How to run IRB.start in context of current class

Question

I\'ve been just going through PragProg Continuous Testing With Ruby, where they talk about invoking IRB in context of current class to inspect the code

Answer 1

Instead of global you could use instance variables, e.g.:

require 'irb'
@a = "hello"
ARGV.clear
IRB.start

>> @a
=> "hello"
