Installation

1. Copy the abbr directory to assets/tinymce4/plugins.

2. Add a new tinyMCE configuration (e.g. tinyAbbr.php) file to system/config/ (e.g. system/config/tinyAbbr.php).

3. Enable the abbreviation plugin in your tinyMCE configuration you just created in step 2 by adding abbr to the plugins list:

   plugins: "autosave charmap code fullscreen image link lists paste searchreplace tabfocus table template visualblocks abbr",
   

4. To make sure this configuration is loaded, you have to adjust the corresponding DCA setting. If you want to enable this configuration for all tinyMCE usages in the backend you can adjust your system/config/dcaconfig.php as follows:

foreach ($GLOBALS['TL_DCA'] as $table => $config) {
    foreach ($config['fields'] as $field => $fieldConfig) {
        if (isset($fieldConfig['eval']['rte'])) {
            $GLOBALS['TL_DCA'][$table]['fields'][$field]['eval']['rte'] = 'tinyAbbr';
        }
    }
}
