hi , I am on my way of migrating an antlr 2.7.1 parser to the 2.7.2 new version available , my parser is divided into two pass : 1) Lexical + Syntaxic => emitting AST tree 2) AST tree parsing => emiting Internal intermediate representation. My problem occurs on AST tree parsing on following kind of rules : on above rules I got the following antlr parser error which was I do not have when using antlr 2.7.1 : #(LIBNAME! t2=techprintExpression) techprint.tree.g:1579:17: Suffixing a root node with '!' is not implemented Is it a regression or current version limitation ? if yes will it be fi

hi ,
I am on my way of migrating an antlr 2.7.1 parser to
the 2.7.2 new version available , my parser is divided into two pass :
1) Lexical + Syntaxic => emitting AST tree
2) AST tree parsing => emiting Internal intermediate representation.
My problem occurs on AST tree parsing on following kind of rules :
on above rules I got the following antlr parser error which was I do not have when using antlr 2.7.1 :
#(LIBNAME! t2=techprintExpression)
techprint.tree.g:1579:17: Suffixing a root node with '!' is not implemented
Is it a regression or current version limitation ? if yes will it be fixed , otherwise any workaround is welcome.
Thanks in advance for any input on above topic
