Support hovering limits for adts
Fix#17009
1. Currently, r-a supports limiting the number of struct fields displayed when hovering. This PR extends it to support enum variants and union fields. Since the display of these three (ADTs) is similar, this PR extends 'hover_show_structFields' to 'hover_show_adtFieldsOrVariants'.
2. This PR also resolved the problem that the layout of ADT was not restricted by display limitations when hovering on the Self type.
3. Additionally, this PR changes the default value of display limitations to `10` (instead of the original `null`), which helps users discover this feature.
* Added config `runnables.extraTestBinaryArgs` to control the args.
* The default is `--show-output` rather than `--nocapture` to prevent
unreadable output when 2 or more tests fail or print output at once.
* Renamed variables in `CargoTargetSpec::runnable_args()` for clarity.

feat: Add `rust-analyzer.cargo.allTargets` to configure passing `--all-targets` to cargo invocations
Closes#16859
## Unresolved question:
Should this be a setting for build scripts only ? All the other `--all-targets` I found where already covered by `checkOnSave.allTargets`
Refactor extension to support arbitrary shell command runnables
Currently, the extension assumes that all runnables invoke cargo. Arguments are sometimes full CLI arguments, and sometimes arguments passed to a cargo subcommand.
Refactor the extension so that tasks are just a `program` and a list of strings `args`, and rename `CargoTask` to `RustTask` to make it generic.
(This was factored out of #16135 and tidied.)
feat: Support multiple tab stops for completions in VSCode
Uses the native VSCode support for `SnippetTextEdit`s. Fixes#13229 and fixes#8531.
https://github.com/rust-lang/rust-analyzer/assets/13354275/a2d2c033-bb30-4f34-92ca-bf3f4f744cdc
This is done in a slightly hacky way, as `vscode-languageclient` can't convert RA's `SnippetTextEdit`s into vscode `SnippetTextEdit`s and will appear to use a [different format](295aaa393f/types/src/main.ts (L1501-L1516)) in the future.

~~Marked as draft since as-is, this will cause completions to double-indent any multi-line code generated.~~
**Update:** This also fixes up edits so that any multi-line code won't be double-indented.
We can't tell vscode to not add in the extra indentation, so we instead opt to remove it from the edits themselves, and then let vscode add it back in.
fix: Fix build scripts not being rebuilt in some occasions
Also makes proc-macro changed flag setting async, we don't wanna block `process_changes` on the database as that is on the main thread!
Substitute $saved_file in custom check commands
If the custom command has a $saved_file placeholder, and we know the file being saved, replace the placeholder and run a check command.
If there's a placeholder and we don't know the saved file, do nothing.
This is a simplified version of #15381, which I hope is easier to review.

file being saved, replace the placeholder and then run a check command.

feature: Create `UnindexedProject` notification to be sent to the client
(Note that this branch contains commits from https://github.com/rust-lang/rust-analyzer/pull/15830, which I'll rebase atop of as needed.)
Based on the discussion in https://github.com/rust-lang/rust-analyzer/issues/15837, I've added a notification and off-by-default toggle to send that notification from `handle_did_open_text_document`. I'm happy to rename/tweak this as needed.
I've been using this for a little bit, and it does seem to cause a little bit more indexing/work in rust-analyzer, but it's something that I'll profile as needed, I think.
With #15656 we started disallowing renaming of non-local items.
Although this makes sense there are some false positives that
impacted users' workflows. So this config aims to mitigate this
by giving users the liberty to disable this feature.
fix: Correct references from `rust-analyzer.cargo.check` to `rust-analyzer.check`
When reading the manual, I noticed that the documentation referenced configurations that have since been renamed. This PR updates those references to their new names.
fix: update VSCode rust-panic problem matcher
Corrected the `rust-panic` task problem matcher for the VSCode Extension to match the new panic message pattern.
From:
```
thread 'main' panicked at 'PANIC_MESSAGE', src/main.rs:L:C
```
To:
```
thread 'main' panicked at src/main.rs:L:C:
PANIC_MESSAGE
```
minor: Optimizing Performance with `Promise.all` 🏎
Hello,
This pull request introduces a modest performance improvement by executing asynchronous tasks using `Promise.all`, thereby enhancing the efficient utilization of hardware resources.
Thank you for considering this enhancement.

Show placeholder while run command gets runnables from server
This PR fixes a UI annoyance in the VS Code extension when working in large codebases where rust-analyzer can take a few moments to interact with the server. Scenario:
1. Invoke "rust-analyzer: Run" from the command palette or hotkey
2. Quickly start typing to filter the list (or press Enter to accept the last runnable)
We often do this quickly from muscle memory without waiting to see the picker. The picker often takes several seconds to come up, causing us to type garbage into the currently open editor.
Fix:
Show a placeholder item before we call out to the server.
Selecting this item does nothing so if the user accidentally hits Enter nothing happens.
The list is populated and the placeholder dismissed when the actual runnables are retrieved. From here the behavior is the same as before.
editor/code: add option to suppress error notifications
Fixes https://github.com/rust-lang/rust-analyzer/issues/14193
- Added the `rust-analyzer.showRequestFailedErrorNotification` configuration option, which defaults to `true`
- If `rust-analyzer.showRequestFailedErrorNotification` is set to `true`, the current behavior is preserved.
- If `rust-analyzer.showRequestFailedErrorNotification` is set to `false`, no error toasts will be displayed for any of the failed requests caused by panics in r-a. This _only_ applies to events that are triggered "implicitly", such as `textDocument/hover`.
To test this, you can manually introduce a panic in one of the language server LSP handlers for non-command events. I added an explicit `panic!()` in the `textDocument/hover` event handler:
#### `rust-analyzer.showRequestFailedErrorNotification` set to `true` (default)
[2023-11-07 17-17-48.webm](https://github.com/rust-lang/rust-analyzer/assets/1665677/d0408ab8-79d1-42cf-a4e7-94e99d9783ec)
#### `rust-analyzer.showRequestFailedErrorNotification` set to `false`
[2023-11-07 17-16-49.webm](https://github.com/rust-lang/rust-analyzer/assets/1665677/0496d8d0-fb53-4bc6-a279-1a47f412dbdb)
minor: Make "Expand macro" command title more explicit
Closes [#15856](https://github.com/rust-lang/rust-analyzer/issues/15856).
I opted for "caret", since it's the better term (cursor is the mouse), but I'm not sure how popular it is these days.
feat: vscode: Support opening local documentation if available
This PR implements the VS code support for opening local documentation (server side support was already implemented in #14662).
[local_docs.webm](https://github.com/rust-lang/rust-analyzer/assets/9659253/715b84dd-4f14-4ba0-a904-749b847eb3d5)
Displaying local instead of web docs can have many benefits:
- the web version may have different features enabled than locally selected
- the standard library may be a different version than is available online
- the user may not be online and therefore cannot access the web documentation
- the documentation may not be available online at all, for example because it is for a new feature in a library the user is currently developing
If the documentation is not available locally, the extension still falls back to the web version.
Closes#12867.

If my implementation isn't really idiomatic TypeScript: Sorry, I'm not much of a TypeScript developer. I am open to feedback, however.

Adds a Rust Analyzer configuration option to set a custom
target directory for builds. This is a workaround for Rust Analyzer
blocking debug builds while running `cargo check`. This change
should close#6007
According to the VS Code documentation, the vscode.open command opens the URL
_in the editor_ (https://code.visualstudio.com/api/references/commands).
However, in reality, it seems to do so only for file:// URLs, falling back to
other applications for other URL schemes (at least for HTTP/HTTPS).
Until now, the URL to the documentation was always HTTP based, so using the
vscode.open command was perfectly fine. However, displaying local documentation
will be supported from now on (see next commit). Local documentation is not
HTTP-based, but instead addressed via a file:// URL. The file URL would
therefore be opened in VS Code instead of in the browser — this is definitely
not what the user wants.
Therefore, the vscode.env.openExternal function is used instead, this function
never opens the URL in VS Code.
feat: add backtick to surrounding and auto-closing pairs
Makes backticks always complete as a pair and also surround the current selection, similar to double quotes. This is useful primarily in the context of markdown doc comments, but is applied globally for simplicity.
Closes https://github.com/rust-lang/rust-analyzer/issues/11381
When building the Rust compiler with `./x check` from within VS Code,
the current `rustc` problem matcher thinks that the output from that
command that looks like this:
Build completed successfully in 0:00:26
is about a problem in a file named `0` on line 00, col 26. This wouldn't
be so bad if it wasn't for that VS Code tends to get stuck on this
problem because of problems with opening the file '0'.
The rust compiler will never output problems with a line or a column
that starts with 0, so change the regexp to require lines and cols to
begin with [1-9] to fix this problem.
extend check.overrideCommand and buildScripts.overrideCommand docs
Extend check.overrideCommand and buildScripts.overrideCommand docs regarding invocation strategy and location.
However something still seems a bit odd -- the docs for `invocationStrategy`/`invocationLocation` talk about "workspaces", but the setting that controls which workspaces are considered is called `linkedProjects`. Is a project the same as a workspace here or is there some subtle difference?
