I thought I found a new kind of problem, but when I was writing it I
realized that this is just another case that could be solved with
"sort:eval" actually. Just mentioning it here anyway, in case that
inspires anyone:
I have a list of tiddlers tagged "author" and a list of "wiki" tiddlers,
where each of the latter is tagged with an "author" tiddler" (kind of
like that
<http://erwanm.github.io/tw-community-search/#CommunityAuthors>). The
"wiki" tiddlers have a field "latest-modification". I would like to
display a list of "wiki" tiddlers sorted by author, but with the authors
sorted by latest modification.
Btw, another thing that I think would be nice is a simple way to display
a table with the possibility to sort by any column in any order, for
instance like many tables in wikipedia
<https://en.wikipedia.org/wiki/List_of_cities_by_population_density>.
(sorry, this might be completely unrelated, it just made me think about it)

Hi Erwan,
Yes, thank you Tobias for understanding and formalizing my idea!
Should we open an issue about that?
I think we should, but let's go one more round beforehand, perhaps.
Now I'm beginning to think that it should *not* be a filter of its own
but rather a flag (/suffix) to *any* available sort filter that
instructs it to sort by the evaluated operand, e.g.:
|
{{{[sort:eval<sortfilter>]}}}
|
In other words:
Sort the input elements by the output of evaluating the specified
operand as a filter expression.
Equivalently:
|
{{{[sortcs:eval<sortfilter>]}}}
|
etc...
Not sure if an "evaluated operand" would be relevant for other filter
operations other than sorting and whether we could / should devise a
syntax that always does evaluation, no matter what filter operator.
Best wishes,
— tb
