liboxen 0.53.0

Oxen is a fast data version control system, built with machine learning training data in mind. Designed to handle terabytes of data with ease, using a workflow similar to git. Version both structured and unstructured data of any modality: text, images, video, audio, CSV, Parquet, JSONL, model checkpoints, and more. liboxen is the embeddable core library behind the oxen CLI and server, which power fine tuning and inference pipelines for multimodal LLMs, image models, and video models on Oxen.ai.

//! # oxen clean
//!
//! Remove untracked files and directories from the working tree. Analogous to `git clean -fd`.
//!
//! Without `opts.force` the command is a dry run: it reports what *would* be removed but makes
//! no filesystem changes. Pass `force = true` to actually delete.
//!
//! Invariants:
//!
//! - Never touches `.oxen/`.
//! - Never touches tracked files (candidates come only from `StagedData.untracked_*`).
//! - Never touches files matched by `.oxenignore` (inherited via `oxen status`'s existing
//!   filter; `clean` does not re-filter).
//! - An untracked directory is only removed whole when its entire subtree is untracked —
//!   `oxen status` already classifies partially-tracked directories differently.
