Private Instance Methods

d(expression) click to toggle source

Takes an expression (variable, etc.) and evaluates it in the binding of the caller. Then it does a debug printing the variable name, and value

# File lib/debug_print.rb, line 36
def d(expression)
  result = binding.of_caller(1).eval(expression.to_s)
  inspection = result.inspect
  if result.inspect.length < 50
    sout = "\t<#{result.class.name}> #{expression} = #{inspection}" 
  else
    sout  = "\n<#{result.class.name}> #{expression} =\n"
    sout += inspection + "\n\n" 
  end
  DebugPrint.out(sout)
end
