doifnumberelse
by Hans van der Meer 03 Mar '10

03 Mar '10

The macro \doifnumberelse is not behaving as I would have expected from the description in Taco Hoekwater's article "Context System Macros: part 1: General macros". There I read: The next macro executesa command depending of the outcome of a test on numerals. \doifnumberelse {string} {then ...} {else ...} This text suggest that the the test is on whether "string" as a whole is a number (taken as having digits 0123456789 only, I presume) of contains nondigits and thus isn't a number. However, it seems the macro tests on the first character only. Below follows a minimal example, the context version is: ConTeXt ver: 2010.02.18 14:48 MKIV fmt: 2010.2.20 int: english/ english % test result of \doifnumberelse \def\test#1{#1 is \doifnumberelse{#1}{a number}{not a number}\crlf} \starttext \test{1} % result: 1 is a number \test{a} % result: a is not a number \test{1a} % result: 1a is a number \test{a1} % result: a1 is not a number \stoptext Hans van der Meer

Blank page at end of chapter

I can't figure out how to turn off running headers on the blank pages that are inserted into a document to make the first page of the next chapter start on a right page. I'm probably overlooking something. Tom Benjey 717-258-9733 voice 717-243-0074 fax Twitter: @TomBenjey

METAPOST's superellipse with superness<0.5 does not give a superellipse
by James Fisher 02 Mar '10

02 Mar '10

Hi again, Another METAPOST problem. For the sake of curiosity, I've been looking at and playing with the superellipse() function in plain METAPOST. This is all fine and dandy until I try values of 'superness' less than 0.5, in which case it generates shapes that are seemingly not superellipses. At s=0.5, the function generates a diamond shape -- which, AFAIK, is correct. However, s<0.5, the points of the diamond immediately turn to curves. (My knowledge of superellipses here is just from http://en.wikipedia.org/wiki/Superellipse -- try the image at http://en.wikipedia.org/wiki/File:Lame_anima.gif to see how I expect the shape to change with varying values of superness). Some code follows -- perhaps someone could run it and tell me if, for starters, they get the same as me. (See http://i49.tinypic.com/2ijqatl.jpgfor superellipse() with s=0.3). Best, James % The following is a superellipse function at < http://lists.foundry.supelec.fr/pipermail/metapost-commits/2008-June/000340… >; % I think it's the superellipse function in my copy of METAPOST; it at least has the same behaviour. % It seems to calculate the vertices correctly, but not the way they join (try changing all ... to --). % %def superellipse(expr r,t,l,b,s)= % r ... (s[xpart t,xpart r],s[ypart r,ypart t]){t-r} ... % t ... (s[xpart t,xpart l],s[ypart l,ypart t]){l-t} ... % l ... (s[xpart b,xpart l],s[ypart l,ypart b]){b-l} ... % b ... (s[xpart b,xpart r],s[ypart r,ypart b]){r-b} ... cycle %enddef; def supertest expr s = superellipse( ( 100, 50 ), ( 50, 100 ), ( 0, 50 ), ( 50, 0 ), s ); enddef; % These >0 supernesses are fine, I think ... beginfig(0); draw supertest 2; endfig; beginfig(1); draw supertest 1.01; endfig; % The following, 0.5>=superness<=1, % are from visual reference definitely right beginfig(2); draw supertest 1; endfig; beginfig(3); draw supertest 0.99; endfig; beginfig(4); draw supertest 0.7; endfig; beginfig(5); draw supertest 0.51; endfig; beginfig(6); draw supertest 0.5; endfig; % Now, for <0.5, % things get problematic -- % the points in the shape generated by s=0.5 % should stay 'pointy' beginfig(7); draw supertest 0.49; endfig; beginfig(8); draw supertest 0.3; endfig; beginfig(9); draw supertest 0.01; endfig; beginfig(10); draw supertest 0; endfig; end;

Suggestions on fonts and foundries
by Tom 02 Mar '10

02 Mar '10

Some time back I recall seeing a message in which someone discussed using fonts available from foundries and recommended certain ones. Unfortunately, I can't seem to find that message. I will probably need one serif font for the text of the book, a plain sans serif font to use for entries in a table, a fancier sans serif font for chapter titles and, possibly a different not-too-plain sans serif font for page headers. Also, I can't figure out how to tell ConTeXt which font to use for page headers. Tom Benjey 717-258-9733 voice 717-243-0074 fax Twitter: @TomBenjey

[ntg-context] ppchtex questions and maybe buglets

Hi all, ppchtex is really nice. after experimenting with it i found some buglets: \starttext \setupchemical[axis=off,frame=on, option=test, size=medium, scale=medium, right=2000, left=3000, height=6000,textsize=medium]%textsize and option=test has no effect - why? \startchemical \chemical[SIX,SB135,DB246,SR6,Z,CRZ6][N,C,N,C,C,C,{\LC{\color[green]{NH}}}]%here color works \color[green]{\chemical[ADJ3,Five,SB235,DB4,Z345,SR3,CRZ3][N,C,H,H]}%color does not work here, manual says it should -why? \bottext{\offset[y=-\baselineskip]{Adenin}} \stopchemical \stoptext maybe someone can also explain how the OFF key works. the behaviour is strange in my opinion. i found nothing precise in the manual. onhttp://chneukirchen.org/blog/archive/2004/05/ppchtex.html i found following explanation: 18OFF1: do 18 small steps in direction 1 (right) but this don´t work - even with the example on the homepage. best regards Bernhard

[MkII] Difference in output in minimals versus TeX Live 2009
by Vedran Miletić 02 Mar '10

02 Mar '10

Hi, is minimals supposed to have the same output using MkII as TeX Live 2009? Or have I missunderstood what does it mean that 'MkII is frozen'? I ask because I get different results on same document. I'm using Palatino font. It seems related to spacing between letters in "il" and "ij" that is larger in current minimals. Any ideas why? -- Vedran Miletić

Dash broken in MKIV
by Andreas Schneider 01 Mar '10

01 Mar '10

Hi, in MKIV, the "long" dash (--) seems to be broken. Example: \starttext some -- text \stoptext Outputs with literal "--" instead of a longer "-" as it used to do before. It still worked ~2 weeks ago. I tested it with the minimals (beta) under Linux and Windows. Best Regards, Andreas Schneider.
