NAME

       jflex - a lexical analyzer generator (also known as scanner generator) for Java

SYNOPSIS

       jflex <options> <input-files>

DESCRIPTION

       JFlex is a lexical analyzer generator (also known as scanner generator) for Java(tm), written in Java(tm). It is also a rewrite of the very
       useful tool JLex. JFlex is designed to work together with the LALR parser generator  CUP,  and  the  Java  modification	of  Berkeley  Yacc
       BYacc/J. It can also be used together with other parser generators like ANTLR or as a standalone tool.

OPTIONS

       -d <directory>
	      write generated file to <directory>

       --skel <file>
	      use external skeleton <file>

       --switch, --table, --pack
	      set default code generation method

       --jlex strict JLex compatibility

       --nomin
	      skip minimization step

       --nobak
	      don't create backup files

       --dump display transition tables

       --dot  write graphviz .dot files for the generated automata (alpha)

       --verbose, -v
	      display generation progress messages (default)

       --quiet, -q
	      display errors only

       --time display generation time statistics

       --version
	      print the version number of this copy of jflex

       --info print system + JDK information

       --help, -h
	      print this message

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 skele-
		     ton.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.
