Hi,
In addition the the mentioned integral trickery we can now do this
\setupbodyfont[newcomputermodern-book]
\enableexperiments[math.extensibles]
\starttext
% \startformula
% x = \integral^1_2 \mathinner{\vrule height 10mm depth 10mm width
5mm} =
% x = \integral^1_2 \mathinner{\vrule height 20mm depth 20mm width
5mm} =
% x = \integral^1_2 \mathinner{\vrule height 30mm depth 30mm width
5mm} =
% x = \integral^1_2 \mathinner{x} =
% x = \integral^1_2 x
% \stopformula
% \startformula
% x = \int\Umathadapttoright^1_2 \mathinner{\vrule height 10mm depth
10mm width 5mm} =
% x = \int\Umathadapttoright^1_2 \mathinner{\vrule height 20mm depth
20mm width 5mm} =
% x = \int\Umathadapttoright^1_2 \mathinner{\vrule height 30mm depth
30mm width 5mm} =
% x = \int\Umathadapttoright^1_2 \mathinner{x} =
% x = \int\Umathadapttoright^1_2 x
% \stopformula
% $
% x = \int\Umathadapttoright^1_2 \mathinner{\vrule height 10mm depth
10mm width 5mm} =
% x = \int\Umathadapttoright^1_2 \mathinner{\vrule height 20mm depth
20mm width 5mm} =
% x = \int\Umathadapttoright^1_2 \mathinner{\vrule height 30mm depth
30mm width 5mm} =
% x = \int\Umathadapttoright^1_2 x =
% $
\def\rab{\Umathchar"1"00"007C }
\startTEXpage[offset=3cm]
$
\color[green]{\rab\Umathadapttoright^{\black 1}_{\black 2}^^3__4}
\color[blue] {\mathinner{\vrule height 30mm depth 30mm width 5mm}}
\color[red] {\rab\Umathadapttoleft ^5_6^^{\black 7}__{\black 8}}
$
\stopTEXpage
\startTEXpage[offset=10pt] % \showglyphs
$
\rab\Umathadapttoright^1_2^^3__4
\mathinner{\vrule height 30mm depth 30mm width 5mm}
\rab\Umathadapttoleft^5_6^^7__8
$
\stopTEXpage
\stoptext
So, we can have left and right sided adaptation. The
\enableexperiments[math.extensibles]
is a cheat that makes the extensible into one character (cut and paste
related).
