Option write_converters
¶ ↑
Specifies converters to be used in generating fields. See Write Converters
Default value:
CSV::DEFAULT_OPTIONS.fetch(:write_converters) # => nil
With no write converter:
str = CSV.generate_line(["\na\n", "\tb\t", " c "]) str # => "\"\na\n\",\tb\t, c \n"
With a write converter:
strip_converter = proc {|field| field.strip } str = CSV.generate_line(["\na\n", "\tb\t", " c "], write_converters: strip_converter) str # => "a,b,c\n"
With two write converters (called in order):
upcase_converter = proc {|field| field.upcase } downcase_converter = proc {|field| field.downcase } write_converters = [upcase_converter, downcase_converter] str = CSV.generate_line(['a', 'b', 'c'], write_converters: write_converters) str # => "a,b,c\n"
