Danila Poyarkov 6a9b69f677 fix: keep bound text and visibility in step with their variables (#954 ) * fix: keep bound text and visibility in step with their variables Text bound to a string variable was resolved only when a .fig file was read, and visibility bound to a boolean never, so editing the value or switching a mode left them showing the old one. The binding reconcile, renamed reconcileVariableBindings, now resolves text and visibility with numbers, scoped the same way, and .fig export writes them resolved in each collection's default mode. A bound font family is left as stored, since changing it needs the font loaded. * fix: keep text and visibility an instance overrides over their bindings Typing in a bound layer inside an instance or toggling its eye records an override but keeps the binding, so the next value edit or mode switch replaced what was typed or hidden. An overridden text or visibility now keeps its value, as an overridden width or height does.		2026-10-07 18:37:15 +00:00

@open-pencil/fig

.fig file-format package for OpenPencil.

The package owns the outer .fig archive boundary and is the staged home for Figma-specific SceneGraph conversion policy. Production SceneGraph read/write remains available through @open-pencil/core/io while conversion modules move behind this package's public API.

Current ownership:

Complete .fig archive parsing through parseFigBuffer()
.fig archive assembly through writeFigArchive()
Canvas payload and image resource handling
readFigContainer() / writeFigContainer() helpers for raw fig-kiwi payloads
.fig source and archive result types
NodeChange-to-SceneGraph property conversion, including styles, plugin metadata, text, paint, vector, and font policy, through @open-pencil/fig/node-change
Component-property, symbol-override, derived-symbol-data, and instance synchronization policy through @open-pencil/fig/instance-overrides
Effective raw-metadata precedence and invalidation over SceneGraph's format-neutral edited-field tracking
SceneGraph-to-NodeChange export conversion with an explicit text-shaping runtime service for saved glyphs
Package-local archive, conversion, instance, export, and dist smoke tests

Architecture documentation

Start with the package docs for the source model, instance evaluation, materialization, document sessions, export, and validation contracts.

Planned ownership:

Oracle-backed .fig fixtures

Non-goals:

Generic Kiwi schema/runtime internals — use @open-pencil/kiwi
Format-neutral IO registration, export targeting, CanvasKit thumbnails, or browser workers — use @open-pencil/core/io
Editor actions, renderer behavior, Vue/app UI, CLI formatting, or MCP transport

This follows the existing @open-pencil/pen pattern: a format package owns its source model/parser and SceneGraph policy, while core registers it in the shared IO system.
