📚 1. Packages

1.1. Packages for Code: minted

• import package minted for code highlighting.

\usepackage{minted}

• Before using minted, you should have python version>2.7 and install pygments first.

python -V

pip install pygments

• It may be show error message

You must invoke LaTeX with the -shell-escape flag`. 

• The reason is that the minted package needs to call the pygments package to highlight the code, and the pygments package needs to call the system command. The -shell-escape parameter is used to allow the minted package to call the system command.
• It’s necessary to add -shell-escape parameter to the setting file, the following json file is a part of it.

"latex-workshop.latex.tools": [
        {
            "name": "xelatex",
            "command": "xelatex",
            "args": [
                "--shell-escape",
                "-synctex=1",
                "-interaction=nonstopmode",
                "-file-line-error",
                "%DOCFILE%"
            ]
        },
        {
            "name": "pdflatex",
            "command": "pdflatex",
            "args": [
                "--shell-escape",
                "-synctex=1",
                "-interaction=nonstopmode",
                "-file-line-error",
                "%DOCFILE%"
            ]
        },
        {
            "name": "latexmk",
            "command": "latexmk",
            "args": [
                "--shell-escape",
                "-synctex=1",
                "-interaction=nonstopmode",
                "-file-line-error",
                "-pdf",
                "-outdir=%OUTDIR%",
                "%DOCFILE%"
            ]
        },
        {
            "name": "bibtex",
            "command": "bibtex",
            "args": [
                "%DOCFILE%"
            ]
        }
    ],

• Then it may also show error message

You must have `pygmentize' installed to use this package.

• This is because you installed pygments failed or the pygments package is not in the system path. In windows 10 or later versions, there is a inside python version in Disk C.

• You will find pygmentize.exe in path: C:\Users\username\AppData\Local\Programs\Python\Python37\Scripts, add the path to the system path, then it will work.

• Example for minted package

\begin{minted}[linenos=true,frame=lines,framesep=2mm]{python}
def quick_sort(arr):
    if len(arr) < 2:
        return arr
    else:
        pivot = arr[0]
        less = [i for i in arr[1:] if i <= pivot]
        greater = [i for i in arr[1:] if i > pivot]
        return quick_sort(less) + [pivot] + quick_sort(greater)
\end{minted}
