mozilla/js/rhino/org is now distributed between mozilla/js/rhino/src and mozilla/js/rhino/toolsrc. The build.xml has been split in three. Docs now live in the project directory. These changes mean that the cvs directories mirror the distribution and thus a distribution will build the same way as a cvs build.

JavaScript Compiler</h1></center>
|
|
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.
|
|
<p>Note that the top-level functions available to the shell (such as <tt>print</tt>)
|
|
are <i>not</i> available to compiled scripts when they are run outside
|
|
the shell.

Invoking the Compiler</h2>
|
|
<tt>java org.mozilla.javascript.tools.jsc.Main</tt> [<i>options</i>] <i>file1</i><tt>.js</tt>
|
|
[<i>file2</i><tt>.js</tt>...]
|
|
<p>where <i>options</i> are:
|
|
<p><tt>-extends <i>java-class-name</i></tt>
|
|
<blockquote>Specifies that a java class extending the Java class <i>java-class-name</i>
|
|
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.</blockquote>
|
|
<tt>-implements <i>java-intf-name</i></tt>
|
|
<blockquote>Specifies that a java class implementing the Java interface
|
|
<i><tt>java-intf-name</tt></i>
|
|
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.</blockquote>
|
|
<tt>-debug</tt>
|
|
<br><tt>-g</tt>
|
|
<ul>Specifies that debug information should be generated. May not be combined
|
|
with optimization at an <i>optLevel</i> greater than zero.</ul>
|
|
<tt>-nosource</tt>
|
|
<ul>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.</ul>
|
|
<tt>-o </tt><i>outputFile</i>
|
|
<ul>Writes the class file to the given file (which should end in <tt>.class</tt>).
|
|
The string <i>outputFile</i> must be a writable filename.</ul>
|
|
<tt>-opt </tt><i>optLevel</i>
|
|
<br><tt>-O</tt> <i>optLevel</i>
|
|
<ul>Optimizes at level <i>optLevel</i>, which must be an integer between
|
|
-1 and 9. See <a href="opt.html">Optimization</a> for more details. If
|
|
<i>optLevel</i>
|
|
is greater than zero, <tt>-debug</tt> may not be specified.</ul>
|
|
<tt>-package</tt> <i>packageName</i>
|
|
<ul>Specifies the package to generate the class into. The string <i>packageName</i>
|
|
must be composed of valid identifier characters optionally separated by
|
|
periods.</ul>
|
|
<tt>-version </tt><i>versionNumber</i>
|
|
<ul>Specifies the language version to compile with. The string <i>versionNumber</i>
|
|
must be one of <tt>100</tt>, <tt>110</tt>, <tt>120</tt>, <tt>130</tt>,
|
|
or <tt>140</tt>. See <a href="overview.html#versions">JavaScript Language
|
|
Versions</a> for more information on language versions.</ul>
