470: Type inference for enum variants r=flodiebold a=marcusklaas
Opened a new PR instead of https://github.com/rust-analyzer/rust-analyzer/pull/461. Totally botched that one.
I think I resolved all the issues mentioned there.

478: WIP: implement cancelation via unwinding r=matklad a=matklad
This uses https://github.com/salsa-rs/salsa/pull/107 to implement cancellation.
Now we can get rid of `Cancelable` wrapper from everywhere except the top-level analyzer library.

442: WIP: indent on typing dot r=matklad a=simonvandel
Fixes#439.
The unit test passes, but I can't seem to make VS code perform the action. The existing action on "=" doesn't work either on my end either though.
I didn't add any smart way of detecting the current indent level. Any ideas how I would do that?

440: Implement type inference for boolean operators r=flodiebold a=marcusklaas
Tried implementing the easiest part of https://github.com/rust-analyzer/rust-analyzer/issues/390. Hope this is somewhat close to what the intent of the issue was. Found it surprisingly easy to find my way around the repository - it's well organized!
Very grateful for any pointers.

441: hir::Expr r=matklad a=flodiebold
Still a bit to do, but I already adapted `FnScopes` and thought I'd get feedback already.
Co-authored-by: Florian Diebold <flodiebold@gmail.com>
This was a bit complicated. I've added a wrapper type for now that does the
LocalSyntaxPtr <-> ExprId translation; we might want to get rid of that or give
it a nicer interface.
370: Self params & type r=matklad a=flodiebold
This implements type inference for `self`, so field completion for methods taking `self` works now.
- rename `IMPL_ITEM` to `IMPL_BLOCK` -- rustc calls the methods etc. inside an impl `ImplItem`s, and the impl itself doesn't define an item, so I thought this name was clearer.
- add HIR for impl blocks -- we collect all impls in a crate at once, so we can go from methods to containing impls, and since we will later also need to find all impls for a certain type (which may be anywhere in the crate, I think?). We could be more lazy here, but I don't know if it's worth the complexity.
- resolve `self` and `Self` during type inference
- refactor a bit in ty.rs as well
Co-authored-by: Florian Diebold <flodiebold@gmail.com>
Since we need to be able to go from def to containing impl block, as well as the
other direction, and to find all impls for a certain type, a design similar to
the one for modules, where we collect all impls for the whole crate and keep
them in an arena, seemed fitting. The ImplBlock type, which provides the public
interface, then consists only of an Arc to the arena containing all impls, and
the index into it.
406: Simplify r=matklad a=matklad

This will really become necessary when we implement generics, but even now, it
allows us to reason 'backwards' to infer types of expressions that we didn't
understand for some reason.
We use ena, the union-find implementation extracted from rustc, to keep track of
type variables.
350: Super simple macro support r=matklad a=matklad
Super simple support for macros, mostly for figuring out how to fit them into the current architecture. Expansion is hard-coded and string based (mid-term, we should try to copy-paste macro-by-example expander from rustc).
Ideally, we should handle
* highlighting inside the macro (done)
* extend selection inside the macro
* completion inside the macro
* indexing structs, produced by the macro

332: Struct types r=matklad a=flodiebold
Infer types for struct fields, and add basic field completions. There's also some code for enums, but I focused on getting structs working.
There's still ways to go before this becomes useful: There's no autoderef (or even reference types) and no inference for `self`, for example.

We need to be able to get the receiver even if there is no field name yet, and
currently "a." wouldn't get parsed as a field name at all. This seems to help.

327: Beginnings of type inference r=flodiebold a=flodiebold
I was a bit bored, so I thought I'd try to start implementing the type system and see how far I come 😉 This is obviously still extremely WIP, only very basic stuff working, but I thought I'd post this now to get some feedback as to whether this approach makes sense at all.
There's no user-visible effect yet, but the type inference has tests similar to the ones for the parser. My next step will probably be to implement struct types, after which this could probably be used to complete fields.
I realize this may all get thrown away when/if the compiler query system gets usable, but I feel like there are lots of IDE features that could be implemented with somewhat working type inference in the meantime 😄

306: Finish weird exprs r=DJMcNab a=DJMcNab
Fix#290.
Note that I'm not certain my use of `p.nth(1) == Ident` is entirely consistent with `libsyntax` - in the original, [`is_union_item`](9622f9dc47/src/libsyntax/parse/parser.rs (L4593-L4596)) uses `t.is_ident() && !t.is_reserved_ident()`, whereas we effectively only do `is_ident`. However, I cannot find the definition of `is_reserved_ident` (even searching the rust repository only gives uses, no definitions), so this will have to do unless someone else can find it :|.

273: Add a test to ensure that we can parse each file r=matklad a=DJMcNab

Co-authored-by: DJMcNab <36049421+djmcnab@users.noreply.github.com>
This fixes a common problem when running under VS Code, the user
doesn't have permissions to create a `log` directory in the CWD.
The old behavior can be re-enabled by setting RA_INTERNAL_MODE=1
The cast expression expected any type via types::type_() function,
but the language spec does only allow TypeNoBounds (types without direct extra bounds
via `+`).
**Example:**
```rust
fn test() {
6i8 as i32 + 5;
}
```
This fails, because the types::type_() function which should parse the type after the
as keyword is greedy, and takes all plus sign after path types as extra.
My proposed fix is to replace the not implemented `type_no_plus()` just calls (`type_()`)
function, which is used at several places. The replacement is `type_with_bounds_cond(p: &mut Parser, allow_bounds: bool)`, which passes the condition to relevant sub-parsers.
This function is then called by `type_()` and the new public `type_no_bounds()`.
271: Implement format hook r=matklad a=DJMcNab
Tentatively: fixes#155.
However, this does add all changes in staged files, which might not be desirable. However, I think we can't solve that without explicit support in rustfmt for it, so it should be fine.

"volatile" means "changes every time". That is, all transitive
rev-deps of volatile queries will be executed every time. We actually
need "dependencies".
Note that VSCode asks for completion after *first* `:` as well:
use crate:
we use hacks to protect against that, and to give completions only
after the second `:`.

167: Attempt to extract useful comments from function signatures r=matklad a=kjeremy
I'm trying to extract useful function comments for signature info. This will also be useful for hover. This is a WIP (and actually works pretty well!) but I don't think it's the right approach long term so some guidance would be appreciated so that we could also get comments for say types and variable instances etc.
Currently `test_fn_signature_with_simple_doc` fails due to a bug in `extend` but we probably shouldn't use this approach anyway. Maybe comments should be attached to nodes somehow? I'm also thinking that maybe the markdown bits should live in the language server.
Thoughts?

I went ahead and fixed all the clippy lints (there were a couple I thought would be better unfixed and added `cfg` statements to allow them) and also re-enabled clippy and rustfmt in CI.
They were disabled with `no time to explain, disable clippy checks`, so hopefully this won't go against whatever the reason at the time was 😆.
One question about the CI though: right now, it's an allowed failure that runs against the latest nightly each time. Would it be better to pin it to a specific nightly (or use the `beta` versions) to lower the churn?

Use this in the LSP to implement find all references and rename.

128: Add a test to verify if the generated codes are up-to-date. r=matklad a=mominul
This test checks if the generated codes are up-to-date every time during `cargo test`.
I have confirmed that the test works by manually editing the `grammar.ron` file.
Closes#126
Thanks!

127: Improve folding r=matklad a=aochagavia
I was messing around with adding support for multiline comments in folding and ended up changing a bunch of other things.
First of all, I am not convinced of folding groups of successive items. For instance, I don't see why it is worthwhile to be able to fold something like the following:
```rust
use foo;
use bar;
```
Furthermore, this causes problems if you want to fold a multiline import:
```rust
use foo::{
quux
};
use bar;
```
The problem is that now there are two possible folds at the same position: we could fold the first use or we could fold the import group. IMO, the only place where folding groups makes sense is when folding comments. Therefore I have **removed folding import groups in favor of folding multiline imports**.
Regarding folding comments, I made it a bit more robust by requiring that comments can only be folded if they have the same flavor. So if you have a bunch of `//` comments followed by `//!` comments, you will get two separate fold groups instead of a single one.
Finally, I rewrote the API in such a way that it should be trivial to add new folds. You only need to:
* Create a new FoldKind
* Add it to the `fold_kind` function that converts from `SyntaxKind` to `FoldKind`

Implements a pretty barebones function signature help mechanism in
the language server.
Users can use `Analysis::resolve_callback()` to get basic information
about a call site.
Fixes#102
116: Collapse comments upon join r=matklad a=aochagavia
Todo:
- [x] Write tests
- [x] Resolve fixmes
- [x] Implement `comment_start_length` using the parser
I left a bunch of questions as fixmes. Can someone take a look at them? Also, I would love to use the parser to calculate the length of the leading characters in a comment (`//`, `///`, `//!`, `/*`), so any hints are greatly appreciated.
