rasa-0.5.1 is not a library.
Rasa scans your filesystem for build artifacts, caches, logs, and other space hogs left behind by development tools — then lets you interactively pick what to delete.
Highlights
- 85 plugins — languages, package managers, databases, IDEs, browsers, system caches
- Interactive TUI — browse, sort by size, toggle unsafe items, filter by plugin
- Fast — parallel filesystem walk with SQLite cache for instant re-runs
- Safe by default — every target is labelled recoverable or unsafe
- Configurable — CLI flags or
~/.rasa/config.toml
Installation
Quick start
# Scan home directory with defaults
# Only Node and Cargo artifacts, 500 MB minimum
