And implement addons as necessary.
There are many more makers to be moved, and I'm not completely satisfied with this (due to the ease of making a mistake in the AST structure, and slightly less but also because of the need to remember whitespaces), but this is already enough to see how this will look like.
I'm fairly sure this is more correct, and saves space(~90mb to 82mb
for Zed's index). I'm checking in about this with SCIP folks in
https://github.com/sourcegraph/scip/pull/299.
Before this change `SymbolInformation` provided by a document was the
info for all encountered symbols that have not yet been emitted. So,
the symbol information on a `Document` was a mishmash of symbols
defined in the documents, symbols from other documents, and external
symbols.
After this change, the `SymbolInformation` on documents is just the
locals and defined symbols from the document. All symbols referenced
and not from emitted documents are included in `external_symbols`.
In particular, the symbol generation before this change creates a lot
of symbols with the same name for different definitions. This change
makes progress on symbol uniqueness, but does not fix a couple cases
where it was unclear to me how to fix (see TODOs in `scip.rs`)
Behavior changes:
* `scip` command now reports symbol information omitted due to symbol
collisions. Iterating with this on a large codebase (Zed!) resulted in
the other improvements in this change.
* Generally fixes providing the path to nested definitions in
symbols. Instead of having special cases for a couple limited cases of
nesting, implements `Definition::enclosing_definition` and uses this
to walk definitions.
* Parameter variables are now treated like locals.
- This fixes a bug where closure captures also received symbols
scoped to the containing function. To bring back parameter
symbols I would want a way to filter these out, since they can
cause symbol collisions.
- Having symbols for them seems to be intentional in
27e2eea54f, but no particular use is
specified there. For the typical indexing purposes of SCIP I don't see
why parameter symbols are useful or sensible, as function parameters
are not referencable by anything but position. I can imagine they
might be useful in representing diagnostics or something.
* Inherent impls are now represented as `impl#[SelfType]` - a type
named `impl` which takes a single type parameter.
* Trait impls are now represented as `impl#[SelfType][TraitType]` - a
type named `impl` which takes two type parameters.
* Associated types in traits and impls are now treated like types
instead of type parameters, and so are now suffixed with `#` instead
of wrapped with `[]`. Treating them as type parameters seems to have
been intentional in 73d9c77f2a but it
doesn't make sense to me, so changing it.
* Static variables are now treated as terms instead of `Meta`, and so
receive `.` suffix instead of `:`.
* Attributes are now treated as `Meta` instead of `Macro`, and so
receive `:` suffix instead of `!`.
* `enclosing_symbol` is now provided for labels and generic params,
which are local symbols.
* Fixes a bug where presence of `'` causes a descriptor name to get
double wrapped in backticks, since both `fn new_descriptor` and
`scip::symbol::format_symbol` have logic for wrapping in
backticks. Solution is to simply delete the redundant logic.
* Deletes a couple tests in moniker.rs because the cases are
adequeately covered in scip.rs and the format for identifiers used in
moniker.rs is clunky with the new representation for trait impls
Because it was a mess.
Previously, pretty much you had to handle all path diagnostics manually: remember to check for them and handle them. Now, we wrap the resolver in `TyLoweringContext` and ensure proper error reporting.
This means that you don't have to worry about them: most of the things are handled automatically, and things that cannot will create a compile-time error (forcing you top `drop(ty_lowering_context);`) if forgotten, instead of silently dropping the diagnostics.
The real place for error reporting is in the hir-def resolver, because there are other things resolving, both in hir-ty and in hir-def, and they all need to ensure proper diagnostics. But this is a good start, and future compatible.
This commit also ensures proper path diagnostics for value/pattern paths, which is why it's marked "feat".
For Windows, this removes the need to add a breakpoint and modify a value to exit the debugger wait loop.
As a ridealong, this adds a 100ms sleep for all platforms such that waiting for the debugger doesn't hog the CPU thread.
