Update TinyMCE to 5.X.X

[Presskopp]

TinyMCE Version 5.0.5 has been released on May 9, 2019, see:

​https://www.tiny.cloud/docs/release-notes/release-notes50/
​https://www.tiny.cloud/docs/changelog/

Don't we want to keep it up to date?

It could break things, though, see :

There are no plans (for now) to migrate to TinyMCE 5. Yep, see ​https://www.tiny.cloud/docs/migration-from-4x/.

Any changes to this plan now that we're closing in on v4 EOL?

v5 resolves this bug #51367.

Been looking at/thinking about what are the best options here for a while. The problem is that there is no official "migrate" plugin when upgrading from 4.x to 5.x like the compat3x plugin for migrating (back-compat) from 3.x to 4.x.

There are quite a few API changes in 5.x: renamed methods, deprecated functions and settings, new UI with a bit different HTML stricture and CSS classes, etc. that break backwards compatibility. See: ​https://www.tiny.cloud/docs/migration-from-4x/.

For example, editor.addButton() is perhaps the most used API call in WordPress plugins that add custom TinyMCE plugins. In TinyMCE 5.x this results in an error, see: ​https://github.com/tinymce/tinymce/blob/014d8599bb398168a98e8c9964bc29a394d75cd8/modules/tinymce/src/core/main/ts/api/Editor.ts#L1130. Changes:

TinyMCE 4:

editor.addButton('mybutton', {
  text: 'My Button',
  cmd: 'mceSave'
});

TinyMCE 5:

editor.ui.registry.addButton('myButton', {
  text: 'My Button',
  onAction: function () {
    editor.execCommand('mceSave');
  }
});

(In addition the "button settings" have changed too. There's no more support for cmd, instead a callback function is needed, and there's no onclick, has been renamed to onAction.)

What it will take to upgrade TinyMCE to version 5.x in WordPress?

As far as I see:

• Create a team of (as many of) the authors of WordPress plugins that add TinyMCE code/plugins. The main purpose of the team would be to determine and then test all needed changes to core, and perhaps to "spread the word".
• Make an in-house compat4x plugin for TinyMCE 5.x. Looks like it won't be possible to have "full" compatibility, but most cases of deprecation and renamed functions/methods can be patched/fixed.
• Make a feature plugin with the updated TinyMCE and the above compat plugin.
• Test the feature plugin. Ask "everybody" to test as much as possible to catch edge cases that can be fixed/patched.

I am interested in this as I use TinyMCE for bbPress. I also have my own plugin that adds a couple of plugins to the toolbar functionality.

But, I am not a PHP programming. My knowledge of TinyMCE is limited. I would like to see it supported else I will have serious problems down the road with bbPress. Since TinyMCE authors are cutting off support for v4 at the end of 2020.

[ajtruckle]

Naturally many times the TinyMCE has been updated. Like when it went from 3 to 4. So is it documented where code needs changing? Someone (not me) needs to take charge of any team and direct people on what bit they can do.

It just seems like we are reinventing the wheel a bit. Someone must know what code in WordPress makes use of TinyMCE as a starter. But if not, how do we find out?

Any news with updating to TinyMCE 5?

[herrizal]

there is ​security fixes in tinyMCE v5.1.6 that maybe can help to push tinyMCE update

[ajtruckle]

I hope that support will be added. I simply am not in a position nor have the ability to upgrade it myself but I heavily rely on TinyMCE.

GutenBerg is fine for creating my pages and posts but it is by no means appropriate for something like bbPress where any user would expect u=just a nice toolbar at the top.

Hi,
Any info about update for TinyMCE to version 5?
GutenBerg good for build Page as a page builder, TinyMCE still good for create/update POST and DATA.
Many Plugin still use TinyMCE (WooCommerce etc).
Please update info about this.
Thanks

An update would be much appreciated!
