* More principled approach for finding From traitAleksey Kladov2020-04-293-37/+94

* Use specific pattern when translating if-let-else to matchAleksey Kladov2020-04-294-20/+123
| | | | | | We *probably* should actually use the same machinery here, as we do for fill match arms, but just special-casing options and results seems to be a good first step.

* Fix panic in split_imports assistAleksey Kladov2020-04-201-1/+6
| | | | | | | | | | | | | | | The fix is admittedly quit literally just papering over. Long-term, I see two more principled approaches: * we switch to a fully tree-based impl, without parse . to_string step; with this approach, there shouldn't be any panics. The results might be nonsensical, but so was the original input. * we preserve the invariant that re-parsing constructed node is an identity, and make all the `make_xxx` method return an `Option`. closes #4044

* Fix double comma when merge imports on second lineIceSentry2020-04-131-3/+37
| | | | | | | | | | | This fixes the a bug when merging imports from the second line when it already has a comma it would previously insert a comma. There's probably a better way to check for a COMMA. This also ends up with a weird indentation, but rust-fmt can easily deal with it so I'm not sure how to resolve that. Closes #3832

|\ | | | | | | | | | | | | | | | | | | 3925: Implement assist "Reorder field names" r=matklad a=geoffreycopin This PR implements the "Reorder record fields" assist as discussed in issue #3821 . Adding a `RecordFieldPat` variant to the `Pat` enum seemed like the easiest way to handle the `RecordPat` children as a single sequence of elements, maybe there is a better way ?

| | | | | | | | | | | | | | | | | | | | | | | | todo!() "Indicates unfinished code" (https://doc.rust-lang.org/std/macro.todo.html) Rust documentation provides further clarification: > The difference between unimplemented! and todo! is that while todo! > conveys an intent of implementing the functionality later and the > message is "not yet implemented", unimplemented! makes no such claims. todo!() seems more appropriate for assists that insert missing impls.

Issues to handle in another PR: - function reference arguments: Their type isn't printed properly right now. The "insert explicit type" assist has the same issue and this is probably a relatively rare usecase. - generating proper names for all kinds of argument expressions (if, loop, ...?) Without this, it's totally possible for the assist to generate invalid argument names. I think the assist it's already helpful enough to be shipped as it is, at least for me the main usecase involves passing in named references. Besides, the Rust tooling ecosystem is immature enough that some janky behaviour in a new assist probably won't scare anyone off. - select the generated placeholder body so it's a bit easier to overwrite it - create method (`self.foo<|>(..)` or `some_foo.foo<|>(..)`) instead of create_function. The main difference would be finding (or creating) the impl block and inserting the `self` argument correctly - more specific default arg names for literals. So far, every generated argument whose name can't be taken from the call site is called `arg` (with a number suffix if necessary). - creating functions in another module of the same crate. E.g. when typing `some_mod::foo<|>(...)` when in `lib.rs`, I'd want to have `foo` generated in `some_mod.rs` and jump there. Issues: the mod could exist in `some_mod.rs`, in `lib.rs` as `mod some_mod`, or inside another mod but be imported via `use other_mod::some_mod`. - refer to arguments of the generated function with a qualified path if the types aren't imported yet (alternative: run autoimport. i think starting with a qualified path is cleaner and there's already an assist to replace a qualified path with an import and an unqualified path) - add type arguments of the arguments to the generated function - Autocomplete functions with information from unresolved calls (see https://github.com/rust-analyzer/rust-analyzer/pull/3746#issuecomment-605281323) Issues: see https://github.com/rust-analyzer/rust-analyzer/pull/3746#issuecomment-605282542. The unresolved call could be anywhere. But just offering this autocompletion for unresolved calls in the same module would already be cool. Co-authored-by: Timo Freiberg <[email protected]>

|\ \ | |/ |/| | | | | | | | | | | | | | | 3814: Add impl From for enum variant assist r=flodiebold a=mattyhall Basically adds a From impl for tuple enum variants with one field. It was recommended to me on the zulip to maybe try using the trait solver, but I had trouble with that as, although it could resolve the trait impl, it couldn't resolve the variable unambiguously in real use. I'm also unsure of how it would work if there were already multiple From impls to resolve - I can't see a way we could get more than one solution to my query.

| | | | | | | | | | | | Basically adds a From impl for tuple enum variants with one field. Added to cover the fairly common case of implementing your own Error that can be created from another one, although other use cases exist.
