Optionwrite_converters¶↑

Specifies converters to be used in generating fields. SeeWrite 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"

See alsoWrite Converters

Raises an exception if the converter returns a value that is neithernil nor String-convertible:

bad_converter =proc {|field|BasicObject.new }# Raises NoMethodError (undefined method `is_a?' for #<BasicObject:>)CSV.generate_line(['a','b','c'],write_converters:bad_converter)
