Why do we install context in $HOME/bin?
by juh 10 Sep '21

10 Sep '21

Dear all, the installation documentation on the wiki says: mkdir $HOME/bin/context cd $HOME/bin/context wget http://lmtx.pragma-ade.nl/install-lmtx/context-linux-64.zip unzip context-linux-64.zip sh install.sh AFAIR we had $HOME/context before. Is this intended? Is it because $HOME/bin is often in $PATH by default? What is the advantage to do it like this? juh -- Autoren-Homepage: ......... http://literatur.hasecke.com Satiren & Essays: ......... http://www.sudelbuch.de Privater Blog: ............ http://www.hasecke.eu Netzliteratur-Projekt: .... http://www.generationenprojekt.de

(neo)vim support & Lua
by Saša Janiška 09 Sep '21

09 Sep '21

Hello, some months ago there was a 0.5 release (https://neovim.io/news/2021/07) of Neovim which brings support for Lua language to a new level - "Lua as a first-class scripting and configuration language". Moreover, Neovim now it also has built-in LSP client...so, I wonder if there is some work planned to improve Vim support for ConTeXt by taking advantage of those new development related to Neovim? Sincerely, Gour -- Just try to learn the truth by approaching a spiritual master. Inquire from him submissively and render service unto him. The self-realized souls can impart knowledge unto you because they have seen the truth.

io.loaddata() or buffer.assigns()
by Thierry Horsin 08 Sep '21

08 Sep '21

Hi everybody Are there any type of files that is required by io.loaddata or/and buffers.assign ? The following code works pretty well if there is no compilation problem by g++. But it fails, i.e. \typebuffer[Mybuffer], does not produce anything if g++ fails (due to some errors in the cpp) I have checked that err.cpp is well and truly created when g++ fails. \startluacode io.savedata("complx.h",buffers.getcontent("MyBuffer1")) io.savedata("complx.cpp",buffers.getcontent("MyBuffer2")) io.savedata("testcomplx.cpp",buffers.getcontent("MyBuffer3")) local l=os.execute("g++ -O3 -Wall -o testcomplx testcomplx.cpp complx.cpp 2> err.cpp") if l==0 then os.execute("./testcomplx > testcomplx.tmp") buffers.assign("MyBuffer",io.loaddata("testcomplx.tmp")) else buffers.assign("Mybuffer",io.open("err.cpp","r")) end \stopluacode Many thanks Thierry

Did you check with --luatex (i.e. MkIV)? What’s your ConTeXt version? You left out this essential piece of information. Hraban

Dear list, Let's say we have two types of synonyms: \definesynonyms[Abrev][Abrevs][\AbrevExp][\AbrevComp] \definesynonyms[Rubrica][Rubricas][\RubricaExp][\RubricaComp] Is it possible to combine them in a unique list of merged Abrevs and Rubricas?

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.

error: (nodes): fuzzy token cleanup in whatsit node

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