Signature help now supports VS tooltip coloring (
f4a1d2a)
A large test-focused change adds coverage for colored signature help and JSDoc formatting in Visual Studio. This looks like editor UI groundwork for richer tooltip rendering across many signature-help and quick-info scenarios.
Fix CommonJS collisions with top-level Object (7ce364c)
The checker now reports a reserved-name collision when Object is declared in the top level of a CommonJS module. This closes a correctness gap that previously let generated CommonJS output shadow a global identifier without diagnostics.
Prevent JSX type instantiation crashes on non-interface types (ed52070) A guard was added so JSX default type-argument filling only runs for class/interface-like managed types. That avoids a SIGSEGV when JSX config points at unexpected type forms.
Fix --typeRoots relative-path panic on the CLI (4d18200)
Relative entries in array-valued path options are now normalized to absolute paths during command-line parsing. This prevents a parser crash and makes --typeRoots behave correctly when invoked from a project directory.
Break tsconfig extends cycles without deadlocking (16eae3f)
Extended config resolution now uses canonical path tracking and has explicit regression tests for self-references, mutual cycles, and case-insensitive filesystem collisions. The fix turns a hang into a normal circularity diagnostic.
Refresh project snapshots when files close (
a7acc87)
The project/session layer now updates snapshots and project state on file close. That should keep language-service state in sync after edits, reducing stale results in multi-file workflows.
Fix overlayfs save panics when no overlay exists (54617df) Saving through overlayfs no longer assumes an overlay layer is already present. This prevents a crash in a file-save path that should be routine.
Correct signature-help applicable spans for nested calls (e06d14e) Signature help now computes better applicable ranges for nested call expressions, with new fourslash coverage. That improves parameter highlighting and what the editor considers the active call site.
Stop regex parsing from hanging on invalid UTF-8 (9522325) The regexp scanner now consumes invalid UTF-8 bytes even under the Unicode flag, avoiding an infinite loop. This is a parser robustness fix for malformed source text.
Fix auto-import panics for relative CSS augmentations (6f58807)
Auto-import completion now handles .css module augmentations from ESM files without crashing, and the path helper was adjusted to stop stripping arbitrary file extensions. This should make CSS augmentation imports work reliably.
Improve workspace symbol name-span handling (
1170944)
Workspace symbol lookup now uses the declaration name span, with updated fourslash coverage and baselines across navigation/symbol tests. This improves symbol precision in the language service.
Accept CommonJS module.exports = {} baseline updates (401d27a)
Several declaration-emit baselines were moved from triaged to accepted for CommonJS-related output. This is mostly test maintenance around existing JS declaration behavior.
Fix using newline grammar handling (e5a356e)
The parser now respects the no-line-terminator restriction after using, with a regression test added. This closes a small grammar bug that could misparse invalid declarations.
Prevent tuple slicing from going out of bounds (2a876a5) Tuple type slicing now returns an empty tuple when the slice start is past the end. That avoids an out-of-range panic in conditional/infer tuple patterns.
Port the implement-interface quick fix (
3d2b680)
A substantial refactor ports the implement-interface code fix and updates the fourslash harness and many generated tests. This expands code-fix support, but most of the day’s volume here is test and infrastructure churn.
Other misc changes
- Fix global diagnostic test flake (
dd3d9c7) - Accept/move CommonJS declaration-emit baselines (401d27a)
- Test and harness updates for signature-help coloring, navigation, and code-fix coverage (f4a1d2a, 1170944, 3d2b680)
- Minor internal refactors and test adjustments across checker, project, and parsing code
