    static function main(argv : string[]) : void
    {
        var stemmer = new EnglishStemmer();
        log stemmer.stemWord("baby"); // babi
    }
}

Use from node.js

var FrenchStemmer = require('snowball-stemmer.jsx/dest/french-stemmer.common.js').FrenchStemmer;

Use from require.js

// use snowball-stemmer.amd.js
define(['german-stemmer.jsx'], function (germanstemmer) {

    var stemmer = new germanstemmer.GermanStemmer();
});

Use via standard JSX function

<script src="spanish-stemmer.js" type="text/javascript"></script>
<script type="text/javascript">
window.onload = function () {
    var SpanishStemmer = JSX.require("lib/spanish-stemmer.js").SpanishStemmer;
    var stemmer = new SpanishStemmer();
});
</script>

Use via global variables

<script src="snowball-stemmer.global.js" type="text/javascript"></script>
<script type="text/javascript">
window.onload = function () {
    var RussianStemmer = new RussianStemmer();
    var stemmer = new RussianStemmer();
});
</script>

Installation

$ npm install snowball-stemmer.jsx

If you want to use this library from other JSX project, install like the following:

$ npm install snowball-stemmer.jsx --save-dev

or add like these lines to your parent project's package.json:

   devDependencies: {
       "snowball-stemmer.jsx": "~0.2.0"
   },
   peerDepenencies: {

Development

JSX

Don't be afraid JSX! If you have an experience of JavaScript, you can learn JSX quickly.

• Static type system and unified class syntax.
• All variables and methods belong to class.
• JSX includes optimizer. You don't have to write tricky unreadalbe code for speed.
• You can use almost all JavaScript API as you know. Some functions become static class functions. See reference.
