instance method

Object#CSV

CSV(*args, **options, &block)

# File tmp/rubies/ruby-3.1.3/lib/csv.rb, line 2869
def CSV(*args, **options, &block)
  CSV.instance(*args, **options, &block)
end

Passes args to CSV::instance.

Example

CSV("CSV,data").read
  #=> [["CSV", "data"]]

If a block is given, the instance is passed the block and the return value becomes the return value of the block.

Example

CSV("CSV,data") { |c|
  c.read.any? { |a| a.include?("data") }
} #=> true

CSV("CSV,data") { |c|
  c.read.any? { |a| a.include?("zombies") }
} #=> false

CSV options may also be given.

Example

io = StringIO.new
CSV(io, col_sep: ";") { |csv| csv << ["a", "b", "c"] }
