gen (v4)

The stringer typewriter

The stringer typewriter is a fork of Rob Pike’s tool of the same name, which generates readable strings for consts. It is built into gen by default.

To use, mark up a type for which you have consts, using Rob’s example:

// +gen stringer
type Pill int

const (
	Placebo Pill = iota
	Aspirin
	Ibuprofen
	Paracetamol
	Acetaminophen = Paracetamol
)

Then simply gen your package, as normal. You should see a new file, pill_stringer.go, containing the String method for your type.
