latest ConTeXt and \quote
by Alan Bowen 30 Aug '06

30 Aug '06

I updated to 2006.08.29 11:11 and find now that \quote{} produces double quotes (“ ”) rather than single quotes (“ ”). \quotation{} still has its expected effect. Is this a bug or has something gone awry with my installation? Cheers, Alan

layout question
by richard rascher-friesenhausen 29 Aug '06

29 Aug '06

Hello, i have a simple (?) layout question. I want to typeset a doublesided text with a larger margin on one side. This margin will be filled with 'margin images' or 'margin remarks'. But sometimes, larger images have to be placed in the text+margin. Which commands, options or setups are correct, to get the same results on odd and even pages? In the attached pdf file, odd and even pages behave different, using a simple setup (see tex file). richard -- ============================================================================== Richard Rascher-Friesenhausen MeVis -- Centrum fuer Medizinische Diagnosesysteme und Visualisierung GmbH Universitaetsallee 29 D-28359 Bremen email: richard(a)mevis.de, richard.rascher-friesenhausen(a)hs-bremerhaven.de www : http://www.mevis.de/, http://www.hs-bremerhaven.de/ fon : +49 - 421 - 218 7707 (mevis) fax : +49 - 421 - 218 4236 (mevis) ============================================================================== % output=pdf %======================================================================= % begin of file *layout-test.tex* %======================================================================= % richard(a)mevis.de % layout %----------------------------------------------------------------------- \setuppapersize[A4][A4] \setuplayout[leftmargin=0.5in,rightmargin=2.3in,textwidth=5in] \setuplayout[width=fit, backspace=\dimexpr(\leftmarginwidth+\leftmargindistance)] \setuppagenumbering[alternative=doublesided] %======================================================================= \starttext %======================================================================= The very first page with a small image in the (bigger) margin. \placefigure[inmargin]{a margin image} {\framed[width=\marginwidth,height=3cm]{image}} \input tufte An now a larger image in the text and margin are \placefigure[here,inmargin]{a text+margin image} {\framed[width=1.2\textwidth,height=3cm]{image}} \inmargin{Tufte text} \input tufte %----------------------------------------------------------------------- \page %----------------------------------------------------------------------- The second page with a small image in the (bigger) margin. \placefigure[inmargin]{a margin image} {\framed[width=\marginwidth,height=3cm]{image}} \input tufte An now a larger image in the text and margin are \placefigure[here,inmargin]{a text+margin image} {\framed[width=1.2\textwidth,height=3cm]{image}} \inmargin{Tufte text} \input tufte %======================================================================= \stoptext %======================================================================= % end of file *layout-test.tex* %=======================================================================

positioning a watermark
by Paul Jones 29 Aug '06

29 Aug '06

Hello, I am trying to create alternating watermarks behind the text of a book on odd and even pages. I was able to get this working with overlays fine, except that I could not figure out how to position them. (I would like them in the bottom outside corners) Using layers I could get them to repeat across pages if I \setupbackgrounds[text][text], but only the text on the odd pages showed up. I would really like to use \setupbackgrounds[page] so my offsets are from the edge of the page. So I guess I have a couple of questions. Is it possible to position overlays? Is it possible to repeat layers using [page]? Any guess as to why only the odd pages showed the watermark in the code below? Thanks for any help. paul %output=pdf \setuppagenumbering [alternative=doublesided] \setupcolors [state=start] \setupbackgrounds [text][text] [background=watermark,state=repeat] \definelayer [watermark] [position=yes] \startsetups watermark \doifoddpageelse {\framed[frame=off,foregroundcolor=gray]{\scale[sx=10,sy=10]{\rotate[rotation= 0.0]{forever}}}} {\framed[frame=off,foregroundcolor=gray]{\scale[sx=10,sy=10]{\rotate[rotation= 0.0]{together}}}} \stopsetups \starttext \setlayer[watermark][hoffset=1cm,voffset=1cm]{\setups{watermark}} \chapter{first} \dorecurse{10}{\input tufte } \chapter{second} \dorecurse{10}{\input davis } \chapter{third} \dorecurse{10}{\input zapf } \chapter{fourth} \dorecurse{10}{\input bryson } \stoptext

Bug in way=...?
by Aditya Mahajan 28 Aug '06

28 Aug '06

Hi, Is setupwhatever[way=....] supposed to be global? Suppose I \setupformulas[way=bysection] for a section, and want to switch back to \setupformulas[way=bytext] in the next section, it does not work. Similar behaviour happens with \setupcaptions. Consider the following minimal example. \starttext \setupformulas[way=bysection] \setupcaptions[way=bysection] \section{One} This is a test \placeformula \startformula a \stopformula \placefigure {test}{} \setupformulas[way=bytext] \setupcaptions[way=bytext] \section{Two} This is a test \placeformula \startformula a \stopformula \placefigure {test}{} \stoptext Is this a bug, or just a crazy user request?

New math feature requests
by Aditya Mahajan 28 Aug '06

28 Aug '06

Hi Hans and Taco, I am back with some more math request---one alignment construct, one inner math alignment construct, and one formula tagging request. These are primarily to "complete" the context math environments. I am posting here rather than on the dev list, so that other math users can also contribute. This is a loong mail. 1. Multiline equations (they are called multline equations in amsmath) This is used to write multiline formulas (where alignement does not make sense). The first line is left aligned, the last line is rightaligned and all the middle lines are middle aligned. The entire formula gets only one number. If the formulas are numbered on the right, then the formula number is located on the last line; if the formulas are numbered on the left, then the formula number is located on the first line. The alignment of a single line can be changed. The first and the last line have a gap equal to \multlinegap from the text border. If the formula is numbered, the gap is used only for the line without the number. I do not know what is a good syntax for this command. First of all, I think we should call it multiline (rather than multline as in ams). Then we can have \placeformula \startmultilineformula[gap=5pt] \NC f(x) = ax \NR \NC + bx + c + \NR \NC e \NR \stopformula This should come out as (assuming formulas are numbered on the right) 5pt gap |---f(x) = ax | <---- left aligned | + bx + c + | <---- middle aligned | + e (1) | <---- right aligned If the formulas are numbered on the left |(1) f(x) = ax | | + bx + c + | | + e---| 5pt gap If there is no placeformula in the front then |---f(x) = ax |<-- left aligned (5pt gap) | + bx + c + |<-- middle aligned | + e---|<-- right aligned with 5pt gap If should be possible to get the 2nd line right aligned by using \NC f(x) = ax \NR \NC[align=right] + bx + c + \NR \NC +e \NR I am not sure of the syntax and the above \NC...\NR is just to illustrate the point. PS: I do not use multline of amsmath frequently. If someone does use it, please read this carefully to ensure that I did not misread the manual. 2. In amsmath, most of alignment constructs exist in two forms: outer and inner. The mathalignment implemented in core-mat.tex corresponds to outer alignment. The inner alignment is same as outer alignment, but is only as wide as necessay. The most common amsmath inner alignment constructs are aligned and gathered. It is easiest to explain by means of an example. Suppose I want to type a x + b y = c `\ } (simultaneous equations) d x + e y = f / , I want to be able to do \defineinnermathalignment[aligned][n=2,left={\left.},right={\right\}}] \startformula \startaligned \NC ax + by \EQ c \NR \NC dx + ey \EQ f \NR \stopaligned \quad \text{(simultaneous equations)} \stopformula One crude way to implement this is as follows \def\startaligned{ %Whatever corresponds to left= \left. \framed[align=normal,frame=off,location=lohi] % I do not know how to do this in terms of hboxes \bgroup \vskip-\baselineskip %There should be a better way \startformula \startalign[n=2]} \def\stopaligned{ \stopalign \stopformula \egroup%end of framed % Whatever correspons to right= \right\} } \startformula \startaligned \NC ax + by \EQ c \NR \NC dx + ey \EQ f \NR \stopaligned \quad \text{(simultaneous equations)} \stopformula I am sure that this definition can be improved. The innermath environments should take three types of options (n=...,m=....,distance=....,etc, that are passed to \startalign; left=...,right=..., that put the left and right delimiters; and location=high|low|lohi that align the innermath environment to the baseline. Notice that the crude definition that I have given does not handle location nicely. I know Tex's limitation of scaling left and right delimiters on both sides of the math centerline, making it difficult to handle left|right and location correctly. It there is no easy fix, left|right can be left out. Such a construct will take care of aligned, gathered and split environments of amsmath. 3. Formula tagging amsmath allows formulas to be tagged. I will explain amsmath's behaviour and hope that Hans can come up with the context way of doing such things. Occasionally, one wants to tag a formula, e.g. \placefomrula[a] \startformula a x = b \stopformula \placetaggedformula[b]{*} \startformula x = \frac {b}{a} \stopformula should come out as a x = b (1) x = b/a (*) Notice that ( and ) correspond to left and right in setupformulas. It should also be possible to place a tag without these brackets, so \placetaggedformulawithoutbrackets[c]{**} \startformula b = ax \stopformula should come out as b = ax ** <--- no brackets here Maybe, instead of placetaggedformulawithout brackets, one can simply have \placetaggedformula[c][left=,right=]{**} but in such cases it is easy to get confused with the reference and options. I am not sure what is a good way to do this. It should also be possible to refer to these tagged formulas. So \in{formula}[b] should give * and \in{formula}[c] should give **. The tag should be set in text mode, so that one can say \placetagformula {Answer} and the Answer will come out in text mode. Thanks, Aditya

afterpage
by Paul Jones 28 Aug '06

28 Aug '06

Hello, I have used Latex in the past and have the following code that inserts information on certain pages using afterpage. Is there some way to do a similar thing in context? \usepackage{afterpage} \newcommand{\insertpagea}{\vbox to \textheight{\vfill This page inserted on page 3 \vfill}} \newcommand{\insertpageb}{\vbox to \textheight{\vfill This page inserted on page 4 \vfill}} \newcommand{\incpage}{\ifthenelse{\value{page}=3}{\insertpagea}{% \ifthenelse{\value{page}=4}{\insertpageb}{% \afterpage{\incpage}}}} \afterpage{\incpage} \begin{document} . . . \end{document} I am not sure if this could be done at a different level also, maybe with texexec or something. I basically have a requirement to insert content into a document on a specific page. After doing so the table of contents must still be correct. I am still fairly new in the Tex world so any help you can give will be very much appreciated. Paul

strutheight and (german) umlauts
by Peter Rolf 28 Aug '06

28 Aug '06

Hi, I just run into the problem, that \strutheight is lower than the height of some german umlauts (ÄÖÜ). % ----- \setupoutput[pdftex] \mainlanguage[german] \setupcolors[state=start] \starttext \showstruts \def\FOO#1{\framed[frame=off,background=color,backgroundcolor=green]{#1\strut}} \hbox{\FOO{AOU}\FOO{ÄÖÜ}} \stoptext % ----- Is this intended (and if so, why)? I need this for several boxes with a mp overlay as background and centered text. The height of the boxes is equal, so all text should be placed on the same baseline. Currently I box the text and set the height manually to \strutheight. But a more "global" solution would be prefered. Should I define my own gfx strut or just add one of those umlauts to \setfontstrut or ...? Dunno what is the best solution. Greetings, Peter

Hello, There's a strange behaviour with comments when using \startcomment...\stopcomment. In some cases the comments are skipped. The comment always appears with \comment{...}. Here is a summary of the tests I've done: Case OK: comment starting a paragraph Case KO: comment at the end of a single paragraph Case OK: another paragraph follows the comment Case KO: the comment is within a single paragraph Case NOK: the comment appears (not in the last paragraph), but not in the middle of the paragraph, but at the end. Case OK: comment starting a paragraph \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \startcomment blah blah blah blah blah blah \stopcomment \input tufte \stoptext Case KO: comment at the end of a single paragraph \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \input tufte \startcomment blah blah blah blah blah blah \stopcomment \stoptext Case OK: another paragraph follows the comment \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \input tufte \startcomment blah blah blah blah blah blah \stopcomment \input tufte \stoptext Case KO: the comment is within a single paragraph \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \input tufte \startcomment blah blah blah blah blah blah \stopcomment \input tufte \stoptext Case NOK: the comment appears, but not in the middle of the paragraph, but at the end \setupcolors[state=start] \setupinteraction[state=start] \setupinteractionscreen[options=max] \starttext \input tufte \startcomment blah blah blah blah blah blah \stopcomment \input tufte \input tufte \stoptext Regards, BG

This doesn't work here, too! The wiki said it should work. So, maybe there ist something broken in the meantime. In 'page-lay.tex' I found something with \setuplayout[odd][state=stop] \setuplayout[even][state=stop] so a.) Not alone \definelayout but also \setuplayout should work with odd|even. b.) Because there is something to stop here, there may be some need to start it? Btw. \definelayout[1][] doesn't work too. Wolfgang
