# In minted, how to reduce the blank space between the line number and the code?

The following is example beamer file:

\documentclass[notheorems,serif,11pt]{beamer}
\usepackage{algorithm}
\usepackage{float}
\usepackage{minted}
\renewcommand{\listingscaption}{Python code}
\newminted{python}{
fontsize=\footnotesize,
escapeinside=||,
mathescape=true,
numbersep=5pt,
linenos=true,
gobble=2,
framesep=3mm}
\begin{document}

\begin{frame}[fragile]{Mesh Data Strucrure}
\begin{listing}[H]
\begin{pythoncode}
import numpy as np
point = np.array(
[(0.0, 0.0),
(1.0, 0.0),
(1.0, 1.0),
(0.0, 1.0)], dtype=np.float)
cell = np.array([
(1, 2, 0),
(3, 0, 2)], dtype=np.int)
N = point.shape[0] # the number of triangle points
NC = cell.shape[0] # the number of triangle cells
\end{pythoncode}
\caption{The basic data structure of triangle mesh.}
\end{listing}
\end{frame}

\end{document}


Finally, I get the following result in my slide:

My problem is that the blank space between the line number and code is too wide, and I want to reduce it. So how to do it? Thanks very much!

• I can't give you a clear answer without an MWE, but autogobble option seems to be of help. Jul 19 '17 at 5:24
• @CarLaTex yes, you are right. I should give more information. I have updated the question. Jul 19 '17 at 5:54
• As @yudai-nkt said, if you put autogobble instead of gobble=2 it works. (To yudai-nkt: you could post an answer). Jul 19 '17 at 5:57
• Yes, I have tested it. It works! Thanks very much! @yudai-nkt Jul 19 '17 at 5:58

The autogobble option is the way to go. Here is the excerpt from the manual:

Remove (gobble) all common leading whitespace from code. Essentially a version of gobble that automatically determines what should be removed. Good for code that originally is not indented, but is manually indented after being pasted into a LaTeX document.

By utilizing this,

\documentclass[notheorems,serif,11pt]{beamer}
\usepackage{algorithm}
\usepackage{float}
\usepackage{minted}
\renewcommand{\listingscaption}{Python code}
\newminted{python}{
fontsize=\footnotesize,
escapeinside=||,
mathescape=true,
numbersep=5pt,
linenos=true,
autogobble,
framesep=3mm}
\begin{document}

\begin{frame}[fragile]{Mesh Data Strucrure}
\begin{listing}[H]
\begin{pythoncode}
import numpy as np
point = np.array(
[(0.0, 0.0),
(1.0, 0.0),
(1.0, 1.0),
(0.0, 1.0)], dtype=np.float)
cell = np.array([
(1, 2, 0),
(3, 0, 2)], dtype=np.int)
N = point.shape[0] # the number of triangle points
NC = cell.shape[0] # the number of triangle cells
\end{pythoncode}
\caption{The basic data structure of triangle mesh.}
\end{listing}
\end{frame}
\end{document}
