Code Input
==========
.. versionadded:: 1.5.0
.. image:: images/codeinput.jpg
.. note::
This widget requires ``pygments`` package to run. Install it with ``pip``.
The :class:`CodeInput` provides a box of editable highlighted text like the one
shown in the image.
It supports all the features provided by the :class:`~kivy.uix.textinput` as
well as code highlighting for `languages supported by pygments
`_ along with `KivyLexer` for
:mod:`kivy.lang` highlighting.
Usage example
-------------
To create a CodeInput with highlighting for `KV language`::
from kivy.uix.codeinput import CodeInput
from kivy.extras.highlight import KivyLexer
codeinput = CodeInput(lexer=KivyLexer())
To create a CodeInput with highlighting for `Cython`::
from kivy.uix.codeinput import CodeInput
from pygments.lexers import CythonLexer
codeinput = CodeInput(lexer=CythonLexer())
