Is it possible to automatically "add" \left
and \right
commands in front of all brackets? The source code should be left intact, but LaTeX should interpret every pair of brackets as if they were preceded by such commands. This is because adding \left
and \right
commands is time consuming and makes source code longer and less readable. I considered defining new commands such as \lb
and \rb
for \left(
and \right)
, but it doesn't seem very elegant to me: what if I also want to add square brackets for example?
Any ideas? Thanks.

The
\DeclarePairedDelimiter
command from mathtools is useful. For example defining an absolute value macro;gives also a starred version with
\left
and\right
and the unstarred version takes an optional argument that can be
\big
,\Big
, etc
