math: using bold charaters for number sets

math: using bold charaters for number sets

[Paul Menzel]

[-- Attachment #1.1: Type: text/plain, Size: 562 bytes --]

Dear ConTeXt folks,


according to [1] the number sets were originally set using bold
characters and only on the blackboard the double strokes were used.

ConTeXt defines for example `\naturalnumbers` or `\reals` [2] which are
set using double strokes.

How can I redefine those to be just bold?


Thanks,

Paul


PS: Does somebody actually use these commands (`\naturalnumbers`, …`) or
do you define for example `\N`?

I've made something for an upcoming beta:

\startformula
     \reals
     {\mathbf R}
     \utfchar{"0211D}
     \utfchar{"1D411}
\stopformula

\setupmathematics
   [rendering=1]

\startformula
     \reals
     {\mathbf R}
     \utfchar{"0211D}
     \utfchar{"1D411}
\stopformula

That give the desired result. But we need to set up some rendering 
vectors so I need to discuss it with Aditya first.

And of course Aditya want as export

<m:mi>ℝ</m:mi>
<m:mi>𝐑</m:mi>
<m:mi>ℝ</m:mi>
<m:mi>𝐑</m:mi>

So that is also taken care of.

I will prefer something more verbose than rendering=1. Perhaps, 
numbersets=blackboard and numbersets=bold.

A bit tricky. Is \reals == ℝ? That is, what if I type ℝ should the 
output be bold R, or should ℝ always map to the corresponding slot in the 
unicode math font?

Sure, but I needed a quick test -)

- the export is the original (but \reals becomes ℝ)
- the rendering becomes ℝ or bold-R

you can play with the beta on the ftp server ... (math-ren.lua: we can 
consider runtime vector loading)

\setupbackend[export=yes]

\starttext

     \startTEXpage
         \startformula
             \reals {\mathbf R} \utfchar{"0211D} \utfchar{"1D411}
         \stopformula
         \setupmathematics[symbolset=blackboard-to-bold]
         \startformula
             \reals {\mathbf R} \utfchar{"0211D} \utfchar{"1D411}
         \stopformula
     \stopTEXpage

\stoptext

There is also support for:

\setupmathematics
   [symbolset={blackboard-to-bold,adityas-favourutes}]

Maybe we should start thinking of \definemathematics.

Just to close this topic. The current syntax(?)/command is the
following.

\setupmathematics
   [symbolset=blackboard-to-bold]

I prefer that ℝ is rendered as bold-R.

[…]
