Stepper code fails
by Michael Guravage 28 Mar '14

28 Mar '14

The Stepper example on the wiki, <http://wiki.contextgarden.net/Stepper>from which the following snippet comes, \usemodule[pre-60] % use the stepper \setuppapersize[S6][S6] \defineoverlay[invoke] [\overlaybutton{InvokeStepper}] \setupbackgrounds[text] [background=invoke] \setupinteraction[state=start,click=off] \starttext ex nihilo \stoptext fails here with the following error: ! LuaTeX error ...eXt-beta/tex/texmf-context/tex/context/base/lpdf-mis.lua:146: attempt to call upvalue 'pdfaction' (a nil value) stack traceback: ...eXt-beta/tex/texmf-context/tex/context/base/lpdf-mis.lua:146: in function '?' ...eXt-beta/tex/texmf-context/tex/context/base/lpdf-ini.lua:700: in function 'run' ...eXt-beta/tex/texmf-context/tex/context/base/lpdf-ini.lua:722: in function 'finalizepage' [string "\latelua "]:1: in main chunk. Though I am using the latest beta, I do not think this problem caused by changes in the latest release. I have attached the log file for those who are interested. Any suggestions how to rectify this problem would be much appreciated. With kind regards, Michael Guravage

Box flowed and hanging into the margin
by Markus Finke 28 Mar '14

28 Mar '14

I need a textbox with an opening and closing picture as border. This box should be flowed around by maintext and hanging into the outer margin (for reasons of space and design). It seems to be a simple task but I have no advance since days. Any idea? \setuphanging[location=right] \starttext \starthanging{ \placefigure[here,none]{} {\startcombination[1*2] {\externalfigure[line.png][width=5cm]}{\tfx\input ward \endgraf} {\externalfigure[line.png][width=5cm]}{} \stopcombination} }\input knuth \stophanging \stoptext

tweaking placefloat
by Henning Hraban Ramm 27 Mar '14

27 Mar '14

Hi wizards, in a new book project I need to place some photos covering the upper or lower half of the page (bleeding, not within textarea) with a caption below resp. above the photo, within textwidth. Is it possible to tweak placefloat, so that I can use \placefloat[here,top/bottom]{Caption}{\externalfigure[something][width=\the\dimexpr\paperwidth+3mm\relax]} for this layout? Or is there a better solution? Should I use layers instead? Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

quick and shallow question about layers
by Schmitz Thomas A. 26 Mar '14

26 Mar '14

Hi, this is pretty shallow, but maybe someone knows a way: for one of my presentation, every slide has a (different) picture as background. The title is typeset within a narrow colored frame which extends across the entire slide. Is there any way to make the background picture show through the letters of the title, i.e. make the letters transparent within the colored frame? I thought of metapost’s infill, but it appears that this only adds a background color, not real transparency. Hope the question is clear enough - just in case someone has a suggestion; my life doesn’t depend on it! Thanks and all best Thomas

extra link border with alternative=c
by Pablo Rodriguez 26 Mar '14

26 Mar '14

Hans, I have a the following sample: \setupinteraction[state=start] \enabledirectives[references.border] \setuplist[chapter][alternative=d] \starttext \completecontent \chapter{\TeX} \stoptext It shows that the E from \TeX has an extra frame in content list. I don’t know what might be causing it, but it seems to be wrong. Many thanks for your help, Pablo -- http://www.ousia.tk

Footnote maker in parentheses
by Stéphane Goujet 25 Mar '14

25 Mar '14

Hello, I would like that the footnote marker (both in the note call and the footnote text) appear in parentheses. I tried using : \setupnotation[footnote][titleleft={(},titleright={)}] because the names title* sounded close to what I was looking for, but it did not produce any change (neither in the call nor in the foonote itself). Are those the correct parameters to play with ? Do they need another parameter/option to be set in order to enable them ? Greetings, Stéphane.

Color of the "headers" of one enumeration
by Xan 25 Mar '14

25 Mar '14

Hi, I have this \defineenumeration [punt] [alternative=serried,text={\startcolor[darkblue]Punt\stopcolor},stopper={.\space},left={\bgroup},right={\egroup},width=fit,headstyle=\ss,distance=0.25em,width=fit] So I get "Punt 1. bla,..." How can I achieve that "Punt 1." were in darkblue? Now I just have "Punt". Thanks in advance, Xan
