I agree about \rm. However, _{\tf blah} once (in MkII) selected the text font. e.g. \starttext \placeformula\startformula M_{\tf Sun} \stopformula \stoptext Is the II->IV change in \tf semantics intended? It's not hard to adjust for by using 'sed'. I raise the issue only in case the change is not intended. Actually, the example just as above (i.e. using modern fonts) works fine works in MkII and MkIV. It also works if "\setupbodyfont[palatino]" is inserted as the first line. It's fails only when using Palatino with Euler (at least, in the way that I did it). That data doesn't say what the right behavior is. But it may help you decide. -Sanjoy ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

Agreed. The wiki page for "Project Structure" has always shown setups (via \project ... ) going after the \startcomponent or \startproduct. I've edited the examples to have setups before the \start(product|component). If I did it wrong, let me know. -Sanjoy ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

I would like to test and hopefully use this setup for _Street-Fighting Science and Engineering_. It should also give the setup a thorough workout. But I can't quite get the preamble right. The test file below typesets text and math in palatino. \usetypescriptfile[euler-with-pagella] \definebodyfontenvironment[10.5pt] \setupbodyfont[palatino,10.5pt] \starttext \input knuth \placeformula\startformula a^2 + b^2 = c^2. \stopformula \stoptext If I add \appendtoks \rm \to \everymathematics \setupmathematics[lcgreek=normal, ucgreek=normal] just before \starttext, the math is typeset in roman pagella. What am I doing silly? Also, one of my reservations about using Euler for math, which readers complained about in _Street-Fighting Mathematics_, is that v and \nu (kinematic viscosity) look so similar.
