Top 3 Lean Lean Projects

  • lean4

    Lean 4 programming language and theorem prover

    Project mention: Where does "def" for functions come from and why? | reddit.com/r/ProgrammingLanguages | 2023-01-21

    Lean is another language that uses the def keyword, but they use it as a more general "give this term a name" rather than "make a function" ``` -- constant definition def five : ℕ := 5

  • mathlib

    Lean mathematical components library

    Project mention: Lean – Theorem Prover | news.ycombinator.com | 2023-01-20

    I think they end up similar. Although Lean 3 is much more geared towards writing proofs with the addition of mathlib [0] which aims to be a library of formalized mathematics.
