winget install --id=Lean.Lean -e Lean is a functional programming language that makes it easy to write correct and maintainable code. You can also use Lean as an interactive theorem prover. Lean programming primarily involves defining types and functions. This allows your focus to remain on the problem domain and manipulating its data, rather than the details of programming. Lean has numerous features, including: - Type inference - First-class functions - Powerful data types - Pattern matching - Type classes - Extensible syntax - Hygienic macros - Dependent types - Metaprogramming framework - Multithreading - Verification: you can prove properties of your functions using Lean itself
Lean is a functional programming language designed to simplify writing correct and maintainable code while also serving as an interactive theorem prover. Its primary focus is on defining types and functions, allowing developers to concentrate on problem-solving rather than low-level programming details.
Key features of Lean include type inference, which reduces boilerplate by automatically deducing types; dependent types, enabling precise specifications for correctness; and a powerful metaprogramming framework that allows users to extend Lean's functionality. Additionally, its support for verification lets programmers prove properties of their functions directly within the language.
Ideal for mathematicians, researchers, and software engineers seeking precise code and formal proofs, Lean provides a robust environment for building systems with high assurance in correctness and maintainability. It can be installed via winget, making it accessible for integration into workflows focused on rigorous development practices.
