Re: [NTG-context] problem with a new installation of LMTX
by Jeong Dal 08 Dec '19

08 Dec '19

For test, I installed again after removing ConTeXtLMTX folder. But it is same as before. I looked files in “/tex/texmf-osx-64/bin”. There are 5 files: context, context.lua, luametatex, mtxrun, mtxrun.lua. context and mtxrun are symbolic linked to luametatex. But luametatex is not executable, so I changed it using “chmod 755 luametatex”. I run “mtxrun —generate”, then it set variables as follows: % mtxrun --generate resolvers | resolving | variable 'SELFAUTOLOC' set to '/usr/local/texlive/2019/bin/x86_64-darwin' resolvers | resolving | variable 'SELFAUTODIR' set to '/usr/local/texlive/2019/bin' resolvers | resolving | variable 'SELFAUTOPARENT' set to '/usr/local/texlive/2019' resolvers | resolving | variable 'TEXMFCNF' set to '' resolvers | resolving | variable 'TEXMF' set to '' resolvers | resolving | variable 'TEXOS' set to 'bin' resolvers | resolving | ……. and do many things in the texlive/2019 folders. My question is that luametatex is distributed as an inexecutable form deliberately? Thank you for reading. Best regards, Dalyoung

Noto Emoji fonts
by Pablo Rodriguez 08 Dec '19

08 Dec '19

Hi Hans, which is the way I can get the glyphs from the second line in the following sample? \definefontfamily[emoj][rm][Noto Emoji] \setupbodyfont[emoj] \starttext 🔔💻🔨🔩 󾓧󾓨󾓩󾓪󾓫󾓬󾓭󾓮 \stoptext Would it be possible that Noto Color Emoji font works with ConTeXt? I think this is handy, since they are useful in presentations. In fact, I need one flag (in the second line form the sample) for one presentation. Many thanks for your help, Pablo -- http://www.ousia.tk

issue with beta from 2019.11.29 21:47 in Windows
by Pablo Rodriguez 07 Dec '19

07 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

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
by Pablo Rodriguez 06 Dec '19

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!
