Hello, I'm having some trouble with MPgraphics; here is a minimal example: ............................. \setupoutput[pdftex] \runMPgraphicstrue \setuppapersize[S6][S6] \setupcolors[state=start] \startMPinclusions numeric u; u=.8cm; path AX; AX = drawdblarrow (10u,0) -- (0,0) -- (0,10u); \stopMPinclusions \starttext \startuseMPgraphic{dummy} pickup pencircle scaled 1mm; draw AX withcolor blue; label.rt(textext("$3x^2+\pi$"), (5u,6u)); \stopuseMPgraphic \placefigure[left]{bla.bla}{\useMPgraphic{dummy}} \input dawkins \stoptext ............................. After compilation with texexec I get "unknown" instead of the expected label. What is wrong with me?

notes on columnset typesetting (not only about)
by Vit Zyka 27 May '06

27 May '06

Dear ConTeXters, surprisingly, in this e-mail you will find any bug report! It is a summary of my experience with typesetting of a little complex book layout. I have finnished it during a one year long winning battle. Thank to everybody who helped, especially of course to Hans. Thank you very much! ------------------ Next text can show, what is in present ConTeXt (or a bit older one) possible and what is still problematic. Firstly, let us show some examples: - transparency frames ftp://cmp.felk.cvut.cz/pub/cmp/users/zyka/vg-ex/vg05-ex-body1.pdf - two columnsets + marginals + figures + balancing ftp://cmp.felk.cvut.cz/pub/cmp/users/zyka/vg-ex/vg05-ex-body2.pdf - two columnsets + page float ftp://cmp.felk.cvut.cz/pub/cmp/users/zyka/vg-ex/vg05-ex-body3.pdf - three columnsets + floats ftp://cmp.felk.cvut.cz/pub/cmp/users/zyka/vg-ex/vg05-ex-encyk.pdf - content ftp://cmp.felk.cvut.cz/pub/cmp/users/zyka/vg-ex/vg05-ex-content.pdf - index ftp://cmp.felk.cvut.cz/pub/cmp/users/zyka/vg-ex/vg05-ex-index.pdf Legend for comming comments: + pros - cons ? dreaming about new feature ! attention = my (perhaps suboptimal) solution * note Comments: > grid + very powerfull and working support + works gracefully with columnsets and floats * avoiding orphans and widows was done manually by: = enlarging/decreasing figures = adding/removing (half)blank lines around heads ? if we want to do avoiding orphans and widows automatically, we would probably need the glue with DISCRETE STEP of stretch/shrink. Then we can say e.g. \let\bl=\baselineskip \setuphead [section] [before=\vskip1\bl plus1\bl withstep1\bl] to get vertical space before section head exactly 1 OR 2 \baselineskip height. Another solution with stepwise box: \vbox to2\bl plus2\bl withstep1\bl{\vfil heading \vfil} ! the only problem was in the table of contents + columns; from the first line there was a small shift between columns; perhaps \splittopskip? but setting it to large enough value does not solve it. > columnsets + very nice feature, really; after Hans improvement seems that some floats soes not dissappered now, but need to be carefull + floats insertion with specifying place ? for top float: automatically setting \placeongrid[{broad,high}] for bottom float \placeongrid[{broad,low}] to be vertically align with text on the rest of column(s) * balancing: only manually by setting: \setupcolumnsetlines[columnset_id][columnset_page][column][line] ! Not so painful if it not occures next: If there are many floats near balancing place they sometimes disappear or cause ignoring balancing - even if they can fit on the place. ? understand that automatical balancing with floats is extremly difficult * page floats: big improvements during the work. ! running marginal text continue through the page with only float = so you have to manually insert blank vertical margin on such place * header & footers: Hans did a new column marking: \getmarking[marking_id][column][last/first]. ! There are some problems [perhaps with expansion (different counter number and text)] if marking goes between two columnsets (framed chapters cross two cols in examples). = found acceptable hack but need more ivestigation on small examples for cleaning. > metapost inclusion + the most powerful, smooth and stable part of ConTeXt in my opinion (see random frames, circles with transparent graphics, lines with color shading) = if you have many (over 1024!) shadings (-> MP specials) do \settrue \manyMPspecials > index (register) + nice possibility to differentiate several groups (here 8 from which 4 have different visual marking of page number, see index example) - sorting: until this spring there was no satisfied backround for Czech sorting in newtexutil.rb till this spring. = I did dirty reimplementation of old texutil.pl for doing so * I have to have a look for new sorting now. - coupling: page numbers with group preserving (see example) = also in texutil.pl reimplementation > regime * my great discovery was that the regime IS \enableregime{latin2} % correct and NOT \enableregime{il2} % incorrect! > pseudo-small caps = http://wiki.contextgarden.net/Pseudo_Small_Caps > ... I provide the environment files (design definition) in case of somebody's interest. But suddenly they are very very very dirty. Partially due to my unsufficient ConTeXt knowledge, partially due to my despair during trying many ways to solve some problem, partially due to putting pathes to old ConTeXt (it was fresh of course when the work begins), ...: ftp://cmp.felk.cvut.cz/pub/cmp/users/zyka/vg-ex/vg05-env.tex (core) ftp://cmp.felk.cvut.cz/pub/cmp/users/zyka/vg-ex/vg05-mark.tex (markup) Best Vit

new release
by Hans Hagen 27 May '06

27 May '06

Hi, Today i'll upload a new release. Highlights: - some fixes/extensions discussed the last few weeks - xetex support adapted to using xdvipdfmx - ctxtools --update which will update your local context - an update feature in scite (can be used a example for other editors) - an integrated mpto (more robust that the binary approach) (btw, use textext instead of btex .. etex when possible) Taco will undoubtely give mnore details later. Keep in mind that you need to change the stubs: - preferable use texmfstart to launch scripts - texmfstart itself can be stubbed if needed - there is a ../scripts/context/stubs path in the zip Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

TABLE wishlist
by Johannes Graumann 26 May '06

26 May '06

Hello, I have finished my thesis using ConTeXt (with an XML only source - yeah ...). I found ConTeXt very usable, much more consistent in syntax than LaTeX (once one gets used to it) and up to the job ... the only thing that was not fixable is multipage table support with TABLEs. As pointed out earlier, there are issues with page breaking associated with it (see http://www.idyll.org:8081/JohSite/context/page-overflow-preceeding-a-split-…) - despite a patch by Hans. If, at one point, one of the developers is going to put some work into TABLEs, I have two requests aside from a reliable splitting algorithm: 1) A clearer numbering scheme ("Table 25a" and "Table 25b" rather than "Table 25a" and "Table 26b") for split tables. 2) an option that allows to repeat the table header, but replaces the caption after the first part of the split table with a configurable string as "Continued from page xyz". Having these 2(3) additions would be a great boon to ConTeXt (I believe). When I find the time in the next couple of days I'll start to return some of the insights gotten from the newsgroup during the thesis writing process to the community via the wiki. Thanks for your help guys! And thanks for this great package! Joh P.S.: I'd still be able to sneak in a last minute page breaking fix till Tuesday ;0) JG

format generation -- again!
by Thomas A. Schmitz 26 May '06

26 May '06

All, I just hit a snag in generating formats with --make --all. It works flawlessly on my computers running Mac OS X or linux, but ALan Bowen has a problem where .pat files with Unicode characters aren't recognized: (/usr/local/teTeX/share/texmf.local/tex/context/patterns/lang-us.hyp) language : patterns agr for agr loaded (n=24,e=agr,m=agr) (/usr/local/teTeX/share/texmf.local/tex/context/patterns/lang-agr.pat ! Nonletter. \rawcharacter ...r\or \or \or \or \or \or \or \or \or \or \or \... l.37 α2Ϊ 1 ? I compared the cont-en.log of our computers; the only real difference is the beginning: My log: This is pdfTeX, Version 3.141592-1.40.0-beta-20060213 (Web2C 7.5.5) (INITEX) 26 MAY 2006 19:42 entering extended mode \write18 enabled.

So the only difference that really could matter: 1. older version of pdf(e)tex; 2. natural.tcx is not called. Can anybody help? I'm unable to reproduce the problem here; I can generate formats both with texmfstart texexec --make --all and with fmtutil-sys --byfmt cont-en. Best Thomas

XeTeX "hangs"
by Mojca Miklavec 26 May '06

26 May '06

If I try to compile the folllowing code with XeTeX, it "hangs" (as if it was waiting for further input): \catcode`ð=\active \defð{^^f0} % only hangs for "F0", other numbers are OK \starttext ð \stoptext I didn't manage to test the same example with "plain" XeTeX (tetex is a bit misconfigured since the standalone ConTeXt is installed), but Jonathan says that it runs OK on his computer. Is my system broken again or are some other black forces working anywhere? Thanks, Mojca

Stuck in texmfstart
by Neal Lester 26 May '06

26 May '06

This morning, when I try to run texexec, texmfstart gets stuck in the loop at line 262. It seems that in my thrashing around yesterday I made some transient change to the environment (I shut this system down at night). Any idea what that is? I also applied a kernel patch, so I suppose that could also be the problem. Neal
