Problem loading a DLL with the latest Ctx beta
by Akira Kakuto 06 Apr '17

> How exactly do you mean to combine "ffi" and > "--shell-escape" to work with latest ConTeXt/LuaTeX? In usual luatex, ffi needs --shell-escape, since ffi is dangerous from the point of view of the security. As you know, ConTeXt allows --shell-escape, so the following works with context test.tex. % % context test.tex % \starttext \placeformula \startformula j_1(2.387) = \startluacode local ffi = require("ffi") ffi.cdef[[ double _j1(double x); ]] local mscrt = ffi.load("msvcrt") tex.print(mscrt._j1(2.387)) \stopluacode \stopformula \stoptext In the above example, a function _j1(x) in msvcrt.dll is evaluated. The msvcrt.dll must be loaded as above, because standard C library is linked statically. The following DLLs can be used without loading, because luatex knows them: SHLWAPI.dll WSOCK32.dll USER32.dll ADVAPI32.dll SHELL32.dll KERNEL32.dll WS2_32.dll GDI32.dll Note that you may not be able to use "DLL Lua Modules" in this way. I don't know details. Try various cases. Best, Akira

frac font feature doesn't work as expected

\starttext \font\test={file:linlibertine_r.otf:+frac} \test 1/2 3/4 5/6 7/8 9/10 11/12 31415/27182 1000/1000000 \stoptext gives as output ½ 3¾ 5⅚ 7⅜ 9/10 1⅟12 31415/27182 1000/1000000 (I couldn't build an example without the primitive command. After \definefontfeature[frac][frac=yes] \definefontfamily[default][rm][linuslibertineo][features=frac] context always falls back to latin modern) A similar plaintex example for xetex \font\test="[linlibertine_r.otf]:+frac" \test 1/2 3/4 5/6 7/8 9/10 11/12 31415/27182 1000/1000000 \bye gives the correct result: ¹⁄₂ ³⁄₄ ⁵⁄₆ ⁷⁄₈ ⁹⁄₁₀ ¹¹⁄₁₂ ³¹⁴¹⁵⁄₂₇₁₈₂ ¹⁰⁰⁰⁄₁₀₀₀₀₀₀ A plain tex example for luatex is broken too but differently to the context version, one gets at least the correct numbers: \input luaotfload.sty \font\test={file:linlibertine_r.otf:+frac} \test 1/2 3/4 5/6 7/8 9/10 11/12 31415/27182 1000/1000000 \bye ½ ¾ ⅚ ⅞ 9/10 1⅟12 31415/27182 1000/1000000 -- Ulrike Fischer http://www.troubleshooting-tex.de/

Strange behaviour with spacing in itemization using "columns" vs "horizontal".
by cryo shock 05 Apr '17

05 Apr '17

Hi folks, I noticed a difference in how spacing is set after an itemization. I have the following example: ----------------------------- \starttext \startitemize[packed, joinedup, columns, two] \startitem top left item \stopitem \startitem bottom left item \stopitem \startitem top right item \stopitem \startitem bottom right item \stopitem \stopitemize Notice the size of the blank space? \startitemize[packed, joinedup, horizontal, two] \startitem top left item \stopitem \startitem top right item \stopitem \startitem bottom left item \stopitem \startitem bottom right item \stopitem \stopitemize Notice the size of the blank space? \stoptext --------------------------------- Both itemizations are the same except item order and using "columns" in the first one and "horizontal" in the second. Yet the spacing after the first itemization seems not right. Or do I oversee something? Greetings, Sebastian

float pages again
by Florian Grammel 05 Apr '17

05 Apr '17

Back in 2007 there was a discussion here on the list about whether context could do something like LaTeX’s float pages. http://www.mail-archive.com/search?l=ntg-context%40ntg.nl&q=subject%3A%22%5… In short these are designated pages that LeTeX puts in to collect abundant top- and here-floats. There can -- in contrast to contex’s default=page -- be more than one float on such a page and there is no running text. In a LaTeX-setup correcponding to: %\setupfloats[nlines=15] \setupfloat[figure][default={here,top,bottom,page}] \starttext \section{First Section} \input zapf \placefigure {Blah} {\externalfigure[figurename][width=5.0in, height=3.0in]} \placefigure {Blah} {\externalfigure[figurename][width=5.0in, height=3.5in]} \placefigure {Blah} {\externalfigure[figurename][width=5.0in, height=3.5in]} \placefigure {Blah} {\externalfigure[figurename][width=5.0in, height=3.3in]} \placefigure {Blah} {\externalfigure[figurename][width=5.0in, height=3.3in]} \section{Second Section} \input zapf \input zapf \input zapf \stoptext pages 2 and 3 wouldn’t have body text on them. Is there a possibility to have context remove body text from pages with floats when the space falls short of a certain number of lines? Hans mentioned nlines in the old thread, but commenting it in doesn’t seem to have any effect. Best regards, Florian. ____________________________________________ Florian Grammel Copenhagen, Denmark

underbar and overbar
by Henning Hraban Ramm 04 Apr '17

04 Apr '17

Ahoi, I played with the "bar" commands: \underbar{underlined \underbar{more and \underbar{more} \overbar{\underbar{and} \overbar{over}} and back}} While stacking bars is nice, overbar and underbar exclude each other, while underbar takes precedence. Is this intended? I expected different results. Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD

Presentations
by Mathias Schickel 04 Apr '17

04 Apr '17

Dear ConTeXt users, me again. I tried to send this emails before, but it seemed to be blocked, because I attached a sample file that seemed too big. This time I have a question concerning presentations. I was not able to figure out how I can define presentation steps in a way that each step is shipped as a single PDF page in the output. By this I mean steps in one slide that unfold step by step by moving on to the next pdf page. (This means one slide is represented in the PDF as a whole bunch of pages.) The command \StartSetps and \FlushStep does something like that, but this seems to use some JAVA script magic that only works using Adobe Acrobat (and the steps are unfolded by hitting the mouse button and not by going on to the next PDF page). How can it be modified in a way that a new page per step is created containing the next step in a way that going to the next pdf page unfolds the next step? You can get an example using (code out of the file present-stepper-001.tex out of the distribution) \usemodule[present-stepper] \starttext \Topic{Female Artists} \StartSteps \startitemize \item Fiona Apple \FlushStep \item Tori Amos \FlushStep \item Kate Bush \FlushStep \item Heather Nova \FlushStep \item Alanis Morissette \FlushStep \item Suzanne Vega \FlushStep \stopitemize \StopSteps \stoptext I really like the step solution ConTeXt uses but it would be nice to be able to switch between the (supposed) JAVA script solution and the presentation of a the steps of a slide as several pages. Besides that, it would be nice, too, to be able to configure the step mechanism in a way that the arrow keys of the keyboard unfold the next step (instead of hitting the mouse button). Is there any possibility to do that (if it would be, I would in deed prefer the ConTeXt approach to steps before the LaTeX one with several pages per slide). Apart from that, I have noticed that viewing the steps the first time disables them if you go back in the presentation. This means there is no way to go back that preserves the steps as such (or I was not able to found that way :-) ). (Especially it does not seem to be able to go back one step.) It would be more intuitive if going forward and backward followed the same steps. Another way to achieve something like that would be a reset button for each page that resets the step behaviour after having viewed the slide and it steps for the first time (in a way that for second viewing the steps mechanism could be reset). Apart form that the beamer package of LaTeX knows some commands like \only<[number of slide]>{<content>} that places the content in the brackets {} on the slide only at slide number [number of slide]. Does ConTeXt have a command like that? Thank you for your assistance! Kind regards Mathias Schickel

bug in index sorting with latest beta?
by Pablo Rodriguez 03 Apr '17

03 Apr '17

Dear list, I have this minimal sample: \mainlanguage[fr] \setupregister[method=default] \starttext Aristote\index{Aristote}, %~ Œdipe\index{Œdipe} Platon\index{Platon} d'Ænésidème\index{Ænésidème} \placeindex \stoptext If I comment the “Platon” entry, a is only one head. But if I compile with that entry uncommented using latest beta from 2017.04.02 19:51, a are two heads. Isn’t it a bug in index sorting? Many thanks for your help, Pablo -- http://www.ousia.tk

Textbackground issue with margin pictures
by Tom 03 Apr '17

03 Apr '17

Hi, today I updated from ConTeXt 2015.11.19 to the recent Beta 2017.03.26 16:15. I noticed that my textbackgrounds now interfere with margin pictures, that is, if there is a margin picture at the side of a textbackground, then the textbackground is suppressed for the entire height of the margin picture. Here is a minimal: \setuplayout [ leftmargin=0mm, rightmargin=45mm, height=fit, width=fit, ] \definetextbackground [test] \starttext \placefigure [margin]{}{} \starttextbackground [test] \dorecurse{3}{\readfile{ward}{}{}} \stoptextbackground \stoptext With the ConTeXt Current from 2016.05.19 13:43 I don’t see the issue, everything’s fine there. Here are two screenshots: Desired behavior (Ctx Current): http://d.pr/i/Xgtc Non-desired behavior (Ctx Beta): http://d.pr/i/1gyi Is this a bug? Thanks for any help. -- Thomas Floeren
