Your DTD has a number of problems. I have skipped most of this discussion, so I do not know what you want. But the content models are very vague: ANY for question and answer, and it seems you assume ANY for code as well. If you do not specify this more precisely, too much will be possible and nobody knows what to expect. A content model like %text;, declared as (#PCDATA|p|code)+, would be better. Schemas have some extra facilities here, but otherwise I am not sure why they would be preferable. The id in %person should be CDATA, as already remarked. Note that this assumes a tightly organized set of documents. You say nothing about the author or editor, so you assume that the id resolves into an entry in another document, and that the renderer knows which document so that it can generate a hyperlink. You might also use XLink language: xlink:href="author#hraban", which already indicates that the author can be found in the document author in the same directory, with the ID hraban. OTOH, this is less flexible w.r.t. the organization of the document set. Note that Docbook has provisions for QandA: qandaset, question, answer. I think docbook is a prime example of too wide a DTD. But it is useful to try and devise a DTD that is a subset of Docbook. It would make your documents processable with generic Docbook tools.

problem: long descriptions
by Zeljko Vrba 09 Nov '02

09 Nov '02

Hi! I'm writing reference manual for a C/C++ library and I have the following problem: When I define a description, long prototypes are not line-broken. For example, I've set up \definedescription [methref] [location=top,headstyle=\tt] When I have \startmethref{a very long prototype.........................} blah blah blah \stopmethref the argument is not line-broken and it goes out of the page boundary. The text shows properly only in the next line. I have something like the following in mind, but I don't know how to do it: I'd like the typeset layout to look something like this a very long prototype proto.. Text describing the method proto proto proto proto proto Text describing the method proto proto Text describinb the method More text describing the method. More text. More text More text. Prototype may be framed. The text widths should be 0.5 and 0.5 of textwidth for both the prototype and the description. I hope you understood what I want :) I was thinking something like typesetting prototype in the box and then using floating mechanism (\startXXXleft, would that work at all?), but is there a more straightforward way? Another unrelated question: is there a bold typewriter (CM) font somewhere?

Passing a string via texexec
by John Culleton 09 Nov '02

09 Nov '02

This is more of a convenience feature than a necessity, but here goes. I plan to personalize copies of an ebook in pdf format by putting the string: "This copy prepared for Joe Smith" on the page, perhaps in a footer. This means I have to recompile the book for each separate customer. It would save a minute if I could just pass a named string to pdfetex in the same way one passes a mode to the program. I am looking for something like: texexec --mode=ebook --string="Joe Smith" mybook.tex ...and then have a way to pick up that string in the TeX file and use it. All this does is save me from editing the file in every instance. If it is too big a deal forget it. -- John Culleton Able Indexers and Typesetters, Rowse Reviews, Culleton Editorial Services http://wexfordpress.com

Is your ConTeXt too slow?
by Jens-Uwe Morawski 09 Nov '02

09 Nov '02

Hi all (or mainly the users of Unix-like systems) after i've bought a new notebook and installed the recent Redhat Linux system i found that an updated ConTeXt runs very slow. First i thought that Hans had too much time and implemented a few thousand new features that need their time, but ... ... it is a queerer story. Here are the run times of an example document (many inline MP graphics, 18 pages, many terminal messages !!) on different terminal programs for X-Windows: gnome-terminal: 2 min 18 sec konsole (KDE-terminal): 1 min 30 sec xterm: 1 min 5 sec directly on the console (no X-Windows): 58 sec Normally i use the first. Hmm... ;-( Don't ask me for reasons, but if your ConTeXt is too slow, ask yourself if you run it on the right terminal -) Jens

Tabulate and vertical spacing
by mari.voipio＠iki.fi 09 Nov '02

09 Nov '02

Hello! This is a YASQ (Yet Another Stupid Question) that might well have an answer in the mail archives, but they still don't cooperate (at least I cannot find any links to a working archive)... How do I change the vertical line spacing in a tabulation? My default setting is \setupwhitespace[medium], nothing else. Most of my tabulations are fine with this, but in one certain set I'd need to bring the lines vertically closer together - how do I achieve this? BTW, how does ConTeXt understand lines of a tabulation - are they altogether one block or is each line equivalent to a block? (Windows analogy: Word handles the text in each cell as a separate paragraph; but Word isn't exactly a good typesetter, anyway.) Thanks for your patience, Mari Voipio Finland

Why does \struct affect line breaking?
by Bill McClain 08 Nov '02

08 Nov '02

This is perhaps more of a TeX question, and I'll take it to comp.text.tex next. But I encountered a problem when using \index in ConTeXt. I had my doc formatted exactly the way I wanted. But after I added \index entries throughout, I found that the line-breaking of some paragraphs had changed. The text became "looser", not packing quite as densely. Small changes, but significant to my layout. Experimentation showed that substituting "\strut" for "\index{...}" had the same effect. These should be invisible, and I don't see anything added, but the line-breaking is changed. I'm reading Eijkhout's chapter on "Line Breaking" in "TeX by Topic" but am not sure how to interpret it. Have I introduced "glue preceded by a nondiscardable item"? Would that be less breakable than the simple space that was there before? -Bill -- Sattre Press The King in Yellow http://sattre-press.com/ by Robert W.

startTEXapplication and music?
by Adam Lindsay 07 Nov '02

07 Nov '02

Hi ConTeXters, Here's another oddball question to see what's possible. I'm trying to get musictex (or musixtex, if the first one is a success) to work from within ConTeXt. Musictex code like that at the bottom of my message doesn't work directly in ConTeXt, and I don't feel the pressing need to make it work. However, it works fine when fed through pdftex. While doing a quick grep through the source files, I came across the \startTEXapplication and \startTEXpage macros used in the pstricks module, and they look like they handle the spirit of what I'm trying to accomplish. However, the pass through texexec again (and to some extent the dependency on ps2pdf, which I need to get from ghostscript and isn't in my TeXLive) means that ConTeXt fails on a tmp file, right? Would this be a good time to learn about buffers? Should I copy-paste the definitions involved with TEXapplication and modify them to something to my needs? Is there something that exists already that runs a simple pdftex on a code block and inserts it as a figure? thanks, adam musictex code follows: \input musicnft \input musictex \def\nbinstruments{1}\relax % a single instrument \generalmeter{\meterfrac{4}{4}}\relax % 4/4 meter chosen \debutextrait % starting real score \normal % normal 12 pt note spacing \temps\Notes\ibu0f0\qh0{cge}\tbu0\qh0g\enotes \finextrait % terminate excerpt -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Adam Lindsay +44(0)1524 594 537 atl(a)comp.lancs.ac.uk http://www.comp.lancs.ac.uk/computing/users/atl/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

MP graph auto axes
by Adam Lindsay 07 Nov '02

07 Nov '02

Hi Folks. This is not strictly a ConTeXt problem, but I was hoping there were enough MetaPost experts on the list that I might get an idea of what's going on, or at the least, where to go for more information. I think the MetaPost graphing features are fantastic. It produces very nice output, and automatically handles a lot of axis labelling that other packages don't bother with. However, it auto-labels the y-axis on the following three graphs very differently. I was wondering if this is a strict limitation in the axis ranges that MetaPost deals with gracefully, or if it might be a bug. I haven't seen any reference to the correct range for graph axes. I've tried many ranges, and some work, some don't. Would the MetaFont list be able to help? \usemodule[graph] %% This one works as it should. \startMPcode draw begingraph(130mm,35mm); setrange(0,0,10,22000); glabel.lft(btex {correct 0--22000} etex rotated 90, OUT); autogrid(itick.bot,grid.lft) withcolor .75white ; endgraph; \stopMPcode %% This one gives output, but yields incorrect labels \startMPcode draw begingraph(130mm,35mm); setrange(0,50,10,22000); glabel.lft(btex {wrong 50--22000} etex rotated 90, OUT); autogrid(itick.bot,grid.lft) withcolor .75white ; endgraph; \stopMPcode %% This simply gives up. \startMPcode draw begingraph(130mm,35mm); setrange(0,110,10,22000); glabel.lft(btex {failed 110--22000} etex rotated 90, OUT); autogrid(itick.bot,grid.lft) withcolor .75white ; endgraph; \stopMPcode Thanks in advance, adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Adam Lindsay +44(0)1524 594 537 atl(a)comp.lancs.ac.uk http://www.comp.lancs.ac.uk/computing/users/atl/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

grid and formulas
by Leif Albers 07 Nov '02

07 Nov '02

Hello again, I have the impression you can basically forget about the grid mode when using formulas. I started writing a simple text containing lots of math. When I turned on grid mode I basically saw ... well ... not at all what I expected. A simple example is: (watch the last line) -------------------- SNIPP -------------------- \setuplayout [grid=yes] \showgrid \starttext x \startformula x \stopformula x$\tilde I$ \stoptext -------------------- SNIPP -------------------- Note that in normal Text $\tilde I$ is correctly aligned. The combination with the big formula is a problem. But it is clearly not the only situation in which problems with grid and formulas occur. Leif Albers P.S. Is this list the correct place for bug reports?
