retext implementation of the Porter stemming algorithm.

Installation

npm:

$ npm install retext-porter-stemmer

Component:

$ component install wooorm/retext-porter-stemmer

Bower:

$ bower install retext-porter-stemmer

Usage

var Retext = require('retext'),
    visit = require('retext-visit'),
    porterStemmer = require('retext-porter-stemmer'),
    retext;

retext = new Retext()
    .use(visit)
    .use(porterStemmer)

retext.parse('A simple english sentence.', function (err, tree) {
    tree.visitType(root.WORD_NODE, function (node) {
        console.log(node.toString(), node.data.stem);
    });
    /**
     * 'A', 'A'
     * 'simple', 'simpl'
     * 'english', 'english'
     * 'sentence', 'sentenc'
     */
});

The above example uses retext 0.2.0, which is currently in beta. For an example with the stable retext, see retext-porter-stemmer@0.1.0.

API

None, the plugin automatically stems each word (using wooorm/stemmer) when it’s created or changed, and stores the stem in wordNode.data.stem.
