OctoCounts produced this report by resolving donnemartin/system-design-primer to commit b02784ffeb28, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
This is a small codebase by counted code lines. Code represents 8.5% of all lines, comments represent 61.6%, and the repository averages 21 code lines per file. Python accounts for 64.2% of counted code.
