[antlr-interest] ANTLR3 Capturing System.out.println

[Kailey Joanette]

That particular set of code does not work. LA doesn't exist.  And doing input.LA doesn’t work either because ... well apparently that returns an int...

Kailey--

You want to use semantic predicates here, not
keywords, for names.  That is, try

println
    :
    {LA(1).getText().equals("System") &&
LA(3).getText().equals("println"} => ID
    DOT ID
    LPAREN
    outputExpression
    RPAREN
    ;

Still better is to use a symbol table for functions to
be translated (still using sempreds for
identification).
