I found the next and previous filter function and did not understand them
at first.
Looking at the code it seems it's expenting as the operand a name of a
tiddler which has to have a list field which defines a "story". It is then
selecting for every tiddler in the current set of tiddlers that tiddler
which follows in the story list.
So for this to work, one needs to manually create a story list, which might
be useful in some cases.
But what I *thought *"next" and "previous" would do is: They select for the
current tiddler the one which follows in the current set of tiddlers.
Let me give you an example:
On tw5magick.tiddlyspot.com I once showed how to create a simple quiz. Now
it would be nice to be able to link from every question to the next anf to
the previous question. With the current set of features it does not seem to
be possible to do this automatically, but it would be possible with my
understanding of "next" and "previous". So what I did now is to enhance
both functions.
With this code it is now possible to create my linkage (code indented for
readability):
<$list filter="[is[current]tag[Quiz]]">
<hr>
<$list filter="[tag[Quiz]previous[]]">
Back to <$link>
<$view field="title"/>
</$link>
<br>
</$list>
<$list filter="[tag[Quiz]next[]]">
Next <$link>
<$view field="title"/>
</$link>
</$list>
</$list>
As you can see, I create the current set of tiddlers with tag[Quiz] and
filter then for the next or previous tidler with next[] and previous[].
The functionality of "next" and "previous" remains unchanged when there is
an operand.
Especially @Jeremy: Do you think this is useful?
