Ruby 1.9 has adopted FasterCSV as its built-in CSV library. However, it’s in the standard library rather than Ruby 1.9’s core, so you need to manually require it in your application.
After adding a
require 'csv'
to your code, you can then do things such as
CSV.parse("this,is,my,data")
See Ruby 1.9’s standard library CSV documentation for information on using the library.
