This group discusses Rails, not raw Ruby. You'd get better answers on the ruby newsgroup/mailing list/thing.

And I would just use YAML::load to read the file, and let YAML do all that low-level parsing and representing.

This is how you can do it:

ar = ha = {} IO.foreach("book_list.txt") do |line| catalog=line.chomp.split(",") products.store(items[0].to_i, [catalog[1],catalog[2].to_i,catalog[3].to_i) # To array ar << catalog # To Hash ha['some_key'] = catalog end

It can be done as oneliner: ar= File.readlines("book_list.txt").each {|line| ar << line.chomp.split(",")}
