NAME

       jtb - syntax tree builder for JavaCC

SYNOPSIS

       jtb [options] inputfile

DESCRIPTION

       This manual page documents briefly the jtb command.

       JTB (Java Tree Builder) is a syntax tree builder and visitors generator to be used in front of JavaCC (Java Compiler Compiler).	It takes a
       JavaCC grammar file as input (usually a ".jtb" file) and automatically generates the following:

	      - a set of syntax tree classes based on the productions in the grammar, utilizing the Visitor design pattern;

	      - four interfaces: IVoidVisitor, IVoidArguVisitor, IRetVisitor, IRetArguVisitor;

	      - four depth-first visitors: DepthFirstVoidVisitor, DepthFirstVoidArguVisitor, DepthFirstRetVisitor, DepthFirstREtArguVisitor, whose
	      default  methods simply visit the children of the current node; a JavaCC grammar ".jj" file (jtb.out.jj by default), with the proper
	      annotations to build the syntax tree during parsing (which then must be compiled with JavaCC).

       New visitors, which subclass any generated one, can then override the default methods and perform various operations on and manipulate  the
       generated syntax tree.

OPTIONS

       -cl    Print a list of the classes generated to standard out.

       -d dir "-d dir" is short for (and overwrites) "-nd dir/syntaxtree -vd dir/visitor".

       -dl    Generate depth level info.

       -e     Suppress JTB semantic error checking.

       -f     Use descriptive node class field names.

       -h     Display this help message and quit.

       -ia    Inline visitors accept methods on base classes.

       -jd    Generate JavaDoc-friendly comments in the nodes and visitor.

       -nd NAME
	      Use NAME as the package for the syntax tree nodes.

       -np NAME
	      Use NAME as the package for the syntax tree nodes.

       -ns NAME
	      Use NAME as the class which all node classes will extend.

       -o NAME
	      Use NAME as the filename for the annotated output grammar.

       -p NAME
	      "-p pkg" is short for (and overwrites) "-np pkg.syntaxtree -vp pkg.visitor".

       -pp    Generate parent pointers in all node classes.

       -printer
	      Generate a syntax tree dumping visitor.

       -si    Read from standard input rather than a file.

       -scheme
	      Generate Scheme records representing the grammar and a Scheme tree building visitor.

       -tk    Generate special tokens into the tree.

       -vd NAME
	      Use NAME as the package for the default visitor classes.

       -vp NAME
	      Use NAME as the package for the default visitor classes.

       -w     Do not overwrite existing files.
