labeltext via lua
by Andreas Schneider 17 Feb '17

17 Feb '17

Hello, if I define a labeltext via \setuplabeltext[en][test=Something], how can I access that value via lua? (context.labeltext obviously prints the content, but doesn't allow me to use it in lua). As a related side-request: how can I fix expansion in cases like this: \startsectionlevel[title=\labeltext{test}] ... this causes the bookmark to read "test" instead of "Something". \expandafter\startsectionlevel... didn't cut it. Best regards Andreas

png and svg backend in mplib embedded in luatex
by luigi scarso 17 Feb '17

17 Feb '17

We are planning to drop the png and svg backend of mplib embedded in luatex . This means that if test.lua uses the png or svg backend $>luatex --luaonly test.lua will not work anymore as expected. To be clear:, *) metapost and mplib will stay as is now; *) mplib when embedded in luatex will loose the png and svg backend. ConTeXt doesn't use the png and svg backend, and it seems that LuaLateX doesn't use these backend too. So....does anybody use the png or svg backend of mplib embedded in luatex ? -- luigi

yearly current
by Hans Hagen 15 Feb '17

15 Feb '17

Hi, We're getting close to tex live freeze and part of that process is a luatex release as well as a context snapshot. There have been no betas for a while and the reason is that I've been cleaning up some code as well as optimizing some bits. As a consequence it could be that there are some issues with an upcoming luatex / context pair but because there has been no real fundamental changes in the typesetting part problems will be easy to sort out (like using an undefine lua function or so). Anyway, if you are not that adventurous or depend on the current version, you can best make a copy or not update from the garden too eager, just wait till the lists reports no crashes. We will try to fix luatex/context things as fast as possible, Hans Luigi ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

defining bug not setting up blank spaces
by Pablo Rodriguez 14 Feb '17

14 Feb '17

Dear list, I have the following sample: \defineblank[ab][none] \starttext \defineblank[ab][big] a \blank[ab] b \stoptext Am I missing something or is there a reason to force the new definition (instead of the setup) of already defined blank spaces? I mean, if this isn’t a bug, I don’t see the gain in this behavior. Many thanks for your help, Pablo -- http://www.ousia.tk

Problem with Russian letters in itemize
by Vladimir Lomov 14 Feb '17

14 Feb '17

Hello, I'm trying to use Russian (Cyrillic) letters for itemize list but without luck. This is small example to show a problem: ---------------------- 8< --------------------- \mainlanguage[ru] \setupbodyfont[cambria] % \setupbodyfont[computer-modern-unicode] % \setupbodyfont[dejavu] \starttext \startitemize[a] \item первый \item второй \stopitemize \stoptext ---------------------- 8< --------------------- Compilation (typesetting) of the example by context (curr. ver. 2017.01.27) gives a PDF file with Latin letters. According to 'language-mkiv.pdf' (found in texmf-context/doc/context/documents/general/manuals) The \type{alphabetic} converter adapts to the current main language. When a language has no special alphabet, the regular 26 characters are used. the use of Latin letters is expected behaviour if current language has not special alphabet. But Russian alphabet (based on Cyrillic) has differences with Latin one. Did I face a bug or I misunderstand the documentation and I have to use (add?) another command to obtain Russian letters for item? Also, it is possible that I incorrectly use 'setupbodyfont' but I tested all cases shown above and they work fine, expect the fact that 'cambria' case gives me italic variant of font while 'computer-modern-unicode' and 'dejavu' use "roman" font. Thank you in advance, Vladimir Lomov -- Trying to define yourself is like trying to bite your own teeth. -- Alan Watts

frac opentype feature broken by \setbreakpoints[compound]
by MF 14 Feb '17

14 Feb '17

Hello list, I found an interference between the "frac" opentype feature and \setbreakpoints[compound], which make the former fail when you have a numerator more than 2 digit wide. I found it with Adobe Garamond Premier Pro: with \setbreakpoints[compound], when the fraction had a 3-digit (or more) numerator, the denominator stayed high as the numerator (like a superscript). Here I replaced Garamond Premier Pro with the freely available "Lato" font, to let you reproduce the problem. The outcome is different, but still erroneous: \setbreakpoints[compound] makes ConTeXt ignore the "frac" feature at all. Please try this: \definefontfeature[frac][frac=yes] \definefontfamily[default][rm][lato][features=frac] \setupbodyfont[default,rm,11pt] \setbreakpoints[compound] \starttext \addff{frac} 1/3, 1/100, 1/1000, {\setbreakpoints[reset]1633/100}, 2345/12. \stoptext A workaround is a local \setbreakpoints[reset] limited to the fraction. Best regards, Massi

Re: [NTG-context] Bug: \textext inside \*MPinclusions causes error
by Sergey Slyusarev 14 Feb '17

14 Feb '17

> the (subtle) difference between the two [*MPinclusions and **MPinitializations*] is not a bug but a feature If I understood correctly, *MPinitializations affects everything and can't be assigned to a specific instance (or can it?), in some cases (like mine) this difference is not so subtle. Look at the following example (not so minimal): \startMPinitializations picture p; p := image( draw fullsquare scaled 1cm; draw textext("1"); ); \stopMPinitializations \startMPinitializations picture s; s := image( draw (fullsquare rotated 45) scaled 1cm; draw textext("2"); ); \stopMPinitializations \defineMPinstance[foo][initializations=yes] \startMPcode{foo} picture q; q := image( draw fullcircle scaled 1cm; draw textext("3"); ); draw q; \stopMPcode \startMPcode{foo} draw p; draw q shifted (2cm, 0); draw s shifted (4cm, 0); \stopMPcode \defineMPinstance[bar][initializations=yes] \startMPcode{bar} picture r; r := image( draw fullcircle scaled 1cm; draw textext("4"); ); draw r; \stopMPcode \startMPcode{bar} draw p; draw r shifted (2cm, 0); draw s shifted (4cm, 0); \stopMPcode First, it shows why *MPinitializations can't replace *MPinclusions for me (it affects all instances), and second, it silently produces produces some really unexpected results: It looks like it should produce (by line) A circle with "3" inside (yes) A square with "1" inside (yes); A circle with "3" inside again (no, instead it produces circle with "2" inside); A rhombus with "2" inside (no, instead it produces a rhombus with "1") and so on. (tested on http://live.contextgarden.net/) In fact, I failed to declare picture variable inside with text inside one *MPcode environment and pass it to another safely (text either disappears or changes to other text, and this time ConTeXt returns no error), that surely is a bug?
