Hi Tones.
Thank you for your answers. Theses mostly solved my problem.
* for the duplication of filter code
OK with speed. It is simple to understand if code is duplicated but it is
more awkward to maintain and who knows if the identity of most code is
really intended or just a bug? I mean, from what you tell me, I don't care
about running that code twice, but I would like to write it only once.
could I do something like:
<$set name="selectRelatedTests" text="all[current]tagging[]butfirst[]">
<$count filter="<<selectRelatedTests>>"/> tests:
<$list filter="<<selectRelatedTests>>">
!!! <$link>
<$transclude>
</$list>
</$set>
This code does not work. But wouldn't it be more clear and maintenable than
the one below:
<$count filter="<<all[current]tagging[]butfirst[]>>"/> tests:
<$list filter="<<all[current]tagging[]butfirst[]>>">
!!! <$link>
<$transclude>
</$list>
Or something along that way of thinking (with my filter being written only
once even if it means more code otherwise). Also, you can see that your
proposed solution with $list was a perfect solution for me. I keep it as is.
BTW I think I discovered a bug. Actually, the tiddler to be transcluded
begins with a definition like
; tiddlywiki
: really cool stuff
With a direct inclusion like {{myTiddler}} that's OK and the definition is
printed correctly on screen. With the inclusion through $link and
$transclude, the definition is not interpreted as wiki code but shown as
raw wiki code, whereas bullets are correctly rendered, for instance.
Shouldn't I create a ticket for this?
