There are two ways to build pyodide ifcopenshell Python wrapper wheel.

1. Using pyodide build system (build_pyodide.yml does it):

• install prebuilt pyodide build and emscripten environment (see build_pyodide.sh)
• clone IfcOpenShell to IfcOpenShell folder
• create packages/ifcopenshell folder that will be used by pyodide build system
• from IfcOpenShell move building recipe pyodide/meta.yaml to packages/ifcopenshell
• run pyodide build-recipes ifcopenshell --install, it will
  • execute meta.yaml recipe - it will:
    • copy IfcOpenShell source to build folder packages/ifcopenhell/build/ifcopenshell-0.8.0
    • build ifcopenshell and its dependencies
    • note that rerunning pyodide build-recipes will remove previous build folder and rebuild all dependencies.
      The way to avoid it, if build fails, is to use pyodide build-recipes-no-deps ifcopenshell --continue instead.
  • run setup.py in IfcOpenShell root, producing a wheel in IfcOpenShell/dist
  • copy that wheel to packages/ifcopenshell/dist
  • --install it to current build envrionment
    • copy the wheel next to dist folder (in root directory, next to packages)
    • add wheel to dist/pyodide-lock.json

2. Build it outside of pyodide build system.

Building inside pyodide build system should be preferred, option to build it outside is useful for debugging purposes, since it's pure cmake without any additional moving parts.

• setup pyodide environment, see above
• clone IfcOpenShell repo next to it to IfcOpenShell folder
• run python nix/build-all.py -wasm -py-313 in IfcOpenShell
  • it will produce Python package in IfcOpenShell/ifcopenshell
• run pyodide build
  • it will produce a wheel in IfcOpenShell/dist
