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

comment inside mathml

Sorry if this question reaches you twice, but the first time I used an email address not registered with this newsgroup. Shouldn't mathml ignore the xml comment in the second example below? Hans van der Meer

annotation?
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 following mathml code typesets "x+1" twice. How can I select between either the mathml code or the annotation form? Thus avoiding having them typeset both. Hans van der Meer \startbuffer[example-1] <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE math PUBLIC "-//W3C//DTD MathML 2.0//EN" "http://www.w3.org/Math/DTD/mathml2/mathml2.dtd"> <math mode="display" xmlns="http://www.w3.org/1998/Math/MathML"> <mrow><mi> x </mi> <mo> + </mo> <mn> 1 </mn> </mrow> <annotation encoding="TeX"> x + 1 </annotation> </math>

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

18 May '14

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

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.

Figure numbering with parts
by Pol Stra 17 May '14

17 May '14

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.
