Re: [NTG-context] Simple command with variable number of arguments

Dear Luigi and listers, Last year, I need to write a text for a linear algebra class. Since there are many \startmatrix … \stopmatrix and matrix calculations, I wrote a lua code which did matrix calculations and writing with a lot of help from this list. Using the code, I can write class materials easily. It is good enough for my purpose. I am not good in Lua coding, so there may be many things to be checked for efficiency and for stability. However, I attached the code because there may be someone who need it. It is also good thing to return what I get from the list back. I hope that you enhance the code for better performance since you are an expert in Lua. I always thank to this list and to developers of ConTeXt.

Experience with DITA XML or XSL/FO
by Mica Semrick 23 May '14

23 May '14

Hi list, I've been contemplating making a ConTeXt output or parser for DITA XML and was wondering if anyone has worked with DITA and ConTeXt before? If you have and could offer any advice and/code, that would be most helpful! Best, Mica

Bold small caps
by Mojca Miklavec 23 May '14

23 May '14

Hi, I always forget how to use bold or italic small caps (I keep mixing addff/setff and smcp/+smcp/smallcaps etc.). In ideal world it could be nice if simply {\sc Normal and \bf Bold Small Caps} or {\bf\sc Bold Small Caps} would work out-of-the-box. The first hit on the wiki was http://wiki.contextgarden.net/Bold_small_caps which contained just the MKII example. I added a MKIV example {\setff{smallcaps} Normal and \bf bold Small Caps.} but the problem is that this example only works with <put any font name here> except for the default Latin Modern setup. Would it make sense to fix this for the default LM setup as well? Mojca

\setuplist ignores width=<dim> in combination with headnumber=no
by Mojca Miklavec 23 May '14

23 May '14

Hi, I would like to remove header numbers for subsections, but keep subsections properly aligned in the table of contents. However, the width= parameter seems to be completely ignored in that case. Here's a nearly-minimal example: \setuplist[section][width=10mm,style=bold] \setuplist[subsection][width=15mm,headnumber=no] \setuplist[subsubsection][width=20mm,style=slanted,pagestyle=normal] \starttext \completecontent \page[yes] \section{First section} \subsection{First subsection} \subsubsection{First subsubsection} \subsubsubsection{First subsubsubsection} \section{Second section} \subsection{Second subsection} \subsubsection{Second subsubsection} \subsubsubsection{Second subsubsubsection} \stoptext The example has been adapted from http://wiki.contextgarden.net/Table_of_Contents. The image on the wiki seems ok, but I get a different result if I try to run the same example with the latest version of ConTeXt (mkiv). Somewhat related: say that I wanted to setup \setuplist[<name>][width=10mm] for all the sections and sub(subsub)sections. The documentation seems to suggest that \placecontent[aligntitle=yes/no,width=10mm] should do that (it's not clear to me whether that's yes or no that should do it), but it doesn't seem to have any effect at all.

Simple command with variable number of arguments
by Matthias Weber 23 May '14

23 May '14

Dear All, I would like to define a command that expands \vector{2,4} % or vector[2,4] if that’s easier to \startpmatrix \NC 2 \NR \NC 4 \NR \stoppmatrix and more generally \vector{2,4,1,7} to \startpmatrix \NC 2 \NR \NC 4 \NR \NC 1 \NR \NC 7 \NR \stoppmatrix Any hints how to achieve this? Thanks, Matthias

Italic small capitals with Latin Modern font
by Maggyero 23 May '14

23 May '14

How can I use Latin Modern italic small capitals? I have seen on a previous thread that small caps are separated in an other file for Latin Modern font and that one should load it to use them in italic, but there was no example given to achieve that. Minimal example: \starttext \it \sc \input knuth \stoptext

Re: [NTG-context] \startbackground with footnote
by Xan 23 May '14

23 May '14

It has some bug against footnotes. I attach an example. Sorry, it's not a minimal example, but I can't reproduce it with minimal. I think the important think is the page break because the table two does not fit in the page. I get one empty page here. I attach the .tex and the pdf. Thanks in advance, Xan.

You don't have to install full TeX Live. Just install the basic scheme (plain TeX) + "latexrecommended" collection. On one of my machines that fits into 110 MB, but you could probably be even more picky and install even less packages (or remove them later after installation). Just start with tlpretest 2014, else your installation will become obsolete before you know. Mojca

Setting the style and conversion of the reference numbers for the \in command
by Maggyero 23 May '14

23 May '14

Thank you Wolfgang, your hack is perfect. Hans, what do you think about adding a style and color key in \setupreferencestructureprefix to avoid having to use this defineprocessor hack? And by the way, the name \setupreferencestructureprefix does not sound really natural to me because we are talking about a reference NUMBER and there is not always a prefix. What about changing it to something like \setupreference or \setupreferencenumber (like \setuppagenumber)?

Setting the style and conversion of the reference numbers for the \in command
by Maggyero 22 May '14

22 May '14

I have found how to get the conversion of numbers in references (the 'prefixconversion' key in '\setupreferencestructureprefix' command), but I still do not know how to change their style. I have tried the 'style' key and 'prefixstyle' key but without success. After checking in ConTeXt source, I have realised that there is no such 'style' key for the '\setupreferencestructureprefix' command. Is there another command to change the style? If not, it would be great if Hans could add that feature. Minimal example: \setupreferencestructureprefix[section][default][% prefixconversion=Romannumerals, prefixstyle=\bf] \starttext \input knuth (Cf. \in{section}[mysection].) \section[mysection]{My section} \stoptext

pdf X/1-a:2001 format for print output.
by john Culleton 22 May '14

22 May '14

The above format is required for pdf files containing color for many American printers. I am looking for the minimal case. In the wiki there is an example: \setupbackend [format=PDF/X-1a:2001, intent=SWOP2006_Coated3v2.icc] Is this sufficient? Or must I also use this code: \setupinteraction [title=TITLE, subtitle=SUBTITLE, author=AUTHOR, keyword={{KEYWORD1, KEYWORD2}, KEYWORD3}] I don't see the relationship of this last example to non-interactive pdf X/1-a:2001 output for print. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

ConTeXt mkiv and rsfs fonts
by Otared Kavian 22 May '14

22 May '14

Hi all, It seems that the rsfs fonts (Ralph Smith’s Formal Script fonts) do not work: the procedure explained at the page http://wiki.contextgarden.net/rsfs works fine with mkii, but not in mkiv. Is it possible to use the capabilities of simplefonts, which are now included in mkiv, to use this script font in place of the usual \cal when using LM fonts (or even Palatino)? Thanks in advance for any insight. Best regards: OK

\setnumber
by Werner Hintze 22 May '14

22 May '14

I don’t unterstand \startfrontmatter, \starbodymatter etc. I thought, the frontmatter has roman numerals, the bodymatter normal and so on. This is not automatically so. Now founf how to make this, bus the problem is: I can’t reset the page number. I believed, it shoul work like this: \startfrontmatter \setupuserpagenumber[numberconversion=Romannumerals] % some stuff \stopfrontmatter \startbodymatter \setupuserpagenumber[numberconversion=numbers] \setnumber[page]{1} %some stuff \stopbodymatter This doesn’t work, may be because \setnumber is not a command in ConTeXt? Where is my error?

MathML in ConTeXt conforming to MathML3?
by Meer, H. van der 21 May '14

21 May '14

Does the MathML in ConText conforms to the MathML3 specification? (see http://www.w3.org/TR/MathML3/chapter5.html) I find that with \usemodule[mathml] (1) <semantics><annotation encoding="application/x-tex">TeX-code</annotation></semantics> does not typesets, but (2) <semantics><annotation encoding="tex">TeX-code</annotation></semantics> does. As I understand from the specification, (1) should have been correct, but does not processes the TeX and the attribute "application/x-tex" seems not to be recognized. Does ConTeXt-MathML deviates in this respect from the current standard? Or do I miss some important fact? Hans van der Meer

Metapost and Metafun

Hi, As PSTricks (which I prefer) is not yet well integrated, I decided to learn Metapost starting with a simple code. \starttext \startMPcode numeric xmin, xmax, ymin, ymax; xmin := -2.5; xmax := 2.5; ymax :=2.5 ;ymin:=-2.5; u := 2cm; vardef f(expr x) = -x*x+1 enddef; xinc := 0.001; path pts_f; pts_f := (xmin,f(xmin))*u for x=xmin+xinc step xinc until xmax+xinc: .. (x,f(x))*u endfor; path axe_x,axe_y; path screen; screen=(xmin,ymin)*u--(xmax,ymin)*u--(xmax,ymax)*u--(xmin,ymax)*u--cycle; axe_x = (xmin,0)*u -- (xmax,0)*u; axe_y = (0,ymin)*u -- (0,ymax)*u; drawarrow axe_x; drawarrow axe_y; draw pts_f withpen pencircle scaled 1; clip currentpicture to screen; \stopMPcode \stoptext Are there any routines with Metafun to improve this code? thank you, Fabrice

stretching/expanding Greek characters
by Alan Bowen 21 May '14

21 May '14

I am trying to typeset some compendia found in a medieval Greek manuscript and would like to stretch or expand several characters in my font. So far, I have mostly found information about stretching the inter-word spacing (tracking). There is, however, discussion in a few places of what I want in Arabic but I am at a loss to see how I might adapt this to Greek. If this is even possible, I would be grateful for any suggestions or pointers. My Greek font, defined as a fallback, is IFAO Grec Unicode (regular only). Alan

Blindtext
by Werner Hintze 21 May '14

21 May '14

And just another strange question: Is there any command like \blindtext (or \blinddocument) in LaTeX? I just try to figure out how Kontext works, and so it would ne fine to have some texte every time available. (I can put some text from everywhere, but the blindtext package is much more comfortable.) Thank you!

Fwd: Oldstyle numbers
by Werner Hintze 21 May '14

21 May '14

I’m new to ConText and so my question may be a stupid one. But I hope somebody can help me: How can I activate »old style numbers« (Medievalziffern). I thought, it should work like this: \setupbodyfont[palatino, 10pt] \definefontfeature [default] [default] [onum=yes] But this doesn’t work. What do I have to do? Many thanks for your help!

SimpleFonts

I just installed the "standalone" context and tried to typeset a document which uses "simplefonts" but the resolver indicates that simplefonts is not found. This isn't surprising, but I need to learn how to install simplefonts to use with the standalone. Use adding " --modules all" as an option to first-setup.sh do this? Any advice is appreciated.

larger dot for \dot ?
by Sanjoy Mahajan 20 May '14

20 May '14

My students complain that the dot in, for example, $\dot M$ is too small and that they easily miss it. So I have been trying to make a bigger one, but haven't found a solution that plays nicely with the surrounding math. For example, \def\mydot{\overset{\externalfigure[dot.pdf]}} %bigger than usual one \def\Vdot{\mydot V} \starttext $\rho\Vdot\omega$ % loose spacing $\rho V\omega$ % tighter spacing \stoptext where dot.pdf is a circle of radius 0.8bp (attached). But the \Vdot gets wrapped in an hbox (inside \overset), so the surrounding space is too large. I also tried a metafun approach \startuniqueMPgraphic{math:mydot} fill unitcircle scaled 2 shifted (OverlayWidth/2-1,OverlayHeight+OverlayOffset); path q; q:= unitsquare xscaled OverlayWidth yscaled (OverlayHeight+OverlayOffset+1); setbounds currentpicture to q; \stopuniqueMPgraphic \definemathornament [mathmydot] [mp=math:mydot] \starttext $\rho\mathmydot{V}\omega$ $\rho V\omega$ $\rho\mathmydot{V}_0^2\omega$ $\rho\dot{V}_0^2\omega$ \stoptext The $\rho\mathmydot{V}\omega$ looks good. But the subscripted _0 is not tucked under the V, because the bounds of the character are now a rectangle that doesn't know about its shape. I think for a similar reason the superscripted 2 is quite high. Is there more math-friendly (and elegant) way to get a fatter dot? -Sanjoy

Entering text into layers
by Keith McKay 20 May '14

20 May '14

Colleagues I have been designing a simple document which comprises of 4 areas (3 for text, 1 for images) on an A4 page. I thought that the best way to do this would be using Layers and so far I come up with the code below after scanning the wiki. As you can see it is not very sophisticated, but I'm not a regular user of Context. The question I have is what would be the best way to add text to the various layers? Some would have quite a lot of text and I was wondering if would be better to define the text for the different layers in some way rather than enter into the braces of \setlayerframed. The code would look messy this way. Finally, can layers be positioned within layers or would it be better to use overlays? I'm thinking about adding three columns to the Footer layer. Thanks for your help Best Wishes Keith McKay \setuplayout [backspace=0cm, cutspace=0cm, width=fit, topspace=0cm, bottomspace=0cm, header=0cm, footer=0cm, height=fit] \setupexternalfigures[location={local,global}] \definelayer[Logo] \definelayer[Picture] \definelayer[Text] \definelayer[Footer] \starttext \strut \setlayerframed[Logo][x=1cm,y=1cm] [width=19cm,height=3cm,background=color,backgroundcolor=lightgrey] {Some text in here} \setlayerframed[Picture][x=1cm,y=5cm] [width=6cm,height=19.7cm,background=color,backgroundcolor=lightgrey]{\externalfigure[picture.jpg][background={foreground,figure},maxwidth=6cm]} \setlayerframed[Text][x=8cm,y=5cm] [width=12cm,height=19.7cm,background=color,backgroundcolor=lightgrey]{Text goes here} \setlayerframed[Footer][x=1cm,y=25.7cm] [width=19cm,height=3cm,background=color,backgroundcolor=lightgrey] {Footer goes here} \setupbackgrounds[text][background={Logo,Picture,Text,Footer}] \stoptext
