Color text based on a field

[sin...@gmail.com]

Hello, 

I am trying to do something I thought would be easy, but it turned out not to be: I want to color text on a tiddler with a color stored in a field. The naive solution would look like: (color_field has the value "blue")

@@color:{{!!color_field}};

bla

@@

But that does not work. Is it possible to do what I want?

Thanks!

While it seems like a reasonable usage, this is another instance where you can't directly combine different kinds of wiki syntax.  In the above example, the TWCore parser would first have to replace {{!!color_field}} with it's value (e.g., "blue"), and then perform a second parsing action to process the resulting @@color:blue; bla @@ syntax.

Fortunately, there is a way to achieve the results you want, by using an HTML <span> instead of "@@", where the span has a style attribute that is constructed using "filtered transclusion", like this:

<span style={{{ [[color:]addsuffix{!!color_field}] }}}>

bla

</span>

enjoy,
