espressif/esp-idf has 2,887,893 source lines of code out of 5,141,258 total lines across 16,066 files, counted from the 85c826ecb1d07e3d238ed506e9f560507b1a4b0e ref at commit 85c826ecb1d0 by the OctoCounts tokei engine on 2026-09-06. 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 espressif/esp-idf to commit 85c826ecb1d0, 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.
