Milarepa
<tool> A Perl BNF parser generator by Jeffrey Kegler
<jeffrey@netcom.com>. 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 grammars, 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
terminals 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.
Version: Prototype 1.0.
