====== Option +quote_char+
|
|
|
|
Specifies the character (\String of length 1) used used to quote fields
|
|
in both parsing and generating.
|
|
This String will be transcoded into the data's \Encoding before use.
|
|
|
|
Default value:
|
|
CSV::DEFAULT_OPTIONS.fetch(:quote_char) # => "\"" (double quote)
|
|
|
|
This is useful for an application that incorrectly uses <tt>'</tt> (single-quote)
|
|
to quote fields, instead of the correct <tt>"</tt> (double-quote).
|
|
|
|
Using the default (double quote):
|
|
str = CSV.generate do |csv|
|
|
csv << ['foo', 0]
|
|
csv << ["'bar'", 1]
|
|
csv << ['"baz"', 2]
|
|
end
|
|
str # => "foo,0\n'bar',1\n\"\"\"baz\"\"\",2\n"
|
|
ary = CSV.parse(str)
|
|
ary # => [["foo", "0"], ["'bar'", "1"], ["\"baz\"", "2"]]
|
|
|
|
Using <tt>'</tt> (single-quote):
|
|
quote_char = "'"
|
|
str = CSV.generate(quote_char: quote_char) do |csv|
|
|
csv << ['foo', 0]
|
|
csv << ["'bar'", 1]
|
|
csv << ['"baz"', 2]
|
|
end
|
|
str # => "foo,0\n'''bar''',1\n\"baz\",2\n"
|
|
ary = CSV.parse(str, quote_char: quote_char)
|
|
ary # => [["foo", "0"], ["'bar'", "1"], ["\"baz\"", "2"]]
|
|

Raises an exception if the \String length is greater than 1:
|
|
# Raises ArgumentError (:quote_char has to be nil or a single character String)
|
|
CSV.new('', quote_char: 'xx')
|
|
|
|
Raises an exception if the value is not a \String:
|
|
# Raises ArgumentError (:quote_char has to be nil or a single character String)
|
|
CSV.new('', quote_char: :foo)
