Interactive U3D in .pdf via ConTeXt?
by Lukáš Procházka 20 May '14

20 May '14

Hello, is there way to include U3D (or X3D after conversion) into a .pdf via ConTeXt? - An example of such an embed object and its capabilities at http://www.behaviometrix.com/public_html/brain.pdf LaTeX offers this via movie15 package; is it possible to produce such document with ConTeXt?

Using the margin for two purposes
by Matthias Weber 20 May '14

20 May '14

Dear All, I would like to use the margin for two different purposes: For brief notes, using \inmargin, and to mark entire paragraphs sections of the text with vertical lines. So, I’d like to be able to something like this \starttext \startsquigglyline \inmargin{read \\ this \\ first} \input{knuth} \stopsquigglyline \startthinline \inmargin{read \\ this \\ next} \input{tufte} \stopthinline \stoptext I know I could use frames to accomplish the vertical features within in the text area, but I’d prefer to use the margin so that framing paragraphs doesn’t indent the paragraphs compared to the unframed portions. But I also want to have the \inmargin notes to be lined up properly. So it looks like I would need to divide the margin into two horizontally separate regions. On left pages, the left region would be used for the \inmargin notes, and the (very thin) right region would be used for the vertical features (squigglyline and thinline). For right pages the other way around. Of course I’d also like the vertical features to extend across pages, if needed. Like so: Left Page Right Page read ( Knuth Tufte | read this ) Knuth Tufte | this first ( Knuth Tufte | next ) Knuth Tufte | ( Knuth Tufte | Is there a mechanism in place for that? Thanks for any hints! Matthias

mathml <mtext> behaviour
by H. van der Meer 18 May '14

18 May '14

Sorry if this question reaches you twice, but the first time I used an email address not registered with this newsgroup. The short example below typeset with \usemodule[mathml] \starttext \typebuffer \blank \processxmlbuffer \stoptext and "ConTeXt ver: 2014.04.04 00:08 MKIV beta" shows that the <mtext> element does not honour the tags within. This severely restricts the presentation. Can this be remedied? Hans van der Meer Hans van der Meer

extending \setuparranging[2*4*2]
by Pablo Rodriguez 18 May '14

18 May '14

Willi, following the advice from Hans, I’m asking whether you would be interested in extending \setuparranging. As already explained in previous messages, I think it would be useful to have \setuparranging[2*4*2] for any given number of pages. Having 16 pages to impose isn’t always an option. I read page-imp.mkiv again and I have no idea about how to achieve this. (I found three typos that I attach to this message.) Could you extend \setuparranging[2*4*2] to accept any given number of pages? Many thanks in advance, Pablo -- http://www.ousia.tk

scientific notation in PDF file
by Michail Vidiassov 18 May '14

18 May '14

Dear Developers and All, when I create a PDF dictionary with a small number local mydict = lpdf.dictionary { TT = 0.000000000000000001 } lpdf.flushobject(mydict) I get in PDF << /TT 1e-18 >> that confuses the Adobe Reader (if dictionary is used). As far as I can investigate, lpdf.flushobject(mydict) calls pdf.immediateobj(tostring(mydict)) and tostring does the actual damage by introducing scientific notation. What is the correct way to deal with the problem? Converting the dictionary to string with my own code looks like a possible workaround, not a solution. Michail PS. Minimal example (it produces unused dictionary, so viewer does not complain) \nopdfcompression \starttext \startluacode local mydict = lpdf.dictionary { TT = 0.000000000000000001 } lpdf.flushobject(mydict) -- or, to the same result -- pdf.immediateobj(tostring(mydict)) logs.reporter("","")("mydict %s",tostring(mydict)) \stopluacode Test. \stoptext Context is current version: 2014.05.13 00:04

numerator is too high in \frac{3}{4}, in palatino
by Sanjoy Mahajan 18 May '14

18 May '14

I've noticed the following issue with how high the numerator is placed, but only when using Palatino: \setupbodyfont[palatino] \starttext \startformula {3\over4}\quad {1\over2} \stopformula \stoptext The 3 and the 1 sit quite high above the division line, esp. in comparison with the gap below the line (above the 4 and the 2). The place okay without the \setupbodyfont[palatino], so maybe it is something incorrect in the font parameters? The fonts are (from 'pdffonts'): EUEJAR+TeXGyrePagella-Regular CID Type 0C Identity-H yes yes yes 18 0 UPBTGS+TeXGyrePagellaMath-Regular CID Type 0C Identity-H yes yes yes 19 0 And it is compiled with 2014.03.27 20:04 MKIV. Is there a way to adjust the spacing, or an alternative workaround? -Sanjoy

LuaTeX-plain - Get well-know function names like sin & cos to display in roman
by Aíre Funvake 17 May '14

17 May '14

Hi there, Am used to seeing the names of well known functions in upright math font, instead of italics. With LaTeX, it seems, this is default, plus one can use macros like `\mathrm` or `\textrm` for other text. An `\hbox{}` too, in plain TeX, but not around `\sin`, for example. With ConTeXt's LuaTeX-Plain format (may ConTeXt itself as well), these functions are in italics. Is it possible to control this via the redefinition of the math fonts? Following does not work for me: \font\lmromr = {LucidaBrightMathOT:mode=base} at 14pt \font\lmromi = {LucidaBrightMathOT:mode=base} at 14pt \font\lmromsr = {LucidaBrightMathOT:mode=base;script=math;ssty=0} at 12pt \font\lmromsi = {LucidaBrightMathOT:mode=base;script=math;ssty=0} at 12pt \font\lmromssr = {LucidaBrightMathOT:mode=base;script=math;ssty=1} at 10pt \font\lmromssi = {LucidaBrightMathOT:mode=base;script=math;ssty=1} at 10pt \textfont0 = \lmromr %--sin, cos, numbers \scriptfont0 = \lmromsr % \scriptscriptfont0 = \lmromssr % \textfont1 = \lmromi %--variables \scriptfont1 = \lmromsi % \scriptscriptfont1 = \lmromssi % \textfont2 = \lmromr %--symbols \scriptfont2 = \lmromsr % \scriptscriptfont2 = \lmromssr % \textfont3 = \lmromr %--extras \scriptfont3 = \lmromsr % \scriptscriptfont3 = \lmromssr % Same for CambriaMath or LatinModernRomanMath. For `\<font>0`, tried a non-math font, but it did not work. How to set `\<font>0` to use roman? and `\<font>1` to use italics? Thanks in advance, Aire. PS.

Hello, I want to number my figures like this: partnumber.sectionnumber.figurenumber I didn't find documentation on \setupnumber. I tried: \setupnumber[figure][way=bypart, numberpart=yes] \setupnumber[figure][way=bypart, numberpart=yes, prefixsegments=part] But when changing part, the numbering starts again at 1. Thanks

ConTeXt Garden Examples Maintenance
by Thangalin 17 May '14

17 May '14

Hi, The ConText Garden wiki has numerous short example sprinkled throughout its pages. I presume that they are hard-coded in the page. if the example breaks (due to a ConTeXt bug or backwards-incompatible enhancement), I imagine there is no notification. What do you think about creating a repository of examples that are included by embedding a website address instead of direct text? For example: 1. User visits wiki. 2. User edits a page (e.g., Command/setuphead). 3. User names and uploads a .tex document. 4. System generates unique hyperlink for .tex document. 5. System generates and includes embed code into wiki page, such as: <context href="http://wiki.contextgarden.net/context/examples/file.tex" /> <context href="/context/examples/file.tex" /> Also, source="yes" and mode="mkiv" should be the default. Then, if the person editing the page wants to include the output, the full example might resemble: <context href="/context/examples/file.tex"> This produces: <context output="yes" href="/context/examples/file.tex"> Having the complete examples separated allows the snippets to be tested automatically. Broken .tex examples (unless explicitly flagged) would result in notifications being sent to the page maintainer(s). A broken example could be flagged as: <context notify="no" href="/context/examples/file.tex"> Another advantage is that all the examples could be downloaded and possibly referenced in other media. Kindest regards.

LuaTeX-plain File Database Problem
by Aíre Funvake 17 May '14

17 May '14

Hi all, Never felt so incompetent in my life -- just cannot get LuaTeX to find fonts or `*.tex` files for use with `\input <filename>`, or `font\xxx = <font-or-filename>`. Even though, these commands were executed (all I could find): mktexlsr mtxrun --script base --generate luatools --generate context --generate mtxrun --script fonts --update --force mtxrun --script fonts --udpate --simple Tried putting files in (in the roots and subdirectories): ~/texmf ~/ctx/tex/texmf-project ~/ctx/tex/texmf-local ~/ctx/tex/texmf-fonts Checked if the file could be found: luatools --find-file xxxx.tex <--- finds it luatools --find-file xxx.otf <--- finds it mtxrun --locate xxxx.tex <--- finds it mtxrun --locate xxx.otf <--- finds it kpsewhich/where <--- finds only if in `~/texmf` In .tex file (even when files are in `~/texmf` dir): \input xxxx or xxxx.tex <--- no luck \font\myfont = name:xxxx <--- no luck \font\myfont = file:xxxx.otf <--- no luck Sorry, but reading and searching for hours did not bring any solu- tion. Not sure if there is a configuration file like `texmf.cnf` or the `context.cnf` that must be modified, or and environment var- iable like `TEXMFHOME` (default seems to be `~/texmf`, and that's OK, if only it would only work). Sorry to spam this list with questions which may seem very fundamental to you. Hope to be able to reciprocate sometime. What am I missing? Thank you kindly, Aíre.

basic question on imposition
by Pablo Rodriguez 16 May '14

16 May '14

Dear list, I’m trying to build a booklet from an existing PDF document, my code is the following (copied from the wiki long time ago): \setuppapersize [A5][A4,landscape] \setuparranging [2UP,doublesided] \setuplayout [backspace=0pt, topspace=0pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt, grid=no, marking=off] \starttext \insertpages[document.pdf][width=0pt] \stoptext It works perfectly, but I would like to achieve the same effect, only imposing 4 pages on each side of the paper (8 pages per sheet). Replacing the first two lines with: \setuppapersize [A6][A4] \setuparranging [2*4] rearranges all pages, but not the way I want. With the previous option, I have to cut the paper in four. I would like to avoid this. I would like to cut the A4 in two landscape A5 to be folded (not cut) in two A6 pages. Which is the way to get this imposition? Many thanks for your help, Pablo -- http://www.ousia.tk

Font expansion only, applied to a limited character subset Is that true? It is applied to any character that you want, of course given that you associate expansion factors, but that happens for quite some characters in context. Concerning homogenization, context has support for dynamically aplying feature (alternates) to improve the look and feel but of course not many fonts have multiple variants for glyphs grouped in stylistic alternates so this mechanism is hardly used (only for some arabic).
