Not downing Komodo ide but if your looking for a free one netbeans has a ide and a pluggin that supports ruby. I have just started using so im still figuring it out but it seems to be pretty nice.
Also thanks for posting your tutorial’s.

hi i keep on getting syntax error, unexpected ‘,’
if book[title.to_sym] = nil? 

Any thoughts on why? :)

Jake Day Williams says:

The next Ruby programming tutorial will be uploaded tomorrow. We will be discussing Create Read Update and Delete more. Make sure to go over this lesson before we do.

Hi Jacob,
Are you going to continue with the ruby series.  I really like it.  You have done a really good job.

Arpit Jain says:


What if I wanted to update / change the books name.

How would I do that?

Bakhtiyor Ibrogimov says:

good job. Thank you!!!

Adam Recvlohe says:

I thought I would share an easier method for putting in the titles.    
title = gets.chomp.gsub(/s+/, “_”).to_sym

This way you can input text as a string in the terminal (i.e. Anne Frank), and it will come out as a symbol (i.e. :Anne_Frank). I hope this helps.
