Developing internal tools for multi-lingual teams
summary
Bumble builds matching internal R and Python packages that share foundations: implement R generics and Python functools.singledispatch for identical APIs; create named errors with rlang::abort and mirror Python exception classes so both sides can catch specific failures and chain causes (raise … from / abort(..., parent=cond)); wrap cross-language code with reticulate (import, source_python, onLoad delay) and rpy2 (STAP, object conversion), noting environment, conversion and error-message gotchas.
