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
