Tooling to generate bindings for multiple languages

[marko]

Hi,

I'm trying out Protocol buffers and would be interested in learning

what kind of tooling more experienced Protobuf users are using

to generate code for multiple languages (Java, Python, C++),

compiling language bindings and publishing the bindings in an artifact repository.

thanks!

Hi, take a look at the "Other Languages"-Section in the protobuf docs. There is also a list of examples.

Basically you can extend protoc with your plugin by writing a binary that reads a CodeGeneratorRequest (protobuf-message) via standard-in and print a CodeGeneratorResponse (also protobuf-message) to standardout.

The CodeGeneratorRequest already has a lot of information interpreted, you "just" need to read it and convert it into code. So you use a language that already has a protobuf-compiler to compile your own protoc-plugin (for extending functionality or compiling your own classes).
