2ee87889faA board-level graphic text (Place→Text) lands in Drawings() and would otherwise hit the same asyncify-fragile (kicad_pcb …) envelope-blob wall as via/zone on add. So PCB_TEXT reconstructs NATIVELY: itemToJson emits size/thickness/angle plus horizontal & vertical justification, mirror, and bold/italic (the text string was already emitted for any EDA_TEXT); makeItem builds a fresh PCB_TEXT and restores all of them. flushDiff skips the blob for PCB_TEXT_T. Footprint child text is unaffected — it syncs by move, and its add is carried by the footprint blob. Justification matters: it anchors the glyphs relative to the text POSITION, so without it a left-justified text reconstructed centered on the peer and rendered visibly offset even though GetPosition() matched (which is why the anchor-only headless check missed it). Verified two-tab in the real app: a left/bottom-justified bold text added in tab A reconstructs in tab B at the exact position with matching justification + string. Headless: a board-text round-trip add test (sample text is left/bottom-justified) asserts the position AND that hjust/vjust/text round-trip. 7 passed, 1 skipped, 0 aborts.

KiCad WebAssembly Port
Run KiCad PCBnew in the browser using WebAssembly.
Quick Start
Full Build (KiCad + All Tests)
# 1. Initialize submodules
git submodule update --init --recursive
# 2. Build KiCad WASM (Docker, ~10 min incremental, ~1-2 hours full)
./docker/build.sh
# 3. Build wxWidgets for local testing
./scripts/build-wxuniversal-wasm.sh
# 4. Build wxWidgets test apps
./scripts/build-wasm-test.sh
# 5. Run all tests
cd tests && npm install
npm test # wxWidgets tests (256 tests)
npm run test:kicad # KiCad tests (2 tests)
wxWidgets Only (No Docker)
# Requires: Node.js 18+ (Emscripten SDK auto-installed on first build)
./scripts/build-wxuniversal-wasm.sh
./scripts/build-wasm-test.sh
cd tests && npm install && npm test

Feature Branches
Curated design docs and research notes for each feature live in
docs/features/<branch-name>/ (committed).
./scripts/create-feature-patches.sh [branch-name] generates per-branch patches
(root.patch, kicad.patch, wxwidgets.patch) into a local features/<branch-name>/
scratch dir. That dir is gitignored — the patches are local history, not committed.
Two Build Workflows
1. KiCad Build (Docker)
Full KiCad PCBnew build using Docker:
# Build KiCad WASM
./docker/build.sh
# Copy output to test directory
./tests/scripts/setup-kicad-wasm.sh
# Run KiCad tests
cd tests && npm install && npm run test:kicad
Output: output/pcbnew.js, output/pcbnew.wasm
See docs/build.md for detailed build documentation.
2. wxWidgets Test Apps (Local)
Build standalone wxWidgets test apps for feature testing:
# Build wxWidgets for WASM
./scripts/build-wxuniversal-wasm.sh
# Build test apps
./scripts/build-wasm-test.sh
# Run wxWidgets tests
cd tests && npm install && npm test
Output: tests/apps/standalone/
Prerequisites
For KiCad Build (Docker)
- Docker Desktop with 16GB+ RAM allocated
- 10+ GB disk space for build cache
For wxWidgets Build (Local)
- Node.js 18+ (for tests)
- Emscripten SDK (auto-installed on first build)
# Initialize submodules
git submodule update --init --recursive
# Install Emscripten SDK (auto-runs on first build, or run manually)
./scripts/setup-emsdk.sh
Testing
cd tests
npm install
# Run all tests
npm test
# Run specific tests
npm run test:kicad # KiCad tests only
npx playwright test menu # Menu tests only
See tests/README.md for test documentation.
Current Status
- wxWidgets WASM: Core widgets working (menus, dialogs, grids, trees, OpenGL)
- KiCad PCBnew: Builds and loads in browser, canvas rendering working
- In Progress: Testing wxWidgets features used by KiCad
