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 transfering JavaScript, and for
avoiding translation cost.
The JavaScript compiler is not available as free source.
Invoking the Compiler
java com.netscape.javascript.tools.jsc.Main [options] file1.js
[file2.js...]
where options are:
-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.
-opt optLevel
-O optLevel
Optimizes at level optLevel, which must be an integer between
-1 and 9. See Optimization for more details. If
optLevel is greater than zero, -debug may not be specified.
-package packageName
Specifies the package to generate the class into. The string packageName
must be composed of valid identifier characters optionally separated by
periods.
-version versionNumber
Specifies the language version to compile with. The string versionNumber
must be one of 100, 110, 120, 130,
or 140. See JavaScript Language
Versions for more information on language versions.
Example
$ cat test.js
java.lang.System.out.println("hi, mom!");
$ java com.netscape.javascript.tools.jsc.Main test.js
$ ls *.class
test.class
$ java test
hi, mom!
