Data into arrays in Metapost
by David Arnold 12 Aug '05

Hi, Is there a way to read an entire data set into an array in Metpost, something like: numeric coeffs[]; coeffs:=[1,2,3,4,5];

\starttabulate vertical spacing
by Christoph Czarnetzki 11 Aug '05

11 Aug '05

Hello! i want to put some space between lines in a tabulate environment. \starttext \starttabulate[|l|p(1cm)|] \NC Some Text \NC Other Text \NC\NR\HL \NC Some Text \NC Other Text \crlf\NC\NR \NC Some Text \NC Other Text \NC \stoptabulate \stoptext i did it with \crlf, but this is too much for me. \godown doesnt work either. Half of a line in space would be great. I tried that with starttable too, but the \HL command in tabulate works better. The text is aligned directly under the ends of the line. So i use tabulate. And the other problem is, crlf only works if tab is set to |p|. thanks! Christoph

MPcolor problem (CMYK)
by Jin-Hwan Cho 11 Aug '05

11 Aug '05

In the MetaFun manual (metafun-p.pdf) p.117, you may see an example using the color ".5\MPcolor{cmyyellow}". But I could not generate the color. Could anyone check the attached sample?

\Shaped macro in MetaFun manual
by Jin-Hwan Cho 11 Aug '05

11 Aug '05

The third line in the page 145 in the MetaFun manual (metafun-p.pdf) says The \Shaped macro was defined as: .... some \inframed[background=Shape]{text} with a frame ... .... some \Shaped{text} with a frame ... It seems to be a typo. Let me know the exact definition of \Shaped macro. Thanks in advance.

Clipping a path to a boundary --- Being more specific
by David Arnold 10 Aug '05

10 Aug '05

Hans et al, Let me try to be more specific. Here is a file which is very typical of the way I draw graphs for my mathematics classes. When you compile, you will see the graph of the absolute value of x-1. That is, it draws the graph of y=|x-1|, but only after clipping it to the cpath. What I would like to do is draw the graph with the drawdblarrow command so that the graph of the absolute value ends in arrowheads. So, I want to clip the graph to the bounding box, save the picture, null the picture, then somehow extract the path into the variable F in its clipped form (not the original path F that extends outside the clip path) so that I can replace the command draw pic with drawdblarrow F. beginfig(0); numeric a, c; a=1; % define function f(x)=|x-a| vardef f(expr x)= abs(x-a) enddef; % draw line with given point and slope path F; F:=(-5,f(-5)); for x=-5 step 1 until 5: F:=F--(x,f(x)); endfor; % initialize scale numeric u; 10u=3in; % the line F:=F scaled 1u; draw F withcolor blue; % clipping path path cpath; cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle; cpath:=cpath scaled 1u; % clip and save current picture picture pic; clip currentpicture to cpath; pic:=currentpicture; currentpicture:=nullpicture; % erase currentpicture currentpicture:=nullpicture; % draw grid for k=-5u step 1u until 5u: draw (-5u,k)--(5u,k) withcolor 0.85white; draw (k,-5u)--(k,5u) withcolor 0.85white; endfor; % draw axes drawarrow (-5u,0)--(5u,0); drawarrow (0,-5u)--(0,5u); % label axes label.rt(btex $x$ etex, (5.2u,0)); label.top(btex $y$ etex, (0,5.2.u)); label.bot(btex $5$ etex, (5u,0)); label.lft(btex $5$ etex, (0,5u)); % redraw line draw pic; endfig; end.

Mail troubles
by Taco Hoekwater 10 Aug '05

10 Aug '05

Hi, I just want to let everybody know that I am experiencing problems with email delivery since monday morning around 8 a.m. Hopefully, everything should return to normal during the day. I'm writing this because chances are that I've missed some mail addressed to me, esp. private off-list email. If you expect me to answer to something you sent, it is probably wisest to re-send it. Greetings, Taco

List head colour
by Duncan Hothersall 10 Aug '05

10 Aug '05

Quick question. With "\startitemize[n][color=red]", "\item ..." gives me the item number in red, but "\head ..." gives me the item number in the default colour. With "\startitemize[n][headcolor=red]", "\head ..." gives me the whole line in red including the number. Is there any setup which can give me just the item number in red when using "\head ..."? Is it possible? Thanks all. Duncan

Using latex font-packages
by Kai Militzer 09 Aug '05

09 Aug '05

Hello list, I am trying to use latex fonts (to be more precize: the allrunes font) downloaded from the ctan-ftp-Server and installed correctly in my texmf-tree, in context, but I now realise that it does not work as easy as I expected (i.e. just using the latex-commands). If anyone could help me or point me in the right direction how to do it, I would be very thankful, as I have a deadline at the end of the week at which it has to work ;) Best regards Kai

\placelist disturbs grid?
by Vit Zyka 09 Aug '05

09 Aug '05

Hello Hans, Taco, and the next gurus, sorry for bother with another thing I can not understand. Very high glyphs like \v S disturb grid in the \placelist. The same glyph in the common paragraph with the same (intentionally) interline setting preserves grid: --------------------------------------- \setupbodyfont[10pt,rm] \setupinterlinespace[line=12pt] \setuplayout[grid=yes,width=8cm] \showgrid \writetolist[section]{}{See the next line:} \writetolist[section]{}{\v Sejba} \writetolist[section]{}{Another list line} \starttext \v Sejba\par Here grid is OK, but in \type{placelist}: \placelist[section] no! \stoptext ------------------------------------------ I was looking in definitions for some font-size dependent line setting, I also tried to \setuplist[section]{style=\baselineskip=12pt\lineskiplimit=-10pt} but without success to lounging on the grid. Can somebody help me, please? vit

TABLE feature wishes
by Eckhart Guthöhrlein 09 Aug '05

09 Aug '05

Hi again, as dicussed some time ago, here comes the reminder of what context lacks concerning table typesetting. I will concentrate on \bTABLE .. \eTABLE, since it is much more powerful than the older ones (and I do not know much about linetables). In order to be able to typeset tables with satisfactory results, I personally need at least the following missing features: - Control over horizontal cell spacing and vertical row spacing, independently of each other. This can not be done currently, since the rulethickness parameter affects all frames of a cell. - Better support for horizontal rules, without affecting the actual cells. I would like to say e.g. \HL between rows to get a line. A command to span just a selection of columns is also necessary. Although I have tricked TABLE into doing what I want with dummy rows and metapost graphics, this is not a very nice solution. Concerning rules, I would suggest further options like trimming, but maybe this can be postponed to prevent this message from becoming too lengthy. For those interested, my ideal table in this respect is what the latex booktabs package provides: ftp://ftp.dante.de/pub/tex/macros/latex/contrib/booktabs/booktabs.pdf. In addition, it would be highly desirable to have the possibility - to insert material before and after the entry of a cell, eg have \bTD[before=(,after=)]x\eTD typeset (x). - to have hooks which do something with entries, eg \bTD[hook=\framed]x\eTD gives a framed x. How are the chances that the above will be supported by context in the near future, or ever? Greetings, -- Eckhart
