modules not found
by Hans van der Meer 08 Sep '21

08 Sep '21

Here is something I do not understand about \usemodule. My modules are in two places because I wanted development and production separated: (1) Volume/TeX/texmf/modules/ (2) Volume/TeX/texmf/modules-new/ Unexpected and suddenly loading files from the first directory does not occur any longer: modules > 'hvdm-tak' is not found But modules from modules-new load without a hitch: modules > 'hvdm-load' is loaded I have discard the caches and rebuilt them to no avail. Then trying mtxrun --locate filename does not show any location not even from the files that are loaded, just an empty line. What happens inside \usemodule to cause this? I confess being baffled. And how to convince ConTeXt to find all my modules? dr. Hans van der Meer

zint barcode module on LMTX/MacOS
by Henning Hraban Ramm 08 Sep '21

08 Sep '21

Hi again, the LMTX zint module uses libzint, while MkIV calls the zint binary. The latter works for me, the first not. On MacOS, the library is "/opt/local/lib/libzint.dylib"*. I changed that in the source and the file appears to be found. Could you add that, Hans? *) Previously, zint for MacOS was only available via HomeBrew; I don’t know where that would install libzint, probably in /usr/local/lib/ like on Linux. Yesterday a MacPorts port was added that I used; MacPorts install everything under /opt/. But then still zintlib.execute returns nothing. I wonder if this works on Windows? The API docs don’t mention an "execute" function. https://www.zint.org.uk/manual/chapter/5 Hraban

transparency stopped working in LMTX
by Henning Hraban Ramm 07 Sep '21

07 Sep '21

(Latest LMTX, yesterday’s luametatex binary) The MWE shows no transparency with LMTX, it works with MkIV: ''' \setupexternalfigures[location=default] \definetransparency[light][a=1,t=.05] \definelayer[bg][x=0mm,y=0mm] \setupbackgrounds[text][background={bg},state=start] \starttext \starttransparent[light]% \externalfigure[hacker]% \stoptransparent \setlayer[bg][ hoffset=5mm, voffset=5mm, ]{ \starttransparent[light]% \externalfigure[hacker]% \stoptransparent } \stoptext ''' The layer stuff is not "minimal", but I wanted to check if "multiply" works.

Dear List, I think I've just encountered a fragile bug. It is only reproducible with exactly the same layout as the doc below.

no looseness in LMTX?
by Henning Hraban Ramm 07 Sep '21

07 Sep '21

In my magazine and book projects, I sometimes fix pagebreaking by stretching paragraphs with \looseness=1 Unfortunately this works _in my project_ only with MkIV, i.e. \looseness has no effect with LMTX. I tried different examples (e.g. the attached file) and can’t reproduce the problem, there MkIV and LMTX always behave the same. So it must be something in my settings. What could cause the difference? I tried English and German and different settings of alignment and tolerance. Might it be font dependent? Hraban

Equation alignment
by Sylvain Hubert 07 Sep '21

07 Sep '21

Dear List, The following example of equation alignment copied from An Excursion is not reproducible under my context 2021.03.05 shipped with texlive 2021: \starttext \startformula \eqalign{ ax^2+bx+c &= 0 \cr x &= \frac{-b \pm \sqrt{b^2-4ac}}{2a} \cr } \stopformula \stoptext Both ampersands are rendered literally. Does anyone know how to properly typeset aligned equations? Thanks! Sylvain

Dear List, I'm using the chinese simsun font that has no builtin SerifBold. I'm trying to define a fakebold feature for it, but the following code does not work: \definefontfeature[fakebold][effect={width=0.3, delta=0}] \definefontfallback [sunfallback] [name:simsun] [cjkunifiedideographs] \definefontfallback [sunbffallback] [name:simsun] [cjkunifiedideographs][features=fakebold] \definefontsynonym [Serif] [modern] [fallbacks=sunfallback] \definefontsynonym [SerifBold] [modern] [fallbacks=sunbffallback] \starttext 人 foo \bf 人 bar % bar is bold, the second 人 is not \stoptext Does anyone know how to define features for fallback font? Thanks! Best, Sylvain
