Dear All, I only very recently updated from ConTeXt ver: 2005.01.31 to ConTeXt ver: 2009.08.19 17:10 MKII Previously, using env-assign.tex as described in a 2006 PracTeX article worked fine. With the new version the drop shadow box is not rendered. This is the version of env-assign.tex I use: \startenvironment env-assign %D This is the environment file to prepare homework assignments in \CONTEXT. %D See accompanying Prac\TEX\ article for an introduction on how to use it. %D I use US letter paper and resonable margins. \setuppapersize[letter][letter] \setuplayout[ width=middle, height=middle, location=middle, topspace=1in, bottomspace=1in, backspace=1in, cutspace=1in, leftmargin=0in, rightmargin=0in, leftmargindistance=0in, rightmargindistance=0in, header=0.5in, footer=0.5in, headerdistace=0in, footerdistance=0in ] \setupwhitespace [small] \setupblank [medium] %\startMPenvironment[global] %\definetypeface % [MyFace] [rm] [serif] [palatino] [default] [encoding=ec] %\definetypeface % [MyFace] [tt] [mono] [modern] [default] [encoding=ec,rscale=1.1] %\definetypeface % [MyFace] [mm] [math] [euler] [euler] [encoding=ec,rscale=1.03] %\usetypescript[adobekb][\defaultencoding] %\setupbodyfont [MyFace, 11pt] %\stopMPenvironment \definefont [BigFontOne] [RegularSlanted sa 2.5] \definefont [BigFontTwo] [Regular sa 1.5] \setupcolors [state=start] \definecolor [colorone] [r=0.625,g=0,b=0] %dark red \definecolor [colortwo] [b=0.625,g=0,r=0] %dark blue \startuniqueMPgraphic{shadow} fill OverlayBox shifted (3pt,-3pt) withcolor .8white ; fill OverlayBox withcolor white ; draw OverlayBox withcolor blue ; setbounds currentpicture to OverlayBox ; \stopuniqueMPgraphic \defineoverlay [shadow] [\uniqueMPgraphic{shadow}] \def\assignmenttitle#1#2% {\framed[ width=broad, frame=off, align=right, foregroundcolor=colortwo, % I want a shadow around the title frame background=shadow] {#2\\{\colorone\BigFontTwo\Assigncourse}}} \setuphead[title] [ style=\BigFontOne, command=\assignmenttitle, before={\resetnumber[PROBLEM]\setuppagenumber[number=1]}, after={\blank[big] \bgroup \colortwo Assigned on: \expanded{\date[\Assignassigned]} \hfill Due on: \expanded{\date[\Assigndue]} \egroup\blank} ] \setupheadertexts [title] %D say \quotation{Solutions} while generating solutions \startmode[solution] \setupheadertexts [Solutions] [] \stopmode \setupfootertexts [pagenumber] \setupfootertexts [Assigned: \expanded{\date[\Assignassigned]}] [Due: \expanded{\date[\Assigndue]}] \definetext [title] [footer] [pagenumber] \setuphead [title] [header=high,footer=] \setuplabeltext [problem=Problem,solution=Solution ] \setuplabeltext [point=point,points=points] \def\assignment[#1] {\getrawparameters [Assign] [title=, course=, assigned=, due=, #1]% \title{\Assigntitle} } \defineenumeration [PROBLEM] [ text={\labeltext{problem}}, location=hanging, headstyle=\sc, headcolor=colorone, before={\resetnumber[formula]\page[desirable]}, after=\blank, ] \def\startproblem% {\dosingleempty\dostartproblem} \def\dostartproblem[#1]% {\startPROBLEM[#1]\dosinglegroupempty\dodostartproblem} \def\dodostartproblem#1% {\iffirstargument % Check if #1 = 1, use point, else use points \bgroup \colortwo (#1 \dopoints{#1}) \egroup \fi} \def\dopoints#1% {\doifelse{#1}{1}{\labeltext{point}}{\labeltext{points}}} \def\stopproblem% {\stopPROBLEM} \setupheader [text] [color=colortwo] \setupfooter [text] [color=colortwo] \setupitemize [each] [left=(,right=),stopper=,color=colorone] \setupitemize [1] [intro] \setupitemize [joinedup,packed] %D Use characters (a,b,\unknown) at the first level and roman numberals (i, ii, %D \unknown) at the second level. \setupitemize [1] [a] \setupitemize [2] [r] %D \macros{startsolution} %D In the default mode, the solution evironment should gobble its contents. %D I copy the definition of \tex{starthiding} to {\em hide} the solutions. \definebuffer [solution] \setupbuffer [solution] [local=yes] %D In solution mode, I redefine solution environment as an %D enumeration without a number. There are probably better ways to define this %D environment, but why reinvent the wheel? \startmode[solution] \defineenumeration [solution] [ text=\labeltext{solution}, number=no, headstyle=bold, headcolor=colortwo, location=serried, width=fit, before=\startsolutionbackground, after=\stopsolutionbackground ] %D The \filename{exam.cls} class in \LATEX\ allows you to put a frame around %D the solution and the frame breaks across pages. I wanted to put a frame %D around the solution, but something more informal than a rectangular frame. %D \CONTEXT's manual gave hints on getting different kinds of frames, and I %D finally settled for a randomized framed. The frame should %D break around pages, so I used \tex{textbackground}. \definetextbackground [solutionbackground] [ mp=background:random, location=paragraph, rulethickness=1pt, framecolor=colorone, width=local, leftoffset=1em, rightoffset=1em, before={\testpage[3]\blank[2*big]}, after={\blank[2*big]} ] %D The background in \tex{textbackground} is drawn using a useMPgraphic %D defined set by \mono{mp=}. I define a useMPgraphic \mono{background:random} %D to get the frame that I wanted. The code looks a bit complicated, because %D \tex{texbackground} is supposed to work in a multi||column documents. % A randomized frame \startuseMPgraphic{background:random} path p; for i = 1 upto nofmultipars : p = (multipars[i] topenlarged 10pt bottomenlarged 10pt) randomized 4pt ; fill p withcolor lightgray ; draw p withcolor \MPvar{linecolor} withpen pencircle scaled \MPvar{linewidth}; endfor; \stopuseMPgraphic %D An earlier attempt that draws a frame which is squeezed in the center. To %D use this change mp=background:random to mp=backgrond:squeezed in %D \definetextbackground above. \startuseMPgraphic{background:squeezed} path p; for i = 1 upto nofmultipars : p = multipars[i] topenlarged 10pt bottomenlarged 10pt squeezed 5pt randomized 1pt ; fill p withcolor lightgray ; draw p withcolor \MPvar{linecolor} withpen pencircle scaled \MPvar{linewidth}; endfor; \stopuseMPgraphic %D By default, the textbackground extends till the page boundary. This does %D not look good if a page break occurs when there is not enough material to %D fit in the page. So, we want to limit textbackground till the typeset %D material. This has not been interfaced yet, so I use a low level \TEX\ %D command. \chardef\kindofpagetextareas\plusone \stopmode %D I also wanted an English rule at the end of each assignment. \CONTEXT\ %D already defines an English rule. I load \filename{meta-txt.tex} to use it. \useMPlibrary [txt] %D I want the English rule to match the color scheme of the entire document. \setupMPvariables [EnglishRule] [color=colortwo, width=0.5\textwidth] %D I redefined \tex{stopcomponent} to add the rule at the end of the file. \let\normalstopcomponent\stopcomponent \def\stopcomponent% {\dosomebreak\nobreak \framedtext[frame=off,strut=no,align=middle,width=\textwidth] {\EnglishRule} \normalstopcomponent} \stopenvironment Any hints as to why this should not work anymore? Thanks and best regards, Marko

28 Sep '10

Dear list, Just to let you know - ConTeXt in MikTeX is back. There are some minor issues, but MKIV works almost out of the box. For the time being the version of ConTeXt in MikTeX is the same as in TeX Live. Mojca

\startcases...\stopcases alignment
by Martin 'golodhrim' Scholz 28 Sep '10

28 Sep '10

Hi everyone, I've got one big question, if I type something like \startcases \NC A \NC B\NR \NC CCCCC \NC DDDDD \stopcases Both the A and B are left justified and I would like to have them horizontally centered above the CCCCC and DDDDD. Is there a way to do so without a matrix usage or is for that the matrix the only solution...

realpage in register
by Steffen Wolfrum 28 Sep '10

28 Sep '10

Hi, I want to set up a register that shows the number of userpage and the number of realpage (used in pdf numbering). I was thinking of something like ... \def\BothPageNumbers#1 {#1 (\realpageno[#1])} \setupregister[index][pagecommand=\BothPageNumbers] ... only, I don't know how to address the corresponding realpage number ;o( Any idea?

pagenumbers in metafun
by Thomas A. Schmitz 28 Sep '10

28 Sep '10

Hi all, first, for thosw of you who went to the meeting: welcome back home from the ConTeXt meeting - looking at the slides and at the pictures made me really sad I couldn't come; I really hope I will be able to make it next year to Porquerolles! Here's a question that has been on my mind for a while now and that I would have loved to ask Taco and Hans at Brejlov: we now have shiny new \userpagenumber and \realpagenumber etc. Is any of these available and accessible from within Metafun? Right now, in a StartPage -- StopPage environment, I use NOfPages and PageNumber, but it would be convenient if we had access to userpagenumber as well (so the number can be reset etc.) All best Thomas

HowUgly setupregister
by Steffen Wolfrum 27 Sep '10

27 Sep '10

Hi, in MkII I used for formatting the index-register a command=\HowUgly \def\HowUgly #1{\doHowUgly#1\relax} \def\doHowUgly#1#2\relax{\iffirstregisterentry{\crlf \crlf $\backslash$blank[biggerblank]$\backslash$hangIndex$\{\backslash$bf #1$\}$}#2\else#1#2\fi} In MkIV there is no \iffirstregisterentry any more. What is the corresponding command today? Thanks, Steffen

getmarking does not use mark?
by Steffen Wolfrum 27 Sep '10

27 Sep '10

Hi, did I misunderstood something ... or is this simply a bug?! In that example below \getmarking uses the value of title ... and not of mark! (is there an other command to access the value of mark?)

unnumbered chapters
by Alan BRASLAU 27 Sep '10

27 Sep '10

A standard (wiki, manual) means of obtaining an unnumbered chapter is to use \title, but this does not create an entry into the toc. So one can create a new head, as in: \definehead [unnumberedchapter] [chapter] \setuphead [unnumberedchapter] [number=no] \definecombinedlist [content] [unnumberedchapter,chapter,section] \setuplist [unnumberedchapter] [headnumber=no] Bof! (pardon my French, as they say in polite circles) Much easier (or cleaner if you wish), using the structured syntax, is: \startchapter [number=no,incrementnumber=no, title={Conclusions}] \stopchapter (The {} are not necessary, but I believe that this may make things more readable, given the practice to enclose typeset text within curly braces.) A problem occurs, though, if we use labels, as in: \setuplabeltext [chapter={Chapter }] % with trailing space; blank by default (which Hans *never, ever* uses, by the way...) We then get: Chapter 1 First Chapter 2 Second Chapter Conclusions I think that the macros are missing a "label=no" option. Unless, that is, I am missing something obvious. Alan

figure numbering in appendices
by Mojca Miklavec 27 Sep '10

27 Sep '10

Dear list, The following code numbers the figures in appendices with Roman numbers in MKIV (while in MKII there is no difference at all). On top of that it doesn't restart the counter, but simply continues. In my opinion the Roman numerals should be easy to configure, but not set by default, and it particular figures should not be numbered with 1,2,3,IV,V,VI, ... (Also, usually the pages are numbered with lowercase roman numbers in frontmatter, not in appendices.) \starttext \startfrontmatter \placefigure{first}{first} \page \placefigure{second}{second} \stopfrontmatter \startbodymatter \placefigure{third}{third} \stopbodymatter \startappendices \placefigure{fourth}{fourth} \page \placefigure{fifth}{fifth} \stopappendices \stoptext Mojca
