README¶

go-enum-encoding

go install github.com/nikolaydubina/go-enum-encoding@latest

• 200 LOC
• simple, fast, strict
• generate encoding/decoding, tests, benchmarks

type Color struct{ c uint8 }

//go:generate go-enum-encoding -type=Color
var (
    UndefinedColor = Color{} 	// json:""
    Red            = Color{1}	// json:"red"
    Green          = Color{2}	// json:"green"
    Blue           = Color{3}	// json:"blue"
)

iota is ok too

type Size uint8

//go:generate go-enum-encoding -type=Size
const (
    UndefinedSize Size = iota // json:""
    Small                     // json:"small"
    Large                     // json:"large"
    XLarge                    // json:"xlarge"
)

• http://github.com/zarldev/goenums - does much more advanced struct generation, generates all enum utilities besides encoding, does not generate tests, uses similar notation to trigger go:generate but with different comment directives (non-json field tags)
