mptopdf TeX text problem
by Martin Bruchanov 01 Dec '11

01 Dec '11

Hello, what is the proper way of using MetaPost with TeX text? I have two examples: beginfig(1); draw unitsquare scaled(1cm); draw textext("$\pi$") shifted((0.5,0.5)*cm); % label(btex $\pi$ etex, origin); endfig; end mptopdf --metafun produces only "unknown" where the Pi symbol should be and when I uncomment label the following problem occurs: Output written on test-temp.dvi (2 pages, 256 bytes). Transcript written on test-temp.log. TeXExec | runtime: 0.16436 This is MetaPost, version 1.504 (kpathsea version 6.0.0) mpost: Not writing to .log (openout_any = p). ! I can't write on file `.log'. Please type another transcript file name: ... !pdfTeX error: pdftex (file lmmi12): Font lmmi12 at 600 not found ==> Fatal error occurred, no output PDF file produced! MPtoPDF 1.4.1 : error while processing tex file ----------------------------------------------- But, when I put source in \startMPpage draw unitsquare scaled(1cm); draw textext("$\pi$") shifted((0.5,0.5)*cm); label(btex $\pi$ etex, origin); \stopMPpage and call context, the output PDF is okay. So what is proper way to use TeX inside mpost nowaday?

Splitting natural tables
by Christian 30 Nov '11

30 Nov '11

Hello, is it still not possible to split a table so that it covers one half page an then another half page? It is my understanding that splitting moves the table to the next page and then splits it to the following if it gets too long for one entire page. Would a "manual split" be possible? Examle (table is not split, but could be): \starttext \dorecurse{2}{\input knuth } \startplacetable[title={My Table}] \bTABLE[option=stretch,split=repeat] \bTABLEhead \bTR \bTH C1 \eTH \bTH C2 \eTH \eTR \eTABLEhead \bTABLEbody \dorecurse{20}{\bTR \bTD text \eTD \bTD text \eTD \eTR} \eTABLEbody \eTABLE \stopplacetable \input knuth \stoptext

Math in metapost
by Hans van der Meer 30 Nov '11

30 Nov '11

I would like to put some math in metapost pictures. For the moment I am using textext for the typesetting in my metapost macro: pic := textext("\setbox0=\hbox{\color["&textcolor&"]"&labeltext&"}\dp0=0pt\box0"); picture pic will be placed in the metapost figure. Simple math like $p=2$ works fine, but the system chokes on something like the following matrix: $\pmatrix{p_{0|0}\cr}$ (it does fine in ConTeXt itself). The error is: ! Only one # is allowed per tab. system > tex > error on line 6 in file Info/kanaalmatrix.tex: Only one # is allowed per tab ... Perhaps I am too optimistic about textext's possibilities. But how can I accomplish the placement of these and more elaborate formulae in metapost pictures using ConTeXt? It is of the essence for a series of Powerpoint slides I am preparing, wheein these formulae must be placed as individual pictures. Hans van der Meer

Export to epub
by Keith McKay 30 Nov '11

30 Nov '11

Hi I've been playing about with Export in Context with a view to producing ePubs. When I run the script: /mtxrun --script epub --make test.specification /the test.tree is prepared but no epub file. The output shown below has a couple or 'error' messages which are probably due to the way my text editor is set up (Scite Version 2.02). If anyone is using Scite and producing ePubs I be grateful for some hints on how to set this up so that inkscape and zip works. %%Script Output mtx-epub | creating paths in tree test.tree mtx-epub | copying toc.ncx to test.tree/OPS/toc.ncx mtx-epub | copying test-styles.css to test.tree/OPS/test-styles.css mtx-epub | copying test-images.css to test.tree/OPS/test-images.css mtx-epub | copying test.css to test.tree/OPS/test.css mtx-epub | copying test.xhtml to test.tree/OPS/test.xhtml mtx-epub | running command 'inkscape --export-plain-svg=cow.svg cow.pdf' 'inkscape' is not recognized as an internal or external command, operable program or batch file. mtx-epub | copying cow.svg to test.tree/OPS/cow.svg mtx-epub | copying hacker.jpg to test.tree/OPS/hacker.jpg mtx-epub | copying mill.png to test.tree/OPS/mill.png mtx-epub | creating archive 'zip' is not recognized as an internal or external command, operable program or batch file.

page number in margin
by Henning Hraban Ramm 30 Nov '11

30 Nov '11

Hi again, I’d like to get my page numbers in the margin. This works: \setuppagenumbering[alternative=doublesided,location=margin] But that way it’s on the bottom of the footer margin; I'd like it on the top. Second variant: Even better, I’d like my page number at the bottom of the text margin. How can I achieve that? location option "marginedge" doesn’t seem to do anything, as far as i can tell, and "inright" is the same as "margin". Greetlings from Lake Constance!

TeX Output
by Martin Fechner 30 Nov '11

30 Nov '11

Hi all, in my project I use an environment with lua-code, xml-setups and some other definitions and settings. Is there an simple way to get an output of the TeX-Stream, which will be used to generate the PDF? So it would be possible to manipulate some TeX-parts manually where the PDF-output have some errors or isn't as expected. Best Regards, Martin

Footnote rule is not drawn in columnset layout
by Peter Park Nelson 29 Nov '11

29 Nov '11

In my new 2-column columnset layout, the rule above the footnotes is not appearing. I found an old question in the list archive dealing with a similar problem ( http://archive.contextgarden.net/message/20050626.123839.5318050e.en.html) but the relevant code has been changed since then. Is there a problem with my setup (excerpt) below? %%---------------------------------------------------------------------------%% \definecolumnset[body][n=2,distance=2em,balance=yes] % Use superior figures from the font for footnote marks, instead of \high: \defineconversion[supnumbers][\setff{sups}] % Just create space for the footnote number at the bottom of the column: \def\myfootnotecommand#1{\hbox to 1.5em{#1}} \setupnote[footnote] [location=page, numberconversion=supnumbers, numbercommand=, textcommand=, way=bytext, rule=on, align={hanging,hz}, command=\myfootnotecommand] \setupnotedefinition[footnote] [location=left] %%---------------------------------------------------------------------------------%% Thanks, PPN -- Peter Park Nelson peter.park.nelson(a)gmail.com

context terminal now in gnuplot's CVS
by Mojca Miklavec 29 Nov '11

29 Nov '11

Hello, After 5 years (actually almost 6 - the first t-gnuplot.tex code has been sent to me by Peter Münster on 2nd January 2006) gnuplot developers finally included context terminal into their CVS repository today. (temporary link, but probably slightly more clear than linking to CVS repository) https://github.com/gnuplot/gnuplot-new/commit/62737451bb138f0e679b5a57e0042… The release of gnuplot 4.4.4 was initially planned for around October, which means that it should probably be out sometime soon. Documentation: https://github.com/mojca/context-gnuplot/tree/master/texmf/doc/context/thir… Mojca PS: There are still three pending issues in the area that is rarely used anyway: - I need to fix font switching (I'm currently using \sometxt[gp][iwona,20]{some label} which doesn't work in MKIV and is an ugly hack in MKII) - there are some problems with (draw) externalfigure inside metapost drawings; I might create an abstract layer around that - transparent inline bitmap images don't work and they don't work in MKII at all (partially due to limitations in metapost)

Columnsets: bug in current beta?
by Peter Park Nelson 29 Nov '11

29 Nov '11

Hello, Following the example in the Columns manual, the following works with TeXLive 2011 but not with the current context suite beta (25 nov 2011): \definecolumnset[body][n=2] \definecolumnsethsize{body}{1}{1}\One \definecolumnsethsize{body}{1}{2}\Two \starttext \startcolumnset[body] \dorecurse{5}{\input tufte\par} \startbuffer \placefigure[btlr]{A placeholder figure.}{\externalfigure[widefigure][width=\Two]} \stopbuffer \dorecurse{5}{\input tufte\par} \getbuffer \stopcolumnset \stoptext Using the current beta, the figure only cleanly spans one column -- vertical space for the graphic and caption is reserved in one column; in the other column, text flows on beneath the graphic, which is superimposed. Using TeXLive 2011, the wide figure spans both columns correctly. Thanks, PPN -- Peter Park Nelson peter.park.nelson(a)gmail.com
