ddex-gen

ddex-gen

DDEX code generator for protobuf-generated files.

What It Does

Generates DDEX-specific Go code extensions for .pb.go files:

1. enum_strings.go - String conversion methods for enums (XMLString(), parsers)
2. *.xml.go - XML marshaling methods with namespace support (MarshalXML, UnmarshalXML)
3. registry.go - Dynamic message type registry for auto-detection

Installation

go install github.com/OpenAudio/ddex-proto/cmd/ddex-gen@latest

Usage

After generating .pb.go files with buf generate:

# Default: processes ./gen directory
ddex-gen

# Specify custom directory
ddex-gen ./my-gen-dir

# Verbose mode
ddex-gen -verbose ./gen

Example Workflow

# 1. Generate protobuf Go code
buf generate

# 2. Generate DDEX extensions
ddex-gen

# Now your code has:
# - gen/ddex/ern/v432/enum_strings.go
# - gen/ddex/ern/v432/v432.xml.go
# - gen/registry.go

As a Library

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

err := ddexgen.Generate("./gen", true) // dir, verbose
if err != nil {
    log.Fatal(err)
}
