997: Improve filtering of file roots r=matklad a=vipentti
`ProjectWorkspace::to_roots` now returns a new `ProjectRoot` which contains
information regarding whether or not the given path is part of the current
workspace or an external dependency. This information can then be used in
`ra_batch` and `ra_lsp_server` to implement more advanced filtering. This allows
us to filter some unnecessary folders from external dependencies such as tests,
examples and benches.
Relates to discussion in #869

996: Allow attributes on top level expressions r=matklad a=pcpthm
This PR modifies parser to allow outer attributes on top level expression. Here, top level expression means either
- Expression statement e.g. `foo();`
- Last expression in a block without semicolon `bar()` in `{ foo(); bar() }`.
Except for binary operation expressions and `if` expressions, which are errors (feature gated) in rustc.
Attributes on inner expressions like `foo(#[a] 1)` are not implemented.
I first tried to implement this by passing `Maker` to expression parsers. However, this implementation couldn't parse `#[attr] foo()` correctly as `CallExpr(Attr(..), PathExpr(..), ArgList(..))` and instead parsed incorrectly as `CallExpr(PathExpr(Attr(..), ..), ArgList(..))` due to the way left recursion is handled.
In the end, I introduce `undo_completion` method. Which is not the suggested approach, but it seems not very bad.
Fix#759.

993: Fix installing vscode extension on MacOS r=matklad a=funkill
VSCode often installed in MacOS as `Visual Studio Code.app` package and `code` binary located at `Contents/Resources/app/bin` in package. This path not exists in `$PATH` variable and we can't run `code`.
In previous version of `do_run` function all before space was command and all after - arguments. If path or command has spaces, extracting command breaks. To fix this i extracted command to separated argument of function.
All packages can be placed in system app dir (`/Applications`) or user app dir (`~/Applications`). I created helper function for find app in this directories.

991: Use Marker argument for item parsers r=matklad a=pcpthm
Before doing this for expressions, I found that the pattern (Marker argument) should be applied to the item parsers because visiblity and modifiers are parsed in a separate function.
Fixed some parser bugs:
- Fix pub_expr: `pub 42;` was allowed.
- Fix incorrect parsing of crate::path: incorrectly parsed as `crate` as a visibility.

989: Implement naive version of fill_struct_fields assist r=matklad a=yanchith
Fixes#964
This implements the `fill_struct_fields` assist. Currently only works for named struct fields, but not for tuple structs, because we seem to be missing a `TupleStructLit` (akin to `StructLit`, but for tuple structs). I am happy to implement `TupleStructLit` parsing given some guidance (provided it's really missing) and make the assist work for tuple structs as well. Could do so either in this PR, or another one 🙂
Sorry if I missed something important, this is my first PR for Rust Analyzer.
Btw is there any way to run the assists in emacs?
UPDATE: I just realized that parsing `TupleStructLit` would be quite difficult as it it really similar, if not identical to a function call...

987: Refactor maybe_item to use Marker argument r=pcpthm a=pcpthm
As suggested at <https://github.com/rust-analyzer/rust-analyzer/pull/980#issuecomment-473659745>.
For expression paring functions, changing signature
- from `fn(&mut Parser) -> Option<CompletedMarker>` to `fn(&mut Parser, Marker) -> Result<CompletedMarker, Marker>`
- from `fn(&mut Parser) -> CompletedMarker` to `fn(&mut Parser, Marker) -> CompletedMarker`
is my plan.

983: support remainder assignment operator r=matklad a=JeanMertz
`%=` was returning errors for me, turns out it wasn't added as a valid assignment operation.
I'm not sure what the best location would be to add a test for this. Please let me know and I'll add one.

Asymptotically computing a set difference is faster but in the average
case we won't have more than ~10 functions. Also prefer not using hash
sets as these may yield nondeterministic results.
Implement `BindingMode` for pattern matching, so that types can be
correctly inferred using match ergonomics. The binding mode defaults to
`Move` (referred to as 'BindingMode::BindByValue` in rustc), and is
updated by automatic dereferencing of the value being matched.
If the client doesn't specify this explicitly, that very likely means it doesn't
know about it and so we shouldn't send decorations. In particular, the recent
change to this default caused decorations to be sent to emacs, resulting in a
lot of warning spam.
948: Fix test_missing_module_code_action_in_json_project on Windows r=matklad a=vipentti

933: Check installed extension r=matklad a=c410-f3r

Edit: Windows encoding for Unicode is UTF-16 so String::from_utf8 will probably fail unless `Vec<u8>` is already UTF-8 somehow, which I don't know for sure.

This allows users to control whether or not they want to see the "workspace
loaded" notification.
This is done on the server side using InitializationOptions which are provided
by the client. By default show_workspace_loaded is true, meaning the
notification is sent.
This now allows us to send a notification that can be shown in the UI when the
workspace has been loaded.
Additionally this removes the need for internal_mode flag.

We simply remove all the CUSTOM_MARKERS before attempting to parse the file.
This allows for the syntax selection to work with most of the test strings.
This allows us to select a string or portions of it and try parsing it as rust
syntax. This is mostly helpful when developing tests where the test
itself contains some rust syntax as a string.

This trait should be implemented for nodes which have an ascribed type,

In addition, we update some places where previously we used node + node.type_ref() with `TypeAscriptionOwner` in the trait bounds.

vscode would report "A request has failed" when it got "Content modified"
message and this would cause a pop-up to appear. This works around the issue by
returning an "empty" response that vscode can ignore.
This replaces places where we would use node + node.type_ref() with things that
have an ascribed type, with using the TypeAscriptionOwner as the trait bound so
we can simply pass the node.
