Description

       This  manual  page  documents briefly the rhino-jsc 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-jsc  is  a  start  script  for  the  rhino  JavaScript compiler. The JavaScript compiler translates
       JavaScript source into Java class files. The resulting Java class files can then be loaded  and  executed
       at  another time, providing a convenient method for transferring JavaScript, and for avoiding translation
       cost.  Note that the top-level functions available to the shell (such as  print)  are  not  available  to
       compiled scripts when they are run outside the shell.

Example

       Example  compiling  the  NervousText.js  applet  written  in  JavaScript.  The example is provided in the
       librhino-java-doc package.

       $ rhino-jsc -extends java.applet.Applet -implements java.lang.Runnable NervousText.js

Name

       rhino-jsc - invokes the rhino JavaScript compiler

Options

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

       -opt, -O optLevel
              Optimizes at level optLevel, which must be an integer between 0 and 9.

       -debug, -g
              Specifies  that debug information should be generated. May not be combined with optimization at an
              optLevel greater than zero.

       -nosource
              Does not save the source in the class file. Functions and scripts  compiled  this  way  cannot  be
              decompiled.  This  option  can be used to avoid distributing source or simply to save space in the
              resulting class file.

       -o outputFile
              Writes the class file to the given file (which should end in .class). The string  outputFile  must
              be a writable filename.

       -package packageName
              Specifies the package to generate the class into. The string packageName must be composed of valid
              identifier characters optionally separated by periods.

       -d outputDirectory
              Uses  outputDirectory  as  destination directory for generated classes. If omitted, it defaults to
              parent directory of the source file.

       -encoding charset
              Sets the character encoding of the source files.

       -extends java_class_name
              Specifies that a java class extending the Java class java_class_name should be generated from  the
              incoming  JavaScript  source file. Each global function in the source file is made a method of the
              generated class, overriding any methods in the base class by the same name.

       -implements java_intf_name
              Specifies that a java class implementing the Java interface  java_intf_name  should  be  generated
              from the incoming JavaScript source file. Each global function in the source file is made a method
              of the generated class, implementing any methods in the interface by the same name.

       -main-method-class className
              Specifies  the  class  name  used  for  main  method  implementation. The class must have a method
              matching public static void main(Script sc, String[] args).

       -observe-instruction-count
              Generates code that contains  callbacks  to  accumulate  counts  of  executed  instructions.  Code
              compiled with this flag can be monitored using Context.setInstructionObserverThreshold.
