https://wordpress.org/plugins/tags/tinymce is about the closest to that.
They aren’t TinyMCE Plugins exactly, but they are plugins that modify or otherwise work with WordPress’s TinyMCE editor.
Not those plugins, the ones tinyMCE uses.
Then no, there is no plugin directory for TinyMCE on WordPress.
I found that question, while working with TinyMCE. I think he wants to know where TinyMCE Plugins are located in a wordpress installation, so I write it here for you, if you havent found it yet, and others:
TinyMCE Plugins are located in:
wp-includes\js\tinymce\plugins
So it is possible for you to place here additional TinyMCE Plugins to add functionality to the WordPress TinyMCE. I added for example the AutoResize function for me here.
To use them it is not enough to place only the plugin here, you will have to use it later in your custom JS code, when you use the Editor in a plugin or expand the default TinyMCE in your plugin.
Ah, thanks for thinking of that differently than I did! 🙂
Mr. Black,
Thank you for your advice. Do you have any instructions on how to add to the custom JS code?
