My apologies... I'm using MUCH more verbose in my responses. Let me try again: Using this code: <$list filter="[all[tiddlers]nsort[]]"> <$list filter="[all[current]removeprefix{!!nr}}"> ... </$list> </$list> The outer $list widget iterates over all the tiddlers in the document, sorted numerically. By default, as it iterates, it sets the value of the "currentTiddler" variable, so that within the outer $list, the "currentTiddler" is equal to each tiddler title it finds, one at a time. The inner $list widget then operates on the current tiddler title, using filter syntax "all[current]", and removes the prefix (if any), based on the value of the "nr" field of the current tiddler. Here's where I left out some explanation (and some important syntax too!)... Within the body of the inner $list widget, the value of currentTiddler should then be a tiddler title with the number prefix removed. However, there's TWO issues here that I failed to touch on: 1) If there is NO "nr" field in the current tiddler, then the "removeprefix" filter will return the current tiddler title, unchanged. This would cause matches with tiddlers that are unnumbered. To exclude those tiddlers and only show tiddlers that actually have an nr value defined, we need to test that the "nr" field is actually present in that tiddler, by using the has[fieldname] filter operator, like this: <$list filter="[all[current]has[nr]removeprefix{!!nr}}"> 2) I used "..." as a placeholder for "... and then you do more stuff with the matched tiddler..." Let's assume that "more stuff" is something like "output a link to the matched tiddler". To do this, you want to preserve access to the FULL name of the tiddler, *including* the number, so you can link to it. But you also want the truncated tiddler title *without* the number for display purposes. To do this, you can add a separate "variable" param to the <$list> widget, like this: <$list filter="[all[current]has[nr]removeprefix{!!nr}}" variable="thistiddler"> This will avoid changing the value of "currentTiddler" as set by the outer $list widget, and instead using "thisTiddler" to store the title with the prefix removed. You can then construct a suitable $link widget output within the inner $list widget, using both variables accordingly... like this: <$list filter="[all[tiddlers]nsort[]]"> <$list filter="[all[current]removeprefix{!!nr}}" variable="thisTiddler"> <li> <$link to=<<currentTiddler>>> <$text text=<<thisTiddler>>/> </$link> </li> </$list> </$list> Notes: a) The <li>...</li> syntax makes the output show as a bullet point b) The $link widget uses the value of "currentTiddler" by default, so it could be written as just <$link>...</$link> without the to="..." param and it would still work as intended c) The $text widget ensures that the text is displayed without additional processing for automatic WikiWord linking (e.g., if the tiddler title is "0123 SomeThing", then the "SomeThing" text won't become a link to a "SomeThing" tiddler, but WILL be linked to the full "0123 SomeThing" title, based on the containing $link widget. I hope this explanation doesn't confuse you more! let me know how it goes... -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
