Attributes
by Stéphane Goujet 24 Apr '14

24 Apr '14

Hello, I would like to know what is the recommended way to use attributes in Context. I manage to use use them with numbers, i.e. : in Context : \attribute123=1 in Lua : has_attribute(my_node, 123) But I would like to make that cleaner and use named attributes. What is the Context way to declare and set attributes? Is it something like this? \defineattribute[myattr] \dosetattribute{myattr}{1} And how do I then access them from Lua? Should it look like has_attribute(mynode, attributes.myattr) or has_attribute(mynode, attributes.xxxxx("myattr")) or something else? Goodbye, Stéphane.

\setupmathradical[sqrt] crunches denominator in an \over fraction
by Sanjoy Mahajan 24 Apr '14

24 Apr '14

I have been trying out the newish \setupmathradical[sqrt][alternative=mp], which has been very nice because of the fine control over the radical sign. I've noticed that it crunches the denominator in \sqrt{a\over b} For example: \starttext \placeformula\startformula \sqrt{k\over m}\quad \sqrt{\displaystyle{k\over m}} \stopformula \setupmathradical[sqrt][alternative=mp] \placeformula\startformula \sqrt{k\over m}\quad \sqrt{\displaystyle{k\over m}} \stopformula \stoptext In the first line, the fractions come out fine. In the second line, the first k\over m has a small, inline-math m in the denominator but a display-math k in the numerator. The second sqrt is fine. Is the problem that my plain-TeX habits, from decades using \over, should be over, and that \frac is the recommended way? (This is with the 2014.03.27 beta.) -Sanjoy

Attach (embed) a file info a .pdf
by Procházka Lukáš Ing. - Pontex s. r. o. 24 Apr '14

24 Apr '14

Hello, I'm not able to recall the way how to attach a file into a .pdf being generated. I need the attached files to be "openable" or "savable" from the .pdf - see the image. How to achieve this with ConTeXt? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Orphans/Widows in the Index
by Jan Tosovsky 23 Apr '14

23 Apr '14

Dear All, in my auto-generated two column index (registry) there are several cases of widows - it is the last item of the given letter which overflows to next column/page: --------------- (start page) ------- Usti 29 (!!! - I would expect to place here also one or better two previous entries) V Vamberk 18 ... ... There are also few cases of orphans, but this is not so strange: ... ... Josef 29 K (!!! - both these lines could be moved to the next column/page) Karel 69 ---------------- (end page) --------- In my setup I have defined: \startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{2}{10000} % change to {3}{10000} doesn't help \setpenalties\clubpenalties {2}{10000} \stopsetups \setuplayout[grid=yes, setups=mypenalties] It is hard to provide MWE. Moreover, the content is for private use only. Is there any remedy for this? Thanks, Jan

Broken bibliographies in 2014-03-07 beta
by Rik Kabel 23 Apr '14

23 Apr '14

Bibliographies are no longer generated. MWE is the example code at http://wiki.contextgarden.net/Bibliography_mkiv, which no longer generates an output file and shows the following in the blg file: I found no \citation commands---while reading file cite.aux I found no \bibdata command---while reading file cite.aux I found no \bibstyle command---while reading file cite.aux You've used 0 entries,... With the stable version, the same section reads: Database file #1: sample.bib You've used 4 entries, -- Rik

Linenumbering
by MANUEL GONZALEZ SUAREZ 23 Apr '14

23 Apr '14

Hello everyone. I give a small example: \setuppagenumbering [alternative=doublesided] \setuplinenumbering[location=outer, step=5, method=page, style=\tfxx, align=left, distance=1em, width=0.4em] \starttext \section{First section} \startlinenumbering text text text \stoplinenumbering \section{Second section} \startlinenumbering text text text \stoplinenumbering \stoptext The problem is that although appears the option [method = page], numbering begins at the beginning of each section. I would like the title of the section does not appear as numbered line but continue after the title the above numbering, e.e.: \startlinenumbering \section{First section} no numbered line Numbered line (1) Numbered line (2) \section{Second section} no numbered line Numbered line (3) Numbered line (4) ... \stoplinenumbering Thanks very much?

A couple of setupcaptions questions revisited
by Rik Kabel 22 Apr '14

22 Apr '14

On 2011-08-05, Wolfgang wrote with regard to section numbering not appearing in float captions when numbering is off for the section but called for by the chapter (http://www.mail-archive.com/ntg-context%40ntg.nl/msg57811.html): For the moment replace "number=no" with "incrementnumber=no". and later that day (http://www.mail-archive.com/ntg-context%40ntg.nl/msg57814.html): There is a bug but it takes time to find it, unless it is found and fixed use incrementnumber. BTW: A *minimal* example your problem is **this**: \setupformulas[way=bysection,prefixsegments=chapter] %\setuphead[subsection][number=no] \setuphead[subsection][incrementnumber=no] \starttext \chapter{Chapter 1} \chapter{Chapter 2} \section{Section} \subsection{Subsection} \placeformula \startformula a^2+b^2=c^2 \stopformula \stoptext This bug appears to still be with us. Has a solution since been proffered? If not, is a resolution in sight? -- Rik Kabel

Re: [NTG-context] passing arguments to \processMPbuffer
by Jeong Dal 22 Apr '14

22 Apr '14

Dear Wolfgang, Thank you for your solution. Sometimes I need to use \processMPbuffer for the animated graphics. BTW, what is the differences between ‘MPrawvar’ and ‘MPvar’. MPvar didn’t work in your example. Best regards, Dalyoung

Ruby warnings when running texexec
by Jonathan Budd 22 Apr '14

22 Apr '14

Hi all Whenever I run texexec I encounter a series of warnings from Ruby. For example, running texexec —version returns the following: texexec --version /usr/local/texlive/2013/texmf-dist/scripts/context/ruby/texexec.rb:688: warning: class variable access from toplevel /usr/local/texlive/2013/texmf-dist/scripts/context/ruby/texexec.rb:695: warning: class variable access from toplevel /usr/local/texlive/2013/texmf-dist/scripts/context/ruby/texexec.rb:702: warning: class variable access from toplevel /usr/local/texlive/2013/texmf-dist/scripts/context/ruby/texexec.rb:703: warning: class variable access from toplevel TeXExec | version 6.2.1 - 1997-2009 - PRAGMA ADE/POD Is there any way to remove this warning? The warning seems to interfere with AucTeX 11.87 and prevents it from registering a successful compilation of the document. I am running MacTeX 2013 and ruby 2.0.0p451 (2014-02-24 revision 45167) [universal.x86_64-darwin13] on a 15” MacBook Pro with OS X 10.9.2. Kind regards Jonathan
