4128: Include correct item path for variant completions r=matklad a=jonas-schievink
The test would previously suggest `E::V`, which is not enough to name the variant as the enum is in a module. Now it correctly suggests the full path `m::E::V`.

3998: Make add_function generate functions in other modules via qualified path r=matklad a=TimoFreiberg
Additional feature for #3639
- [x] Add tests for paths with more segments
- [x] Make generating the function in another file work
- [x] Add `pub` or `pub(crate)` to the generated function if it's generated in a different module
- [x] Make the assist jump to the edited file
- [x] Enable file support in the `check_assist` helper
4006: Syntax highlighting for format strings r=matklad a=ltentrup
I have an implementation for syntax highlighting for format string modifiers `{}`.
The first commit refactors the changes in #3826 into a separate struct.
The second commit implements the highlighting: first we check in a macro call whether the macro is a format macro from `std`. In this case, we remember the format string node. If we encounter this node during syntax highlighting, we check for the format modifiers `{}` using regular expressions.
There are a few places which I am not quite sure:
- Is the way I extract the macro names correct?
- Is the `HighlightTag::Attribute` suitable for highlighting the `{}`?
Let me know what you think, any feedback is welcome!

3954: Improve autocompletion by looking on the type and name r=matklad a=bnjjj
This tweet (https://twitter.com/tjholowaychuk/status/1248918374731714560) gaves me the idea to implement that in rust-analyzer.
Basically for this first example I made some examples when we are in a function call definition. I look on the parameter list to prioritize autocompletions for the same types and if it's the same type + the same name then it's displayed first in the completion list.
So here is a draft, first step to open a discussion and know what you think about the implementation. It works (cf tests) but maybe I can make a better implementation at some places. Be careful the code needs some refactoring to be better and concise.
PS: It was lot of fun writing this haha

4065: Complete unqualified enum names in patterns and expressions r=matklad a=nathanwhit
This PR implements the completion described in #4014.
The result looks like so for patterns:

and for `expr`s:

I'm not confident that the completion text itself is very robust, as it will unconditionally add completions for enum variants with the form `Enum::Variant`. This means (I believe) it would still suggest `Enum::Variant` even if the local name is changed i.e. `use Enum as Foo` or the variants are brought into scope such as through `use Enum::*`.

Detailed changes:
1) Implement a lexer for string literals that divides the string in format specifier `{}` including the format specifier modifier.
2) Adapt syntax highlighting to add ranges for the detected sequences.
3) Add a test case for the format string syntax highlighting.
This is a quick way to implement unresolved reference diagnostics.
For example, adding to VS Code config
"editor.tokenColorCustomizationsExperimental": {
"unresolvedReference": "#FF0000"
},
will highlight all unresolved refs in red.
4029: Fix various proc-macro bugs r=matklad a=edwin0cheng
This PRs does the following things:
1. Fixed#4001 by splitting `LIFETIME` lexer token to two mbe tokens. It is because rustc token stream expects `LIFETIME` as a combination of punct and ident, but RA `tt:TokenTree` treats it as a single `Ident` previously.
2. Fixed#4003, by skipping `proc-macro` for completion. It is because currently we don't have `AstNode` for `proc-macro`. We would need to redesign how to implement `HasSource` for `proc-macro`.
3. Fixed a bug how empty `TokenStream` merging in `proc-macro-srv` such that no L_DOLLAR and R_DOLLAR will be emitted accidentally.
