Fennel: A Lisp-like Enhancement for Lua
2025-04-13
Fennel is a programming language running on the Lua runtime. It leverages Lua's efficiency and lightweight nature while addressing some of Lua's shortcomings through Lisp-style syntax and improved design. Fennel employs a paren-first syntax, eliminating operator precedence ambiguity and early returns. Stricter variable management prevents accidental global variable use. Improvements include table notation, looping constructs, function argument checks, data structure destructuring, and pattern matching, enhancing code readability and maintainability. While Fennel offers a powerful macro system, it's often unnecessary. In short, Fennel provides a safer, cleaner way to program in Lua.
