Introduction

PRECC eXtended is an infinite-lookahead compiler-compiler for context dependent grammars developed during and after the ESPRIT II REDO project. The generated code is ANSI C. Specification scripts are in very extended BNF with inherited and synthetic attributes allowed. Scripts can be compiled in separate modules, and linked together later. Meta-production rules are allowed. The technology is essentially LL(

) with optimizations. A converter for yacc scripts is available.

News concerning PRECC is issued from time to time on the moderated (and therefore recommended) comp.compilers newsgroup including in the language tools catalog.

Obtaining PRECCX

Versions of PRECCX are available for use under UNIX (e.g., on a Sun workstation) in gzip (compressed) tar format and also for use on a PC under MS-DOS as several zip format files.

UNIX version available as a single "gzipped" tar format file.

MS-DOS version in a directory including an index and information.

PRECC examples available as a single "gzipped" tar format file.

PRECC 2.44 for Linux, a single "gzipped" tar format file.

See also information and index of compiler tools including PRECC.
Current stable widely available version.

Latest PRECC version 2.45 FTP directory.

More experimental version.

A Z notation grammar is available in info-zip format and gzipped Unix tar format for use with PRECC. The former is suitable for use under DOS, apart from the Unix makefile. See PRECC support for parsing the Z notation.

See new Web interface to PRECC 2.* (PRECCX) CVS Tree.

Please note that PRECCX under continual development and is available on an as is basis, although comments are of course welcome.

Documentation

The following on-line documentation is available:

PRECCX User Manual in HTML format (large).
Unix-style manual page (also in smaller compressed PostScript format).
PRECC FAQ (Frequently Asked Questions) - currently in plain text only.
