by Jan U. Hasecke 19 Oct '20

19 Oct '20

Hi, as I'll need to make some business charts in the near future I had a look into metafun xl. Here is the first example: \startMPcode draw lmt_chart_circle [ samples = { { 1, 4, 3, 2, 5, 7, 6 } }, percentage = true, trace = true, ] ; \stopMPcode How can I change the colors used for the sample? juh

Is synctex broken in lmtx ?
by Otared Kavian 19 Oct '20

19 Oct '20

Hi Hans, It seems that \setupsynctex[state=start] does not have any effect in LMTX version 2020.09.20 23:02, while it works fine with mkiv version 2020.06.25 10:55. Best regards: Otared

Modules installation in a ConTeXt LMTX distribution
by Tommaso Gordini 18 Oct '20

18 Oct '20

Hello everybody, on my computers (a MacBook Pro with macOS 10.13.6 and a Mac mini with macOS 10.15) I have installed a ConTeXt Standalone distribution and a ConTeXt LMTX distribution. However, while following the directions contained here https://wiki.contextgarden.net/Modules#ConTeXt_LMTX the procedure to install the modules in the LMTX is not successful. Are the indications correct? Do any of you want to write them here? Thank you very much! Tommaso

Join Foundation to Support ConTeXt for the next 50 Years
by Suminda Sirinath Salpitikorala Dharmasena 18 Oct '20

18 Oct '20

Hello, In order to keep ConTeXt maintained for the very long term future, I am wondering if there a possibility to join a foundation like the Apache Software Foundation, Linux Foundation, etc. Also perhaps more to a more liberal license so there can be commercial use of ConTeXt with some of it trickling to as code contributions, wider usage which may further translate to support and consultancy work for those familiar with ConTeXt. If commercial system uses ConTeXt as part of their system there is a chance that is it is in their best interest to maintain it also long as these systems are in operation. Also perhaps it might be best than just depend on TeX maybe fork TeX and improve it in a ConTeXt dependent way. This way ConTeXt more feature-rich and easier to maintain than carrying the technical burden of TeX. There are system like SILE typesetter (https://sile-typesetter.org/) which are developed from the ground up and also The Tectonic Typesetting System ( https://tectonic-typesetting.github.io/en-US/) This is just some ideas which I thought might be worthwhile considering.

help with filename containing spaces
by Pablo Rodriguez 17 Oct '20

17 Oct '20

Dear list, I have this sample: \setupinteraction[state=start] \starttext \def\cB{file.pdf} \def\cC{file with spaces.pdf} %~ \def\PathName{\cldcontext{[[\env{completepath}]]}} \def\PathName{% \cldcontext{string.gsub([[\env{completepath}]], "\\\\", "/")}} no spaces: \doifelsefileexists{\PathName\cB}{yes}{no} \attachment[file={\PathName\cB}]\\ with spaces: \doifelsefileexists{\PathName\cC}{yes}{no} \attachment[file={\PathName\cC}] \stoptext It works fine in Linux with spaces in file names. I invoke it with: context --purgeall --arguments="pathname={~/}" ~/a But in Windows, the actual invocation involves a loop in a batch file. Without the loop, it would read (for drag and drop): context --purgeall --arguments="completepath=%~dp1" file-above.tex I don’t get the attachment only with the file that has spaces in its name (the file is also reported as not existing). The file without spaces in the its name is being attached and reported as existing. Does anyone know what might be preventing ConTeXt in Windows not to recognize the existing file with spaces in its name? Many thanks for your help, Pablo -- http://www.ousia.tk

content of xml node (element) in lua
by Jano Kula 17 Oct '20

17 Oct '20

Hello! Processing XML I want to manipulate content of XML elements inside Lua. I can define the Lua function xml.functions.name(t), where processing happens, and use the command \xmlfunction{#1}{name} to pass the current node #1 from ctx to lua as described in the xml-mkiv.pdf manual. To access the element content xml.text(t,"/element") Lua function is used. However, using the same function xml.text("#1",/element) directly inside Lua doesn't work for me. Node #1 is available, but not the content of /element. \startluacode local node = "#1" local content = xml.text("#1","/color") context.par() context("node: ") context(node) context.par() context("lua: ") context(content) \stopluacode MWE (mkiv, beta) attached. I haven't found an example, so is it even possible? If so, which way is more efficient? Thanks, Jano

Thanks everyone
by Denis Maier 16 Oct '20

Hi, I've just published the first issue of a journal where the PDFs are produced directly from JATS XML with ConTeXt. That wouldn't have been possible without the help form you all. Thank you! Denis P.S.: I'l see if I can add some of the things I've learned to the wiki...

A Spanish introduction to ConTeXt Mark IV
by Joaquín Ataz López 16 Oct '20

16 Oct '20

Sorry. By mistake I sent the message as a reply to another one, when in fact I was trying to start a new thread with it. I'm sending it again (I think I'll do it right now): --------------------------------------------- Good morning to everyone. Although I guess it will not be of interest to most of the list members, I wanted to communicate that I have written an introduction to ConTeXt Mark IV in Spanish, which can be downloaded at https://webs.um.es/jal/docs/introCTX.pdf. Its title is "An Introduction (not too short) to ConTeXt Mark IV". ConTeXt is a wonderful document composition system, but there is not much literature to help you get into it, hence my initiative. The problem is that I've only been using ConTeXt for a short time and still have many doubts, so it's possible that the introduction may contain errors. As it has been written in Spanish I don't think many of you will be able to read it, but I would appreciate, of course, any suggestions for improvement. The document is, on the other hand, free and anyone who wants to include it in any ConTeXt distribution can, of course, do so. Also, if anyone wants the source files, I have no problem providing them. I have not based my introduction on LMTX because I think that for beginners a more stable system, like LuaTeX, is preferable. Finally, I apologize for my bad English level. I read it reasonably well, but expressing myself in it is much harder for me. -- Joaquín Ataz López Derecho Civil Universidad de Murcia

expansion / hz
by Hans Hagen 15 Oct '20

15 Oct '20

Hi, Because I'll probably forget to mention if, here is some new features (upcoming lmtx only): \definefontfeature[default][default,quality] \setupbodyfont[pagella] \starttext {whatever we want to achieve} \input tufte \setupalign[tolerant,stretch,hz] {whatever we want to achieve} \input tufte {\noexpansion whatever we want to achieve} \input tufte \stoptext That is: one can mark text to *not* use font expansion in an otherwise expansion (hz) context. I have no clue how useful it is. So, the first paragraph has no expansion., the second one has while the third one has except for the first 5 words. And yes, there's also similar trickery for protrusion, \noprotrusion, but i didn't test it. This is in addition the the already mentioned \nokerning and \noligaturing features that also obey grouping. All this in the perspective of (luameta)tex giving detailed control over matters.
