protoc-gen-py
The code generator plugin for Protocol Buffers for Python. Learn more about the project at github.com/bufbuild/protobuf-py.
Installation
protoc-gen-py generates base types—messages and enumerations—from your Protocol Buffer schema. The generated code requires the runtime library protobuf-py. It's compatible with Protocol Buffer compilers like buf and protoc.
To install the runtime library and the plugin, run:
$ uv add protobuf-py protoc-gen-py buf-bin
Generating code
With buf
Add a new buf.gen.yaml configuration file:
version: v2
inputs:
- directory: proto
plugins:
# This will invoke protoc-gen-py and write output to src/gen
- local: protoc-gen-py
out: src/gen
To generate code for all Protobuf files within your project, run:
$ uv run -- buf generate
Note that buf can generate from various inputs, not just local Protobuf files.
With protoc
$ uv run protoc --proto_path proto \
--py_out src/gen \
proto/a.proto proto/b.proto proto/c.proto
Plugin options
init_files
By default, the plugin creates __init__.py files in every directory of the generated output.
Set init_files=false to suppress this and produce namespace packages instead. Namespace packages allow multiple distribution packages to include modules under the same top-level package.
For example, in buf.gen.yaml:
plugins:
- local: protoc-gen-py
out: src/gen
opt: init_files=false
