I am using minted to show source code in my document like this:

section{Image functions}

inputminted{python}{src/imagefuncs.py}



section{Matrix operations}

inputminted{python}{src/matrices.py}



section{Block operations}

inputminted{python}{src/blocks.py}

and so on for several files. Is there a way to count the number of lines in these files and output a total.

Python pseudo code:

paths = ['src.py', 'matrices.py', 'blocks.py']

total = 0

for path in paths:

    total += linecount(path)

print(str(total))

Any similar questions I found were for listings and only one file.

Edit: To be clear, I want to do this in latex, the python code is to illustrate.

The following code will print the code listing and a line count (global). Please note that this is definitely not the most efficient approach.

You can add a key, which I call addlines to the inputminted commands you want the total number of lines is taken care of.

begin{filecontents*}{test1.py}

paths = ['src.py', 'matrices.py', 'blocks.py']

total = 0

for path in paths:

    total += linecount(path)

print(str(total))

end{filecontents*}



begin{filecontents*}{test2.py}

paths = ['src.py', 'matrices.py', 'blocks.py']

total = 0

end{filecontents*}
