Could you open a PR for it?
from csv.
Could you add out_write_headers: true
option?
from csv.
No dice on that one, results in the header row being sent to the block, which results in the following:
irb(main):006> CSV.filter(input, output, headers: true, out_write_headers: true) { |row| row['Date and Time'] = "#{row['Date and Time']}+HUH"}
(irb):6:in `[]': no implicit conversion of String into Integer (TypeError)
CSV.filter(input, output, headers: true, out_write_headers: true) { |row| row['Date and Time'] = "#{row['Date and Time']}+HUH"}
^^^^^^^^^^^^^^^

... 6 levels...
from csv.
The first row
is the header and it's an Array
:
CSV.filter(input, output, headers: true, out_write_headers: true) { |row| row['Date and Time'] = "#{row['Date and Time']}+HUH" unless row.is_a?(Array)}
from csv.

:CSV.filter(input, output, headers: true, out_write_headers: true) { |row| row['Date and Time'] = "#{row['Date and Time']}+HUH" unless row.is_a?(Array)}
Okay I've found a unit test that describes this behaviour
The recipe really should be updated https://ruby.github.io/csv/doc/csv/recipes/filtering_rdoc.html#label-Recipe-3A+Filter+String+to+String+with+Headers
