Feature #10316: Failsafe CSV.foreach

I've been looking for a CSV.foreach equivalent which either

• ignores malformed CSV rows
• or returns a nil row or a row with a parsed success flag.

Can I collaborate to develop this functionallity? Symply sending a patch here?

You can implement it with the following code:

CSV.open(path) do |csv|
  loop do
    begin
      row = csv.shift
    rescue ArgumentError # For old csv library
      # ignore
    rescue CSV::MalformedCSVError # For the latest csv library (not released yet)
      # ignore
    else
      # Do what you want with "row"
    end
  end
end
