multiple breaklines symbols for minted

Question

I would like to allow minted to break lines after either ., , or a space. Currently I could only break lines either after , or before . How can I allow more characters?

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{minted}
\usepackage{upquote}
\setminted{fontsize=\small, breaklines=true, breakbefore=., breakafter={,}, 
breakbytokenanywhere=true, frame=single, numbers=left, numbersep=5pt, fontfamily=tt}
\begin{document}
\begin{minted}{python}
results = pd.DataFrame(data=results,columns=['Clusters C','Intertia']).set_index('Clusters')
\end{minted}
\end{document}

Answer 1

You can use breakafter={<char 1><char 2>...}, and use \space to represent , as mentioned under option breakafter in documentation of package fvextra. Note that breakafter option is defined in fvextra and inherited by minted.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{minted}
\usepackage{upquote}
\setminted{
  fontsize=\small, 
  breaklines=true, 
  breakafter={.,\space}, 
  breakbytokenanywhere=true, 
  frame=single, 
  numbers=left, 
  numbersep=5pt, 
  highlightcolor={red!20}, 
  fontfamily=tt
}

\begin{document}
\begin{minted}{python}
# break after .
results = pd.DataFrame(data=results,columns=['Clusters C','Intertia']).set_index('Clusters')
# break after ,
results = pd.DataFrame(data=results,columns=['Clusters C','Intertia','Extra col']).set_index('Clusters')
# break after \space
result_a result_b result_c result_d result_e result_f result_g result_h result_i = some_tuple
\end{minted}
\end{document}
