Can't use Kernel methods in a Configuration block

[mfischer-zd]

Unadorned methods like catch and throw can't currently be used in a Configuration block without causing load errors.

 credentials do
    provider :aws

    catch(:done) do
      [ENV['AWS_CREDENTIALS_PATH'], File.expand_path("~/.aws/config"), File.expand_path('~/.aws/credentials')].each do |file|
        if File.exist?(file.to_s)
          aws_profile_name ENV['AWS_PROFILE'] || 'tokyo'
          aws_credentials_file file
          throw(:done)
        end
      end
   end

One fully-qualify the methods (e.g. ::Kernel.catch) to avoid errors, but this is a pretty baroque workaround, especially for non-skilled Ruby programmers who are used to DSLs like Chef recipes working without them.

Hi! This is expected behavior of the DSL and I won't be changing this default behavior. One thing that I have on my todo list is adding an option when initializing an attribute struct object to optionally load root namespace constants (chrisroberts/attribute_struct#5). Batali is doing this within a customized struct it uses for parsing a Batali file and I'm looking to extract it to attribute_struct so it can be easily opted into else where. Once that's done, I'll add opt-in ability to the configuration struct.

Cheers!

Have you considered usability when determining what the "expected behavior" should be? I think I have a strong argument.
