OctoCounts produced this report by resolving openai/codex to commit 2f3fb111be71, 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 very large codebase by counted code lines. Code represents 91.7% of all lines, comments represent 1.7%, and the repository averages 257 code lines per file. Rust accounts for 86.7% of counted code.
