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.
