Thank you a lot Horus68 !
This is exactly what I needed!
I just changed your code with
author_sort:.28s.
Code:
{author_sort:.28s:'list_re_group($, ' & ', '.', '(.*?)(,|$)(.*)', '[[$:uppercase()]]')'}{pubdate:| (|)} {series:.20s| |}{series_index:0>2s| [|]} {title:.70:re(:,--)||}
Do you know, by any chance, if it is possible to have ALSO the template to include a choice between two options: 1) if {#properfilename} exists, use it as filename, 2) if not use code above ?
And is it possible to have the above code to pre-populate an empty {#properfilename] field ?
My view is no matter what, a template would never beat human intelligence for giving the perfect filename considering the length barrier, and a hand-edited fixed filename in {#properfilename} could be used whenever possible. I would like to pre-populate such custom field with template to keep hand-editing minimal.
