Add fixups for incomplete in proc-macros
Partially implements https://github.com/rust-lang/rust-analyzer/issues/12777.
Added support for for loops and match statements.
I couldn't do paths like `crate::foo::` as I wasn't able to add `SyntheticTokens` to the end of `foo::`, they always ended up after `crate::`
This is my first contribution so please don't be shy about letting me know if I've done anything wrong!
fix: make `concat!` work with char
Fixes#12921
- I avoided making `unquote_str()` take char literals as well because it's depended on by another function `parse_string()` that's only supposed to take strings.
- Even with this patch, we don't output `\0` as `\u{0}` which #12921 pointed out ~~, but we're not actually responsible for serializing it but rowan is~~. They are functionally equivalent and I don't think it'd cause any confusion, but we *could* try escaping them before serialization (for reference, `rustc -Zunpretty=expanded`, which `cargo expand` uses under the hood, [makes use of `str::escape_default()`](3830ecaa8d/compiler/rustc_ast/src/util/literal.rs (L161)).
- allow appending tokens after a token, not just a node
- allow inserting delimiters (and remove them again)
- fix up `if {}` and `if` without anything following
Distinguish between
- there is no build data (for some reason?)
- there is build data, but the cargo package didn't build a proc macro dylib
- there is a proc macro dylib, but it didn't contain the proc macro we expected
- the name did not resolve to any macro (this is now an
unresolved_macro_call even for attributes)
I changed the handling of disabled attribute macro expansion to
immediately ignore the macro and report an unresolved_proc_macro,
because otherwise they would now result in loud unresolved_macro_call
errors. I hope this doesn't break anything.
Also try to improve error ranges for unresolved_macro_call / macro_error
by reusing the code for unresolved_proc_macro. It's not perfect but
probably better than before.
Config revamp
Fixes https://github.com/rust-lang/rust-analyzer/issues/11790
Fixes https://github.com/rust-lang/rust-analyzer/issues/12115
This PR changes a lot of config names, and a few ones are being merged or split apart. The reason for this is that our configuration names currently are rather inconsistent and some where poorly chosen in regards to extensability. This PR plans to fix that.
We still allow the old config names by patching them to the new ones before deserializing to keep backwards compatability with other clients (the VSCode client will auto update the config) but ideally we will get rid of that layer in the future.
Here is a list of the changes:
These are simple renames `old_name | alias1 | alias2 ... -> new_name` (the vscode client will fix these up automagically):
