Textbackground offset with multi-col paragraphs
by Thomas Floeren 23 Nov '17

23 Nov '17

Hi, I noticed that with one of the recent betas the right offset of my textbackgrounds doesn’t work properly anymore when the textbackground contains a multi-column “paragraph”. A minimal: \defineparagraphs [TestPar][n=2, distance=7mm] \setupparagraphs [TestPar][1][width=2em] \definetextbackground [CB][ location=paragraph, backgroundcolor=gray, leftoffset=.3em, rightoffset=.3em, topoffset=.3em, bottomoffset=.3em, frame=off ] \starttext \starttextbackground [CB] \dorecurse {40} {a b c } \stoptextbackground text \starttextbackground [CB] \startTestPar img \TestPar \dorecurse {40} {a b c } \stopTestPar \stoptextbackground \stoptext The first box is OK and as expected. But with the second one (containing a “paragraph”) the right offset gets miscalculated, so that the text runs into the edge of the background. With a beta from July or so the behavior was still OK. Thanks for any advice, best, -- Tom http://dflect.net/context-typeset-tool/

synctex and TeXShop problem
by Alan Bowen 22 Nov '17

22 Nov '17

With the latest betas, I see that with the TeXShop Engine #!/bin/tcsh # Before using this engine, you must run the following command once in Terminal: luatools --generate set path= ($path /usr/texbin /Users/bowen1/Dropbox/ConTeXt/tex/texmf-osx-64/bin) mtxrun --script context --autogenerate --file-line-error "$1” and \setupsynctex[state=start, method=max] in the source file, the requisite *filename*.synctex auxiliary file is produced on processing. But I am still not getting any linkage between the source file and the preview file, that is, clicking on one does not have any effect on the other. Is there something else that I need? I am running ConTeXt ver: 2017.11.15 with macOS 10.13.1. Alan

Setting the footnote symbol
by Idris Samawi Hamid ادريس سماوي ح امد 17 Nov '17

Der gang, For the following \definefont scenario, the footnote symbol in the main text is not raised: ======= \setuppapersize[letter][letter] % \setupbodyfont[schola,12pt] \definefont[PagellaRegular] [texgyrepagella-regular.otf at 14pt] \definefont[PagellaRegularSmall][texgyrepagella-regular.otf at 12pt] \setupwhitespace[big] \setuplayout[width=4.5in,height=5.5in,backspace=2in] \setupnotation[footnote][style={\PagellaRegularSmall}, % text style of the footnote text numbercommand=\PagellaRegularSmall, % symbol-font style in the footnote titlestyle={\PagellaRegularSmall}] % Why is this necessary? \setupnote [footnote][textcommand={\PagellaRegularSmall}] % symbol-font style in the main text \noheaderandfooterlines \starttext \PagellaRegular \startframedtext[width=4.5in,offset=0pt] \startlocalfootnotes Hence in Met VII, where Aristotle debates with masterly penetration how to meet the claim of substance to be at once universal, intelligible, and definable, and at the same time unique and individual, the singular is at length superseded on the throne of substance by the infima species. \startfootnote Or \quotation{materiate form,} as Aristotle also calls it because it attains existence in a material embodiment and cannot be defined without reference to matter, though matter is itself indefinable. The discussion is interspersed with criticism of the forms. Aristotle attacks the theory as a purely arbitrary individualisation of universals, and the detail of the polemic, as well as the context, suggest that he is attacking Plato not for divorcing infimae species from singulars, but for separating and reifying genera taken apart from species. [\textellipsis] \stopfootnote\ That is to say the genus is taken to be fully actualised in its infimae species, and its further differentiation into singulars is treated as irrelevant. \placelocalfootnotes \stoplocalfootnotes \stopframedtext \stoptext ======= What do we need to do to get a raised footnote symbol in the main text (line 6 of the pdf)? Thanks in advance. Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80512

getting metafun positions within (displayed) math mode
by Sanjoy Mahajan 17 Nov '17

17 Nov '17

Dear ConTeXters, For my sins, and to make students unhappy all over the world, I am writing another book: _A Student's Guide to Newton's Laws of Motion_ (for Cambridge University Press, aka CUP). As partial compensation, I convinced CUP that I may typeset it in ConTeXt and deliver them PDF. Being hopefully a guide actually useful to students, it will annotate every symbol in important equations, a feature cribbed from the first book of the _Student's Guide_ series, Dan Fleisch's _A Student's Guide to Maxwell's Equations_. I've attached an image of what such an annotated equation looks like (from page 2 of Fleisch's book). It's like a labeled part diagram (say, for a laptop), where each part (here, each symbol) is connected with an line to its explanation. I'm trying to do so with a combination of ConTeXt, MetaPost/MetaFun, TikZ, and whatever else might work. But I am a bit stuck at the following spot. My plan is to use MetaFun to get the coordinates of each symbol in a (displayed) equation and then, with MetaFun, connect those symbols to mini-paragraphs of explanation that surround the equation. But I am stuck on how to use \hpos in math mode. I'd like to do something like: \startformula \hpos{n1}{\sum}_{\hpos{n2}{0}}^{\hpos{n3}{1}} \stopformula to get the locations of the nodes n1, n2, and n3 without interfering with the math typesetting -- e.g., the engine should still know that \sum is in display-math mode, so it should be large and have its sub- and super-scripts below and above it, rather than next to it. However, the \hpos hides its argument in an \hbox, and thus hides it from the math layout. Thus, I have to do something like this minimal example: \starttext \startformula \sum_0^1 % what it should look like \quad \hpos{n1}{$\displaystyle\sum$}_{\hpos{n2}{$0$}}^{\hpos{n3}{$1$}} \stopformula \stoptext The hpos'ed version after the \quad looks different, even after the \displaystyle hack. Is there a version of \hpos for math mode? That would be the cleanest solution, because who knows what else would be needed for other cases, even if the limits can be placed correctly. Or is there a better way to annotate equations? (TikZ seems to have the same issue, in that it cannot see into equations.)

Metapost: How to get total number of pages?

Hello, it seems that there is 'PageNumber' variable (macro) available within MP code, maybe introduced by 'StartPage', within MP. How do I get total number of pages or last page number within MP (in Ctx: \totalnumberofpages, \lastpage)? TIA. Best regards, Lukas -- Ing.

Re: [NTG-context] org-mode & ConTeXt
by Jörg Hagmann 16 Nov '17

Hi Gour, I'm using org-mode for almost everything. If I need a pdf-file of, e.g., a subtree, I do the following: 1. Export the subtree as an org-file (the directory, title etc. of the exported file are specified as :PROPERTIES:) 2. I process the exported file with a ruby-script I wrote myself. It does what I need, i.e. very basic things. More complicated stuff can be included in the original org-file, as context-commands, provided they don't bother you. The result is a .tex file. 3. process the tex file with context. I tried Pandoc, but concluded it was easier to concoct something myself.

Re: [NTG-context] framed with titles

Hi, I got a partial solution to suppress the automatic display by changing “text=theorem,” to “text=,” and “number=yes” to “number=no”. But, I couldn’t remove a blank line before the main text. So it is a partial solution. > 1. to put “Theorem #.#” inside the FrameTitle?(#.# means that chapter number.theorem number) > 2. to suppress the automatically display of “Thm #” inside the text? The command \FrameTitle{Theorem \getmarking[chapternumber].\recurselevel} shows “Theorem 1.1”, but the it shows the chapternumber -1 not the real chapternumber. Also I don’t know how to put the theorem counter after chapternumber instead of \recurselevel. Here is a sample code. Thank you for reading.

org-mode & ConTeXt
by Gour 14 Nov '17

14 Nov '17

Hello, I plan to start working on series lectures/presentations for educational purposes and I'm going to use ConTeXt for typesetting the whole material. Considering that for smaller articles (e.g. blog posts) I use Emacs' org-mode (with Hugo static-site-generator) and spend fair amount of time with org-mode, I wonder whether you in general can recommend using org-mode for collecting notes and then export to ConTeXt (via Pandoc)? Another concern - disclaimer: still haven't go through excellent Bibliographies manual - is whether it is possible to e.g. use org-ref (https://github.com/jkitchin/org-ref) - orgmode's support for RefTeX (https://www.gnu.org/software/auctex/reftex.html) which is mentioned in the wiki (http://wiki.contextgarden.net/Reftex) or is is better to excusively work within the scope of ConTeXt? I've also noticed that Bibliogrpahies manual does mention JabRef and Zotero for managing databases, so I'd appreciate if ConTeXt users can share their experience in regard? Sincerely, Gour -- An intelligent person does not take part in the sources of misery, which are due to contact with the material senses. O son of Kuntī, such pleasures have a beginning and an end, and so the wise man does not delight in them.

Hi, Here is a sample code of framed text with titles using FunnyFrame. I tried to use it to display theorems “Theorem #.#” inside the FrameTitle, and the text in FunnyFrame. So, I defined “\defineenumeration[Thm]”. But I couldn’t make it. Is it possible to do that? If so, please let me know how to do the following two things. 1. to put “Theorem #.#” inside the FrameTitle?(#.# means that chapter number.theorem number) 2. to suppress the automatically display of “Thm #” inside the text?
