The ViviFire Programming Language

ViviFire is a brand new open-source programming language with modern features and a familiar syntax. It offers object-oriented programming with genericity and traits, modularity, units of measure, and more.

Currently, ViviFire is at an alpha stage of development. The language is still evolving, and may change dramatically before it's done. If you are interested in how a language is created, join us and help make it great!

ViviFire is released under the MIT license.
