The Fenius programming language, 2024.a edition

Fenius is a programming language I play with as a hobby in my free time. It aims to mix elements of functional and object-oriented programming, a controlled but not restrictive approach to mutability, and language extensibility through Lisp-style macros in a conventional, non-Lispy syntax.

This is very much a work in progress.

For more information, have a look at the posts with the 'fenius' tag in my blog.


You must have SBCL installed. On Debian, you can install it with sudo apt install sbcl. On Mac, you can use brew install sbcl.

Clone this repo with submodules and run the build script:

git clone --recurse-submodules https://elmord.org/code/fenius
cd fenius

That's it! If everything works alright, you should have a fenius binary in the current directory.
