Like most modules named # some variant of 'util', its methods are probably not particularly useful # to those who aren't developing the library itself. module Utils module_function # Given a +name+ in a name_with_underscores or a name-with-dashes format, # returns the CamelCase version of +name+. # # If the +name+ is already CamelCased, nothing happens. # # Examples: # # require 'rss/utils' # # RSS::Utils.to_class_name("sample_name") # # => "SampleName" # RSS::Utils.to_class_name("with-dashes") # # => "WithDashes" # RSS::Utils.to_class_name("CamelCase") # # => "CamelCase" def to_class_name(name) name.split(/[_\-]/).collect do |part| "#{part[0, 1].upcase}#{part[1..-1]}" end.join("") end # Returns an array of two elements: the filename where the calling method # is located, and the line number where it is defined. # # Takes an optional argument +i+, which specifies how many callers up the # stack to look. # # Examples: # # require 'rss/utils' # # def foo # p RSS::Utils.get_file_and_line_from_caller # p RSS::Utils.get_file_and_line_from_caller(1) # end # # def bar # foo # end # # def baz # bar # end # # baz # # => ["test.rb", 5] # # => ["test.rb", 9] # # If +i+ is not given, or is the default value of 0, it attempts to figure # out the correct value. This is useful when in combination with # instance_eval. For example: # # require 'rss/utils' # # def foo # p RSS::Utils.get_file_and_line_from_caller(1) # end # # def bar # foo # end # # instance_eval <<-RUBY, *RSS::Utils.get_file_and_line_from_caller # def baz # bar # end # RUBY # # baz # # # => ["test.rb", 8] def get_file_and_line_from_caller(i=0) file, line, = caller[i].split(':') line = line.to_i line += 1 if i.zero?
