I think that the PHP port was started but has not been maintained. I could be wrong on that, and maybe the original author would like to chip in on it?

For example: https://github.com/antlr/antlr/blob/master/runtime/Python/tests/t022scopes.g /* recursive rule scopes, access with negative index */ f returns [res] scope { a } @after { $res = $f::a; } : NUM { $f[-2]::a = int($NUM.text); } | '{' f '}' ; It seems that python and java have different implementations for a “negative index”: JAVA scopeSetAttributeRef(scope,attr,expr,index,negIndex) ::= << <if(negIndex)> ((<scope>_scope)<scope>_stack.elementAt(<scope>_stack.size()-<negIndex>-1)).<attr.name> =<expr>; <else> PYTHON scopeSetAttributeRef(scope,attr,expr,index,negIndex) ::= << <if(negIndex)> <!FIXME: this seems not to be used by ActionTranslator...!> self.<scope>_stack[-<negIndex>].<attr.name> = <expr> <else> Questions: - Is there a test suite (i.e. for java) I should be looking at? - Any documentation/more examples on recursive rules scope and what this test does? What is special about negIndex? Thanks J
