta and expect for some time (if folks agree that expect might be better in the first place!).
# Editor Integration Implementation
The thing I am most excited about is the ability to update a specific snapshot from the editor. I want this to be available to other snapshot-testing libraries (cc @mitsuhiko, @aaronabramov), so I want to document how this works.
The ideal UI here would be a code action (💡). Unfortunately, it seems like it is impossible to implement without some kind of persistence (if you save test failures into some kind of a database, like insta does, than you can read the database from the editor plugin). Note that it is possible to highlight error by outputing error message in rustc's format. Unfortunately, one can't use the same trick to implement a quick fix.
For this reason, expect makes use of another rust-analyzer feature -- ability to run a single test at the cursor position. This does need some expect-specific code in rust-analyzer unfortunately. Specifically, if rust-analyzer notices that the cursor is on `expect!` macro, it adds a special flag to runnable's JSON. However, given #5017 it is possible to approximate this well-enough without rust-analyzer integration. Specifically, an extension can register a special runner which checks (using regexes) if rust-anlyzer runnable covers text with specific macro invocation and do special magic in that case.

5025: Don't mess with messy temp dir and just download into extension dir r=matklad a=Veetaha
Temp dirs are messy. Dealing with them requires handling quite a bunch of
edge cases. As proposed by lnicola this seems better to just put the temp files
in the extension dir and not care much about suddenly leaving garbage.
Instead we get shorter and less platform-caveat-y code.
We will also assume users don't try to issue a download in different vscode windows simultaneously.
