I am currently working on a paper in LaTex and wanted to include some source code in it. I didn’t want to use the default verbatim environment since I wanted to include syntax highlighting as well. Luckily, the listings package is an easy and extensible way to include source code inside LaTex documents. To speak first of its extensibility, here is a subset of the arguments that it can possibly take:
| Argument | Description |
|---|---|
| aboveskip | Amount of space to include above code. |
| backgroundcolor | Background color |
| basicstyle | Font-style of code (Color & Size) |
| belowskip | Amount of space to include below code. |
| breakatwhitespace | Only break at whitespace (boolean) |
| breaklines | Automatic Line Breaking (boolean) |
| commentstyle | Font-style of comments (Color & Size) |
| frame | Type of frame: l for left, r for right, t for top, b for bottom; can use combination of letters or single. |
| keywordstyle | Font-style of keywords (Color & Size) |
| language | Language of code (for highlighting purposes) |
| numbers | Where to put the numbers: none, left, or right. |
| numbersep | How far the line-numbers are from the code. |
| numberstyle | Font-style of numbers (Color & Size) |
| stringstyle | Font-style of strings in code (Color & Size) |
| tabsize | Default tab size in terms of spaces. |
| title | Show filename included in \lstinputlistings or caption. |
Here is an example of code that I used in a paper
\usepackage{color}
\usepackage{listings}
\definecolor{keyblue}{rgb}{0.1, 0.1, 0.6}
\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{stringcol}{rgb}{0.58,0.4,0.1}
\lstset{frame=l,
language=Python,
aboveskip=3mm,
belowskip=3mm,
columns=flexible,
basicstyle={\small\ttfamily},
numbers=left,
numberstyle=\tiny\color{gray},
numbersep=2mm,
keywordstyle=\color{keyblue},
commentstyle=\color{dkgreen},
stringstyle=\color{stringcol},
breaklines=true,
tabsize=4
}
\begin{lstlisting}
def greeting():
return "Hello!"
# Printing the greeting to the screen
print(greeting())
\end{lstlisting}
