The behaviour tests used property IDs that may be null as references and read a parsed .fig buffer and the node iterable as arrays, so bun run check failed on master. CI does not run the test typecheck. |

@open-pencil/core
Editor engine for OpenPencil: the CanvasKit (Skia WASM) renderer, Yoga layout, the framework-agnostic editor with undo and selection, the Figma Plugin API compatibility layer, the AI/MCP tool definitions, clipboard and vector conversion, and format-neutral document I/O.
It depends on @open-pencil/scene-graph, @open-pencil/pen, @open-pencil/kiwi, and @open-pencil/fig, and keeps browser DOM out so it runs in the app, the CLI, the MCP server, and headless scripts alike.
Import the root barrel or the targeted subpaths listed in package.json exports, for example @open-pencil/core/io, @open-pencil/core/geometry, and @open-pencil/core/canvaskit.
Scripts get two globals through compileScript from @open-pencil/core/tools: figma, the Figma Plugin API over a document, and openpencil (OpenPencilAPI from @open-pencil/core/openpencil-api), what OpenPencil adds to it in the same style, such as making a component behave as a Reka UI control:
import { FigmaAPI } from '@open-pencil/core/figma-api'
import { compileScript } from '@open-pencil/core/tools'
await compileScript(`
const set = figma.currentPage.findOne((n) => n.name === 'Switch')
openpencil.setBehaviour(set, { kind: 'switch', values: { value: 'State' } })
`)(new FigmaAPI(graph))
