[antlr-interest] Puzzled by leading dot

[Bryan Ewbank]

I think what you need is to add EOF and/or newline processing.  For
EOF processing, change this:
     line : item (SEMI item)*
to this:
     line : item (SEMI item)* EOF

For newline/whitespace processing, you need to mark tokens as being
skipped.  I don't use ANTLR for lexing, but look for "SKIP" in the
manual and/or the examples.  This will allow ANTLR to ignore the
whitespace between your tokens.
