Re: [NTG-context] How to put a circle on top of a character

30 Aug 2017

      Hi Hans,

Thanks for your attention.
Indeed I understand that the stackers structures are for putting things such as a circle or a star on top of another character or constructs. 

In fact, in terms of readability, the result of your new command \interiorset{K} is better than that of \mathring{K}, but the « K » coming out with \interiorset is set in Roman, while it should be math italic (or whatever font is used in math mode).
Also the white space around it is not yet correct. I’ll test what you will have added in the next beta and then put an entry on the wiki about mathstackers.

Thanks again: OK

Hi Hans,
That’s wonderful! Indeed this is very handy and I’ll add it to the wiki.
However, before doing so, I would like to ask how is it possible to get the command act entirely in math mode, that is respecting the distances and the math fonts. Please see the attached output.
%%% begin interior-of-a-set.tex
\definemathstackers[symbol][voffset=-.30\mathexheight,hoffset=\zeropoint]
\definemathover[symbol][interiorset]["2218]
\starttext
Here is the new command \type{\interiorset{K}}: $\mathring{K} \neq \interiorset{K}$
\stoptext
%%% end interior-of-a-set.tex
I'll add an offset
\definemathstackers
 [\v!symbol]
 [\c!voffset=-.3\mathexheight,
  \c!hoffset=\zeropoint,
  \c!mathclass=ord,
  \c!topoffset=.4\mathemwidth, % poor man's italic correction
  \c!middlecommand=\mathematics]
but keep in mind, this is not really meant for accented math, more for special cases
Hans
