SimpleEnum - Use Enumerations in Elixir

News Announcing

Hi everyone,

I have just published the first version of a library that I have been using in my projects for over a year now: SimpleEnum - a simple library that implements Enumerations in Elixir.

SimpleEnum was designed to be :

  • fast: being based on a macro system, access to the Enum will be resolved at compile time when it is possible
  • simple: the use of the library has been designed to be as simple as possible for a developer to use. In addition to providing Enums, it automatically defines their types and provides an introspection system.

Examples of uses can be found in the documentation : SimpleEnum — simple_enum v1.0.0

Proposals :

To improve SimpleEnum, I had several ideas like

  • Add the defenump function in order to create private Enums: currently, all Enums are public
  • Add an EnumValueError exception for developers who need rescue. Currently, ArgumentError is used
  • Add a decorator @allow_duplicate_values true or @unique false to allow duplicates values in Enum
  • Add macros is_enum/1, is_enum_key/1 and is_enum_value/1 (eg. is_color(:red), is_color_key(:red) and is_color_value(:red)) for each Enum. An example of implementation can be found here.

What do you think? Would you need a feature in the list or another one?

Any issues, suggestions or contributions are welcome.
Cheers
