This is a fork of the original snowball repo where the snowball stemmer (english only) is compiled into Javascript asm with Emscripten for use in the browser.
You can see a demo at https://e2fyi.github.io/snowball/.
For purely front-end work, you can use bower to get the js file.
bower install --save e2fyi/Snowball
The main js file is located at /emscripten/build/snowball_en.js. You will need to load this script and run the module Snowball.
<script src="./emscripten/build/snowball_en.js"></script>// init the module
Snowball();The stemmer is available under the function ElasticMeow.stemmer.snowball. In order to reduce overheads, the stemmer can take in either a space separated string of words or an array of words, instead of a single word.
The stemmer return an output of the same type as the input (i.e. String[] will return String[], String will return String).
Space-separated strings
// stem a whitespace separated string .
// return a string of whitespace separated string.
var stemmed = ElasticMeow.stemmer.snowball('happy going swimming');
// outputs 'happi go swim'
console.log(stemmed);Array of strings
// stem an array of words and return an array of stemmed words.
var stemmed = ElasticMeow.stemmer.snowball(['happy', 'going', 'swimming']);
// outputs ['happi', 'go', 'swim']
console.log(stemmed);You will need to install Emscripten and all the dependencies.
Then you need to make libstemmer and various source files.
make
Then to compile the module.
