Convert string to Boolean using Regular Expressions
Regular expressions can be employed to match specific patterns in strings, such as “true” or “false”, and then convert them to Boolean values.
Syntax:
!!(string =~ /^(true|t|yes|y)$/i)
Example: In this example we uses a regular expression /^(true|t|yes|y)$/i to match strings like “true”, “t”, “yes”, or “y” regardless of case. The expression !!(string =~ /^(true|t|yes|y)$/i) returns true if the string matches the pattern, otherwise false.
def convert_to_boolean_using_regex(string)
!!(string =~ /^(true|t|yes|y)$/i)
end
# Test examples
string1 = "True"
string2 = "false"
string3 = "Yes"
puts "String: #{string1}, Boolean Value: #{convert_to_boolean_using_regex(string1)}" # Output: true
puts "String: #{string2}, Boolean Value: #{convert_to_boolean_using_regex(string2)}" # Output: false
puts "String: #{string3}, Boolean Value: #{convert_to_boolean_using_regex(string3)}" # Output: true
Output
String: True, Boolean Value: true String: false, Boolean Value: false String: Yes, Boolean Value: true
