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

Accessibility and Tagged PDF/A, Footnotes showing
by Ursula Hermann 19 Jan '16

19 Jan '16

Hello Hans and Dr. Dominik Klein! Today I found a Thread about Accessibility from last Juli! I work at the University in Vienna, and I work with students, who are blind or have a see handicap. So I read this Thread today. Last year in Summer I began to read the manual of Context. I have a question to this discussion, it is nessesary to know: How can footnotes be shown in the PDF/A tagged PDF, in a text? What I mean something, that shows in the Text the text from the footnote, when I click on the number from the footnote. Maybe with a tooltip? Or what is the right way? Which command? Ursula Hermann

TeX in \xmlsetentity and DTDs in DOCTYPEs
by Kate F 19 Jan '16

19 Jan '16

Hi. I'm using MkIV's XML stuff. I have two related questions. Firstly, can I have entities in XML expand out to TeX markup? I thought this was how you'd do it, but this produces a document that says literally "xxx~yyy\thinspace zzz", whereas I want the ~ and \thinspace to be executed as TeX commands. Test case below. Secondly, is it possible to have ConTeXt load such entities from a DTD? If I use a DOCTYPE in my XML, entities from that DTD seem to not be loaded. Thanks. a.xml: <?xml version="1.0"?> <a>xxx yyy zzz</a> a.tex: \startxmlsetups xml:mysetups \xmlsetsetup{\xmldocument}{a}{xml:*} \stopxmlsetups \xmlregistersetup{xml:mysetups} \startxmlsetups xml:a \xmlflush{#1} \stopxmlsetups \xmlsetentity{nbsp}{~} \xmlsetentity{thinsp}{\thinspace} \starttext \xmlprocessfile{main}{a.xml}{} \stoptext -- Kate

\replaceword and \setreplacements with xml files
by Jan U. Hasecke 18 Jan '16

18 Jan '16

Dear list, some time ago I ask for a way to selectively suppress ligatures. Hans told me to use the replacement feature. - http://www.ntg.nl/pipermail/ntg-context/2015/083044.html - http://www.ntg.nl/pipermail/ntg-context/2015/083034.html In another thread a solution with the translate module was shown http://tex.stackexchange.com/a/37465/323 http://tex.stackexchange.com/a/28746/323 Both solutions work fine if I use them in a simple context file, but I can't use neither solution in my xml processing. I use a customized version of the from-pandoc-to-context solution of Pablo. When I place the replacement commands somewhere in the style file I get no result. I can see no error message. The file is compiled just fine but without replacements. Has anyone yet implemented replacements in xml processing and can give me a hint where to place the commands? TIA juh

RTL problem with figure numbers
by Mohammad Hossein Bateni 18 Jan '16

18 Jan '16

Hi, Again this has been partly discussed on the list and solutions were already there but I didn't see anyone mention the issue with figures. In the following MWE we have 20 pages of a simple text with a section, a footnote and a figure on each page. The page numbers and footnote numbers are fine. Section numbers need some care to appear correctly. I couldn't figure out a similar mechanism for figure numbers, though. The example does not use Indic numbers, which does not have any effect on the problem. \setupdirections[bidi=global,method=two] \setupalign[r2l] %% If we don't provide the numbercommand, we'll see reverse numbering starting from 10. \setuphead[chapter,title,section,subject][numbercommand=\righttoleft] %% The following does not accept any numbercommand but it has numberconversion. %% As a result figure numbers are shown in reverse. \setupcaptions[numberstopper={:}] %% Footnotes are fine and accept conversion. %% Page numbers are also okay. \starttext \dorecurse{20}{ \section{Test} This is a very simple text. And we have a footnote\footnote{Footnote text}. \placefigure [][] {Test figure.} {\centerline{FIGURE BODY}} \page } \stoptext I use TeXLive 2015 on Mac OS X, CONTEXT 2015.05.18 12:26, and LuaTeX, Version beta-0.80.0 (TeX Live 2015) (rev 5238). Thanks a lot! —MHB

Binaries for Linux (warning)
by Mojca Miklavec 18 Jan '16

18 Jan '16

Hi, Alan now tried compiling the luatex binaries for Linux on Debian rather than on some ancient CentOS (like he did in the past). In case that any Linux user experiences problems, please let us know and we'll switch back to CentOS with an older libc, otherwise we would prefer to stick with Debian (oldstable). Mojca

xtables doesn't work in CLD
by Romain Diss 18 Jan '16

18 Jan '16

Hi all, I am trying to use xtables in a CLD document but when I add a row, it doesn't compile anymore. Is there something wrong? If xtables is not usable with CLD, what is the best set of table commands to use with CLD? % Minimum not working example : context.starttext() context.startxtable() context.startxrow() context.startxcell() context("Test") context.stopxcell() context.stopxrow() context.stopxtable() context.stoptext() % end of the example. All the best. -- Romain Diss
