Hi Eric There are some error use cases I wonder about: > > Let's say you have a tiddler called "Lesson1" with the "list" field set to: >> [[First Bit]] SecondBit FinalBit >> You'll also need to create the named tiddlers. >> > > What happens if a tiddler named in the list does not exist? >
Nothing; the tiddlers named in the list don't need to exist. > > >> Then, create a new tiddler called "Navigation" with the tag >> "$:/tags/ViewTemplate" and the following content: >> Next: <$list filter="[is[current]next[Lesson1]]"/> / Previous: <$list >> filter="[is[current]previous[Lesson1]]"/> >> > > What does the filter produce if the "Lesson1" tiddler is missing or the > list field is empty? > If the list tiddler doesn't exist then the next and previous filter operators always return an empty list. > > Now if you open a tiddler like "SecondBit" you should see at the bottom >> the controls to move to the next and previous tiddlers. >> The next and previous filter operators work by locating the currently >> selected tiddler(s) in the named list, and returning the adjacent next or >> previous tiddler from the list. >> > > What if the same tiddler title in the named list more than once... which > occurence does the filter match as the "current selected tiddler"? > Currently it would return the entries adjacent to the first instance of the current tiddler. > What does the [[Navigation]] template display if the current tiddler is > not in the list at all? > At the moment it still displays the Next: and Previous: text with no accompanying links. We need a way for the reveal widget to hide or show content depending on whether a filter evaluates to zero or more entries. When you reach the start/end of the list, does it loop around to the > end/start, or just stop? > It stops at each end of the list. > If navigation doesn't loop, when you reach the start/end, can display of > non-functional links be suppressed? > No links are displayed at the ends of the list. > Will there also be a [first[Lesson1]] and [last[Lesson1]] so a complete > "FPNL" (First/Previous/Next/Last) navigation bar can be displayed? > Good idea, there should be.
