header variations how?
by Meer, H. van der 16 Apr '13

16 Apr '13

I tried to put the sectionnumbers in the margin, but it didn't work. The I looked at the example in the ConTeXt Reference Manual and this didn't work either. Why? See the minimal example below where the manual is contrasted with the actual output. Hans van der Meer \setuppapersize[A5][A5] \starttext \startchapter[title=Test] >From ConTeXt Reference Manual 18 october 2012 page 210\crlf \externalfigure[headers.jpg][width=0.8\textwidth] \startsection[title=enclosing section] \setupheads[alternative=normal] \subsection{Title alternative equals normal} \setupheads[alternative=inmargin] \subsection{Title alternative equals inmargin} \setupheads[alternative=middle] \subsubject{Title alternative equals middle} \stopsection ConTeXt ver: 2013.03.20 10:34 MKIV fmt: 2013.3.20 \stopchapter \stoptext

Re: [NTG-context] Overlapping \starthanging \stophanging with side captions
by Peter Sienkowski 16 Apr '13

16 Apr '13

Wolfgang, thank you very much for your answer about placing text. Using: \startplacefigure[location=force,title={First dummy caption}] \inmargin{First margin dummy} \externalfigure[dummy][width=\textwidth] \stopplacefigure The text in the \inmargin section appears at the bottom of the figure. This works for about one line of text. For some of the figures I'm trying to put 3-4 lines in a wide margin and would like the text to appear at the top or the middle of the figure. I asked a question over at Stackexchange on this: http://tex.stackexchange.com/questions/107856/placing-text-in-the-margin-ne… Using \starthanging \stophanging put the text in the correct place but then the figures ran into each other. regards Pete

Zoom to a box when clicking
by Aditya Mahajan 16 Apr '13

16 Apr '13

For a presentation, I want to display a series of images as a combination and be able to click on an image to zoom into that image and click again to zoom out. Is it possible to do that? In general, can I create a hyperlink such that clicking on it zooms in on a particular rectangular region on a page? Thanks, Aditya

vskip in lines

With \vskip-0.9cm one can relocate 0.9cm. If one uses grid-setting, it would be easier to give the dimension in lines, like \vskip-2*line – but this gives an error, how to do that correctly? Huseyin

tikz-cd - commutative diagrams
by Idris Samawi Hamid ادريس سماوي حامد 15 Apr '13

15 Apr '13

Dear gang, The tikz module works, as per the attached attached test file. I need some commutative diagrams and found something relatively recent and interesting: http://www.ctan.org/pkg/tikz-cd But \input'ing the file tikz-cd.tex after the tikz module does not work; I get an undefined control sequence for a normal tikz command. I commented the LaTeX commands % \ProvidesPackage{tikz-cd}[2012/12/30 v0.3c Commutative diagrams with tikz.] % \RequirePackage{tikz}[2010/10/13] % pgf version 2.10 required and the rest is just pgf syntax. What else do I need to do to get this working properly? Do I need to place tikz-cd in the pgf tree? If so, where? In the attached I have not used any code that depends on tikz-cd; comment \usemodule[tikz-cd] and the file runs fine. Thanks for any advice and Best wishes Idris -- Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523

Vertical location of combinations
by Aditya Mahajan 15 Apr '13

15 Apr '13

How do I control the vertical location of combinations? I want output similar to ABC \framed[frame=no, location=top]}\startcombination[2] {\externalfigure[dummay][width=2cm]}{One} {\externalfigure[dummay][width=2cm]}{Two} \stopcombination} DEF without having to explictly add a \frame. Looking at pack-com, I tried \useMPlibrary[dum] \setupcombination[location=top] \starttext ABC \startcombination[2] {\externalfigure[dummay][width=2cm]}{One} {\externalfigure[dummay][width=2cm]}{Two} \stopcombination DEF ABC \framed[frame=no, location=top]}\startcombination[2] {\externalfigure[dummay][width=2cm]}{One} {\externalfigure[dummay][width=2cm]}{Two} \stopcombination} DEF \stoptext but the combination is still aligned to the baseline of the caption. Thanks, Aditya

> You can try to add > > \definelayout[<pagenumber>][grid=no] > > to your document where you replace <pagenumber> with the number of the page where your TOC starts. > > Wolfgang Thanks for this idea, but it does not work. The grid=no is simply ignored for the toc-page (as many grid=no options are ignored in many environments and commands, seems to be field open for improvements). Is there another idear for a workaround? At the moment I have only one option: resigning these different font sizes in the toc, which are defined manually absolutely (possible, but awkward) Is there maybe another "trick" to deactivate gridsetting, analogical to placeongrid, or tricks with tables, or so? I am experimenting here, too, of course :) Huseyin

Figures and Lua (continuing "Number of pages by Lua of a figure to be inserted?" somehow)
by Procházka Lukáš Ing. - Pontex s. r. o. 15 Apr '13

15 Apr '13

Hello, I tried to make a "more minimal" example. Still we have: files: ./t3.mkiv ./T/Kn.pdf and code: ---- \startluacode test = function(fn) local fig = figures.push{name = fn} if figures.identify().status.status ~= 0 then figures.check() end figures.pop() return fn .. ": " .. (fig.used.pages or "?") .. "\\par" end \stopluacode \starttext AAA \startluacode context(test("T/Kn.pdf")) -- Found - OK context(test("Kn.pdf")) -- Not found - OK \stopluacode \setupexternalfigures[directory=T] \startluacode context(test("Kn.pdf")) -- Not found (or unknown number of pages) - UNEXPECTED - why? ("3rd call") \stopluacode \externalfigure[Kn.pdf][scale=625] % Found - OK \stoptext ---- The 3rd call of 'test()' seems to not locate 'Kn.pdf' although the path was altered by preceding \setupexternalfigures. How to modify the 'test()' to work properly even in the 3rd case? NB: Sorry for repeating the topic "in another coat" - it may not be so interesting for listeners of this mailing list. But the goal is to add figures and PDF files into the document automatically. One of the tasks is to detect number of pages of the figure. The code above is a core cut out; it should work (or: if this part wouldn't work, neither would the rest) even in the 3rd case. Any help to make the piece of code work would be appreciated.

[***SPAM***] Title of figure not below the figure, but on the right side
by "H. Özoguz" 15 Apr '13

15 Apr '13

I usually use: \startplacefigure [title=Some very explanative title.] \externalfigure[tollesbild][width=2cm] \stopplacefigure And this sets the title under the figure, perfect for me in general. But now I have a figure, where the (pretty long) title-text should be on the right side, how to get this? Huseyin

Deactivating gridsetting for TOC
by "H. Özoguz" 15 Apr '13

15 Apr '13

Hi there, thanks for the many helps today, again! Because I use different font sizes for the titles in the TOC (depending on the title-level), I have problems with grid-setting. It makes sometimes blank lines between two titles in the toc. I understand that behaviour, it is because of the different sizes. Instead of involved testings with different sizes and vertical spaces, can I simply switch off the grid-setting for the toc? That would be the easiest. I tried \placeongrid{\completecontent}, and that works, no more blank lines. But now the complete toc is set on one page only, but the toc is much to big for only one page, so it is set beyong the page buttom, and disappears in the pdf-nirvana :D Is there a feature/option "grid" for toc in \completecontent or anything like that? Thanks. Huseyin

Joinedup itemization with margin
by "H. Özoguz" 15 Apr '13

15 Apr '13

Hi there, I want a joined itemization (I just want no empty lines between two items, is this what "joinedup" means?) with a margin on the left side, so that the complete itemization is indented. My try is this: ++++++++++++++++++ \starttext \startitemize[joinedup] \item First enumeration. \item Second. \item Third. \stopitemize \startitemize[joinedup, margin=1em] \item First enumeration. \item Second. \item Third. \stopitemize \stoptext ++++++++++++++++++ The first example is without indentation, its fine. But the second example does not work properly, it makes the indentation, but ignores the joinedup, so that one has again empty lines between items. I think "joinedup" is the wrong feature, which is the correct one for my purpose? Huseyin

I try to do it like this: \def\myfootnotecolor#1{% \startcolor[red]#1\stopcolor} \setupfootnotes [numbercommand={\myfootnotecolor}] or \setupfootnotes [foregroundcolor=red] either method has no effect.

Overlapping \starthanging \stophanging with side captions
by Peter Sienkowski 15 Apr '13

15 Apr '13

Hi, I'm trying to have extra explanatory text on the side of figures that is not part of the figure's caption. I can get a single figure to work but am having problems when there are multiple figures one after the other. I'm new to ConTeXT and have looked at the Details Manual but have not been able to fix this. I've been using something like: \starthanging{ \placefigure[force][fig:first]{Caption 1} {\externalfigure[first-figure][width=\textwidth]}} \inother[width=5cm]{Some text for the other bit} \stophanging \starthanging{ \placefigure[force][fig:first]{Caption 2} {\externalfigure[second-figure][width=\textwidth]}} \inother[width=5cm]{Some text for the other bit 2} \stophanging and the two figures will overlap. Any help would be much appreciated. thanks Pete

[***SPAM***] Changing the font of the TOC-Title

Hello, I know, that I can change the TOC-Title by \setupheadtext[content=Whatever the TOC-Title may be] How can I change the Font of the TOC-Title, is there a style key, or somewhat like that?

strange index behaviour with entries inside separatedlist
by WolfgangZ 15 Apr '13

15 Apr '13

Hello, I get wrong list entries when using my register entries inside separate lists. Example case included, even if it is a bit longer. For explanation, I have two lists, the correct index is in section 1.2 in the attached example and printed on page 3 (see test.pdf). The one that causes trouble is set in section 1.3 (green table) and printed on page 5. There the index links to page 4 instead of page 1, on which the entry is placed. The example gets more strange, as the wrong index entries only occurs if there is no regular text below the table in section 1.3. For testing you can uncomment line 70 in file test.tex. I hope anyone can help to explain that functionality. Best regards Wolfgang

arc notation Lucida
by John Kitzmiller 14 Apr '13

14 Apr '13

My primary plea for help is how to make an arc symbol over 3 letters in ConTEXt with lucidaot as body font. In pdfLaTeX I could use package fourier to get such an extensible symbol where \widearc was preferable to \widehat. Hans' new "about" regarding extensible glyphs is suggestive, but because I am kind of a dope, leads me to my secondary call for help: How can I directly enter the 'code' for a LucidaBrightOT character from the tables at TUG: http://www.tug.org/store/lucida/otmath-blocks.pdf and see the result? Or find the name to use in a math $ \symbolname $ environment? Thanks, Kitz

float combinations
by Robert Blackstone 14 Apr '13

14 Apr '13

Dear all, A few days ago (10 April 2013, Vol.106, Issue 25) I posted a question about giving related but not necessarily adjacent floats the same number, as for example Fig. 2a and Fig. 2b. In the meantime I found a, not very elegant, solution that only partly satisfies me. Here is a working example: (I trust the cow and the mill can be found). %--------------------------------------------------- \useexternalfigure[SmallCow][cow.pdf][height=2cm] \useexternalfigure[MediumCow][cow.pdf][height=3cm] \useexternalfigure[Mill][mill.png][height=3cm] \definelist[figure] \setuplist[figure][prefix=yes,label=yes,alternative=c] \starttext This file is for testing the possibility of giving two related musical examples (in old and modern notation respectively) the same figure number with a. and b. as suffixes to the number proper. \placefigure[here][SmallCow1]{A small cow.} {\externalfigure[SmallCow]} A cow again, in two sizes. \in{Figure}[SmallCow2]a shows the same cow as \in{Figure}[SmallCow1]. \placefigure[here][SmallCow2]{{\bf a}. Another small cow.} {\externalfigure[SmallCow]} And here a larger cow (\in{Figure}[MediumCow1]b). \setnumber[figure][1] \placefigure[here][MediumCow1]{{\bf b}. A larger cow.} {\externalfigure[MediumCow]} And here comes a mill. \placefigure[here][Mill1]{A mill.} {\externalfigure[Mill]} \page {\bf List of Figures} \placelist[figure] \completecontent \stoptext %---------------------------------------------------- This way "a" and "b" become part of the caption text, resulting in: Figure 2 a A small ….. etc., and: Figure 2 b A larger …etc. Likewise in the List of Figures. This is not what I would like. Is there a possibility, when not using Combinations, to get: Figure 2a A small ….. etc? Wherever possible I use Combinations but in some cases examples to be combined are very different in size and shape and/or too large to fit on one page together, so that one of them gets cut off. Is there a possibility, when using a combination of figures, to split it, in other words, to separate the figures spatially, to allow them to appear on consecutive pages, and maybe even allowing some text in between? Thanks in advance. Best regards, Robert Blackstone

Read output of external command

Hi, I need to read the standard output of an external command. This is what I came up with: \starttext \startluacode f = io.popen "ls" context(f:read "*a") \stopluacode \stoptext It works with luajittex, plain lua5.1 and lua5.2, but it fails with a current luatex: ! LuaTeX error [string "\directlua "]:3: attempt to index global 'f' (a nil value) stack traceback: [string "\directlua "]:3: in main chunk. Why does this fail in luatex but works in lua5.2 ? What is the correct way to obtain the output of a command? Marco
