NamespacedEnums

Important: Use SuperEnum Instead

I wrote this package assuming that nothing already existed that solved the problem. It turns out that SuperEnum does the same and more! Use that package instead.

If your module has a lot of enums, you might run into a few problems:

• Your module's namespace becomes polluted with loads of names
• You can't use the same name for two different enums
• You can't tell which enum a value belongs to
• Tab completion is not helpful for finding instances of a certain enum

NamespacedEnums' @nsenum works similarly a regular Enum, but its values are hidden behind a module. To access the values, use EnumName.value1. To access the enum itself, use EnumName.T.

julia> using NamespacedEnums

julia> @nsenum Fruit apple=1 orange=2 kiwi=3;

julia> f(x::Fruit.T) = "I'm a Fruit with value: \$(Int(x))";

julia> f(apple)
ERROR: UndefVarError: apple not defined

julia> f(Fruit.apple)
"I'm a Fruit with value: 1"

namespacedenums.jl's Issues

What is the differences between NamespacedEnums.jl and SuperEnum.jl?

Is it intentionally made different from https://github.com/kindlychung/SuperEnum.jl?

`instances` & instantiate by indices no longer works

@nsenum Fruit apple=1 orange=2 kiwi=3;

julia> Fruit(1)
