====== 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)
|
|
|
|
For examples in this section:
|
|
ary = ['a', 'b', 'c']
|
|
|
|
Using the default:
|
|
str = CSV.generate_line(line)
|
|
str # => "a,b,c\n"
|
|
ary = CSV.parse_line(str)
|
|
ary # => ["a", "b", "c"]
|
|
|
|
Using +:+ (colon):
|
|
col_sep = ':'
|
|
str = CSV.generate_line(ary, col_sep: col_sep)
|
|
str # => "a:b:c\n"
|
|
ary = CSV.parse_line(str, col_sep: col_sep)
|
|
ary # => [["a", "b", "c"]]
|
|
|
|
Using +::+ (two colons):
|
|
col_sep = '::'
|
|
str = CSV.generate_line(ary, col_sep: col_sep)
|
|
str # => "a::b::c\n"
|
|
ary = CSV.parse_line(str, col_sep: col_sep)
|
|
ary # => [["a", "b", "c"]]
|
|

Raises an exception if given the empty \String:
|
|
col_sep = ''
|
|
# Raises ArgumentError (:col_sep must be 1 or more characters: "")
|
|
CSV.parse_line("a:b:c\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(line, col_sep: col_sep)
|
|
# Raises NoMethodError (undefined method `to_s' for #<BasicObject:>)
|
|
CSV.parse(str, col_sep: col_sep)
