apple/darwin-xnu has 1,106,636 source lines of code out of 1,670,222 total lines across 3,134 files, counted with tokei from the a449c6a3b8014d9406c2ddbdc81795da24aa7443 ref at commit a449c6a3b801 on November 2, 2026. Tests, docs and generated files are excluded under OctoCounts' canonical public options.

OctoCounts produced this report by resolving apple/darwin-xnu to commit a449c6a3b801, downloading the repository source archive, and counting files selected by the effective rules 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; an exact reproduction needs the same commit, engine version, and effective counting rules.

## Counting rules and retention

apple/darwin-xnu: tokei-15.0.0, policy directories-v1; docs excluded, tests excluded, generated excluded. Excluded directory names: .cache, .generated, .git, .next, __tests__, build, dist, doc, docs, documentation, fixtures, gen, generated, node_modules, target, test, tests, vendor. Ignored languages: none. Repository declarations: off. Exclusions are rule-based; they do not prove that every test, document or generated file was removed.

Saved reports remain subject to cache cleanup and replacement. Export the JSON or text for durable citation; live repository URLs can change.
