Manually testing with pyodide

We need to add pyodide to CI, but for now to manually run tests do the following:

Get current pyodide version

You will need to do this from the oso_semantic directory.

PYODIDE_EMSCRIPTEN_VERSION=$(pyodide config get emscripten_version)

Install emscripten

Choose a place to store the code and git clone emsdk:

cd some/base/directory
git clone https://github.com/emscripten-core/emsdk
cd emsdk

./emsdk install ${PYODIDE_EMSCRIPTEN_VERSION}
./emsdk activate ${PYODIDE_EMSCRIPTEN_VERSION}
source emsdk_env.sh

Build pyodide wheel

Now go back to the oso_semantic directory

cd oso/warehouse/oso_semantic
uv run pyodide build

This will generate a .whl file in dist

Download pyodide version

Download the recent pyodide version (at the time of writing is 0.27.2):

cd dist/
wget https://github.com/pyodide/pyodide/releases/download/0.27.2/pyodide-0.27.2.tar.bz2
tar xjf pyodide-0.27.2.tar.bz2

This will now have generated a dist/pyodide directory.

Run pytest

uv run pytest --run-in-pyodide . --runtime node --dist-dir=./dist
