SID-01442: WysiwygPlugin "non-standard" syntax

Status:	Answered	TWiki version:	5.1.1	Perl version:	5.01
Category:	WysiwygPlugin	Server OS:	Debian 6.0.4	Last update:	13 years ago

Hello, I'm a maths student. 99.9% of my TWiki deals with maths (and its symbols)! I successfully installed a TinyMCE plugin, a formula Editor and a Java CAS.

The formula Editor and the Java CAS creates images (stored in a cache) and add this html code to TinyMCE: <img class="Editorformula" title="Double click to edit" src="/pub/TWiki/TinyMCEPlugin/tinymce/jscripts/tiny_mce/plugins/tiny_mce_Editorfomula/integration/showimage.php?formula=c3896dfef00bff09d89dbf62f9d3680e.png" alt="3 by 2" align="middle" />

What's the problem? If I "Save" the topic or click on "Edit TWiki markup" , class="Editorformula" is deleted by WysiwygPlugin.

I've just learned why: "WysiwygPlugin is incompatible with plugins that expand non-standard syntax". And maybe the class="" isn't a standard syntax.

class="" has not to be deleted. How can I do?

Please help me; TWiki is like a notebook for me and my friend-colleagues and I don't like to abandon it. Thank you very much

Discussion and Answer

There are issues with the WYSIWYG editor as you discovered

Two options for workaround:

1. Enclose the <img /> tag in sticky tags, e.g. <sticky> <img /> </sticky>. The WYSIWYG editor will leave the stuff inside sticky alone.

2. Disable the WYSIWYG editor on a page level, web level or site level with a Set EDITMETHOD = raw setting.

Hi Peter, I'm honored to speak with the TWiki's Inventor.

1. If I enclose the <img /> tag in sticky tags (in RAW Edit), the image is NO longer visible in tinymce. The image has to be visible with class attribute in its tag.

2. As before, the image has to be visible; Why? Because we would like to see all image-steps of our problems in order to edit them.

What about WYSIWYGPLUGIN_STICKYBITS? I insert "Set WYSIWYGPLUGIN_STICKYBITS = IMG=class;" in WebPreferences of my Main Web; but class attributes of img tags in Main Web's topic is still deleted by the editor (Save or Edit Twiki markup).

Thank you very much

Not sure why the following does not work:

• Set WYSIWYGPLUGIN_STICKYBITS = IMG=class

Time to debug. More at TWikiDebugging.

Plugin details at WysiwygPlugin and TinyMCEPlugin.

I forgot to say that it's the same for TinyMCEPlugin (no errors). Thanks
