Hi,
You've troubleshot it pretty well yourself, and you've run into a big
difference between WikiText and the kind of programming you might be used
to. To quote the docs <https://tiddlywiki.com/#Macros>, "Macros are in fact
just parameterised variables". Things don't get evaluated everywhere we put
them; generally they get substituted, and only at particular points do they
get evaluated. It takes some adjustment to get used to.
The way I look at it, it's not so much that "{{!!dico}}" and "{{!!index}}"
are *not* wikified (evaluated) within the double square bracket. It's more
that TW *does* wikify the non-linked ones to render the tiddler.
The *text* widget is a useful way of checking whether your macro outputs
something that TiddlyWiki will wikify into the result you want.
Try
<$text text=<<spaceDemo dico:{{!!dico}} index:{{!!index}}>> />
to see what it really looks like when TiddlyWiki goes to wikify it for
rendering:
space demo for "{{!!index}}" in "{{!!dico}}" [[{{!!dico}}]] (not
[[{{!!dico}}|{{!!index}}]])
As you've noticed, a text reference like that doesn't work inside the
double square brackets of the link shorthand. If you type that out into a
tiddler, you'll get the same result as if you run the macro.
The most obvious way I can think of to get the output you expect is to
write out the link widget:
\define spaceDemo2(dico index)
space demo for "$index$" in "$dico$" <$link to=$dico$/> (not
<$link to=$index$>$dico$</$link>)
\end
Best,
Chris
