=====

Release v\ |version|. (:ref:`Installation <install>`)

emoji supports Python 2.7 and 3.4+

.. contents:: Table of Contents

Usage and Examples
------------------

The main purpose of this package is converting Unicode emoji to emoji names and vice
versa with :func:`emojize` and :func:`demojize`.

The entire set of Emoji codes as defined by the `Unicode consortium <https://unicode.org/emoji/charts/full-emoji-list.html>`__
is supported in addition to a bunch of `aliases <https://www.webfx.com/tools/emoji-cheat-sheet/>`__.
By default, only the official list is enabled but doing ``emoji.emojize(language='alias')``
enables both the full list and aliases.


.. doctest::

    >>> print(emoji.emojize('Python is :thumbs_up:'))
    Python is 👍
    >>> print(emoji.emojize('Python is :thumbsup:', language='alias'))
    Python is 👍
    >>> print(emoji.demojize('Python is 👍'))
    Python is :thumbs_up:
    >>> print(emoji.emojize("Python is fun :red_heart:", variant="text_type"))
    Python is fun ❤︎
    >>> print(emoji.emojize("Python is fun :red_heart:", variant="emoji_type"))
    Python is fun ❤️

..

Languages
^^^^^^^^^

By default, the language is English (``language='en'``) but  also supported languages are:

Spanish (``'es'``), Portuguese (``'pt'``), Italian (``'it'``), French (``'fr'``), German (``'de'``), Farsi/Persian (``'fa'``)

.. doctest::

    >>> print(emoji.emojize('Python es :pulgar_hacia_arriba:', language='es'))
    Python es 👍
    >>> print(emoji.demojize('Python es 👍', language='es'))
    Python es :pulgar_hacia_arriba:
    >>> print(emoji.emojize("Python é :polegar_para_cima:", language='pt'))
    Python é 👍
    >>> print(emoji.demojize("Python é 👍", language='pt'))
    Python é :polegar_para_cima:

..

Extracting emoji
^^^^^^^^^^^^^^^^

The function :func:`emoji_list` finds all emoji in string and their position.
Keep in mind that an emoji can span over multiple characters:

.. doctest::

    >>> emoji.emoji_list('Python is 👍')
    [{'match_start': 10, 'match_end': 11, 'emoji': '👍'}]
    >>> emoji.emoji_list('A 👩‍🚀 aboard a 🚀')
    [{'match_start': 2, 'match_end': 5, 'emoji': '👩‍🚀'}, {'match_start': 15, 'match_end': 16, 'emoji': '🚀'}]

..

To retrieve the distinct set of emoji from a string, use :func:`distinct_emoji_list`:

.. code-block:: python

    >>> emoji.distinct_emoji_list('Some emoji: 🌍, 😂, 😃, 😂, 🌍, 🌦️')
    ['😃', '😂', '🌦️', '🌍']

..

To count the number of emoji in a string, use :func:`emoji_count`:

.. doctest::

    >>> emoji.emoji_count('Some emoji: 🌍, 😂, 😃, 😂, 🌍, 🌦️')
    6
    >>> emoji.emoji_count('Some emoji: 🌍, 😂, 😃, 😂, 🌍, 🌦️', unique=True)
    4

..

You can check if a string is a single, valid emoji with :func:`is_emoji`

.. doctest::

    >>> emoji.is_emoji('🌍')
    True
    >>> emoji.is_emoji('🌍😂')
    False
    >>> emoji.is_emoji('test')
    False

..


To get more information about an emoji, you can look it up in the :data:`EMOJI_DATA` dict:

.. testcode::

    pprint(emoji.EMOJI_DATA['🌍'])

..

.. testoutput::

    {'E': 0.7,
     'alias': [':earth_africa:'],
     'de': ':globus_mit_europa_und_afrika:',
     'en': ':globe_showing_Europe-Africa:',
     'es': ':globo_terráqueo_mostrando_europa_y_áfrica:',
     'fr': ':globe_tourné_sur_l’afrique_et_l’europe:',
     'it': ':europa_e_africa:',
     'pt': ':globo_mostrando_europa_e_áfrica:',
     'status': 2,
     'variant': True}

..

``'E'`` is the :ref:`Emoji version <Emoji version>`.

``'status'`` is defined in :data:`STATUS`. For example ``2`` corresponds
to ``'fully_qualified'``. More information on the meaning can be found in the
Unicode Standard http://www.unicode.org/reports/tr51/#Emoji_Variation_Selector_Notes


Replacing and removing emoji
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

With :func:`replace_emoji` you can replace, filter, escape or remove emoji in a string:

.. code-block:: python

    >>> emoji.replace_emoji('Python is 👍', replace='')
    'Python is '

    >>> emoji.replace_emoji('Python is 👍', replace='👎')
    'Python is 👎'

    >>> def unicode_escape(chars, data_dict):
    >>>     return chars.encode('unicode-escape').decode()
    >>> emoji.replace_emoji('Python is 👍', replace=unicode_escape)
    'Python is \U0001f44d'

    >>> def xml_escape(chars, data_dict):
    >>>     return chars.encode('ascii', 'xmlcharrefreplace').decode()
    >>> emoji.replace_emoji('Python is 👍', replace=xml_escape)
    'Python is &#128077;'

    >>> emoji.replace_emoji('Python is 👍', replace=lambda chars, data_dict: chars.encode('ascii', 'namereplace').decode())
    'Python is \N{THUMBS UP SIGN}'

    >>> emoji.replace_emoji('Python is 👍', replace=lambda chars, data_dict: data_dict['es'])
    'Python is :pulgar_hacia_arriba:'

..

Emoji versions
^^^^^^^^^^^^^^

The parameter ``version`` in :func:`replace_emoji` allows to replace only emoji above
that :ref:`Emoji version <Emoji version>` to prevent incompatibility with older platforms.

For the functions :func:`emojize` and :func:`demojize` the parameter ``version`` will
replace emoji above the specified version with the value of the parameter ``handle_version``.
It defaults to an empty string, but can be set to any string or a function that returns a string.

For example the ``:croissant:`` 🥐 emoji was added in Emoji 3.0 (Unicode 9.0) in 2016 and
``:T-Rex:`` 🦖 was added later in Emoji 5.0 (Unicode 10.0) in 2017:

.. doctest::

    >>> emoji.replace_emoji('A 🦖 is eating a 🥐', replace='[Unsupported emoji]', version=1.0)
    'A [Unsupported emoji] is eating a [Unsupported emoji]'

    >>> emoji.replace_emoji('A 🦖 is eating a 🥐', replace=lambda chars, data_dict: data_dict['en'], version=3.0)
    'A :T-Rex: is eating a 🥐'

    >>> emoji.emojize('A :T-Rex: is eating a :croissant:', version=3.0)
    'A  is eating a 🥐'

    >>> emoji.emojize('A :T-Rex: is eating a :croissant:', version=3.0, handle_version='[Unsupported emoji]')
    'A [Unsupported emoji] is eating a 🥐'

    >>> emoji.demojize('A 🦖 is eating a 🥐', version=3.0)
    'A  is eating a :croissant:'

    >>> emoji.replace_emoji('A 🦖 is eating a 🥐', replace='', version=5.0)
    'A 🦖 is eating a 🥐'

..

You can find the version of an emoji with :func:`version`:

.. doctest::

    >>> emoji.version('🥐')
    3
    >>> emoji.version('🏌️‍♀️')
    4
    >>> emoji.version('🦖')
    5
..


Migrating to version 2.0.0
--------------------------

There a two major, breaking changes in version 2.0.0

non-English short codes
^^^^^^^^^^^^^^^^^^^^^^^

The names of emoji in non-English languages have changed, because the data files were updated to
the new version 41. See https://cldr.unicode.org/index/downloads.

That means some ``:short-code-emoji:`` with non-English names will no longer work in 2.0.0.
:func:`emojize` will ignore the old codes.

This may be a problem if you have previously stored ``:short-code-emoji:`` with non-English names
for example in a database or if your users have stored them.

Regular expression
^^^^^^^^^^^^^^^^^^

The function ``get_emoji_regexp()`` was removed in 2.0.0. Internally the module no longer uses
a regular expression when scanning for emoji in a string (e.g. in :func:`demojize`).

The regular expression was slow in Python 3 and it failed to correctly find certain combinations
of long emoji (emoji consisting of multiple Unicode codepoints).

If you used the regular expression to remove emoji from strings, you can use :func:`replace_emoji`
as shown in the examples above.

If you want to extract emoji from strings, you can use :func:`emoji_list` as a replacement.

If you want to keep using a regular expression despite its problems, you can create the
expression yourself like this:

.. testcode::

    import re
    import emoji

    def get_emoji_regexp():
        # Sort emoji by length to make sure multi-character emojis are
        # matched first
        emojis = sorted(emoji.EMOJI_DATA, key=len, reverse=True)
        pattern = u'(' + u'|'.join(re.escape(u) for u in emojis) + u')'
        return re.compile(pattern)

    exp = get_emoji_regexp()
    print(exp.sub(repl='[emoji]', string=u'A 🏌️‍♀️ is eating a 🥐'))
..

Output:

.. testoutput::

    A [emoji] is eating a [emoji]

..


Common problems
---------------

.. code-block::

    UnicodeWarning: Unicode unequal comparison failed to convert both arguments to Unicode - interpreting them as being unequal

..

This exception is thrown in Python 2.7 if you passed a ``str`` string instead of a
``unicode`` string.
You should only pass Unicode strings to this module.

See https://python.readthedocs.io/en/v2.7.2/howto/unicode.html#the-unicode-type for more
information on Unicode in Python 2.7.
