I have put some files up on the web, generated with the latest beta. The (bad) output and source with the \definetextbackground line in: http://www.capdm.com/public/context/test-bad.pdf http://www.capdm.com/public/context/test-bad.tex The (good) output and source with the \definetextbackground line commented out: http://www.capdm.com/public/context/test-good.pdf http://www.capdm.com/public/context/test-good.tex I don't know if that will help? Thanks, Duncan

mp to pdf inline conversion adds whitespace (2006.09.26 beta)
by Sanjoy Mahajan 27 Sep '06

27 Sep '06

I'm using the 2006.09.26 beta, and noticed an extra gap before some external metapost figures. Here is a small test: ============================ test.mp ================= beginfig(1) draw fullcircle scaled (0.75in) xscaled 1.5; endfig; end ====================================================== With this test file, there is a whitespace of about 1cm between the first hairline and the ellipse: =================== test.tex (has 1cm gap) =========== \starttext \hrule \placefigure[force,none]{}{\externalfigure[test.1]} \hrule \stoptext ====================================================== If I convert test.1 to test-1.pdf and include that, all is fine: =================== test.tex (works) ================= \starttext \hrule \placefigure[force,none]{}{\externalfigure[test-1.pdf]} \hrule \stoptext ====================================================== If test.mp draws a square or rectangle instead of an ellipse, then there's no difference (both versions of test.tex work). -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

chinese characters in an itemize environment
by Lutz Haseloff 26 Sep '06

26 Sep '06

Hi all, If I use: \startitemize[m,packed] \item 三个小矮人 (some chinese characters) \item Die drei Männlein im Walde \stopitemize I get more space between the number and the text in the chinese line as in the latin line. The difference is .3-.4em depending on the fonts. How can I avoid this? Greetings Lutz

split natural table over columns
by Johan Sandblom 26 Sep '06

26 Sep '06

Is it possible to make a natural table split over columns or columnsets? For instance below I would like three cells in each column \starttext \startcolumns{3} \placetable{}{ \bTABLE[split=repeat] \dorecurse{9}{\bTR\bTD ha \eTD\eTR} \eTABLE} \stopcolumns \stoptext -- Johan Sandblom N8, MRC, Karolinska sjh t +46851776108 17176 Stockholm m +46735521477 Sweden "What is wanted is not the will to believe, but the will to find out, which is the exact opposite" - Bertrand Russell

calculations
by Henning Hraban Ramm 26 Sep '06

26 Sep '06

Sorry, I skimmed the TeXbook for an hour but couldn't find how to do simple calculations in TeX... This is a snippet from t-lilypond.tex: \def\LPscale{0.6315789} % downscale the image \ifvmode \getfiguredimensions[\bufferprefix lilypond-\the\lily! figures.pdf][]% % \def\FigWidth{\LPscale\figurewidth} \leavevmode \ifdim\FigWidth>\localhsize \!!dimena=\localhsize \advance\!!dimena by-\FigWidth \noindent\hskip\!!dimena \fi \fi \externalfigure[\lily!img][scale=1000\LPscale]% \egroup% I need to downscale every score to 63%, and the shown width check should use the corrected width. How can I do that? (FigWidth should be LPscale * figurewidth) Greetlings from Lake Constance! Hraban --- http://www.fiee.net/texnique/ http://contextgarden.net http://www.cacert.org (I'm an assurer)

Very strange bug related to textbackground
by Duncan Hothersall 25 Sep '06

25 Sep '06

I have been fighting with this one for ages, and have now narrowed down the culprit, but I do not understand why it happens. Latest (non-beta) ConTeXt, also tested in the live garden (same result): ---- \setupcaption[figure][align=right,location=bottom] \setupcaption[table][align=right,location=top] %\definetextbackground[irrelevant][frame=on] %uncomment for weirdness \starttext \placetable[here]{\vtop{\hsize=105mm \dorecurse{12}{sample content }}} {\bTABLE[option=stretch] \bTR \bTD High\eTD\bTD Middling\eTD\bTD Low\eTD\eTR \eTABLE} \dorecurse{10}{sample content } \placefigure[here]{\vtop{\hsize=105mm \dorecurse{12}{sample content }}}{\framed[width=\textwidth,height=50mm,align={middle,lohi}]{sample}} \stoptext ---- As it stands, this produces the expected output (a table and a figure each with long captions, with the captions set 'hanging'). However, if I define a totally unrelated textbackground (uncomment the third line), both captions veer off upwards, apparently a distance related to the number of lines in the title (play with the dorecurse numbers to see the effects). It doesn't seem to matter what the background is called, whether or not it is ever used, or what parameters it is given. I have no idea why something seemingly unrelated is having this effect; some reuse of a variable or unreset value somewhere? I would be really grateful if someone could [tell me how to] fix this.

This is not working here anymore. not w-mprun.1, not mprun.1 and not test.1 w-mprun.1 is build both the texish way (\input test.mp) and metafontish (input test.mp;) but is not found. Wolfgang

staticMPfigures can overrun output streams
by Sanjoy Mahajan 25 Sep '06

25 Sep '06

The following minimal file overruns the available output streams (version 2006.08.08 and context live): \starttext \dorecurse{16}{\startstaticMPfigure{\recurselevel} fill fullcircle scaled 1cm withcolor red; \stopstaticMPfigure} \stoptext At the end are the last few lines of the log. Here are the last few lines of the last few lines: ! Bad number (16). \openMPgraphicfile ...immediate \openout \MPwrite \MPgraphicfile .mp\relax \... After experiments and digging in the TeXbook I'm pretty sure the cause is as follows: The macro \openMPgraphicfile (supp-mps.tex) constructs the name of a new output stream and allocates a new write to it: \donetrue \@EA\@EA\csname newwrite\endcsname\csname\@@MPG\@@MPG\MPgraphicfile\endcsname Then \MPwrite is set to this stream number: \@EA\let\@EA\MPwrite\csname\@@MPG\@@MPG\MPgraphicfile\endcsname And then it's opened: \immediate\openout\MPwrite\MPgraphicfile.mp\relax which is where TeX complains about the bad number (16). The number gets that high because each static figure goes into a separate file, and each file requires a \newwrite. I thought it would not run out of streams because the allocation is all enclosed in \bgroup..\egroup (in \startstaticMPgraphic) and the \egroup would pop the write-stream allocation stack. But no such luck. The workhorse \alloc (p.347 of the TeXBook) uses a \global assignment to the control sequence. Here's a possible solution that works here but is a hack and may make unwarranted assumptions about control-sequence names. It require a new if to say whether we are processing a static MP figure, and then using a dedicated output stream for those writes. ======================== cut here ======================== \unprotect \newif\ifinstaticMPfigure \newwrite\MPstaticwrite \long\def\startstaticMPgraphic#1#2\stopstaticMPgraphic {\bgroup \instaticMPfiguretrue % value is restored by the \egroup \setMPrandomseedfalse \def\MPgraphicfile{#1}% no \jobname here \let\allocateMPslot \gobbleoneargument \let\deallocateMPslot\gobbleoneargument \let\runMPgraphic \gobbleoneargument \runMPgraphicstrue \enableincludeMPgraphics \currentMPgraphic\plusone % hack, else no close \startMPgraphic#2\stopMPgraphic \executeMPgraphicfile \egroup} \def\openMPgraphicfile#1#2% #1=alwaysopen #2=message {%\doifundefinedelse{\@@MPG\@@MPG\MPgraphicfile} % {\donetrue % \@EA\newwrite\csname\@@MPG\@@MPG\MPgraphicfile\endcsname}% % {\ifcase#1\donefalse\else\donetrue\fi}% \@EA\ifx\csname\@@MPG\@@MPG\MPgraphicfile\endcsname\relax %\donetrue \@EA\newwrite\csname\@@MPG\@@MPG\MPgraphicfile\endcsname % for the sake of plain usage \donetrue \ifinstaticMPfigure \let\MPwrite\MPstaticwrite \else \@EA\@EA\csname newwrite\endcsname\csname\@@MPG\@@MPG\MPgraphicfile\endcsname \fi \doglobal\addtocommalist\MPgraphicfile\MPgraphicfiles \else \ifcase#1\relax\donefalse\else\donetrue\fi \fi \ifinstaticMPfigure \else \@EA\let\@EA\MPwrite\csname\@@MPG\@@MPG\MPgraphicfile\endcsname \fi \ifdone \immediate\openout\MPwrite\MPgraphicfile.mp\relax \ifx\MPinputtranslation\empty\else \immediate\write\MPwrite{\MPinputtranslation}% \immediate\write\MPwrite{verbatimtex \MPinputtranslation etex ;}% \fi \immediate\write\MPwrite{\letterpercent\space #2 graphics of job "\jobname"}% \writeMPgraph \setMPrandomseed \fi} \protect \starttext \dorecurse{16}{\startstaticMPfigure{\recurselevel} fill fullcircle scaled 1cm withcolor red; \stopstaticMPfigure} \stoptext ======================== cut here ======================== As a diff: ======================== cut here ======================== --- a/supp-mps.tex 2006-07-22 11:26:47.000000000 -0400 +++ b/supp-mps.tex 2006-09-24 15:32:19.000000000 -0400 @@ -315,7 +315,9 @@ %D setting the next boolean to true. \newwrite\MPwrite +\newwrite\MPstaticwrite +\newif\ifinstaticMPfigure \newif\iflongMPlines \longMPlinestrue % we now have \obeyMPlines \ifx \overlaywidth \undefined \def \overlaywidth {4cm} \fi @@ -720,12 +722,20 @@ \@EA\ifx\csname\@@MPG\@@MPG\MPgraphicfile\endcsname\relax %\donetrue \@EA\newwrite\csname\@@MPG\@@MPG\MPgraphicfile\endcsname % for the sake of plain usage - \donetrue \@EA\@EA\csname newwrite\endcsname\csname\@@MPG\@@MPG\MPgraphicfile\endcsname + \donetrue + \ifinstaticMPfigure + \let\MPwrite\MPstaticwrite + \else + \@EA\@EA\csname newwrite\endcsname\csname\@@MPG\@@MPG\MPgraphicfile\endcsname + \fi \doglobal\addtocommalist\MPgraphicfile\MPgraphicfiles \else \ifcase#1\relax\donefalse\else\donetrue\fi \fi - \@EA\let\@EA\MPwrite\csname\@@MPG\@@MPG\MPgraphicfile\endcsname + \ifinstaticMPfigure + \else + \@EA\let\@EA\MPwrite\csname\@@MPG\@@MPG\MPgraphicfile\endcsname + \fi \ifdone \immediate\openout\MPwrite\MPgraphicfile.mp\relax \ifx\MPinputtranslation\empty\else @@ -1983,6 +1993,7 @@ \long\def\startstaticMPgraphic#1#2\stopstaticMPgraphic {\bgroup + \instaticMPfiguretrue % value is restored by the \egroup \setMPrandomseedfalse \def\MPgraphicfile{#1}% no \jobname here \let\allocateMPslot \gobbleoneargument ======================== cut here ======================== Which has left a minor puzzle.
