Milarepa
A {Perl} {BNF} {parser generator} by Jeffrey Kegler
. Milarepa takes a source {grammar}
written in a mixture of {BNF} and {Perl} and generates Perl
source, which, when enclosed in a simple wrapper, parses the
language described by the grammar. Milarepa is not restricted
to {LRn grammars}, and the parse logic follows directly from
the BNF. It handles {ambiguous grammar}s, ambiguous tokens
(tokens which were not positively identified by the lexer) and
allows the programmer to change the start symbol. The grammar
may not be {left recursive}. The input must be divided into
sentences of a finite maximum length. There is no fixed
distinction between {terminal}s and non-terminals, that is, a
symbol can both match the input AND be on the left hand side
of a production. Multiple Marpa grammars are allowed in a
single Perl program.
