Supercharge your environment variables in Elixir. Parse and validate with compile time access guarantees, defaults, fallbacks and app pre-boot validations.

mahaul's Issues

[Feature Request]: Add fun option

In some cases a 1-1 mapping between env var and function name is not ideal, so a [fun: :new_function_name] could be added.

[Feature Request]: Add base64 option

I'm currently dealing with a lot of base64 encrypted env variables, it would be helpful to have a base64: true option which decodes the value before parsing it.

Surprising behavior when passing an invalid type

Hi there! 👋
First off, thanks for making this library! I'm excited to see an alternative approach to using environment variables in Elixir 🎉

I didn't read the docs thoroughly the first time I started using this and I set up my env like so:

defmodule Dash.Env do
  use Mahaul,
    TRELLO_API_KEY: [type: :string],
    TRELLO_API_TOKEN: [type: :string],
    PIRATE_WEATHER_API_KEY: [type: :string]

This results in Dash.Env.validate() giving the following error even when those environment variables are set:

14:54:01.654 [warning] Elixir.Mahaul.Helpers: missing or invalid environment variables.
TRELLO_API_KEY
TRELLO_API_TOKEN
PIRATE_WEATHER_API_KEY

{:error, "TRELLO_API_KEY\nTRELLO_API_TOKEN\nPIRATE_WEATHER_API_KEY"}

After reading the docs I found that the correct type is :str, not :string, while I do have a slight preference for both of them working that's not my main point here. My main point is that I think that either at compile-time or runtime when calling Dash.Env.validate() I should get an error that the type was not recognized.

[Feature Request]: List of type

Would it be possible to add a {:list, a} type which parses a comma separated string into a list of type a?

`default_test` option

Hi, cool library :)

It would be great to have a default_test option, similar to default_dev.
