Columnset error with \setupheader[state=high]
by Peter Park Nelson 09 Dec '11

09 Dec '11

Hello, I hope someone has solved this problem already but I haven't been able to find a solution. When using \setupheader[state=high], my columnset behaves correctly on the first page but runs over the footer area on all subsequent pages. If I do not use state=high (i.e. normal header on first page) the columnset works correctly. However I need to get rid of that first page header. The result is the same if I set state=high using \setuphead[title][header=high]. I found a mention of this in a forum thread from 2006, but no solution: http://www.ntg.nl/pipermail/ntg-context/2006/018535.html: >Ehrt, Michael wrote: >>* *>*> Do you know if the column text overrunning the footer when using*>*> state=high is a general problem or "just me"?

Any help will be appreciated, PPN -- Peter Park Nelson peter.park.nelson(a)gmail.com

`\{start, stop}MPpage`: MetaPost figure does not fit canvas(?) in resulting PDF file
by Paul Menzel 09 Dec '11

09 Dec '11

Dear ConTeXt folks, using the following example \starttext \startMPpage draw (0,0)--(10,10)--(15,5)--(20,10); draw (0,0)--(0,10)--(10,10)--(10,5)--(15,5)--(15,10)--(20,10) withcolor blue; \stopMPpage \stoptext it looks like the bottom is not included in the resulting PDF file and at the top there is too much room. (So it looks like the figure is moved too far to the bottom.) Using the examples from the Wiki [1] with circles works though. I am using ConTeXt Standalone.

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.
