Transclude a value of a X-tiddler-dictionary by using a variable

[arnaud MESLE]

Hello,

I'm a newbie with TW and i'm trying to find a way to transclude a value of a X-tiddler-dictionary by using a variable, but nothing works so i would like to know if it is possible from your opinion ?

For the test, i have a datatiddler "ressource" with this entry :

{

   "step1_summary": "blabla1",

}

My target is to can set "step1" in a variable and to try to find a syntax for transclude the value of the "step1_summary" item.

On an other tiddler i have done three tests but nothing displays this value...

test 1:

<$set name="var0" value="step1">

{{ressrouce##<<var0>>_summary}}

test 2:

<$set name="var1" value="{{ressource##step1_summary}}">

<<var1>>

test 3:

<$set name="var2" value="step1_summary">

{{ressource##<<var2>>}}

Any help would be appreciate !

Cheers - Arnaud

Greeting Arnaud... welcome to TiddlyWiki!...

In TW5, quotes don't just surround the parameter values; they indicate the kind of parameter and how it is to be handled.

* a literal text parameter value is enclosed in double quotes:

value="foobar"

* a reference to a tiddler field or data dictionary index is enclosed in doubled curly braces

value={{tiddlername!!fieldname}}
value={{tiddlername##indexname}}

(note: if the 'tiddlername' portion of the reference is omitted, the reference is to a field/index in the currentTiddler)

* a reference to a variable is enclosed in doubled angle brackets

value=<<variablename>>

Thus, your "test 2" was very close... just remove the double-quotes around the value parameter, like this:

<$set name="var1" value={{ressource##step1_summary}}>
   <<var1>

>
</$set>

enjoy,

-e
