## Installation
```shell
$ pip install django-charsleft-widget
```
### External dependencies

* jQuery - This is not included in the package since it is expected that in most scenarios this would already be available.

## Setup

Add `charsleft_widget` to `INSTALLED_APPS`:
```python
INSTALLED_APPS = [
...
'charsleft_widget',
]
```
and just include `charsleft_widget` templates
```html
{% include "charsleft_widget/charsleft_widget_css.html" %} {# Before the closing head tag #}
{% include "charsleft_widget/charsleft_widget_js.html" %} %} {# Before the closing body tag #}
```
When deploying on production server, don't forget to run :
```shell
$ python manage.py collectstatic
```
## Usage

All you need now is to import ``CharsLeftArea`` class and override field's widget, for example :
```python
import django
if django.VERSION < (1,7):
from charsleft_widget.fields import CharField
else:
from django.forms.fields import CharField

from charsleft_widget import CharsLeftArea


class Form(forms.Form):

field = CharField(max_length=128, widget=CharsLeftArea)
```
Please see `example` application. This application is used to manually test the functionalities of this package. This also serves as a good example.

You need only Django 1.4 or above to run that. It might run on older versions but that is not tested.
