middle edit

wanted:

Failed to parse (unknown function "\middle"): {\displaystyle \left\{x \in A \middle| x > 0\right\}}

what currently works:

 
However the middle delimiter does not grow with the arguments. This is wanted in some cases, i.e. see https://tex.stackexchange.com/questions/108388/how-to-automatically-scale-mid-within-delimiters?noredirect=1

A workaround is to use the \Bigg etc

 
\Biggl\{ 
f \in \mathcal C^\infty(\mathbb R^n) 
\Bigg| 
\forall \alpha, \beta \in \mathbb N_0^n: \left\| x^\alpha \frac{\partial^\beta}{\partial x^\beta} f \right\|_\infty < \infty 
\Biggr\}

Longrightarrow edit

Workaround

 
0\, \xrightarrow{f}\, A\, \xrightarrow{\ g\ }\, B\, \xrightarrow{\;\;h\;\;}\, C\, \xrightarrow{\quad i\quad}\, D\, \xrightarrow{\quad}\, 0
