Cool, thanks Marius, I was able to add something that adds a button to the CKEditor by using approximately the following snippet: require(['jquery'], function($) {$(document).ready(function() { if(XWiki.contextaction=='edit') { require(['deferred!ckeditor'], function(ckeditorPromise) { ckeditorPromise.done(function(ckeditor) { ckeditor.on('instanceCreated', function(event) { event.editor.once('configLoaded', function(event) { ckeditor.tools.extend(event.editor.config, { plugins: 'ckeditor_wiris', }, true); }); ckeditor.plugins.addExternal('ckeditor_wiris', '/wiriseditorapp/ckeditor_wiris/plugin.js'); }); }); }); }})}); within CKEditor.EditSheet2 which loads everywhere (I hope syntax-colored html doesn't bother people's reading, it's a present of IntelliJ IDEA). I am sure there are less verbose ways to do it! One thing, however, where this is incomplete is that this only evaluates if XWiki.contextaction=='edit' instead of checking for something more realistic such as the availability of one or several CKeditors. It doesn't trigger errors so it's not too bad (it is because of the promise?). With comments on optimization, I think we should start a snippet page or something such. Now, the content that is created with this plugin (MathML elements) is being killed by the rendering framework. I guess I can either: - let it be wrapped as a macro - adjust the rendering framework to respect that bit I think the second is impossible though. Or? thanks Paul I voted.

Thank you Marius, That has worked very well. Ok The wiris editor I'm trying to integrate produces MathML-islands which, currently, gets removed by the rendering conversion. Is there a good hook at the XWiki or CKEditor level I could bind to, so that I change the content before it gets posted to the conversion? I'd convert the MathML islands to macros which would, depending on the browser, render to MathML or to images. thanks in advance. Paul

Hello Marius, Can you give an example on how to hook it? At least hooking it in the instanceCreated (calling then ckeditor.on( 'toDataFormat', function( evt) { console.log("toDataFormat"); }, null, null, 3 ); did not seem to call it. Should it be called later? One of the alternative possibilities I have is to let the islands be directly converted to a macro-call right after they got edited. This is better for a predictable wysiwyg effect. However how could I let the macro-islands be edited using the wiris plugin instead of the default macro-editor when they are double clicked?? I fear this is not pluggeable. thanks paul

Hi Paul, The CKEditor plugin that handles wiki macros is https://github.com/xwiki-contrib/application-ckeditor/blob/master/plugins/s… . It uses https://github.com/xwiki-contrib/application-ckeditor/blob/master/plugins/s… . Be aware that the macro output is not submitted. You need to update the macro markers. Also node that wiki macros are handles as CKEditor Widgets http://docs.ckeditor.com/#!/guide/widget_sdk_tutorial_1 . Hope this helps, Marius On Wed, Aug 31, 2016 at 5:46 PM, Paul Libbrecht <paul(a)hoplahup.net> wrote:
