Layers + simplefonts: Using different font in layers?
by Mari Voipio 09 Dec '11

09 Dec '11

Hi! After a wee bit of struggle I've managed to get as far as to (re)creating front and back covers of a booklet as layers. They worked fine in separate files, but now I have to incorporate the layers into my main file and that turned out to be too complicated for my little brain. Thus I'd appreciate a bit of help... I'm using Windows 7 and SciTe and I just updated my ConTeXt to newest beta (and it works). Problem one: The text on the covers needs to be in Arial, but the contents should be in Candara. I can get this done in totally separate files with \usemodule[simplefonts] \setmainfont[arial] \usemodule[simplefonts] \setmainfont[candara] However, when I put the front cover before the main contents, I don't seem to be able to reset the font. The same goes for \setupinterlinespace, it is 1.8em on the cover and default in the contents. I'm not very familiar with the layers nor the font switching and this together makes it very difficult for me to figure out in what order my commands should be (and what they should be; doing a search on the wiki pages on "setmainfont" gives *no* results). So, can somebody provide me with a minimal example of a file that has a layer with text in one font (preferably using simplefonts) and a few pages of text in another font and then another layer as backcover in cover font? Problem two: Whatever I do, I can't get the final number of pages to be divisible by for (and in a way that the back cover ends up on the last page). I used to use the hack given at <http://wiki.contextgarden.net/Imposition#Getting_to_the_Back_Cover_of_a_Boo…>, but it doesn't work any more (hangs on \fi} / line 18); I think it still worked in June 2011, but not any more in August. So, how do I get my back cover to pop up on the last page of my booklet? (Problem three: Having stuff under back matter causes a few extra empty pages that I don't seem to be able to suppress with any combination of \page commands (last one I tried seems to be \page[right,quadruple]). However, this problem may go away if 1 & 2 get solved.) Thankful for any help, Mari

MetaFun: Is the maximum of `vloggrid` limited to 10?
by Paul Menzel 09 Dec '11

09 Dec '11

Dear ConTeXt folks, the `vloggrid` command is described in section 9 of the MetaFun manual [1]. vloggrid (Min, Max, Step, Length, Height) Can somebody confirm that `Max` can be at most 10? \starttext \type{draw vloggrid(0, 11, 10, 15cm, 5cm);} \startMPcode drawoptions(withpen pencircle scaled .25pt withcolor .5white); draw vloggrid(0, 11, 10, 15cm, 5cm); \stopMPcode \type{draw vloggrid(0, 11, 1, 15cm, 5cm);} \startMPcode drawoptions(withpen pencircle scaled .25pt withcolor .5white); draw vloggrid(0, 11, 1, 15cm, 5cm); \stopMPcode \type{draw vloggrid(0, 11, 5, 15cm, 5cm);} \startMPcode drawoptions(withpen pencircle scaled .25pt withcolor .5white); draw vloggrid(0, 11, 5, 15cm, 5cm); \stopMPcode \type{draw vloggrid(0, 11, 5, 15cm, 5cm);} \startMPcode drawoptions(withpen pencircle scaled .25pt withcolor .5white); draw vloggrid(0, 10, .5, 15cm, 5cm); \stopMPcode \CONTEXT\ \contextmark\ \contextversion \stoptext To create grid like the log-log grid in [2] I guess I need to compose the bigger grid from these “basic” grids then?

naming of labels: Is »()« allowed?
by Paul Menzel 08 Dec '11

08 Dec '11

Dear ConTeXt folks, in ConTeXt I like how I can choose arbitrary names for label and reference them. I think some time ago it was possible to also use »()«. This does not work anymore with ConTeXt ver: 2011.11.25 21:29 MKIV fmt: 2011.11.25 int: english/english and the following message is in the log file. references > unknown reference [][(N)] \definereferenceformat[eqref][left=(,right=)] \starttext \placeformula[(N)] \startformula \Pr\{N = n\} = \Pr\left\{ \min_{1 ≤ k ≤ n} S_k > 0 \right\} = p_n^{(1)} \stopformula Is it working? \eqref[(N)] \CONTEXT\ \contextmark\ \contextversion \stoptext Thanks, Paul

Copyright Symbol
by Malte Stien 08 Dec '11

08 Dec '11

Hi everyone, How do I get a copyright symbol in ConTeXt, you know the circle with the 'C' in the centre? I expected it to be \textcopyright as in LaTeX, but that does not seem to work. Rather than just telling me the answer, where would I look that up? Sooner or later I will need other symbols. The special characters listed in the manual are quite limited. Is there a list somewhere? Thank you, Malte.

Columnset error with \setupheader[state=high]
by Peter Park Nelson 08 Dec '11

08 Dec '11

Update: I don't have a solution yet, but here is my attempt to figure out where this problem comes from. I may be (probably am) wrong; I am new to ConTeXt and not an expert on its internals. But I'll toss this out to see if anyone is interested. When \startcolumnset is called, it seems to take a "snapshot" of the state of the layout (via setuplayout). However, layout can change, even without \setuplayout being explicitly called again, as in the case of header state=high (which modifies the layout of the first page only). By visual inspection, it looks like the columnset output routine continues to use the page dimensions from the first page on subsequent pages. Since the first page has no header space, height of the text box on the first page will be larger than on subsequent pages. Therefore, applying the first page height on subsequent pages will result in text that runs over the footer area. To see if a new call to \startcolumnset would fix things, I tried to find a way to automatically do \startcolumnset again at the beginning of the second page. A crude hack, using the startpostponing mechanism: \startpostponing[2] % do this block on the second page \unexpanded\stopcolumnset\unexpanded\startcolumnset[name] % manually end the current columnset and then start it again. \stoppostponing This unfortunately results in a blank page after the first page; however, the rest of the pages after that blank page have correct columnsets and footers. So a real solution to this problem could perhaps be done in two different ways -- the difference being where in the ConTeXt code it is implemented: A. The columnset output routine "listens" for changes in the layout state and reloads or adjusts itself when layout state changes; or, B. Any change in layout state passed to the output routine triggers a re-call of the \startcolumnset macro. These are probably oversimplified, but I hope someone who understands the columnset output routine can see what I am trying to get at. -- Peter Park Nelson peter.park.nelson(a)gmail.com

math: root sign an square brackets set too closely

Dear ConTeXt folks, using the root sign √ `\sqrt` and the square brackets [] the distance does not seem to be optimal. \starttext \type{$\left[ \sqrt{x} \right]$}: $\left[ \sqrt{x} \right]$ Without \type{\left} and \type{\right}: $[\sqrt{x}]$ \type{$\left( \sqrt{x} \right)$}: $\left( \sqrt{x} \right)$ With \type{\,}: \type{$\left[ \sqrt{x}\, \right]$}: $\left[ \sqrt{x}\, \right]$ \placeformula \startformula \left[ \sqrt{x} \right] \stopformula \CONTEXT\ \contextmark\ \contextversion \stoptext I am using the following version.

Re: [NTG-context] Tikz/pgf colour issue
by Felix Ingram 07 Dec '11

07 Dec '11

Further investigation suggests that this is a known issue of using \definecolor colours within a Tikz graphic that decided to manifest itself for the first time when I upgraded. The solution is to do: \unprotect \pgfutil@definecolor{colour_name}{rbg/cmyk/gray}{...colour values...} \protect for all the colours that you want to use. Apologies for the noise. Felix
