#value ⇒ Object

When requesting a step tranformer object value, process it, if it hasn’t alredy been processed, replacing any constants that may be lurking within the value.

Processing it means looking for any escaped characters that happen to be CONSTANTS that could be matched and then replaced. This is done recursively as CONSTANTS can be defined with more CONSTANTS.

Instance Method Details

#constants_from_value(data = @value) ⇒ Object

Look through the specified data for the escape pattern and return an array of those constants found. This defaults to the @value within step transformer as it is used internally, however, it can be called externally if it’s needed somewhere.

def constants_from_value(data=@value)
  data.scan(escape_pattern).flatten.collect { |value| value.strip }
end

#escape_pattern ⇒ Object

Note:

this does not handle the result of method calls

Note:

this does not handle multiple constants within the same escaped area

This defines an escape pattern within a string or regex:

/^the first #{CONSTANT} step$/

This is used below in the value to process it if there happen to be constants defined here.
