Path Mapper

from David:

The PathMapper is a very complicated piece of work, thousands of lines of code go into evaluating and parsing the mapping masks. You can however use PathMapper logic from your own code. What you need to do is create a

GH_LexerCombo

which contains the source and target mappings. Then you can call

GH_Lexer.PerformLexicalReplace()

to map a data tree.
