This was a mirror of the open-source-emoji plugin, which is now closed. It remains here for posterity only.
Gitified version of the Open Source Emoji plugin published in the official Wordpress plugin directory:
http://wordpress.org/plugins/open-source-emoji/
Please report issues in the Wordpress plugin directory support forum:
http://wordpress.org/support/plugin/open-source-emoji
Note that the actual name of the plugin is "open-source-emoji" not "wp-emoji". It's renamed on Github to differentiate it as a Wordpress plugin.
Add the plugin to your Wordpress project via Git as follows:
$ git submodule add https://github.com/timwhitlock/wp-emoji.git \
wp-content/plugins/open-source-emoji
If you want to use a stable release listed in the Wordpress plugin directory, you can checkout by tag, e.g.:
$ cd wp-content/plugins/open-source-emoji
$ git fetch origin
$ git checkout tags/1.0.6
