fsweep 0.3.3

An advanced workspace cleanup tool for developers to reclaim disk space.

🧹 fsweep

fsweep is your friendly neighborhood workspace cleanup tool! It's designed to help developers mop up bulky development artifacts and sweep away disk-space-hogging junk with ease.

Whether it's a mountain of node_modules, a forgotten venv, or stale build caches, fsweep identifies the mess and helps you reclaim your disk space in seconds.

📦 Installation

fsweep is best managed with uv. If you don't have it yet, get it from astral.sh/uv.

uv tool install fsweep

⚡ Quickstart (30 seconds)

Safe first run (dry-run, current directory):

uv run fsweep

Machine-readable dry-run:

uv run fsweep --output json

Destructive run with hard-delete:

uv run fsweep --delete --yes-delete

Destructive run with recoverable trash mode:

uv run fsweep --delete --trash --yes-delete

The default scan path is your current working directory (.).

Options

Option	Shorthand	Description	Default
--path		The directory to scan for cleanup.	.
--force	-f	Skip final destructive confirmation prompt.	False
--dry-run / --delete	-d	Simulate cleanup (default) or enable destructive mode.	True
--trash		Move matched folders to ~/.fsweep_trash instead of hard delete.	False
--interactive		Select matched folders before execution.	False
--use-index / --no-index		Enable/disable scan size cache index.	True
--index-file		Path to scan index JSON file.	<scan_path>/.fsweep-index.json
--output		Output format: table or json.	table
--report		Write a markdown run report to a file.	unset
--config		Load a TOML config file.	unset
--target-folder		Add custom target folder names (repeatable).	[]
--exclude-pattern		Exclude glob patterns from scan (repeatable).	[]
--protected-path		Protect paths from scan/deletion (repeatable).	[]
--yes-delete		Required for destructive runs.	False
--best-effort		Continue and exit successfully even if deletes fail.	False
--max-delete-count		Max folders allowed in one destructive run.	50
--no-delete-limit		Override --max-delete-count.	False

⚙️ Config File (fsweep.toml)

fsweep loads config in this order (later wins):

1. ~/.config/fsweep/fsweep.toml
2. <scan_path>/fsweep.toml
3. --config /path/to/fsweep.toml
4. CLI flags

Example:

[fsweep]
target_folders = ["node_modules", "venv", "vendor_cache"]
exclude_patterns = ["**/.git/**", "**/keep/**"]
protected_paths = ["important", "../do-not-touch"]
max_delete_count = 75
no_delete_limit = false

protected_paths are resolved relative to the config file that defines them. If you want to include generic names such as build, dist, out, bin, or obj, add them explicitly with target_folders.

📤 JSON Output Contract

Use --output json for scripts/automation.

• schema_version: currently "1"
• summary: totals, counts, and effective action
• items[]: per-folder path, size, action, status, and optional error
• error responses also use JSON with error and exit_code

⚖️ Dry-run Parity Guarantee

fsweep now includes a dry-run parity test that guarantees the matched set in dry-run and destructive mode is identical for equivalent flags and path.

📈 Benchmark + Indexing

• --use-index caches directory size calculations in <scan_path>/.fsweep-index.json to speed repeated scans.
• Use --no-index to benchmark raw scan performance.
• Opt-in benchmark suite:

FSWEEP_BENCHMARK=1 ./.venv/bin/python -m pytest tests/test_fsweep/test_benchmark.py -q

🧹 What does it sweep?

fsweep knows exactly which corners to sweep. It currently targets:

• JavaScript/TypeScript: .astro, .eslintcache, .next, .nuxt, .parcel-cache, .pnpm-store, .svelte-kit, .turbo, .vercel, .vite, .wrangler, node_modules
• Python: .ipynb_checkpoints, .mypy_cache, .nox, .pytest_cache, .ruff_cache, .rumdl_cache, .tox, .uv-cache, .venv, __pycache__, venv
• Build/Test Artifacts: .cache, .nyc_output, coverage, htmlcov
• JVM/.NET/Rust: .gradle
• Infrastructure-as-Code: .aws-sam, .serverless, .terraform, .terragrunt-cache

🚀 Key Features

• 🔍 Intelligent Scanning: Recursively hunts down common "junk" folders across your projects.
• 💰 Size Estimation: Calculates exactly how much space you'll recover before you commit.
• 📊 Rich Terminal UI: Presents findings in beautiful, easy-to-read tables thanks to Rich.
• 🛡️ Safety First: Includes a robust --dry-run mode and confirmation prompts to ensure your precious source code stays safe.
• 💨 Reach + Speed: Supports Python 3.10+ and keeps scan/deletion fast.
• 🚫 .fsweepignore: Skip an entire directory tree by placing an empty .fsweepignore file in its root.
• 🔧 System Command: Run fsweep system to get tips for cleaning global tool caches (like Docker or uv).

🧪 Development

Ready to help improve the fsweep? Here's how to keep the codebase as clean as your workspace.

git clone https://github.com/drew-simmons/fsweep.git
cd fsweep

uv sync

🛠️ Tech Stack

• Python 3.10+
• Typer: For a clean and intuitive CLI experience.
• Rich: For beautiful terminal output, tables, and progress indicators.
• uv: For lightning-fast dependency management.

Running Tests

uv run pytest

Exit Codes

• 0: successful run (or dry-run simulation complete)
• 1: safety check failure or invalid invocation
• 2: one or more deletions failed (unless --best-effort is set)

Linting & Formatting

We use Ruff to keep things tidy:

uv run ruff check .
uv run ruff format .
uv run rumdl fmt .

Type Checking

Keep the types in check with ty:

uv run ty check .

[!TIP] uv run prek -a runs all the above linting and formatting.

🔐 Safety Model

• Default mode is non-destructive (--dry-run).
• Destructive mode requires --delete --yes-delete.
• Optional --trash mode is destructive but recoverable.
• fsweep refuses to sweep / and your home directory root.
• Destructive runs are capped by --max-delete-count unless overridden.
