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.
Fix autoimport does nothing when importing trait that is as _ imports
Potentially fixes#15128
There are two cases of imports:
1. With simple path
2. With use tree list (or say complex path).
On deeper inspection, the [`recursive_merge`](994df3d6a3/crates/ide-db/src/imports/merge_imports.rs (L87)) function (called by [`try_merge_trees_mut`)](994df3d6a3/crates/ide-db/src/imports/merge_imports.rs (L69)) is meaningful only in the case of complex path (i.e when the UseTree contains a UseTreeList).
The [`recursive_merge`](994df3d6a3/crates/ide-db/src/imports/merge_imports.rs (L87)) function has [match with `Ok` arm](994df3d6a3/crates/ide-db/src/imports/merge_imports.rs (L106)), that is only executed when both LHS and RHS has `PathSegment` with same `NameRef`. The removal of underscore is implemented in this arm in the case of complex path.
For simple paths, the underscore is removed by checking if both LHS and RHS are simple paths and if their `Path` is same (the check is done [here](994df3d6a3/crates/ide-db/src/imports/merge_imports.rs (L74))) and remove the underscore if one is found (I made an assumption here that RHS will always be what rust-analyzer suggests to import, because at this point I'm not sure how to remove underscore with help of `ted::replace`).
feat: Bool to enum assist
This adds the `bool_to_enum` assist, which converts the type of boolean local variables, fields, constants and statics to a new `enum` type, making it easier to distinguish the meaning of `true` and `false` by renaming the variants.
Closes#14779
Give `unmerge_use` a label explaining what it will affect.
When I'm trying to clean up `use`s, I often feel uncertain about what exactly the effects of choosing an assist will be. This PR makes a small improvement to that by giving “Unmerge use” a label which names the root of the tree that it's going to move, when one exists.
There is no test because I didn't see, among the test helpers, a way to assert on the assist label (as opposed to filtering on it). However, I did test the change manually.
I looked into making a similar change to “Merge imports”, but that is considerably trickier.
VSCode behaves strangely, allowing to navigate into label location, but
not allowing to apply hint's text edit, after hint is resolved.
See https://github.com/microsoft/vscode/issues/193124 for details.
For now, stub hint resolution for VSCode specifically.
Switch to in-tree rustc dependencies with a cfg flag
We can use this flag to detect and prevent breakages in rustc CI. (see #14846 and #15569)
~The `IN_RUSTC_REPOSITORY` is just a placeholder. Is there any existing cfg flag that rustc CI sets?~
Field shorthand overwritten in promote local to const assist
Currently, running `promote_local_to_const` on the following:
```rust
struct Foo {
bar: usize,
}
fn main() {
let $0bar = 0;
let foo = Foo { bar };
}
```
Results in:
```rust
struct Foo {
bar: usize,
}
fn main() {
const BAR: usize = 0;
let foo = Foo { BAR };
}
```
But instead should be something like:
```rust
struct Foo {
bar: usize,
}
fn main() {
const BAR: usize = 0;
let foo = Foo { bar: BAR };
}
```
project-model: when using `rust-project.json`, prefer the sysroot-defined rustc over discovery in `$PATH`
At the moment, rust-analyzer discovers `rustc` via the `$PATH` even if the `sysroot` field is defined in a `rust-project.json`. However, this does not work for users who do not have rustup installed, resulting in any `cfg`-based inference in rust-analzyer not working correctly. In my (decently naive!) opinion, it makes more sense to rely on the `sysroot` field in the `rust-project.json`.
One might ask "why not add `rustc` to the `$PATH`?" That is a reasonable question, but that doesn't work for my use case:
- The path to the sysroot in my employer's monorepo changes depending on which platform a user is on. For example, if they're on Linux, they'd want to use the sysroot defined at path `a`, whereas if they're on macOS, they'd want to use the sysroot at path `b` (I wrote the sysroot resolution functionality [here](765da4ca1e/integrations/rust-project/src/sysroot.rs (L39)), if you're curious).
- The location of the sysroot can (and does!) change, especially as people figure out how to make Rust run successfully on non-Linux platforms (e.g., iOS, Android, etc.) in a monorepo. Updating people's `$PATH` company-wide is hard while updating a config inside a CLI is pretty easy.
## Testing
I've created a `rust-project.json` using [rust-project](https://github.com/facebook/buck2/tree/main/integrations/rust-project) and was able to successfully load a project with and without the `sysroot`/`sysroot_src` fields—without those fields, rust-analyzer fell back to the `$PATH` based approach, as evidenced by `[DEBUG project_model::rustc_cfg] using rustc from env rustc="rustc"` showing up in the logs.
Resolve inlay hint data
Part of https://github.com/rust-lang/rust-analyzer/issues/13962
Support https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#inlayHint_resolve better, by omitting all inlay hint fields specified in the client hint resolve capabilities.
Current list of all capabilities possible to resolve later:
```
"textEdits"
"tooltip"
"label.tooltip"
"label.location"
"label.command"
```
and every one specified in the client capabilities is now resolved by r-a, being omitted in the initial response.

When editing `inlay_hints.rs` file around line `457` with no resolve capabilities, I get

Enable `rust_analyzer` for cfgs when code is being analyzed by rust-analyzer
This allows one to have r-a skip analysis/replace macros that work not well with r-a at all by gating them behind this cfg (an example being the `quote` macro which r-a struggles with in terms of performance).
Do not send inlay hint refresh requests on file edits
See https://github.com/rust-lang/rust-analyzer/issues/13369#issuecomment-1695306870
Editor itself is able to invalidate hints after edits, and /refresh was sent after editor reports changes to the language server. This forces the editor to either query & invalidate the hints twice after every edit, or wait for /refresh to come before querying the hints.
Both options are rather useless, so instead, send a request on server startup only: client editors do not know when the server actually starts up, this will help to query the initial hints after editor was open and the server was still starting up.
Bind unused parameter assistant
This PR introduces a new **Bind unused parameter assistant**.
While we do have a QuickFix from `rustc` (prefixing the parameter with an underscore), it's sometimes more convenient to suppress the warning using the following approach:
```rust
fn some_function(unused: i32) {}
```
->
```rust
fn some_function(unused: i32) {
let _ = unused;
}
```
minor : use crate name for `CARGO_CRATE_NAME`
fixes#15572 . Until now we used the package name as a replacement of crate name. With this PR r-a first sets all the env variables it set before and on top of those it tries to set `CARGO_CRATE_NAME` to crates name, following envvar's naming convention.
Replace format-args parser with upstream fork
Turns out we can't bump rustc_abi right now because it got its generics removed accidentally https://github.com/rust-lang/rust/pull/107163
On type format '(', by adding closing ')' automatically
If I understand right, `()` can surround pretty much the same `{}` can, so add another on type formatting pair for convenience: sometimes it's not that pleasant to write parenthesis in `Some(2).map(|i| (i, i+1))` cases and I would prefer r-a to do that for me.
One note: currently, b06503b6ec/crates/rust-analyzer/src/handlers/request.rs (L357) fires always.
Should we remove the assertion entirely now, since apparently things work in release despite that check?
Implement `write_via_move` intrinsic for mir-eval
Required for getting `write!`ing to work again. we fail with an odd type mimsatch eval error after this change though
Implement builtin#format_args, using rustc's format_args parser
`format_args!` now expands to `builtin#format_args(template, args...)`, the actual expansion now instead happens in lowering where we desugar this expression by using lang paths.
As a bonus, we no longer need to evaluate `format_args` as an eager macro which means less macro expansions overall -> less cache thrashing!

Add a few more `db.unwind_if_cancelled()` calls
Judging from a profile sent by a friend, the borrowck query took up a significant amount of time in their project which might be the cause for some unresponsiveness as nothing in the mir stack currently unwinds on cancellation
Shuffle some locking around
The main thread is still occasionally blocking on something and I am unsure what the cause might be. This will hopefully help somewhat
Editor itself is able to invalidate hints after edits, and /refresh was
sent after editor reports changes to the language server.
This forces the editor to either query & invalidate the hints twice
after every edit, or wait for /refresh to come before querying the
hints.
Both options are rather useless, so instead, send a request on server
startup only: client editors do not know when the server actually starts
up, this will help to query the initial hints after editor was open and
the server was still starting up.
Fix cargo handle logging in flycheck
This PR has two commits, so it's probably easier to review them separately:
(1) Rename `CargoHandle` to `CommandHandle`, as the command may not be a cargo command.
(2) Logging should format the current command, rather than calling `check_command()` again. This ensures that any later configuration changes don't cause us to log incorrect information.
proc-macro-test: Pass target to cargo invocation
When cross compiling macos → dragonfly the dist build fails in the proc-maro-test-impl crate with the following error:
`ld: unknown option: -z\nclang: error: linker command failed with exit code 1 (use -v to see invocation)`
This appears to be a wart stemming from using an Apple host for cross compiling. Passing the target along to cargo allows it to pick up a linker that it understands and DTRT.
Previously this was hard coded to "0.1". The SCIP protocol allows this
to be an arbitrary string:
```
message ToolInfo {
// Name of the indexer that produced this index.
string name = 1;
// Version of the indexer that produced this index.
string version = 2;
// Command-line arguments that were used to invoke this indexer.
repeated string arguments = 3;
}
```
so use the same string reported by `rust-analyzer --version`.
Warn on elided lifetimes in associated constants (`ELIDED_LIFETIMES_IN_ASSOCIATED_CONSTANT`)
Elided lifetimes in associated constants (in impls) erroneously resolve to fresh lifetime parameters on the impl since #97313. This is not correct behavior (see #38831).
I originally opened #114716 to fix this, but given the time that has passed, the crater results seem pretty bad: https://github.com/rust-lang/rust/pull/114716#issuecomment-1682091952
This PR alternatively implements a lint against this behavior, and I'm hoping to bump this to deny in a few versions.
fix help text for rust-analyzer.check.invocation{Strategy,Location}
I highly doubt that `check.invocationLocation` only has an effect if `cargo.buildScripts.overrideCommand` is set -- looks like a copy-paste mistake from `buildScripts.invocationLocation` to me.
minor : Deunwrap generate_derive
#15398 subtask 1. Since the editing closure has arms, I did something *experimental* ( in this case just a clever term for bad code ) to bypass creating an `Option` but I am ready to change this.
internal: Record import origins in ItemScope and PerNS
This records the import items definitions come from in the module scope (as well as what an import resolves to in an ItemScope). It does ignore glob imports as thats a lot more work for little to no gain, glob imports act as if the importing items are "inlined" into the scope which suffices for almost all use cases I believe (to my knowledge, attributes on them have little effect).
There is still a lot of work needed to make this available to the IDE layer, but this lays out the ground work for havin IDE layer support.

fix: start hovering default values of generic constants
It's just a kind of a postscriptum for [my last PR](https://github.com/rust-lang/rust-analyzer/pull/15179) adding default values of const generics to `hir::ConstParamData`. Here I patch other pieces of code which used to ignore const default values and which I managed to find (you're welcome to show me more)
the "add missing members" assists: implemented substitution of default values of const params
To achieve this, I've made `hir::ConstParamData` store the default values
internal : rewrite DeMorgan assist
fixes#15239 , #15240 . This PR is a rewrite of the DeMorgan assist that essentially rids of all the string manipulation and modifies syntax trees to apply demorgan on a binary expr. The main reason for the rewrite is that I wanted to use `Expr::needs_parens_in` method to see if the expr on which the assist is applied would still need the parens it had once the parent expression's operator had equal precedence with that of the expression. I used `.clone_(subtree|for_update)` left and right and probably more than I should have, so I would also be happy to hear how I could have prevented redundant cloning.
Suggest type completions for type arguments and constant completions for constant arguments
When determining completions for generic arguments, suggest only types or only constants if the corresponding generic parameter is a type parameter or constant parameter.
Closes#12568
Fix signature help of methods from macros
Currently the receiver type is copied from AST instead re-formatting through `HirDisplay`. Macro generated functions seem to have no spaces and their signature help are rendered like `fn foo(&'amutself)` instead of `fn foo(&'a mut self)`.
Fix pinned version of lsp-types
lsp-types published a new patch version that breaks semver with the proposed feature set (this is intended and documented), we unfortunately forgot to specify the patch version for the pinned version so this breaks us.
Similar to prior support added for the mips430, avr, and x86 targets
this change implements the rough equivalent of clang's
[`__attribute__((interrupt))`][clang-attr] for riscv targets, enabling
e.g.
```rust
static mut CNT: usize = 0;
pub extern "riscv-interrupt-m" fn isr_m() {
unsafe {
CNT += 1;
}
}
```
to produce highly effective assembly like:
```asm
pub extern "riscv-interrupt-m" fn isr_m() {
420003a0: 1141 addi sp,sp,-16
unsafe {
CNT += 1;
420003a2: c62a sw a0,12(sp)
420003a4: c42e sw a1,8(sp)
420003a6: 3fc80537 lui a0,0x3fc80
420003aa: 63c52583 lw a1,1596(a0) # 3fc8063c <_ZN12esp_riscv_rt3CNT17hcec3e3a214887d53E.0>
420003ae: 0585 addi a1,a1,1
420003b0: 62b52e23 sw a1,1596(a0)
}
}
420003b4: 4532 lw a0,12(sp)
420003b6: 45a2 lw a1,8(sp)
420003b8: 0141 addi sp,sp,16
420003ba: 30200073 mret
```
(disassembly via `riscv64-unknown-elf-objdump -C -S --disassemble ./esp32c3-hal/target/riscv32imc-unknown-none-elf/release/examples/gpio_interrupt`)
This outcome is superior to hand-coded interrupt routines which, lacking
visibility into any non-assembly body of the interrupt handler, have to
be very conservative and save the [entire CPU state to the stack
frame][full-frame-save]. By instead asking LLVM to only save the
registers that it uses, we defer the decision to the tool with the best
context: it can more accurately account for the cost of spills if it
knows that every additional register used is already at the cost of an
implicit spill.
At the LLVM level, this is apparently [implemented by] marking every
register as "[callee-save]," matching the semantics of an interrupt
handler nicely (it has to leave the CPU state just as it found it after
its `{m|s}ret`).
This approach is not suitable for every interrupt handler, as it makes
no attempt to e.g. save the state in a user-accessible stack frame. For
a full discussion of those challenges and tradeoffs, please refer to
[the interrupt calling conventions RFC][rfc].
Inside rustc, this implementation differs from prior art because LLVM
does not expose the "all-saved" function flavor as a calling convention
directly, instead preferring to use an attribute that allows for
differentiating between "machine-mode" and "superivsor-mode" interrupts.
Finally, some effort has been made to guide those who may not yet be
aware of the differences between machine-mode and supervisor-mode
interrupts as to why no `riscv-interrupt` calling convention is exposed
through rustc, and similarly for why `riscv-interrupt-u` makes no
appearance (as it would complicate future LLVM upgrades).

internal: use `Cast::cast()` instead of explicit interning
I firmly believe that we should generally use `cast()` instead of interning `GenericArgData` to construct `GenericArg` because it's less verbose and more readable.
