NAME

       rhino - invokes the JavaScript shell for running scripts in batch mode or interactive

SYNOPSIS

       rhino [options] script_filename_or_url [script_arguments]

DESCRIPTION

       This  manual  page  documents  briefly  the  rhino  command.  This manual page was written for the Debian
       distribution because the original program does not have a manual page. It is  written  according  to  the
       html documentation.

       rhino  is  a  start  script  for the rhino JavaScript shell which provides a simple way to run scripts in
       batch mode or an interactive environment for exploratory programming.

OPTIONS

       -w     Enable warnings.

       -version versionNumber
              Specifies the language version to compile with. The string versionNumber must be one of 100,  110,
              120, 130, 140, 150, 160, 170, 180 or 200. See JavaScript Language Versions for more information on
              language versions.

       -opt, -O optLevel
              Optimizes at level optLevel, which must be an integer between -1 and 9. -1 means Interpretive mode
              is always used. 0 means no optimizations whereas 9 means all optimizations are performed.

       -f script_filename_or_url
              Reads script_filename_or_url content and execute it as a JavaScript script.

       -e script_source
              Executes script_source as a JavaScript script.

       -modules uri
              Add a single path or URL element to the CommonJS module search path. (implies -require)

       -require
              Enable CommonJS module support.

       -sandbox
              Enable CommonJS sandbox mode. (implies -require)

       -debug Generate debug code.

       -strict
              Enable strict mode.

       -fatal-warnings
              Treat warnings as errors.

       -encoding charset
              Use specified character encoding as default when reading scripts.

PREDEFINED PROPERTIES

       Scripts executing in the shell have access to some additional properties of the top-level object.

       arguments
              The  arguments object is an array containing the strings of all the arguments given at the command
              line when the shell was invoked.

       help() Executing the help function will print usage and help messages.

       defineClass(className)
              Define an extension  using  the  Java  class  named  with  the  string  argument  className.  Uses
              ScriptableObject.defineClass() to define the extension.

       deserialize(filename)
              Restore from the specified file an object previously written by a call to serialize.

       load([filename,...])
              Load JavaScript source files named by string arguments. If multiple arguments are given, each file
              is read in and executed in turn.

       loadClass(className)
              Load and execute the class named by the string argument className. The class must be a class  that
              implements the Script interface, as will any script compiled by jsc.

       print([expr...])
              Evaluate  and  print  expressions. Evaluates each expression, converts the result to a string, and
              prints it.

       readFile(path[,characterCoding])
              Read given file and convert its bytes to a string using the specified character coding or  default
              character coding if explicit coding argument is not given.

       readUrl(url[,characterCoding])
              Open  an input connection to the given string url, read all its bytes and convert them to a string
              using the specified character coding or default character coding if explicit  coding  argument  is
              not given.

       runCommand(commandName,[arg,...][options])
              Execute the specified command with the given argument and options as a separate process and return
              the    exit    status     of     the     process.     For     details,     see     JavaDoc     for
              org.mozilla.javascript.tools.shell.Global#runCommand.

       serialize(object,filename)
              Serialize the given object to the specified file.

       spawn(functionOrScript)
              Run the given function or script in a different thread.

       sync(function)
              creates  a  synchronized  function  (in  the sense of a Java synchronized method) from an existing
              function. The new function synchronizes on the this object of its invocation.

       quit() Quit shell. The shell will also quit in interactive mode if an end-of-file character is  typed  at
              the prompt.

       version([number])
              Get  or  set  JavaScript version number. If no argument is supplied, the current version number is
              returned. If an argument is supplied, it is expected to be one of 100, 110, 120, 130,  or  140  to
              indicate JavaScript version 1.0, 1.1, 1.2, 1.3, or 1.4 respectively.
