As a ruby beginner, I would be grateful for any links to a ruby reference that is arranged in ASCII sequence. I've seen many good tutorials that will teach me ruby from beginning to end. But I'm a weekend (or month-end) programmer who wants to learn a language just to do bits and pieces for myself. I don't want to read 600 pages to find out what "?" is used for. I look online for a piece of code that will already do 75% of what I'm looking for - and then modify it. (I think this is called "not re-inventing the wheel", AKA "re-usable code). For example, I wanted a piece of code that would read and write CSV files. I found a good link. Within this link, there is the following line: last_name.length==0 ? printf(",") : printf("\"%s\",", last_name) For this line, I would like to find a reference that explains the following items in ASCII sequence: ? == %s : \ printf Probably all of these items would be explained in a good tutorial, but it might take hours to find them. -- Posted via http://www.ruby-forum.com/.
