what is exPath?

metormaon commented 3 years ago

ExPath is a data structure that can point to a “location” within a grammatical expression.

For example, in the expression

B | (C & [D])

the ExPath to D would represent the path from the root, through child #2 of an Or expression, through child #2 if a Then expression, then through an Optional expression, to D itself.

When I search for a pattern in expressions, I generate ExPaths for all the found patterns, and then I can transform the patterns into something else, for example.

ExPath is a just a tool I’m using to demonstrate rule optimization, for example.
