* fix(figma-api): size script text to its content, as Figma does figma.createText() made fixed 100px text at 14px, and the API never re-measured text, so scripts saw sizes Figma does not. New text is now empty 12px WIDTH_AND_HEIGHT text, one line tall; API updates re-measure auto-sizing text through the editor's textAutoResizeChanges; and resize() sets textAutoResize to NONE. Values were recorded in live Figma. * test(figma-api): hold recorded text sizes to the stated 1 px |

@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))
