Instead of using `core::fmt::format` to format panic messages, which may in turn
panic too and cause recursive panics and other messy things, redirect
`panic_fmt` to `const_panic_fmt` like CTFE, which in turn goes to
`panic_display` and does the things normally. See the tests for the full
call stack.
internal: Enforce utf8 paths
Cargo already requires this, and I highly doubt r-a works with non-utf8 paths generally either. This just makes dealing with paths a lot easier.
feat: Syntax highlighting improvements
Specifically
- Adds a new `constant` modifier, attached to keyword `const` (except for `*const ()` and `&raw const ()`), `const` items and `const` functions
- Adds (or rather reveals) `associated` modifier for associated items
- Fixes usage of the standard `static` modifier, now it acts like `associated` except being omitted for methods.
- Splits `SymbolKind::Function` into `Function` and `Method`. We already split other things like that (notable self param from params), so the split makes sense in general as a lot special cases around it anyways.
fix: Fix wrong where clause rendering on hover
We were not accounting for proper newline indentation in some places making the hover look weird (or just straight up wrong for type aliases)
internal: Compress file text using LZ4
I haven't tested properly, but this roughly looks like:
```
1246 MB
59mb 4899 FileTextQuery
1008 MB
20mb 4899 CompressedFileTextQuery
555kb 1790 FileTextQuery
```
We might want to test on something more interesting, like `bevy`.
Add more methods for resolving definitions from AST to their corresponding HIR types
In order to be able to add these methods with consistent naming I had to also rename two existing methods that would otherwise be conflicting/confusing:
`Semantics::to_module_def(&self, file: FileId) -> Option<Module>` (before)
`Semantics::file_to_module_def(&self, file: FileId) -> Option<Module>` (after)
`Semantics::to_module_defs(&self, file: FileId) -> impl Iterator<Item = Module>` (before)
`Semantics::file_to_module_defs(&self, file: FileId) -> impl Iterator<Item = Module>` (after)
(the PR is motivated by an outside use of the `ra_ap_hir` crate that would benefit from being able to walk a `hir::Function`'s AST, resolving its exprs/stmts/items to their HIR equivalents)
fix: use 4 spaces for indentation in macro expansion
Partial fix for #16471.
In the previous code, the indentation produced by macro expansion was set to 2 spaces. This PR modifies it to 4 spaces for the sake of consistency.
test: include `rename_path_inside_use_tree`.
Keeps tracks the progress of the changes. 3 other tests broke with the changes
of this.
feat: rename all other usages within the current file.
feat: fix most of the implementation problems.
test: `rename_path_inside_use_tree` tests a more complicated scenario.
Previously, the documentation field was the same as the text shown to
users when they hover over that symbol. The documentation should
really just be the doc comment, and as of #16179 the signature is
already stored in the signatureDocumentation field.
Abstract more over ItemTreeLoc-like structs
Allows reducing some code duplication by using functions generic over said structs. The diff isn't negative due to me adding some additional impls for completeness.
This commit also adds `tracing` to NotificationDispatcher/RequestDispatcher,
bumps `rust-analyzer-salsa` to 0.17.0-pre.6, `always-assert` to 0.2, and
removes the homegrown `hprof` implementation in favor of a vendored
tracing-span-tree.
feat: Support for GOTO def from *inside* files included with include! macro
close#14937
Try to implement goto def from *inside* files included with include! macro.
This implementation has two limitations:
1. Only **one** file which calls include! will be tracked. (I think multiple file be included is a rare case and we may let it go for now)
2. Mapping token from included file to macro call file (semantics.rs:646~658) works fine but I am not sure is this the correct way to implement.
Expand lint tables && make clippy happy 🎉
This PR expands the lint tables on `./Cargo.toml` and thereby makes `cargo clippy` exit successfully! 🎉Fixes#15918
## How?
In the beginning there are some warnings for rustc.
Next, and most importantly, there is the clippy lint table. There are a few sections in there.
First there are the lint groups.
Second there are all lints which are permanently allowed with the reasoning why they are allowed.
Third there is a huge list of temporarily allowed lints. They should be removed in the mid-term, but incur a substantial amount of work, therefore they are allowed for now and can be worked on bit by bit.
Fourth there are all lints which should warn.
Additionally there are a few allow statements in the code for lints which should be permanently allowed in this specific place, but not in the whole code base.
## Follow up work
- [ ] Run clippy in CI
- [ ] Remove tidy test (at least `@Veykril` wrote this in #15017)
- [ ] Work on temporarily allowed lints
`cargo clippy --fix`
This PR is the result of running `cargo clippy --fix && cargo fmt` in the root of the repository. I did not manually review all the changes, but just skimmed through a few of them. The tests still pass, so it seems fine.
Add a new config to allow renaming of non-local defs
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.
The reason why this is a draft is that I saw one of the tests fail and I am not sure if the "got" result even syntactically makes sense
Test case is :
```rust
check(
"Baz",
r#"
//- /lib.rs crate:lib new_source_root:library
pub struct S;
//- /main.rs crate:main deps:lib new_source_root:local
use lib::S$0;
"#,
"use lib::Baz;"
);
```
```
Left:
use lib::Baz;
Right:
use lib::Baz;Baz
Diff:
use lib::Baz;Baz
```
The first one succeeds because the functionality is already implemented.
The second one fails and represents the functionality to be implemented
in this PR.
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.
internal: Only compare relevant parts in `ide::{runnables,inlay_hints}` tests
This PR limits the data being compared. Therefore the tests should be more readable, as well as being more robust to changes to the data structure.
Part of https://github.com/rust-lang/rust-analyzer/issues/14268.
internal: Move query limits to the caller
Prior we calculated up to `limit` entries from a query, then filtered from that leaving us with less entries than the limit in some cases (which might give odd completion behavior due to items disappearing). This changes it so we filter before checking the limit.
feat: resolve inherent and implemented associated items in docs
This partially fixes#9694.
Supported:
- Trait methods and constants.
* Due to resolution differences pointed out during the review of the PR, trait associated types are _not_ supported.
- Inherent methods, constants and associated types.
* Inherent associated types are a [nightly feature](https://github.com/rust-lang/rust/issues/8995), and are supported with no additional work in this PR.
Screenshot of VS Code running with the change:
<img width="513" alt="image" src="https://github.com/rust-lang/rust-analyzer/assets/7189784/c37ed8b7-b572-4684-8e81-2a817b0027c4">
You can see that the items are resolved (excl. trait associated types) since they are semantically highlighted in the doc comment.
SymbolInformation::kind is finer-grained than the SCIP symbol suffix.
This also fixes a bug where all type aliases where treated like type
parameters.
```
trait SomeTrait {
type AssociatedType; // ← this is SomeTrait#[AssociatedType]
}
type MyTypeAlias = u8; // ← this used to be [MyTypeAlias]
// and now is MyTypeAlias#
```
To build the SymbolInformation::signature_documentation we need access
to the “label” when building the TokenStaticData, preferably without
any markdown markup.
Therefore this refactors ide::hover::render::definition and its helper
functions to give easier access to the label alone.
For local variables, this gets the moniker from the enclosing
definition and stores it into the TokenStaticData.
Then it builds the scip symbol for that moniker when building the
SymbolInformation.
Complete exported macros in `#[macro_use($0)]`
Closes https://github.com/rust-lang/rust-analyzer/issues/15657.
Originally added a test case for incomplete input:
```rust
#[test]
fn completes_incomplete_syntax() {
check(
r#"
//- /dep.rs crate:dep
#[macro_export]
macro_rules! foo {
() => {};
}
//- /main.rs crate:main deps:dep
#[macro_use($0
extern crate dep;
"#,
expect![[r#"
ma foo
"#]],
)
}
```
but couldn't make it pass and removed it 😅 Our current recovering logic doesn't work for token trees and for this code:
```rust
#[macro_use(
extern crate lazy_static;
fn main() {}
```
we ended up with this syntax tree:
```
SOURCE_FILE@0..53
ATTR@0..52
POUND@0..1 "#"
L_BRACK@1..2 "["
META@2..52
PATH@2..11
PATH_SEGMENT@2..11
NAME_REF@2..11
IDENT@2..11 "macro_use"
TOKEN_TREE@11..52
L_PAREN@11..12 "("
WHITESPACE@12..13 "\n"
EXTERN_KW@13..19 "extern"
WHITESPACE@19..20 " "
CRATE_KW@20..25 "crate"
WHITESPACE@25..26 " "
IDENT@26..37 "lazy_static"
SEMICOLON@37..38 ";"
WHITESPACE@38..40 "\n\n"
FN_KW@40..42 "fn"
WHITESPACE@42..43 " "
IDENT@43..47 "main"
TOKEN_TREE@47..49
L_PAREN@47..48 "("
R_PAREN@48..49 ")"
WHITESPACE@49..50 " "
TOKEN_TREE@50..52
L_CURLY@50..51 "{"
R_CURLY@51..52 "}"
WHITESPACE@52..53 "\n"
```
Maybe we can try to parse the token tree in `crates/ide-completion/src/context/analysis.rs` but I'm not sure what's the best way forward.
fix: Update metavariable expression implementation
Fixes https://github.com/rust-lang/rust-analyzer/issues/16154
This duplicates behavior of that before and after PR https://github.com/rust-lang/rust/pull/117050 based on the toolchain version. There are some 1.76 nightlies that are still broken (any before that PR basically) but fetching and storing the commit makes little sense to me (opposed to the toolchain version).
