BTYACC -- backtracking yacc =========================== BTYACC was created by Chris Dodd using ideas from many places and lots of code from the Berkeley Yacc distribution, which is a public domain yacc clone put together by the good folks at Berkeley. This code is distributed with NO WARRANTEE and is public domain. It is certain to contain bugs, which you should report to: email@example.com Vadim Maslov of Siber Systems <firstname.lastname@example.org> considerably modified BTYACC to make it suitable for production environment. Several people have suggested bug fixes that were incorporated into BtYacc. See the README.BYACC files for more about Berkeley Yacc and other sources of info. btyacc is backwards compatible with the POSIX yacc specification in IEEE 1003.2. A copy of the relevant specification may be available at ftp://ftp.fi.netbsd.org/ftp/pub/doc/posix/p1003.2/d11.2/a.3 http://www.siber.com/btyacc/ is the current home of BtYacc. It is provided courtesy of Siber Systems http://www.siber.com/. Building BtYacc --------------- by Chris Dodd and Vadim Maslov We used GCC and GNU make to compile BtYacc both on UNIX and WIN32 paltforms. You are welcome to try different combinations of makes and compilers. Most likely it will work, but it may require Makefile changes. There is no config script. Just type "make" and it should compile. AWK. If you want to change file btyaccpa.ske (backtracking parser skeleton), you will need awk to compile it into skeleton.c file. We used GNU AWK (gawk) version 3.0. It is known that using older versions of gawk may create problems in compilation, because older awks have problems with backslashes at the end of a line. For MSDOS, there a "makefile.dos" that should do the trick. Note: makefile.dos was not tested for a long time. There are also Visual Studio 2013 project files provided by zothrosko. The result of compilation should be a single executable called "btyacc" which you can install anywhere you like; it does not require any other files in the distribution to run.
