WASI Multi-Utility & Shell (sl-rust)

A collection of high-performance, modular utilities and an interactive shell, all optimized for WASI (WebAssembly System Interface).

Project Overview

This workspace contains several crates designed to provide a rich command-line environment in WASI-compatible runtimes (like wasmtime, wasmer, or the browser).

• wasibox: An umbrella multi-call binary (similar to BusyBox) that integrates all utilities.
• wasi-shell: A modular REPL with support for piping (|) and redirection (>, >>).
• wasibox-core: A shared library of essential POSIX-like utilities (ls, cat, grep, etc.) using an injectable IoContext.
• sl-rust: A Rust implementation of the classic SL (Steam Locomotive) animation.

Features

• Piping & Redirection: Full support for standard shell IO operators in wasi-shell.
• Modular Utilities: Over 30 utilities that can be used as standalone binaries or linked into the wasibox.
• WASI Optimized: Designed from the ground up to respect WASI capabilities and limitations (e.g., restricted filesystem access).
• Cross-Platform: Works on Native (Windows/Linux/macOS) and WASI.
