API Client Generator for Python

A generator for protocol buffer described APIs for and in Python 3.

This is a generator for API client libraries for APIs specified by protocol buffers, such as those inside Google. It takes a protocol buffer (with particular annotations) and uses it to generate a client library.

Purpose

This library replaces the monolithic generator with some improvements:

• An explicit normalized format for specifying APIs.
• Light weight, in-language code generators.

Bazel

This generator can be called from Bazel, which is a recommended way of using it inside a continuous integration build or any other automated pipeline.

Clone the googleapis repository $ git clone https://github.com/googleapis/googleapis.git

Create the targets

You need to add the following targets to your BUILD.bazel file.

load(
    "@gapic_generator_python//rules_python_gapic:py_gapic.bzl",
    "py_gapic_library"
)

load(
    "@gapic_generator_python//rules_python_gapic:py_gapic_pkg.bzl",
    "py_gapic_assembly_pkg"
)

py_gapic_library(
    name = "documentai_py_gapic",
    srcs = [":documentai_proto"],
)

py_gapic_assembly_pkg(
    name = "documentai-v1beta2-py",
    deps = [
        ":documentai_py_gapic",
    ],
)

Compiling an API

Using Bazel:

bazel build //google/cloud/documentai/v1beta2:documentai-v1beta2-py

Using Protoc:

# This is assumed to be in the `googleapis` project root.
$ protoc google/cloud/vision/v1/*.proto \
    --python_gapic_out=/dest/
