report: non-stretchable spaces after periods
by Alan Bowen 08 Dec '08

08 Dec '08

In a message some time ago, Wolfgang suggested that \def\ {\thinspace} would serve to get non-expanding or non-stretchable spaces after periods that occur within sentences and in bibliographies. When I discovered that, while this worked well in limited contexts, in a lengthy bibliography which relied on the period as the main form of punctuation it lead quickly to numerous line-breaking problems. So Wolfgang has now has kindly proposed \def\ {\hskip.1666em\relax} since \hskip is a TeX primitve and mentioned in every (plain) TeX manual. And I gratefully confirm that this works very well. Alan

Sorting references
by Jean Magnan de Bornier 08 Dec '08

08 Dec '08

Hi all, Using the bib module, I want my references to be sorted alphabetically; if I understood correctly the doc: \setuppublications[alternative=apa-fr,sorttype=bbl,criterium=cite] Then the alphabetical order is taken from the bibtex *keys*, and it doesn't always follows true alphabetical order... :-( And it seems that with bbl the whole bbl content is necessarily written in references. How can I do to have only cited material included in references? TIA, -- Jean

question about rulethickness
by Jelle Huisman 08 Dec '08

08 Dec '08

Hi all, It looks like rulethickness can only be applied to all 4 sides of a cell all at once, or is there a way to specify the thickness of left|right|top|bottom? As the example shows I get a thicker frame around the 2 rows, but I want to use the normal frame thickness inside the cells. \starttext \setupTABLE[r][1,2][rulethickness=1pt] \bTABLE \bTR\bTD[nc=3] long text \eTD\eTR \bTR\bTD text \eTD\bTD text \eTD\bTD text \eTD\eTR \bTR\bTD even \eTD\bTD more \eTD\bTD text \eTD\eTR \eTABLE \stoptext Thanks, Jelle

Dangling lines.
by Bart C. Wise 08 Dec '08

08 Dec '08

I created an Author's note (code below). It is designed to print out a note, skip a line, and then follow with the Author's signature. The problem I'm having is that ConTeXt will break the page just before the author's signature leaving it dangling on the next page. If I use a \vbox, that has problems when the notes need to go more than the current page. How do I fix the code below? \definestartstop[AuthorNote][ before={ \bgroup \startnarrower \switchtobodyfont[10pt] }, after={ \vskip-0.2ex Author \stopnarrower \egroup \blank \noindentation }, ] Thanks, Bart

How to get the total page number at startup in luatex?
by Zhichu Chen 08 Dec '08

08 Dec '08

Hi, I've met a weird thing, I can't get \totalnumberofpages in the preamble. But it used to work. A simple test file is ++++++++++++++++++++++++++++++++++ \dorecurse{\totalnumberofpages}{\setvalue{test::\recurselevel}{:\recurselevel:}} \def\test{\getvalue{test::\pagenumber}} \starttext \input knuth \page[yes] \input knuth \page[yes] This should be \quotation{:\pagenumber:}, but it's \quotation{\test} \stoptext ++++++++++++++++++++++++++++++++++++ Any suggestions about how to do that? I wanna define each page a macro. -- Best Regards Chen ---------------------------------------------------------------- Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.

calling a function with complex parameters
by Michail Vidiassov 08 Dec '08

08 Dec '08

Dear All, I need to fill a lua table with data, and some values may be tables. How to supply that data from ConTeXt? The most straightforward way is to make user fill a string with lua code of table initiaiser and then use "loadstring". In this case the syntax is laconic, but resilence in case of errors is zero. The other way is to have the user to call series of functions, building the complex structure from ground up by making basic stuctures and adding them to final structure one by one. In this case the passed parameters can be scrutinized for correctness, but multiple calls like "addsmthtosmth", "setsmthinsmth" will make the result uneasy to read, to say nothing of writing. What is considered kosher in ConTeXt? Where can I found examples? Sincerely, Michail PS. data that has to be passed to function will look like (example is not lua): -------------- name = "3D surface"; toolbar = TRUE; // display 3D toolbar tree = TRUE; // display model tree views = ( { name = "DefaultView"; // first view (default) projection = { perspective = TRUE; // Perspective projection aac = 2.5; // View angle }; camera = { // Camera position, see movie15 manual for explaination coo = [ 0, 0, 0 ]; // Center of orbit - where the camera are pointed to c2c = [ 0, 0, 1 ]; // vector from coo directed to camera rot = [40, 0,60 ]; // rotatations of vector from coo directed to camera around Ox, Oy, Oz roo = 50; // distance from coo to camera roll = 0; // camera rotation angle }; bg = [ 1.0, 1.0, 1.0 ]; // Background color lights = "CAD"; // Lighting scheme nodes = ( ( "xlabel", 1.0, TRUE ), ( "ylabel", 1.0, TRUE ), ("Small box", 1.0, TRUE) ); }, { name = "CrossView"; // view with a crossection projection = { perspective = TRUE; // Perspective projection aac = 2.5; // View angle }; camera = { // Camera position, see movie15 manual for explaination coo = [ 0, 0, 0 ]; // Center of orbit - where the camera are pointed to c2c = [-1,-1, 0 ]; // vector from coo directed to camera roo = 50; // distance from coo to camera roll = 0; // camera rotation angle crossection = { point = [ 0, 0, 0 ]; normal = [ -1, -1, -1 ]; intersection = TRUE; transparent = FALSE; }; bg = [ 1.0, 1.0, 1.0 ]; // Background color lights = "CAD"; // Lighting scheme nodes = ( ( "xlabel", 1.0, TRUE ), ( "ylabel", 1.0, TRUE ), ("Small box", 1.0, TRUE) ); } } --------------

can not include movie
by Michail Vidiassov 08 Dec '08

08 Dec '08

Dear All, ConTeXt user manual says movies are just like figures, but when I process \starttext \placefigure[here]{none}{\externalfigure[demo.mov][width=0.7\textwidth, height=.7\textwidth, label=demo, preview=yes]} \stoptext with context filename.tex using the latest minimals without any custom settings I do not get movie included. What can be wrong? I am a ConTeXt newbie and fail to see any possible place for errors in the above test case. Sincerely, Michail

luatex and javascript
by Zhichu Chen 08 Dec '08

08 Dec '08

Hi, I've searched the list and it seems that no one has been occurred to my problem. Has the javascript interface gone? 'cause I failed the following simplest file: ================================================================ \setupinteraction[state=start] \starttext A few years back, \TEX\ could only produce \fillinfield [dvi] {DVI} output, but nowadays, thanks to \fillinfield {Han The Thanh}, we can also directly produce \fillinfield [pdf] {PDF}! Nice eh? Actually, while the first field module was prototyped in ACROBAT, the current implementation was debugged in \fillinfield [pdfTeX] {\PDFTEX}. Field support in \fillinfield [ConTeXt] {\CONTEXT} is rather advanced and complete and all kind of fields are supported. One can hook in appearances, and validation \fillinfield [JavaScripts] {JAVASCRIPT}'s. Fields can be cloned and copied, where the latter saves some space. By using \fillinfield {objects} when suited, this module saves space anyway. \stoptext ================================================================ It's copied from the mwidget-s.pdf My luatex is 0.30.3, and I just run "luatools --generate" and "ctxtools --update" today.

Important: ConTeXt Minimals and --delete/--keep switch
by Mojca Miklavec 07 Dec '08

07 Dec '08

Hello, This is a rather important notice for users of ConTeXt minimals. You might want to add --keep to ./first-setup.sh There are some options for which I'm not sure if they should be enabled by default or not. The script (mtx-update.lua and consequently the simplistic ./first-setup.sh script) provides two switches: --keep and --delete. The --delete switch deletes all the files that are not part of distribution. The --keep switch doesn't care about those files (that have been remove from distribution or that you added) and leaves them where they are. Your own files should go to texmf-local that update doesn't touch at all. Now the important info: if you want your files to be kept, you should use the --keep switch in ./first-setup.sh. --delete has been misfunctional for a while, and maybe it should not be kept as the default option. But as it stands now, it is the default. Recently there has been a new option added (--extras=list,of,context,modules), but I would like the option to be renamed to something more self-explanatory than --extras= (--modules= for example). You can test if fetching modules works OK, but I would like to rename the option. Mojca (Maybe we should add --cvs-exclude rule to rsync to prevent deleting kpathsea files and formats.)

Hi, a space between the font dimension number and the unit breaks compilation. And before anyone asks... the space was inserted by chance. :) \definefont[FOO] [Sans at 30 pt] % ^ \starttext \FOO Hello world! \stoptext Best wishes, Peter
