Introduction

YaYacc - an abbreviation for Yet Another Yacc.

The program was created as a syntactical analyzer, which is compatible with original on algorithm analysis and perceived language with yacc. It generate C++ code. Resulting code can be used in multithreaded applications.

Features

Yayacc guarantees:

• Transmission of yacc descriptions into template code on C++ language;
• The work of the resulting code on the same algorithm LALR(1) as yacc;
• Object-oriented method of integration with a lexical analyzer;
• The method of integration with resulting application is incapsulated into object Parser, which gives the result of analysis;
• The possibility of using some syntactical analyzers for several different input languages in one program;
• The possibility of a parallel implementation of some syntactical analyzers the same input language without mutual interlock;
• The possibility of request destruction for objects in stack of analyzer is foresees during restoration from mistakes;

The program guarantees the possibility of embedding of generated programs in systems, with are functioning 24 $\times$ 7. The module returns the correct messages about mistakes when configuration or requirements are incorrect; and remain capable to execution other requirements. This fact confirms the reliability of program.

The supported platforms

1. The operational system: UNIX (Sun Solaris, Linux, FreeBSD) or Windows NT
2. The compiler for yayacc: ANSI C
3. The compiler for a resulting code: ANSI C++
