RHINO-JSC(1) General Commands Manual RHINO-JSC(1)
NAME
rhino-jsc - invokes the rhino JavaScript compiler
SYNOPSIS
rhino-jsc [options] file1.js [file2.js...]
DESCRIPTION
This manual page documents briefly the rhino-jsc command. This manual
page was written for the Debian distribution because the original pro-
gram 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 an-
other 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.
OPTIONS
-version versionNumber
Specifies the language version to compile with. The string ver-
sionNumber 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 op-
tionally 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 moni-
tored using Context.setInstructionObserverThreshold.
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
