protoc-docs-plugin

This is a protoc plugin intended to augment protoc's default Python output with docstrings. It has been loosely designed to be able to support docstrings for other langauges also, but this is contingent upon the availability of appropriate insertion points in those languages.

Installation & Dependencies

This package depends on the current version of protobuf and pypandoc from PyPI.

$ pip install protoc-docs-plugin

Additionally, this package also depends on the pandoc OS package, which you will need to install from your OS package manager.

While it will run standalone as well, it only ever actually makes sense to invoke it from protoc.

Usage

Add --pydocstring_out to the same command to protoc that has a previous --python_out directive.

Example:

$ protoc foo.proto --python_out=. --pydocstring_out=.

Order does matter here; protoc must write the plain Python output first before it can augment it with the output from this plugin.
