Wow thanks - more twisty passages So the definition is
\define list-links(filter,type:"ul",subtype:"li",class:"") <$type$ class="$class$"> <$list filter="$filter$"> <$subtype$> <$link to={{!!title}}> <$transclude field="caption"> <$view field="title"/> </$transclude> </$link> </$subtype$> </$list> </$type$> \end Now all I need is a line by line description of how this works - at a guess (and I have to guess since I have seen no description) the first line says that list links has three parameters called filter type subtype and class I also assume that if values are not supplied by the caller that the quoted value is used. For example if no subtype is given the value "li" is assumed. Then I assume that $var$ in the definition means substitute the value of the variable so <$type$ class="$class$"> is expanded into <ul class=""""> so far so good (I am getting warm?) Next line <$list filter="$filter$"> So this expands into <$lst filter=something> Where something came from the caller So now I need to find out what <$list ...> does I can find the documentation but where is the code for this - this is the list widget I assume. Thanks BTW I'm slowly getting there next problem find the code for <$list ,,,> and <$link ...> etc. Cheers /Joe On Saturday, 10 March 2018 13:39:32 UTC-8, Xavier wrote: > > Hi Joe, > > More knowledgeable people would express it differently, but one way to > look at these constructs is that the "result" of most widgets and macros is > to act on the wiki (render elements and respond to user interaction), so > *don't > look at them as programming functions* from which you could generally get > a result in order to save it and/or reuse it.
