Hi, There is a question on TeX.SX asking how to change the font of \sin, \cos, etc. http://tex.stackexchange.com/q/243893/323 I looked at the code, and there does not appear to be an easy solution. The \mathfunctionlabeltext command has \mathupright hard coded. One option is to keep this configurable using \setupmathematics, perhaps mfunction=(normal|italic|sans). In any case, I think that the current implementation is a bug. The default font for mathfunctionlabeltext should be typeset in the bodyfont. Aditya

oh, is that ever needed? italic sin?

Are you sure? In many cases the math font is different from the bodyfont.

MkII used the math font too for \sin etc. but you where able to change it with the “text” key from \definetypeface. % engine=pdftex \definetypeface [mathfunction] [rm] [serif] [modern] [default] \definetypeface [mathfunction] [ss] [sans] [modern] [default] \definetypeface [mathfunction] [mm] [math] [palatino] [default] [text=ss] \setupbodyfont[mathfunction] \starttext $sin \sin$ \stoptext Wolfgang

The bold and italic symbols/letters aren’t a problem because the have their own unicode points but for the normal upright characters there should be proper key (like the lcgreek and ucgreek keys) which prevent ConTeXt to make them into italic characters.

Hi Hans, Thanks for the new feature in \setupmathematics. I did some testing of the feature on a several documents, , and followed the discussions you had with Aditya and Wolfgang. Everything works fine, except that when one tries to modify, for instance the definition of \liminf (in order to have it as an underlined lim), ConTeXt reports an error. Please see below the minimal example and the error message. In the minimal example if you uncomment the lines modifying the definition of \liminf on gets an error message. %%%% begin test-functionstyle.tex \setupmathematics [functionstyle=\ss, functioncolor=red] %\unprotect %\definemathcommand [liminf] [limop] {\underline\mfunctionlabeltext{lim}} %\protect \starttext \startformula f = \sin i\omega x^{\sin(x^{\sin(y)})} \stopformula Fatou's lemma implies \startformula \int_{\Omega}\liminf_{n\to\infty} (1+\cos(n|x|))dx \leq \liminf_{n\to\infty}\int_{\Omega}(1+\cos(n|x|))dx. \stopformula \stoptext %%%% end test-functionstyle.tex The error message is: \begingroup \mfunctionlabeltext #1->\begingroup \math_tags_mfunctionlab {#1}\c_apply_fun... \483>limop #1->\mathop {#1 } l.45 \int_{\Omega}\liminf _{n\to\infty} (1+\cos(n|x|))dx \leq \liminf_{n\to\inf...

Hi Aditya, Thanks for your remark: indeed with the correct use of \underline, I get what was intended, but somehow before yesterday ConTeXt was more tolerant and for years it accepted my wrong definition of \liminf… However, with the new features of \setupmathematics, the underlined word lim has two colors: for instance with the option \setupmathematics [functioncolor=red] the word lim is in red, but the underline is in black. If I understand correctly, the option \setupmathematics [functionstyle=\normalrm, functioncolor=red] uses the normal roman font in math mode, that is math italic if for instance one is using LM roman as text font. Am I right? A final question: assuming one needs somewhere a command named weak limit, that is \weaklim, I tried the following definition: \definemathcommand [weaklim] [limop] {\mfunctionlabeltext{weaklim}} but I don’t get the word weaklim printed: what am I doing wrong? Here is the example: % begin weaklim.tex \definemathcommand [weaklim] [limop] {\mfunctionlabeltext{weaklim}} \starttext If $\phi_{n}(x) := \sin(n|x|)$, then $\weaklim_{n\to\infty}\phi_{n} = 0$. \stoptext % end weaklim.tex Best regards: OK

Everything works fine, except that when one tries to modify, for instance the definition of \liminf (in order to have it as an underlined lim), ConTeXt reports an error.

...
%\definemathcommand [liminf] [limop] {\underline\mfunctionlabeltext{lim}}

\underline{....} takes an argument.

Hi Aditya,

Thanks for your remark: indeed with the correct use of \underline, I get what was intended, but somehow before yesterday ConTeXt was more tolerant and for years it accepted my wrong definition of \liminf… However, with the new features of \setupmathematics, the underlined word lim has two colors: for instance with the option \setupmathematics [functioncolor=red] the word lim is in red, but the underline is in black.

you can set lots of colors so formulas can be real colorful

...

If I understand correctly, the option \setupmathematics [functionstyle=\normalrm, functioncolor=red] uses the normal roman font in math mode, that is math italic if for instance one is using LM roman as text font. Am I right?

functionstyle=<somedefinedtextstylealternative> will box the stuff and uses the given fon, otherwise it will use whatever is set and when nothing is set it will use mathupright (cf aditya's wish and previous behaviour)

...

A final question: assuming one needs somewhere a command named weak limit, that is \weaklim, I tried the following definition: \definemathcommand [weaklim] [limop] {\mfunctionlabeltext{weaklim}} but I don’t get the word weaklim printed: what am I doing wrong? Here is the example:

If $\phi_{n}(x) := \sin(n|x|)$, then $\weaklim_{n\to\infty}\phi_{n} = 0$.

\stoptext % end weaklim.tex

it helps to define the label \setupmathlabeltext[en][weaklim=wlim] ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Thanks Hans! Out of curiosity I tried textcolor and textstyle as in \setupmathematics [functionstyle=, functioncolor=darkred, textstyle=bold, textcolor=blue] and discovered that these two work also… By the end of the week I’ll wikify these. Thanks and best regards: OK
