How to increment a counter
by Otared Kavian 07 Feb '15

07 Feb '15

Hi all, I have a counter in an itemize environment which I need to increment by using \incrementcounter[NameOfTheCounter] However this does not work in the following example, maybe due to the use of blocks, or some other reason. I define two blocks, one for exercises, one for the solutions. Then in each exercise I have a certain number of questions, presented with an itemgroup named Questions. Analogously I have an itemgroup named Answers, which appear in the solution to an exercise. Now my problem is that some questions don’t have an answer included (for instance they are too easy…) and I need to increment the counter by saying \incrementcounter[Answers] But this does not work, for an unknown reason. (See below) Can anyone give an advice? Thanks in advance. Best regards: OK %%%% begin question-answers-block.tex \defineblock[Exoblock] \defineblock[Solblock] \defineenumeration[exo] [alternative=hanging, width=fit, text=Exercise, stopper={.}, before=, after=\blank] \defineenumeration[solution] [alternative=hanging, width=fit, text=Solution of exercise, stopper={.}, before=, after=\blank] \defineitemgroup[Questions] \defineitemgroup[Answers] \defineconversion[Questions][\numbers] \defineconversion[Answers][\numbers] \setupitemgroup[Questions][style=bold, width=1.5em, packed, alternative=hanging, stopper=, right=)] \setupitemgroup[Questions][n] \setupitemgroup[Answers][style=bold, width=1.5em, packed, alternative=hanging, stopper=, right=)] \setupitemgroup[Answers][n] \hideblocks[Exoblock] \hideblocks[Solblock] \starttext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \beginExoblock \startexo Solve the following problems. \startQuestions \startitem This is Question 1 of exercise 1. \stopitem \startitem This is Question 2 of exercise 1. \stopitem \startitem This is Question 3 of exercise 1.

Setup for appendices: a bunch of questions
by Mojca Miklavec 06 Feb '15

06 Feb '15

Hello, I need a tiny bit of help with properly setting up the appendices. 1.) I would like to include both chapters and titles. Is this the proper way to go? (It took me a while to figure out how to include the titles at all.) \setuphead [title] [incrementnumber=list] \placelist [title,chapter,section] [criterium=all,alternative=c] But why is there less space in front of a \title{...} in TOC than in front of a \chapter{...}? 2.) How can I define a different width for appendices in TOC (to reserve enough space for the word "Appendix")? I use \setuplist [section] [width=10mm,numberstyle=\os\bf,pagestyle=\os,label=yes] but I would like to use "width=27mm" for sections inside \startappendices ... \stopappendices than for regular sections. Is there any workaround? 3.) For appendices I want to set \setuphead [chapter] [number=no] \setuphead [section] [page=yes,sectionsegments=section,conversion=Character,sectionstopper=:] without affecting regular sections and chapters. Is it possible to do this on top of the document (or in the layout) as opposed to changing the settings just before appendices start? I would like to avoid messing up with such settings in the middle of the document. I tried to play with \defineconversionset and \setupsectionblock [appendix] [sectionconversionset=...] but I'm unable to understand how these commands work exactly. A minimum working example (yes, in MKIV) is attached. If anything could/should be improved, please also let me know. Thank you, Mojca

How to use \setuplist for formatting a chapter entry?
by Rob Heusdens 06 Feb '15

06 Feb '15

Hello list, I have one little problem that I need to solve to finish my work on a document. I want to format a list entry for the TOC for chapters like this: "Hoofdstuk #1 -- #2 . . . . . . . . #3" Where #1 is the chapter number, #2 is the title and #3 the page number where the chapter begins. Of course the ". . . " entry is just like the normal cases where the dots fill the rest of the line. I have an *almost* correct solution using numbercommand and setting the width for the title, but this leaves a gap between the formatted chapter number and the title, because "chapter 9" and "chapter 10" don't take the same width. So, some other solution is needed. I tried using the command option, which needs 3 arguments, but could not get it to work. Here is how it looks now: \define[1]\ChapterNumberToc% {Hoofdstuk #1 -- } \definecombinedlist[content][chapter] \setupcombinedlist[content][level=4, alternative=c] \setuplist[chapter][headnumber=yes,style=bold,width=8em,numbercommand=\ChapterNumberToc] \starttext \completecontent \dorecurse{5}{ \chapter {Knuth} \input knuth \chapter {Zapf} \input zapf} \stoptext As you can see, there is a different between the 9-th and 10-th chapter, because title is set at a specific width, and doesn't adapt to the width of the formatted chapter number entry. How to solve this, so that the title is placed directly after the "Hoofdstuk #1 -- " entry, thereafter the filler with dots and finally the page number at the location where it is now. Thanks, Rob

intermezzo/sidebarswith rounded corners.
by John Culleton 06 Feb '15

Client has an existing book that I am redoing with many inserted square boxes of text slightly protruding in the margin. Main text wraps around each box. The line around each such box has rounded corners. Is there an example somewhere in the manuals or elsewhere? -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html Updated PDF e-book: "Create Book Covers with Scribus 1.4.5" coming soon at http://www.booklocker.com/!

Hi guys, The harddisk of the server that (amongst other things) runs the ConTeXt wiki and various luatex.org websites has apparently crashed. We are trying to get the server running again, but it could take some time before everything is back online. Best wishes, Taco

Re: [NTG-context] A note on Arabic names in bibliographies and indices
by Alan BRASLAU 02 Feb '15

Of course, language of the cited publication. Nothing else makes sense at all. This field is also to be used for hyphenation of the title field. BUT, the author of the TeX document must control and decide if the bibliography will use an eventual language= field or rather use the language rule in vigor for the TeX document; alternately, he/she could impose a particular language for the rendering of a particular dataset. Thomas has argued this point. The explicit parsing of "vons" or particles gives control for the sorting of author names. It is not so complicated: if treated as a particle or von, it does not enter into the sorting; if treated as intimately part of the surname (often, but not always, the case for post-revolution names in French, for example) then it does enter into the sorting. German is the only case that I know where the "von" gets placed after the first names. Here, one must not abbreviate the von, of course, as in: "Laue, M. V." - and I have seen this published!! Nor do I want to see: "von Laue, M." However, to be correct, some publications might appear as "Laue, M." Now, say that I want to cite Laue's work published in English (as well as one or more of his references published in German). Clearly this real case will cause grief. I could set language=german for all of his work, but then how are the titles to be hyphenated (and what about quotation marks if the style uses them)? This is why Hans asks if we should optionally parse 5 part author names. Here is a real case: @Article{Friedrich1912, Title = {Interferenzerscheinungen bei Röntgenstrahlen}, Author = {Friedrich, W. and Knipping, P. and Laue, M. von}, Journal = {Sitzber. Math-phys. Kl. bayer. Akad. Wiss. Manche}, Year = {1912}, Pages = {303}, Volume = {22}, Language = {german} } @Article{Friedrich1913, Title = {Interferenzerscheinungen bei Röntgenstrahlen}, Author = {Friedrich, W. and Knipping, P. and Laue, M.}, Journal = {Annalen der Physik}, Year = {1913}, Number = {10}, Pages = {971–988}, Volume = {346}, Doi = {10.1002/andp.19133461004}, ISSN = {1521-3889}, Language = {german}, Publisher = {WILEY-VCH Verlag}, } @Article{Friedrich1913a, Title = {Phénomènes d'interférence des rayons de Röntgen}, Author = {Friedrich, W. and Knipping, P. and Laue, M.}, Journal = {Radium (Paris)}, Year = {1913}, Number = {2}, Pages = {47–57}, Volume = {10}, Language = {french} } @article{PhysRev.37.53, title = {The Diffraction of an Electron-Wave at a Single Layer of Atoms}, author = {Laue, M. v.}, journal = {Phys. Rev.}, volume = {37}, issue = {1}, pages = {53--59}, numpages = {0}, year = {1931}, month = {Jan}, publisher = {American Physical Society}, doi = {10.1103/PhysRev.37.53}, url = {http://link.aps.org/doi/10.1103/PhysRev.37.53} } This last case is directly what I download from: http://journals.aps.org/pr/abstract/10.1103/PhysRev.37.53 Yikes!

font search path and subfolders
by Jörg Weger 02 Feb '15

02 Feb '15

In my Linux home folder I have the usual “~/.fonts/” folder in which I have put subfolders “~/.fonts/opentype/” and “~/.fonts/truetype/”. Inside those subfolders I would like font families to have their own subfolders. When I set the font search path by running export OSFONTDIR="/usr/local/share/fonts;$HOME/.fonts/opentype;$HOME/.fonts/truetype" from the command line followed by mtxrun --script fonts --reload only the fonts in the /truetype/ subfolders are recognised. This means I have to put all my opentype fonts directly into the /opentype/ folder. On Stackexchange I found a solution http://tex.stackexchange.com/questions/209705/context-system-font-search-pa… which says that putting “//” after the folder made the search recursive, but neither export OSFONTDIR="/usr/local/share/fonts//;$HOME/.fonts/opentype//;$HOME/.fonts/truetype//" nor export OSFONTDIR="/usr/local/share/fonts//;$HOME/.fonts//" works for me. What am I missing? (Typo maybe?) Being able to put opentype font families into subfolders as well would be a great help to keep a clear view of all my fonts. Greetings Jörg

Grey background for pages belonging to last section of every chapter
by Rob Heusdens 02 Feb '15

02 Feb '15

Hello list, For the last section of every chapter I want a grey background for the text, which otherwise should look the same as every other section, except that it starts on a new page (I can set that by defining my own section command). The last section summarizes the chapter. My current implementation is using a frame: \defineframed[achtergrond] [frame=off, background=color, backgroundcolor=gray, width=fit, height=fit, offset=2ex, align={flushleft,nothyphenated,verytolerant}] And use it as: \achtergrond{ \section{Last section} \startitemize[n] \item ... \stopitemize } But this does not accomodate sections longer then a page. And I can't place \page command in the middle of an itemize, and using \stopitemize, \startitemize[continue] makes the pages vary in sizes. Is there some way to achieve the desired effect (grey background behind the text, and otherwise page layour identical to other sections) without the problem that text exceeds the page size? Greetings, Rob PS. The defined frame is also used elsewhere, but the last section should in fact not have normal alignment like the other sections.
