gobuildergen

Generates builder pattern code for Go structs. That's it.

Install

go install github.com/ARUMANDESU/gobuildergen@latest

Usage

Add //go:generate above your struct:

//go:generate gobuildergen --type MyStruct
type MyStruct struct {
    Name    string
    Age     int
    Email   string `builder:"default=\"unknown\""`
    secret  string `builder:"-"`
}

Run:

go generate ./...

This creates myfile_builder_gen.go with a fluent builder:

s := NewMyStructBuilder().
    WithDefault().
    Name("John").
    Age(30).
    Build()

Struct tags

• builder:"default=value" — sets a default value (applied via WithDefault())
• builder:"-" — skips the field entirely
