doc(alias)-based completion round 2
Follow-up on #14433
We can now complete fields, functions and some use/mods.
Flyimports don't behave, I don't really have the time to understand the structure there either.
While reading the flyimport code, I removed one method only used there, the closure-tree was a bit confusing, I can revert that if you want.
Add syntax::make::ty_alias
There was until now no function that returns TypeAlias. This commit introduces a func that is fully compliant with the Rust Reference. I had problems working with Ident so for now the function uses simple string manipulation until ast_from_text function is called. I am however open to any ideas that could replace ident param in such a way that it accepts syntax::ast::Ident
fix: Resolve `$crate` in derive paths
Paths in derive meta item list may contain any kind of paths, including those that start with `$crate` generated by macros. We need to take hygiene into account when we lower paths in the list.
This issue was identified while investigating #14607, though this patch doesn't fix the broken trait resolution.
mbe: fix token conversion for doc comments
fixes#14611
when creating token trees for the converted doc comment, we should use the correct span in all places, rather than allowing some to remain unspecified. otherwise, things behave incorrectly.
Simple fix for make::impl_trait
This is my first PR in this project. I made this PR because I needed this function to work properly for the main PR I am working on (#14386). This is a small amendment to what it was before. We still need to improve this in order for it to fully comply with its syntactic definition as stated [here](https://doc.rust-lang.org/reference/items/implementations.html).
Detect sysroot dependencies using symlink copy
cc #7637
It is currently in a proof of concept stage, and it doesn't generates a copy. You need to provide your own sysroot copy in `/tmp/ra-sysroot-hack` in a way that `/tmp/ra-sysroot-hack/library/std/lib.rs` exists and `/tmp/ra-sysroot-hack/Cargo.toml` is [the one from this comment](https://github.com/rust-lang/rust-analyzer/issues/7637#issuecomment-1495008329). I will add the symlink code if we decide that this approach is not a dead end.
It seems to somehow work on my system. Go to definition into std dependencies works, type checking can look through fields if I make them public and `cfg_if` appears to work (I tested it by hovering both sides and seeing that the correct one is enabled). Though finding layout of `HashMap` didn't work.
Please try it and let me know if I should go forward in this direction or not.
fix: `editor.parameterHints.enabled` not always being respected
#13472
When accepting a suggestion, the parameter hints would always trigger automatically. This PR provides the ability for users to toggle this functionality off by specifying the new "rust-analyzer.autoTriggerParameterHints" option in `settings.json`. Possible options are `true` and `false`. It's `true` by default.
