Titles numbering
by Michał Goliński 17 Feb '16

17 Feb '16

The following file used to give me numbered titles (and still gives numbered titles in TeXLive): \setuphead[part][ placehead=yes, page=yes, % number=yes ] \setuphead[chapter][ page=yes, % number=yes ] \starttext \startpart[title={Part one}] \startchapter[title={Fancy chapter name}] \startsection[title={A very very very long section title}, list={Shortened somewhat}] \input knuth \stopsection \stopchapter \stoppart \startbackmatter \startchapter[title={Contents}] \placecontent[criterium=all] \stopchapter \stopbackmatter \stoptext In the current beta, they are unnumbered. Has the syntax changed? Besides, according to wiki, "number=yes" should force a numbered title, while uncommenting these lines in fact suppresses the number in TeXLive (and does not help in beta). Is this a bug/work in progress or am I doing something wrong here? Regards Michał

new error in Context-Metapost
by Meer, Hans van der 17 Feb '16

17 Feb '16

Some code that worked ok but hasn't been used for some time, now gives an error: missing $. It is working fine in ConTeXt, but putting it inside an MPpage goes wrong. Here a minimal example, the output of the ConTeXt run and the error on the MPpage run. Has something changed I missed? Hans van der Meer The error occurs in this code, my suspect is the cases macro. \starttext \startsetups[dif-1] $\displaystyle \Delta_{in} = 1000_2 \cases{(A,2)(2,A)&\cr (6,E)(E,6)&\cr} \buildrel S_1 \over \rightarrow \quad \Delta_{uit} = 1011_2 \cases{(6,D)(D,6)&\cr (B,0)(0,B)&\cr} $ \stopsetups \startMPpage label("\setup[dif-1]",origin); \stopMPpage \stoptext tex error > tex error on line 9 in file /Users/hansm/Documents/TeX/Test-tex/cases/cases.tex: !

Absolute position in table cell
by Volker Mische 17 Feb '16

17 Feb '16

Hi all, I'd like to position some text in a corner of a natural table cell. I got as far as being able to put the same text on every cell (a "p" in the example). Now my problem is, how do I specify the contents of the overlay/layer on a per cell basis? Best for me would be if I could define the text directly within the cell. I'm surely open to a completely different solution that has the same outcome. Here's the minimal example of what I currently have. \starttext \definelayer [pagenumber][width=\overlaywidth,height=\overlayheight] \defineoverlay[pagenumber][{\directsetup{pagenumber}\tightlayer[pagenumber]}] \startsetups pagenumber \setlayerframed [pagenumber] [preset=rightbottom] {p} \stopsetups \bTABLE \setupTABLE[each][each][background=pagenumber] \bTR \bTD multiline \par text \eTD \bTD some cell \par with even \par more \par text \eTD \eTR \eTABLE \stoptext Cheers, Volker

horizontal list of sections/topics?
by Thomas A. Schmitz 16 Feb '16

16 Feb '16

Hi, this is a quick question before I start coding: for my next presentation style, I would like to have a list of topics with the current topic highlighted. There are already two styles in simpleslides doing this, but this time, I'd like the list to be horizontal, at the bottom of the slide. Is there already a listalternative for this? Or is it not too complex to have a \definelistalternative do this? Or would it be easier not to rely on the list mechanism but code something from scratch? Thanks for your advice and all best Thomas

Usedirectory and paths in OSX and Windows
by Jaroslav Hajtmar 15 Feb '16

15 Feb '16

Hello ConTeXist. I use standalone ConTeXt in both OS - Windows and Mac (OSX El Captain) together for my onedrive synchronized data. Can anyone advise me whether you can somehow arrange compatibility of paths to my libraries? For example the following: In windows I have: \usedirectory[c:/path/to/myown/library/directory/module/] \usemodule[mymodule] Where c:/ is root directory ... Is there possible put path into library in any "compatibility mode" of both OS? Is there any possibility define starting point of path? If the answer is trivial, than sorry. I note that I am a complete beginner MAC OSX and although I advanced user of Windows, then some basic things in OSX yet I reveal hardly. Thanx Jaroslav Hajtmar

Job done event
by Lukáš Procházka 15 Feb '16

15 Feb '16

Hello, during typesetting a document I'm collecting some information. At the end (i.e. right before \stoptext or right after \stoptext), I'd need to perform an operation. The way is to place some code before my code: \starttext ... \DoSomethingMine \stoptext But I'm looking for a way that the code inside document prepares the final operation and a way to avoid writing "\DoSomethingMine" before \stoptext (or \stopcomponent) - something being processed by ConTeXt naturally. Something like: \starttext ... \startluacode context.reactors.jobfinished = function(prev_op) -- Do something mine prev_op() end \stopluacode ... \stoptext % ConTeXt to call "context.reactors.jobfinished" or similar implicitly Does ConTeXt offer something like described? (Would be nice...) Best regards, Lukas -- Ing.

Character rotation font feature available?
by Zhichu Chen 14 Feb '16

14 Feb '16

Dear list, I have some special needs that requires all the characters be rotated by 90 degrees. I've searched around the web and maybe adding /FontMatrix [0 1 -1 0 0 0] to the font descriptor dictionary is helpful. But I can't find a \pdf??? primitive that can achieve this. (Am I wrong about this?) Another solution might be the "vrt2" font feature. There's no difference between the results with or without enabling the feature. But I do see the font has the feature by using the shell command: otfinfo -f <fontname.otf> May I put my temporary unsatisfying code here and ask for optimization?
