issue with beta from 2019.11.29 21:47 in Windows
by Pablo Rodriguez 08 Dec '19

08 Dec '19

Dear list, I have the following sample: \def\ThisOption{ab} \def\ThatOption{ábc} \starttext \executesystemcommand{contextjit --purgeall --arguments="OptionThis={\ThisOption},OptionThat={\ThatOption}" second.tex} \contextversion \stoptext The contents of second.tex read: \starttext \enablemode[\env{OptionThis}] \enablemode[\env{OptionThat}] This: \doifmodeelse{ab}{enabled}{disabled}.\par That: \doifmodeelse{ábc}{enabled}{disabled}. \stoptext I use --arguments to pass modes to documents compiled via \executesystemcommand. Everything worked fine. This morning I updated ConTeXt at work (with Win7) and modes with non-ASCII chars aren’t recognized. Could anyone confirm the issue I’m describing in Windows? Is there any ConTeXt command (or Lua function) that translates non-ASCII chars to their ASCII values? Many thanks for your help, Pablo -- http://www.ousia.tk

hz / expansion
by Hans Hagen 07 Dec '19

07 Dec '19

Hi, The latest lmtx has a new feature: expansion control independent of font specific settings. When used the font specific step stretch and shrink will be overloaded. This permits mixed setups that are normally nor possible because these three properties need to be consistent within a paragraph. It also permits local deviations from the defaults, for instance in more extreme cases. \startluacode local classes = fonts.expansions.classes classes.qualityb = { vector = "default", factor = 1, stretch = 8, shrink = 4, step = .5, } classes.qualitya = { vector = "default", factor = 1, stretch = 4, shrink = 2, step = .5, } \stopluacode \showframe % \enabletrackers[*expansion] \setupbodyfont[dejavu,8pt] \defineexpansion [myexpansion] [step=1, stretch=50, shrink=20] \definefontfeature [basea] [default] [expansion=qualitya] \definefontfeature [baseb] [default] [expansion=qualityb] \definefont[FontA][Serif*basea] \definefont[FontB][Serif*baseb] \setupalign[verytolerant,stretch,hz] \starttext \startbuffer \dorecurse {30} {% {\FontB \red test me #1,} \FontA \dorecurse{#1}{test ##1, }% }\par \stopbuffer {\getbuffer \page} \setexpansion[myexpansion] {\getbuffer \page} \stoptext Maybe it's useful (I hardly use expansion myself). Hopefully there are no side effects.

Filling a page with \thinrules
by Otared Kavian 07 Dec '19

07 Dec '19

Hi all, I am preparing a test for my students where I would like to have the statement of the problem on the top of a page and the remainder to the bottom of that page filled with \thinrules, for them to write the solution. And sometimes there might be an empty page filled with thinrules when the solution to the exercise is longer. The following minimal example gives the idea of what I want to achieve, but since the statement of each exercise may be longer or shorter, I would like ConTeXt to compute how many \thinrules can be put in the remainder of the page. That is, can one imagine a macro named (say) \fillpagewiththinrules which puts the exact number of thinrules before ejecting the page? Is this possible or have I to do it by hand for each page? \showframe \starttext \dorecurse{2}{\input knuth.tex\par} \thinrules[n=20] % On the first page I can put 20 thinrules \page \thinrules[n=40] % On an empty page I can put 40 thinrules \page \input ward.tex \thinrules[n=37] % On the third page there can be 37 thinrules \stoptext Thanks for any hint and help, Best regards: Otared K.

PDF/A-3a attachment support query
by Rik Kabel 07 Dec '19

07 Dec '19

Hello list, The following document fails PDF/A-3a validation. It passes without the attachment. \setuplanguage [en] \setuptagging [state=start] \setupinteraction [state=start] \setupbackend [format={pdf/a-3a},profile={default_gray.icc}, intent={ISO coated v2 300\letterpercent\space (ECI)}] \setupstructure [state=start,method=auto] \setupcolors [pagecolormodel=auto,start=yes,rgb=no,cmyk=no] \setupbodyfont [Palatino,10pt] \starttext Attaching a plain text file. % \attachment [file=test.tex, % type={text/plain;charset=UTF-8}] % The \ConTeXt\ source code for this document is attached here. \attachment [file=testa.pdf, type={application/pdf}] A successfully validated pdf/a-3a file is attached here. \stoptext pdf-online <https://www.pdf-online.com/osa/validate.aspx>reports: Validating file "test.pdf" for conformance level pdfa-3a The key F is required but missing. The appearance dictionary doesn't contain an entry. File specification 'testa.pdf' not associated with an object. The document does not conform to the requested standard. The document doesn't conform to the PDF reference (missing required entries, wrong value types, etc.). The document contains hidden, invisible, non-viewable or non-printable annotations. The document contains annotations or form fields with ambigous or without appropriate appearances. The document does not conform to the PDF/A-3a standard. Done. My understanding is that 3-a should support both pdf and non-pdf attachments. This fails in a similar manner with both pdf/a-3a-validated files and with plain text files. I also tested with verapdf, and it also rejected the document with an attachment. Is this my error, or is it not yet supported? -- Rik Kabel

wrong link /Rect in LMTX
by Pablo Rodriguez 07 Dec '19

07 Dec '19

Hans, \setupinteraction [state=start] \enabledirectives[references.border=red] \starttext \startxtable[option=stretch, frame=off] \startxrow \startxcell\goto{\hyphenatedurl{a}}[url(a)]\\ b\stopxcell \stopxrow \stopxtable \stoptext When compiled with LMTX, the link has a /Rect as wide as the cell. MkIV generates the link with the right width. Could you fix it? Many thanks for your help, Pablo -- http://www.ousia.tk

new beta
by Hans Hagen 06 Dec '19

06 Dec '19

Hi, I uploaded a new lmtx beta. Hopefully the installer works ok as I redid some of the "zip" related code (simpler, smaller binary too). FWIW, the luametatex codebase is now pretty close to okay, but of course there can be bugs, but nothing thay can't be solved fast. Given some earlier discussions on the list, I wonder about running context in containers and (behind the screens) web applications. Is there anything needed, mostly in the support scripts I guess, that can make that more comfortable / efficient / etc?

getting character from Noto Emoji

Dear list, with this sample (font available at https://www.google.com/get/noto/) \definefontfamily[emoj][rm][Noto Emoji] \setupbodyfont[emoj] \starttext 🔔💻🔨🔩 󾓥󾓦󾓧󾓨󾓩󾓪󾓫󾓬󾓭󾓮 \stoptext I would like to get the second line of emojis (which are flags). \tochar{n:FE4EB} outputs "4" and \utfchar{0xFE4EB}. What am I doing wrong here? BTW, I would love to use Noto Color Emoji, but ConTeXt (MkIV & LMTX) doesn’t seem to handle it. Many thanks for your help, Pablo -- http://www.ousia.tk

Suppress blank page in asymmetrical multicolumn layout
by Thangalin 06 Dec '19

06 Dec '19

Hi there, How do I suppress the blank page in the following document while maintaining the asymmetrical multicolumn layout? The problem centres around "page=yes," whereby removing it eliminates the blank page, but then wreaks havoc on the document layout. \definepapersize[BookPaperSize][width=24in, height=12in,] \setuppapersize[BookPaperSize] \definelayout[BookTextLayout][ topspace=.5in, backspace=.5in, header=\zeropoint, footer=\zeropoint, grid=yes, ] \setuplayout[BookTextLayout] \definecolumnset[BookColumns][n=4,distance=.25in] \setupcolumnset[BookColumns:1][width=11.75in] \setupcolumnset[BookColumns:2][width=3.46in] \setupcolumnset[BookColumns:3][width=3.46in] \setupcolumnset[BookColumns:4][width=3.46in] \setuphead[section][ page=yes, beforesection={\startcolumnset[BookColumns]}, aftersection={\stopcolumnset}, ] \setuphead[subsection][ after={\column}, ] \setuphead[subsubsection][ after={\blank[small]}, ] \starttext \startsection[title={Section Title}] \startsubsection[title={Subtitle}] \dorecurse{2}{\input knuth} \dorecurse{2}{% \startsubsubsection[title={Subsubtitle}] \dorecurse{1}{\input ward} \dorecurse{2}{\input lorem} \dorecurse{1}{\input bryson} \stopsubsubsection } \stopsubsection \stopsection \stoptext Thank you!

Using ConTeXt with LuaTeX variants
by Jairo A. del Rio 06 Dec '19

06 Dec '19

I want to know if it's possible use HarfTeX/LuaHBTeX with ConTeXt (MKIV), mainly for what can be done with them (the "mode=harf" feature and Lua language features). Although this is pretty easy with LaTeX: \usepackage{harfload} \setmainfont{font}[RawFeature={mode=harf}] I have no idea of how to make it work with context. I've tried the following with a test file (a simple \starttext .. \stoptext document): context tests.tex --engine=luahbtex And this happens: mtx-context | run 1: luahbtex --fmt="/home/coragyps/.texlive2019/texmf-var/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/formats/luatex/cont-en" --jobname="tests" --lua="/home/coragyps/.texlive2019/texmf-var/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/formats/luatex/cont-en.lui" --c:currentrun=1 --c:engine="luahbtex" --c:fulljobname="./tests.tex" --c:input="./tests.tex" --c:kindofrun=1 --c:maxnofruns=9 --c:texmfbinpath="/usr/local/texlive/2019/bin/x86_64-linux" "cont-yes.mkiv" This is LuaHBTeX, Version 1.11.2 (TeX Live 2020/dev) system commands enabled. (Fatal format file error; I'm stymied)mtx-context | fatal error: return code: 256 What should I do? Thank you in advance

Impacts Project
by Thangalin 06 Dec '19

06 Dec '19

Hi list! Thank you for helping to answer so many questions and remove so many roadblocks with my project. The result is a photobook written in Markdown, piped through pandoc to generate ConTeXt code, then stylized using a series of .tex files. The coolest ConTeX part, IMO, is the orange dot in the timeline. Using MetaPost, the date for the timeline is read directly from the document, then plotted relative to the \overlaywidth. Changing the date in the Markdown document winds up repositioning the timeline dot automagically. https://impacts.to/ The book is going to be released under a CC BY 4.0 license, including all the source code necessary to generate the book. Meanwhile, if anyone is interested in nabbing a copy of the PDF, let me know (preferably via the web form). Again, my sincerest gratitude, this project would have been a much more time-consuming and arduous journey without your generous help.
