Hi, Is there a way to have formula numbers showing all prefix segments? When I use prefixsegments, I get the desired numbering in the placelist but not in the formula number itself. For example: \starttext \setupcaption[figure][way=bytext,prefixsegments=1:*] \setupformulas[way=bytext,prefixsegments=1:*] \startsection[title=Section] \startsubsection[title=SubSection] \startplacefigure[list=cow] \externalfigure[cow] \stopplacefigure \startplaceformula[reference=eq1] \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \stopsubsection \stopsection \placelistoffigures[criterium=all] \placelist[formula][criterium=all] \stoptext The figure has number 1.1.1 and is in the list as 1.1.1, the formula has number 1.1 but is listed as 1.1.1. I would like to have the formula numbered 1.1.1 as well (as referenced in the placelist), so with section and subsection numbering. Adam

Keeping track of hyphenations
by denis.maier＠ub.unibe.ch 20 Mar '21

20 Mar '21

Hi Is there a way to conveniently track hyphenations ? I've had a look at https://wiki.contextgarden.net/Trackers but couldn't find anything. I'm thinking of something like this: add information about all hyphenated words to the log so that this could be further processed with a script maybe. All the best, Denis

Error "double-free glue_spec"
by Christoph Reller 20 Mar '21

20 Mar '21

Hi, For one of my projects ConTeXt LMTX 2021.03.17 17:46 fails with: error (nodes): attempt to double-free glue_spec node 145, ignored mtx-context | fatal error: return code: 1 Unfortunately, when I try to minimize the project, the error vanishes. I guess I have to send Hans the whole project, or are there other possibilities? Cheers, Christoph

working on page refs with MP

Hello everyone, I'm having page references and want to calc / draw 'Page x of y' for some subsections in MP.

Ligatures missing with Times New Roman
by denis.maier＠ub.unibe.ch 18 Mar '21

18 Mar '21

Hi I'm have to use Times New Roman for a text, and I'm finding that ligatures don't seem to work properly. \starttext \definedfont[name:timesnewromanpsmt*default at 12 pt] ff fl \definedfont[name:linlibertineo*default at 12 pt] ff fl \switchtobodyfont[pagella] ff fl \stoptext The ff and fl ligatures work out of the box with Linux Libertine O, and with TeX Gyre Pagella, but not with Times New Roman. I can use the ligatures in MS Word so the font has them, but I don't see why they shouldn't work with ConTeXt (LMTX). Best Denis

Math: Nested Cases?
by Weber, Matthias 18 Mar '21

18 Mar '21

Hello, Is it possible to nest cases in math, like so: \starttext \startformula x= \startcases[align={right,left},distance=3pt] \NC a \NC = \startcases[align={right,left},distance=3pt] \NC 1 \NC \text{case a1} \NR \NC 2 \NC \text{case a2} \NR \stopcases \NR \NC b \NC = \startcases[align={right,left},distance=3pt] \NC 3 \NC \text{case b3}\NR \NC 4 \NC \text{case b4}\NR \stopcases \NR \stopcases \stopformula \stoptext I get an error about a missing $ when I try a nested start/stop-cases. Thanks, Matthias
