gitignore.nix

Reads multiple gitignore sources including parent, user, and subdirectory rules, closely mimicking git behavior without requiring team-wide changes, as highlighted in the features list.

Ensures source hashes only change with output modifications, providing deterministic Nix builds, which is a key advantage over alternatives like fetchGit per the comparison table.

Avoids descending into ignored directories, improving evaluation speed on large repositories with many ignored files, as noted in the performance benefits section.

Evaluates purely without import-from-derivation, making it compatible with restricted evaluation modes like Hydra, a strength emphasized in the features and comparison.
