How to create horizontal line for signature?
by Paul Menzel 13 Dec '11

13 Dec '11

Dear ConTeXt folks, sometimes you need to insert a line for signature. I could not find anything usefull especially `\underbar{\hspace[10*\big]}` [2] did not work. I ended up abusing `\framed` [3]. \starttext \startstandardmakeup[align=right] Alles rechtens. Everything is fine and nobody cheated. \blank[medium] London, den 28.\,June 2011 \blank[3*big] \framed[width=5cm, frame=off, topframe=on]{\small John Doe} \stopstandardmakeup \stoptext The down side is, that its widths is not perfectly aligned with the location and date. I guess there is something simpler to do it. I looked at Wolfgang’s letter module but could not figure out how it is done there. Something like the examples posted for LaTeX on Stack Exchange [3] for ConTeXt would be nice.

gnuplot module: `option=monochrome` does not work.
by Paul Menzel 13 Dec '11

13 Dec '11

Dear ConTeXt folks, I want to create monochrome plots, but `option=monochrome` is ignored. \usemodule[gnuplot] \setupGNUPLOT[terminal=context,option=monochrome] \startGNUPLOTscript[pi] plot pi t '$π = \ctxlua{context(math.pi)}$' \stopGNUPLOTscript \starttext \useGNUPLOTgraphic[pi] \blank \CONTEXT\ \contextmark\ \contextversion \stoptext Is that the correct way to enable monochrome output? Looking at the Wiki page [1] it should be something like the above. Am I doing something wrong? Thanks, Paul [1] http://wiki.contextgarden.net/Gnuplot

Initials / DroppedCaps
by Henning Hraban Ramm 13 Dec '11

13 Dec '11

For a book of fairy tales, I used (working!): \def\Initial{\DroppedCaps% {\color[red]} {Serif} {2.5\baselineskip} {3pt} {2\baselineskip} {3}} \starttext \Initial Once upon a time... \input tufte \stoptext But that gives now: <to be read again> \unskip \\->\ifhmode \unskip \prewordbreak \crlfplaceholder \ifcase \raggedstatus \h... \somefontsize ->2.5\\ baselineskip \lowleveldefinefont ...aledfontsize \somefontsize \or \scaledfontsize \local... \dododefinefont ...inefont {#2}\rawfontidentifier \csname \rawfontidentifier... \dodefinedfont ...nedfont][#1]\fi \thedefinedfont \the \everydefinedfont ... l.7 \Initial O nce upon a time... \input tufte It works, if I use absolute values for font size and vertical offset, like \def\Initial{\DroppedCaps% {\color[red]} {Serif} {36pt} {3pt} {28pt} {3}} I also tried \setupinitial / \placeinitial like below; I got my defined font, but only ever in base font size. %\definefontsynonym[Initial][WieynkInitialen] \setupinitial[font=WieynkInitialen,n=3,state=start,command=\Initial] % I also tried \NiceDroppedCaps and \LineDroppedCaps that I found in the sources, but didn’t get further. So, what’s the preferred way to get dropped capitals / initials? I’d like to wikify that, since it seems nowhere documented. Greetlings from Lake Constance!

KOMA-srcartcl Type Area: How to count header and footer to text area?
by Paul Menzel 13 Dec '11

13 Dec '11

Dear ConTeXt folks, having heard nice things about the KOMA script type area I wanted to use it too and tried out the example in the Wiki [1]. % Set binding correction value (mode=BCOR turns it on). \doifmodeelse{BCOR}{\def\bindingcorr{3mm}}{\def\bindingcorr{0pt}} % Set visible page width. \newdimen\PageWidth \PageWidth=\dimexpr(\paperwidth-\bindingcorr) % Determine the paper aspect ratio. \edef\Ratio{\withoutpt{\the\dimexpr(2\paperheight/(\PageWidth/32768))}} % Set the textarea width to 2.6 alphabets. \setbox\scratchbox\hbox{\dorecurse{26}{\character\recurselevel}} \newdimen\Width \Width=\dimexpr(2.6\wd\scratchbox) % Set the textarea height proportional to the width. \newdimen\Height \Height=\dimexpr(\Ratio\Width) % Set the margin/gutter widths to be equal on a full spread. \newdimen\Back \doifmodeelse{oneside} {\Back=\dimexpr(((\PageWidth - \Width) / 2) + \bindingcorr)} {\Back=\dimexpr(((\PageWidth - \Width) / 3) + \bindingcorr)} % Set the top and bottom margins in a 1:2 ratio, ignoring headers. \edef\Top{\the\dimexpr((\paperheight - \Height) / 3 - 3\lineheight)} % Redefine \Height to include header and footer space. \Height=\dimexpr(\Height + 8\lineheight) % Set up the page layout using the calculated parameters. \setuplayout[ backspace=\the\Back, height=\the\Height, width=\the\Width, header=2\lineheight, headerdistance=\lineheight, footer=2\lineheight, footerdistance=3\lineheight, topspace=\Top] \starttext \framed[width=\textwidth,height=\textheight]{} \stoptext I only want to add a page number to the footer [3] and I do not want to use any header [2, and ConTeXt manual]. Therefore I set \setupheader[][state=none] \setuppagenumbering[alternative=doublesided, location={footer}] \enablemode[BCOR] According to the KOMA-Script manual [4] having just a page number in the footer it should be counted as belonging to the margin. The only way I found out to achieve that was setting `\footdistance=0`. Is that the “correct” way to comply with the KOMA-Script type area recommendation? Please find the adapted example attached. Thanks, Paul [1] http://wiki.contextgarden.net/KOMA-scrartcl_Type_Area [2] http://wiki.contextgarden.net/Layout [3] http://wiki.contextgarden.net/Reference/en/setuppagenumbering [4] ftp://ftp.dante.de/pub/tex/macros/latex/.../koma-script/scrguide.pdf

headers: numberconversion=something or \definestructureconversionset
by Philipp A. 13 Dec '11

13 Dec '11

hi list, i want to make an exercise sheet style. exercises are already correctly rendered as “*Exercise <1>: <Text>*”, but sub-exercises should simply be like “*<a>)*”. what i tried: \definestructureconversionset[ex][numbers,characters][numbers] \setupheads[numberconversion=ex] and \setuphead[subsection][numberconversion=characters, …] but i have no idea what i’m doing in the first case and even less idea of what i’m doing wrong in the second. documentation would help in both cases, but contextgarden just has some (for me) incomprehensible examples. thanks, philipp ------------------------------ what i’d really love to have is the following commands, but i’ll figure it out once i have above problem solved. “\sheet” reads the current sheet number from the file name and gives “*Sheet <1>*” as title level header. “\exercise[<descr>]” gives “*Exercise <1>*” without and “*Exercise <1>: <descr>*” as section level header. “\subexercise[<descr>]” gives “*<a>)*” without and “*<a>: <descr>)*” with description as subsection level header.

pdfselect and context command?
by Verhaag, G.C.H.M. 13 Dec '11

13 Dec '11

Hi ConTeXTt User's, I was looking for the --pdfselect option in the context-command, but it doesn't seem to be available. This option is available in texexec to select certain pages from a pdf file. Can it also be done in some way using the context-command? Regards, Gerard Verhaag

Lua and module gnuplot: Manipulate Gnuplot script with Lua
by Paul Menzel 13 Dec '11

13 Dec '11

Dear ConTeXt folks, I have two coefficients saved in a text file -0.157737135681261 -0.211443105668896 and I want to use them to plot a line with gnuplot. Having several of those files I want to use Lua to create the formula for the line for me. I have not yet figured out how to read values from a file in Lua and just tried to print a constant to the gnuplot command. I tried the following. \usemodule[gnuplot] \startGNUPLOTscript[lua] plot \ctxlua{context(1.2 * x + 3)} \stopGNUPLOTscript \startGNUPLOTscript[nolua] plot 1.2 * x + 3 \stopGNUPLOTscript \starttext \useGNUPLOTgraphic[lua] Above should be a plot. \useGNUPLOTgraphic[nolua] \blank \CONTEXT\ \contextmark\ \contextversion \stoptext But only the second plot done and for the first the following error is shown. mtxrun | mtxrun | executing: gnuplot gnup-gnuplot-1.plt mtxrun | mtxrun | plot \ctxlua{context(1.2 * x + 3)} ^ "gnup-gnuplot-1.tmp", line 1: invalid character \ Is there a way to manipulate gnuplot scripts with Lua? Thanks, Paul

Reverse numbering
by Otared Kavian 13 Dec '11

13 Dec '11

Hi all, When using \startitemize[n,reverse] one gets items numbered in reverse order. I wonder if this feature exists also for enumerations. An example is given below in which the last enumeration is written on top of the file and I wish it were possible to have the enumerations numbered in reverse order. Thanks in advance for any insight: OK PS: here is an example file: %%%% enumeration-reverse.tex \defineenumeration[Lecture] [location=hanging, text={Lecture n°}, between=, before=, stopper={.}, after= {\hrule\blank}] \setupenumerations[Lecture][number=yes] % \setupenumerations[Lecture][numbering=reverse] % this has no effect though… \starttext \startLecture Tuesday December 6th: Banach spaces. \startitemize[n] \item First subject. \item Second subject. \stopitemize \stopLecture \startLecture Tuesday November 29th: Norms. \startitemize[n] \item First subject. \item Second subject. \stopitemize \stopLecture \startLecture Tuesday November 22nd: Topological Vector Spaces. \startitemize[n] \item First subject. \item Second subject. \stopitemize \stopLecture \stoptext %%% end enumeration-reverse.tex
