Idris 2 is a purely functional programming language with first-class types and full dependent types, designed for type-driven development. This repository contains the compiler and toolchain, installable via the 'pack' package manager.

Use cases

• write programs with dependent types
• learn type-driven development
• formally verify program properties with the type checker
• prototype purely functional programs
• explore dependent type theory in practice

When to choose

• you need expressive dependent types to encode program invariants
• you want a purely functional language for research or teaching
• you want the compiler to guide program construction from types

When to avoid

• you need a general-purpose mainstream language with a large ecosystem
• you need high runtime performance for production services
• your team is unfamiliar with functional programming
