latest beta (again)
by Thomas A. Schmitz 09 Oct '08

09 Oct '08

Hans, I still have some problems with my fonts in the latest beta. Maybe it has to do with the latest optimizations. I'm just wondering: in my Greek typescripts, I define several fontfeatures and connect them with featurefiles, like so (just an example, the list is longer): \installfontfeature[otf][gent] \installfontfeature[otf][kori] \definefontfeature [korinthia] [mode = node ,language = dflt ,script =latn,kern=yes,tlig=no,trep=no,kori=yes,featurefile=korinthia.fea] \definefontfeature [gentiumgreek] [mode=node,language=dflt,script=latn,kern=yes,tlig=no,trep=no, gent=yes,featurefile=gentium.fea] \starttypescript [serif] [GreekGentiumAlt] [name] \definefontsynonym [Serif] [name:GenAR102] [features=gentiumgreek] \definefontsynonym [SerifItalic] [name:GenAI102] [features=gentiumgreek] \definefontsynonym [SerifBold] [Serif] \definefontsynonym [SerifBoldItalic] [SerifItalic] \stoptypescript \starttypescript [serif] [GreekKorinthia] [name] \definefontsynonym [Serif] [name:Korinthia] [features=korinthia] \definefontsynonym [SerifItalic] [Serif] \definefontsynonym [SerifBold] [Serif] \definefontsynonym [SerifBoldItalic] [Serif] \stoptypescript The main font definition is of this form: \starttypescript[greek] \definetypeface[greek][rm][serif][\currentmoduleparameter{font}] [default][rscale=\currentmoduleparameter{scale}] \stoptypescript \usetypescript[greek] So I'm just wondering: must the "features=" be included into the \definetypeface as well? I have the impression that the different features I define are not used at all... Thomas

"Math drawings for dummies"
by Mojca Miklavec 09 Oct '08

09 Oct '08

Hello, for those who are afraid of Metapost (or simply think that it takes too much time to program a simple figure with not too fancy features), there's a magnificent point-and-click tool for creating mathematical drawings with "perfect precision" and TeX labels matching the style of your document. (If you want to find itersection of curves, or curves going through several points, you don't need to "pretend that you have hit the intersection" as you would do in Corel Draw.) The prerelease version has TikZ export (with plain/LaTeX/ConTeXt support included). http://www.geogebra.org -> future Mojca

new beta
by Hans Hagen 08 Oct '08

08 Oct '08

Hi, the new beta has some optimizations wirh regards to the font memory footprint (at the cost of convenience but that only concerns me) Hans for chinese users: there is not much more memory to gain (unless we accept more mess) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

The file 'core-job.tex' should do this but it is itself not included. Is 'core-job.tex' not needed? 'cont-sys.tex' has a commented entry \runMPgraphicstrue uncommenting this works. There is also a variable \runMPTEXgraphicstrue. What is this for? Should this be uncommented, too? Will this be overwritten with the next update? Wolfgang

How to obtain blackboard bold?
by Marcin Borkowski 08 Oct '08

As in subject;) I found out that {\mb R} gives me the symbol for the real line; is it _the_ ConTeXt way or should I do it in another way? Greets -- Marcin Borkowski (http://mbork.pl) Kim jest ta, co wyłania się z pustyni, Idzie wsparta na swoim Oblubieńcu?

how to typeset this formula ?
by Steffen Wolfrum 08 Oct '08

08 Oct '08

Hi, I have a DOC-file with a lot of quite complex math formulae. Trying to find a good workflow from doc to context I was experimenting with the Word plugin MathType, resp. with the different translator options (any better tip very welcome!). The best results I had with typesetting the code with newmath. Only one kind of formula with arrays gave errors. I attach the respective formula as a doc file here. Does anybody know a better way to deal with this kind of formulae in ConTeXt? Any help very much appreciated!! Steffen

misbehaving \column
by Mojca Miklavec 08 Oct '08

08 Oct '08

Hello, The \column command does not want to obey me ... The text following \column simply jumps to the next page. This time I cannot think of any workaround :( Well, in the worst case I can still insert a table. \starttext \section{first} \dorecurse{80}{dummy } \startcolumns \externalfigure[dummy][width=\textwidth] \input tufte \column \input tufte \stopcolumns \input tufte \stoptext Thanks a lot, Mojca

more bad news about latest beta
by Thomas A. Schmitz 08 Oct '08

08 Oct '08

OK, I have more bad (for me) news about the latest beta: it simply refuses to play with some of my fonts; most importantly for me with the Gentium fonts. Whenever I try to compile something with Gentium in it, I get the error message !luaTeX error (file /Users/tas/Library/Fonts/GenAR102.ttf): Invalid glyph index (gid 1699) ==> Fatal error occurred, no output PDF file produced! MtxRun | fatal error, code: 70 I have now compared the latest beta and an older one, and I think the culprit is this line: load otf | featurefile: /Users/tas/texmf/fonts/fea/context/greek- babel.fea luatex then goes on to create luatex-cache/context/408a90c432ceda2c1e4a80ad5d0e5350/fonts/otf/GenAR102(a)greek-babel.tma luatex-cache/context/408a90c432ceda2c1e4a80ad5d0e5350/fonts/otf/GenAR102(a)greek-babel.tmc The thing is, I know that Gentium doesn't work with this fea file; that's why I wrote one specifically for this font. Gentium is nowhere connected to this fea file. When I use an older version, this fea file is not used and GenAR102(a)greek-babel.tma is not created. The newer version creates it, and I have no clue why... Very puzzled Thomas

Even an explizit {\switchtobodyfont[8pt] \startuseMPgraphic <mp-code> \stopuseMPgraphic } didn't work. I will use one of the other solutions. Thank you very much! Wolfgang

latest beta
by Thomas A. Schmitz 08 Oct '08

08 Oct '08

Hi Hans, the latest beta has a problem with font handling: in my Greek output, the letters "sigma" and "sigmaalt" don't work anymore; they're replaced either by some "undefined" character (box with letter "X" in it) or by empty spaces. I tried to find out where something has changed, but haven't found anything so far. If you don't have an immediate idea what's wrong, I'll try to investigate further. Thomas
