random background picture in metafun
by Thomas A. Schmitz 15 Mar '12

15 Mar '12

Hi all, scenario: for a presentation, I want the background to be a random picture, taken from a directory "backgroundpics." The pictures are numbered consecutively as 1.jpg through 22.jpg. For some complex reasons, it would be easier for me to include these pictures via metafun (I want to add other graphical elements on top). So my question is, how can I pick a random picture? Given the code StartPage ; draw externalfigure "backgoundpics/1" xscaled PaperWidth yscaled PaperHeight ; StopPage ; how can I obtain a random number and make metapost pick the corresponding picture? Sorry, difficult to make a minimal example here... Thomas

Bug in \setuplist
by Willi Egger 15 Mar '12

15 Mar '12

Hi Guru's While typesetting an old book (original is from 1853) I need to tweak the table of contents. It looks as follows: CHAPTER II. BEES CAPABLE OF DOMESTICATION. Astonishment of persons at their tameness, 25. Bees intended for the comfort of man. Properties fitting them for domestication. Bees never attack when filled with honey, 26. .... I have attached a minimal example which works in Context version 2011.07.19 but not in 2012.01.25 nor in todays beta. Compilation stops with an error complaining that the \MycommandA has an extra }. Further there is the question how to get roman numerals when using the \Mycommand. - I realize, that all optional keys are ignored at the moment that the alternative=command is used. Kind regards Willi

Footnotes in formulas
by Procházka Lukáš Ing. - Pontex s. r. o. 15 Mar '12

15 Mar '12

Hello, what is the good way how to use footnotes in formulas? This code lowers the "Bbb" text: ---- \starttext \startformula Aaa\footnote{Some footnote text} \qquad Bbb \stopformula \stoptext ---- Example 2: ---- \starttext \startformula Ccc{\footnote{Footnote C}} \qquad Aaa\footnote{Some footnote text} \qquad Bbb \stopformula \stoptext ---- In this case, the footnote after "Ccc" doesn't lower next text; but "Footnote C" is not listed in the bottom of the page (?). So - how to add a footnote to formula scope? Or to avoid it? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Styling of naturaltable headings
by Steffen Fritzsche 15 Mar '12

15 Mar '12

Hi, using the latest beta I have the following problem styling my table headings based on the naturaltables module. My test document looks as follows \setupTABLE[frame=off,option=stretch] \setupTABLE[c][each][style=\ss] % Styling 1 \setupTABLE[r][first][style={\ss},bottomframe=on] % Styling 2 \starttext \placetable [here][tab:example] {A very simple example of a table.}{ \bTABLE \bTABLEhead \bTR \bTH col1 \eTH \bTH col2 \eTH \eTR \eTABLEhead \bTABLEbody \bTR \bTC this \eTC \bTC is \eTC \eTR \bTR \bTC a \eTC \bTC table \eTC \eTR \eTABLEbody \eTABLE } \stoptext Neither the line marked "Styling 1" nor the line marked "Styling 2" do switch to a sans serif font in the table head. "Styling 1" does this correctly for the table body but not for the head. Any ideas how I might get an sans serif font in my table heading? Thanks! Steffen

Hello, I have problem using \definetabletemplate (http://wiki.contextgarden.net/Command/definetabletemplate, http://www.mail-archive.com/search?l=ntg-context%40ntg.nl&q=definetabletemp…) The following code doesn't work: ---- \definetabletemplate[Test][|c|] \starttext \starttable[|c|] % This is OK \HL \NC aaa \AR \HL \stoptable \starttable[Test] % A problem (?) \HL \NC aaa \AR \HL \stoptable \stoptext ---- What am I doing wrong? Another question - is there a better way to define table template? Like \definetable[TestTab][|c|] (or \setuptable...) and later \startTestTab ... \stopTestTab? TIA. Best regards, Lukas -- Ing.

xml tree extension?
by Meer, H. van der 14 Mar '12

14 Mar '12

Is it possible to have the following order of actions? <root> <file name="filename1"> <file name="filename2"> .. </root> The file contains an xml-tree starting at <fileroot>.. At the moment I am processing the files with \xmlprocessfile{fileroot}{filename}{}, but this generate separate node-lists for <root> and <fileroot>; at least, that is my understanding of its workings. Can I change the processing in such a way that something akin the following tree structure is processed, each time with a new file: <root> <file name="filename1"/> <fileroot> .. </fileroot> <file name="filename2"/> <fileroot> .. </fileroot> .. </root> Or is it impossible to accomplish?

\attributedef not working?
by Meer, H. van der 14 Mar '12

14 Mar '12

Processing xml I get with: \writestatus{************}{\xmlattributedef{#1}{.}{default}{???}} output: ************ > ??? and \writestatus{************}{\xmlattribute{#1}{.}{default}} has no attribute output but with: \writestatus{************}{\xmlattdef{#1}{default}{???}} output: ************ > mydefault Is something amiss with \xmlattribute and \xmlattributedef? I need these in order to get an attribute from a node higher up in the xml-tree. Hans van der Meer

Format creation with luatex
by Marco 14 Mar '12

14 Mar '12

Hi, I fail to create a format with luatex. I followed Hans' instructions¹ from TUG 2009. Example: % file fmt-plain.tex \input plain \directlua {tex.enableprimitives('', tex.extraprimitives())} \pdfoutput=1 \everyjob \expandafter {% \the\everyjob \input luatex-basics\relax \input luatex-fonts\relax \input luatex-mplib\relax } \edef\fmtversion{\fmtversion+luatex} The format generation stops with a star (*). $ luatex --ini fmt-plain.tex This is LuaTeX, Version beta-0.70.1-2011051918 (rev 4277) (INITEX) \write18 enabled. (./fmt-plain.tex (/home/marco/bin/context-beta/tex/texmf/tex/plain/base/plain.tex Preloading the plain format: codes, registers, parameters, fonts, more fonts, macros, math definitions, output routines, hyphenation (/home/marco/bin/context-beta/tex/texmf/tex/generic/hyphen/hyphen.tex))) * Any help appreciated.
