%D \module
%D [ file=s-braille-basic,
%D version=2021.11.17,
%D title=\CONTEXT\ Style File,
%D subtitle=Playground for spacing,
%D author=Hans Hagen,

%C
%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
%D This style is triggered by the 2021 blog by Murray Sargent (from Microsoft)
%D about nemeth sequences:
%D
%D \starttyping
%D https://devblogs.microsoft.com/math-in-office/unicode-math-braille-sequences/
%D \stoptyping
%D
%D I ran into it when Mikael Sundqvist and I were working on an upgrade of the lfg
%D (goodie) files for math. Being sort of monospaces a braille font is a good
%D candidate for exploring al these math spacing parameters.
%D
%D More settings might show up and existing ones might change so it's mostly an
%D example style. Fell free to contribute. We use color so that we can see what
%D we're dealing with. Braille looks kind of interesting anyway although it was
%D never meant to be seen but felt.
%D
%D Musical timestamp: Nothing but the truth (PT with GH drum cam 5.1 bluray) ...
%D ... I'm always amazed of the power of music and wonder how that evolved with
%D and in humans.

Here is some simple inline math: \formula {$x_2 = 10 \neq \alpha$} and here is
some (quick and dirty) display:
\startformula
y = \sqrt[2]{\frac{1+x^2}{2x+x^2+4}}
\stopformula
but there are rules for that. So we need to look into those so that:
\startformula
y = \frac{1+x^2}{2x+x^2+4}
\stopformula
and
\startformula
y = \overline{2x+x^2+4} + \underline{2x+x^2+4}
% y = \overbar{2x+x^2+4}
\stopformula
come out right.

The monospaced font has no braille but actually all is kind of monospace apart
from spacing:
\starttyping
Let's show some {\bf fancy tex} code,
assuming that mono has gotten the
braille glyphs.
