Instance Method Details

#transform_value(input) ⇒ String (private)

Transform an input String to a JSON if it contains a colon. It returns the String if not. Also, the first colon is used as a delimiter between the key and the value. Any subsequent colon will be part of the value. Finally, it handles double/single quotes to escape any colon that are not suppose to be a delimiter between the key and the value.

Parameters:

  • input (#to_s)

Returns:

  • (String) —

    representing a JSON if input contains a colon. Otherwise it is a the same as input

def transform_value(input)
  # Regex to find the first colon that is NOT inside quotes
  match = input.match(/((?:[^'":]++|"(?:\\.|[^"])*"|'(?:\\.|[^'])*')*?):(.*)/)

  # If no valid colon is found, return the original string
  return input unless match

  key = match[1].strip  # Extract key (before first valid colon)
  value = match[2].strip # Extract value (after first valid colon)

  # Remove starting and ending quotes and ensure they are valid JSON strings
  key = key.gsub(/^["'](.*)["']$/, '\1').to_json
  value = value.gsub(/^["'](.*)["']$/, '\1').to_json
  "{#{key}: #{value}}"
end

#value=(formatted_value) ⇒ String

Sets Base#value by parsing the formatted_value String and attempting to generate a valid JSON if it contains a colon. Otherwise, it keeps the same value as a String.

Parameters:

  • formatted_value (#to_s)

Returns:

  • (String) —

    representing a JSON if formatted_value contains a colon. Otherwise it is a the same as formatted_value
