Hi everyone,
With the command \definemathfence it is possible to define for instance the following command
\definemathfence[duality][angle][command=yes,factor=auto]
so that $\duality{T,\phi}$ results in $\langle T,\phi \rangle$ and the \langle and \rangle are appropriately scaled when necessary.
How can one create a command called \bracparenth in order to get a left bracket on the left and a right parenthesis on the right, that is
$\bracparenth{a,b} = [a,b)$
and so that when necessary it scales automatically.
Below is the example for \duality.
Thanks in advance: OK
%%% begin mathfence-example.tex
\definemathfence[duality][angle][command=yes,factor=auto]
\definemathfence[parenth][parenthesis][command=yes,factor=auto]
\starttext
The action of $T$ on a smooth function $\phi$ is denoted by
\startformula
\duality{T,\phi}
\stopformula
while the scalar product of two functions $f$ and $g$ is denoted $\parenth{f|g}$.
\stoptext
%%% end mathfence-example.tex

you can set left and right as : left="27E6, right="27E7
