Locoti

Locoti is a fork of Locot. A simple utility for tracking lines of code over time in a Git repository. Outputs CSV for visualization and analysis.

Improvements over Locot

• Reads commit trees directly from the local Git object database instead of cloning and checking out every revision.
• Caches subtree stats by Git tree ID, so identical trees across history are counted once
• Caches blob-level parsing and ignore decisions to reduce repeated work during history scans
• Uses faster hash maps (rustc_hash::FxHashMap) in the hot path
• Improves ignore filtering by respecting .gitignore and .ignore rules
• Improves language detection for extensionless files via shebang detection
