## Description
Fixes trailing ':' even when there is no explanation. e.g.
``` sh
code is inactive due to #[cfg] directives:

feat: implement destructuring assignment
This is an attempt to implement destructuring assignments, or more specifically, type inference for [assignee expressions](https://doc.rust-lang.org/reference/expressions.html#place-expressions-and-value-expressions).
I'm not sure if this is the right approach, so I don't even expect this to be merged (hence the branch name 😉) but rather want to propose one direction we could choose. I don't mind getting merged if this is good enough though!
Some notes on the implementation choices:
- Assignee expressions are **not** desugared on HIR level unlike rustc, but are inferred directly along with other expressions. This matches the processing of other syntaxes that are desugared in rustc but not in r-a. I find this reasonable because r-a only needs to infer types and it's easier to relate AST nodes and HIR nodes, so I followed it.
- Assignee expressions obviously resemble patterns, so type inference for each kind of pattern and its corresponding assignee expressions share a significant amount of logic. I tried to reuse the type inference functions for patterns by introducing `PatLike` trait which generalizes assignee expressions and patterns.
- This is not the most elegant solution I suspect (and I really don't like the name of the trait!), but it's cleaner and the change is smaller than other ways I experimented, like making the functions generic without such trait, or making them take `Either<ExprId, PatId>` in place of `PatId`.
in case this is merged:

fix: Improve proc macro errors a bit
Distinguish between
- there is no build data (for some reason?)
- there is build data, but the cargo package didn't build a proc macro dylib
- there is a proc macro dylib, but it didn't contain the proc macro we expected
- the name did not resolve to any macro (this is now an
unresolved_macro_call even for attributes)
I changed the handling of disabled attribute macro expansion to
immediately ignore the macro and report an unresolved_proc_macro,
because otherwise they would now result in loud unresolved_macro_call
errors. I hope this doesn't break anything.
Also try to improve error ranges for unresolved_macro_call / macro_error
by reusing the code for unresolved_proc_macro. It's not perfect but
probably better than before.

fix: doc_links link type - Determine link type at start (fixes#12601)
fixes#12601
Looked like autolink/inline mismatch happened because end_link_type was parsed from the Text/Code events.
I changed it to be determined from the Start event, which should hopefully remain accurate while staying true to the cases where link type may need to be changed, according to the comment
```
// normally link's type is determined by the type of link tag in the end event,
// however in some cases we want to change the link type, for example,
// `Shortcut` type doesn't make sense for url links
```
Hopefully this is the desired behavior?
- remove Valid, it serves no purpose and just obscures the diff
- rename some things
- don't use is_valid_candidate when searching for impl, it's not necessary
fix: Only apply `cfg(test)` for local crates
Don't analyze dependencies with `test`; this should fix various cases where crates use `cfg(not(test))` and so we didn't find things.
"Local" here currently means anything that's not from the registry, so anything inside the workspace, but also path dependencies. So this isn't perfect, and users might still need to use `rust-analyzer.cargo.unsetTest` for these in some cases.

fix: local items should not be completed in parent signature
fixes#11959
> We get a Bar completion for the following snippet which is wrong as the item is not visible in that position.
> ``` rust
> fn foo() -> $0 {
> struct Bar;
> }
> ```
I investigated the problem and found that the scope of the cursor offset, also `CompletionContext.scope` is the body of the function
fix methods in pub trait generated by macro cannot be completed
Fix#12483
Check if the container is trait and inherit the visibility to associate items during collection.
fix: Pass the build data to rustc_private crates
With this all proc-macros should resolve in rustc now when setting up the build script running command properly.
fix: #12441 False-positive type-mismatch error with generic future
I think the reason is same with #11815.
add ```Sized``` bound for ```AsyncBlockTypeImplTrait```.
Order auto-imports by relevance
Fixes#10337.
Basically we sort the imports according to how "far away" the imported item is from where we want to import it to. This change makes it so that imports from the current crate are sorted before any third-party crates. Additionally, we make an exception for builtin crates (`std`, `core`, etc.) so that they are sorted before any third-party crates.
There are probably other heuristics that should be added to improve the experience (such as preferring imports that are common elsewhere in the same crate, and ranking crates depending on the dependency graph). However, I think this is a first good step.
PS. This is my first time contributing here, so please be gentle if I have missed something obvious :-)
feature: `Merge imports` assist can merge multiple selected imports.
The selected imports have to have a common prefix in paths.
Select imports or use trees to merge:
```rust
$0use std::fmt::Display;
use std::fmt::Debug;
use std::fmt::Write;$0
```
Apply `Merge imports`:
```rust
use std::fmt::{Display, Debug, Write};
```
Closes#12426

Before
```rust

After
```rust
use std::fmt::{Display, Debug};

fix(extract_module) resolving import panics and improve import resolution
- Should solve #11766
- While adding a test case for this issue, I observed another issue:
For this test case:
```rust
mod x {
pub struct Foo;
pub struct Bar;
}
use x::{Bar, Foo};
$0type A = (Foo, Bar);$0
```
extract module should yield this:
```rust
mod x {
pub struct Foo;
pub struct Bar;
}
use x::{};
mod modname {
use super:❌:Bar;
use super:❌:Foo;
pub(crate) type A = (Foo, Bar);
}
```
instead it gave:
```rust
mod x {
pub struct Foo;
pub struct Bar;
}
use x::{};
mod modname {
use x::Bar;
use x::Foo;
pub(crate) type A = (Foo, Bar);
}
```
So fixed this problem with second commit
fix(ide-db): correct single-file module rename
Fixes a bug where rust-analyzer would emit `WorkspaceEdit`s with paths to dirs instead of files for the following project layout.
lib.rs
```rust
mod foo;
```
foo.rs
```rust
mod bar {
struct Bar;
}
```
Also fixes emitted paths for modules with mod.rs.
The bug resulted in panic in helix editor when attempting to rename a module.
fix: Retrigger visibility completion after parentheses
close#12390
This PR add `(` to trigger_characters as discussed in original issue.
Some questions:
1. Is lsp's `ctx.trigger_character` from `params.context` is the same as `ctx.original_token` inside actually completions?
1. If not what's the difference?
2. if they are the same, it's unnecessary to pass it down from handler at all.
3. if they are the same, maybe we could parse it from fixture directly instead of using the `check_with_trigger_character` I added.
2. Some completion fixtures written as `($0)` ( https://github.com/rust-lang/rust-analyzer/blob/master/crates/ide-completion/src/tests/fn_param.rs#L105 as an example), If I understand correctly they are not invoked outside tests at all?
1. using `ctx.original_token` directly would break these tests as well as parsing trigger_character from fixture for now.
2. I think it make sense to allow `(` triggering these cases?
3. I hope this line up with #12144
make `files.excludeDirs` work
There's a small issue because if all projects are excluded, this: 01d412f4d7/crates/rust-analyzer/src/main_loop.rs (L114) will be shown.
I thought about not showing it if `files.excludeDirs` is set, but that is not necessarily correct.
Fixes#7755
Fix inference when pattern matching a tuple field with a wildcard
This should fix the following issue: https://github.com/rust-lang/rust-analyzer/issues/12331
* Replaced the `err_ty` in `infer_pat()` with a new type variable.
* Had to change the iterator code a bit, to get around multiple mutable borrows of `self` in `infer_pat()`.
Also added a test
* Also added a test
Generate enum variant assist
So, this is kind of a weird PR!
I'm a complete newcomer to the `rust-analyzer` codebase, and so I browsed the "good first issue" tag, and found #11635. Then I found two separate folks had taken stabs at it, most recently `@maartenflippo` — and there had been a review 3 days ago, but no activity in a little while, and the PR needed to be rebased since the crates were renamed from `snake_case` to `kebab-case`.
So to get acquainted with the codebase I typed this PR by hand, looking at the diff in #11995, and I also added a doc-test (that passes).
I haven't taken into account the comments `@Veykril` left in #11995, but I don't want to steal any of `@maartenflippo's` thunder! Closing this PR is perfectly fine. Or Maarten could use it as a "restart point"? Or I could finish it up, whichever feels best to everyone.
I think what remains to be done in this PR, at least, is:
* [x] Only disable the "generate function" assist if the name is `PascalCase`
* [x] Only enable the "generate variant" assistant if the name is `PascalCase`
* [x] Simplify with `adt.source()` as mentioned here: https://github.com/rust-lang/rust-analyzer/pull/11995#discussion_r875134175
* [ ] Add more tests for edge cases? Are there cases where simply adding one more indent level than the enum's indent level is not good enough? Some nested trickery I'm not thinking of right now?
Anyway. This PR can go in any direction. You can tell me "no, tackle your own issue!" And I'll go do that and still be happy I got to take a look at rust-analyzer some by doing this. Or you can tell me "okay, now _you_ finish it", and I guess I'll try and finish it :)
