cloc

cloc ("Count Lines of Code") is a command-line utility written in Perl that counts blank lines, comment lines, and physical lines of source code across hundreds of programming languages.

Key features include:

• Broad Support: It recognizes and parses code stats for a vast array of languages, handling differences in single-line and multi-line comment styles automatically.

• Flexible Inputs: It can analyze individual source files, entire directories, specific git commits/repositories, and compressed archive formats (like .zip, .tar.gz, .deb, .rpm, or .whl files).

• Code Differences: It can compare two versions of a codebase to compute the delta in blank lines, comments, and actual code.

• Portability: Written in pure Perl with minimal external dependencies, it runs across Linux, macOS, BSD variants, and Windows (where standalone compiled .exe binaries are also available).
