cargo-countlines

Quickly and easily count lines of code in any file or directory

cargo-countlines is a simple command-line tool that allows you to count lines of code in any file or by recursively traversing any directory.

• Count SLOC in all major programming languages
• Count code, comments, and blank lines separately
• Define your own languages by providing a JSON file
• Choose between single-threaded, async, or parallel counting for maximum performance
• Exclude any directories or files using unix glob syntax
• Optional progress information while counting
• Option to follow symbolic links
• Option to restrict the maximum recursion depth
• Option to produce machine-readable output

Examples

Count SLOC in this crate, excluding the target/ directory.

$ cargo countlines --exclude "target" .

Count SLOC single-threaded, following symbolic links, recursing to a depth of 3, excluding python and ruby files in an arbitrary directory and produce machine-readable output.

$ cargo countlines -m sync --follow-links -e "*.py" -e "*.rb" -d 3 --machine-readable /home/me/my_dir
