puzzled

I'm trying to put a right brace to the right of a framed box and thought I could do this: \starttext $\left. \framed[width=7cm,align=right,height=fit]{ something here \hairline \vphantom{something here} \hairline \vphantom{something here} } \right\} \text{entries for something}$ \stoptext but the brace is almost exactly twice as tall as the framed box. All help is appreciated! Thanks Marko

Texfont on i-Installer for Mac OSX
by Nigel King 29 Mar '03

29 Mar '03

Guys, Gerben Wierda has done an excellent job producing i-Installer for the Mac OSX which works with LaTeX etc very well. It is clear that many people are being introduced to TeX on the Mac now using this installer. Unfortunately there appears to be one problem with ConTeXt which is texfont. The tetex structure that Gerben has chosen is for the main fonts to be in /usr/local/teTeX/share/texmf.tetex/fonts Texfont will not recognise this location and the fonts in it and I suspect it is because of the full stop in texmf.tetex Evidence for this is in the following Running the single command texfont --en=8r --ve=urw --co=courier --so=auto Should work but returns processing aborted : unknown tex root /sw/share/texmf/ Clearly texroot is set incorrectly so forcing that texfont --en=8r --ve=urw --co=courier --so=auto --fontroot=/usr/local/teTeX/share/texmf.tetex/ Should work but returns processing aborted : unknown subpath ../fonts/afm/urw/courier And yet /usr/local/teTeX/share/texmf.tetex/fonts/afm/urw/courier/ucrb8a.afm Exists Are there any other possible reasons for this problem I have had some success now with fonts using adobekb.tex but the situation is not wholly satisfactory and I think I would really like texfont to work. -- Nigel

Hi all, I want to make a twoline header in a framed box: \setupheads[sectionnumber=no] \define[1]\Sectioncommand{\framed[frame=off,bottomframe=on]{#1}} \definehead[Section][section] \setuphead[Section][textcommand=\Sectioncommand] \Section{first line\crlf second line} I want to get something of the kind first line second line ------------- but my result is first linesecond line ----------------------- The contents seems to be good, the two lines appear.

hyphenation in \type{....}?
by Patrick Gundlach 28 Mar '03

28 Mar '03

Dear ConTeXt hackers, I am a bit confused: as stated in the manual, \type{...} does not hyphenate (in contrast to \typ{...}), but in the following example, it does: \enableregime [il1] \starttext ist zwar nur einem ist zwar nur einem \type{averylongword averylongword averylongword averylongword} \stoptext How do I get garanteed-non-hypenated-typing?

color band
by Idris S Hamid 27 Mar '03

27 Mar '03

Dear syndicate, For a book cover I want a green-colored rectangular band, centered, at the very top of the page, with text in some other color (to be determined) overlapping the band. The band is small, just, say, 2cm high and 12 cm wide. Since it's at the top it is surrounded by white on only three sides. I'm not even sure where to get started here (I don't think the LaTeX Graphics Companion will be much help:->) Here is part of my present layout. I'll have to put this band in the topspace and increase it, I presume: \definepapersize[journal][width=5.5in, height=8.5in] \setuppapersize[journal][letter] \setuplayout[width=middle, | height=19cm, | footer=0cm, | header=0cm, | topspace=28pt, | location={middle,doublesided}, | marking=on] I hope the solution is Plain-compatible since I may have to use Gamma for some Arabic insertions. Otherwise I'll have to eps those insertions. Thnx in advance Idris

Paragraph setup
by kopszak＠mnw.art.pl 27 Mar '03

27 Mar '03

Hello, I was trying, without convincing results, to define a float containing a text block which would be typeset in the top right corner of a page and would have specified width. Also if there would happen another float like this on the page it should be typeset below the first one and the text should flow around both of them. Is there any simple way to do that? Thanks in advance. Piotr -- Piotr Kopszak, Ph.D. Polish Art Gallery, National Museum in Warsaw -----------------------------> http://kopszak.mnw.art.pl/

textbackgrounds
by Patrick Gundlach 27 Mar '03

27 Mar '03

Dear ConTeXt users, i have a question about textbackgrounds. Is there a) something like \setuptextbackground[all][frame=on,...] that sets frame=on for all the textbackgrounds out there? Or better: b) is there any way to inherit parameters? \definetextbackground[A][frame=off] \definetextbackground[B][A] so that B also has frame=off set? Patrick

textbackground again...

Hi there, why is frame=on and the offset ignored?

A change in textext Metafun maco?
by Michal Kvasnicka 27 Mar '03

27 Mar '03

Good noon. I have updated to the new ConTeXt and some of my documents failed to work. I use the FunnyFrame example from the Metafun manual. With the old ConTeXt all worked well. Now I can see in the title of a frame just "unknown". I played a little with the mpgraph.mp and I suspect the macro textext not to work well. Or in the same way as before. Where can be a bug? (Well, I updated only TeX, Metapost, and Perl part of ConTeXt and generated formats -- I didn't updated the ConTeXt stuff for plain or for LaTeX). Can you help me? Many thanks. Michal Kvasnicka
