Accent is a compiler-compiler that does not impose any restrictions on
grammars. You don't have to adapt your grammar to the limitations of
a particular parsing technique. This makes Accent much simpler to

Accent's specification language is similar to that of Yacc. Like
Yacc, Accent cooperates with Lex.

Accent supports the Extended Backus-Naur Form. It provides inherited
and synthesized attributes (using symbolic names instead of numbers).

Grammar ambiguities are reported and resolved at the logical level of
the specification, not in terms of a parsing technique. You don't
have to restructure your rules. Accent is the first system that
provides a framework to resolve all ambiguities.

Accent parsers require more resources than Yacc parsers, but they are
an alternative for a wide range of applications. Our Java parser
processes thousands of lines in a few seconds.
