Fix the case where if a user types `&&42.o`, snippet completion
was still applying &&Ok(42). Note this was fixed previously
on `&&42.` but this still remained a problem for this case
feat: Autocomplete Cargo-defined env vars in `env!` and `option_env!` (#12448)
Closes#12448
Important to know:
- Variables are taken from https://doc.rust-lang.org/cargo/reference/environment-variables.html and hardcoded as a const array.
- For the sake of simplicity I didn't include the autocompletion of `CARGO_BIN_EXE_<name>` and `OUT_DIR` since it would require information about build.rs and binary name. If somebody knows an easy way of obtaining them I can add those vars as well :)
Refactor completions expansion
Depends on https://github.com/rust-lang/rust-analyzer/pull/13384
Diff is unfortunately massive as I changed the functions in the analysis module from associated ones to standalone (unfortunately without an extra commit)
Restructure `find_path` into a separate functions for modules and non-module items
Follow up to https://github.com/rust-lang/rust-analyzer/pull/13212
Also renames `prefer_core` imports config to `prefer_no_std` and changes the behavior of no_std path searching by preferring `core` paths `over` alloc
This PR turned into a slight rewrite, so it unfortunately does a few more things that I initially planned to (including a bug fix for enum variant paths)
New assist: move_format_string_arg
The name might need some improving.
```rust
fn main() {
print!("{x + 1}");
}
```
to
```rust
fn main() {
print!("{}"$0, x + 1);
}
```
fixes#13180
ref to #5988 for similar work
* extracted `format_like`'s parser to it's own module in `ide-db`
* reworked the parser's API to be more direct
* added assist to extract expressions in format args
