I want to produce MATLAB prettified code with MATLAB code highlighted with tikz background. The environment itself works. Using .\ causes error. alsoletter={.\\} in \lstdefinestyle does not seem to work

\newcommand{\matlabline}[1]{#1}will fail. You can not use verbatim like material as argument. The code then can no longer adapt the catcodes.tcblistingenvironment from the tcolorbox package.
