filter operators on dictionary contents

[Alex]

Hi,

Recently, I had to find dictionary tiddlers that have property validateAll: true.  The only thing I was able to come up with was the awkward snippet like below (yes, I know that prefix[true] is not the exact match for true):

<$list filter="[type[application/x-tiddler-dictionary]]" variable=xxx>
  <$list filter="[<xxx>getindex[validateAll]prefix[true]]" >
  <<xxx>>
  </$list>
  <br/>
</$list>

Is there a more elegant way of doing this, preferably purely through filter expression? It would be nice to have something like [field:##validateAll[true]], or a special operator dedicated to dictionaries...

Alex,

I don't know if this is the best way to do it, but I believe it should work until someone posts a more elegant solution.

<$list filter="[type[application/x-tiddler-dictionary]]" variable=dataTid>
    <$list filter="[<dataTid>getindex[validateAll]]">
        <$reveal type="match" text="true" stateTitle=<<dataTid>> stateIndex="validateAll">
            <<dataTid>>
        </$reveal>
    </$list>
    <br/>
</$list>

I found this issue intriguing, and remembered Thomas Elmiger's Compare if-then-else Style in Wikitext

So this should also work - meaning it finds and lists Data Tiddlers that:

• have an index named:  validateAll
• that has its data: true
• and as a bonus, it makes a link to the tiddlers

\define make-link() <$link to="$(display)$">$(display)$</$link><br>

<$list filter="[type[application/x-tiddler-dictionary]]" variable=dataTid>

<$set name="display" value=<<dataTid>>>
<$set name="data" tiddler=<<dataTid>> index="validateAll">
<$list filter="[<data>] -[[true]]" emptyMessage=<<make-link>>>
</$list>
</$set>
</$set>
</$list>

Nice ss

Make link is worth being a global macro.

Thanks for sharing
