==========

`Build Status <https://travis-ci.org/bung87/whatlangid>`__
`PyPI <https://pypi.python.org/pypi/whatlangid>`__

This project is build on top of
`whatthelang <https://github.com/indix/whatthelang>`__ and
`langid <https://github.com/saffsd/langid.py>`__


Why this project exist?
=======================

see `issue_lang.py <issue_lang.py>`__

Dependencies
------------

The dependencies can be installed using the requirements.txt file:

.. code:: bash

   $ pip install -r requirements.txt

Install
-------

from github

.. code:: bash

   $ pip install  git+https://github.com/bung87/whatlangid  

from pypi

.. code:: bash

   $ pip install  whatlangid  

Basic Usage
-----------

Predicting Language using ``whatlangid``

.. code:: python

   >>> from whatlangid import WhatLangId
   >>> wtl = WhatLangId()
   >>> wtl.predict_lang("Mother")
   'en'
   >>> wtl.predict_lang("தாய்")
   'ta'
   >>> wtl.predict_lang("അമ്മ")
   'ml'
   >>> wtl.predict_lang("पिता")
   'hi'
   >>> wtl.predict_pro(["English sentence", "അമ്മ"])
   [('en', 0.8848170638084412), ('ml', 0.9535570740699768)]

Batch Prediction is also supported

.. code:: python

   >>>wtl.predict_lang(["അമ്മ","पिता","teacher"])
   ['ml','hi','en']

Advanced usage
--------------

``wtl = WhatLangId(custom_model=abs_path)``

use bin version model which is faster and slightly more accurate, but
has a file size of 126MB

``python -m whatlangid.use_bin``

Supported Languages
-------------------

Supports 176 languages . The ISO codes for the corresponding languages
are as below.
