Keeping titles together with the following text when grid is on
by Jan Tosovsky 30 Nov '13

30 Nov '13

Dear All, when grid is on, orphan and widows have to be eliminated using additional penalty settings. Whereas it works fine for body text, section titles are still sometimes left at the bottom of the page. It can be reproduced using this example: \setuppapersize[B5] \startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{2}{10000} \setpenalties\clubpenalties {2}{10000} \stopsetups %comment the following line to see the difference \setuplayout[grid=yes, setups=mypenalties] \showgrid \starttext \blank[force, 9.5cm] \input tufte \section{Tufte} \input tufte \stoptext Is there any extra option for handling this? Thanks, Jan

Duplexing a single-sided layout?
by Adam Khan 30 Nov '13

30 Nov '13

I have a document in which left and right cannot be equated with inner and outer respectively (outside the header texts). So I use \setuppagenumbering[alternative={singlesided,doublesided}]. But I still need a gutter along (what would be) the inner margin. So, how would I go about duplexing a single-sided layout? For example: \definepapersize[custom][width=335mm,height=500mm] \setuppapersize[custom][B3] \setuplayout[% width=middle,% height=middle,% backspace=90mm,% topspace=25mm,% leftmargin=30mm,% rightmargin=15mm,% leftmargindistance=5mm,% rightmargindistance=20mm,% location={doublesided,duplex},% bottomspace=25mm,% cutspace=90mm] \setuppagenumbering[alternative={singlesided,doublesided}] Sincerely yours, Adam Khan

[***SPAM***] Provide showgrid as a PDF layer
by Jan Tosovsky 29 Nov '13

29 Nov '13

Dear All, it would be nice to have a possibility to interactively disable/enable a grid rendered via \showgrid command. Whereas this grid is helpful for debugging, it disturbs when the page is evaluated as the whole. Using layers could make this process more efficient (not requiring to generate both variants). I've noticed something like this is already implemented for the body area (visualizer vbox layer). Or is there any option for this already? Thanks, Jan

bibliography - maybeyear
by Alan Braslau 29 Nov '13

29 Nov '13

Hello, Using \setuppublications [alternative=num] for example, should not append letters to the publication years when encountering multiple publications by the same author(s) per year. So, in the use of bibliographies, I have not understood how to control \maybeyear. In the bibl-xxx.tex files, it is defined as \def\maybeyear#1{#1} or \def\maybeyear#1{} as needed. Perhaps this is for mkii. In bibl-bib.mkiv, one has \appendtoks \doifelse{\bibtexpublicationsparameter\c!maybeyear}\v!off {\let\maybeyear\gobbleoneargument} {\let\maybeyear\firstofoneargument}% \to \everysetupbibtexlistplacement which seems to then use the keyword maybeyear. I guess that \setupbibtexpublications [maybeyear=off] in my source would turn off the appended letters, but this is not correct. I have tried many variants (\setuppublications, \setupbibtex). What am I misunderstanding? Or is this a bug? Alan

sagemath in context (like sagetex)
by Xan 29 Nov '13

29 Nov '13

Hi, Is there any kind of package for embedded sagemath in ConTeXt (like sagetex in latex). I found the same question previosly asked (http://www.ntg.nl/pipermail/ntg-context/2009/040483.html) but more things are changed until 2009... so perhaps there is now a solution By the other hand, I see lua lunatic code: http://wiki.contextgarden.net/User:Luigi.scarso/luatex_lunatic#SageMath but this is very programmer centric code, in my opinion. Is there any easy way to do that? I use MKIV Thanks, Xan.

Unexpected behaviour of enumeration in mkiv
by Thomas Möbius 28 Nov '13

28 Nov '13

Hi, please have a look at the minimal example at the bottom. I am typesetting theorems and lemmata which are numbered consecutively within chapters in a book. I used the same code for a document written in mkii, and I thought I could just reuse it in mkiv. Obviously, there is something I am missing. Question: How do I get the same output when compiling the following code with 'context' as when compiled with 'texexec'. When compiled with 'context', the chapter number is missing in the numbering of theorems. Lemmas are not numbered at all. ~~~snip~~~ \setupenumerations [title=yes, style=normal, list=all, before={\blank[big]}, after={\blank[big]}, location=serried, width=broad, distance=0.5em, headstyle=bold, titlestyle=bold, way=bychapter, conversion=numbers] \defineenumeration [theorem] [text=Theorem, listtext={Theorem }] \defineenumeration [lemma] [text=Lemma, listtext={Lemma }, number=theorem] \starttext \chapter{First chapter} \theorem Hello \theorem Hello \lemma Hello \theorem Hello \stoptext ~~~snip~~~

Line numbers and tabulate cells in Mark IV
by Adam Khan 28 Nov '13

28 Nov '13

The lines of a tabulate cell may be numbered with code like the following under Mark II, but not under Mark IV. \starttabulate[|p|p|] \NC \input knuth \NC \startlinenumbering \input knuth \stoplinenumbering \NC\NR \stoptabulate How may the lines of a tabulate cell be numbered under Mark IV? Sincerely yours, Adam Khan
