issue with annotation flags
by Pablo Rodriguez 27 May '17

27 May '17

Dear list, I have the following code: \setupinteraction[state=start, color=] \enabledirectives[references.border] \starttext \startTEXpage[offset=1em] \useURL[url1][http://some-url.com]\from[url1] \stopTEXpage \stoptext The annotation code in the PDF file reads: << /Subtype /Link /A 7 0 R /Rect [12.354 10.896 131.607 25.324] /C [0.6 0.6 0.6] /F 4 /Border [0 0 0.5]>> I need to report a bug in a PDF viewer with printing the annotation (in this case, it is only border). The code that generates the annotation is (with some removals): local plus = { -- /F Invisible = 2^0, -- 1 Hidden = 2^1, -- 2 Print = 2^2, -- 3 NoZoom = 2^3, -- 4 NoRotate = 2^4, -- 5 NoView = 2^5, -- 6 ReadOnly = 2^6, -- 7 Locked = 2^7, -- 8 ToggleNoView = 2^8, -- 9 LockedContents = 2^9, -- 10, } I assume that /F is set to NoZoom in the sample above (bit position 4). Acrobat displays the annotation flag set to NoZom. The developers assume that 4 is actually the decimal conversion for a binary number (100, actually bit position 3). So it prints the annotation border in the sample above. It took me a while to understand this (math is all Greek to me). Is there a way that I can set the annotation flag in the sample above to Print (/F 3)? (This would be unambiguous, since only a bit can be set [11 would be an invalid flag value].) Or am I missing something and Acrobat is misbehaving? Sorry for such a weird request, but bug reporting has become extremely complex these days ;-). Many thanks for your help, Pablo -- http://www.ousia.tk

Re: [NTG-context] problem with mathmode in footnotes
by Alan Bowen 27 May '17

To recap: the aim is to get oldstyle numerals in mathmode using TeX Gyre Termes otherwise; \definefontfamily[mainface][serif][TeXGyre Termes][features=f:oldstyle] \definefallbackfamily[mainface][mm][TeX Gyre Pagella] [preset=math:digitsnormal, features=f:oldstyle, scale=0.93] \definefontfamily[mainface][mm][TeXGyre Termes Math] \setupbodyfont[mainface,10pt] 123456789 Euclid \emph{Elem}.\ 3.20 states that if $BC$ is joined to the center $O$ of the circle, then $\angle BOC = 2\cdot\angle A$, and $\angle BOC$ is equal to arc $BC$, that is, $BC\kern-1em\raise1.8ex\hbox{\frown}$.% \footnote{\m{123456789} Euclid \emph{Elem}.\ 3.20 states that if $BC$ is joined to the center $O$ of the circle, then $\angle BOC = 2\cdot\angle A$, and $\angle BOC$ is equal to arc $BC$, that is, $BC\kern-1em\raise1.8ex\hbox{\frown}$.} \stoptext in mathmode in the footnote, ones gets: (a) oldstyle numerals (from Pagella) but no math symbols etc (b) if the line preset=math:digitsnormal is commented out, math symbols etc but but regular numerals. I am using the latest beta of the standalone (05.15.2017).

I think you need to use \insertpages instead. Check this out: http://wiki.contextgarden.net/Command/insertpages Andrés Conrado Montoya http://chiquitico.org

Placing of integral limits
by Mathias Schickel 25 May '17

25 May '17

Dear list, I think that the placement of the indices of integrals has some issues, at least in some fonts. If you try \setupbodyfont[cambria] % \starttext % \startformula % \int\nolimits_a^b f % \stopformula % \stoptext or if you replace Cambria by Stix Two using \setupbodyfont[stixtwo], you will notice that the index a is placed a little too far away form the integral sign. The reference is the „exponent“ b and the Word output. I think the Word output should be the reference here because the font design of Cambria is done by Microsoft and Word supports the font as intended. Apart form that you see the very same effect using Latin Modern and this font should look similar to Computer Modern in LaTeX. Best regards Mathias

\start pagefigure not working as expected
by cryo shock 25 May '17

25 May '17

Hi guys, I created a CTX document and now I am trying to merge it with two other pages from another (already compiled) pdf document. Usually I did this job with PDF Split And Merge software, but if CTX (mkiv, LuaTeX) is capable of doing the job, I'd be glad to use CTX instead. On the wiki I found a code snippet that sounds promising, as I don't want headers, page numbers etc. on the two merged pages: \startpagefigure[file.pdf][page=1]\stoppagefigure So I added another line with page=2 as content, yet the output generates a PDF with the *first page twice* only. In fact, my precompiled doc has 3 pages, of which I want the first two only in my new PDF, even when I use the following code, LuaTeX generates the first page of the precompiled PDF *three times*: \startpagefigure[file.pdf][page=3]\stoppagefigure \startpagefigure[file.pdf][page=1]\stoppagefigure \startpagefigure[file.pdf][page=5]\stoppagefigure Like I mentioned: even although there is no 5th page in file.pdf, LuaTeX pastes the first page three times... Am I overlooking something or was there some undocumented change to the code? Thanks in advance, Sebastian

issue with signature field
by Pablo Rodriguez 25 May '17

25 May '17

Dear list, some time ago, Hans implemented signature fields: \setupinteraction[state=start] \starttext \definefield[x][signature] \field[x] \stoptext I’m afraid I’m not able to sign it using Acrobat 9.5.5, which is the latest version released for Linux. Acrobat Reader 9.5.5 is able to sign this document: https://bugs.ghostscript.com/attachment.cgi?id=11678 (and https://bugs.ghostscript.com/attachment.cgi?id=11707). I guess it may not be the cause, but which is the way to force the document to be written in PDF version 1.6? Many thanks for your help, Pablo -- http://www.ousia.tk

setupitemgroup and 'command='
by Thomas Floeren 24 May '17

24 May '17

Hi, I used to use the “command=” parameter when setting up itemize. Now I noticed that it introduces a spurious horizontal whitespace after the item symbol when the item is of type “\sym{}”. I also noticed that the problem goes away if I use “inner=” instead of “command=”. Example: \setuppapersize [A6] \starttext \start \setupitemize [each][command={\setupwhitespace[none]}] With \type{\command=} \startitemize \item \dorecurse{20}{bla } \sym{Y} \dorecurse{20}{bla } \stopitemize \stop \setupitemize [each][inner={\setupwhitespace[none]}] With \type{\inner=} \startitemize \item \dorecurse{20}{bla } \sym{Y} \dorecurse{20}{bla } \stopitemize \stoptext This is with ConTeXt 2017.05.15 21:48. With an older ConTeXt, for example 2015.01.13 15:54, “inner=” and “command=” deliver identical, correct results. So, I’m asking, has “command=” been deprecated or is it just a bug? Or was I using it the wrong way, and “inner=” is the only correct parameter in the example above? Thanks for any info, Best wishes, – Tom -- For macOS: http://dflect.net/context-typeset-tool/

APA Bibliographic refs. | Hyphenated first names | Lower case first letter of Title
by Richard Mahoney | Indica et Buddhica 23 May '17

23 May '17

Dear list, I have been cleaning up the following proof-of-concept edition set with ConTeXt ver: 2017.05.15 21:48 MKIV beta: http://indica-et-buddhica.org/siksasamuccaya-progresse-bodhisattva-concept.… On the whole I'm very pleased but I'm noticing something odd with the APA typesetting. This can be seen on concept:226 & 229. Here is my set up followed by the BibTeX refs.: % Bibliographic referencing \usebtxdataset[thesis-clean-k-final.bib] \setupbtx[default:cite][alternative=num] \setupbtx[apa:cite][alternative=authoryear,compress=yes] \usebtxdefinitions[apa] \definebtxrendering[apa][specification=apa,sorttype=authoryear,numbering=no] \setupbtxlist[apa][alternative=paragraph,width=325pt,maxwidth=325pt,distance=.5em,margin=3em,align={hz,hanging}] 1.) For Hans-Georg and Jens-Uwe I'm getting H. -G. & J. -U. not H.-G. & J.-U.: @Book{gadamer:truth, author = "Hans-Georg Gadamer", title = "Truth and Method", publisher = "Seabury Press", shorttitle = "Truth", year = 1975, address = "New York", key = "gadamer:75", } @InCollection{klaus:einige, author = "K. Klaus", title = "Einige {t}extkritische {u}nd {e}xegetische {B}emerkungen {z}u {Ś}ānti\-devas “{Ś}ikṣāsamuccaya” (Kapitel {XII} {u}nd {XIII})", booktitle = "Bauddhaviyāsudhākaraḥ\,: Studies in Honour of Heinz Bec\-hert on the Occasion of His 65th Birthday", shorttitle = "\,‘{Ś}ikṣāsamuccaya’\,", key = "klaus:97a", pages = "397--406", publisher = "Indica et Tibetica", year = 1997, editor = "P. Kieffer-Pülz and Jens-Uwe Hartmann", volume = 30, address = "Swisttal-Odendorf", } 2.) And for the initial letter of the title, SGam.po.pa not sGgam.po.pa: @Book{guenther:sgam, title = "{s}{G}am.{p}o.{p}a, The Jewel Ornament of Liberation\,: {D}am.\-{c}hos {y}id.{b}žin.{g}yi {n}or.{b}u {t}har.{p}a {r}in.{p}o {c}he'i {r}gyan {ž}es.{b}ya.{b}a {t}heg.{p}a {c}hen.\-{p}o'{i} {l}am.{r}im.{g}yi {b}śad.{p}a", publisher = "Rider \& Co.", shorttitle = "{s}{G}am.{p}o.{p}a", year = 1970, key = "guenther:70a", address = "London", author = "H. V. Guenther", } I've also tried surrounding the hyphenated names, and their initials, with curly brackets, though without success. Does anyone know how I might be able to correct this?
