magnum

Go enum generator

Installation

go get github.com/phelmkamp/magnum

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)
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
```
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).
