Subject: [ruby-core:56163] [ruby-trunk - Feature #8683][Rejected] CSV library can't append to the current row. It should be able to.


Issue #8683 has been updated by nobu (Nobuyoshi Nakada).

Status changed from Open to Rejected

CSV class is a reader/writer, not to edit CSV data on memory.
You may want to use CSV::Table instead.

The CSV library can only add *new* rows, and it provides no way to update the current row after it has been created.

For example:
CSV.generate headers: true do |csv| 
  csv << ["one"]
  
  ["two", "three"].each do |e| 
    csv << e # This creates a new row, I want to append.
  end
  csv.headers << ["two", "three"] # No, this doesn't work either.
end

Is this possible? I find it hard to believe the API could be _that_ limited and inflexible.
