Roadmap

Current Release ✅

✅ GDSII read/write (all 7 element types)
✅ OASIS read/write (all element types)
✅ Bidirectional format conversion
✅ Geometry: bounding box, transforms, area, point-in-polygon, fillet, fracture
✅ Boolean operations: union, intersection, difference, XOR, slice, offset, convex hull
✅ FlexPath with miter/bevel/round joins and configurable end caps
✅ Curve primitives: arc, Bezier, ellipse, spline, regular polygon, star, spiral
✅ Cell topology: flatten, dependency order, cycle detection, library merge
✅ Streaming parser for large files
✅ AREF expansion
✅ Property management
✅ CLI tool (convert, info, validate)
✅ File format detection by magic bytes
✅ 164 tests, zero external dependencies

Python bindings via PyO3 — drop-in replacement for gdstk
WebAssembly — browser-based layout tools
SIMD acceleration — vectorised coordinate operations
Parallel parsing — multi-threaded structure processing via Rayon (optional feature flag)
Design Rule Checking — basic geometric DRC (min width, spacing, overlap)
Layer mapping — transform layer numbers during conversion
Partial file reading — read a single named cell without parsing the whole file
GUI viewer — simple pan/zoom layout visualisation (egui)
