TeXLive 2006
by Taco Hoekwater 22 Jan '07

22 Jan '07

Hi, I have good news as well as bad news. The good news is that the coming TeXLive will be nicely up to date when it comes to ConTeXt (currently at 2006.12.07). The bad news is that core-fnt and core-ext will not be included. Apparently, the first package that uses a certain directory becomes its 'owner' when it comes to TeXLive's distribution build scripts. Since there are already a number of fontpackages for LaTeX included, there is no way to add metrics for ConTeXt as well. I have proposed to look into the build scripts, but the reaction I received was luke-warm at best, so I am not going to persue this any further. I am sorry for everybody that wanted to see some of the third-party modules in TL. It should still be possible to have them included if one of you is willing and able to make the effort of renaming the used folders so as to avoid conflicts with LaTeX packages, but I simply cannot be bothered any more. Best, Taco

Inconsistent Reference Counting
by Mike Bird 01 Jan '07

01 Jan '07

References are classified as forward or backward based on comparison of \crossreferencenumber against the sequence number of the reference loaded from the previous pass. \crossreferencenumber is incremented on all reference definition writes including duplicates. References loaded from the previous pass do not include duplicates. Thus forward/backward classification (e.g. in \somewhere) is wrong in the presence of duplicate references. One fix would be to not increment \crossreferencenumber if this reference has already been written to the file. Does anyone have any suggestions how to do this? Thanks, --Mike Bird

mptopdf: produces PDF with 'unknown operator' error
by Sanjoy Mahajan 01 Jan '07

01 Jan '07

The following test file (included in the attached .zip) produces errors when test.pdf is viewed in xpdf (v3.0): Error (1004): Unknown operator 'D' Error (1006): Too few (0) args to 'J' operator =================== begin: test.tex ================== % xpdf error: % Error (1004): Unknown operator 'D' % Error (1006): Too few (0) args to 'J' operator \pdfcompresslevel=0 \defineoverlay [foregraphics] [\positionoverlay{foregraphics}] \setupbackgrounds [page] [background={foreground,foregraphics}] \starttext \hpos{r13}{4} \hpos{r23}{7} \quad \hpos{r24}{11} \startMPpositiongraphic{mypos:line} path pa, pb, pab ; numeric na, nb ; initialize_box(\MPpos{\MPvar{from}}) ; na := nxy ; pa := llxy..lrxy..urxy..ulxy..cycle ; initialize_box(\MPpos{\MPvar{to}}) ; nb := nxy ; pb := llxy..lrxy..urxy..ulxy..cycle ; if na=nb : pab := center pa -- center pb ; pab := pab cutbefore (pab intersectionpoint pa) ; pab := pab cutafter (pab intersectionpoint pb) ; pickup pencircle scaled 1pt ; draw pab withcolor .625yellow ; anchor_box(\MPanchor{\MPvar{from}}) ; fi ; \stopMPpositiongraphic \startpositionoverlay{foregraphics} \setMPpositiongraphic{r13}{mypos:line}{to=r24} \setMPpositiongraphic{r23}{mypos:line}{to=r24} \stoppositionoverlay hi \stoptext =================== end: test.tex ================== The simplest way to see the problem is to convert the intermediate EPS graphic to pdf by hand (with mptopdf), and that pdf file shows the same problem. So I run the following to get an uncompressed pdf file: texexec test.tex mptopdf test-mpgraph.1 pdftk test-mpgraph-1.pdf output test-mpgraph-1-uncompressed.pdf uncompress Then view either test-mpgraph-1.pdf or test-mpgraph-1-uncompressed.pdf (in xpdf). It's line 19 (" D J") in test-mpgraph-1-uncompressed.pdf that causes the problem. The original eps file (test-mpgraph.1) has a definition for D, which I think is "/D{[] 0 setdash}bd" (if I parsed the postscript right). But the converted PDF doesn't know the definition. Which may cause the J operator to have too few arguments. The attached zip file has all the files that result from running the above commands, including a (GNU) Makefile to reproduce the whole thing. I'm using the 2006.12.27 version of ConTeXt, with mptopdf 1.3.2, on Ubuntu Linux (tetex 3.0, xpdf 3.0). The files display correctly despite the warnings, but a more complex example (from which this came) has misplaced connecting lines. I don't know if it is caused by these operator problems. However, I figured it's worth worrying about this simpler case first, and only then seeing what problems remain in the more complex example. -Sanjoy `A nation of slaves is always prepared to applaud the clemency of their master who, in the abuse of absolute power, does not proceed to the last extremes of injustice and oppression.'

Hi, (switched mailing lists) Hans Hagen wrote: >> >>I do not know if someone will find it useful or not, but it seems like >>a nice feature to have :) I'll look into wrapping it up a bit first. This code is written very much for comp.text.tex posting: \modulonumber is already present in ConTeXt, my macro names are optimized for shortness, and there is a slower but better definition of the integer divide possible (without multiplication): \def\divisionnumber#1#2% {\Expr{(#2/#1)-((\modulonumber{#1}{#2})/#1)}} > see core-con.tex, such things have been there for years now -) > (not sure if it does the same as what taco code does) My macro does something that wasn't there yet: it calculates a 'week number' based on the current date: \weeknumber{31}{12}{2006} expands to 52 (and my macro is fully expandable). The internal macro \Jday calculates the current julian day, and that can help make \getdayoftheweek much shorter: \def\getdayoftheweek#1#2#3% {\normalweeday\Expr{\Mod{\Jday{#1}{#2}{#3}+1}{7}+1}}% Best, Taco

debian package on contextgarden.net
by Mojca Miklavec 27 Dec '06

27 Dec '06

Hello, There was no voice from Patrick for a long time, but in case he's still reading his mail occasionally: He wanted to upgrade the TeX distribution on contextgarden.net. Couldn't the new Debian package be used for that? (Which would probably mean that one would get/could experiment with XeTeX and perhaps even luatex "for free" then.) Mojca

ugly bug in sometxt
by Mojca Miklavec 22 Dec '06

22 Dec '06

Hello Hans, I don't understand how I managed not to spot this before since I use it frequently, but \sometxt seems to scale the labels according to the last defined label. In other words, if one defines one \sometxt{short} in the first graphic and one \sometxt{\dorecurse{10}{very }long} then the first text will be scaled to the length of the second one.

bib: 'note' from book entry appears in incollection entry
by Sanjoy Mahajan 13 Dec '06

13 Dec '06

The 'note' field in the entry for the book appears in the incollection entry as well. Here's a test file to show what I mean: =================== begin: test.tex ================== \usemodule[bib] \setupcolors[state=start] \setupbibtex[database=talk] \setuppublications[alternative=num] \starttext See \cite{Ericsson:2006}. \placepublications[criterium=all] \stoptext =================== end: test.tex ================== It uses the bib file below. In the bibliography in test.pdf, the 'note' for the main book appears both with the book (which is good) but also with the chapter entry (which is not so good). It might be a general bibtex problem, because latex+bibtex does the same thing. Well, it does once I lost the battle with automatic crossref inclusion and had to cite the book entry by hand (the context bib module handled it fine citing just the chapter). =================== begin: talk.bib ================== @Book{Ericsson:Charness:Feltovich:Hoffman:2006, editor = {K. Anders Ericsson and Neil Charness and Paul J. Feltovich and Robert R. Hoffman}, title = {The {C}ambridge Handbook of Expertise and Expert Performance}, publisher = {Cambridge University Press}, year = 2006, address = {New York}, note = {This collection cannot be recommended highly enough}, } @InCollection{Ericsson:2006, author = {K. Anders Ericsson}, title = {The influence of experience and deliberate practice on the development of superior expert performance}, booktitle = {The {C}ambridge Handbook of Expertise and Expert Performance}, publisher = {Cambridge University Press}, crossref = {Ericsson:Charness:Feltovich:Hoffman:2006}, pages = {683--703}, year = 2006, chapter = 38, address = {New York}, note = {This collection cannot be recommended highly enough}, } =================== end: talk.bib ================== ConTeXt ver: 2006.12.07 18:22 MK II fmt: 2006.12.11 int: english/english -Sanjoy `Our society is run by insane people for insane objectives.'

bib entries missing full stops in "unpublished" and "book" types
by Sanjoy Mahajan 07 Dec '06

07 Dec '06

In the PDF output from this file (and bib file below), the full stop (a.k.a. period) is missing after "editors" ad the title in the first entry, and after the author ("...Foundation") in the second entry. ====================== proposal.tex ====================== \usemodule[bib] \setupbibtex[database=proposal] \setuppublications[alternative=num] \starttext Try \cite{HPL:2000} and \cite{GPLv3}. \placepublications[criterium=all] \stoptext ========================================================== ===================== proposal.bib ====================== @Unpublished{GPLv3, author = {Free Software Foundation}, title = {{\sc gnu} {G}eneral {P}ublic {L}icense revision}, month = {November}, year = 2006 } @Book{HPL:2000, editor = {John D. Barnsford and Ann L. Brown and Rodney R. Cocking}, title = {How people learn: Brain, mind, experience, and school}, publisher = {National Academy Press}, year = 2000, address = {Washington, DC}, edition = {expanded}, } ===================== end proposal.bib ====================== It works fine in latex with the same proposal.bib, using this latex file: ====================== tlatex.tex =================== \documentclass{article} \begin{document} Try \cite{HPL:2000} and \cite{GPLv3}. \bibliographystyle{plain} \bibliography{proposal} \end{document} ====================================================== I tried comparing the {book} and {unpublished} code in cont-no.bst and plain.bst (latex) but didn't have much luck figuring out why the full stops are missing. I've never noticed it with regular books (with just authors), only with editors. And I hadn't tried an unpublished entry before with ConTeXt. context version: 2006.11.22 11:02 / Ubuntu Linux / i386 BibTeX 0.99c (Web2C 7.5.4) p.s. Should this mail go to dev-context or to the main list? -Sanjoy `Our society is run by insane people for insane objectives.' (John Lennon)
