Custom metaobj object in context
by Stefan Müller 14 Jul '10

14 Jul '10

Hi, I just tried to build my own object in metaobj but for some reason I cannot figure out it does not work. I tried the example from the metaobj manual in a tex document (it works in a metapost file): \startuseMPgraphic{objecttest} vardef newSegment@#= assignObj(@#,"Segment"); ObjPoint a,b; ObjCode "@#b-@#a=(1cm,2cm)"; enddef; \stopuseMPgraphic When processing this with context (MkIV) I get ! Illegal parameter number in definition of \@MPG@objecttest. <to be read again> = <argument> vardef newSegment@##= assignObj(@##,"Segment"); ObjPoint a,b; Ob... \dostartuseMPgraphic ...leuseMPgraphic {#1}{#2}{#3 }} l.7 \stopuseMPgraphic My first wild guess is that it has something to do with the "evil" @-symbol. But even if this is the case I don't know what to do to fix this. Any help appreciated and thank you very much in advance. Stefan.

Return value of context call
by Marco 14 Jul '10

14 Jul '10

Hi, when there's a mistake in the context code then the context call returns »1«. When there's a mistake in the metapost code then the context call returns »0«. This is annoying for me, since I use the return value as indicator for my pdf reader to refresh. This seems like a bug to me. Is there a workaround? Best regards Marco

change numeral to string in Metafun
by dalyoung 13 Jul '10

13 Jul '10

Dear all, I'd like to draw boxes with a label in a certain rule. I define drawbox macro for it. It receives 3 numbers, (the height of box, x position, y position). I'd like to label the height of the box in the middle of the box. I tired label( h ,(3s*u+u, t*u + h*u/2)); %h is a received numeral. But it is not working. If I change h to "letter" in label command, it is working. So, I'd like to know how to put received numeral(the height of the box) as a label. Or, how to change the value of a variable to a string. Here is a working sample code. \startuseMPgraphic{sample} numeric u; u := 0.5cm; def drawbox (expr h, s, t) = %numeric h,s,t; draw unitsquare xyscaled (1cm, h*u) shifted (3*s*u, t*u); label("1",(3s*u+u, t*u + h*u/2)); enddef; drawbox (3, 0, 0); drawbox (6, 0, 3); drawbox (2, 1, 0); drawbox (1, 1, 2); drawbox (3, 2, 0) drawbox (4, 2, 3) \stopuseMPgraphic \starttext \placefigure[here][]{sample} {\useMPgraphic{sample}} \stoptext Thank you.

Dear ConTeXtuals, the following MP-inclusion produces fatal error (! TeX capacity exceeded, sorry [parameter stack size=6000].): starttext \startMPcode label(btex $\underbrace{a}_{b}$ etex,(0,0)); \stopMPcode \stoptext I use mkii, but the code should work. Has anyone an explanation? With many thanks for any hint Albrecht

\frac with Cambria
by luigi scarso 12 Jul '10

12 Jul '10

\usetypescript[cambria] \setupbodyfont[cambria,8pt] \starttext \inlinemath{\displaystyle\frac{(1-0.1) - 0.89803921568627}{1-0.1}}% {\switchtobodyfont[modern,8pt] \inlinemath{\displaystyle\frac{(1-0.1) - 0.89803921568627}{1-0.1}}} \stoptext IMO the numerator with cambria is too much distant from fraction's line: the same with LatinModern looks better. Denominator looks ok. -- luigi

parsing issue with \math{} inside natural table
by Brian R. Landy 12 Jul '10

12 Jul '10

Hi, I ran into a case where a natural table has an issue when it contains inline math and an alignment character is used. Here's a small example which triggers the problem: \starttext< \bTABLE< \bTABLEbody< \bTR< \bTD[alignmentcharacter={.},aligncharacter=yes]{\le 4.0\math{-}}\eTD< \eTR< \eTABLEbody< \eTABLE< \stoptext< However, if I replace \math{-} with $-$, the file works. Am I correct that $-$ and \math{-} should be interchangeable? Thanks, Brian

Here is a better patch, with new strings translated and v!appendix commented as in lang-ger.tex. I could also add support for Serbian latin, but I have no idea how to add new language that will allow both latin and cyrilic. -- Vedran Miletić
