Macro: How convert wikified macro output as a "List"

[Mohamed Amin]

Hi All,

I've a set of tiddlers represent my books/novels, and I'm using the following Macro to filter my books by their "Category" and "Language" :

\define myBooks(category lang)

<$list filter="[all[tiddlers]tag[$category$]tag[$lang$]]"/>

\end

and when I run <<myBooks Novel EN>> I got a "LIST" of my "English Novels" (which is working as expected)

Now, my problem is when I try to use that Macro output as a "LIST" in other part of my code (to identify other properties like Authers, Rating, ...)

for example, I tried the following :-

<$wikify name="wkfd" text="<<myBooks Novel EN>>" >

<$list variable="myList" filter="[enlist<wkfd>]">

<<myList>>

</$list>

</$wikify>

but both "wkfd" and "myList" variables are NOT "LIST" to iterate with. 

so, what is the correct way to use that macro output as a list?

Regards

Ok, I figured it out (Thanks BTC)

\define prepEnlisting(nlst) 

[[[[$(macO)$]]]]

\end

\define myBooks(category lang)

<$list filter="[all[tiddlers]tag[$category$]tag[$lang$]]" variable="macO">

<<prepEnlisting>>

</$list>

\end

<$wikify name="wkfd" text="<<myBooks Novel EN>>" >

<$list variable="myList" filter="[enlist<wkfd>]">

Auther of : <<myList>>  is {{{[<myList>get[auther]]}}}<br>

</$list>

</$wikify>

Any other implementation for the same functionality?

[Mohamed Amin]

Actually I used the following to keep Macro parameter "locally"

\define prepEnlisting(nlst) 

[[[[$nlst$]]]]

\end

\define myBooks(category lang)

<$list filter="[all[tiddlers]tag[$category$]tag[$lang$]]" variable="macO">

<$macrocall $name="prepEnlisting"  nlst=<<macO>> />

</$list>

\end

<$wikify name="wkfd" text="<<myBooks Novel EN>>" >

<$list variable="myList" filter="[enlist<wkfd>]">

Auther of : <<myList>>  is {{{[<myList>get[auther]]}}}<br>

</$list>

</$wikify>

Again, is there any other implementations?

OK this is just to give some pointers. I did not test your (nor my) code so maybe you had good reasons for exactly how you did it and my suggestions don't work.

\define prepEnlisting(nlst) 

[[[[$nlst$]]]]

\end

Not sure why you're using all those brackets. You can probably write it in a single row like:

\define prepEnlisting() [[$(nlst)$]]

\define myBooks(category lang)

<$list filter="[all[tiddlers]tag[$category$]tag[$lang$]]" variable="macO">

<$macrocall $name="prepEnlisting"  nlst=<<macO>> />

</$list>

\end

Put triple quotes around the filters when there's a chance some item has a quote character in its name.

\define myBooks(category lang)

<$list filter="""[all[tiddlers]tag[$category$]tag[$lang$]]""" variable="macO">

<<prepEnlisting>>

</$list>

\end

 

<$wikify name="wkfd" text="<<myBooks Novel EN>>" >

<$list variable="myList" filter="[enlist<wkfd>]">

Auther of : <<myList>>  is {{{[<myList>get[auther]]}}}<br>

</$list>

</$wikify>

So the wikifywidget is supposedly very resource demanding so it is to be avoided when possible. I'd guess it works with a setwidget:

Instead of 

<$list variable="myList" filter="[enlist<wkfd>]">

Auther of : <<myList>>  is {{{[<myList>get[auther]]}}}<br>

</$list>

you don't need a variable

<$list filter="[enlist<wkfd>]">

Auther of :<$link/> or <$view field=title/>  is {{!!auther}}<br>

</$list>

Thanks a lot Mat for your notes/pointers, I really appreciate it.

Regarding the "4 brackets"; actually I got it from this conversation , and it works OK with me, and if I used only 2 brackets, the "enlist" doesn't split the input variable.

Thanks again for your time here
