Django-keyboard-shortcuts
=========================

**Helps to use the keyboard inside your web project**

The project code and bugtracker is hosted on
`Bitbucket `_ and `Github `_.

The only dependency is Django itself
------------------------------------
Just **install**, **configure**, and you are ready to **dominate the world** with your website keyboard shortcuts.

100% test coverage for every bit of code!
-----------------------------------------
**./manage.py test keyboard_shortcuts** coverage output::

Don't uses any javascript framework!
------------------------------------

On the client side you will have only pure javascript code that receives all pre-elaborated and optimized data directly from django.

============
Installation
============

There are a few different ways to install keyboard_shortcus:

Using pip
---------
If you have pip install available on your system, just type::

    pip install django-keyboard-shortcuts

If you've already got an old version of keyboard_shortcus, and want to upgrade, use::

    pip install -U django-keyboard-shortcuts

Installing from a directory
---------------------------
If you've obtained a copy of keyboard_shortcus using either Mercurial or a downloadable
archive, you'll need to install the copy you have system-wide. Try running::

    python setup.py develop

If that fails, you don't have ``setuptools`` or an equivalent installed;
either install them, or run::

    python setup.py install


==============================
How to use keyboard_shortcuts?
==============================

If you have already installed keyboard_shortcus, you must proceed with the
configuration of your project.

Configuration
-------------
very simple, in three steps:

#. Add **keyboard_shortcuts** To INSTALLED_APPS

#. Modify Your settings.py, declare your **HOTKEYS** settings.

#. Add **{% load hotkeys %}{% setup_hotkeys %}** in your template.

Below the long explanation of each step...

Add keyboard_shortcuts To INSTALLED_APPS
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
As with most Django applications, you should add **keyboard_shortcuts** to the INSTALLED_APPS within your settings file (usually *settings.py*).

Example::

    INSTALLED_APPS = [
        'django.contrib.admin',
        'django.contrib.auth',
        'django.contrib.contenttypes',
        'django.contrib.sessions',
        'django.contrib.sites',

        # Added.
        'keyboard_shortcuts',
    ]

Modify Your settings.py
^^^^^^^^^^^^^^^^^^^^^^^

Within your *settings.py*, you’ll need to add some settings in order to assign to desired keyboard shortcuts some actions and to personalize the **django-keyboard-shortcuts** behaviour for your project.

You can define:

- **HOTKEYS** - a list containing the desired keyboard combinations and some settings for each (*default:* **list()**)
- **SPECIAL_DISABLED** - a bool, to disable shortcuts in some "**special cases**", when an input, a textarea or a select is active (*default:* **True**)

Example::

    # START keyboard_shortcuts settings #
    HOTKEYS = [
                {'keys': 'g + h',  # go home
                'link': '/'},
                {'keys': 'g + j',  # go home
                'js': 'javascript_code();'},
            ]
    SPECIAL_DISABLED = True
    # END keyboard_shortcuts settings #

More about HOTKEYS setting?
"""""""""""""""""""""""""""

HOTKEYS is a list of dictioanaries. Each dictionary contains the attributes for a particular keyboard combination. HOTKEYS dist must have a key called "**keys**" and one of "**link**" or "**js**".

Examples of "**keys**" value:

- "CTRL + R"

- "Z + R + P"

- "3 (NUMPAD)"

- "CTRL + \*"

- "="

Examples of "**link**" value:

- "/about/"

- "http://google.com"

Examples of "**js**" value:

- "alert('HELLO!');"

if for a keyboard combination we have both "**link**" and "**js**" declared, only "**link**" will be condidered.

Another advanced examples for **HOTKEYS** list::

    HOTKEYS = [
                {'keys': 'ctrl+h',  # home
                'link': '/',
                },
                {'keys': 'alt+w',
                'link': '/workspace/',
                },
                {'keys': 'shift+j',
                'js': 'js_function();', # javascript code here
                },
                {'keys': 'a+j',
                'js': 'alert(\'A+J Pressed!\');', # javascript code here
                },
                {'keys': '1+2+3',
                'link': '/secret-url/',
                },
            ]

Setup Hotkeys In Your Template
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Now all you need to do is to add **{% load hotkeys %}** and **{% setup_hotkeys %}** in yout template, and *django-keyboard-shortcuts* will do the rest for you... add event listeners and attend for any keypress.

The easiest way to do this is to load hotkeys **{% load hotkeys %}** at the **top** of your "base" template and to setup **{% setup_hotkeys %}** the in your **** section.

Example of "base.html" template::

    {% load hotkeys %}
    
        
            
            {% setup_hotkeys %}
        
        
            my content...
