Filter Module with Openscad
by Jeroen 26 Apr '23

26 Apr '23

I am using OpenSCAD to create drawings with the filter module with the following MWE: \usemodule[filter] \defineexternalfilter[openscad] [filtercommand={/context/openscad/openscad -o \externalfilteroutputfile}, output={\externalfilterbasefile.png}, cache=force, readcommand=\ReadImage] \define[1]\ReadImage{\externalfigure[#1]} \starttext \startopenscad square(4,2); \stopopenscad \stoptext This works fine. I now want to use the following options added to the command line: --view axes,edges,scales --viewall When I create an Openscad file test.scad, I can run it fine with the following command line at a CLI window: openscad.com test.scad -o test.png --view axes,edges,scales --viewall When I add this to the filtercommand as following [filtercommand={/context/openscad/openscad -o \externalfilteroutputfile --view axes,edges,scales --viewall} I cannot get it to run. Is there anything I am missing? Thanks Jeroen

Numbered Itemlist With Interruption
by Michael Urban 26 Apr '23

26 Apr '23

I am trying to have two numbered itemizations, with a paragraph in between, such that the second list starts where the first left off, without having to manually calculate the new start point. The following does not work, and I do not understand why. Mike \starttext \definecounter[mynumber][] \startitemize[n] \item The first item. \item The second item \item Item number \currentitemnumber{}, the last one. \setcounter[mynumber][\currentitemnumber] \stopitemize The \type{\getnumber[mynumber]} value is \getnumber[mynumber]. \incrementcounter[mynumber] And now the big finish, start at \getnumber[mynumber]: \startitemize[n][start=\getnumber[mynumber]] % WHY DOES THIS FAIL? \item Picking up where we left off. \item And all is well. \stopitemize Done! \stoptext

Idea for a shared repository.
by Pawel Urbanski 25 Apr '23

25 Apr '23

Dear Everyone, We currently have the Context Garden site, wiki and htis list for documentation and resources. There is a Github contextgarden organization that can host repositories. What about creating a repository called: 'templates' or 'resources' - we can figure out the exact name later. The idea behind it is to collect templates and examples that are scattered all over the web or in the list threads. The first example that comes to my mind is the type definition for a Roboto font I needed and other type scripts that can be useful for the community. Then there are templates for books, slides or documents. The Repository has a wiki where we could add some notes about more complex items. It is not about duplicating the Context garden site but to collect code in a place where we could gradually fix possible errors or introduce improvements. All the best, Pawel

fallbacks
by Thomas A. Schmitz 25 Apr '23

25 Apr '23

Hi all, today, I was struggling with a fallback font I had defined, and I discovered that the key "check" doesn't work as I expected. Here's a small example: \definefallbackfamily [presentation] [serif] [TeXGyreTermes] [range=0x2329-0x232A,check=yes] \definefontfamily [presentation] [serif] [AntykwaTorunska] \setupbodyfont [presentation,12pt] \starttext (〈P〉) \stoptext With this input, the two characters 〈 and 〉 are not typeset; in the log, I find fonts > checking > char 〈 (U+02329) in font 'AntykwaTorunska-Regular' with id 1: missing fonts > checking > char 〉 (U+0232A) in font 'AntykwaTorunska-Regular' with id 1: missing If I have "check=no," the characters are taken from termes and replaced. I was under the impression that "check" should, well, check if the characters are not in the main font and fall back to the fallback font if they are not, but this doesn't appear to be the case. So what does "check" do? Or is this a bug? Have a great weekend Thomas

adjustment to my local footnotes problem
by jbf 24 Apr '23

24 Apr '23

I realise that I should have been talking about the space between local footnotes, rather than interlinespace (previous email on this issue), but my basic problem still stands. My efforts to influence the space between footnotes placed locally is to no avail so far. I assume it is \setupnote (rather than \setupnotation, my earlier mistake) where I would need to somehow influence distance between footnotes which is currently too large. I have tried \setupnote[before={\blank[small]}, after={\blank[small]}]. It appears to be reducing the space before the entire block of local footnotes but not between the footnotes themselves, which is what I am trying to do. Am I correct in assuming that the \setupnote should influence my \placelocalfootnotes? Or is there something else I should do in the case of local footnotes as distinct from general footnotes (my document contains ONLY local footnotes, however). It seems a simple enough issue, but I just can't get it right. Julian

current Unicode blocks
by Henning Hraban Ramm 23 Apr '23

23 Apr '23

This is probably for Hans: The list of Unicode blocks in char-ini.lua is not complete, compared with ftp://www.unicode.org/Public/UNIDATA/Blocks.txt (I was looking for Kaktovik numerals, of course ;)) I’d offer to make an updated list, but maybe you already have a script for that? Hraban

interlines space for local footnotes
by jbf 23 Apr '23

23 Apr '23

I am using only local footnotes in a document, but am having difficulty influencing the interlines space between these notes. Since I am only using local footnotes, I thought initially that the following would work for them \startsetups[footnote:interlinespace] \setupinterlinespace[line=2.4ex] \stopsetups \setupnote[footnote][setups=footnote:interlinespace] but it doesn't. I had hoped there might be something like \setuplocalfootnotes but there is not. I also tried placing the setups locally, either with \startlocalfootnotes[setups=footnote:interlinespace] or \placelocalfootnotes[setups=footnote:interlinespace]. Any idea how I can successfully influence my local footnotes globally? Julian

Table of contents not appearing.

Hi, I don't see why the table of contents does not appear. On the other hand, the 12 chapters are present.

missing xml call
by Hans van der Meer 21 Apr '23

21 Apr '23

\xmlatt{}{} has a counterpart \xmlattribute{}{LPATH}{} where one can start the search for the attribute at LPATH. for \xmlchainatt{}{} I am missing such a counterpart \xmlchainattribute{}{LPATH}{} where one can do the same. The problem now is that \xmlchainatt{#1}{att} always finds attribute att when it is defined on the node itself. But consider the case where att="true" exists with the intention to trigger a search higher up in the call chain for that same attribute att. Of course \xmlattribute{#1}{..}{att} is not exactly the same as \xmlchainattribute{#1}{..}{att} would be . yours sincerely dr. Hans van der Meer

Non-standard font alternatives
by Matthew McCabe 20 Apr '23

20 Apr '23

Hi list, I'm looking to import a font with medium and light weights (in this case Roboto) and define font alternatives so one can quickly switch to light text just as one would switch to bold text. There is a stackexchange answer from Wolfgang (https://tex.stackexchange.com/questions/303648/context-font-weights) which details a solution to this problem for ConTeXt MkIV but despite my best efforts I haven't been able to get things to work for me. There is the Roboto typescript example on ConTeXt garden but it isn't exactly what I'm looking for as for the document I'm making I would prefer to be able to treat the font weights as alternatives rather than separate families since I will be switching often. One can download the exact set of fonts I am using from https://fonts.google.com/specimen/Roboto Here is my code: \definefontalternative[lf] % light \definefontalternative[li] % lightitalic \definefontalternative[md] % medium \definefontalternative[mi] % mediumitalic \starttypescript [sans] [roboto] \definefontsynonym [SansLight] [file:Roboto-Light] [features=default] \definefontsynonym [SansLightItalic] [file:Roboto-LightItalic] [features=default] \definefontsynonym [Sans] [file:Roboto-Regular] [features=default] \definefontsynonym [SansItalic] [file:Roboto-Italic] [features=default] \definefontsynonym [SansMedium] [file:Roboto-Medium] [features=default] \definefontsynonym [SansMediumItalic] [file:Roboto-MediumItalic] [features=default] \definefontsynonym [SansBold] [file:Roboto-Bold] [features=default] \definefontsynonym [SansBoldItalic] [file:Roboto-BoldItalic] [features=default] \definefontsynonym [SansCaps] [file:Roboto-Sans] [features=smallcaps] \stoptypescript \starttypescript [sans] [roboto] \definebodyfont [default] [rm] [lf=SansLight sa 1, li=SansLightItalic sa 1, tf=Sans sa 1, it=SansItalic sa 1, md=SansMedium sa 1, mi=SansMediumItalic sa 1, bf=SansBold sa 1, bi=SansBoldItalic sa 1, sc=SansCaps sa 1] \stoptypescript \definetypeface[roboto][rm][sans][roboto][default] \setupbodyfont[roboto] \starttext \lf Light \li LightItalic \tf Regular \it Italic \md Medium \mi MediumItalic \bf Bold \bi BoldItalic \sc SmallCaps \stoptext - The result is entirely in the regular weight default font: What I've tried: 1. I've tried a great deal of alternative \definefontsynonym arguments such as specifying by name, including the full path to each ttf file 2. I played around with different two character \definefontalternative arguments to ensure there was no overlap with existing commands (as far as I am aware the existing set are otherwise undefined) A few things to note: 1. My current version of ConTeXt is 2022.12.09 16:34 2. For portability I have included the ttf files for Roboto in a directory within my project directory and while setting things up I set OSFONTDIR to include this directory and run `mtxrun --script fonts --reload --force` 3. `mtxrun --script fonts --list --all --pattern=Robo` yields: identifier familyname fontname filename subfont instances roboto roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotoblack roboto robotoblack ./fonts/Roboto/Roboto-Black.ttf robotoblackitalic roboto robotoblackitalic ./fonts/Roboto/Roboto-BlackItalic.ttf robotobold roboto robotobold ./fonts/Roboto/Roboto-Bold.ttf robotobolditalic roboto robotobolditalic ./fonts/Roboto/Roboto-BoldItalic.ttf robotoitalic roboto robotoitalic ./fonts/Roboto/Roboto-Italic.ttf robotolight roboto robotolight ./fonts/Roboto/Roboto-Light.ttf robotolightitalic roboto robotolightitalic ./fonts/Roboto/Roboto-LightItalic.ttf robotomedium roboto robotomedium ./fonts/Roboto/Roboto-Medium.ttf robotomediumitalic roboto robotomediumitalic ./fonts/Roboto/Roboto-MediumItalic.ttf robotonormal roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotoregular roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotothin roboto robotothin ./fonts/Roboto/Roboto-Thin.ttf robotothinitalic roboto robotothinitalic ./fonts/Roboto/Roboto-ThinItalic.ttf 4. Using `\definedfont[name:robotomedium*default] hello` and `\definedfont[file:Roboto-Thin*default] hello` (for example) work exactly as expected I hope this isn't a silly question, I'm very new to ConTeXt and have been struggling for a while so thought I may as well ask in case there's something I'm missing, would appreciate any guidance :) Regards, Matt
