I was wondering whether I could use the labeling mechanism explained here to get the line numbers that I want to use for highlighting code via highlightlines
in minted.
I am imagining something like this (Modified example from https://tex.stackexchange.com/a/483714/85983):
\begin{minted}[linenos=true, escapeinside=!!, highlightlines=\ref{myline}]{c++}
i = i + 1 ;
j = j + 1 ; !\label{myline}!
k = k + 1 ;
\end{minted}
The important line is line \ref{myline}.
In the resulting output the line j = j + 1 ;
should be highlighted.
