Hi, I can't to generate correctly the presentations that include metapost graphics. Could somebody tell me where is the error, please? I send a zip file with the test file using the pre-02 style.

Sieve of Eratosthenes
by David Arnold 17 Aug '03

17 Aug '03

All, I thought this might be a cool little programming challenge that might even make the metafun manual, as technique employed might be unique. I'd like to talk about the Sieve of Eratosthenes in class next week, specifically to find the primes between 1 and 100. This involves listing the integers from 1 to 100 in a 10 by 10 array. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 ... ... 91 92 93 94 95 96 97 98 99 100 1 is not prime and can be deleted from the discussion. They way the "sieve" works is to note that 2 is prime, but 4, 6, 8, etc, are not, because they are multiples of 2. The student now goes through the "sieve" crossing out all multiples of 2 (every other number). Then, 3 is a prime, and the student goes through the "sieve" crossing out every multiple of 3 (6, 9, 12, etc). Continue in this process, and the "sieve," when finished, will contain the primes from 1 to 100. Now, for my graphic requirements. 1. Make a grid 10 by 10 with gridlines. This will form 100 boxes to contain the numbers from 1 to 100. 2. Make the entire grid take up as much space as possible on us letter or a4 paper (for an overhead transparency). 3. Put the numbers centered in each "box" formed by the grid. Big numbers of course. Things to learn. 1. This might be a good example for outline fonts for Context users to study. So, setting up the fonts would be a cool example. 2. Would this be an array of boxes? 1 or 2-dimensional? 3. A nice loop for inserting the numbers automatically? 4. Thicker line styles and use of color? I'd love to see different approaches. A good opportunity to learn new technique and ideas for attacking this problem.

typescripts
by Henning Hraban Ramm 16 Aug '03

16 Aug '03

Hello together! My typescripts are now online: http://www.fiee.net/texnique/?menu=0-1-3&lang=en or directly: http://www.ramm.ch/fiee/texnique/material/typescripts.zip The archive contains only typescript files, no AFMs, PFBs, TFMs, VFs, MAPs or the like. Put them in texmf(-var|-local|...)/tex/context/user or in your project directory. Install the fonts with texfont (or with my also contained install-font.pl that calls texfont and does some other nasty work, but it's not very sophisticated, and you must edit the hardcoded TeXRoot yourself -- I know I should use kpsewhich, but...). All file names are supposed lowercase! (I had much problems with uppercase font names.) The archive contains typescripts for the huge (but not so beautiful) font families of URW with their spread from extra narrow to extra wide, and some other for ITC, Adobe and Linotype fonts. I tried to map all fonts to something reachable, e.g. if a family contained no italics, I mapped the next bolder font onto italics. Enjoy! Grüßlis vom Hraban! -- http://www.fiee.net/texnique/

typescripts for free ;-)
by Henning Hraban Ramm 15 Aug '03

15 Aug '03

Hello! I hope not to get into your spam filter with a "for free" message! ;-) I thought after all that begging and getting help I should do a bit for the community... I made a lot of typescript for URW and Lino fonts. If anyone is interested, I'll put them on my homepage (not the fonts, only the typescripts). BTW: I'll drop my "ConTeXt cookbook" project. I've never enough time to care about it like it was needed. Sorry and and big thanks to all who helped until now! Grüßlis vom Hraban! -- http://www.fiee.net/texnique/

Tobias, Very nice. Is there a setup that will typeset the labels as (1.1) and (1.1a)?

All, I am following this thread and I can report the same result as Holger. \setupformulae[align=right] \starttext \placeformula[david] \startformula \eqalignno{% left & right & \formulanumber \cr left & right & \formulanumber \cr } \stopformula \stoptext Gives this result. ! You can't use `\halign' in math mode. \eqalignno ...displ@y \tabskip \centering \halign to \displaywidth {\hfil $\... l.10 } May I ask how I can reference each of these equations separately in the text? That is, how can I give a different label to each equation in the alignment, then reference each one independent of the other? Thanks.

All right, I used \stopformula ... And I just found out the reason, it seems: I used \setupformulae[align=right] Then, if I use $$ instead of \startformula, I get centered formulas anyway.

Aligned numbered math formulas
by Holger Schöner 14 Aug '03

14 Aug '03

Hello, For a publication I need to typeset a lot of math formulas. To make them as comprehensible as possible, I need a few specialties, and would appreciate any suggestions you can provide: 1) Some of the formulas should be numbered, some not; and at the same time I would like to align several of them. For alignment I seem to be able to use \eqalign (or \startalign ... \stopalign from the t-amsl.tex sent around here lately). But if I place a \placeformula in front of this, the whole aligned block only gets one number; I would need a number for every line (or even better: a possibility to state, which lines should be numbered, and which not). By looking into core-mat.tex I found the commands \formulanumber and \subformulanumber which I can add after each line, if I want it to be numbered. Unfortunately they only set numbers, if the whole aligned block also is numbered (by using \placeformula), and they furthermore do not put the number beside the right margin, as is done by \placeformula, but directly where the \formulanumber appears. How can I enable the numbers even when not using \placeformula (or when using \placeformula[-]), and how can it put the numbers next to the right margin? 2) What are the keywords "alternative" and "indentnext" in \setupformulae meant for? Is there any documentation available concerning math formulae, besides "ConTeXt, the manual"? 3) I'd like to be able to set more than one line below large math operators, e.g. something like \sum_{m: \\ 1 \leq m \leq M}. Unfortunately this does not work as expected (it seems to conflict with the \startalign block). Is there another possibility? 4) Using the alignment features (\eqalign or \startalign, \stopalign) I often have the problem, that the (quite space consuming) formulas all appear on the next page, separated from its introductory text. I would like to have either also the introductory text put onto the next page (but neither \page[no] between text and formulas, nor \page[preference] before the introductory text work), or alternatively, to be able to (automatically) break the formulas inside the alignment block (whether alignment is kept up or not between pages does not matter for me). Is there a solution for either way?
