Wrapping \type{}
by Nikolai Weibull 02 Dec '04

02 Dec '04

In my BNF module I use " as an active character that begins and ends terminals in the grammar: <regex>: <branch> ; <branch>, "\|", <regex>. Now, the above doesn't quite work as written, as \ is still active (and so is, in fact | as we're really inside a \starttabulate. What I would like for the "" pair to do is work as a wrapper for \type{}, so that everything in-between is passed on to \type{}. Is there a way of getting them to do that? This is my current definition: \gdef"% {\ifBNFoutsidestring% \global\BNFoutsidestringfalse% \begingroup% \BNFunsetcatcodes% \catcode`\"\@@active% \@@bnfterminalstart% \else% \@@bnfterminalstop% \endgroup% \global\BNFoutsidestringtrue% \fi} I figured something like \long\gdef"#1"% {\type{#1}} might work, but it didn't. It chokes on "." where . is also an activated character for terminating a production in the grammar. Any suggestions on how to go about this? I mean, the obvious solution is simply to write <regex>: <branch> ; <branch>, "\type{\|}", <regex>. instead, but I would like to keep the input as clean as possible. nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

\setupURL issues
by Nikolai Weibull 19 Nov '04

19 Nov '04

\setupURL [color=blue] seems buggy. Try this: \setupcolors [state=start] \setupinteraction [state=start] \setupurl [color=blue] \useURL[one][http://www.google.com/] \starttext Why the hell is \from[one] wrapping so badly? \stoptext You will (hopefully...or something) notice that the http:// appears above and slightly to the left of www.google.com in the sentence. remove \setupurl[...] and it works fine, rendering it green. It also works fine if you remove the color=blue and add style=type instead or whatever. In noninteractive versions this works fine though and in documents without \setupcolors[state=start], nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

Table question
by Thomas A.Schmitz 15 Nov '04

15 Nov '04

Hi all, quick question: does any of the table environments in ConTeXt (table, tables, TABLE, linetable) provide the possibility to have double lines separate some rows and columns? A || B | C __________ ---------- D | E | F Thanks a lot! Thomas

Losing frames in table
by David Arnold 03 Nov '04

03 Nov '04

All, How come I don't get frames (rightframe=on, bottomframe=on) in my table with this? \setupTABLE[background=screen,screen=0.8,color=darkred,frame=off] \setupTABLE[column][first][rightframe=on] \setupTABLE[row][first][bottomframe=on] \placetable[none]{}{% \bTABLE[align={middle,lohi},width=3em] \bTR \bTD $x$ \eTD \bTD $y$ \eTD \eTR \bTR \bTD $x_1$ \eTD \bTD $y_1$ \eTD \eTR \bTR \bTD $x_2$ \eTD \bTD $y_2$ \eTD \eTR \bTR \bTD $\vdots$ \eTD \bTD $\vdots$ \eTD \eTR \bTR \bTD $x_n$ \eTD \bTD $y_n$ \eTD \eTR \eTABLE}

three questions on footnotes
by Steffen Wolfrum 02 Nov '04

02 Nov '04

Hi, as beautiful footnote placement is one of the most brilliant features in TeX I were happy if these three detail questions could also be answered with ConTeXt. Hans, do you have some time left to have a look, please? As always, thank you very much, Steffen -> 1. headcommand How do I use this new command for moving my footnotemarker? I found only "location=top" showing a result and that was quite stupid ... \setupfootnotedefinition[location=command,headcommand=\llap] -> 2. footnotes (short: behind, long: below)? Is there a predefined command for placing short footnotes at the bottom of each page but horizontally continuos? Is saw this way of typesetting footnotes in a book I've read. It looks likes this: body text body text body text body text body bo- dy text body text body. ------ 1 short 2 short 3 short 4 short 5 but hey: the long note starts in a new line! I have never seen footnotes like this before. But it reads very pleasant: This way you don't have lot of empty white space (because of short notes), and it still is very clear (for the long footnote starts on a new line). Is it possible to typeset this in ConTeXt? -> 3. Footnotes in margin? Hans once posted the code listed below. But the result on longer footnotes were halfempty (body text) pages. Is there a bug fix, a work around? > >does ConTeXt provide a way to place footnote (not margin notes!) per page - but not below the body text? > >A suitable place could be the margin.

Getting linuxtex.zip working
by Nikolai Weibull 02 Nov '04

02 Nov '04

Exactly what do I need to do after running setuptex, mktexlsr, and texexec --make --alone? PATH needs permanent updating for sure, but what else? texexec won't work (kpsewhich won't work) unless setuptex is sourced before I try running it in a fresh shell. What am I missing in my setup? nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

precompiling inline mp to pdf?
by Christopher Creutzig 02 Nov '04

02 Nov '04

Salvete, for my latest project (almost done, so I don't need the answer for this one, but possibly in the future) I have compilation times which were dominated by Metapost until I switched to using --nomp most of the time and --automp --runs=2 whenever I changed something that results in changes to the Metapost stuff. (I needed the --automp anyway, since to work around size limits in MetaPost I had to split the background into separate images, yet they had to influence one another via global variables -- increasing the memory limit to 80 MB made Metapost predictably freeze at unpredictable places in the run.) Now, my compile times are dominated by the mp to pdf conversion. Since pdf inclusion is fast (as expected), I'd like to use mptopdf once on each generated file and have ConTeXt include that. Should I redefine \insertMPfile to first look for the pdf or is there a more clever way? (Note that I do want the automatic inclusion, since I'm passing the dimensions of external figures etc. to metapost and use the result in a background layer and/or as frame backgrounds.) regards, Christopher Creutzig PS: I didn't have time to analyze this when I came across it, but it seems that "texexec --automp file" consistently performs one TeX run too little. In any case, the last thing it does is a metapost run, which doesn't seem sensible to me.

minimal ConTeXt tree
by Steffen Wolfrum 01 Nov '04

01 Nov '04

Hi all, I wanted to give my TeX a fresh start, deleted the complete tetex folder and downloaded Hans' "macosxtex.zip". Could someone please share his/her experience what to do now - in order to get the files in this zip work? I am working on MacOSX and - by now - I am not so firm on the path topic that's probably necessary now... so I need probably a *very easy explanation* :o/ Any help welcome! Steffen

Re: subsubsubsection
by Steffen Wolfrum 31 Oct '04

31 Oct '04

... sure I have seen that subsubsubsection is already defined in core-sec.tex. Then the numbering/charactering works fine ... BUT why does a heading that's mapped to it just not appear in the TOC? Steffen

side-by-side
by David Arnold 31 Oct '04

31 Oct '04

All, I have: \page \subject{Plotting} With preliminaries completed, plotting is a simple matter. \starttyping >> x=linspace(-2,4); >> y=x.^2-2*x-3; >> plot(x,y) >> xlabel('x') >> ylabel('y') >> title('y = x^2 -2x -3') >> grid on \stoptyping \placefigure[none]{}{\externalfigure[slide1.png]} I'd like to arrange this on my slide side-by-side, the code to the left, the image to the right. If I we're doing this in Latex, I would probably use minipage environments for this. Can someone hint at the Context Way of doing this? I'd like my code vertically centered on the left, the image on the right. Thanks.
