line numbers in header
by Pablo Rodríguez 23 Jan '12

23 Jan '12

Hi there, I'm trying to get a header that contains the numbers of first numbered line on each page and the number of the last numbered line on that page. This is especially useful for poetry. Here is a minimal sample of what I'm trying to do: \setupheadertexts[line--numbers] \starttext \startlinenumbering \dorecurse{50}{\input knuth\par} \stoplinenumbering \stoptext What should I add instead of "line--numbers"? I have tried to search in the reference on the reference manual and the wiki, but I didn't find anything that could help. Many thanks for your help, Pablo -- http://www.oudeis.tk

Centring rotated float
by Marco 23 Jan '12

23 Jan '12

I discovered some problems centring a float which is rotated using externalfigure. Without rotation everything is fine. However, when the orientation option is provided, the frame doesn't match the figure any more and the centring gets lost. Using the dedicated rotation command works. Example: \starttext \startbuffer [fig] \useMPlibrary [dum] \starttext \startTEXpage \externalfigure [placeholder] [width=10cm, height=4cm] \stopTEXpage \stoptext \stopbuffer \savebuffer [fig] [fig] \executesystemcommand{context --purge \jobname-fig.tmp} \startplacefigure [title={Centred, but not rotated}] \externalfigure [\jobname-fig] \stopplacefigure \page \startplacefigure [title=Not centred and wrong frame location] \externalfigure [\jobname-fig] [orientation=90, frame=on] \stopplacefigure \page \startplacefigure [title=Why is this one placed on the left?] \externalfigure [\jobname-fig] [orientation=89, frame=on] \stopplacefigure \page \startplacefigure [title=Still not centred and wrong frame location] \midaligned{\externalfigure [\jobname-fig] [orientation=90, frame=on]} \stopplacefigure \page \startplacefigure [title=This one works] \rotate[rotation=90]{\externalfigure [\jobname-fig]} \stopplacefigure \stoptext Is this a bug? Used version: context 2011.11.29 23:11 Doesn't compile at all using: context 2012.01.16 18:33 Marco

issue with \setuplabeltext
by Pablo Rodríguez 23 Jan '12

23 Jan '12

Hi there, I have the following sample code: \mainlanguage[agr] \usemodule[simplefonts][size=11pt] \setmainfont[Theano Didot] \setuplabeltext[chapter=Ῥαψωδία~] \setuphead[chapter][align=center] \starttext \completecontent \chapter{\mbox{}} \startlines Μῆνιν ἄειδε, θεά, Πηληιάδεω Ἀχιλῆος \stoplines \stoptext And I have just accidentally discovered that label text is only shown in the chapter title, if the \mainlanguage is different from [agr]. (I haven't checked all languages, but it works with la, en, ru and es.) I'm using MkIV from TL2011 and I don't know whether there is a newer command. By the way, how can I make that the Contents have also the chapter label text? Thanks for your help, Pablo -- http://www.oudeis.tk

Wandering floats
by Felix Ingram 23 Jan '12

23 Jan '12

Hello all, I've noticed some strange behaviour with Tikz/PGF in floats. The following example should demonstrate it: \usemodule[tikz] \definefloat[newfloat][newfloats] \setupfloat[newfloat][ rightmargindistance=1cm, maxwidth=0.5cm, ] \startbuffer[myfloat] \placenewfloat[right, none, fit]{}{ \starttikzpicture \node[text width=2cm] {% \color[black]{\tfx\bf I'm the Doctor. Well, they call me the Doctor. I don't know why. I call me the Doctor. I don't know why. } }; \stoptikzpicture } \stopbuffer \starttext \getbuffer[myfloat] Saving the world with meals on wheels. No, I'll fix it. I'm good at fixing rot. Call me the Rotmeister. No, I'm the Doctor. Don't call me the Rotmeister. No… It's a thing; it's like a plan, but with more greatness. I'm the Doctor, I'm worse than everyone's aunt. *catches himself* And that is not how I'm introducing myself. Heh-haa! No, I'll fix it. I'm good at fixing rot. Call me the Rotmeister. No, I'm the Doctor. Don't call me the Rotmeister. \page \getbuffer[myfloat] Saving the world with meals on wheels. No, I'll fix it. I'm good at fixing rot. Call me the Rotmeister. No, I'm the Doctor. Don't call me the Rotmeister. No… It's a thing; it's like a plan, but with more greatness. I'm the Doctor, I'm worse than everyone's aunt. *catches himself* And that is not how I'm introducing myself. Heh-haa! No, I'll fix it. I'm good at fixing rot. Call me the Rotmeister. No, I'm the Doctor. Don't call me the Rotmeister. \stoptext The first float will be placed nicely in the right margin up against the text. The second, however, will be shifted into the margin. Can anyone suggest anything? I'm not sure how to go about debugging this. I believe it is another example of the shifting PGF graphics that others (and I) have seen since upgrading to a new beta (I believe this changed sometime since version 2011.11.29). Any help appreciated, Felix

\startitemize[columns] broken with backgrounds?
by Otared Kavian 23 Jan '12

23 Jan '12

Hi all, It seems that when using background, \startitemize[columns] does not work as expected: there are no columns, and the numbers of the items are pushed to the left. Below is a not so minimal example: the resulting PDF can be found here: http://dl.dropbox.com/u/4316076/enumeration-background-exo.pdf I am not sure whether this behaviour began with a recent beta or not.

file with too many radial shadings
by Pablo Rodríguez 22 Jan '12

22 Jan '12

Hi there, some months ago I discovered that one file generated with LuaTeX + ConTeXt was too slow using mupdf (a PDF viewer). So I filed a bug (http://bugs.ghostscript.com/show_bug.cgi?id=692500) and one of the developers replied that the file contained too many radial shadings, most of which were identical. I wonder whether this bug still affects to current releases from LuaTeX and ConTeXt. Just in case it might help, Pablo -- http://www.oudeis.tk

sectioning command with no title
by Pablo Rodríguez 22 Jan '12

22 Jan '12

Hi there, I'm trying to get the opposite command to title, that is, numbering with no text. What would it be the best command? I thought \section{~} or \section{\mbox} could do the job, but I wonder whether they might add something that would prevent perfect [align=center] in the title. Thanks for your help, Pablo -- http://www.oudeis.tk
