django-emoji 1.1.0

Quick start

1. Install django-emoji from PyPi:

   pip install django-emoji

2. Add “emoji” to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = (
       ...
       'emoji',
   )

3. Include the emoji URLconf in your project urls.py like this if you want to be able to get a JSON list of emojis:

   url(r'^emoji/', include('emoji.urls')),

4. Visit http://127.0.0.1:8000/emoji/all.json to get a json object with all emojis avilable

API

Python

The Python class Emoji is a singleton and will return the same instance between instantiations. On load Emoji will load the name of all the emjis and their unicode equivalents into memory.

Javascript

The browser version caches all the emojies in localStorage so there won’t be that many roundtrips to the server just to get a list of the emojies.

NOTE: Depends on jQuery or some other library that exports $.get.

Examples

Replace an emoji using Python templates by loading the tags in your template:

{% load emoji_tags %}
{{ blog_post.body|emoji_replace }}
{{ blog_post.body|emoji_replace_unicode }}

Replace emojis using Javascript (to for instance show a preview before the user saves what it is they are writing):

{% load emoji_tags %}

<script src="{% static 'emoji/js/emoji.js' %}"></script>
{% emoji_load %}

Emoji.get('dog') // => url stub to dog emoji or falsy
Emoji.get() // => all emojis available

Emoji.replace("It's raining :cats: and :dogs:.") // => It's raining <img src="..." alt="cats" class="emoji"> and <img src="..." alt="dogs" class="emoji">

What emoji_load does is that it sets the endpoint to retrieve the listing of all the available emojis and thus only works if the emoji urls has been included.

It is the equivalent of doing:

Emoji.setDataUrl('{% url 'emoji:list.json' %}').load();

Which is also available as template stub:

{% include 'emoji/script.html' %}

Usage from inside Python where the Emoji class mimics some of the behavior of a dict:

from emoji import Emoji
Emoji['dog'] # => url stub to dog emoji or None
'dog' in Emoji # => True
Emoji.keys() # => a list of all emojis by name
Emoji.replace("It's raining :cats: and :dogs:") # => It's raining <img src="..." alt="cats" class="emoji"> and <img src="..." alt="dogs" class="emoji">

Replacing unicode Emojis

Emoji has the ability to give you the name of an emoji from a unicode character. It can also replace every instance of emoji characters in a string with their image replacements.

Usage:

>>> from emoji import Emoji
>>> Emoji.name_for(u'\U000148b')
kiss
>>> Emoji.replace_unicode(u'I send a \U0001f48b!')
I send a <img src="/static/emoji/img/kiss.png" alt="kiss" class="emoji">

Note:

To be able to use the unicode replacements your Python version needs to be built with wide unicode character support. This seems to be the case for most Pythons available from package managers. If you do not have wide character support then an exception will be raised:

>>> print(unichr(0x0001f48b))
ValueError: unichr() arg not in range(0x10000) (narrow Python build)
