NAME

       jay - an LALR(1) parser generator for Java and C#

SYNOPSIS

       jay [ -tv ] [ -c ] [ -p ] [ -b file_prefix ] [ -V yyValue ] filename < skeleton

DESCRIPTION

       Jay  reads  the  grammar  specification  in  the file filename and generates an LR(1) parser for it.  The
       parsers consist of a set of LALR(1) parsing tables and a driver routine from the file skeleton written in
       the Java programming language.  Jay writes the parse tables and the driver routine to standard output.

       The following options are available:

              -b file_prefix
                     The  -b  option changes the prefix prepended to the output file names to the string denoted
                     by file_prefix.  The default prefix is the character y.

              -c     The -c option makes jay generate C# code instead of the default Java.

              -t     The -t option arranges for debugging information to be incorporated in the compiled code.

              -v     The -v option causes a human-readable description of the generated parser to be written  to
                     the file y.output.

              -p     The  -p  option  causes  jay  to print the directory in which its sample skeleton files are
                     installed.  If a project wants to use the default skeleton file included with jay,  it  can
                     use this option in a makefile to find the path to the skeleton or skeleton.cs file included
                     with the jay distribution.

       If the environment variable TMPDIR is set, the string denoted by TMPDIR will be used as the name  of  the
       directory where the temporary files are created.

FILES

       skeleton
       y.output
       /tmp/yacc.aXXXXXX
       /tmp/yacc.tXXXXXX
       /tmp/yacc.uXXXXXX

DIAGNOSTICS

       If  there  are  rules that are never reduced, the number of such rules is reported on standard error.  If
       there are any LALR(1) conflicts, the number of conflicts is reported on standard error.

HISTORY

       Jay is derived from Berkeley yacc .  Input conventions closely  follow  those  of  yacc  ;  for  details,
       consult the parser skeleton file and the commented example included with the sources.
