Enable environment variable or hide default value

[BobVanB]

I would like to pass default passwords from environment variables and i don't want to see them in the generated help!

What is happening:

    class_option :rancher_secret_key,
                 :type     => :string,
                 :required => false,
                 :hide     => false,
                 :default  => ENV['RANCHER_SECRET_KEY'],
                 :banner   => "<rancher_secret_key>",
                 :desc     => "Default: ${RANCHER_ACCESS_KEY}"

output =>

Options:
  [--rancher-secret-key=<rancher_secret_key>]  # Default: ${RANCHER_ACCESS_KEY}
                                               # Default: asgraweihrasjkfhn378924019hfsadjfha78wrh

What i would like to have:

    class_option :rancher_secret_key,
                 :type     => :string,
                 :required => true,
                 :hide     => false,
                 :env      => "RANCHER_ACCESS_KEY"
                 :banner   => "<rancher_secret_key>",
                 :desc     => "Default: ${RANCHER_ACCESS_KEY}"

output =>

Options:
  --rancher-secret-key=<rancher_secret_key>    # Default: ${RANCHER_ACCESS_KEY}

This will results in the following behaviour:

1. the contents of ENV["RANCHER_ACCESS_KEY"] is hidden
2. if param is not given, the ENV is used
3. if both are nog given, the boolean for required is activated resulting in an error

Other solution that could solve my problem
Hide the default value!

    class_option :rancher_secret_key,
                 :type     => :string,
                 :required => true,
                 :hide     => false,
                 :hide_default => true,
                 :default => ENV["RANCHER_ACCESS_KEY"],
                 :banner   => "<rancher_secret_key>",
                 :desc     => "Default: ${RANCHER_ACCESS_KEY}"

output =>

Options:
  --rancher-secret-key=<rancher_secret_key>    # Default: ${RANCHER_ACCESS_KEY}

@rafaelfranca

Hi, can you review this issue and make a choice?
That way i can develop towards that choice.

With kind regards,

Bob

I think it makes sense. Sorry for the delay on replying to this, but if you are still interested in implementing it would be great.

Goodmorning @rafaelfranca , i'm not interested thank you. We choose a different library that was matching our needs. This was something i stumbled on during review.
