<p>The list of options is derived from the
<a href="apidocs/net/happygiraffe/jslint/Option.html">Option</a> enum. For fuller
documentation of each option, see the
<a href="http://www.jslint.com/lint.html">jslint web site</a>.</p>
<p>You must pass a number of javascript files on the command line. For each one,
jslint4java will produce a list of errors on stdout. If any errors are found,
an exit code of 1 will be returned.</p>
<p>Sample error output:</p>
<pre>
$ cat dodgy.js
someVar = 42
$ java -jar jslint4java-1.3.jar dodgy.js
jslint:dodgy.js:0:12:Missing semicolon.
$
</pre>
<p>The fields are colon separated and consist of:</p>
<ol>
<li>The fixed string "jslint"</li>
<li>The filename</li>
<li>The line number</li>
<li>The column number</li>
<li>The error</li>
</ol>
<p>Most command line flags are boolean. If you wish to pass a value to a flag
(e.g. <code>--indent</code>), add it using an equals. For example:</p>
<pre>
$ cat happy.js
var x;
if (x) {
x = 42;
}
$ java -jar jslint4java-1.3.jar --white happy.js
jslint:happy.js:2:2:Expected 'x' to have an indentation of 4 instead of 2.
$ java -jar jslint4java-1.3.jar --white --indent=2 happy.js
$
