problem

Existing line-counting tools often provide more functionality than necessary for simple scripts and developer tooling.

motivation

I wanted a small, dependency-light crate that could be used directly from the command line.

solution

Developed a fast and straightforward library capable of traversing directories, filtering supported files, and producing source line statistics with a minimal API.

decisions

• Designed the crate to work as a standalone CLI.
• Kept the resulted data intentionally small.
• Focused on performance and low dependency overhead.

challenges

• Correctly handling recursive directory traversal.
• Supporting common source file extensions while remaining extensible.

lessons

• A well-designed library is often simpler than its implementation.
