TW5: Concatenated TextReferences

[Tobias Beer]

Mhhh, I'll attribute it to having been away for a while

or maybe it's one of those things that just won't work.

Here's the situation and I can't wrap my head around solving it...

Assume...

• there's a variable state used to trigger visibility
  
• this tiddler has an additional field called new-title
• and I'm in the context of a macro that knows of a parameter old-title

Now, here's the issue...

I want to read the field new-title from tiddler state and assign it as the title to tiddler old-title.

<$button>
<$action-setfield $tiddler="$old-title$" title={{??WHAT-TO-DO??}}/>
rename
</$button>

What to do (again)?

Note: new-title got changed since the time the widget-tree was rendered.

Best wishes,

Hi Tobias,

you could define it like this:

\define changer(old-title)
<$set name="currentTiddler" value="$(state)$">
    <$button>
        <$action-setfield $tiddler="$old-title$" title={{!!new-title}}/>
        copy
    </$button>
</$set>
\end

Please note that it only archieves a copy functionality rather than a rename (i.e. the original tiddler will still exist)

Hi Andreas,

 

you could define it like this:

Muchas gracias.
Of course, the button goes into its own macro. ^_^

The following is probably around somewhere already...
If not, I've used the method to play with a litte macro

that allows to inline-edit tiddler titles or other fields of tiddlers:
