About

Rivendell adds useful functionality to elvish to take your shell to the next level!

🌈 functional bits: high-level functions which encapsulate common design patterns.
πŸ’€ lazy iterators: transducer-inspired iterators which allow you to represent infinite sequences.
πŸ“ˆ visual aids: sparklines & histograms.
πŸ”§ plus a toolbelt of common utility functions which operate on strings, lists, and maps.
