Hi there,

Am used to seeing the names of well known functions in upright math font, instead of italics. With LaTeX, it seems, this is default, plus one can use macros like `\mathrm` or `\textrm` for other text. An `\hbox{}` too, in plain TeX, but not around `\sin`, for example.

With ConTeXt's LuaTeX-Plain format (may ConTeXt itself as well), these functions are in italics. Is it possible to control this via the redefinition of the math fonts? Following does not work for me:

\font\lmromr = {LucidaBrightMathOT:mode=base} at 14pt \font\lmromi = {LucidaBrightMathOT:mode=base} at 14pt \font\lmromsr = {LucidaBrightMathOT:mode=base;script=math;ssty=0} at 12pt \font\lmromsi = {LucidaBrightMathOT:mode=base;script=math;ssty=0} at 12pt \font\lmromssr = {LucidaBrightMathOT:mode=base;script=math;ssty=1} at 10pt \font\lmromssi = {LucidaBrightMathOT:mode=base;script=math;ssty=1} at 10pt

\textfont0 = \lmromr %--sin, cos, numbers \scriptfont0 = \lmromsr % \scriptscriptfont0 = \lmromssr % \textfont1 = \lmromi %--variables \scriptfont1 = \lmromsi % \scriptscriptfont1 = \lmromssi % \textfont2 = \lmromr %--symbols \scriptfont2 = \lmromsr % \scriptscriptfont2 = \lmromssr % \textfont3 = \lmromr %--extras \scriptfont3 = \lmromsr % \scriptscriptfont3 = \lmromssr %

It's more like this: \font\tenrm=file:lucidabrightot.otf:+liga;+kern;+tlig;+trep at 10pt \font\sevenrm=file:lucidabrightot.otf:+liga;+kern;+tlig;+trep at 7pt \font\fiverm=file:lucidabrightot.otf:+liga;+kern;+tlig;+trep at 5pt \font\tentt=file:lucidabrightot.otf at 10pt \font\tenit=file:lucidabrightot.otf:+liga;+kern;+tlig;+trep at 10pt \font\tenit=file:lucidabrightot-italic.otf:+liga;+kern;+tlig;+trep at 10pt \font\tenbf=file:lucidabrightot-demi.otf:+liga;+kern;+tlig;+trep at 10pt \font\tenbi=file:lucidabrightot-demiitalic.otf:+liga;+kern;+tlig;+trep at 10pt \font\mathfonttextupright=file:lucidabrightmathot.otf:ssty=0;fixmath=yes at 10pt \font\mathfontscriptupright=file:lucidabrightmathot.otf:ssty=1;fixmath=yes at 7pt \font\mathfontscriptscriptupright=file:lucidabrightmathot.otf:ssty=2;fixmath=yes at 5pt \textfont0=\mathfonttextupright \scriptfont0=\mathfontscriptupright \scriptscriptfont0=\mathfontscriptscriptupright \tenrm

Same for CambriaMath or LatinModernRomanMath. For `\<font>0`, tried a non-math font, but it did not work. How to set `\<font>0` to use roman? and `\<font>1` to use italics?

You really need to keep in mind that plain tex is an example tex format, used for the books that DEK makes and that it normally expects additional definitions. it's fine to extend it, e.g. with different font support, which in 8 bit fonts is quite some work due to differences in encoding, but you must ask yourself if you want to write all that code. The plain support code that ships with context is mostly meant for testing. Anyway, I've added lucidaot to plain-math.tex and as a convenience added a --lucidabright switch, so: mtxrun --script plain --lucidabright somefile.tex instead you can use \lucidabright in a document (but then \latinmodern gets preloaded too). A more efficient setup is possible but not on the agenda (as we have context already).
