Hi, the last beta includes the chapter number in formulas, former betas didn't. Example: \starttext \startchapter [title=Foo] \startplaceformula \startformula E=mc^2 \stopformula \stopplaceformula \stopchapter \stoptext ∙ Is this intended? ∙ How to remove the chapter number from the formula? Marco

Dear all, There is a problem with \useMPlibrary[txt] at compilation time (ConTeXt ver: 2012.09.11 20:36 MKIV): metapost > loaded: library 'txt' (/opt/context-minimals/texmf-context/tex/context/base/meta-imp-txt.mkiv !

Wrong spacing in \unit
by Marco Patzer 17 Sep '12

17 Sep '12

Hi, when \unit is used just with a unit, without a number, the spacing at the left is wrong. Example: \starttext % wrong spacing (\unit{micro mol per second}) % spacing OK (\unit{3 micro mol per second}) \stoptext Marco

MKII & MKIV difference between \textrule
by Alessandro Perucchi 16 Sep '12

16 Sep '12

Hello, In my experimentation, I've found that in mkii and mkiv the behavior of \textrule and \setuptextrule are different... What I did was quite simple: \textrule{Testing head} blah blah blah \textrule in mkii the text in well centered between the lines. But in mkiv the bottom line is too near the text, and I need to add something like \blank[halfline] to have a similar behavior as mkii. And apparently the command \starttextrule ... \stoptextrule doesn't work (this was explain in the cont-entp.pdf page 204) in either mkii & mkiv. Am I missing something? Sincerely yours, Alessandro

\everymath
by Rogers, Michael K 16 Sep '12

16 Sep '12

I often want every math mode (between single $) be \displaystyle. In Plain TeX, you do something like \everymath={\displaystyle} Is the best ConTeXt way to do something like this? \appendtoks\displaystyle\to\everymathematics Or is there a key in \setupmathematics?

\items is buggy in mkiv
by Otared Kavian 15 Sep '12

15 Sep '12

Dear Hans, I noticed that with the latest version of mkiv (ConTeXt ver: 2012.09.10 00:57) the command \items[location=bottom] does not behave as usual (in mkii the bejaviour is correct) Minimal example: \starttext \items[symbol=8,n=5,width=\hsize,location=bottom]{png,eps,pdf,jpg,tif} \blank \items[symbol=8,n=5,location=bottom]{png,eps,pdf,jpg,tif} \stoptext Best regards: OK

View all numbers of sub(...)section
by Jaroslav Hajtmar 15 Sep '12

15 Sep '12

Hello ConTeXist. Is there possibility view all subsubsection number (ie in format 2.3.4 - it mean with section and also subsection number) without \section{} and \subsection{} command using previously? I need to start a separate section number from a certain number (inserted into an existing document) Thanx Jaroslav Hajtmar Here is my example: \setupheadnumber[section][2] \setupheadnumber[subsection][3] % \setupheadnumber[subsubsection][4] % \setuppagenumber[number=234] \starttext %\section{} % I can't view section here %\subsection{} % I can't view subsection here too \subsubsection{TEST} I would like get 2.3.5 TEST blablabla \stoptext

Fortunatly I’m using GNU/Linux. >> cat foo.eps | sed -e "s/0 0 0 setrgbcolor/1 1 1 setrgbcolor/g" > bar.eps >It simply translates the (0,0,0) triplet (which is black) to the (1,1,1) triplet (which is white). This is very simplistic and may not do all that you want. Unfortunatly there is no such a sequence in my file: grep setrgbcolor a1.EPS /setcmykcolor{1 sub 4 1 roll 3{3 index add neg dup 0 lt{pop 0}if 3 1 roll}repeat setrgbcolor pop}wd /sw/setlinewidth ld/scap/setlinecap ld/sj/setlinejoin ld/sm/setmiterlimit ld/sd/setdash ld/rgb/setrgbcolor ld/crgb/currentrgbcolor ld/cmyk/setcmykcolor ld/gs/gsave ld/gr/grestore ld But thank you for gave a try.
