Concatenating Data Tiddler Values

[Mohammad]

Is it possible to retrieve and concatenate values from a Data Tiddler (Dictionary)?

To explain in a bit more details consider the following code:

• Data Tiddler (myConfig) contains

Name: Lecture01

Tag: Lec01

Page: 001
Group: Course 348

• A button to create a new tiddler using data from the above data tiddler

<$button>

<$action-sendmessage $message="tm-new-tiddler" 

 title={{myConfig##Title}}  tags={{myConfig##Tag}} caption="{{myConfig##Tag}}-Course348"

 page={{myConfig##Page}} text=<<content "SlideContents">>/>

New Slide

</$button>

Note: content is a macro creates some texts to be inserted as a new tiddler text.

This code creates a caption filed for the new tiddler, its value is

caption="{{myConfig##Tag}}-Course348"

It may be the result of concatenation of other values like

caption="{{myConfig##Tag}}-{{myConfig##Group}}"

Is there any short solution to this?

Cheers

You need the wikify widget.  It's express purpose is to parse wiki text and store it's output for use elsewhere inside it.  So in this example, you would want the following

<$wikify name="caption" text="{{myConfig##Tag}}-Course348">

<$button>

<$action-sendmessage $message="tm-new-tiddler" 

 title={{myConfig##Name}}  tags={{myConfig##Tag}} caption=<<caption>>

 page={{myConfig##Page}} text=<<content "SlideContents">>/>

New Slide

</$button>

</$wikify>
