Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(sym) ⇒ Object

this is truly a magnificent core extension it let’s you do stuff like “foo”.foo? # => true TODO: fuzzy matching for underscores/spaces

Raises:

  • (NoMethodError)

def method_missing sym
  raise NoMethodError.new("Undefined method #{sym} for String") unless sym.to_s.end_with? "?"
  this = self.downcase.gsub("_"," ")
  that = sym.to_s.clip # remove ?
  that = that.downcase.gsub("_"," ")
  this == that
end
