That would be less flexible to the user, if they want to parse such a thing with trailing garbage. Perhaps supplying both TOP and another rule which could be selected by :target. However, lots of grammars are going to need this, and it would be pathetic to have a smattering of differently named rules for this, so there is a good argument for a standardized flag.

How about just adding ^ and $ to the TOP rule?

That is “explicit EOF token”. If there is garbage in the input, the EOF token cannot be matched and the parse fails.
Parsing a partial file can be useful when parsing a file to do syntax highlighting a programming language or extracting information like defined functions on the fly in an editor.

antlr has the same “problem”. There you need to add an explicit token in the rule to be parsed.

Was that just two years ago? It seems like an eternity.

These days both Rakudo and Niecza have big Ints built in. FatRat too.

oops just realized I’m 2 years behind you ! Coulda sworn that “int” after “Feb 3″ was bigger by 2

I wonder how hard would be to add proper Perl6 interface to libmarpa C library (the core of Marpa)…
