Assigning a set of tags within ```action-createtiddler``` widget

#1

Hallo everybody,
how do I assign a set of tags to ‘tags’ field of a tiddler just about to be created via action-createtiddler widget? I tried to assign it by putting a filter as right member of the = assignment symbol as in

<$button>
<action-createtiddler
...
tags={{{[[my]<fancy-filter>here[]]}}}
/>
</$button>

but the outcome of the above assignment is that ‘tags’ parameter only swallows in the first item output by the filter’s run.

I also tried with a variable, as in

<$set name="myTags" filter="[[my]<fancy-filter>here[]]">

<$button>
<action-createtiddler
...
tags=<<myTags>>
/>
</$button>

</$set>

but with no more success: as before, ‘tags’ doesn’t take the whole set of items output by the filter, only the first of them.

I will come over the topic again later, and elaborate a broader discussion and pose more general, more theoretical questions, but for the time being I need a quick hint on how to do the assignment.

Thanks and regards,
CG

A filtered transclusion only returns the first result from evaluating the filter, so you need to return a single string in title list format:

tags={{{ [<my-fancy-filter-here>format:titlelist[]join[ ]] }}}

If appropriate you can use tags={{!!tags}} to pass on the current tiddlers tags. This is a parameter in the
$action-createtiddler opening eg before its “>”

Also once you have created the tiddler you can use other action widgets ( createTiddler-title) inside the $action-createtiddler or still within the same trigger/button, such as ActionSendMessageWidget with the tm-add-tag message, an ActionListopsWidget to manipulate lists like a tag field, or ActionSetFieldWidget for single or prepared values.

There are so many ways to do it.

Just google search across here. Thanks for the hint about join[ ].

Here is my button to create new tiddler with a template

\procedure temp-tiddler() $:/state/ego-store-lite/newAction
\function temp-tiddler-draft-title() [<temp-tiddler>get[draft.title]]

    <$action-createtiddler
      $basetitle=<<temp-tiddler-draft-title>>
      $template=<<temp-tiddler>>
      tags={{{ [<temp-tiddler>get[tags]enlist-input[]] [[$:/Tags/Gamification/RealityAction]] +[join[ ]] }}}
    >
      <!-- delete temp tiddler and temp fields  -->
      <$action-deletetiddler $tiddler=<<temp-tiddler>>/>
      <$action-deletefield $tiddler=<<createTiddler-title>> draft.title draft.of/>
      <!-- go back to actions tab -->
      <$action-setfield $tiddler="$:/state/tabs/ego-store-lite/1" text="$:/plugins/linonetwo/ego-store-lite/tiddlywiki-ui/actions-list/actions-list"/>
    </$action-createtiddler>
    <<lingo Create/OK>>
  </$button>

You will need +[join[ ]] to allow adding multiple tags.
