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

multipage table in columns
by Eckhart Guthöhrlein 09 Aug '05

09 Aug '05

Hi all, I have to build a table which should split over several columns (probably two) and, if necessary, across pages. I have tried this with \starttext \startcolumns[n=3] \setupTABLE[split=yes] \bTABLE \bTABLEhead \bTR \bTD Head \eTD \bTD Head~2 \eTD \eTR \eTABLEhead \bTABLEbody \bTR \bTD once \eTD \bTD once~2 \eTD \eTR \dorecurse{120}{% \bTR \bTD test \eTD \bTD test~2 \eTD \eTR } \eTABLEbody \bTABLEfoot \bTR \bTD low \eTD \bTD low~2 \eTD \eTR \eTABLEfoot \eTABLE \stopcolumns \stoptext This does something at least similar to what I had in mind :-) Problems: - As soon a page break is involved, the balancing algorithm gets totally confused. For example, the code above gives me three pages, with a single cell on the second one. The head is repeated only on the third page. - How can I make a column break trigger head repetition instead of a page break? - How to get the footer repeated at the end of each column, too? Furthermore, there are some old messages concerning captions for multipage tables, but I could not find a satisfactory answer. How can I get a caption on the first page and something like "Table x cont." on the following ones? Thanks, -- Eckhart

Czech sorting rules
by David Antos 09 Aug '05

09 Aug '05

Hello, I've tried to find something relevant about the terrible Czech sorting :-) The first thing to note is that there is a standard (from 1970 or so) that is not implementable in fact, it requires such stupid sorts like Karel IV < Karel III as one should sort it as the numbers were written in words (ctvrty, treti) :-) So in practice, there are more-or-less accurate approximations. Quite good intro is http://www.vitsoft.info/sortkit.htm The sorting is considered very reasonable if it conforms with order stated in http://www.fi.muni.cz/~adelton/l10n/cssort/cssort.table . Characters on a single line in the table are considered equivalent. Note the `ch' character that is sorted between h and i. This table contains accented letters that are not used in Czech (like crossed l, z dot above). It should IMHO be also completely OK for Slovak (as they, I hope, inherited the standard). I think that it would be completely OK to sort according to that table taking chars on single lines as equivalent. The modules the table is from implements a four-pass sorting algorithm that reflects pretty damn rules, see http://www.fi.muni.cz/~adelton/l10n/cssort/csort.c . An example of sorted sequences is http://www.fi.muni.cz/~adelton/l10n/cssort/sort.tab . The question is if it is reasonable to implement it internally in ConTeXt or to use an external module. An external Perl module was prepared by Tom Hudec once (he even modified the sorting table, he preferred all letters with `hacek (\v{})' to be greater than without \v. If you consider internal ConTeXt implementation feasible, I'd be happy if you commented the sorting macros a bit, so that I could contact native Czech users and fine-tune it. I'd like to consult it with our Czech TeX frieds, I don't feel myself to be a sorting expert (it's quite tricky, isn't it).
