How to macro > var > macro ??

[Rustem]

I have these macros defined

\define colorize() color:$(_c)$

\define cn()
  <span style=<<colorize>>>
    some text
  </span>
\end

It works if I specify the color directly

<$vars _c=red><<cn>></$vars>

But how do I specify the color using a macro? This doesn't work:

<$vars _c=<<color tiddler-background>>><<cn>></$vars>

Is it possible?

Thanks.

Try with the setwidget, or perhaps wikifywidget instead. The varswidget is not as powerful and I don't think it can handle macrocalls as arguments. Not sure.

Tried with set widget, same, didn't work.

Try enclosing the macro call on quotes <$set value="<<macro>>">

Hi Rustem,

Try this:

\define colorize() color:$(_c)$;

\define cn()
<span style=<<colorize>>>
some text
</span>
\end

Specifying a color directly:

<$vars _c=red><<cn>></$vars>

Specifying a color using a macro:

<$wikify name="_c" text="<<color muted-foreground>>">
<<cn>>
</$wikify>

Best wishes

Jeremy.

The problem with using the <<color>> macro as a parameter value in the <$vars> widget is that the macro doesn't return a color value directly.  Instead, it returns transclusion widgets that, if subsequently rendered, results in a color value.  Here's the core definitions (from $:/core/macros/CSS):

\define colour(name)
<$transclude tiddler={{$:/palette}} index="$name$"><$transclude tiddler="$:/palettes/Vanilla" index="$name$"/></$transclude>
\end

\define color(name)
<<colour $name$>>
\end

To retrieve the actual color *value*, you can use the <$wikify> widget, which "captures" the rendered output from the macro and stores that in a variable, like this:

<$wikify name="_c" text=<<colour tiddler-background>>><<cn>></$wikify>

Note: in this example, "tiddler-background" produces "invisible" text, since the foreground text color is the same as the background tiddler color.  I assume that was your intention.

Let me know how it goes.

enjoy,

It works with <$wikify> widget. Thanks everyone!
