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

lmt_followtext and cycle

Hans, I’m afraid that lmt_followtext has problems with cycle again. \starttext \startMPcode{doublefun} path p ; p := (0,0)..(3,3.5)..(9,-3.5).. (12,0)..(9,3.5)..(3,-3.5)..cycle; draw p xsized TextWidth ; draw lmt_followtext [ text = "\dorecurse{9}{Just random text · } ", path = p, autoscaleup = "max", reverse=true, ] xsized TextWidth ; \stopMPcode \stoptext Many thanks for your help, Pablo -- http://www.ousia.tk

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

Add items to list with arbitrary page number
by denis.maier＠ub.unibe.ch 18 Mar '21

18 Mar '21

Hi, I need to add an item to a list with an arbitrary page number. (The reason is that I have a multivolume book, and I want to add information about the other books to the TOC) I know about this: \writetolist[section]{}{It's a test} But how can you add an arbitrary page number ? Best, Denis

placenamedformula in placelist (MKII vs MKIV/LMTX)
by Adam Reviczky 17 Mar '21

17 Mar '21

Hi, I want to use placenamedformula to list a formula in the placelist with both the formula name and the formula number (alongside the pagenumber). The example in the wiki (https://wiki.contextgarden.net/Math/Display) and the test suite (cont-tst/doc/context/tests/mkiv/math/formulas-003.tex) shows what I would like to have. Using MKII I get the desired output (1 formulaname ... and 3b formulaname ...) but with MKIV and LMTX I only get the reference from the placeformula (as 1 and correctly not listed in the placelist) and none of the placenamedformula numbers. The placeformula number is then carried onto the second placenamedformula as 1 (resulting in formulaname ... and 1 formulaname ...). I have attached the test suite file output with both MKII and MKIV. Is there a way to get the MKII output with MKIV/LMTX somehow? Adam

add more blank space when using \starteffect[hidden]
by Jeong Dal 17 Mar '21

17 Mar '21

Hi, Sometimes, I need to hide the solution of a problem. So I use \doifmode{} and \starteffect[hidden] as in the following sample file. Since I want to set more blank space if it is hidden, I add \blank[5cm] when it is in the \enablemode[hideSolution]. It works well except the figures and bars are not hidden. Only texts, even in the mp part, are hidden. It is OK for me. However, it would be much better to set the height of blank space depends on the height of hidden texts. Is there a way to set the variable height using “overlay” stuff instead of \blank[5cm]? Thank for reading. Best regards, Dalyoung \startbuffer[circles] draw fullcircle scaled 1cm; draw fullcircle scaled 1cm shifted (2cm,0); dotlabel.top(“O”,origin); \stopbuffer \def\StartHide{\doifmode{hideSolution}{\starteffect[hidden]}} \def\StopHide{\doifmode{hideSolution}{\stopeffect\blank[5cm]}} %\enablemode[hideSolution] \starttext \framed[]{This is what I want:} \framedtext[]{ \StartHide \samplefile{knuth} Overbar is not \overbar{hidden}. {\processMPbuffer[circles]} \StopHide } \stoptext
