Re: [NTG-context] Fieldstacks are broken
by Jeong Dal 21 Jan '16

Thanks Hans, Wolfgang, Luigi The new beta with Luatex 0.88 makes \fieldstacks and \startanimation work. The following example of Wolfgang is now working well. \def\MyGraphics#1{% \startMPcode path p,q; p:=fullcircle scaled 72; L:=length p; N:=20; q:=subpath (0,#1/N*L) of p; draw q withcolor red; fill fullcircle scaled 3 shifted point length q of q withcolor blue; setbounds currentpicture to unitsquare shifted (-0.5,-0.5) scaled 75; \stopMPcode} \usemodule[animation] \setupinteraction[state=start] \starttext \startanimation[menu=yes] {\MyGraphics {5}} {\MyGraphics {10}} {\MyGraphics {15}} {\MyGraphics {20}} \stopanimation \stoptext One more question. Is there any convenient way to list \MyGraphics{#1}? I tried \dorecurse, but it just display figures one by one. I also tried lua, but it stops with the error message “unexpected symbol near ‘\'”. \dorecurse{20} {{\MyGraphics {\recurselevel}} \startluacode for i = 1, 20 do context(“{\\MyGraphics <smb://MyGraphics>{i}}”) end \stopluacode Thanks again.

is there a bug in the startappendices commend?
by Matthias Wende 21 Jan '16

21 Jan '16

Hello list, After using the \startappendices command the entire document becomes an appendix. After the command the numbering restarts. Here is a simple example. ----------------------------- \setuplabeltext [appendix=Appendix~] \setuphead [chapter] [page=no] \setuphead [section] [appendixlabel=appendix] \setuplist [section] [label=yes] \starttext \title{Contents} \placelist[title,chapter,section][criterium=all,alternative=c] \chapter{First Chapter} \section{First Section} \chapter{Second Chapter} \startappendices \chapter{Appendices} \section{First Appendix} \stopappendices \stoptext ----------------------------- Thank you, Matthias

Bug: RTL \framed when aligned
by Mohammad Hossein Bateni 21 Jan '16

21 Jan '16

Hello, There seems to be a bug in RTL documents when \framed goes in \leftaligned, \midaligned, or \rightaligned AND corner=round option is used. (I don't know what other options trigger the bug.) Here is the MWE (verified in ConTeXt ver: 2016.01.18 22:21 MKIV beta fmt: 2016.1.19 int: english/english): \setupalign[r2l] \starttext \midaligned \framed[corner=round, width=.5\hsize] {Hello! This is some sample text.} \stoptext It works fine when either corner or midaligned is dropped. With both in, however, the frame appears to the right of the text (no overlap). Thanks! —MHB

RTL columns for itemize
by Mohammad Hossein Bateni 20 Jan '16

20 Jan '16

Hi, Is there a way to typeset \startitemize with columns options, such that columns go from right to left? In the underlying structure \startstopcolumns, there is an option "direction" which can be set to "left" to achieve this. I couldn't figure out how to do this within \startitemize though. \setupalign[r2l] \starttext Hello! \startitemize[columns,three,packed,n] \item One \item Two \item Three \item Four \item Five \item Six \item Seven \stopitemize \stoptext The result looks like the following: !olleH enO .1 ruoF .4 neveS .7 owT .2 eviF .5 eerhT .3 xiS .6 How about \startcombination? Can I use RTL ordering with that, too? This is less important than the above since the labels are usually set manually and one can just use the visual ordering rather than the logical one. (That is, except one tries to get automatic numbering for the figures inside the combination but that's not common at all.) Best, —MHB

Greek diacriticals (combining perispomenon displaced)
by Alan Bowen 20 Jan '16

20 Jan '16

There is an oddity in processing Greek. The combining diacritical perispomenon is not positioned properly, though it appears as it should in the source file. This diacritical is placed properly if one inserts the appropriate character directly. The PDF file produced by this sample shows the problem as it appears using two different Greek fonts. The first entries in each line are incorrect. \definefontfamily[mainface][serif][IFAO Grec Unicode] \setupbodyfont[mainface, 24pt] \definefont[HellenicaCU][file:HellenicaCU.ttf at 24pt] \starttext αῖ %combining diacritical αῖ %char 1FD6 \HellenicaCU{ αῖ %combining diacritical αῖ %char 1FD6 } \stoptext As I review my files, I see that this is a fairly recent problem, though I cannot say exactly when it first occurred. The other combining diacriticals process as they should. Alan

citations
by Meer, Hans van der 20 Jan '16

20 Jan '16

In this version: ConTeXt ver: 2015.12.22 10:50 MKIV beta fmt: 2015.12.27 int: english/english I was able to typeset my bibtex citations with \cite. But in the version of ConTeXt-beta I downloaded recently \cite results in blank. There might have been a mention about this recently, but that is all I can remember. What should I change? I am using \module[oldbibtex] at the moment. My usage is through the macros I add for convenience, it might be them causing the problem Hans van der Meer % Custom setup ================================================================ \def\bibentry#1{% start each reference on the next line \breaktemp\def\breaktemp{\hfill\break}% \noexpand\bibentrypar\cite[data][#1]\strut} % Usage: \footnotecite[citation,citation,.. ][optional text] % \footnotecite[citation,citation,..,][optional text on new line] % \footnotecite[citation,,citation,..][optional text] white within \def\footnotecite{\dodoubleargument\dofootnotecite} % footnotes or endnotes \def\mycitenote{\endnote} % Standard form of citations. \def\breaktemp{} \def\Adofootnotecite[#1][#2]{% \def\bibentrypar{\def\bibentrypar{\par}}% \def\breaktemp{}% \unskip\mycitenote{\processcommalist[#1]\bibentry \doifnotempty{#2}{\space#2\strut\par}}} % Disabling citations altogether. \def\Cdofootnotecite[#1][#2]{\ignorespaces}% % Citations switched on. \def\enablecitations{% \writestatus{HVDM-ONDERWIJS}{citations enabled}% \let\dofootnotecite\Adofootnotecite} % Citations switched off. \def\disablecitations{% \writestatus{HVDM-ONDERWIJS}{citations disabled}% \let\dofootnotecite\Cdofootnotecite} % By default citations are off. \let\dofootnotecite\Cdofootnotecite

Re: [NTG-context] Ligatures in EB Garamond
by Georg Duffner 19 Jan '16

19 Jan '16

Hi Jan, hi Hans, This is the developer of EB Garamond. I’m only now and then reading this list so I only learnt about your troubles now. The way the ligatures are composed simplifies the creation of more ligatures after the same scheme while not blowing up the font by having to create one glyph per ligature combination but only one per component. In fact, it’s not just kerning, like Hans said, but one-by-one glyph substitutions. It might be seen as inconsistency that one feature can be executed in different ways. I know of that problem but it’s not that inconsistent at user level if you use the methods intended by unicode and opentype to deal with breaking up ligatures. The symbol ZWNJ (zero width non joiner) is exactly meant to do this so if you insert it, you should get what you want. What’s more, by inserting ZWNJ you should also be able to benefit from kerning between the non ligated f and the following letter or from contextual alternate forms that fit better than the long bowed f, if you want that. With EB Garamond, this should be true for both, engines that handle ZWNJ correctly or not. By the way, the newly standardized German keyboard layout even has the ZWNJ on it and the norm recommends its use to prevent ligation.

Shall I file a bugreport for this issue? What would be the right words: please provide real ligature glyphs instead of composed ones? EB Garamond is a free font also in the sense free of charge. But what can I expect when I buy a commercial font? I would be quite annoyed when I buy a font which does not provide the features in a way that I can use them in ConTeXt. Is there a font quality page on the Wiki with a feature comparison? juh -- EB Garamond: http://www.georgduffner.at/ebgaramond

10th ConTeXt users' meeting
by Alan BRASLAU 19 Jan '16

19 Jan '16

Happy New Years¹, fellow ConTeXt users, The 10th ConTeXt Meeting will take place on September 25-October 1, 2016 at Het Doevehuis in Kalenberg, about 35 km from Hasselt, the Netherlands. http://meeting.contextgarden.net/2016/ Having been *designated* as a member (and chairman!) of the program committee, I wish to invite everyone to begin thinking about subjects that you would like to contribute and/or to see covered. We will also be celebrating the 20th anniversary of the release of ConTeXt, and, of course, the 10th anniversary of ConTeXt meetings. Start planning now in order to make this meeting a big success. A piece of cake! Alan ---------- ¹ I suppose that it is still legal to extend best wishes for the New Year
