How to use

Simple analyze

Create Mecab.Tagger instance and call parse() method. You can get a result as string. Mecab.Tagger constuctor arguments is same as executable mecab command line interface.

var MeCab = require('mecab-binding');
var m = new MeCab.Tagger('-O wakati');
console.log(m.parse('今日もしないとね'));

This is similar to other language binding. http://mecab.sourceforge.net/bindings.html

Get more information for each word

When you call parseToNode() method, you can get special morpheme as Mecab.Node instance.

var MeCab = require('mecab-binding');
var m = new MeCab.Tagger('');

var n = m.parseToNode('今日もしないとね');
for (; n; n = n.next()) {
	console.log("%s\t%d", n.feature, n.cost);
}

Currently, node.surface value cannot get correctly.

Error handling

If error has occurred, mecab-binding throws Error. So, if you want to handle it, write try-catch block.

var MeCab = require('mecab-binding');

try {
	var m = new MeCab.Tagger('-d .');
	console.log(m.parse('今日もしないとね'));
} catch (e) {
  console.log('Illegal argument error occurred.');
	console.log(e);
}
