Polar pgfplots seems to be broken
by Gavin 20 Dec '20

20 Dec '20

Hello, I’m drawing solar system diagrams using the pgfplots module, but the polar library seem to be broken. It looks like it is calling something with a \begin{axis}... command. Here is the error message for a short document, included below. > tex error > tex error on line 18 in file /Users/Gavin/Documents/Computer/ConTeXt/Polar Plot Experiments/Untitled.tex: ! Undefined control sequence > > \pgfplots@environment@polaraxis@ [#1]->\begin > {axis}[#1,data cs=polar,axis type=polar] > l.18 \startpolaraxis[] > > 16 \startsection[title={Polar Plot}] > 17 \starttikzpicture % tikz code > 18 >> \startpolaraxis[] > 19 \addplot+[mark=none,domain=0:720,samples=600]{sin(4*x)}; > 20 \stoppolaraxis > 21 \stoptikzpicture > 22 \stopsection > > mtx-context | fatal error: return code: 256 I’d love a fix or an idea for a work around. I’m using ConTeXt Suite (ver: 2020.12.15 10:10 MKIV fmt: 2020.12.16), but I’ve tried it with TeX Live 2020 and the MkIV included with LMTX. Both have the same issue. Thanks!

\dodoubleemptywithset not working in LMTX
by Christoph Reller 20 Dec '20

20 Dec '20

Hi, The following MNWE uses \dodoubleemptywithset. In ConTeXt MKIV it works as expected, In ConTeXt LMTX an error results. \starttext \unexpanded\def\doMyDefs[#1][#2]{\getparameters[MD#1][#2]} \def\MyDefs{\dodoubleemptywithset\doMyDefs} \MyDefs[A,B][key=val,k=v] \MyDefs[C] \typeTEX{\MDAkey} is \MDAkey. \typeTEX{\MDBkey} is \MDBkey. \typeTEX{\MDAk} is \MDAk. \typeTEX{\MDBk} is \MDBk. \stoptext Possibly, \dodoubleemptywithset is not used anymore in LMTX, in which case it should be removed. Otherwise this could be a bug. Or maybe I use it wrongly? Cheers, Christoph

lmtx-20201218 | \usetypescriptfile | typescripts > unknown library
by Richard Mahoney 20 Dec '20

20 Dec '20

In the recent versions of LMTX I've been having trouble with finding my own typescriptfile -- type-sourceserifpro.tex (attached) This file lives in the working directory of all of the other project files, and is also here: ~/lmtx-20201218/tex/texmf-fonts/tex/context/user/type- sourceserifpro.tex This file is found and executes correctly with: lmtx-20200920 but fails with: lmtx-20201218: fonts > typescripts > unknown library 'sourceserifpro' (Latin Modern is substituted for Adobe's Source Serif Pro.) My setups haven't changed and are: \usetypescriptfile[sourceserifpro] \setupbodyfont[sourceserifpro,11pt] following what's found here: https://wiki.contextgarden.net/Use_the_fonts_you_want Does anyone have any thoughts on this?

Indic fonts with MkIV and
by Robert Zydenbos 19 Dec '20

19 Dec '20

Dear all, Recently I read about the use of Harfbuzz-enhanced LuaTeX with LaTeX for writing Arabic. Following that example, I wrote a minimal test text that worked excellently for Kannada script as well: ----- \documentclass{article} \usepackage{fontspec} \setmainfont{Kedage}[RawFeature={mode=harf;script=knda;}] \begin{document} ಇದು ಹೇಗಿದೆ? ನಾನು ಹೀಗೆ ತುಂಬ ಬರೆಯಬೇಕೆಂದು ಯೋಚಿಸುತ್ತಿದ್ದೇನೆ. \end{document} ----- I want to do this in ConTeXt too! Can anyone tell me how to translate “\setmainfont{Kedage}[RawFeature={mode=harf;script=knda;}]” into ConTeXt? This could be the key to using MkIV with Indic scripts. Robert

A link to an example of poster build with ConTeXt

Hi, it's really fun to play with ConTeXt and MetaPost / Metafun to build posters (color, fonts, alignment, scaling, randomized geometry). Thanks to the ConTeXt team to make it easy.

links in LMTX

Dear list, I have the following sample: \setuppapersize[A9] \setupinteraction[state=start] \enabledirectives[references.border] \unexpanded\def\MyURL#1% {\bgroup\goto{{\tt\hyphenatedurl{#1}}}[url(#1)]\egroup} \starttext \startitemize \dorecurse{2}{\item \MyURL{a.b\\/c.d\letterhash e}} \stopitemize \stoptext Link rectangles are right with MkIV, but they don’t honour left margin with LMTX. Could anyone confirm this? Many thanks for your help, Pablo -- http://www.ousia.tk

LMTX MetaFun SVG trouble, a portion of the SVG is cut of in the PDF
by Neven Sajko 18 Dec '20

18 Dec '20

Hello all, I am completely new to TeX, ConTeXt, MetaPost, etc. (Except for some MathJax snippets and the like.) I am using Aditya's LMTX package from AUR on Archlinux. I have some SVGs (generated by the Julia Gadfly package) that represent 2D plots of some functions, and I would like to include the SVGs in a ConTeXt document so it ends up as PDF. I started creating the document by including the SVGs using the new LMTX MetaPost SVG feature, however at this point I don't know how to proceed... This is the situation: the source SVGs look fine, but after including them in the document with the new ConTeXt feature mentioned above, the bottom-most part of the image is "cut off" (not visible). In the attached ZIP I included all relevant files (.tex, .svg, .pdf, ...), as well as PNG screenshots of the PDFs (in case the issue is PDF-viewer-specific, I'm using Chromium as the PDF viewer). I tried doing this in two different ways: using includesvgfile with the offset option, and using startMPcode with setbounds in the MetaFun code. In both cases I just get blank space instead of the cut-off content How can I fix this? Related question: is it possible to get the MetaPost code that (I think) the SVG gets translated to? I'm interested in how it looks like. Thanks, Neven
