TinyMCEPlugin

Integration of the Tiny MCE WYSIWYG Editor

This is an integration of the fast and highly functional TinyMCE WYSIWYG editor. It supports a wide range of browsers, including Firefox, IE, Safari, Opera and Google Chrome (see compatibility chart). At the time of writing it doesn't work with Konqueror.

The integration uses the Foswiki:Extensions.WysiwygPlugin to translate text to and from a format that TinyMCE can edit.

This plugin is able to swap out standard text areas and replace them with WYSIWYG editors. This means you get WYSIWYG editors for textareas in forms, as well as for the main text of the topic. It can also co-exist alongside other WYSIWYG editors.

The editor automatically "switches itself off" (i.e. reverts to the old text-only window) when editing topics that contain Foswiki content it can't handle, such as complex macros.

Editor Notes

The editor uses a translator module to convert from Foswiki Topic Markup Language (TML) to HTML and back. The translator converts special macros - such as %MACROS% - to plain text, and encloses them within HTML spans using a special style called WYSIWYG_PROTECTED. In this way the editor can detect text that is not meant to be HTML formatted. This style is also used to protect special text you enter into the editor from being interpreted when the topic is translated back into TML. If you want to add any special features that are sensitive to formatting, such as Set statements, then you should format those regions using 'Protect on save' or 'Protect forever'.

Installation Instructions

NOTES:

  • This plugin comes pre-installed on Foswiki. You should only need to re-install if there is an upgrade to the plugin.
  • It requires the very latest revision of WysiwygPlugin.
  • When installed, it replaces the old "textarea" editor. You may still access the plaintext editor with the "Wiki Text" button provided in the toolbar, however this does not necessarily give you the original raw topic content. To bypass the TML to HTML conversion process entirely, use the Raw Edit link provided by the default Foswiki skin at the bottom of the page.

First follow the installation instructions to install the Plugin:

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.

wordcount - Display the number of words down in the right corner of the editor.  
xhtmlxtras cite, ins, del, abbr, acronym Adds support for some XHTML elements, including cite, ins, del, abbr, and acronym. Generally, XHTML markup in topics is not desirable. Foswiki plugins exist to provide similar functions with more friendly TML markup

Frequently Asked Questions

The topic TinyMCEFrequentlyAskedQuestions contains more help with things like: "How do I configure the buttons in my skin?", "How do I disable the WYSIWYG?" etc.


WysiwygPlugin Settings

TinyMCEPlugin depends on WysiwygPlugin to do the conversions from HTML to TML (Topic Markup Language) and back again. For more information, see WysiwygPlugin.

WYSIWYG_EXCLUDE - Prevent WYSIWYG editing

ALERT! This is not supported currently by the TinyMCE Editor. This setting is not used.

The global preference setting WYSIWYG_EXCLUDE can be set to make the plugin sensitive to what is in a topic, before allowing it to be edited. You can set it up to veto an edit if the topic contains:

  • html - HTML tags (e.g. <div>, not including <br>), or
  • macros - simple macros (e.g. %VAR%) or
  • calls - macros with parameters e.g. %MACRO{...}%
  • pre blocks (<pre>)
  • HTML comments (<!-- ... -->)
If the plugin detects an excluded construct in the topic, it will refuse to allow the edit and will redirect to the default editor.
WYSIWYG_EDITABLE_CALLS - Exceptions to WYSIWYG_EXCLUDE
If you excluded calls in WYSIWYG_EXCLUDE, you can still define a subset of macros that do not block edits. this is done in the global preference setting WYSIWYG_EDITABLE_CALLS, which should be a list of macro names separated by vertical bars, with no spaces, e.g: * Set WYSIWYG_EDITABLE_CALLS = COMMENT|CALENDAR|INCLUDE

You should set WYSIWYG_EXCLUDE and WYSIWYG_EDITABLE_CALLS in SitePreferences, or in WebPreferences for each web.

WYSIWYGPLUGIN_STICKYBITS - Protext tags based upon their arguments

You can define the global preference WYSIWYGPLUGIN_STICKYBITS to stop the plugin from ever trying to convert specific HTML tags into TML when certain specific attributes are present on the tag. This is most useful when you have styling or alignment information in tags that must be preserved.

This preference setting is used to tell the translator which attributes, when present on a tag, make it "stick" i.e. block conversion back to TML.

For example, setting it to table=background,lang;tr=valign will stop the translator from trying to convert any table tag that has background or lang attributes, and any tr tag that has a valign attribute back to Foswiki | table | column | markup.

This setting is used only after the page has been processed by the editor. If the editor does not support a particular tag or attribute and the editor corrupts the tag, this setting will not be helpful. It is only used to prevent an HTML tag from being converted back to TML.

Format of the setting is tag1=attrib,attrib;tag2=attrib. Attributes delimited by comma, and tags delimited by semicolon.

  • The left side of the equal sign is the tag.
  • The right side of the equal sign is a comma delimited list of attributes to be matched.
If a matching tag is found, that matches any of the attributes listed, the tag will not be converted back to TML. You can use perl regular expressions to match tag and attribute names, so .*=id,on.* will ensure that any tag with an id or on* event handler is kept as HTML.

The default setting for this preference are hard coded in the plugin. If you wish to change the settings, the following list is the default setting coded in the plugin:

   * Set WYSIWYGPLUGIN_STICKYBITS = .*=id,lang,title,dir,on.*;
    A=accesskey,coords,shape,target;
    BDO=dir;
    BR=clear;
    COL=char,charoff,span,valign,width;
    COLGROUP=align,char,charoff,span,valign,width;
    DIR=compact;
    DIV=align,style;
    DL=compact;
    FONT=size,face;
    H[0-9]=align;
    HR=align,noshade,size,width;
    LEGEND=accesskey,align;
    LI=value;
    OL=compact,start,type;
    P=align;
    PARAM=name,type,value,valuetype;
    PRE=width;
    Q=cite;
    TABLE=align,bgcolor,frame,rules,summary,width;
    TBODY=align,char,charoff,valign;
    TD=abbr,align,axis,bgcolor,char,charoff,headers,height,nowrap,rowspan,scope,valign,width;
    TFOOT=align,char,charoff,valign;
    TH=abbr,align,axis,bgcolor,char,charoff,height,nowrap,rowspan,scope,valign,width,headers;
    THEAD=align,char,charoff,valign;
    TR=bgcolor,char,charoff,valign;
    UL=compact,type

If you edit using the plain-text editor, you can use the <sticky>..</sticky> tags to delimit HTML (or TML) that you do not want to be WYSIWYG edited.


Known Issues

  • Applying formats such as Headings, Verbatim, Normal, etc:
    • In Safari 4 and Google Chrome 3, selecting a format works but then the cursor is lost; subsequent changes require the user to first click the region to be formatted before each change.
    • In some versions of Microsoft Internet Explorer 6, applying formats does not work:
      • 6.0.2900.5512: Known to work.
      • 6.0.2900.2180: Known to have problems.
  • "Normal" format depends on WysiwygPlugin flattening <div> tags

Check regularly at Foswiki:Extensions.TinyMCEPlugin for updates.
