protocolbuffers/protobuf has 871,834 source lines of code out of 1,127,860 total lines across 2,860 files, counted from the fa153cf32201dc5156b320591f2cd9153a7b40b8 ref at commit fa153cf32201 by the OctoCounts tokei engine on 2026-09-16. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving protocolbuffers/protobuf to commit fa153cf32201, 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.
