Replace common emoji shortnames with unicode as a python-markdown extension

Primary LanguagePython

Python-Markdown UnicodeEmoji extension

A simple hack disguised as an extension to allow common emoji shortnames to be found and replaced in markdown text by the python-markdown engine.

There are many others by potentially more experienced python coders, but the distinguishing feature of this extension is that proper Unicode is used as replacement rather than various forms of images delegating the display task to fonts you have (hopefully) installed on your system.

How to build & run

There are no build steps and as an extension it is to be run by python-markdown only as configured.

The extension requires various data files to function properly. These data files are NOT included in the repository, you may find them in other locations on the web:

See their upstream sites for licensing details and how to use them "properly" as this extension isn't really using them properly. You have been warned. They are also the right place to report bugs if you miss a mapping (and have verified before that it isn't an error on my part that it is missing).

To ensure a browser picks the right fonts for the emoji display it is recommended to provide a hint via CSS (the created span tag wrapping unicode emoji gets the class emoji assigned for this purpose):

.emoji {
  font-family: "Twemoji", "Twemoji Mozilla", "EmojiOne", "EmojiOne Mozilla",
    "JoyPixels", "Apple Color Emoji", "Segoe UI", "Segoe UI Emoji",
    "Segoe UI Symbol", "Noto Color Emoji", "EmojiSymbols", "DejaVu Sans",
    "Symbola";
  /* avoid the splitting of multi-char unicodes */
  white-space: nowrap;
}

If you know of other font families which have reasonable support for the emoji sets feel free to contact me to have them added.

Note that the "graphics" you see and the text strings they are replacing are not part of this repository and might be covered by an entirely different license. The emoji.json dataset from JoyPixels (previously EmojiOne) is e.g. under the MIT license. If you are on Linux and are running Firefox the "graphics" you see are e.g. likely Twemoji released under the CC-BY 4.0. In earlier versions this was an early JoyPixels (back than EmojiOne) released also under CC-BY 4.0, but newer versions have a proprietary license.
