magnum

Go enum generator

Installation

go get github.com/phelmkamp/magnum

Usage

1. Define a simple struct type

   1. Enumerate values in the struct tag of the name field

      Format is enum:"value[,value2]":

      type Color struct {
          name string `enum:"red,orange,yellow,green,blue,indigo,violet"`
      }

   2. (Optional) Enumerate values of other fields with additional struct tags (see house.House)

2. Run command

   magnum --path=$SRCDIR

   Better yet, add the following comment to a file at the root of your source tree (e.g. main.go) and run go generate as part of your build process

   //go:generate magnum

3. That's it!

   An *_enum.go file is generated for each *.go file that has enum tags. This file contains accessors for the enumerated values plus methods to marshal/unmarshal a value to/from text (and JSON).
