ConTeXt: specify a path to font in \definefontfamily
by Krešimir Cindrić 20 Nov '19

20 Nov '19

I'm *very* new to ConTeXt, so please excuse the newbie question. I'm trying to load a font from a file. The .otf files are stored in a directory named fonts/ which is in the directory of the .tex file I'm trying to compile. This code does not work, and reverts to the default font: \definefontfamily [mainface][serif] [My Font] [tf=file:./fonts/MyFont.otf, it=file:./fonts/MyFont-It.otf, bf=file:./fonts/MyFont-Bd.otf, bi=file:./fonts/MyFont-BdIt.otf] \setupbodyfont[mainface] \starttext\title{Hello, world!} Hello World! \emph{Hi!} \stoptext However, if I copy the .otf files into the same directory as the .tex file, and write tf=file:MyFont.otf etc, then everything works fine. How do I specify a relative path to the font, inside the .tex file? In LaTeX, I would use fontspec package and do the following: \setmainfont {MyFont.otf} [Path =./fonts/, ItalicFont = MyFont-It.otf] However, I couldn't find the equivalent syntax for \definefontfamily in ConTeXt. Just to mention, I am using ConTeXt version: 2019.03.21 21:39 as part of TeX Live, on Manjaro Linux. Regards, Krešimir

context command line interface documentation?
by Philipp A. 20 Nov '19

20 Nov '19

Hi, I want context to shut up, specifically the “mkiv lua stats” at the end are useless to me and make me scroll up for actual error messages, but better would be to just stop after the first error. I consulted the --help docs but found them entirely unhelpful. Also there’s no examples. As doing it wrong results in no error message or indeed any kind of effect, I was in the dark. First I consulted the --help and found: “--silent=list disable logcatgories (show list with --showlogcategories)”. What’s a “list”? comma separated? Do I need string delimiters? Whatever, executing “context --showlogcategories” tells me the log category “mkiv lua stats” exists, so: “context --silent='mkiv lua stats' doc.tex” does … nothing, the lua stats are still there mocking me. OK, let’s do what you do when there’s no documentation; dive in the code: “grep -C3 'batchmode' /usr/share/texmf-dist/scripts/context/lua/mtx-context.lua” This tells me that there’s a “errorstopmode” in luatex but no way to make the context script invoke “luatex -interaction=errorstopmode”, great. Diving deeper, “setblocked” in mtxtun.lua checks if --silent=all is specified, nice! But that affects everything EXCEPT for the “mkiv lua stats”. Therefore the two most useful ways to run context (--errorstopmode and --silent='mkiv lua stats') seem impossible unless one writes a wrapper script. Would be cool to have this fixed. And to have actually useful documentation instead of having to deep-dive into mtxrun.lua. Best, Philipp PS: I filed http://tracker.luatex.org/view.php?id=1014 and http://tracker.luatex.org/view.php?id=1015

[Widgets] Any good examples for developing JS-enabled PDFs that calculate?
by Paul Mazaitis 19 Nov '19

19 Nov '19

Hi everyone, My goal is to have a PDF that - allows users to input numeric information in various fields, - makes calculations on the data in those fields, - ...and reports that information somewhere in the PDF. It seems that the widget support could handle this, but I'm struggling to understand how the pieces go together; does anyone have an example of this use case I could puzzle over? Many thanks! -Paul

layers and \llap
by Pablo Rodriguez 19 Nov '19

19 Nov '19

Hi Hans, this comes from a previous message about an issue with \llap and layers. Here is the sample: \defineviewerlayer[print][state=stop,printable=yes] \defineviewerlayer[view][state=start,printable=no] \starttext \startviewerlayer[view]\color[red]{\TeX}\stopviewerlayer% \startviewerlayer[print]\llap{\ConTeXt}\stopviewerlayer% \input zapf \stoptext If the layer with \llap is placed last, disabling the view layer disables all the text. Everything works fine if the layer with \llap is placed first. I guess this might be a bug. Many thanks for your help, Pablo -- http://www.ousia.tk

developer not verified error
by Alan Bowen 19 Nov '19

19 Nov '19

Though I was able to download the latest ConTeXt beta without any problems, my attempt to update my ConText-LMTX installation was blocked. The error message was *“mtxrun” cannot be opened because the developer cannot be verified* macOS cannot verify that this app is free from malware. Safari downloaded this file on April 29, 2019. I am not sure why this is happening and wonder if it would OK to copy mxtrun from my ConTeXt installation and replace the version in my ConTeXt-LMTX installation with it. Alan

Re: [NTG-context] fatal error: there is no valid writable cache path

Hello, Thanks for those precisions regarding whiping the cache. For the sake of future debugging, which mtxrun option should I run to check what is the cache-path in my personal account, having a system-wide install? Regards, Damien Thiriet

fatal error: there is no valid writable cache path defined
by Damien Thiriet 16 Nov '19

16 Nov '19

Hi, I ran into trouble with caches. First I updated the new binaries and they compiled fine under OpenBSD6.6-amd64. Then I uploaded some binaries Hans asked me to test, moved this luametatex to /usr/local/context/tex/texmf-openbsd6.6-amd64/bin/, deleted files inside /usr/local/context/tex/texmf-cache (but not texmf-cache itself, since I understand whipe as cleaning inside it) and ran mtx-run --generate then context --auto. When I tried afterwards to compile those new binaries, I get this error This is LuaMetaTeX, Version 2.01.0 resolvers > caches > fatal error: there is no valid writable cache path defined Running mtx-run --generate on my user account did not solve the problem. I certainly did something wrong. I tried to revert to the standard lmtx binaries running install.sh but those errors are still here. Regards, Damien Thiriet

Cross references to column numbers
by Oliver von Criegern 16 Nov '19

16 Nov '19

Dear list members, how can I create cross references to column numbers? I have a two column layout with column numbers in the header instead of page numbers (actually, these column numbers are calculated from the page numbers). Now I want to create a cross reference that returns the column number of the target. How can I achieve this? Of course, I can get the page number with \pagereference (for the target) and \at (for the reference), but for calculating the column number (according to what I did in the header), I would also need to know whether the target is in the left or in the right column, and I can't see how I can get this information. For an example, see the question posted by me at stackexchange: https://tex.stackexchange.com/questions/502944/context-cross-references-to-… Besides, I am wondering, regarding the generally very regular and consistent naming of commands in ConTeXt, why this is not so in the case of references. For example, to refer to a page, I need \pagereference (for the target) and \at (for the reference); to refer to a line, I need \someline (for the target) and \inline (for the reference), but only if I want it to automatically add the word "line" or something else before the number, otherwise I have to use \inlinerange. It took me some time to find that out. Wouldn't it be easier to have just one command for the target and another one for the reference, and everything else, as counters and headers to be returned, text to be added etc. to be configured by options? Best regards, Oliver.
