Polished-up version of cosmocode/dokuwiki-plugin-prosemirror, part of the dokuwiki-preconfigured project.
The main aim of this fork is to make the editing experience as seamless as possible. This mostly means getting rid of small annoyances. I probably won't do any serious work on the actual core, since that is already quite solid. Thanks to Cosmocode for doing the hard part!
Extension Manager -> Manual install with URL https://github.com/fablab-luenen/dokuwiki-visual-editor/zipball/release (or manually extract it into /lib/plugins/prosemirror).
In case your theme has a fixed header, you can configure the toolbar to stick below it while scrolling with the following CSS in userstyle.css:
/* Make menubar stick below header */
.editBox .prosemirror_wrapper .menubar {
top: 5em; /* Height of your header */
}
Refer to the original project for information about the architecture.
Also note that DokuWiki caches scripts. For changes to show up you can edit scripts.js or disable caching.
