TYPO3 Core

I added it to the issue tracker of autolink https://github.com/ckeditor/ckeditor-dev/issues/1761 + https://github.com/ckeditor/ckeditor-dev/issues/1815

It seems that this has been solved on March https://github.com/ckeditor/ckeditor-dev/pull/1825

I report here the comment on issue #84500 by Josef Glatz to keep track of it

ckeditor 4.10 is released which contains the change

Thanks for adding the autolink plugin. This is an improvement but linking while typing is the more important feature. Unfortunately the current version of CKEditor 4 is not able to link URLs and email addresses automatically while typing. This feature will probably be available in version 4.11: https://github.com/ckeditor/ckeditor-dev/issues/1815#issuecomment-405965905
So, I guess we have to wait until CKEditor 4.11 is included in TYPO3 or someone develops a custom solution/backports this feature.

For anyone who's in need of a quick solution I wanted to let them know that I've just created a tiny extension that's providing the feature of autolinking mail addresses to the ckeditor.

And yes, it's heavily inspired by the autolink plugin that's already in the core ;-)
