When I update to ConTeXt LMTX version 2021.03.20 01:07, the following happens during format generation: tex error > tex error on line 25 in file spac-hor.mkxl: Undefined control sequence <line 3.25> \bitwiseflip \normalizelinemode \flattendiscretionariescode <empty file> So, what is happening here?

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
by Pablo Rodriguez 19 Mar '21

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. How can I pass 'em down so I end up with numbers to do calculations with? \setuplayout[header=15mm] \def\myHeader[#1]#2{ \ignorespaces \getdummyparameters[ref=,next=,#1] \pagebreak[yes] \pagereference[\dummyparameter{ref}] \doassign[header][first=\dummyparameter{ref}] \doassign[header][next=\dummyparameter{next}] {\tfc\bf{#2}}\par \vskip3mm } \def\fillWithText[#1]{ \dorecurse{#1}{ \input tufte \input knuth } } \setupheadertexts[\setups{page:header}]% \startsetups page:header \setupMPvariables[hdrPgs] [curr=\pagenumber, first={\ref[page][\headerfirst]}, next={\ref[page][\headernext]}] \framed[ frame=off, background={hdrPgs} ]{}% all to be done in MP \stopsetups \defineoverlay[hdrPgs][\useMPgraphic{hdrPgs}] \startuseMPgraphic{hdrPgs} StartPage; % calc and draw 'Page x of y'.... numeric numCurr; numCurr := \MPvar{curr}; string strFirst; strFirst := "\MPvar{first}"; string strNext; strNext := "\MPvar{next}"; message("======================="); message("MP_hdrPageNrs: curr="& tostring numCurr & ", sFirst="& strFirst & ", sNext="& strNext); % fails: numeric numFirst; numFirst := \MPvar{first}; StopPage; \stopuseMPgraphic \starttext \myHeader[ref=a,next=b]{AAAA aaaa AaAaAaAa} \fillWithText[10] \myHeader[ref=b,next=c]{BBBB bbbb BbBbBbBbBb} \fillWithText[3] \myHeader[ref=c,next=d]{CCCC ccccc CcCcCcCc} \fillWithText[8] \myHeader[ref=c,next=last]{DDDD ddddd DdDdDdDdDd} \fillWithText[8] \pagebreak[yes] \pagereference[last] This is the last page, goodby \stoptext metapost > message : MP_hdrPageNrs: curr=1, sFirst=\ref [page][a], sNext=\ref [page][b] metafun > log > metafun > log > error: Improper subscript has been replaced by zero metapost > log > <*> ... numeric numFirst; numFirst := \ref [page] metafun > log > metafun > log > A bracketed subscript must have a known numeric value; So MP gets the macro and tries array access...

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
