CSV file reading in ruby 1.9 (fastercsv)

Fastercsv, which is the default in ruby 1.9, uses a hash for specifying the column separator.
Here, we read a tab delimited file and push each row into an array. We also print the first 2 columns.

    require ‘csv’

    ctr = 0

    @data = []

    CSV.foreach(@file,:col_sep => “\t”) do |row|

        @data << row

        puts ” #{row[0]} | #{row[1]} ” #unless row[1] =~ /^\[x\]/

        ctr += 1

    end

    puts ” #{ctr} rows “

To see the other options, do ri CSV::new in a Terminal. Some options are row_sep, field_size_limit, converters, headers (:first_row means the first row is treated as a header, if set to array then the array is used as a header), skip_blanks (true), force_quotes (true), write_headers (true), and a few others.

Dude, that’s nothing. I used to work across the hall from Linus Torvalds, and he used to pull down his pants and shake his balls at passers-by through his office window.
