====== Option +col_sep+
|
|
|
|
Specifies the \String field separator to be used
|
|
for both parsing and generating.
|
|
The \String will be transcoded into the data's \Encoding before use.
|
|
|
|
Default value:
|
|
CSV::DEFAULT_OPTIONS.fetch(:col_sep) # => "," (comma)
|
|
|
|
Using the default (comma):
|
|
str = CSV.generate do |csv|
|
|
csv << [:foo, 0]
|
|
csv << [:bar, 1]
|
|
csv << [:baz, 2]
|
|
end
|
|
str # => "foo,0\nbar,1\nbaz,2\n"
|
|
ary = CSV.parse(str)
|
|
ary # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
|
|
|
|
Using +:+ (colon):
|
|
col_sep = ':'
|
|
str = CSV.generate(col_sep: col_sep) do |csv|
|
|
csv << [:foo, 0]
|
|
csv << [:bar, 1]
|
|
csv << [:baz, 2]
|
|
end
|
|
str # => "foo:0\nbar:1\nbaz:2\n"
|
|
ary = CSV.parse(str, col_sep: col_sep)
|
|
ary # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
|
|
|
|
Using +::+ (two colons):
|
|
col_sep = '::'
|
|
str = CSV.generate(col_sep: col_sep) do |csv|
|
|
csv << [:foo, 0]
|
|
csv << [:bar, 1]
|
|
csv << [:baz, 2]
|
|
end
|
|
str # => "foo::0\nbar::1\nbaz::2\n"
|
|
ary = CSV.parse(str, col_sep: col_sep)
|
|
ary # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
|
|
|
|
Using <tt>''</tt> (empty string):
|
|
col_sep = ''
|
|
str = CSV.generate(col_sep: col_sep) do |csv|
|
|
csv << [:foo, 0]
|
|
csv << [:bar, 1]
|
|
csv << [:baz, 2]
|
|
end
|
|
str # => "foo0\nbar1\nbaz2\n"
|
|
|

|
|
|
Raises an exception if parsing with the empty \String:
|
|
col_sep = ''
|
|
# Raises ArgumentError (:col_sep must be 1 or more characters: "")
|
|
CSV.parse("foo0\nbar1\nbaz2\n", col_sep: col_sep)
|
|
|
|
Raises an exception if the given value is not String-convertible:
|
|
col_sep = BasicObject.new
|
|
# Raises NoMethodError (undefined method `to_s' for #<BasicObject:>)
|
|
CSV.generate(line, col_sep: col_sep)
|
|
# Raises NoMethodError (undefined method `to_s' for #<BasicObject:>)
|
|
CSV.parse(str, col_sep: col_sep)
