[metapost] troubles with labels
by Pol Stra 29 Dec '13

29 Dec '13

Dear all, with this minimalist content of metapost file: ``` beginfig(1); dotlabel.ulft("A", origin); endfig; end. ``` And this conteXt file: ``` \starttext \startMPrun input mymp.mp; \stopMPrun \externalfigure[mprun.21][width=5cm] \stoptext ``` The resulting pdf file contains no figure. But this conteXt file works: ``` \starttext \startMPcode dotlabel.ulft("A", origin); \stopMPcode \stoptext ``` As with any metapostfile which does not contain labels. But as soon as there is label, their is no figure. Two last things: if I compile the metapost file with standalone metapost, I can include the resulting file as an external figure. But if I put a label "A'", while with displaying figure with a viewer it is ok, when included in a conteXt file, I only obtain "A" label. Also, if I try to change the font in the metapost file (for example defaultfont:="pplr8r";) it does not work in conteXt. Do you have an explanation or workaround? Thank you

boxedcolumns weirdness
by H. van der Meer 29 Dec '13

29 Dec '13

I am typesetting a series of items with boxedcolumns enclose in a framedtext: \startframedtext[width=\makeupwidth,offset=0pt,frame=off,align=tolerant] \startboxedcolumns[n=2,separator=rule] Occasionally it happens that material at the end of the first column is not typeset. It occurs haphazardly in a large (more than 300) series of items. Depending on the length of the first columns material (I introduced extra space with \crlf, \blank, \blank[dimension]) other items exhibit the effect. Because of this haphazard character, the large data set and the fact that I could not isolate it in a few items, I regrettably do not have a minimal example. Thus I can only signal it here, in case others encounter it too. Or in case the person maintaining this code happens to spot the problem from the observation alone.

Centering the last line in combination subcaptions
by Jan Tosovsky 27 Dec '13

27 Dec '13

Hello Everyone, I try to fill the entire page with two images with their captions. The final page should be floating, keeping both images together and not containing any other text. I found this solution. It work fine for short captions / wide images. \starttext test \startplacefigure[location=page, number=no, title={}] %\setupcombinations[align={hz, hanging}] %\setuptolerance[strict] {\startcombination[1*2] {\externalfigure[cow]} {\input{ward}} {\externalfigure[cow]} {\input{ward}} \stopcombination} \stopplacefigure \stoptext If captions are long and the image narrow, they are typeset on multiple lines. Default centering produces the ragged column - both not very nice and difficult to read. When the alignment is set to hanging, it looks better except the last line which is not centered. Is there any settings for centering the last line? Can the 'column' width be somehow extended to e.g. 80% of text width? If not via the 'combination', are there any better alternatives for my use case? Any hint is appreciated. Thanks, Jan

underbrace under stacked math error with latest beta (2013.12.26)

A minimal example: --------------- cut -------------------- \def\2#1#2{\vcenter{\halign{\hfil ##\hfil\cr #1\cr#2\cr}}} \def\ptwo#1#2{\left(\2{#1}{#2}\right)} \starttext \startformula \underbrace{\ptwo{specific}{heat}}_{1} \stopformula \stoptext --------------- cut -------------------- It works with 2013.05.28 00:36 MKIV current, correctly producing ( specific ) heat (with bigger parens) with an underbrace and a 1 underneath the brace. With 2013.12.26 12:50 MKIV beta, I get this error: !

\quotation with yfrak-font?
by Rudolf Bahr 27 Dec '13

27 Dec '13

In the following minimal example I'd like to get quotation marks around the "Nein!", but I don't: ------------------------------------------------------------ \starttext \language[de] \pdfmapline{yfrak <yfrak.pfb} \definefont[YfrakFont][yfrak at 11pt] \YfrakFont Zu meinem Vorschlag sagte das: M*adchen: \quotation{Nein!} \stoptext ----------------------------------------------------------- Please, what is wrong? I fear Wolfgangs suggestion wouldn't work either in the yfrak case: ----------------------------------------------------------- \starttext \symbol[leftquotation]Left \symbol[leftquote]middle\symbol[rightquote] right\symbol[rightquotation] \language[de] \symbol[leftquotation]Left \symbol[leftquote]middle\symbol[rightquote] right\symbol[rightquotation] \pdfmapline{yfrak <yfrak.pfb} \definefont[YfrakFont][yfrak at 11pt] \YfrakFont \setuplanguage [de] [leftquote=›, rightquote=‹, leftquotation=», rightquotation=«] \symbol[leftquotation]Nein! \symbol[leftquote]Nein!\symbol[rightquote] Nein!\symbol[rightquotation] \stoptext ----------------------------------------------------------- As context version I'm using: ConTeXt ver: 2013.06.10 22:51 MKIV beta fmt: 2013.6.21 int: english/english Rudolf

doublestroke
by Elspeth McGullicuddy 26 Dec '13

26 Dec '13

Hi, I'm writing math and I'm using "modern", and I would like to use "doublestroke". There is an example here, http://www.ntg.nl/pipermail/ntg-context/2008/037124.html, but I think it's not likely to work since families aren't used anymore. I really can't think how it should be done, and all I've found would be through some substitution mechanism as described in "fonts-mkiv.pdf". I could use an example of replacing a "vector" of a font, by another font. There might be things too with "simplefonts" and "fallback" mechanism, but I haven't seen examples with math. Regards, Chris

pdf format
by H. van der Meer 26 Dec '13

26 Dec '13

In the past, when viewing the pdf produced by ConTeXt in the viewer of my browser (Safari) there is shown one page at a time. Old ones still do this. But pdf produced nowadyas is different, 4 pages appear in the browser window. The same happens for example looking at the latest LuaTeX manual. Has something changed in pdf production? Perhaps some parameter that the Adobe-plugin of the browser lets show the pdf that way? And if this is indeed the case, how can I get the original behaviour of one page per view back?

Rebuilding the font cache: segmentation fault 11
by Willi Egger 25 Dec '13

25 Dec '13

Hello all, did anyone else experience this: fonts | names | globbing path '/Users/willi/Library/Fonts/**.ttf' fonts | names | globbing path '/Library/Fonts/**.ttf'Segmentation fault: 11 I struggle with this issue since I stepped over to a new Mac book Air. Is there something tricky in the Library/Fonts directory? May be a subfolder could cause this? Kind regards Will

Request for metapost
by DesdeChaves 25 Dec '13

25 Dec '13

I know that metapost can send the variables "version", "number", "string", "point", "quad", "boolean" and "path" to Context. "triplet" variable can't pass. It will be very usefull if metapost can send a array to context. \startMPcode numeric x[]; for i = 1 upto 10: x[i]:=random; endfor passvariable("array",x); passvariable("version","1.0") ; passvariable("number",x[1]) ; passvariable("string","whatever") ; passvariable("point",(1,2)) ; passvariable("triplet",(1,2,3)) ; passvariable("quad",(1,2,3,4)) ; passvariable("boolean",false) ; passvariable("path",fullcircle scaled 1cm) ; \stopMPcode \ctxluacode{inspect(metapost.variables)} \ctxcommand{mprunvar("array")} Thanks in advance Jorge
