Rash

概要

Rash is a powerful bidirectional shell safety tool designed to solve the inherent difficulties of writing safe and reliable shell scripts. It allows developers to write shell scripts in Rust, which are then transpiled into deterministic, POSIX-compliant shell code with automatic safety guarantees, preventing common issues like shell injection and word splitting. Alternatively, Rash can purify existing legacy bash scripts, automatically transforming unsafe patterns into secure, idempotent, and deterministic equivalents, ensuring consistent and reproducible execution across any POSIX-compliant system without runtime dependencies.

主な機能

• ShellCheck Compliant: All generated or purified scripts pass strict ShellCheck linting.
• Automatic Safety: Protection against shell injection, word splitting, and glob expansion.
• Zero Runtime Dependencies: Generated scripts function on any POSIX shell environment.
• Deterministic Output: Guarantees identical script output for the same input every time.
• 21 GitHub stars
• Beyond Linting: Full Abstract Syntax Tree (AST) semantic understanding for code transformation, not just warnings.

ユースケース

• Transforming existing legacy and potentially unsafe bash scripts into secure, purified code.
• Automating CI/CD pipelines with safe, deterministic, and reproducible scripts.
• Creating robust and idempotent system configuration and deployment scripts.
