Cybozu Public Protocol Buffers Schema

This repository contains public Protocol Buffer files and related tools from Cybozu.

This repository forms a Buf module to publish protobuf files on BSR. You can import packages in this repository by adding the following lines to buf.yaml.

version: v1
deps:
- buf.build/cybozu/protobuf

If you are not familiar with buf, read https://docs.buf.build/manuals/cli/overview

cybozu.validate

This protobuf package provides custom options to normalize and validate messages. Read examples/validation.proto for example usage.

You can get the code generator for Go as follows:

$ go install github.com/cybozu/protobuf/cmd/protoc-gen-go-cybozu-validate@latest

or download prebuilt binaries from Releases.

The following is an example buf.gen.yaml to generate validation code:

version: v1
plugins:
  - plugin: go
    out: .
    opt: paths=source_relative
  - plugin: go-cybozu-validate
    out: .
    opt: paths=source_relative

Versioning and backward-compatibility

We keep backward-compatibility of Protocol Buffers files. When we want to add breaking changes to Protocol Buffers files, we create a different package like cybozu.foo.v2 not to break the current package.

However, the generated code in this repository may not be backward compatible. For example, Go code generated by protoc-gen-go may not be always backward compatible.

So, we use a semver with major version zero (0.y.z) to tag this repository to declare the generated code may bring breaking changes.

For developers

Running make create-tag creates a new tag and push it to GitHub automatically. The rest of the release process will be done by GitHub Actions.
