Harfbuzz plugin and colors
by Jairo A. del Rio 14 Feb '22

Hi, list! I've tested the Harfbuzz plugin in ConTeXt and it works nicely for most cases. However, color doesn't seem to work. Is this intended? I know this plugin won't be supported, but I'll be fine with pointers to solve this issue. Thanks in advance. \usemodule[fonts-plugins] \definefontfeature[harf] [mode=plug, features=harfbuzz, shaper=native] %Just to test Harfbuzz is actually working \definefontfeature[devaA][harf] [language=dflt, script=deva] \definefontfeature[devaB][default] [script=deva] \definefontfeature[colored][harf] [language=dflt,script=arab, colr=yes] %doesn't do anything \startbuffer[hindi] %From a Wikipedia page हिन्‍दी भाषा का इतिहास लगभग एक सहस्र वर्ष पुराना माना गया है। हिन्‍दी भाषा व साहित्‍य के जानकार अपभ्रंश की अन्तिम अवस्‍था 'अवहट्ठ से हिन्‍दी का उद्भव स्‍वीकार करते हैं। चन्द्रधर शर्मा 'गुलेरी' ने इसी अवहट्ठ को 'पुरानी हिन्दी' नाम दिया। अपभ्रंश की समाप्ति और आधुनिक भारतीय भाषाओं के जन्मकाल के समय को संक्रान्तिकाल कहा जा सकता है। हिन्दी का स्वरूप शौरसेनी और अर्धमागधी अपभ्रंशों से विकसित हुआ है। 1000 ई॰ के आसपास इसकी स्वतन्त्र सत्ता का परिचय मिलने लगा था, जब अपभ्रंश भाषाएँ साहित्यिक सन्दर्भों में प्रयोग में आ रही थीं। यही भाषाएँ बाद में विकसित होकर आधुनिक भारतीय आर्य भाषाओं के रूप में अभिहित हुईं। अपभ्रंश का जो भी कथ्य रूप था - वही आधुनिक बोलियों में विकसित हुआ। \stopbuffer \starttext {\righttoleft\definedfont[file:AmiriQuranColored.ttf*colored]\input{khatt-ar}} {\definedfont[file:Lohit-Devanagari.ttf*devaA]\getbuffer[hindi]} \blank[line] {\definedfont[file:Lohit-Devanagari.ttf*devaB]\getbuffer[hindi]} \stoptext

Indented Paragraph After Float?
by Michael Urban 08 Feb '22

08 Feb '22

As always, it is hard to tell whether this is my stupidity, the wrong version of ConText, or a bug. \setupfloat[figure][indentnext=yes] \starttext %\setupbodyfont[11pt] \setupindenting[yes, medium] \input ward \startplacefigure[title=A Figure,location=page] \startframedtext \input ward.tex \stopframedtext \stopplacefigure Why am I not indented? \input ward \stoptext produces output (for me) with the next paragraph after the figure placement unindented. I cannot think of a workaround hack in this case. mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /usr/local/texlive/texmf-local/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.03.10 14:44 mtx-context | main context file: /usr/local/texlive/texmf-local/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.03.10 14:44

Hi, In case I forget (and someone is in wikify mode) ... the next upload will have a new command: test \diagnostic {here 1} test test \diagnostic[2] {here 2} test test \diagnostic[.05]{here 3} test which will show up as [[diagnostic]] > here 1 [[diagnostic]] > here 2 (sleep: 2) [[diagnostic]] > here 3 (sleep: 0.05) and which can be used for debugging styles. It might evolve.

Regular Online meeting
by Gerhard Schramm 08 Feb '22

08 Feb '22

Dear Hraban, Dear Hans I'm looking for a way to automatically rotate a graphic (DIN_A4_PDF_Pages). I try to manage technical manuals with Context. (Which is really great!) To do this, I have to import always new PDF-pages (technical sketches) , which can be in landscape or portrait format. The pages should always be displayed as large as possible on the pages of my manuals. (I have no influence on the PDF's, as they come from other departments.) Do you see a possibility here? kind regards Gerd

Double-sided documents with MetaFun's Field[Text][Text]
by śrīrāma 07 Feb '22

07 Feb '22

Dear list, I have a double-sided document in which I want to draw certain page backgrounds on the right (odd) and left (even) pages. Here is an example %%% SOF \setuppagenumbering[alternative=doublesided] \setuplayout [backspace=4cm, leftmargin=4cm, cutspace=2cm, rightmargin=2cm, leftmargindistance=0cm, rightmargindistance=0cm, header=2cm, footer=2cm, topspace=1cm, bottomspace=1cm, top=1cm, bottom=1cm, width=middle, height=fit] \startuseMPgraphic{page} StartPage; draw Area[Text][Text] shifted (InnerMarginWidth,BottomHeight+FooterHeight); draw Field[Text][Text] withcolor blue; StopPage; \stopuseMPgraphic \defineoverlay[page][\useMPgraphic{page}] \setupbackgrounds[page][background=page] \starttext \dorecurse{10}{\input knuth \page} \stoptext %%% EOF In the resulting PDF the Field[Text][Text] path is not positioned (/computed?) correctly, while the manually positioned Area[Text][Text] path is as expected. So, it seems that the margin widths and other distance are updated for each odd, even page but Field[Text][Text] is still wrong? The Field[Text][Text] path appears on every page as though it is on an odd (right) page. Have I missed something? Thanks, śrīrāma (Sreeram)

Odd Font Behavior in startstop Group
by Michael Urban 06 Feb '22

06 Feb '22

I am experiencing an odd behavior switching text styles in a defined startstop group ("blockquote"). I get different behavior depending on whether the switchtobodyfont in the startstop definition includes the dummy {\it } and {\bf } text. If they are not there, the italic and boldface switches in the second blockquote revert to the gyreschola body font of the main text; but this only happens if there is an earlier blockquote with no style changes. This is with: $ context --version mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /usr/local/texlive/texmf-local/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.03.10 14:44 mtx-context | main context file: /usr/local/texlive/texmf-local/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.03.10 14:44 Do I need a newer version of ConTeXt, or am I doing something wrong? Fonts in ConTeXt are always perilous, alas. For me, anyway. \definefallbackfamily[story][serif][notoserif][range={greekandcoptic,greekextended},force=yes] \definefontfamily[story][serif][TeX Gyre Schola] \definefontfamily[story][sans][modern] \definefontfamily[story][mono][modern] \definefontfamily[story][mm][TeX Gyre Pagella Math] \setupbodyfont[story,11pt] \definestartstop[blockquote] [ before={ \blank \startnarrower \setupwhitespace[2pt] \setupindenting[none] \switchtobodyfont[termes]{\it }{\bf }% This is so weird.

XMP metadata schema yields invalid PDF/A
by Karl Pettersson 05 Feb '22

05 Feb '22

Hi PDF/A files generated using ConTeXt fail validation with veraPDF, and the reason seems to be that the dc:description metadata is defined with the wrong type in the embedded XMP extension schema. https://tex.stackexchange.com/questions/632380/generate-pdf-a-with-context https://github.com/veraPDF/veraPDF-library/issues/1224 I can reproduce the problem using TeX Live 2021 (MkIV 2021.03.05). The definition seems to be controlled by this code. https://source.contextgarden.net/tex/context/base/mkiv/lpdf-pua.xml?search=… Regards -- Karl Pettersson Uppsala, Sweden https://static-dust.klpn.se/

Transliteration
by Ivan Pešić 03 Feb '22

03 Feb '22

Hello! I've been working on a Serbian book and I had to transliterate it from cyrillic to latin. There's been some nice improvement in transliteration, and I would like to propose a small change. One of the peculiarities that current transliteration mechanisms (both internal one and the 3rd party module from Philipp Gesang) don't process is that Љ, Њ and Џ are transliterated to Lj, Nj and Dž in normal words that start the sentence, or in names that normally start with a capital letter, but in titles written in all capitals they should be transliterated to LJ, NJ and DŽ. So, the quick solution was to update the current mapping vector and add another one (that is attached) that maps cyrillic capitals to LJ, NJ and DŽ and set the correct 30 letters used in Serbian language. It requires a bit more manual work to set the correct mapping for all capitals text, but it works. I have also merged the Serbian hyphenation patterns, so there is no need to switch the language in order to have hyphenation in transliterated text. That was possible because cyrillic and latin scripts use different code points, and there are no conflicts in patterns. So I suggest merging the patterns for Serbian cyrillic and latin. There is another issue if one wants to use a dropcap and the rest of that first word, and several following words are to be typeset in small caps. If that first letter is Љ (or other two letters that transliterate as digraphs), then the second letter of the digraph is not typeset in small caps because it gets injected before the group that turns on small caps. For example: \placeinitial Љ{\sc уди нису знали} but this is quite a special case... Regards, Ivan
