ddexgen

pkg/ddexgen

DDEX code generation library for protobuf-generated Go files.

Purpose

This package provides programmatic access to DDEX-specific code generation. It's used by the ddex-gen and protoc-gen-ddex CLI tools, but can also be imported directly.

What It Generates

1. enum_strings.go - String conversion methods for enums
2. *.xml.go - XML marshaling/unmarshaling with namespace support
3. registry.go - Dynamic message type registry

Usage

import "github.com/OpenAudio/ddex-proto/pkg/ddexgen"

func main() {
    // Generate DDEX extensions for all .pb.go files in ./gen
    err := ddexgen.Generate("./gen", true) // directory, verbose
    if err != nil {
        log.Fatal(err)
    }
}

Features

• Automatic detection - Scans for .pb.go files and processes them
• Enum string methods - Generates XMLString() and Parse*String() functions
• XML marshaling - Adds proper namespace handling for DDEX compliance
• Registry - Dynamic message type detection from XML
