Ensure that listener sees correct name when lexer rule refers to another lexer rule #239

Closed akosthekiss closed 1 month ago

akosthekiss commented 1 month ago

Since token sub-rules (e.g., fragments) are not represented by unique nodes in the tree, even though listeners are called when the generation of a sub-rule starts or ends, the listeners only see the top-level token node and the name of the top-level lexer rule.

This commit changes this by faking the top-level token node to have the name of the sub-rule rule while generating the sub-rule.
