I am trying to update the [Nunavut](https://github.com/OpenCyphal/nunavut) Version inside of [Nunaweb](https://github.com/OpenCyphal/nunaweb) from 1.3.0 to the current 2.1.1 (see: [nunaserver/requirements.txt](https://github.com/OpenCyphal/nunaweb/blob/main/nunaserver/requirements.txt)).

Right now I have my difficulties with the implementation of the rewritten LanguageContextBuilder() (here: LanguageContext()) inside of the [generator.py](https://github.com/OpenCyphal/nunaweb/blob/main/nunaserver/nunaserver/generator.py) as it would probably require mingling with the code of Nunavut (such as the [init.py](https://github.com/OpenCyphal/nunavut/blob/main/src/nunavut/lang/ __init__.py)).

@scottdixon could you provide the documentation to the migration of Nunavut from 1.x.x to 2.x.x ?

Thank you in advance!

Sorry but there was no migration doc written. I’m not exactly sure what your difficulty is but you might try looking at the CLI runner ([nunavut/src/nunavut/cli/runners.py at main · OpenCyphal/nunavut · GitHub](https://github.com/OpenCyphal/nunavut/blob/main/src/nunavut/cli/runners.py)) since this is a high-level python integration that works directly with the generators given a set of input parameters. Perhaps we just need a more generic runner for nunaweb?
