Settings for WysiwygPlugin that are common to most editor integrations

WYSIWYG_EXCLUDE - Prevent WYSIWYG editing

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.
