About:
Uru is a cross-platform command-line tool that manages multiple Ruby installations on Windows, Linux, and macOS. It allows developers to seamlessly switch between different Ruby versions and implementations for various projects. This ensures environment consistency and simplifies testing across different Ruby runtimes without conflicts.

Key Features:

Cross-platform support for Windows, Linux, and macOS
Seamless switching between multiple Ruby versions
Support for MRI, JRuby, and other Ruby implementations
Lightweight command-line interface
No shell configuration required

Use Cases:

Managing multiple Ruby versions for different development projects
Testing applications across different Ruby implementations
Setting up consistent Ruby environments for CI/CD pipelines

Alternatives:

rbenv – rbenv is Unix-focused and requires shell modifications, while Uru is cross-platform with simpler setup
RVM – RVM is more feature-rich but heavier, Uru is lightweight and cross-platform compatible
chruby – chruby is Unix-only and simpler, Uru provides broader platform support
