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
