xgqt@gentoo.org Maciej Barć Fennel is a lisp that compiles to Lua. It aims to be easy to use, expressive, and has almost zero overhead compared to handwritten Lua. Full Lua compatibility - You can use any function or library from Lua. Zero overhead - Compiled code should be just as or more efficient than hand-written Lua. Compile-time macros - Ship compiled code with no runtime dependency on Fennel. Embeddable - Fennel is a one-file library as well as an executable. Embed it in other programs to support runtime extensibility and interactive development. At https://fennel-lang.org there's a live in-browser REPL you can use without installing anything.
