====== Option +header_converters+
Specifies a \String converter name or an \Array of converter names.
Default value:
CSV::DEFAULT_OPTIONS.fetch(:header_converters) # => nil
Identical in functionality to option {converters}[#class-CSV-label-Option+converters]
except that:
- The converters apply only to the header row.
- The built-in header converters are +:downcase+ and +:symbol+.
Examples:
str = <<-EOT
foo,0
bar,1
baz,2
EOT
headers = ['Name', 'Value']
# With no header converter
csv = CSV.parse(str, headers: headers)
csv.headers # => ["Name", "Value"]
# With header converter :downcase
csv = CSV.parse(str, headers: headers, header_converters: :downcase)
csv.headers # => ["name", "value"]
# With header converter :symbol
csv = CSV.parse(str, headers: headers, header_converters: :symbol)
csv.headers # => [:name, :value]
# With both
csv = CSV.parse(str, headers: headers, header_converters: [:downcase, :symbol])
csv.headers # => [:name, :value]
