[tw5] Idea: Filtered transclusion but as only the filter

(Somewhat related to a post I just made about “filter links”)

Here’s a syntactic idea: It would be neat if filters could be run directly instead of having to be encapsultated in arcane triple braces (arcanely called “filtered transclusion”)? I.e instead of

{{{ [tag[HelloThere]] }}}

…it could just directly be…

[tag[HelloThere]]

…and the output from the filter is shown.

AFAIK, a plain bracket link [[HelloThere]] is considered a filter, evidently run to give the link. (But [title[HelloThere]] does not work.)

G’day Mat,

Without knowing TW’s guts, I’m tempted to say that kind of notation would get TW into a bit of notation overload (i.e. a notation meaning different things depending on the scenario/context, and maybe getting a little hard to differentiate between the scenarios/contexts.)

That might be pushing successful parsing beyond limits.

But it would take somebody in the nitty-gritty-know to chime in.

Thanks for your thoughts. Yeah, I don’t expect it to be anything doable, I just figured it was a neat thought. The reason for the distinct triple braces are, I must assume, to make it unique. If single square brackets were used, I guess there’d have to be some additional condition on the content between the brackets and I’m sure this would make things more complicated.

But still, it would be pretty me thinks :wink:

Oh for sure, I agree: it is very pretty.

And subtle looking too, but then I quickly fall back into paralysis by analysis, thinking “but maybe that is too subtle”: will it grab me by the jugular to let me know clearly what’s going to happen right there, in the mist of everything above and below it?

So yeah, triple-curly brackets: ugly, but definitely quick to see what’s going on. (“Yup, there’s a transclusion.”)
