Greetings:
Whilst adding even more complexity to the grammar upon which I am working, I
got this message from the tool:
What does this mean?
The message came out after adding this fragment to my grammar. I had to
enable backtracking to get ANTLR to handle the tail
differences without complaining.
perl_lpar_ere_expression
options{
backtrack=true;
}
:
perl_lpar_ere RPAREN
| perl_lpar_ere ALTERNATE_PAREN
;
perl_lpar_ere : perl_lpar ere ;
Tool Message:
