How do I add 'each' method to Ruby object (or should I extend Array)?
I have an object Results that contains an array of result objects along with some cached statistics about the objects in the array. I'd like the Results object to be able to behave like an array. My first cut at this was to add methods like this def <<(val) @result_array << val end This feels very c-like and I know Ruby has better way. I'd also like to be able to do this Results.each do |result| r
Iterate through every file in one directory
How do I write a loop in ruby so that I can execute a block of code on each file? I'm new to ruby, and I've concluded that the way to do this is a do each loop. The ruby file will be executed from a different directory than the directory I want to loop through. I've tried the Dir.foreach and I couldn't get it to work.
