@Eric. Tahnk you! It does the trick but... not so much as I wanted. see the
output I get:
[image: unwanted-link.png]
"thème 5" is indeed the tittle of an existing tiddler.
What I am looking for is only the text "thème 5", not the link to "thème 5".
Now, I know how to use $wikify to acieve that goal with the current linking
result. But what I don't understand is why I got this linking in the first
place!
my code (same as yours):
\define itemlist2(tag:"thème", field:"theme", excluding)
<$set name="rejecting"
filter="[[$excluding$]!match[]then[$excluding$]else[$tag$]]">
tag=$tag$, field=$field$, excluding=$excluding$, rejecting=<<rejecting>>.
</$set>
\end
and my using that code (to get the picture above) in tiddler "choix des
critères du thème 5"
<$set name=beg value="choix des critères du ">
<$set name=theme2 filter="[{!!title}removeprefix<beg>]">
<$wikify name=theme3 text="<<theme2>>">
<$wikify name="theme-label" text="""<$transclude tiddler=<<theme3>>
field=theme/>""">
beg=<<beg>> theme2=<<theme2>> theme3=<<<theme3>>
theme-label=<<theme-label>><br>
<$macrocall $name=itemlist2 tag=<<theme-label>> field=criterion
excluding=<<theme3>>/>
</$wikify></$wikify>
</$set></$set>
And I get also this line:
[image: unwanted-link2.png]
(where I neither understand why theme2 is a link and theme3 is void)
