Creating a new tiddler with multiple tags from a button

[Christian Macedo]

I'm attempting to create a new tiddler with the button below:

<$button class=<<tv-config-toolbar-class>> tooltip="New Journal Entry">{{$:/core/images/file}}

<$action-sendmessage $message="tm-new-tiddler" tags=" [[JournalEntry]] <<now 0DD.0MM.YYYY>> " />

</$button> 

The first tag is created without any incident. However, the second tag doesn't It gets passed as a literal string, pehaps obviously, ending up with the unwanted tags:

• "<< now" and
• "0DD.0MM.YYYY>>"

How can I pass todays date in the format <<now 0DD.0MM.YYY>>?

Hi Christian,

maybe something like the following does the trick?

\define actions()
<$action-sendmessage $message="tm-new-tiddler" tags=" [[JournalEntry]] [[$(currentDateTime)$]] " />
\end

<$button class=<<tv-config-toolbar-class>> tooltip="New Journal Entry">{{$:/core/images/file}}

<$set name="currentDateTime" value=<<now "0DD. 0MM. YYYY">>>
<<actions>>
</$set>
</$button>

That did it! 

Thank you so much. And now I have a nice example of how to properly use set for a button which I'll need a lot. 

Thanks again!

This is a valuable lesson in the fact you should not expect the contents of a parameter to be evaluated in the same step as calling a widget. There are a few parameters that do by design such as text= in the wikify widget but these are the exception.

Use set or macro defines outside the widget to prepare the parameter for your widgets.

I wish someone told me this when I was first learning.
