Simple problem with quotation paragraph
by Gerben Wierda 04 May '06

04 May '06

I am having a simple problem I can't solve by reading the manuals. I want to quote a fragment of a book which contains amongst others a discussion (Plato's Protagoras to be precise). Normally, my book has no whitespace between paragraphs and small indentation, but here I want a small amount of whitespace between paragraphs and also narrower. I'd like to setup some form of quotation paragraph style to use. I started out with \startquotation but I do not want quotes, so now I use startnarrower, but what I need is a paragraph style. Maybe another font (1pt smaller) is nice too. And noindenting while the rest of the book uses indenting. What I would like to do is something like \startBookQuote \stopBookQuote and on the inside I get a small whitespace between paragraphs, no indentation, a smaller font and a narrower textwidth. My last try was: \defineparagraphs[BookQuote][n=1,before={\indenting[never]\whitespace\startnarrower},after={\indenting[yes]\nowhitespace\stopnarrower}] in my environment file, but that gave me page breaks as soon as \startBookQuote was given and the quotes themselves do not receive page breaks, hence a quote more than one page (I have a few) ends up being a column of one page but just running from the page. So, it seems \defineparagraphs is out, because I do not get page breaks inside the quote. But what should I do? Thanks in advance, G PS. any sight on a decent ConTeXt book, btw? The manuals and wiki seldomly give me answers that work for me and often I find ConTeXt rather counterintuitive, e.g. setupparagraphs for something that is a table/column kind of thing, or confusing (\define vs \setup vs rest)

Part head centering and empty header
by Johannes Graumann 04 May '06

04 May '06

Hello I have coded my 'Appendix' like so: \setuphead [part] [ header=empty, footer=empty, alternative=middle, placehead=yes, resetnumber=no, number=no, style={ \ss\switchtobodyfont[60pt]\setupinterlinespace[line=2.8ex] }, page=right ] \startappendices \setuppagenumbering[way=bytext,partnumber=no,conversion=numbers,location={header,right}] \framed [% height=\textheight,% frame=off,% ] { \part{Appendices} } {\stopappendices} Which gives me a nicely vertically and horizontally centered title. One problem remains though: I can't get rid of the page number. The framed '\setuphead[part]' commands concerning header and footer are being overruled and I can't figure out how to have an empty header for just the page containing the frame. Thanks for any hints, Joh

dbcontext
by nico 04 May '06

Hello, Just for your information, dbcontext-0.1.0 is now released and available at http://dblatex.sf.net. It is another attempt to convert DocBook V4 documents to PDF by using ConTeXt, by using XSL stylesheets to translate from XML to context macros. It is quite experimental but can already handle basic documents. Regards, BG

Align with comments
by David Arnold 04 May '06

Aditya, I think a while back you provided an align example with comments, such as: 2x+3=5 Add -3 to both sides 2x+3-3=5-3 Simplify 2x=2 Divide both sides by 2 Etc. Could you provide another sample of this for us? Thanks.

Duplicate names in figure libraries
by David Arnold 04 May '06

04 May '06

Hans et al, I have two figure libraries, figlibSection1.xml and figlibSection2.xml. In the first, I have: <figure> <file>sec1rat1.png</file> <label>rat1</label> <copyright>College of the Redwoods Mathematics Department</copyright> <comment></comment> </figure> In the second, I have: <figure> <file>section2figs-mpgraph.1</file> <label>rat1</label> <copyright>College of the Redwoods Mathematics Department</copyright> <comment></comment> </figure> Now, section1.tex does: \usefigurebase[figures/figlibSection1] And later: \startbuffer[figure] \startcombination[3*1] {\externalfigure[rat1][width=.2\textwidth]}{(a)} {\externalfigure[rat2][width=.2\textwidth]}{(b)} {\externalfigure[rat3][width=.2\textwidth]}{(c)} \stopcombination \stopbuffer \placefigure [][fig:rat] {The calculator attempts to draw a continuous function when it shouldn't.} {\getbuffer[figure]} Section2.tex does: \usefigurebase[figures/figlibSection2] And later: \placefigure [][fig:rat1] {The numerator is zero at $x=-2$. This is an $x$-intercept of the graph. The denominator is zero at $x=3$. This is a vertical asymptote of the graph.} {\externalfigure[rat1]} All is fine if I compile section1.tex and section2.tex separately. But I have chapter6.tex with: \startproduct chapter6 \project book \startbodymatter \setupheadnumber[chapter][5] \chapter[chap:6]{Rational Functions} \component chapter6/section1 %Introducing Rational Functions \component chapter6/section2 %Zeros and Asymptotes \stopbodymatter \stopproduct When I compile this, the rat1 in section2.tex uses the rat1 meant for section1.tex instead. Any I can fix this other than giving unique names to everything?

separating layout from content: section blocks?
by Andrew D. Crouse 03 May '06

03 May '06

To whom it may concern, I have a large document with several distinct pieces. Each piece has different layout requirements. I can setup the layout before each piece, but I would prefer to separate the layout from content. Currently what is the best way to do this? I have tried defining section blocks and then specifying the layout for the section blocks between \startsectionblockenvironment [mySectionBlock] and \stopsectionblockenvironment commands. I have also tried the project, product, component, environment structure from the manuals. I have not had success with either method. I would be very interested to know the approach taken by more experienced users. Thank you for your help. Sincerely, Andrew Crouse

Accessing local files to launch helper progam using \useURL and \from
by Matthias Weber 03 May '06

03 May '06

Dear all, I am trying to us \useURL and \from with mixed success to access a local file so that it will be opened by a helper program. Both the program and the file to be opened by it reside in my local file system. Here is a small example: \setupcolors[state=start] \setupinteraction [state=start,color=blue] \useURL[cycloids][{file://3dxm/cycloids.stng}][][3DXM] \starttext \inmargin{\from[cycloids]} In this section, we study curves that are obtained by tracing a point on a fixed circle while it is rolling along another circle. \stoptext cycloids.stng is a file, that, when double-clicked, starts a program it is associated with. For trying, you can replace it by any other file that uses a special application to go with. Unfortunately, this *only* works with the pdf viewer in TeXShop (I am on a Mac). Preview doesn't do anything but beep, and Acrobat 6 offers a few choices, none of which is to open a helper application. Does anybody know if there is another way of launching helper applications when accessing documents? Also, while at it: When accessing local files, the URL appears to be absolute. Is there a way to use URLs relative to the location of the PDF that is referencing the URL? Thanks, Matthias

Mixing fonts ?
by WN 03 May '06

03 May '06

I am trying to learn more about font switching (read the font manuals but to no avail). The thing I am trying to do is : * For normal text I want to use the Times-Roman font * For math's I want to use a different font, i.e. Computer Modern I think I have to work with typescripts and use combinations of \setupbodyfont but I cannot work out the proper combination. Thanks for any help Regards Wim
