WireViz translation Worker
This unit vendors the pristine yuzutech/ v0.3.3 release tag. The tag
uses commit 837d5425e72aa002bbe9cc60604dfeffab86d29c. Its runtime version remains
0.3.2. The unit stops after the upstream parser and model produce GraphViz DOT.
It sends the DOT through the GRAPHVIZ service binding to the shared
GraphViz-Wasm Worker.
License scope
The vendored WireViz implementation is GPL-3.0-only. This Worker imports and executes that implementation in the same Python program, so the deployable WireViz unit is distributed as a GPL-3.0-only combined work. DiagramZip code outside this unit remains under its own applicable license. The HTTP service binding to the separately deployed GraphViz Worker does not place that Worker inside this combined Python program.
The complete unit source is this directory, including src/, pyproject.toml,
uv.lock, pylock.toml, wrangler.jsonc, and the build/deployment commands
below. The full GPL text and exact upstream revision are recorded in
vendor-licenses/ and THIRD_PARTY_NOTICES.md.
The Python graphviz package and external dot executable are intentionally absent. src/ is the small DOT-builder interface required by WireViz.
The edge contract supports SVG only. Filesystem/remote images, tweak.append, and tweak.override are rejected. BOM and HTML sidecars are not part of the rendering contract.
Run the local and Pyodide packaging checks from this directory:
uv sync
uv run pytest -q
uv run pywrangler sync
uv run pywrangler deploy --dry-run
For an end-to-end local test, run the graphviz-family Wrangler dev server and
this Worker in separate terminals. Wrangler resolves the service binding by
Worker name and must report env.GRAPHVIZ ... local [connected]. Structural
coverage, not pixel equality, is the migration gate.
The request parser caps bodies at 1 MiB and sources at 512 KiB. It also limits YAML nesting, expanded nodes, components, pins, wires, connections, and numeric ranges. YAML anchors and merge templates remain supported within those bounds. Recursive aliases are rejected before the upstream model runs.
