Differences for \Vert in mkii and mkiv
by Otared Kavian 02 Feb '11

02 Feb '11

Dear Aditya, dear Hans, I noticed a serious difference between what one gets for \left\Vert in mkii and in mkiv. Probably this is due to the fact that in mkiv the glyph for \Vert is constructed in a different manner, but as far as I know from what I see in the mathematical printed materials, the correct one, or the expected one, is the output from mkii. I join two small PDF files obtained with the typesetting of the following minimal example: %%% begin test-Vert.tex \let\|=\Vert \starttext Look at the differences between mkii output and that with mkiv: \startformula \left\Vert\int_0^1 G(\cdot,s)ds\right \|_{L^q} \lesssim \|G\|_{L^p}. \stopformula \stoptext %%% end test-Vert.tex Is there a way to redefine locally \Vert (or \|) so that in mkiv one gets the same output as with mkii? Thanks in advance: OK

\date format according to ISO 8601
by Marco 01 Feb '11

01 Feb '11

Hi, in my opinion it makes sense to display the date in ISO 8601 format. now: \date results in: January 31, 2011 ISO 8601: \date would result in: 2011–01–31 In case Hans does not like this idea, is it possible to change it to make ISO 8601 the default. Something like \setupdate [format={year, –, mm, –, day}] Regards Marco

beta
by Hans Hagen 01 Feb '11

01 Feb '11

Hi, I uploaded a beta. Tho most important change is that mkii and mkiv are now completely separated, only a couple of modules and styles are shared. Another change is that language related information is now organized differently. Labels and such are in lang-txt.lua and easier to maintain. For those writing pretty printers: pluggable code is now under xxxx-imp-* i.e. the imp subnamespace. I have considered -base, -user etc but that would lead to too much testing. Users can put their extensions (when part of third party modules) under for instance buff-imp-t-<somename> which is unique enough. Anyway, by using an additional -imp- we have less change of clashing with core modules. Some more will probably follow. Hopefully all files are in the zip.

TTF fonts and MKIV
by John Culleton 01 Feb '11

01 Feb '11

Is there a short, simple guide somewhere that shows how to use TTF and OTF fonts in Context? I downloaded the new Fonts chapter but it goes deep into the weeds on typescripts etc. I am looking for a method that allows me to do in Context what I can already do in most other DTP programs: simply designate for use a font or font family that exists in /usr/share/fonts without typescripts, complex and confusing aliasing schemes or tfm files. -- John Culleton Create Book Covers with Scribus: http://www.booklocker.com/p/books/4055.html Typesetting and indexing http://wexfordpress.com book sales http://wexfordpress.net Free barcode: http://www.tux.org/~milgram/bookland/

prevent gobbling of spaces when omitting optional argument
by Florian Wobbe 01 Feb '11

01 Feb '11

Hi, please consider the following minimal example: \def\before{\dodoubleempty\dobefore}% \def\dobefore[#1][#2]{before} \starttext \before[] after (should be: \before[]\ after without explicit \type{\ })\par \before[]after\par \before[][] after\par % this works \before[][]after\par \stoptext How can I prevent gobbling the following space, when the second optional argument is not given (i.e. first line). The macro itself should not insert space if the command is followed by any other character (2nd and 4th line). Thanks, Florian

showing and hiding layers
by Skip Collins 01 Feb '11

01 Feb '11

I am trying to create a layer to contain letterhead graphics. I would like the letterhead to appear by default when a pdf is opened and printed. But I would also like to be able to hide the letterhead layer in Acrobat when printing on pre-printed paper. My simplistic, always-displayed letterhead looks like: %%% start code %%% \definelayer[letterhead] [x=0in,y=0in,width=\paperwidth,height=\paperheight,state=start] \setlayer[letterhead] [hoffset=1in,voffset=0.5in] {LetterHeadMark} \setupbackgrounds[page][background={letterhead}] \starttext Hello, World! \stoptext %%% stop code %%% But there is no obvious way to turn this off when printing. Contextgarden suggests using \defineproperty to create a pdf layer. I can show and hide this layer in acrobat, but it always opens up hidden. I am also not sure how to place the letterhead exactly on the page using this method. Any suggestions?

Too many column gaps in TABLE
by Stefan Müller 31 Jan '11

31 Jan '11

Hi list, please consider the appended example. I get a gap in the first row after the first column because of the \setupTABLE command. However, I also get a gap after the second column, because in the second row the first cell just ended. Can this be considered a bug? (Mk IV) If it's not a bug, how can I change this behavior? I only want to have one gap right after the first cell in the first row and no other gaps between the columns (so the second row shall have no gap at all). Do I have to insert a dummy column with "width=1em" after the first cell and change "nc=2" to "nc=3"? Thanks in advance! Stefan \starttext \setupTABLE[c][1][distance=1em] % Both \setupTABLE commands yield the same %\setupTABLE[1][1][distance=1em] \bTABLE \bTR \bTD gap after this column \eTD \bTD two \eTD \bTD we don't want a gap \eTD \eTR \bTR \bTD[nc=2] first cell in second row \eTD \bTD \dots before the third column \eTD \eTR \eTABLE \stoptext

startMPgraphic?
by Hans van der Meer 31 Jan '11

31 Jan '11

I just started the conversion of my presentation sheets to ConTeXt mkIV. As could be expected, some inconsistencies will turn up. However this one escapes me. What I am missing that \startMPgraphic results in ! Undefined control sequence. I thought that installing the minimals of ConTeXt-beta also installed the metafun module. Or has this one macro been deprecated? Hans van der Meer
