rhino-jsc - invokes the rhino JavaScript compiler
rhino-jsc [options] file1.js
[file2.js...]
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.
- -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.
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
