Introducing a param into a filter within a macro

#1

Sorry to bother you with this… I am a little dumb right now.
How do I get the name of the tiddler as a param into a filter within macro

\define indexoverview(tid:{{$:/state/listen}})
<$list filter="[<tid>get[text]splitregexp[\n]]" variable=each-line>
<$list filter="[<each-line>split[:]first[]]">

*{{!!title}}<$list filter="[<each-line>split[:]nth[2]]">: {{!!title}}</$list>
</$list>
\end
<$select tiddler="$:/state/listen">
<$list filter='[all[shadows+tiddlers]prefix[$:/list/]]'>
<option value=<<currentTiddler>>>{{{[{!!title}removeprefix[$:/list/]]}}}</option>
</$list>
</$select>
<<indexoverview >>

Are you asking for [<tiddler>get[title]] – isn’t it already that?

No I mean that […] should be in this case “$:/state/listen”…

  • This can happen to us all.

I think your question is answered, if not indirectly, in this reply of mine about different ways to pass parameters to macros Attribute assignment where the attribute is computed - #7 by TW_Tones

However if you are using define rather than procedure you may use $(varname$) or $paramname$ inside the macro, and for completeness <<__paramname__>> (From Eric)

If I understand your indexoverview macro, you want to pass in the name of a tiddler whose text field contains a tiddler title whose text field you want to access (i.e., a “double indirection”).

If this is the case, then try something like this:

\define indexoverview(tid:"$:/state/listen")
<$list filter="[<__tid__>get[text]get[text]splitregexp[\n]]" variable=each-line>
<$list filter="[<each-line>split[:]first[]]">

*{{!!title}}<$list filter="[<each-line>split[:]nth[2]]">: {{!!title}}</$list>
</$list>
\end

Notes:

  • You can’t use {{...}} to set the default value within the macro parameter list, so change that to just a quoted string with the default tiddler title.
  • In the first $list filter:
    • use <__tid__> to refer to the parameter value (i.e., “$:/state/listen”)
    • followed by get[text] to fetch the contents of “$:/state/listen” (i.e., the name of the tiddler selected in the $select list)
    • followed by ANOTHER get[text] to fetch the contents of that selected tiddler

enjoy,

Thanks to you all I made the solution below to keep the possibility to enter other tiddlernames to the macro to use it in other places without the select-widget just like <<indexoverview “dictTid”>>

\define indexoverview(tid)
<$list filter="[<__tid__>get[text]splitregexp[\n]]" variable=each-line>
<$list filter="[<each-line>split[:]first[]]">

*{{!!title}}<$list filter="[<each-line>split[:]nth[2]]">: {{!!title}}</$list>
</$list>
\end
<$select tiddler="$:/state/listen">
<$list filter='[all[shadows+tiddlers]prefix[$:/list/]]'>
<option value=<<currentTiddler>>>{{{[{!!title}removeprefix[$:/list/]]}}}</option>
</$list>
</$select>

<$macrocall $name="indexoverview" tid={{$:/state/listen}}/>
