PDF/A conformance
by Denis Maier 22 Sep '20

22 Sep '20

Hi, I need to produce PDF/a. I've followed the advice on the Wiki, and the file validates with: https://www.pdf-online.com/osa/validate.aspx But Acrobat complains about some problem with the XMP definition. Does anyone know more about this? Best, Denis

More table questions
by Denis Maier 22 Sep '20

22 Sep '20

Hi, I usually don't need tables, therefore this maybe stupid question: What is the currently recommended way to typeset tables? Still natural tables? Or extreme tables? (My tables won't be 30 pages long.) Also, how do you easiest define booktabs style tables? I mean: can you define tables such that the last row end with thicker lines without having to make this explicit? Is there a mechanism for this? (That would make the XML mapping much simpler.) Best Denis

Judeo-Arabic punctuation
by Denis Maier 22 Sep '20

22 Sep '20

Hi, I'm getting weird punctuation with a judeo-arabic text: ==================== %This gives correct results \definefontfamily[hebrew][rm][SBL Hebrew] [range=hebrew, force=yes, features=hebrew] \setupbodyfont[hebrew] % This doesn't %\definefallbackfamily[mainface][rm][SBL Hebrew] [range=hebrew, force=yes, features=hebrew] %\definefontfamily[mainface][rm][Tex Gyre Pagella] %\setupbodyfont[mainface] \setupalign[r2l] \setupdirections[bidi=global,method=unicode] \starttext פאדא וג̇ד אפעאל אללה תעאלי עלי ג̇איה̈ אלאחכאם ואלאתסאק נחו כלקה̈ אלאנסאן עלי עג̇יב צורתה ותכֿטיטה̈ וחואסה ומג̇ארי טעאמה ושראבה ותרכיב(ה) אעצ̇איה ותרתיבהא פי אמאכנהא וכמה קאל אלואלי ע׳אלס׳ הלא כֶֿחָלָבֿ ת[ת]יכֵֿני וכגבינה תקפיאני. עור ובשר תלבי[שני] ובעצמות וגידים תסוככני חיים וחסד [עשי]ת עמדי. ופקדתך שמרה [רוחי]. \stoptext =============================== The first setting produces correct punctuation. The second setting works well with regular Hebrew text, even with punctuation. But the special diacrital marks needed for judeo-arabic texts are misplaced with this settting. (I can only guess, but it has probably to do with the Unicode range that is covered by `range=hebrew`.) Best, Denis

ZapfDingbats Unicode differences MKIV vs LMTX
by Christoph Reller 22 Sep '20

22 Sep '20

Dear List, I have the following MWE: \definefontsynonym[ZapfDingbats][file:ZapfDingbats][features=dingbats] \usemodule [fnt-10] \starttext (1) \getglyphdirect{ZapfDingbats}{61491}\crlf % MKIV log: char  (U+0F033) in font 'ZapfDingbats-4' with id 8: missing (2) \getglyphdirect{ZapfDingbats}{983059} % LMTX log: char 󰀓 (U+F0013) in font 'ZapfDingbats-4' with id 8: missing \ShowCompleteFont{name:ZapfDingbats}{14pt}{1} \stoptext In MKIV, line (1) fails to output the requested glyph, while line (2) produces a "check" (✓). In LMTX, line (2) fails and line (1) produces the "check" (✓) . The output of "\ShowCompleteFont" reports differing Unicodes for the same glyphs. Apparently the Unicodes for ZapfDingbats have changed. I would like to have a "check" (✓) in the output for both MKIV and LMTX. Options: A) Is there a way to address the glyph in ZapfDingbats for both MKIV and LMTX uniformly, e.g. by glyph index? (By glyph name does not seem to work: MKIV reports glyph names, LMTX does not.) B) Is there a conditional that I can build into the source to distinguish between MKIV and LMTX? C) Is there a font in the distribution for which I can have a "check"-symbol in both MKIV and LMTX? Any help is appreciated! Cheers, Christoph

How to get the last item from an XML node
by Denis Maier 22 Sep '20

22 Sep '20

Hi struggling again: Shouldn't the code below give me the last element under <tbody>? Right now \xmlfilter{#1}{/tr/last()/command(xml:table:tbody:tr)} gives me nothing... (Use case is that I want to have a frame above the table and one bar below. So I think I should wrap the last line in the \startxtablefoot ...\stopxtablefoot, i.e., I need one command for the last element, and one for the rest (Or is there a better way?). What would be the everything but the last? What am I missing? Thanks again, Denis ================== \setupxtable[frame=off,split=yes] \setupxtable[head][topframe=on,bottomframe=on] \setupxtable[body][] \setupxtable[foot][bottomframe=on] \startbuffer[test] <?xml version="1.0" encoding="utf-8" ?> <article> <table> <tbody> <tr> <td>5</td> <td>A</td> </tr> <tr> <td>7</td> <td>B</td> </tr> <tr> <td>2</td> <td>C</td> </tr> </tbody> </table> </article> \stopbuffer \startxmlsetups xml:test \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{article}{xml:*} \xmlsetsetup{#1}{table}{xml:table} \stopxmlsetups \xmlregistersetup{xml:test} \startxmlsetups xml:article \starttext \xmlflush{#1} \stoptext \stopxmlsetups \startxmlsetups xml:table \startembeddedxtable \xmlfilter{#1}{/tbody/command(xml:table:tbody)} \stopembeddedxtable \stopxmlsetups \startxmlsetups xml:table:tbody \xmlfilter{#1}{/tr/last()/command(xml:table:tbody:tr)} \stopxmlsetups \startxmlsetups xml:table:tbody:tr \startxrow \xmlfilter{#1}{/td/command(xml:table:tbody:tr:td)} \stopxrow \stopxmlsetups \startxmlsetups xml:table:tbody:tr:td \startxcell \xmlflush{#1} \stopxcell \stopxmlsetups \xmlprocessbuffer{test}{test}{} ==================

Re: [NTG-context] \dorecurse{}{} problem
by Jeong Dal 21 Sep '20

21 Sep '20

Dear Aditya, Jairo, Wolfgang, and Otared, Thank you for the replies and explanations. I also read the blog. In this case, using '##1’ is an easy way. For more complex table, I may use luacode. Thanks again. Best regards, Dalyoung

\dorecurse{}{} problem
by Jeong Dal 21 Sep '20

21 Sep '20

Hi, I tried to make a table using \dorecurse or \doloop as in the example. There is no error but \recurselevel is not increased, all are 0 in the first example and only two rows are created with the \recurselevel 0 and 2 only in the second example. Does the tabulate cause the error? What is wrong in this MWE? Thank you for reading.

Math fonts for Nimbus fonts
by Otared Kavian 21 Sep '20

21 Sep '20

Hi, I wish to use the Nimbus fonts, but since I didn't know which Math fonts is best adapted to this family, I tried several fonts such as Stix Math, TeX Gyre Math, and so on, but doing this the math-italic does not appear in these fonts: does this mean that I have to set explicitely math-italic in definefontfamily? Also what is the best math font adapted for Nimbus? Below is my definition of a fontfamily for Nimbus fonts. Thanks in advance for any help: Otared K %% begin definefontfamily-nimbus.tex \definefontfamily [mainface] [rm] [Nimbus Roman No9 L] \definefontfamily [mainface] [ss] [Nimbus Sans L] [rscale=0.85] \definefontfamily [mainface] [tt] [Nimbus Mono] [features=none,rscale=0.95] \definefontfamily [mainface] [mm] [STIX Math] %\definefontfamily [mainface] [mm] [Asana Math] %\definefontfamily [mainface] [mm] [Lucida Bright Math OT] %\definefontfamily [mainface] [mm] [TeX Gyre Termes Math] %\definefontfamily [mainface] [mm] [XITSMath] \setupmathematics[integral=nolimits,lcgreek=normal,default=normal] \setupbodyfont[mainface] \starttext {\rm\tf Regular \it Italic \bf Bold \bi BoldItalic} {\ss\tf Regular \it Italic \bf Bold \bi BoldItalic} {\tt\tf Regular \it Italic \bf Bold \bi BoldItalic} And here are a few math formulas $\alpha^2 + \beta^2 + \gamma^2 = x^2 + y^2 + t^2$. \startformula \int_{0}^{2\pi} \sin(x)dx = 0, \qquad {\rm e}^{{\rm i}\pi} + 1 = 0, \qquad \sum_{n=1}^{\infty}{1 \over n^2} = {\pi^2 \over 6}. \stopformula \stoptext %% end definefontfamily-nimbus.tex

Extreme tables and XML conflict?
by Denis Maier 21 Sep '20

21 Sep '20

Hi, I'm a bit confused, but this here won't compile: ================= \startbuffer[test] <?xml version="1.0" encoding="utf-8" ?> <article> Test <table/> </article> \stopbuffer \startxmlsetups xml:test \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{article}{xml:*} \xmlsetsetup{#1}{table[@content-type!='parallel']}{xml:table} \stopxmlsetups \xmlregistersetup{xml:test} \startxmlsetups xml:article \starttext \xmlflush{#1} \stoptext \stopxmlsetups \startxmlsetups xml:table \startxtable \startxrow \startxcell one \stopxcell \startxcell two \stopxcell \stopxrow \stopxtable \stopxmlsetups \xmlprocessbuffer{test}{test}{} ================ The process just stops in the middle.
