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:
Here's workflow for adding a new test:
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.

5120: Add a simple SSR subcommand to the rust-analyzer command line binary r=davidlattimore a=davidlattimore
Is adding the dependency on ra_ide_db OK? It's needed for the call to `db.local_roots()`
Co-authored-by: David Lattimore <dml@google.com>
There are two reasons why we don't want a generic ra_progress crate
just yet:
*First*, it introduces a common interface between separate components,
and that is usually undesirable (b/c components start to fit the
interface, rather than doing what makes most sense for each particular
component).
*Second*, it introduces a separate async channel for progress, which
makes it harder to correlate progress reports with the work done. Ie,
when we see 100% progress, it's not blindly obvious that the work has
actually finished, we might have some pending messages still.

4937: Allow overriding rust-analyzer display version r=matklad a=oxalica
The build script invokes `git` for version information which is displayed when rust-analyzer is called with `--version`. But in build environment without `git` or when the source code is not a git repo, there's no way to manually specify the version information.
This patch respects environment variable ~`REV`~ `RUST_ANALYZER_REV` in compile time for overriding.

4916: Warnings as hint or info r=matklad a=GabbeV
Fixes#4229
This PR is my second attempt at providing a solution to the above issue. My last PR(#4721) had to be rolled back(#4862) due to it overriding behavior many users expected. This PR solves a broader problem while trying to minimize surprises for the users.
### Problem description
The underlying problem this PR tries to solve is the mismatch between [Rustc lint levels](https://doc.rust-lang.org/rustc/lints/levels.html) and [LSP diagnostic severity](https://microsoft.github.io/language-server-protocol/specification#diagnostic). Rustc currently doesn't have a lint level less severe than warning forcing the user to disable warnings if they think they get to noisy. LSP however provides two severitys below warning, information and hint. This allows editors like VSCode to provide more fine grained control over how prominently to show different diagnostics.
Info severity shows a blue squiggly underline in code and can be filtered separately from errors and warnings in the problems panel.
Hint severity doesn't show up in the problems panel at all and only show three dots under the affected code or just faded text if the diagnostic also has the unnecessary tag.
### Solution
The solution provided by this PR allows the user to configure lists of of warnings to report as info severity and hint severity respectively. I purposefully only convert warnings and not errors as i believe it's a good idea to have the editor show the same severity as the compiler as much as possible.
### Open questions
#### Discoverability
How do we teach this to new and existing users? Should a section be added to the user manual? If so where and what should it say?
#### Defaults
Other languages such as TypeScript report unused code as hint by default. Should rust-analyzer similarly report some problems as hint/info by default?

Anchoring to the SourceRoot wont' work if the path is absolute:
#[path = "/tmp/foo.rs"]
mod foo;
Anchoring to a file will.
However, we *should* anchor, instead of just producing an abs path.
I can imagine a situation where, for example, rust-analyzer processes
crates from different machines (or, for example, from in-memory git
branch), where the same absolute path in different crates might refer
to different files in the end!
4784: Change management of test cfg to better support json projects r=Nashenas88 a=Nashenas88
This helps support json projects where they can decide whether to add the `test` cfg or not. One alternative is to add support for marking json project crates as a sysroot crate, and adding logic to remove the `test` cfg in those cases. In my opinion, that option gives less flexibility to json projects and leads to more functionality that needs to be maintained.

This should fix https://github.com/rust-analyzer/rust-analyzer/issues/4515.
Note that this does introduce a change in behavior: We now always refer to items defined in external crates using paths through the external crate. Previously we could also use a local path (if for example the extern crate was reexported locally), as seen in the changed test. If that is undesired I can fix that, but the test didn't say why the previous behavior would be preferable.

Eventually, we should support "just open random rust file" use case,
we don't really do this now, so let's avoid spending time on it until
we fix it properly.
As per matklad, we now pass the responsibility for finding the binary to the frontend.
Also, added caching for finding the binary path to reduce
the amount of filesystem interactions.
The line separator is moved below the function signature to split
regions between the docs. This is very similar to how IntelliJ
displays tooltips. Adding an additional separator between the module
name and function signature currently has rendering issues.

4448: Generate configuration for launch.json r=vsrs a=vsrs
This PR adds two new commands: `"rust-analyzer.debug"` and `"rust-analyzer.newDebugConfig"`. The former is a supplement to the existing `"rust-analyzer.run"` command and works the same way: asks for a runnable and starts new debug session. The latter allows adding a new configuration to **launch.json** (or to update an existing one).
If the new option `"rust-analyzer.debug.useLaunchJson"` is set to true then `"rust-analyzer.debug"` and Debug Lens will first look for existing debug configuration in **launch.json**. That is, it has become possible to specify startup arguments, env variables, etc.
`"rust-analyzer.debug.useLaunchJson"` is false by default, but it might be worth making true the default value. Personally I prefer true, but I'm not sure if it is good for all value.
----
I think that this PR also solves https://github.com/rust-analyzer/rust-analyzer/issues/3441.
Both methods to update launch.json mentioned in the issue do not work:
1. Menu. It is only possible to add a launch.json configuration template via a debug adapter. And anyway it's only a template and it is impossible to specify arguments from an extension.
2. DebugConfigurationProvider. The exact opposite situation: it is possible to specify all debug session settings, but it is impossible to export these settings to launch.json.
Separate `"rust-analyzer.newDebugConfig"` command looks better for me.

4397: Textmate cooperation r=matklad a=georgewfraser
This PR tweaks the fallback TextMate scopes to make them more consistent with the existing grammar and other languages, and edits the builtin TextMate grammar to align with semantic coloring. Before is on the left, after is on the right:
<img width="855" alt="Screen Shot 2020-05-10 at 1 45 51 PM" src="https://user-images.githubusercontent.com/1369240/81512320-a8be7e80-92d4-11ea-8940-2c03f6769015.png">
**Use keyword.other for regular keywords instead of keyword**. This is a really peculiar quirk of TextMate conventions, but virtually *all* TextMate grammars use `keyword.other` (colored blue in VSCode Dark+) for regular keywords and `keyword.control` (colored purple in VSCode Dark+) for control keywords. The TextMate scope `keyword` is colored like control keywords, not regular keywords. It may seem strange that the `keyword` scope is not the right fallback for the `keyword` semantic token, but TextMate has a long and weird history. Note how keywords change from purple back to blue (what they were before semantic coloring was added):
**(1) Use punctuation.section.embedded for format specifiers**. This aligns with how Typescript colors formatting directives:
<img width="238" alt="Screen Shot 2020-05-09 at 10 54 01 AM" src="https://user-images.githubusercontent.com/1369240/81481258-93b5f280-91e3-11ea-99c2-c6d258c5bcad.png">
**(2) Consistently use `entity.name.type.*` scopes for type names**. Avoid using `entity.name.*` which gets colored like a keyword.
**(3) Use Property instead of Member for fields**. Property and Member are very similar, but if you look at the TextMate fallback scopes, it's clear that Member is intended for function-like-things (methods?) and Property is intended for variable-like-things.
**(4) Color `for` as a regular keyword when it's part of `impl Trait for Struct`**.
**(5) Use `variable.other.constant` for constants instead of `entity.name.constant`**. In the latest VSCode insiders, variable.other.constant has a subtly different color that differentiates constants from ordinary variables. It looks close to the green of types but it's not the same---it's a new color recently added to take advantage of semantic coloring.
I also made some minor changes that make the TextMate scopes better match the semantic scopes. The effect of this for the user is you observe less of a change when semantic coloring "activates". You can see the changes I made relative to the built-in TextMate grammar here:

The change in this PR simply renames this setting from `workspaceLoaded` to
`progress` to better describe what it actually controls. At the moment,
the only type of progress message that is controlled by this setting is
the initial load messages, but in theory other messages could also be
controlled by this setting.
Reviewer notes:
* If we didn't like the idea of causing minor breaking to user's config, we could keep the setting name as `workspaceLoaded`

4133: main: eagerly prime goto-definition caches r=matklad a=BurntSushi
This commit eagerly primes the caches used by goto-definition by
submitting a "phantom" goto-definition request. This is perhaps a bit
circuitous, but it does actually get the job done. The result of this
change is that once RA is finished its initial loading of a project,
goto-definition requests are instant. There don't appear to be any more
surprise latency spikes.
This _partially_ addresses #1650 in that it front-loads the latency of the
first goto-definition request, which in turn makes it more predictable and
less surprising. In particular, this addresses the use case where one opens
the text editor, starts reading code for a while, and only later issues the
first goto-definition request. Before this PR, that first goto-definition request
is guaranteed to have high latency in any reasonably sized project. But
after this PR, there's a good chance that it will now be instant.
What this _doesn't_ address is that initial loading time. In fact, it makes it
longer by adding a phantom goto-definition request to the initial startup
sequence. However, I observed that while this did make initial loading
slower, it was overall a somewhat small (but not insignificant) fraction
of initial loading time.
-----
At least, the above is what I _want_ to do. The actual change in this PR is just a proof-of-concept. I came up with after an evening of printf-debugging. Once I found the spot where this cache priming should go, I was unsure of how to generate a phantom input. So I just took an input I knew worked from my printf-debugging and hacked it in. Obviously, what I'd like to do is make this more general such that it will always work.
I don't know whether this is the "right" approach or not. My guess is that there is perhaps a cleaner solution that more directly primes whatever cache is being lazily populated rather than fudging the issue with a phantom goto-definition request.
I created this as a draft PR because I'd really like help making this general. I think whether y'all want to accept this patch is perhaps a separate question. IMO, it seems like a good idea, but to be honest, I'm happy to maintain this patch on my own since it's so trivial. But I would like to generalize it so that it will work in any project.
My thinking is that all I really need to do is find a file and a token somewhere in the loaded project, and then use that as input. But I don't quite know how to connect all the data structures to do that. Any help would be appreciated!

This commit makes RA more aggressive about eagerly priming the caches.
In particular, this fixes an issue where even after RA was done priming
its caches, an initial goto-definition request would have very high
latency. This fixes that issue by requesting syntax highlighting for
everything. It is presumed that this is a tad wasteful, but not overly
so.
This commit also tweaks the logic that determines when the cache is
primed. Namely, instead of just priming it when the state is loaded
initially, we attempt to prime it whenever some state changes. This
fixes an issue where if a modification notification is seen before cache
priming is done, it would stop the cache priming early.

3954: Improve autocompletion by looking on the type and name r=matklad a=bnjjj
This tweet (https://twitter.com/tjholowaychuk/status/1248918374731714560) gaves me the idea to implement that in rust-analyzer.
Basically for this first example I made some examples when we are in a function call definition. I look on the parameter list to prioritize autocompletions for the same types and if it's the same type + the same name then it's displayed first in the completion list.
So here is a draft, first step to open a discussion and know what you think about the implementation. It works (cf tests) but maybe I can make a better implementation at some places. Be careful the code needs some refactoring to be better and concise.
PS: It was lot of fun writing this haha

In general, there should be no reason to call `.to_string_lossy`.
If you want to display the path, use `.display()`.
If you want to pass the path to an OS API (like std::process::Command)
than use `PathBuf` or `OsString`.
4092: feat: run ignored tests r=matklad a=hdevalke
I started making some exercices on https://exercism.io/ and a lot of test have the `#[ignore]` attribute.
The `Run Test|Debug` code lens show up, but running the test results in:
```
running 1 test
test test_one_piece ... ignored
test result: ok. 0 passed; 0 failed; 1 ignored; 0 measured; 5 filtered out
```
This pull request adds the `--ignored` flag if needed.

This is a quick way to implement unresolved reference diagnostics.
For example, adding to VS Code config
"editor.tokenColorCustomizationsExperimental": {
"unresolvedReference": "#FF0000"
},
will highlight all unresolved refs in red.
3996: Fix path for proc-macro in nightly / stable release r=matklad a=edwin0cheng
I messed up that I forget we use different executable names for nightly / stable release, I changed to use the current executable name instead.
