# My take on Mike's source_for method.
# (see http://pragmaticstudio.com/blog/2013/2/13/view-source-ruby-methods)
#
# (1) I named it 'src' rather than source_for (ok, I'm a lazy typer).
# (2) The edit function was broken out as a separate function.
# (3) The edit function is for emacs
# (4) If the method is not defined on the object, and the object 
#     is a class, then see if it is an instance method on the class.
#
# The fourth point allows my to say:

In celebration of Whyday: Rubyists always want to show others the beautiful code 
they have created, hence the question: Has Anybody Seen My Code?

Has Anybody Seen My Code
(sung to the tune of Has Anybody Seen My Gal)

Clean and small, works for all,
Ruby is my all in all.
Has anybody seen my code?

Berlin Clock

Original Reference

Create a representation of the Berlin Clock for a given time (hh::mm:ss).

The Berlin Uhr (Clock) is a rather strange way to show the time. On the top of the clock there is a yellow lamp that blinks on/off every two seconds. The time is calculated by adding rectangular lamps.

# When I posted the results of the Roman Numeral Calculator kata
# earlier this week, I said that I felt that the evolution of the code
# through TDD was much more interesting than the final result.  Let me
# explain.
#
# First, some background.  The goal of this Kata is to produce a
# RomanNumeralCalculator object that converts from arabic numbers to
# Roman numerals, and from Roman numerals back to arabic.

  Then { calculate("1").should == "I" }
