====== Option +col_sep+
Specifies the \String column 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)
