Setting up zint on a mac with macOS Montery Version 12.3.1
by Keith McKay 31 May '22

31 May '22

Hi All I have been struggling today trying to setup and use the Barcode module zint in ConTeXt and failed. I have followed the instructions on the wiki ( https://wiki.contextgarden.net/Barcodes ) but with some changes as follows. Which maybe why I failed. 1) I downloaded Zint using Homebrew since I'm using macOS, and installed it according to the instructions. 2) Since I'm using LMTX I looked for the file libzint.dylib and found it in /opt/homebrew/Cellar/zint/2.10.0/lib . This is different from the path given on the wiki. The directory contained three files, two of which were aliases, libzint.2.10.dylib and libzint.dylib, and an exe file libzint.2.10.0.0.dylib 3) I created the path $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint and copied libzint.2.10.0.0.dylib into but replaced dylib with 'so' as suggested on the wiki instructions. So I basically added lib/luametatex/zint to texmf-osx-64/bin . 4) I ran mtxrun --generate to update the database. 5) I ran the MWE below but no barcode appeared. The console output shows: /modules > using user prefixed file 'libs-imp-zint'/ // /modules > 'zint' is loaded/ however further down the output it gives: /optional > unable to locate library 'libzint'/ // I have tried renaming libzint2.10.0.0.so to libzint.so, but still no barcode. Is their something I am missing? Tips or hints appreciated.

arm osx
by Hans Hagen 30 May '22

30 May '22

Hi, Thanks to Mojca's persistent efforts we now generate arm osx binaries on the build infrastructure, so lmtx now ships native arm bins for apples. There are also intel solaris builds now but no installers for those platforms (yet).

XML Namespaces and XML Setups
by Christoph Reller 24 May '22

24 May '22

Dear List, Consider the following MWE: \startxmlsetups xml:demo:base \xmlsetsetup{#1}{tag}{xml:demo:tag} \stopxmlsetups \xmlregisterdocumentsetup{demo}{xml:demo:base} \startxmlsetups xml:demo:tag %\doif{\xmlnamespace{#1}}{o}{NameSpaceO:} \xmlflush{#1} \stopxmlsetups \starttext \startbuffer[test] <?xml version="1.0"?> <root xmlns="NameSpaceA" xmlns:o="NameSpaceO"> <tag>text</tag> <o:tag>text</o:tag> </root> \stopbuffer \xmlprocessbuffer{demo}{test}{} \stoptext My questions: - Is there a good way to have a separate XML setup for each XML namespace? - Alternatively, one has to do the distinction within the same XML setup. In this case, how do we get the complete namespace? (In this example: "NameSpaceA" and "NameSpaceO") Thanks in advance for your help! Cheers, Christoph

lua-widow-control module error in LMTX
by Eduardo Bohoyo 14 May '22

14 May '22

Hi, I would like to know if anyone has experienced the same error with the lua-widow-control module when compiling the pdf: modules > 'lua-widow-control' is loaded open source > level 2, order 3, name '/opt/luametatex/texmf-modules/tex/context/third/lua-widow-control/t-lua-widow-control.mkxl'. resolvers > lua > unknown file 'lua-widow-control.lua' lua error > lua error on line 74 in file /opt/luametatex/texmf-modules/tex/context/third/lua-widow-control/t-lua-widow-control.mkxl The odd thing is that line 75 of the t-lua-widow-control file is empty. On the other hand, I confess that I don't know what "resolvers" means when it says it doesn't know the lua-widow-control.lua file. I don't see any mention of this file within the t-lua-widow-control module. Could it be that this module is not yet mature for lmtx, or am I missing something? I have \usemodule[lua-widow-control] in my tex document, and I haven't forgotten to do the prescribed mtxrun --generate after including the module in my third-party folder of my luametatex installation on Arch. Kind regards, Edu

Fuzzy paragraph when exporting to XML
by Aditya Mahajan 01 May '22

01 May '22

Hi, I am trying to debug a bug-report for t-vim: https://github.com/adityam/filter/issues/64 Exporting with trackers=export* gives a warning: backend > export > fuzzy paragraph: I have managed to narrow it down to the attached MWE (which does not depend on the t-vim module at all). Compiling it using $context --trackers=export\* lines gives the fuzzy paragraph warning. Any hints on how to resolve this? Thanks, Aditya

Problem with a defined colour in MetaFun
by Keith McKay 29 Apr '22

29 Apr '22

Hi, In the MWE below I define an rgb colour, myColor1, using random numbers for the r, g and b components. I then use it to fill a unitsquare the size of the page, which works as expected. In the loop that follows I then use the defined colour, myColor1, along with white and the variable r to create shades of myColor1 as in the MWE below. However, myColor1 is not recognised in the loop and seems to be replaced by black, although if I use a predefined colour, in this case BurntSienna from the crayola collection, it works as expected. I have tried a number of ways to get this to work as shown in the code but without success. I would be grateful for any suggestions.

Can you try the beta version at https://github.com/gucci-on-fleek/lua-widow-control/releases/tag/release-47… please? Hopefully this solves the issue. > Do you want the new pdf with lwc actually acting on my file?

I was able to reproduce the issue just by adding \setuplayout[grid=yes] to my "standard" test files, so I shouldn't need anything else, provided that the above beta actually fixes anything. If there are still lingering issues, then having the TeX source would likely simplify things on my end. -- Max

context module t-account in LMTX

Hi there I just tried to test the use of the t-account module, compiling with LMTX, but no avail. What is wrong?
