# frozen-string-literal: true
#
# The string_date_time extension provides String instance methods
# for converting the strings to a date (e.g. String#to_date), allowing
# for backwards compatibility with legacy Sequel code.
#
# These methods calls +parse+ on the related class, and as such, can
# result in denial of service in older versions of Ruby for large
# untrusted input, and raise exceptions in newer versions of Ruby.
#
# To load the extension:
#
# Sequel.extension :string_date_time
class String
# Converts a string into a Date object.
def to_date
Date.parse(self, Sequel.convert_two_digit_years)
rescue => e
raise Sequel.convert_exception_class(e, Sequel::InvalidValue)
end
# Converts a string into a DateTime object.
def to_datetime
DateTime.parse(self, Sequel.convert_two_digit_years)
rescue => e
raise Sequel.convert_exception_class(e, Sequel::InvalidValue)
end
# Converts a string into a Time or DateTime object, depending on the
# value of Sequel.datetime_class
def to_sequel_time
if Sequel.datetime_class == DateTime
DateTime.parse(self, Sequel.convert_two_digit_years)
else
Sequel.datetime_class.parse(self)
end
rescue => e
raise Sequel.convert_exception_class(e, Sequel::InvalidValue)
end
# Converts a string into a Time object.
def to_time
Time.parse(self)
rescue => e
raise Sequel.convert_exception_class(e, Sequel::InvalidValue)
end
end
