Show placeholder while run command gets runnables from server
This PR fixes a UI annoyance in the VS Code extension when working in large codebases where rust-analyzer can take a few moments to interact with the server. Scenario:
1. Invoke "rust-analyzer: Run" from the command palette or hotkey
2. Quickly start typing to filter the list (or press Enter to accept the last runnable)
We often do this quickly from muscle memory without waiting to see the picker. The picker often takes several seconds to come up, causing us to type garbage into the currently open editor.
Fix:
Show a placeholder item before we call out to the server.
Selecting this item does nothing so if the user accidentally hits Enter nothing happens.
The list is populated and the placeholder dismissed when the actual runnables are retrieved. From here the behavior is the same as before.
Fix panic with closure inside array len
I was working on #15947 and found out that we panic on this test:
```
fn main() {
let x = [(); &(&'static: loop { |x| {}; }) as *const _ as usize]
}
```
This PR fixes the panic. Closures in array len are still broken, but closure in const eval is not stable anyway.
Fix WideChar offsets calculation in `line-index`
Fix#15981. This PR addresses the issue with the WideChar's offset calculation, ensuring accurate line-specific positions during text analysis in the `lib/line-index` module.
## Changes Made
- Corrected the calculation for `WideChar` offsets, ensuring they reflect positions within respective lines.
- Added tests to verify the accuracy of `WideChar` offset calculations, and correct existing tests.
make ParamLoweringMode accessible
In `hir-ty`, the `TyLoweringContext` has functions `pub fn with_impl_trait_mode` and `pub fn with_type_param_mode`, which can be used to fine-tune certain lowering properties.
Each of these takes one enum (either `pub enum ImplTraitLoweringMode`, or `pub enum ParamLoweringMode`), which encodes the possible configuration options.
To then make this usable for other crates, `TyLoweringContext` and `ImplTraitLoweringMode` are exported. Unfortuntely, `ParamLoweringMode` is not. This means that while the method can be called, there are no useful values to call it with.
Presumably this is an oversight. It would be great if this was made actually public.
feat: Allow navigation targets to be duplicated when the focus range lies in the macro definition site
Basically if a name of an item originates from the macro definition we now point to that as well as the creating macro call.
Big diff because I also made `FileId`s field private due to some debugging I had to do (having a searchable constructor makes things easier).
fix: Insert fn call parens only if the parens inserted around field name
Fixes#16014.
Sorry I missed it in previous PR. I've added a test as level to prevent regressions again.
Give any suggestions to improve the test if anything.
internal: Don't explicitly warn against `semicolon_in_expressions_from_macros`
This has been warn-by-default for two years now and has already been added to the future-incompat lints in 1.68.
See https://github.com/rust-lang/rust/issues/79813 for the tracking issue.
TokenMap -> SpanMap rewrite
Opening early so I can have an overview over the full diff more easily, still very unfinished and lots of work to be done.
The gist of what this PR does is move away from assigning IDs to tokens in arguments and expansions and instead gives the subtrees the text ranges they are sourced from (made relative to some item for incrementality). This means we now only have a single map per expension, opposed to map for expansion and arguments.
A few of the things that are not done yet (in arbitrary order):
- [x] generally clean up the current mess
- [x] proc-macros, have been completely ignored so far
- [x] syntax fixups, has been commented out for the time being needs to be rewritten on top of some marker SyntaxContextId
- [x] macro invocation syntax contexts are not properly passed around yet, so $crate hygiene does not work in all cases (but most)
- [x] builtin macros do not set spans properly, $crate basically does not work with them rn (which we use)
~~- [ ] remove all uses of dummy spans (or if that does not work, change the dummy entries for dummy spans so that tests will not silently pass due to havin a file id for the dummy file)~~
- [x] de-queryfy `macro_expand`, the sole caller of it is `parse_macro_expansion`, and both of these are lru-cached with the same limit so having it be a query is pointless
- [x] docs and more docs
- [x] fix eager macro spans and other stuff
- [x] simplify include! handling
- [x] Figure out how to undo the sudden `()` expression wrapping in expansions / alternatively prioritize getting invisible delimiters working again
- [x] Simplify InFile stuff and HirFIleId extensions
~~- [ ] span crate containing all the file ids, span stuff, ast ids. Then remove the dependency injection generics from tt and mbe~~
