PyDSDL

PyDSDL is a UAVCAN DSDL compiler front-end implemented in Python. It accepts a DSDL namespace at the input and produces a well-annotated abstract syntax tree (AST) at the output, evaluating all constant expressions in the process. All DSDL features defined in the UAVCAN Specification are supported. The library should, in theory, work on any platform and with any Python implementation.
