Completely convinced of the benefits of Perl for the implementation of language processors and after doing a deep review of the state of the art on parser generation in Perl, we have identified a clear need for a powerful tool that accepts attribute grammars and builds compilers in Perl. The ob jective of this paper is to present a solution based on the developing of a back-end for ANTLR to generate attribute based language processors in Perl, to overcome the lack of this kind tools described in the preliminary study referred above. To achieve the intended ob jective, the parser generator tool ANTLR was studied in detail to understand its components and to plan the best strategies to perform the necessary retargeting of its back-end. In this process, the Java compilers generated by ANTLR were analysed carefully to learn the algorithms ad...
