Font error in PDF using ConTeXt and Kepler typeface
by Werner Schmidt 26 Apr '23

26 Apr '23

Hi all, I'd like to use the commercial Adobe Kepler typeface (Kepler Std - version 2.020) in conTeXt (v2023-04-15) as text (serif) font. Although the font files are loaded correctly (see log below), the generated PDF is unreadable (see attached image). Notes: - Only serif font (keplerstd-light.otf) is not working. It's not embedded in the generated PDF. - italics and bold fonts are embedded and are rendered well - Can't provide font files because Kepler is a commercial typeface Do you have any ideas how to debug this issue? Thanks Werner log file: mkiv lua stats > loaded fonts: 10 files: fontawesome6freesolid900.otf, frutigernextpro-bold.otf, frutigernextpro-regular.otf, iosevka-term-ss09-light.ttf, keplerstd-light.otf, keplerstd-lightcapt.otf, keplerstd-lightit.otf, keplerstd-semibold.otf, latinmodern-math.otf, lmroman10-regular.otf mkiv lua stats > font engine: otf 3.133, afm 1.513, tfm 1.000, 30 instances, 18 shared in backend, 3 common vectors, 15 common hashes, load time 0.449 seconds Example: This text can't be read in PDF.par {it However, italics are working.}par {bold Also Bold and bfem BoldItalics!}par input{zapf}

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 22 Apr '23

22 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
