Modulation, an explicit dependency management tool for Ruby, has just reached version 1.0. Modulation is already used in production, and personally I find it a great help in managing the code bases of my different Ruby projects.

Modulation provides the following features:

• Complete isolation of each module
• Explicit exporting and importing of methods and constants
• Lazy Loading of modules
• Hot module reloading for a faster development process
• Module mocking for testing
• Dependency introspection at runtime
• Packing tool for packing entire applications into a single Ruby file
