How do I display nested transclusion within a codeblock?

[Branimir Braykov]

I have problems figuring out how to (properly) achieve the following:
I have a tiddler called "test". There are 3 fields in it:

• field a = abc
• field b = def
  But
• field c = {{!!a}}-concat-{{!!b}}

When I just test with transclude, field c as {{test!!c}} in another tiddler I see the rendered concatenated value: abc-concat-def. But if I try to put it in a codeblock widget I get this its definition: {{!!a}}-concat-{{!!b}}.

Now what I eventually want is to display the value of test!!c within a codeblock with a copy-to-clipboard button.

Not sure what you mean by "codeblock" in this context.

But if you were using the copy-to-clipboard macro, then you could wikify the text first:

<$wikify name="copyme" text={{!!c}}>
<$macrocall $name="copy-to-clipboard" src=<<copyme>>/>
</$wikify>

Yes, it seems is the wikify moment I was missing.

By codeblock I mean the CodeBlockWidget or just to have this text in <pre> tags and have the exactly as this is made in tiddlywiki.com. Examples are all in a codeblock with the option to copy it to the clipboard, the button properly aligned to the top right of the text. Minus the Try button part.
