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

2017-08-30 Thread Otared Kavian

Hi Hans,

Regarding what you have added on line 1327 of math-stc.mkvi, that line should be

\definemathover[\v!symbol][interiorset]["2218]

(instead of "2217).

I added also a wiki page for mathstackers:

http://wiki.contextgarden.net/mathstackers

Best regards: OK

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

2017-08-30 Thread Otared Kavian

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,

However, before doing so, I would like to ask how is it possible to get the

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

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

The proper solution in LaTeX is to use the \mathring accent (I think that 
amssym package defines that). The accent should also be available in 
ConTeXt (sorry cannot check right now, but a simple grep of char-def.lua 
should confirm that).
