Developer Measures ULOC Uniqueness Across Languages
The author evaluated scc's Unique Lines of Code (ULOC) metric across 3,418 top GitHub repositories by language, using a Python script with shallow git clones to build a 472 MB SQLite database containing 2,703,656 file records and about 410,529,727 code lines. Initial analysis showed wide language variance in uniqueness—Shell about 76% highest and Lua about 39% lowest—while per-repository averaging reduced monorepo and size biases.
Key Points
- 1Processed 3,418 repositories yielding 2,703,656 file records and 410,529,727 code lines.
- 2Revealed language uniqueness variation: Shell ~76% unique, Go ~55.8%, Lua ~39.2%.
- 3Suggests idioms and boilerplate distort complexity metrics; per-repo averaging reduces monorepo and size biases.
Scoring Rationale
Provides useful cross-language empirical analysis; limited by single-author methodology, top-repo sampling, and potential monorepo biases.
