PLY Protobuf

[Protocol Buffers] 0 lexer & parser written in Python for [PLY] 1.

With this library you can create and process parse trees of a Protocol Buffers files with Python. For example usage see demo.py.

My use case: automated refactoring of .proto files.

Dependency

This project has only one dependency, [PLY] 1.
ply/ subdirectory is present in this repo for demonstration purposes and completeness only. If you intend to use this project, prefer better original [PLY] 1 repository which is up-to-date.

There may be bugs although it works for me for quite complicated protocol buffers files. If you find a bug, please feel free to submit a pull request or file an issue.

This work was inspired by:

This project was created because I needed it for myself and I didn't find Protocol Buffers parser for PLY. It is my first PLY / parser generator project and the first version was created in couple hours so it is not polished code.
There already exist Protocol Buffer parsing variant as [pyparsing] 3 example, but my previous scripts used PLY for parsing Java so I chosen to stay with PLY and to create Protocol Buffer variant for PLY. I like the output I can get from PLY (e.g., line, character position in the input text) so I can automatically process input files - e.g., refactoring.
API for this project is not guaranteed to remain stable. In particular I mean model generated from .proto files. Initial model may be considered suboptimal and changed at some point. This project is intended to serve as an inspiration or a starting point. You will probably adapt it for your own needs.
