Still only on a feature branch, but over the past few days I've been working on updating https://thi.ng/geom to add support for polygons with holes and paths with holes (or more generally support for sub-paths, e.g. multiple curves). Since both of these shape types are containers of multiple geometries and therefore require in some situations (e.g. shape conversions) different handling than the other shapes with a single boundary/geometry, adding support for these also includes updating a dozen or so polymorphic shape operators/functions and unfortunately will involve a few of breaking changes. For instance, some of these functions are returning an array of shapes now, instead of just a single one. Also related, some of the other geom support packages (e.g. https://thi.ng/geom-axidraw, https://thi.ng/geom-sdf) will have to be refactored more and partially have been already (likely only internally, though)...
As part of this work, I've also just added example #160(!!!) to demonstrate & test out some of this new functionality:
