math problems in last beta (cont-en and cont-xp)
by Lutz Haseloff 24 Mar '09

24 Mar '09

Hi Hans, hi Taco, hi all, testing math with the latest ConTeXt beta i found some problems. My test file is: \usetypescriptfile[type-buy] \def\currentfontname {\ctxlua{tex.print(font.getfont(font.current()).fullname)}} \starttext \startbuffer[mathbuffer] \currentfontname $a^2 + b^2 = c^2$ $E = mc^2 \bigotimes \sum$ $α^2 + β^2 = γ^2$ \blank[big] \stopbuffer \getbuffer[mathbuffer] \usetypescript[lucida][texnansi] \setupbodyfont[lucida] \getbuffer[mathbuffer] \usetypescript[cambria] \switchtotypeface[cambria] \getbuffer[mathbuffer] \usetypescript[palatino] \switchtotypeface[palatino] \getbuffer[mathbuffer] \stoptext Latin Modern and Palatino/px work very fine. Lucida lacks greek and some operators. I found no embedded LucidaNewMath fonts in the resulting pdf. Cambria has a very ugly spacing. btw. in the wiki is described a ConTeXt command \showmathcharacters. This seems not to work anymore. The related file math-run.tex is not input at the time of format generation. Greetings Lutz P.S. will the key [texnansi] (or [ec]) remain necessary to switch to LucidaBright?

Value of Metapost variable as a label
by Curiouslearn 24 Mar '09

24 Mar '09

Hello, First of all, Mojca thanks very much for the update about TikZ. (I could not find an option to reply in Context Garden mailing list). My new question is the following. I have the following code to generate the labels for the tick marks: for i = 0 step 5 until 45: draw (i,0)*u -- (i,-0.2)*u; label.bot(decimal(i) ,(i,-0.2)*u); endfor; As you can see I use "decimal(i)" to get the labels (0,5,10,... and so on). But the font of these numbers is not the same as when I use the "btex label_text etex" command, which I have set to palatino. How can I typeset the value of Metapost variables (such as "i" in this case), using tex commands. For example, if I had to typeset (n_{1},n{2},...,n_{100}), how could I do that. On page 63 of John Hobby's metapost manual, he talks about how this could be achieved using TEX.mp. I tried typing \input TEX before \starttext, however, I get the error "I can't find file `TEX;' If I put it within the \startuseMPgraphic and \stopuseMPgraphic, it still does not work. Do I have to download this from somewhere or does Context have another solution? Thanks very much.

hangaround in right side of column?
by Jelle Huisman 23 Mar '09

23 Mar '09

Hi all, I try to get text flowing nicely around a figure but since I'm working in a columns environment \placefloat related stuff doesn't work. Using \starthangaround I get precisely what I want but I need to place figures to the right instead of to the left. I modified the definition for \starthangaround (from cont-new.tex) but I'm afraid I don't understand enough of it to get it working, anyone who can help? \starttext \def\startmyhangaround {\noindent\bgroup \dowithnextbox {\ifdim\nextboxht>\strutht\setbox\nextbox\tbox{\flushnextbox}\fi \setbox\nextbox\hbox{\flushnextbox\hskip\@@hadistance}% \getboxheight\scratchdimen\of\box\nextbox \getnoflines\scratchdimen \nextboxdp\strutdp \nextboxht\strutht \hangindent\nextboxwd \hangafter-\noflines \rlap{\flushnextbox}\ignorespaces} \hbox} \startcolumns[n=2,balance=yes] \dorecurse{2}{\input tufte \par} \startmyhangaround{\externalfigure[cow]} % figure placement is right but, \input tufte % this text needs to start left... \stophangaround \stopcolumns \stoptext Thanks, Jelle

font switching questions
by Alan Stone 23 Mar '09

23 Mar '09

Ahoi, Following a previous discussion, I've been advised to "try to avoid \switchtobodyfont and use \definedfont or \definefont instead". (1) What's the difference between \definefont and \definedfont ? (2) In the underneath example... (2a) how to implement \define(d)font for font switching ? (2b) how to define \myFontHook ? Thanks, Alan \usemodule[t-lettrine] \usetypescriptfile[tps_arial] \usetypescript[arial] \definetypeface[myFont][arial] \usetypescriptfile[tps_timesnewroman] \usetypescript[timesnewroman] \definetypeface[myOtherFont][timesnewroman] \def\myFontSize{12pt} \def\myOtherFontSize{20pt} \setupbodyfont[myFont,\myFontSize] \setuphead[chapter][style={\switchtobodyfont[myOtherFont,\myOtherFontSize]}] \starttext \chapter{Chapter One} %\lettrine[FontHook={\myFontHook}]{T}{hus}, I came to the conclusion that the designer of a new \lettrine{T}{hus}, I came to the conclusion that the designer of a new system must not only be the implementer and first large-- scale user; the designer should also write the first user manual. \stoptext

new luatex beta
by Hans Hagen 23 Mar '09

23 Mar '09

Hi, The code has been checked in for the next luatex beta. The current MKIV beta is already prepared for that (primitive initializations and changed directlua support). Also, there are a few bug fixes (esp the vf positioning) that might result in better output. There are some pending issues with math but they might as well relate to issues with the lm fonts. Anyway, we tested the beta a few days and it should work ok. One new feature in MKIV is names lua runs. In the current version we no longer have multiple lua instances (we decided that it made no sense as no data can be shared). However, in MKIV we do have a few mildly isolated instances that are defined as follows: \definenamedlua[user] [private user instance] \definenamedlua[third] [third party module instance] \definenamedlua[module] [module instance] \definenamedlua[isolated][isolated instance] the names kind of reflect what their intended usage is. By default one has no access to global data unless prefixed by global, so for instance one can access the global character data as in (untested): \startusercode tex.sprint(global.characters.data[123].description) \startusercode (there is also \usercode{...}) This prevents that users mess up with the data unintended. However, there is still read and write access so be careful. I see no advantage in a more strict model than this. Since each call to lua is reentrant, errors in your scripts will normally not result in a crash of \MKIV. The error message mentiones the second argument to the previous definitions.
