Hi,
It seems that the 'sorttype' option is not recognized in '\setupbtxrendering'. I tried all the different values (page 25 in mkiv-publications.pdf) but nothing changes. The log files suggests that the option is not read correctly. I just find a way to make the 'sorttype' option work. If I first define a named rendering with '\definebtxrendering', the 'sorttype' is correctly read... Don't know why it doesn't work with the default rendering.
% test-biblio.tex \usebtxdataset[biblio.bib] \definebtxrendering[example] \setupbtxrendering[example][sorttype=index]
\startdocument \startchapter[title=First chapter] \input ward \cite[ward,knuth]\blank \placelistofpublications[example] \stopchapter \stopdocument % end
% biblio.bib @book{knuth, title = "Title", author = "Knuth", publisher = "Publisher", year = "2019", } @book{ward, title = "Title", author = "Ward", publisher = "Publisher", year = "2019", } % end
All the best. -- Romain Diss
