Overview

Wrap Squash::Ruby’s slightly nasty configuration method with a config-block class

Squash accepts configuration via a key-value hash passed to the #configure class method and provides reading that configuration by passing a key the #configuration class method and returning the value for that key/attribute. This class attempts to emulate a tradtional Configure-block class (a la Struct / OpenStruct) but calls-into Squash’s configuration methods; this helps make the rest of the SquashRepeater Configure class simpler. This class is probably more-like OpenStruct in-use, as it doesn’t do any checking of “allowed” attributes, which is more-similar to how Squash treats configuration attr’s. I didn’t bother implementing all the methods you might expect, as this should really only be consumed by SquashRepeater users, at a fairly simplistic level.

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_sym, val = nil) ⇒ Object

def method_missing(method_sym, val=nil)
  fail "Can't extract a meaningful name from the provided method_sym" unless method_sym.to_s =~ /^(.+?)=?$/
  key = $1.to_sym

  if method_sym.to_s =~ /=$/
    # Setter
    Squash::Ruby.configure({ key => val })
  end
  # Getter
  #NB: Always return the value for the key
  Squash::Ruby.configuration(key)
end
