All, Has anyone done any coding with the marith.mp package of Metapost? Any code that you can share? My specific task is to draw the polynomial x^3-7*x^2+7*x+15 on the domain [-50,50]. Thanks.

some small questions
by Peter Münster 07 Jan '06

07 Jan '06

Hello, here comes a repost of some still unsolved (at least for me) questions: - What is the best way, to get never the serif version of the euro, only the sans? Test file: \usemodule[symb-eur] \useregime[il9] \enableregime[il9] \starttext bla € bla \stoptext - What is the right syntax to get "hz,normal" ? I tried \setupfonthandling[highquality] and \setupalign[hanging,hz] but these two commands don't seem to change anything. Test file: \starttext \input tufte \setupfonthandling[highquality] \setupalign[hanging,hz] \input tufte \stoptext TIA for any help! Cheers, Peter -- http://pmrb.free.fr/contact/

Bibliography problems
by David Antos 07 Jan '06

07 Jan '06

Hello, I have several problems with the bibliography module in last stable (2005.12.19). You can find a minimal (well, as minimal as I was able to prepare ;) example at http://www.fi.muni.cz/~xantos/biblio-example.tgz . First, starting with the second page of bibliography, the beginnings of lines are not aligned to the left. Moreover, some entries produce an empty line after them. It seems probable that some unwanted spaces appear in the macros. In "misc" entries, only authors and titles are typeset. See the very first entry cited in the document (Ha\v{z}muk): it contains howpublished and month and they are ignored. BTW, is the \cite inside the bibliography entry likely to work? Can I correct my setups somehow to override those problems? Thanks a lot, D.A. -- I have never let my schooling interfere with my education. -- Mark Twain

paragraph indenting
by Christopher G D Tipper 06 Jan '06

06 Jan '06

Hi, I hope this is not a bug, and that the reference manual is just incorrect. In This is pdfeTeX, Version 3.141592-1.30.4-2.2 (Web2C 7.5.5) (format=cont-en 2005.12.24) 6 JAN 2006 20:07 ConTeXt ver: 2005.12.19 fmt: 2005.12.24 int: english mes: english The following produces no indenting at all. I expect all paragraphs to be indented except for the very first. \starttext \setupindenting[small] \noindenting\input knuth \input knuth \stoptext Some of my very old stylesheets stopped working when I moved to a new machine. What is the new syntax, please?

colors in MPgraphic
by Hans van der Meer 06 Jan '06

06 Jan '06

In MPgrapic I do want my own colors for drawing lines etc. These are set up in plain.mf's ("_op_" and "background"). In \startMPinclusions I just do that in order to get the drawing color I want. But then \startMPgraphic appears to reset colors (both "_op_" and "background" I suspect). Can this be changed? In plain.mf there is already a setup, so there seems no reason for \startMPgraphic to interfere. It would be nice if the color setup done in \startMPinclusions would be honored. It is a nuisance to have them set up in a special initalization file and then being forced to repeat this at the start of every graphic. Question: what tinkering with metapost parameters is done in \startMPgraphic exactly? (I could not find out readily from the ConTeXt sources) Which of these can be removed without danger for its operation, leaving settings in \startMPinclusions unchanged -- and will that be done? yours sincerely, dr. H. van der Meer

Thank you very much! Actually, in the real environment I needed the \expanded at another place: \def\Sender#1#2#3{\setvalue{SenderKey#1}{#2}\setvalue{SenderVal#1}{#3}} \def\GetSenderLine#1{\bTR\bTD\doiftextelse{\getvalue{SenderKey#1}} {\getvalue{SenderKey#1}:}{}\eTD\bTD\getvalue{SenderVal#1}\eTD\eTR} % initialize values (not even needed) \dostepwiserecurse{1}{9}{1}{ \Sender{\recurselevel}{}{} } \startsetups sendertablesetup \setupTABLE[frame=off] \setupTABLE[x][1][width=\senderkeywidth, align=left, style={\keystyle \strut}] \setupTABLE[x][2][width=\sendervalwidth, align=right, style= {\valstyle\strut}] \bTABLE \dostepwiserecurse{1}{9}{1}{% count from 1 to 9, step 1 \expanded{\GetSenderLine{\recurselevel}} } \eTABLE \stopsetups I collect this (and more) at http://wiki.contextgarden.net/ Talk:Letter_style Grüßlis vom Hraban! --- http://www.fiee.net/texnique/ http://contextgarden.net http://www.cacert.org (I'm an assurer)

problem with \startlanguagespecifics
by Peter Münster 06 Jan '06

06 Jan '06

Hello, I get: ERROR: TeX capacity exceeded, sorry [input stack size=1500]. --- TeX said --- \@@la@ec@-en@@la ->\@@la@ec@-en@@la \def \Fuco {fff} and so on... with the following input file: \mainlanguage[de] \def\Fuco{FFF} \startlanguagespecifics[en] \def\Fuco{fff} \stoplanguagespecifics \starttext \Fuco {\language[en] \Fuco} \Fuco \stoptext but very strange: when I exchange "de" and "en" (en <-> de), then it works well.

When I put a \cite inside buffer and that I \getbuffer inside the text, the reference displys correctly BUT the list of reference isn't anymore displayed.(I use Bibtex) I have the latest bibmodule (11.23.2005) Is that a bug ? Hos to avoid this behaviour ? (I'm a beginner). Thanks
