Weird things...
by Fabio Mancinelli 27 Dec '05

27 Dec '05

Hi all... I would like to report a weird behavior when compiling the attached tex file... If I put the background layer definitions before the columnset definitions everything works well. \useexternalfigure[test][buttons][frame=true] \definelayer[graphics][x=0.5cm,y=2cm,width=\paperwidth,height=\paperheight] \setupbackgrounds[page][background=graphics] \definelayerpreset[lefttop][corner={left,top},location={right,bottom}] \setlayer[graphics][preset=lefttop]{\externalfigure[test]} \definecolumnset[threecolumns][n=3,distance=12pt] \definecolumnsetspan[spantwo][n=2] \definecolumnsetspan[spanthree][n=3] \definecolumnsethsize{threecolumns}{1}{1}\OneColumn \definecolumnsethsize{threecolumns}{1}{2}\TwoColumns \definecolumnsethsize{threecolumns}{1}{3}\ThreeColumns If I put them after then I get an "ERROR: Bad character code (648)" \definecolumnset[threecolumns][n=3,distance=12pt] \definecolumnsetspan[spantwo][n=2] \definecolumnsetspan[spanthree][n=3] \definecolumnsethsize{threecolumns}{1}{1}\OneColumn \definecolumnsethsize{threecolumns}{1}{2}\TwoColumns \definecolumnsethsize{threecolumns}{1}{3}\ThreeColumns \useexternalfigure[test][buttons][frame=true] \definelayer[graphics][x=0.5cm,y=2cm,width=\paperwidth,height=\paperheight] \setupbackgrounds[page][background=graphics] \definelayerpreset[lefttop][corner={left,top},location={right,bottom}] \setlayer[graphics][preset=lefttop]{\externalfigure[test]} I have spent one hour trying to figure out what was wrong with my file and only by hasard, after having done some experiments, I put the things in the "working" order. Why this happens? See you, Fabio

Thank you Taco and Mojca. I had tried with \guillemotright and \guillemotleft based on a latex manual I found in the web. Since it didn't work, I then tried the \ll and \gg combination. Thank you Taco for the right syntax of the keywords.

Invisible Friends: I am trying to use \ll and \gg instead of quotation marks. The problem is that they are too big for my taste. What would be the easiest way to make them, say 0.75\bodyfontsize ? thank you Ciro PS: thank you for the help with the upside down question marks...

Passing text to Metapost functions
by David Arnold 27 Dec '05

27 Dec '05

All, I'd like to do something like this: create_axes(xmin,xmax,ymin,ymax,ux,uy)(x); Where x will be a label for my x-axis. But once in a while it might be t or u or some other thing such as "Days." I want to use it like this: beginfig(0); %initialize window parameters numeric xmin, xmax, xscl, ymin, ymax, yscl; xmin:=-5; xmax:=5; xscl:=1; ymin:=-5; ymax:=5; yscl:=1; %initialize scale numeric ux, uy; (xmax-xmin)*ux=4in; (ymax-ymin)*uy=3in; %create-axes function vardef create_axes(expr xxmin, xxmax, yymin, yymax, uux, uuy)(text xlbl)= drawdblarrow (1.05*xxmin*uux,0)--(1.05*xxmax*uux,0); label.rt(btex $xlbl$, (1.05*xxmax*uux,0)); drawdblarrow (0,1.05*yymin*uuy)--(0,1.05*yymax*uuy); enddef; create_axes(xmin,xmax,ymin,ymax,ux,uy)(x); endfig; end. Two questions: 1. How can I do this in plain metapost? 2. What would be the "Context Way?"

Columns (text alignment)
by Fabio Mancinelli 27 Dec '05

27 Dec '05

Hi everybody. I am experimenting with ConTeXt and columns. I am creating a simple style and I setup 3 columns and redefined some heading (section, subsection, subsubsections). Now the problem is that the text at the end of the columns is not aligned (i.e., the columns end at different heights). I thought that this was due to the \blank commands that I specified as before and after parameters in the heading definitions, but even by using the flexible modifier doesn't change that behavior. I don't know where the problem is. The tex file is attached. Thank you, Fabio P.S.: By using the attached file, I cannot specify the position parameter for \placefigure. If I write \placefigure{Name}{\externalfigure[...} it works. \placefigure[btlr]{name}{\externalfigure[...} does not. Weird. P.P.S.: I was reading the columns.pdf "tutorial". I saw that a \definecolumnsethsize command is used but I haven't found any documentation about that command anywhere. I use width=2\textwidth which seems to produce the same effects (2 columns span).

All, In: def hlingrid (expr Min, Max, Step, Length, Width) text t = image ( for i=Min step Step until Max+grid_eps : draw (origin--(Width,0)) shifted (0,i*(Length/Max)) t ; endfor ; ) ; enddef ; What does the image command do? Where is it documented?

Table of content
by Willi Egger 26 Dec '05

26 Dec '05

Dear ConTeXters, At the moment I am bit at a loss. I should prepare a document, wherein there will be a difference between one chapter title and the respective row in the table of contents. What it should become looks as follows: \chapter{This is the title of the chapter} In the table of contents it should show up as: Epilog: This is the title of the chapter So the question is, how to get the word Epilog into the table of contents in front of the chapter title, neatly aligned with the rest of the table of contents. Cheers Willi

Except Celtic, Thai, Arabic and Hebrew (although the letter names for Hebrew are almost completely defined) almost all the windows and ISO regimes are OK, just some glyphs are missing (which are, or at least were, missing in Unicode vectors as well). If anyone has suggestions for names for the following characters, 6 additional regimes can be fully supported: windows-1251 and iso-8859-5 2116 NUMERO SIGN windows-1253 0385 GREEK DIALYTIKA TONOS 2015 HORIZONTAL BAR 0384 GREEK TONOS windows-1258 0300 COMBINING GRAVE ACCENT 0309 COMBINING HOOK ABOVE 0303 COMBINING TILDE 0301 COMBINING ACUTE ACCENT 0323 COMBINING DOT BELOW 20AB DONG SIGN iso-8859-7 20AF DRACHMA SIGN 037A GREEK YPOGEGRAMMENI 2015 HORIZONTAL BAR 0384 GREEK TONOS 0385 GREEK DIALYTIKA TONOS iso-8859-10 2015 HORIZONTAL BAR Mojca
