Delimiter matching.
The lr function allows you to match two delimiters and scale them with the
content they contain. While this also happens automatically for delimiters
that match syntactically, lr allows you to match two arbitrary delimiters
and control their size exactly. Apart from the lr function, Typst provides
a few more functions that create delimiter pairings for absolute, ceiled,
and floored values as well as norms.
Example
$ [a, b/2] $
$ lr(]sum_(x=1)^n], size: #50%) x $
$ abs((x + y) / 2) $
Function
lrElementElement functions can be customized with set and show rules.
set and show rules.Scales delimiters.
While matched delimiters scale by default, this can be used to scale unmatched delimiters and to control the delimiter scaling more precisely.
sizeSettableSettable parameters can be customized for all following uses of the function with a set rule.
set rule.The size of the brackets, relative to the height of the wrapped content.
