Hmmm... I think I get... some of that... me thinks.... :) I also just
thought that "define" is possible only as part of marco
(https://tiddlywiki.com/#Pragma) and only one define per macro is possible
(the one that starts at the very beginning of tiddler), but that's not that
important.
In the end I decided to use your second option like:
\define rating()
<$vars style={{{ [{!!rating}compare:number:gteq[7]then[green]]
~[{!!rating}compare:number:gteq[5]then[grey]] ~[[red]] +[addprefix[font-size:
1.5em; font-weight: 500; color:]]" }}} >
<span style=<<style>>>{{!!rating}}</span>
</$vars>
\end
since 1 macro is better than 2 macros :) and I can put any kind of css
formatting inside the "addprefix" stuff.
But I have one more little questing, since we touched the Compare
operator... I read this compare Operator
<https://tiddlywiki.com/#compare%20Operator>, this Filter Syntax
<https://tiddlywiki.com/#Filter%20Syntax> and this ListWidget
<https://tiddlywiki.com/#ListWidget>, but I still don't get it... :)
I still have no idea *how to make compare operator work with field values
inside a list widget?*
For example I have a list filtered by some tag and I want to add condition
to show only tiddlers that have some date older than 20200701 and filter
them by that date.
So if I have a working list
<$list filter="[tag[Comedy]!sort[releasedate]]> <$link/> | </$list>
and I want to add additional filter condition. if to do it in accordance
with the above example if should be smth like:
[{!!releasedate}compare:date:gr[20200701]]
but why doesn't this thing work:
<$list filter="[tag[Comedy]] +[{!!releasedate}compare:date:gr[20200701]]
+[!sort[releasedate]]"> <$link/> | </$list> ?
I tried experimenting with brackets, but haven't managed to achieve
anything. :(
