blank chapter last page
by M.guravage 20 Dec '05

20 Dec '05

Hi, ConTeXt's default behavior is to insert a page, when necessary, to force a new chapter to begin on a right hand page. One consequence when using running headers is that they appear on these extra pages too. I use the following code to control a chapter's opening page. % Define heads for chapter opening pages \definetext[chapterstart][footer][pagenumber] \setuphead[chapter][header=empty,footer=chapterstart] I would like those inserted extra pages to be completely blank. Any suggestions how I can disable the running headers for those pages? Thanks. Cheers, Michael A. Guravage

"Degrading" TABLE column
by Duncan Hothersall 20 Dec '05

20 Dec '05

I'm trying to solve a problem with a TABLE in a large-ish (600 page) book. The table occurs in an appendix, and the contents of one column are spilling out into the next column on the right. The weird thing is that when I process just that bit of the book, the effect is much smaller, and when I process the whole book (with the table near the end), the contents move all the way to the other side of the next column, moving almost a full column's width to the right. I will try to work up an example, but in the meantime, does this ring a bell with anyone in terms of something (an offset value, and alignment parameter?) which "degrades" over the course of a large run, such that the effect is minimal in a small document, but visible at the end of a large one? Thanks, Duncan

Exercise sets
by David Arnold 19 Dec '05

19 Dec '05

All, I'd like to design an exercise environment that will keep both the exercise and solution together. Something like: \startExercise Blah, blah, blah. \startSolution Blah, blah, blah \stopSolution \stopExercise At a higher level, something with parts, like: \startExercise Blah, blah, blah, ... \item Blah, blah, blah, ... \startSolution Blah, blah, blah, .. \stopSolution \item Blah, blah, blah, ... \startSolution Blah, blah, blah, .. \stopSolution \item Blah, blah, blah, ... \startSolution Blah, blah, blah, .. \stopSolution \stopExercise I'd like the exercises to get typeset in place, but the even solutions should go to the end of the text. Has anyone done something similar in Context?

Re: [Aleph] OpenType-to-TeX and other musings...
by Idris Samawi Hamid 19 Dec '05

Thank you Taco and Gábor for your valuable comments-) Based on both of your comments, it seems that the most practical approach in the short run is for Aleph (whose raison d`etre is more focused on the short run->) is to just treat otf's like cid/enriched type1 fonts (a la Latin Modern), which is what ConTeXt (and I guess LaTeX too) are already doing (with smart encodings, etc.) The main thing that aleph offers on this front is >256-glyph encodings. Simple otp's could provide switches to turn on needed features (small caps, superiors, swashes, etc) in a large font without clogging the system with multiple encodings (Occam's razor); only a single encoding vector for the entire raw font would be needed. I know that loading encodings in ConTeXt would certainly be a lot simpler-) On Sat, 17 Dec 2005 06:13:21 -0700, <gabor.bella(a)enst-bretagne.fr> wrote: > 3) OpenType fonts, as Taco has already mentioned, have a declarative > nature: they tell you what to do but not how to do it. In the short run, for Aleph's purposes, these declarations and much/most/all of the metainfo can be treated as "suggestions" for the otp designer to consider in implementing things. There is no need to treat them as something "holy". Based on your comments and my other research, I will focus on enriched/CID type1 (which I guess is equivalent to cff-flavored opentype) font solution in my own work, and not worry about otf declarations for now. In the long run, of course, it would be great if a rewrite of Omega could execute a complete implementation of otf functionality. I wish dear Yannis and Gábor the very best in this regard!

TUO loading bug
by Taco Hoekwater 19 Dec '05

19 Dec '05

Hi, Renaud AUBIN wrote: >> >> > [failing \cite commands in a component file] I've found the problem, and it is in fact not related to the bib module (and not really to the project structure either). The real culprit was a bug in the tuo file loader, triggered by your \useencoding[ffr] in the environment file. Your environment file is loaded *after* \startproduct (which implies \starttext), and therefore the switch comes too late. Moving the three french language related lines to the stop of the actual prd_phd.tex file (before \starttext) solves the problem. (What follows is for Hans' benefit mostly) Nasty little bug, this. I only found it because eventually, I decided to test the citations using explicit "\in{}[]" and found out that that didn't work either. I've attached a minimal file demonstrating the bug. Here is the problem in the tuo: \thisissectionseparator{-} % <= NOTE! .... \twopassentry{floatdata}{0}{1::1} % <= WRONG, loading of .tuo aborted \twopassentry{float}{1}{1} When I remove either this float, or the \useencoding line, all is fine, but simple redefining \dosavefloatdata was not enough apparently, because that did not work. Cheers, Taco

mfun-004.tex \startuseMPgraphic

Hans, In mfun-004.tex, I find: \startuseMPgraphic{axis} tickstep := 1cm ; ticklength := 2mm ; drawticks unitsquare xscaled 4cm yscaled 3cm shifted (-1cm,-1cm) ; tickstep := tickstep/2 ; ticklength := ticklength/2 ; drawticks unitsquare xscaled 4cm yscaled 3cm shifted (-1cm,-1cm) ; \stopuseMPgraphic \startlinecorrection[blank] \startMPcode \includeMPgraphic{axis} drawpoint "1cm,1.5cm" ; \stopMPcode \stoplinecorrection If the axis graphic is going to be "reused" over and over again, why didn't you use \startreusableMPgraphic?
