Subject: [ruby-core:56162] [ruby-trunk - Feature #8683] CSV library can't append to the current row. It should be able to.


Issue #8683 has been updated by robertgleeson (Robert Gleeson).


I guess I could settle for:

headers = ["one"]
CSV.generate headers: true do
  ["two", three"].each do |e| 
    headers << e
    csv << headers
  end
end

but, this is preferable:
headers = ["one"]
CSV.generate headers: true do
  ["two", three"].each do |e| 
    csv.append_to_current_row(e)
  end
end

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.
