Documentation generator plugin for Google Protocol Buffers
protoc-gen-doc is a documentation generator plugin for Google Protocol Buffers that extracts comments from `.proto` files and generates documentation in multiple formats including HTML, JSON, DocBook, and Markdown. The tool supports both proto2 and proto3 syntax and is built in Go, with distribution available via Go modules, Docker images, Maven Central, and pre-built binaries for various platforms. It integrates with the protoc compiler through command-line options and supports custom Go templates for documentation output, as well as features like excluding specific comments and generating camel-case field names.
