Is it possible to add translation to smiley alt and title in CKEditor?

Question

I'm using Drupal 7 with CKEditor module which permit to insert smiley from editor. I've found that the source code of CKEditor fix the smiley description in JS :

config.smiley_descriptions = [
    'smiley', 'sad', 'wink', 'laugh', 'frown', 'cheeky', 'blush', 'surprise',
    'indecision', 'angry', 'angel', 'cool', 'devil', 'crying', 'enlightened', 'no',
    'yes', 'heart', 'broken heart', 'kiss', 'mail'
];

So when I insert a smiley, the code will be

<img alt="laugh" height="23" src="//cdn.ckeditor.com/4.4.3/full-all/plugins/smiley/images/teeth_smile.png" title="laugh" width="23">

But I want to modify the language of alt and title attributs according to the language used in my site. Is it possible to do that? Thanks in advance.

Never tried but I'm pretty sure that's possible.

If you use the ckeditor module, you can alter JS settings through PHP with hook_ckeditor_settings_alter.

Knowing that, it becomes pretty easy to wrap all strings with the t() function:

function yourmodule_ckeditor_settings_alter(&$settings, $conf) {
  foreach ($settings['smiley_descriptions'] as $key => $smiley) {
    $settings['smiley_descriptions'][$key] = t($settings['smiley_descriptions'][$key]);
  }
}

If you use the wysiwyg_ckeditor module, you can use hook_wysiwyg_plugin. That's pretty much the same thing, you can find a pretty good example on how to use this hook here.

Again, the code hasn't been tested, but it should be a good starting point ;).
