node-mecab
==========

node-mecab is a very simple MeCab binding for Node.
Not all features are supported now.

Requirement
===========

- Node.js >= 0.4.0
- MeCab >= 0.9.7

How to install
==============

You can install mecab-binding from npm repository.

npm install mecab-binding

You can also make it yourself.

git clone git://github.com/hakobera/node-mecab-binding
	cd node-mecab-binding
	npm install -g
	npm link

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.

Mecab.Taggerhttp://mecab.sourceforge.net/mecab.html constuctor arguments is same as executable mecab command line interface listed below.

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. If your focus is on surface and feature information, you can either use the parse() or the new parseToArray() method:

var arr = m.parseToArray('今日もしないとね');
	for (var i = 0; i < arr.length; i += 2) {
		console.log('Surface: %s\tFeature: %s', arr[i], arr[i + 1]);
	}

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);
	}
