Question

Is it possible to dynamically change the value of "custom" TWikiVariables, at the topic level ---- either by using templates, or skins, or some other means ?

Environment

Prepatory Information

I have created a pair of custom TWikiVariables in order to build a 'COMMENT' feature. The very basic feature allows users to hide a 'COMMENT' inside of a standard icon. Two variables are defined like this in TWikiPreferences:

      * Set COMMENT = <img src="%WIKIPICTURE%/comment.bmp" alt="
      * Set ENDCOMMENT = " />

They're used by surrounding the user's comment with the variables, like this:

                 %COMMENT% {comment goes here} %ENDCOMMENT% 

Description of the Problem

The problem arises when folks want to print the topic. Only the icon prints, and not the comment text. Also -- it would be nice to build a "show all comments" or "hide all comments" button (template).

For example, the "show comments" template, would have new values for these variables:

      * Set COMMENT = <i>
      * Set ENDCOMMENT = </i>

Can someone please tell me how to dynamically adjust the value of the TWikiVariables, based on web topic name, template, or skin ?

Thank you !
