Special formatting of a tiddler with a specific tag

[joearms]

I want to format tiddlers with a specific tag in a particular way.

I have made two tiddlers

 

   1) called mod:lists:reverse:2

With tag 'erlang_code' and content

   %% reverse a list

   reverse([], L) -> L;

   reverse([H|T], L) -> reverse(T, [H|L]).

    2) a tiddler called  test_formatting with tag $:/tags/ViewTemplate

and content

    <$list filter="[is[current]tag[erlang_code]]">

      <button>Compile</button>

      <pre>

      {{!!text}}

      </pre>

     </$list>

When I do this the text of the tiddler 1 is rendered twice

(as in the attachment)

How can I get the content to be rendered once inside the body of the $list macro?

Cheers

joe,

I don't follow the whole story here, but you should only see this twice in the tiddler that is tagged viewtemplate, any other tiddler that has the tag should only show it once.

The view templated tiddler shows its content and itself as a result of the view template. So you see it twice.

Have you tripped over yourself?

Regards

Tony

That's what I thought :-)

The enclosed file tiddler.png is the rendered version of mod:lists:reverse:2 and show the content TWICE first the content then the content processed inside

by the tiddler with the viewTemplate tag

The problem is that the custom ViewTemplate doesn't *replace* the standard view... it ADDS to it to the end of the standard view.  Thus, you see the tiddler content twice: first as standard wikitext output (the normal tiddler display) then followed by your custom-formatted output.

To get the results you want, you need to suppress the standard output... but only when the tiddler is tagged "erlang_code".

One quick way to achieve this is to use CSS to hide the standard tiddler "body" element.  Just put the following CSS into a tiddler tagged with "$:/tags/Stylesheet":

[data-tags*="erlang_code"] .tc-tiddler-body { display:none; }

That should fix your problem.  Let me know how it goes.

How do you know this? - did you read some code (which?) or is this documented someplace???

It worked -
