As reported on the dev-luatex list --- is converted to an en-dash (instead of em-dash) if there are no spaces around the ---.

We could now reproduce the problem also with the generic fontloader: it appears only with mode=node. I'm using the files from 2019-02-14, but the problem appeared first in the files from 2018-11-18):

\font\test={file:texgyreheros-regular.otf:+tlig;mode=node;}\test

dashes-these % gives dash

dashes--these % gives en-dash

dashes---these % gives en-dash WRONG

dashes --- these % gives em-dash

em-dashes---these % gives em-dash

\bye

context is not affected, there the code works fine.

This issue can be fixed in the fontloader with the attached patch. Hm, I don't see those lines here and it looks ok in context so ... no

For reproduction in context, the code \starttext ff\discretionary{l}{}{l} \stoptext currently produces a single `fl` ligature instead of `ffl`. Interesting that you didn't see those lines, maybe we have different versions? The patched line is line 844 in the file `font-ots.lua` of ConTeXt beta, updated today. Best regards Marcel

patches applied (and definitely not in the tex live code freeze window)

You need to set automatichyphenmode=0 to see the problem in context: the handling of the --- ligature is clearly broken in some cases: \starttext \automatichyphenmode=0 A---B A --- B \stoptext

Hm, I don't see those lines here

I see local tail = getprev(stop) in line 844 of font-ots.lua in a just updated context minimals. If I change this to local tail = stop as suggested by Marcel and rebuild the formats, the ligature behaves again.

TeXLive is frozen and pretest has begun, so I don't see a danger to apply patches now. -- Ulrike Fischer http://www.troubleshooting-tex.de/
