WYSIWYGPLUGIN_WYSIWYGSKINmust be set for this to work. The flow of control is as follows:

%WYSIWYG_TEXT%expands to the HTML of the content-to-be-edited. This is suitable for use in a

WYSIWYGPLUGIN_WYSIWYGSKINmust be set to the name of the skin used for WYSIWYG editing. This is often the name of the editor e.g.
IFRAME. The flow of control is as follows:
XmlHttpRequest) to obtain the HTML document to be edited
viewURL with the
wysiwyg_editparameter and uses the TML2HTML? translator to prepare the text, which is then returned as
text/plainto the browser.
%OTOPIC%, can be used in the content URL in the edit template to refer to the source topic for the content.
XmlHttpRequestto perform saves, by POSTing to the Foswiki
savescript with the
wysiwyg_editparameter set to
1. This parameter tells the
beforeSaveHandlerin the WysiwygPlugin to convert the content back to TML. See CommandAndCGIScripts for details of the other parameters to the
savescript. Once the save script has completed it responds with a redirect, either to an Oops page if the save failed, or to the appropriate post-save URL (usually a
view). The editor must be ready to handle this redirect.
uploadscript normally redirects to the containing topic; a behaviour that you usually don't want in an editor! There are two ways to handle this:
XmlHttpRequest, then the 302 redirect at the end of the upload can simply be ignored.
uploadscript to suppress the redirect. In this case you will get a
OKfollowed by a message if everything went well, or an error message if it did not.
XmlHttpRequestto convert content from TML to HTML and back again. The plugin defines the following REST handlers:

.../rest/WysiwygPlugin/tml2html?topic=Web.Topic;text=tmltexttotranslateConverts the TML text to HTML.

configure, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.
This is not supported currently by the TinyMCE Editor. This setting is not used.The global preference setting
WYSIWYG_EXCLUDEcan 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.
calls- macros with parameters e.g.
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|INCLUDEYou should set
WYSIWYG_EDITABLE_CALLSin SitePreferences, or in WebPreferences for each web.
WYSIWYGPLUGIN_PROTECT_EXISTING_TAGSpreference tells the translator that certain HTML tags which were originally in the topic text should remain as HTML tags; the translator will not try to convert them to TML. The default setting for this preference is defined within the plugin. It corresponds to
div, span. This feature may be disabled by setting the preference to a single comma. Thi does not guarantee that HTML markup will be removed; the conversion of HTML tags to TML markup remains subject to the other controls provided by the WysiwygPlugin, including the
<literal>blocks and the rules applied to tables and lists.
WYSIWYGPLUGIN_STICKYBITSto 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 toThis 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
table=background,lang;tr=valignwill stop the translator from trying to convert any
tabletag that has
langattributes, and any
trtag that has a
valignattribute back to Foswiki
| table | column |markup (regardless of where that
tabletag comes from).
tag1=attrib,attrib;tag2=attrib. Attributes delimited by comma, and tags delimited by semicolon.
.*=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 = (?!IMG).*=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,typeIf 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. Implementors note if you are using your own before/after edit handlers, you can call
Foswiki::Plugins::WysiwygPlugin::isWysiwygEditable()to check these controls. WysiwygPlugin is incompatible with plugins that expand non-standard syntax e.g. Foswiki:Extensions.MathModePlugin (WysiwygPlugin) Plugins that extend the syntax using macros, such as
%MYMACRO%, should work fine. Implementors note plugins that use XML-like tags may call Foswiki::Plugins::WysiwygPlugin::addXMLTag() from their
initPluginhandlers to make WysiwygPlugin protect the content between XML-like tags, just like it does for macros. WysiwygPlugin. The most obvious case of this is to do with styles. For example, the sentence
*bold _bold-italic* italic_is legal in TML, but in HTML is represented by
<strong>bold <em>bold-italic</em></strong> <em>italic</em>which gets translated back to TML as
*bold _bold-italic_* _italic_which is correct by construction, but does not render correctly in Foswiki. This problem is unfortunately unavoidable due to the way TML works.
| ^ |markup). WysiwygPlugin will therefore only perform row-span related conversion if TablePlugin is enabled. TablePlugin is enabled by default and hence WysiwygPlugin converts tables with cells that span rows between TML and HTML by default. If TablePlugin is not enabled, then TML table cells containing only
^are not converted to rowspans, and HTML tables containing rowspans are not converted to TML.
