loc

loc is a tool for counting the lines of code in a programming project. It is written in C++ and designed to be very fast.

Suported languages

loc supports the following languages:

• C
• C++
• C#
• Python

Any C-style language should work, and the program uses the C line counter for any file extension not recognized.

Usage

loc [options] pattern path1 path2 ...

Options

-h [ --help ] - Display help

-j [ --jobs ] - Number of threads to use. Default is number of CPU cores available

-i [ --ignore ] - Semicolon-separated list of directories and files to ignore

pattern - Semicolon-separated list of file extensions to search for

path - Path to file or directory to search

Example

To count the lines of code in the loc codebase from the toplevel directory, ignoring the include directory and the loc.cpp file, and running on 10 threads, use this command:

loc -j 10 --ignore "loc/include;loc/loc.cpp" ".cpp;.h" ./loc

Speed

loc is designed to be as fast as possible using multi-threading.

Counting the total lines of code in the Boost C++ libraries (over 4 million lines of code) takes about 5.1 seconds.
