nlohmann/json has 40,672 source lines of code out of 63,626 total lines across 94 files, counted from the 7b2d73cf2e443adbe7903754f912ed95b42504f1 ref at commit 7b2d73cf2e44 by the OctoCounts tokei engine on 2026-09-08. 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 nlohmann/json to commit 7b2d73cf2e44, 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.
