Re: [NTG-context] MetaPost Animations

Dear Wolfgang, Thank you for the explanation and the correction of the code. It works nicely. It also taught me some other things too. I'd like to ask you one more thing. When you update the animation module, would you please concern the location of the menu? I think that it is better to put it at the bottom center of the animation frame in default? Currently, it is located slightly left from the center. Thanks again. Best regards, Dalyoung

no bibliography when using bodymatter/backmatter/...
by Andreas Mang 04 Jan '13

04 Jan '13

Hi there, after updating I have spotted serious flaws in my layout. Spending some time in the wonderful garden I could fix most issues. However, I might still be doing something wrong: My TOC and the bib entries were gone. I could reanimate the TOC for the bodymatter, but not for the remaining parts of my document. Secondly, the bibliography is still missing. I have attached a minimal example to demonstrate my problems. I am probably missing flags / settings. My problems are: 1) The section title "Backmatter" does not appear in the TOC. 2) the bibliography does not appear nor is the citation added (this is different, if I put the placepublication command into the bodymatter) Cheers, Andreas % ConTeXt ver: 2013.01.02 18:19 MKIV %%% minimal example %%% \setupcombinedlist[content][level=4, alternative=c] \startsectionblockenvironment[bodypart] \setupuserpagenumber[numberconversion=numbers] \setuppagenumber[number=1] \stopsectionblockenvironment \startsectionblockenvironment[backpart] \setupuserpagenumber[numberconversion=numbers] \stopsectionblockenvironment \usemodule[bib] \usemodule[bibltx] \setupbibtex[database=sample] \setuppublications[numbering=yes] \starttext \placecontent[criterum all] \startbodymatter \section{Bodymatter} % this heading does not appear in the TOC \ConTeXt \cite[hh2010a] \stopbodymatter \startbackmatter \section{Backmatter} \placepublications[criterium=text] \stopbackmatter \stoptext %%% minimal example %%%

\placefigure[margin] but in left margin?
by Mikael P. Sundqvist 03 Jan '13

03 Jan '13

Dear list, I want to have the effect I get with \placefigure[margin] but I want it _always_ in the left margin instead of the right margin where it ends up by default. I have tried several other keys but with leftmargin, inleft the figure is not put in the top of the page, "independent of the text". Can I fix this with some setup? Small test file: \starttext \input tufte \placefigure[leftmargin][none]{With the key leftmargin}{\externalfigure[cow][width=1cm]} \input tufte \placefigure[inleft][none]{With the key inleft}{\externalfigure[cow][width=1cm]} \input tufte \placefigure[margin][none]{With the key margin}{\externalfigure[cow][width=1cm]} \input tufte % This is the way I want it, but I want it in the left margin instead \stoptext

[***SPAM***] Empty line, but not at the top of a page.
by "H. Özoguz" 03 Jan '13

Hi together and happy new year, with \crlf one can force a empty line. But this empty line should not be printed, if it is on the top/start of a new page, so a new page should not begin with an empty line. Which is the correct command for that? Regards, Huseyin

\savebuffer
by Wolfgang Schuster 03 Jan '13

03 Jan '13

Hi Hans, can you add a \savebuffer variant which works like the first version of the command where \savebuffer[<buffername>][<filename>] saved the buffer as <filename> and not as \jobname-<filename>.tmp like it currently does. Instead of a new command a key-val-version of \savebuffer would do the job as well, e.g. \savebuffer[list=<buffername>,file=<filename>,prefix=no] or something similar. Wolfgang

problems with letter module
by Wolfgang Werners-Lucchini 02 Jan '13

02 Jan '13

Hallo, I have updated context and the letter module to ConTeXt ver: 2012.12.06 22:36 MKIV fmt: 2012.12.8 int: english/english Problem: My letters do not work anymore. I have found that \setlettervalue{tax}[Steuer]{xxx} is one of the problems. I have to use \setupletter[tax=xxx] instead. I have to lock for then tax renaming. Now the letter is compiling, but it is completly broken. In the log I have found a lot of lines setup > error in line 20, namespace "553", instance "letter", key "frame" setup > error in line 58, namespace "539", instance "letter", key "invoice" setup > error in line 58, namespace "539", instance "letter", key "date" setup > error in line 58, namespace "539", instance "letter", key "phone" setup > error in line 58, namespace "539", instance "letter", key "tax" I have the impression, that there has a lot changed. How can I fix this temporary? (I have to write my letter NOW!) Wolfgang

Re: [NTG-context] MetaPost Animations

Dear Wolfgang, Thank you for the explanation, and your sample works nicely. I enclosed \processMPbuffer using \startframe and \stopframe as following. Then I got a 'undefined control sequence' error. If I use '\framed[]' instead of '\startframe … \stopframe', then it gave all 7 circles of different radius in two pages without error. If I add "\startanimation … \stopanimation", the only change is the appearance of menu at the bottom of the last circle.(no animation) What is wrong in the code?

Dear Troy, The animations are impressive and thank you for sharing the code. In the creation of many pdf for animation, it changes the recurselevel only. I wonder if there is a way to make such kind of animation in ConTeXt using Wolfgang's animation module. Then we can include the animation in PDF output directly. Here is my trial.

XeTeX, ConTeXt and font/filename quote char
by Khaled Hosny 29 Dec '12

29 Dec '12

Hi all, Some people have been complaining that it is not possible to use XeTeX with filenames containing parenthesis because XeTeX treats it as filename quote char and this it gets stripped. Anyway, after some searching it turned out this was added in 2004 for ConTeXt to workaround some MetaPost quotation issue[1]. Now I'm not sure if this is still needed/used by ConTeXt and was wondering if it can be dropped now? Regards, Khaled [1] http://tug.org/pipermail/xetex/2004-October/001215.html

References_to_footnotes in index
by Robert Blackstone 27 Dec '12

27 Dec '12

Dear List, The book that I am working on has an index of authors. On some pages of the book an author's name only occurs in a footnote. Is it possible in ConTeXt to mark, in the index, those occurrences in footnotes so that in these cases not only the page number appears in the index but also, preferably as superscript, the footnote number on that page? As for example Arnold, Franck Th. 9, 283 indicating footnote 3 on page 28 (Sorry, I cannot make a superscript in this mail editor) What I certainly don't want is separate index entries for those authors. Each author name should occur in the index only once. Thanks in advance of any help. Best regards, Robert Blackstone
