How to get line wrapping working in codemirror (source highlight) plugin for CKEditor (Sourcebutton)

Sven Schaetzl asked on January 19, 2017 14:30

Hello, we are using Kentico 9.0.47 and have enabled codemirror-Plugin for CKEditor as outlined here:

Kentico Documentation

Unfortunately we don't get the linewrapping enabled which makes editing of HTML-Text (even with codemirror) a real pain. Because all HTML-Text is often in one line and we have to scroll horizontally a lot to find the place to make a change.

Linewrapping is even forced inside of this file (at all occurences):


line 28: lineWrapping: true,

line 79: lineWrapping: true,

line 707: lineWrapping: true,

Hopefully somebody got this to work already and can tell me about what to do to get this running!

Bye Sven

Are there any console errors (javascript errors) that may reveal what is wrong?

It may word wrap using a special tag perhaps, which you may need to inspect and find that "word wrap" tag and adjust it's css if it's being overridden to a point where it's not wrapping.

Never used the plugin, but those are my guesses!

Simply change

    .cke_reset_all .CodeMirror-scroll * {
    white-space: pre;

in /CKEditor/plugins/codemirror/css/codemirror.min.css to

    .cke_reset_all .CodeMirror-scroll * {
    white-space: pre-wrap;

And you may also want to remove ckeditor global CSS reset to make custom fonts in CodeMirror work.
