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

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

```go
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

```go
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)
