setuptools-betterproto 0.3.0

A modern setuptools plugin to generate Python files from proto files using betterproto

Betterproto Setuptools plugin

Introduction

A modern setuptools plugin to generate Python files from proto files using betterproto.

This plugin is based on repo-config's grpc_tools plugin.

Supported Platforms

The following platforms are officially supported (tested):

• Python: 3.11
• Operating System: Ubuntu Linux 20.04
• Architectures: amd64, arm64

Quick Start

To add automatic betterproto code generation to your project, you need to add this package to your build-dependencies in the pyproject.toml file, for example:

[build-system]
requires = [
  "setuptools == 68.1.0",
  "setuptools-betterproto == 0.1.0",
]
build-backend = "setuptools.build_meta"

This uses a default configuration as follows:

• proto_path: This is the root directory where the proto files are located. By default, it is set to ..
• proto_glob: This is the glob pattern to match the proto files. The search is done recursively. By default, it is set to *.proto.
• include_paths: This is a list of paths to be added to the protobuf compiler's include path. By default, it is set to [], but the proto_path directory is always automatically added.
• out_path: This is the directory where the generated Python files will be placed. By default, it is set to ..

These defaults can be changed via the pypackage.toml file too. For example:

[tool.setuptools_betterproto]
proto_path = "proto"
include_paths = ["api-common-protos"]
out_path = "src"

You should add betterproto as a dependency too, for example:

dependencies = ["betterproto == 2.0.0b6"]

Once this is done, the conversion of the proto files to Python files should be automatic. Just try building the package with:

python -m pip install build
python -m build

A new command to generate the files will be also added to setuptools, you can run it manually with:

python -c 'import setuptools; setuptools.setup()' compile_betterproto

You can also pass the configuration options via command line for quick testing, try passing --help at the end of the command to see the available options.
