linear_shade not working any more
by Mojca Miklavec 19 Jul '06

19 Jul '06

Hello, It seems to me that the following code worked in some beta 2 weeks ago: \setupcolors [state=start] \definecolor [BgColor1] [white] \definecolor [BgColor2] [r=0.7,g=0.7,b=1] \starttext \startMPcode path p; p := unitsquare scaled 3cm; linear_shade(p,0,\MPcolor{BgColor2},\MPcolor{BgColor1}); \stopMPcode \stoptext But with 2006.07.14 I get: This is MetaPost, Version 0.901 (Web2c 7.5.3) (shading-mpgraph.mp >> (1,0,0) ! Isolated expression. <to be read again> ; scaledgray->begingroup.red; endgroup l.286 ...(scaledrgb(0.7,0.7,1,1)),(scaledgray(1,1) )); ? Any suggestions about what could go wrong? Thank you, Mojca

prevent hyphenation (flush left)
by Mojca Miklavec 19 Jul '06

19 Jul '06

Hello, I urgently need to have my \framed texts left-justified (no hyphenation and nothing may go over the right border) I know that it must be trivial, but I assume that explicit \exhyphenpenalty=10000 \hyphenpenalty=10000 are replaced inside \framed anyway. Thank you, Mojca

strange font switching (bug?)
by Mojca Miklavec 19 Jul '06

19 Jul '06

Hello, can anyone explain this weird behaviour? The accents on the second page are broken (setting bodyfont to 7pt at the beginning works OK and using other sizes works as well.). \setupbodyfont[8pt] \startsetups{img} \switchtobodyfont[7pt] \stopsetups \starttext \ccaron\scaron\zcaron \page \setups{img} \ccaron\scaron\zcaron \stoptext Thank you very much, Mojca

A page for figures ?
by Renaud AUBIN 19 Jul '06

19 Jul '06

Hi all, I would reserve a page for several figure (i.e. \placefigure). \placefigure[page] reserve ONE page for ONE figure... Can \placefigure reserve a page for several figures with an option I don't know yet ??? Since I assume \placefigure can do that for me, I don't want to use \placefigure[page]{none}{\startcombination...\stopcombination}... ;) TIA Renaud

2006.07.13 release notes (MP-related)
by Renaud AUBIN 18 Jul '06

18 Jul '06

Hi all, First, I don't understand this part of the release notes: "supp-mps.tex: * \startuseMPgraphic and \startusableMPgraphic no longer have an argument" Does it mean that we don't have to use \startuseMPgraphic{myMPgrapharg} ... \stopMPgraphic with any myMPgrapharg ? I assume I've missed something... :-\ Second, what's the difference between staticMPfigure and staticMPgraphic and how (and where) can we use it ? Some advice are welcome in this part because I use a lot of MPgraphic and I'm really interested to use staticMPXXX if I can save some processing time... ;) Last but not least: I've posted some days ago a thread "[NTG-context] A page for figures ?"... This problem is always topical... Cheers, Renaud

small new feature on the wiki
by Patrick Gundlach 18 Jul '06

18 Jul '06

Hi there, since there might be some users here who edit pages on the wiki and who don't read the 'recent changes' page: you can now say <context source="yes" text="produces"> \your \TeX \code=here </context> this will typeset the source with the <texcode>....</texcode> highlighter/formatter, then output the (optional) text 'produces', and finally renders the already known graphical representation of the source. This way you only have to enter the code once (less errors). Special thanks to Jano Kula for this. Example at http://wiki.contextgarden.net/Right_and_left Patrick -- ConTeXt wiki and more: http://contextgarden.net

align question
by David Arnold 18 Jul '06

18 Jul '06

On another matter, I'm having some alignment issues. Consider the following code: \starttext \startformula \startalign[n=4,{left, middle, middle, middle}] aaa&b&cccc&d\\ a&bbb&c&ddd \stopalign \stopformula \stoptext Compile this and you will notice that the alignment parameters {left, middle, middle, middle} are ignored. And you can change these to anything else (left, middle, right), with absolutely no change. Any idea what is going on here?

Losing Chapter Number
by David Arnold 18 Jul '06

18 Jul '06

Hans et al, Why do we lose the chapter number in headers (and other places) with this: \setupwhitespace[medium] \setupindenting[medium,yes] \def\headermarkleft{\bold{\pagenumber}\headerskip{\sc\headerskip Chapter \headnumber[chapter]\headerskip\getmarking[chapter][current]}} \def\headermarkright{{\sc{}Section \headnumber[section]\headerskip \getmarking[section][current]}\headerskip\bold{\pagenumber}} \def\headerskip{\hskip 1em} \setuppapersize[letter][letter] \setuplayout [backspace=120pt, cutspace=80pt, topspace=50pt, bottomspace=50pt, leftmargin=65pt, rightmargin=50pt, width=middle, header=40pt, footer=40pt, height=middle] \setupheadertexts [] [\headermarkright] [\headermarkleft] [] \setuppagenumbering [state=start, alternative=doublesided, location=, way=bytext] \setupheadnumber[chapter][-1] \starttext \chapter[chap:0]{Preliminaries} \input tufte \section{One} \dorecurse{3}{\input tufte\par} \section{Two} \dorecurse{3}{\input tufte\par} \stoptext

sometxt vs textext behaving different
by Hans van der Meer 18 Jul '06

18 Jul '06

Metapost problem: It seems that sometxt and textext behave different. This is my macro: % Label with text and centerposition vardef theLabel@#(expr labeltext, pos) = save pic; picture pic; if picture labeltext: pic := labeltext; else: if labeltext = "": pic := nullpicture; else: % prevent wobbling of text boxes with uneven depth % TEXTEXT line: pic := textext("\setbox0=\hbox{"&labeltext&"}\dp0=0pt\box0"); % since ConTeXt 14-7-2006 textext => sometxt % SOMETXT line: %pic := sometxt("\setbox0=\hbox{"&labeltext&"}\dp0=0pt\box0"); fi fi % calculate labelshift from suffix save shift; pair shift; shift = ((penX/2 + labeloffset) * xpart laboff@#, (penY/2 + labeloffset) * ypart laboff@#) - (labxf@# * lrcorner pic + labyf@# * ulcorner pic + (1 - labxf@# - labyf@#) * llcorner pic); % deliver picture shifted in position pic shifted (pos + shift) enddef; With textext enabled it just works as I intend. With sometxt enabled I get: >> unknown picture pic >> sometxt ! Equation cannot be performed (unknown picture=numeric). <to be read again> ( theLabel->...":pic:=nullpicture;else:pic:=sometxt( "\setbox0=\hbox{"& (EXPR3)&... l.211 Label("TEXTEXT", (w/2,h/2)) withcolor red; Thus while textext delivers a picture sometxt does not. This seems strange, because I understood that sometxt was meant as a dropin replacement for textext (except for MP loops, as Hans Hagen mentioned in a previous email). Is this correct or do I have to make more changes to switch over from textext to sometxt? Hans van der Meer

formula block with align and pagebreak
by Tobias Burnus 18 Jul '06

18 Jul '06

Hello, I have often longer equations of the type \startformula\startalign A = b c B = c d E = g h \intertext{Some intermediate text} F = h j G = k l \stopformula\stopalign I would like to keep the alignment (per page), however I also would like to have automatic page breaks inbetween. I can split it manually into two \startformula\startalign ... \stopformula\stopalign blocks, but this I would have to adapt any time I change something, which changes the text length, before that block. Any idea? Additional question: Does anyone know why in the example the "Gauss' law" starts not at the top of the page but roughly two line further down? Tobias PS: I attached an example.
