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

       Yacc - an LALR(1) parser generator for Java

SYNOPSIS

       byaccj [ -dlrtvJ ] [ -b prefix ] [-Jclass= classname ] [-Jpackage= package_name ] [-Jextends= extends_name ] [-Jimplements= implements_name
       ] [-Jsemantic= semantic_type ] [-Jnorun] [-Jnocontruct] [-Jstack= NNN ] [-Jnodebug] [-Jfinal] [-Jthrows= exception_list ] filename

DESCRIPTION

       Yacc 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 written in the C programming language.  Yacc normally writes the parse tables and the driver routine to
       the file y.tab.c.

       The following options are available:

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

	      -d     The -d option causes the header file y.tab.h to be written.

	      -l     If  the  -l  option  is  not specified, yacc will insert The generated code to the user's original code.  If the -l option is
		     specified, yacc will not insert the .TP -r The -r option causes yacc to produce separate files for code and tables.  The code
		     file is named y.code.c, and the tables file is named y.tab.c.

	      -t     The  -t option changes the preprocessor directives generated by yacc so that debugging statements will 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.

	      -J     The -J option switches from C/C++ to Java output. Not necessary if other -J flags are used.

	      -Jclass=<classname>
		     Changes the name of the Java class (and .java file) to classname

	      -Jpackage=<packagename>
		      Changes the package in which the parser resides from the default <nothing> to packagename

	      -Jextends=<extend_name>
		      Changes the class the parser extends from the default <nothing> to extend_name

	      -Jimplements=<implement_name>
		      Changes the interface the parser implements from the default <nothing> to implement_name

	      -Jsemantic=<semantic_type>
		       Changes the semantic (value of the rules' variables) type to semantic_type.  No extra class will be generated.

	      -Jnorun
		     The -Jnorun option informs Byacc to not generate a run() method. Useful when working with threads.

	      -Jnoconstruct
		     The -Jnoconstruct option informs Byacc to not generate constructors. Useful when extending classes.

	      -Jstack=<NNN>
		      Changes the stack size from default 500 to NNN

	      -Jnodebug
		     The -Jnodebug option informs Byacc to omit debugging code for further better performance.

	      -Jfinal
		     The -Jfinal option makes generated class final.

	      -Jthrows=<exception_list>
		      Informs Byacc to declare thrown exceptions for yyparse() method.

       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

       y.code.c
       y.tab.c
       y.tab.h
       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.
