Sort Filter Run Prefix: Flag seems does not work with variables

[kookma]

1. goto https://tiddlywiki.com/prerelease/

2. create three tiddlers with below titles all tagged with xtx as below
   one: first
   two: second
   three: third

3. In another tiddler enter the below code

\define ff() :sort:$(sortType)$:$(sortNegate)$[split<delimiter>!is[blank]trim[]nth<pos>]

\define test2()

<$vars pos=2 sortType=string delimiter=":" sortNegate="reverse"> 
<$list filter="[tag[xtx]] $(ff)$ ">

</$list>
</$vars>
\end

<<test2>>

It does not work with reverse flag when the revers is sent as a variable!

But if you literally use the reverse, it works so the below code works correctly

\define ff() :sort:$(sortType)$:reverse[split<delimiter>!is[blank]trim[]nth<pos>]

\define test2()

<$vars pos=2 sortType=string delimiter=":" sortNegate="reverse"> 
<$list filter="[tag[xtx]] $(ff)$ ">

</$list>
</$vars>
\end

<<test2>>

Is this a bug in :sort:type:flag[] or something else is wrong?

Before <<test2>> add:

<$log test2=<<test2>>/>

Then check the browser developer console. I suspect you will see the issue is with the variable substitution in the nested macro.

Hi Saq

This is what I get! both position for sortType and sortNegate are empty!

To reproduce I have attached a zip of all tiddlers

The below code works, but I do not understand the reason

\define ff() [tag[xtx]] :sort:$(sortType)$:$(sortNegate)$[split<delimiter>!is[blank]trim[]nth<pos>]

\define m01() $(sortType)$:$(sortNegate)$


\define test2()
<$vars pos=2 sortType=string delimiter=":" sortNegate="reverse"> 

<$list filter=<<ff>>>

</$list>

</$vars>
\end

<$log test2=<<test2>>/>

<<test2>>

Note to <$list filter=<<ff>>> and my previous filter <$list filter="[tag[xtx]] $(ff)$ ">
