DeltaScript v1.0.3 – Release Notes

Highlights

Robust multi-error reporting across CLI and VS Code, no more “stop at first error.”
Accurate scope handling for class methods and control blocks, eliminating false “Redeclaration” errors.
Config quality-of-life: dsk.config.ds supports both plain objects and export default {}.
VS Code stability & hot-reload for the transpiler with ESM cache-busting.

Multi-error diagnostics:
- transpileSpark now returns { code, diagnostics } with all collected errors.
- Syntax errors are mapped back to original lines even when interfaces are stripped.
Scope system correctness:
- Detects methods with async/static/get/set/constructor.
- Supports multi-line headers (brace { on the next line).
- Conservative scope closing: only count } that start a line (ignores object/array closures like }, or }:).
- Parameters are registered in the correct function/method scope.
Typed arrays and interfaces:
- Precise inference for array literals, including interface-compatible arr<obj>.
- Shallow interface validation on object literals at declaration/assignment.
Object-only files auto-wrap:
- A file that is a single top-level object literal is auto-wrapped as export default { … }.
Emitted JS validation:
- Final pass parse with comment-stripping fallback; records any emitted JS syntax errors as diagnostics.

New transpiler contract supported:
- Properly consumes { code, diagnostics } from transpileSpark.
- Prints code-frames for all errors per file.
Build/dev experience:
- dsc init creates dsk.config.ds using export default { … }.
- dsk.config.ds is excluded from compilation/watch to avoid false syntax errors.
Spec helpers:
- Optional injection of SpectralLogs and console→spec rewrite preserved, now applied safely with the new output flow.

Flexible formats:
- Accepts both plain object and export default { … }.
- Strips comments, quotes keys, and parses as JSON internally.
- Defaults builtins: true when unspecified.

Language Server stability:
- ESM cache-busting (?t=timestamp) ensures the latest transpiler loads.
- Added a request handler to hot-reload the transpiler and revalidate open docs.
Multi-error surfaced in editor:
- The server now consumes and forwards all diagnostics from the transpiler.
Fewer false positives:
- Scope fixes and conservative closing rules ported to the bundled transpiler.
- Temporary filter suppresses noisy “Redeclaration … in the same scope” messages.
Config auto-wrap in editor:
- A file that is just { … } is treated as export default { … } to avoid syntax errors in the editor.

Fixed false “Redeclaration of variable 'scope' in the same scope” in methods and blocks.
Fixed incorrect scope closure on lines that contained object/array trailing braces.
Fixed extension loading stale transpiler due to ESM caching.
Fixed CLI crashes when transpiler returns structured diagnostics.
Fixed config parsing errors for plain object dsk.config.ds.

Scope handling now includes:
- Class method detection with async/static/get/set/constructor.
- Multi-line header handling with pending-open tracking.
- Per-line transactional error handling with conservative scope rollback (extension).
