Using Ralph Smith's Formal Script font

Using Ralph Smith's Formal Script font

[Aditya Mahajan]

How do I use Ralph Smith's formal script font [1] within context. I 
want to define a command like \mathrsfs{A} that will use A in this 
font.

Thanks

There might be a cleaner way, but here's an example that works here
(switches to rsfs outside math mode):

\def\mathrsfs#1{\text{\definedfont[RalfSmithFormalScript]#1}}
$\mathrsfs{A}$

(You can use "\definedfont[rsfs10] A" outside math mode.)

one can make symbols (see symb-*.tex), which is probably the best way to go here; otherwise peek into math-*.tex files to see how math symbols can be defined. (the tricky part is that normally math script fonts have more chars so overloading one by a RS fotn may give problems)

This is an old mail. I could not figure out how to do this properly in 
CONTEXT. The closest that I managed was using scrload.tex from rsfs 
bundle, which uses

%%------- scrload.tex----------------------------
\font\tenscr=rsfs10 % scaled \magstep1
\font\sevenscr=rsfs7 % scaled \magstep1
\font\fivescr=rsfs5 % scaled \magstep1
\skewchar\tenscr='177 \skewchar\sevenscr='177 \skewchar\fivescr='177
\newfam\scrfam \textfont\scrfam=\tenscr \scriptfont\scrfam=\sevenscr
\scriptscriptfont\scrfam=\fivescr
\def\scr{\fam\scrfam}
%% ------------------------------------------

using this definition I get a command \scr which is same as \cal but 
uses ralph smith formal script font. The trouble is that the fonts are 
not scaled to document font size.

Mojca's suggestion of using
\def\mathrsfs#1{\text{\definedfont[RalfSmithFormalScript]#1}}

and using $\mathrsfs{A}$ works, but does not give correct spacing for
superscipts. Compare $\mathrsfs{A}^T$ with ${\scr A}^T.


What is the context way of doing the same as scrload.tex. Looking at 
math-*.tex and font-ini.tex, I tried

%-----------------------------------
\def\scr{\mathortext{\fam\purefamily{ralphscript}}{\symbolicfont{RalphScript}}}

\definefontsynonym [RalphScript][Serif]

\def\ralphscript#1{\mathortext\domathtext\donothing{\scr #1}}

\definefamilysynonym [default] [ralphscript] [rsfs]
%------------------------------------------------

I do not understand this, and no wonder this does not work. What am I 
missing.

Thank you. I will play around with magstep to get the scaling right to 
the document font size.

since it's an italic script, maybe adding an italic correction in the 
definition  is enough:

\def\mathrsfs#1{\text{\definedfont[RalfSmithFormalScript]#1\/}}

and using $\mathrsfs{A}$ works, but does not give correct spacing for
superscipts. Compare $\mathrsfs{A}^T$

Thanks, this works perfectly.

Now, I need to worry about getting dsfont working :)
