Retrieve tokens on the path to a matching
It's often interesting to know not only the leaf token as selected by a pattern, but also some of the intermediate steps. Python's re package even provides functionality-- named groups-- to identify particular parts of a matching that may be interesting separately.
An example of how this might look like for grammaregex would be:
example sentence: "Mrs. Robinson graduated from the Wharton School of the University of Pennsylvania in 1980."
pattern: ?P
An example implementation of such behavior (with backwards compatibility: if no ?P<> appears in the pattern to match, just return tokens as before) can be found at this branch.
