Introduction - Calculate 'Actual' Lines Of Code

Python script: useful utility to calculate lines of code for all major languages (java, ruby, objective-c, python, javascript)

Objective:

Anyone who writes code wants to have less lines to meet the objective of the program. This utility script helps to identifying real lines of code and prints to console:

• type of file and language
• comments (single and multi-line)
• empty / blank lines
• actual lines of code
• total LOC; for each file in the directory.

Usage:

• on MacOS / Linux, simply copy the executable in the code root direcotry and execute it (double click).
• on Windows, copy the .py file in the code root directory and execute it via command prompt. (Pre-req - python.exe to be installed. More details --> https://docs.python.org/3/faq/windows.html)

Supports Python version 2 and 3

Sample Console Output

(This output is when executed from a directory having .py and .java file)
