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.
Only run tests on linux in pull requests
There is little gain from running them on all platforms, they should almost never fail if the linux one pass and if they do, bors will catch it still.
fix: make bool_to_enum assist create enum at top-level
This pr makes the `bool_to_enum` assist create the `enum` at the next closest module block or at top-level, which fixes a few tricky cases such as with an associated `const` in a trait or module:
```rust
trait Foo {
const $0BOOL: bool;
}
impl Foo for usize {
const BOOL: bool = true;
}
fn main() {
if <usize as Foo>::BOOL {
println!("foo");
}
}
```
Which now properly produces:
```rust
#[derive(PartialEq, Eq)]
enum Bool { True, False }
trait Foo {
const BOOL: Bool;
}
impl Foo for usize {
const BOOL: Bool = Bool::True;
}
fn main() {
if <usize as Foo>::BOOL == Bool::True {
println!("foo");
}
}
```
I also think it's a bit nicer, especially for local variables, but didn't really know to do it in the first PR :)
Allocate ast ids for parameters
Since these can have attributes attached to them, we'll need this sooner or later (sooner being me tinkering with the token map right now)
fix: panic with wrapping/unwrapping result return type assists
With the `wrap_return_type_in_result` assist, the following code results in a panic (note the lack of a semicolon):
```rust
fn foo(num: i32) -> $0i32 {
return num
}
=>
thread 'handlers::wrap_return_type_in_result::tests::wrap_return_in_tail_position' panicked at crates/syntax/src/ted.rs:137:41:
called `Option::unwrap()` on a `None` value
```
I think this is because it first walks the body expression to change any `return` expressions and then walks all tail expressions, resulting in the `return num` being changed twice since it is both a `return` and in tail position. This can also happen when a `match` is in tail position and `return` is used in a branch for example. Not really sure how big of an issue this is in practice though since this seems to be the only case that is impacted and can be reduced to just `num` instead of `return num`.
This also occurs with the `unwrap_result_return_type` assist but panics with the following instead:
```
thread 'handlers::unwrap_result_return_type::tests::wrap_return_in_tail_position' panicked at /rustc/3223b0b5e8dadda3f76c3fd1a8d6c5addc09599e/library/alloc/src/string.rs:1766:29:
assertion failed: self.is_char_boundary(n)
```
minor: hover_simple refactor
A minor refactor of `hover_simple` opportunity I noticed while skimming through the code.
- `if let`s -> `match`
- `iter::once(x).cycle` -> `iter::repeat`
- `classify_token` -> `classify_node`
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?
minor : Deunwrap convert_comment_block and desugar_doc_comment
Closes subtask 13 of #15398 . I still don't know a more idiomatic way for the for loops I added, any suggestion would make me happy.
Although it doesn't panic now, further changes to how we recover from incomplete syntax
may cause this assist to panic. To mitigate this a test case has been added.
