Refactored the application to improve performance, maintainability, and binary size. Key Changes: - **Core Algorithm**: Switched to a parallel, single-pass tree construction algorithm for O(N) traversal. - **Architecture**: Extract core logic from `main.rs` to `lib.rs` to enable unit testing. - **Testing**: Added comprehensive unit tests and integration tests (`tests/cli.rs`) covering CLI arguments and output formats. - **Benchmarking**: Added `criterion` benchmarks for performance tracking. - **Dependencies**: - Removed `walkdir` (logic replaced by `ignore` + custom tree). - Removed `humansize` (consolidated to `byte-unit`). - Replaced `chrono` with lightweight `time` crate. - Removed unused `atty`. - **Reporting**: Optimized CSV and JSON output for correctness and zero-copy performance. - **Documentation**: Updated CHANGELOG.md and bumped version to 0.2.0.

## [0.2.0] - 2026-01-22
|
|
|
|
### Changed
|
|
- Refactored core traversal logic to a **single-pass, in-memory tree construction** algorithm. This visits every file exactly once, replacing the previous $O(N \times Depth)$ behavior with $O(N)$.
|
|
- Switched default CSV output to use the `csv` crate for robust escaping (fixes issues with filenames containing commas).
|
|
- Optimized JSON output to use zero-copy serialization, improving performance and memory usage.
|
|
|
|
### Added
|
|
- Added `MANUAL.md` with comprehensive usage documentation.
|
|
- Added comprehensive test suite (unit and integration tests).
|
|
- Added performance benchmarks using `criterion`.
|
|
|
|
### Removed
|
|
- Removed `walkdir` dependency (replaced by `ignore::WalkBuilder` for all traversal).
|
|
- Removed `humansize` (consolidated to `byte-unit`).
|
|
- Removed `chrono` (replaced with lightweight `time`).
|
|
- Removed `atty` (unused).
|
|
|
|
|
|
## [0.1.0] - 2026-01-22
|
|
|
|
### Added
|
|
- Core directory traversal and size calculation logic.
|
|
- Parallel processing using `rayon` for high performance.
|
|
- Rich table output format using `comfy-table` with colored entries.
|
|
- Recursive depth control via `-d`/`--depth`.
|
|
- Minimum size filtering via `-m`/`--min-size`.
|
|
- Multi-column sorting support (`--sort`).
|
|
- Relative path display by default, with `-f`/`--path-full` override.
|
|
- "Total size" summary with dual units (Binary/Decimal) and block counts.
|
|
- Concurrency control via `-j`/`--threads`.
|
|
- `.gitignore` and `.ignore` file support via `-i`/`--ignore`.
|
|
- Multiple output formats: Text (Table), CSV, JSON (`--format`).
|
|
- Save to file functionality with auto-naming (`--save`).
|
|
- Shell completion generation (`--completions`).
