Sort Text List without Writing It into a Field?

[Scott Simmons (Secret-HQ)]

Is there a good TiddlyWay to sort a text string without having to write it to a field?

I'm imagining a macro that could take an input of numbers and render a list.  E.g.,,

The account numbers are <ol><<sortEm "149 54 9 21">></ol>

... renders as:

The account numbers are 

1. 9

2. 21

3. 54

4. 149

<$list filter="149 54 9 21 +[nsort[]]">

</$list>

This works because the default handling of a filter is to treat it as a tiddler title.  tiddler titles in filters don't have to correspond to existing tiddlers.  So the list filter is being passed a list of tiddlers.  Then the "+[" sytax means, run the following filter run using the previous tiddlers as input.  So now we run nsort against them, getting back a list of tiddlers in numeric sorted order.  From there, you can format them however you like.

\define sortEm(string)

<$list filter="$string$ +[nsort[]]">

</$list>

\end

:D  AMAZING!

Thanks, Matt!  It would have been deep into the 2020s before that ever occurred to me, and it's just the quick and dirty solution I needed
