Font for MetaPost graphics
by Marco 10 May '12

10 May '12

The wiki claims setting up an MPenvironment is enough to change the font in MetaPost graphics: \startMPenvironment%[global] \switchtobodyfont [sans] \stopMPenvironment \starttext This should be serif. \startMPcode draw textext("This should be in sans."); \stopMPcode \stoptext However, this has no effect. All text is in default serif font. If [global] is provided, all text is in sans font. I am aware of a similar issue in a thread last year¹, but the solution didn't really address the problem. textext("\sans This should be sans.") works here, but the point is that the MPenvironment fails. Why is that? Marco [1] http://thread.gmane.org/gmane.comp.tex.context/69044

switching to a different math font (with alternatives) in the middle of document
by Mojca Miklavec 10 May '12

10 May '12

Hello, I'm just wonderding if there is a way to switch to an OpenType Math font (referred to by name or filename, without any predefined typescript) with some stylistic alternative in the middle of the document, like in the LaTeX example: running text ... \setmathfont[Scale=0.86,StylisticSet=4]{Lucida Bright Math OT} $\mathcal{ABC XYZ}$~(StylisticSet=4) ... running text ... \setmathfont{Asana Math} $\mathfrak{ABC XYZ\,abc xyz}$ or do I always need to provide a predefined typescript? How does one switch between stylistic alternatives for math? I have a problem with {\switchtobodyfont[asana] $\mathscript ABC XYZ\,abc xyz$} and I also need to figure out how to get "math bold italic sans serif greek alphabet". Any hints welcome. Thank you, Mojca

Split \startalign content on more pages

Hello, I'm a new user of context (and of this mailing list). I'm facing some problems in splitting the \startalign ... \stopalign content on more pages. This is the formulas: \setupformulas[align=right] \startformula \startalign[n=3, align={left, right, left}] \NC \text{dove} \quad \NC Y \NC = min \left({{e_{yfitest}} \over {R_{fi}}}; 0.04 \right) = min \left({{\sbc{e_yfitest}} \over {\sba{R_fi}}}; 0.04 \right) =\sbd{Y} \NR \NC \NC Z \NC = log_{10} \left({1 \over Y} \right) = log_{10} \left({1 \over \sbd{Y}} \right) = \sbc{Z} \NR \NC \NC X \NC = {{r_{fi}} \over {D_{ifi}}} = {{\sba{r_fi}} \over {\sba {D_ifi}}} = \sbd{X} \NR \NC \NC N \NC = 1.006 - {1 \over {6.2 + \left(90 \cdot Y \right)^4}} = 1.006 - {1 \over {6.2 + \left(90 \cdot \sbd{Y} \right)^4}} = \sbd{N} \NR \startluacode if X==0.06 then tex.print("\\NC \\NC \\beta_{0.06} \\NC = N \\cdot \\left(-0.3635 \\cdot Z^3 + 2.2124 \\cdot Z^2 - 3.2937 \\cdot Z + 1.8873 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.3635 \\cdot \\sbc{Z}^3 + 2.2124 \\cdot \\sbc{Z}^2 - 3.2937 \\cdot \\sbc{Z} + 1.8873 \\right) = \\sbc {beta006} \\NR") tex.print("\\NC \\NC \\beta \\NC =\\beta_{0.06}=\\sbc{beta006} \\NR") elseif X>0.06 and X<0.1 then tex.print("\\NC \\NC \\beta_{0.06} \\NC = N \\cdot \\left(-0.3635 \\cdot Z^3 + 2.2124 \\cdot Z^2 - 3.2937 \\cdot Z + 1.8873 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.3635 \\cdot \\sbc{Z}^3 + 2.2124 \\cdot \\sbc{Z}^2 - 3.2937 \\cdot \\sbc{Z} + 1.8873 \\right) = \\sbc {beta006} \\NR") tex.print("\\NC \\NC \\beta_{0.1} \\NC = N \\cdot \\left(-0.1833 \\cdot Z^3 + 1.0383 \\cdot Z^2 - 1.2943 \\cdot Z + 0.837 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.1833 \\cdot \\sbc{Z}^3 + 1.0383 \\cdot \\sbc{Z}^2 - 1.2943 \\cdot \\sbc{Z} + 0.837 \\right) = \\sbc {beta01} \\NR") tex.print("\\NC \\NC \\beta \\NC = 25 \\cdot \\left[ \\left(0.1 - X \\right) \\cdot \\beta_{0.06} + \\left(X - 0.06 \\right) \\cdot \\beta_{0.1} \\right]= \\NR") tex.print("\\NC \\NC \\NC = 25 \\cdot \\left[ \\left(0.1 - \\sbd{X} \\right) \\cdot \\sbc{beta006} + \\left(\\sbd{X} - 0.06 \\right) \\cdot \\sbc {beta01} \\right]=\\sbd{beta} \\NR") elseif X==0.1 then tex.print("\\NC \\NC \\beta_{0.1} \\NC = N \\cdot \\left(-0.1833 \\cdot Z^3 + 1.0383 \\cdot Z^2 - 1.2943 \\cdot Z + 0.837 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.1833 \\cdot \\sbc{Z}^3 + 1.0383 \\cdot \\sbc{Z}^2 - 1.2943 \\cdot \\sbc{Z} + 0.837 \\right) = \\sbc {beta01} \\NR") tex.print("\\NC \\NC \\beta \\NC =\\beta_{0.1}=\\sbc{beta01} \\NR") elseif X>0.1 and X<0.2 then tex.print("\\NC \\NC \\beta_{0.1} \\NC = N \\cdot \\left(-0.1833 \\cdot Z^3 + 1.0383 \\cdot Z^2 - 1.2943 \\cdot Z + 0.837 \\right) = \\NR") tex.print("\\NC \\NC \\NC = N \\cdot \\left(-0.1833 \\cdot \\sbc{Z}^3 + 1.0383 \\cdot \\sbc{Z}^2 - 1.2943 \\cdot \\sbc{Z} + 0.837 \\right) = \\sbc {beta01} \\NR") tex.print("\\NC \\NC \\beta_{0.2} \\NC = max \\left[ 0.95 \\cdot \\left(0.56 - 1.94 \\cdot Y - 82.5 \\cdot Y^2 \\right); 0.5 \\right] \\NR") tex.print("\\NC \\NC \\NC = max \\left[ 0.95 \\cdot \\left(0.56 - 1.94 \\cdot \\sbd{Y} - 82.5 \\cdot \\sbd{Y}^2 \\right); 0.5 \\right] = \\sbd {beta02} \\NR") tex.print("\\NC \\NC \\beta \\NC = 10 \\cdot \\left[ \\left(0.2 - X \\right) \\cdot \\beta_{0.1} + \\left(X - 0.1 \\right) \\cdot \\beta_{0.2} \\right]= \\NR") tex.print("\\NC \\NC \\NC = 10 \\cdot \\left[ \\left(0.2 - \\sbd{X} \\right) \\cdot \\sbc{beta01} + \\left(\\sbd{X} - 0.1 \\right) \\cdot \\sbc {beta02} \\right]=\\sbd{beta} \\NR") elseif X==0.2 then tex.print("\\NC \\NC \\beta_{0.2} \\NC = max \\left[ 0.95 \\cdot \\left(0.56 - 1.94 \\cdot Y - 82.5 \\cdot Y^2 \\right); 0.5 \\right] \\NR") tex.print("\\NC \\NC \\NC = max \\left[ 0.95 \\cdot \\left(0.56 - 1.94 \\cdot \\sbd{Y} - 82.5 \\cdot \\sbd{Y}^2 \\right); 0.5 \\right] = \\sbd {beta02} \\NR") tex.print("\\NC \\NC \\beta \\NC =\\beta_{0.2}=\\sbd{beta02} \\NR") end \stopluacode \stopalign \stopformula \setupformulas[align=middle] I have already tried to insert split=yes in the options of the align environment without success. I have read in "Using \startalign and friends" which is a document dated 2006 that the splitting capability of \startalign is broken. Is it still so? And by the way, is there a clever way to write a block of text under some conditions as shown in the example above other than tex.print(".....") which forces to escape every command? Thank you very much. Bye

What should the behavior be? "on \at{page}[ref]" could return "on ", but this would not be right. "\at{on page}[ref]" could return "", but otherwise "on page" would be a (colored) active link. I might try "\in{figure}[ref] \at{(page }{)}[ref]" and hope/expect "(page xx)" to be replaced by "" when referring to the current page. Maybe Wolfgang is right in suggesting writing a custom macro. I haven't looked at the code, though. Alan

\xmlinclude throws no error
by Meer, H. van der 09 May '12

Why does \xmlinclude does not throw an error when the file to be read is missing? It causes a mssing file to go unnoticed. In contrast \xmlprocessfile does throw an error, as expected. Hans van der Meer

\xmlcontext inoperative?
by Meer, H. van der 09 May '12

09 May '12

Loaded xml with: xmlinclude{problem}{include}{file} Then called up parts of its contents through a setup: \startxmlsetups xam:define:get % The definition is the one with content. \xmldoiftext{#1}{.}{ \foundtrue \xmlflush{#1} \xmlcontext{#1}{.} } \stopxmlsetups The strange thing is that the \xmlflush typesets verbatim the contents of the node called up: <math version="2.0" xmlns="http://www.w3c.org/mathml"> <apply> <eq/> <ci> f(x) </ci> <apply> <plus/> <ci> 1 </ci> <apply> <power/> <ci> x </ci> <ci> 4 </ci> </apply> <apply> <power/> <ci> x </ci> <ci> 7 </ci> </apply> </apply> </apply> </math> but, to my surprise the \xmlcontext{#1}{.} lets it disappear completely. So does \xmlflushcontext{#1}. In other parts of the program \xmlcontext does what it should do, thus the mkvi format seems ok. What could have happened? Some detrimental effect of the \xmlinclude?

Though this command works perfectly and is nicely adaptable, in the end it does not give me what I would have liked. Perhaps my description of what I want was not clear enough. For me, both commands, \somewhere{}{}[ref] and \atpage[ref], have in common that they are imprecise when I want precision, namely when the float is not at the same page as its reference, and precise when they are in fact redundant, that is, when float and reference are on the same page, where the reader will see it at one glance, whether it is above or below. Writing, for instance, on page 20: "See example 2 on page 20" is not wrong but somehow it looks clumsy and unprofessional to me, and unworthy of ConTeXt, if I may say so. The challenge would seem "to pick ConTeXt's brain" just before the final processing run, when it knows whether float and reference will be on the same page or not. Could this perhaps be solvable by some Lua-code? Anyway, for lack of a better solution, I will for the time being refer to each float with "\in{ex.}[ref] on \at{page}[ref] \somewhere{on the previous page}{on the next page}[ref] \somewhere{above}{below}[ref]" and manually comment out, after the final processing run, what I cannot use. Not very elegant, to put it mildly, and I hope that someone on this list has a better solution. Kind regards, Robert Blackstone
