Carp

Carp is a small programming language designed to work well for interactive and performance sensitive use cases like games, sound synthesis and visualizations.

The key features of Carp are the following:

• No garbage collection or runtime system, all memory management is deterministic and compiled into the final library or executable
• Static, inferred types system that enables very fast code execution and fewer runtime errors
• Dynamic code loading and live evaluation allows interactive (REPL-driven) development of your program
• No hidden performance penalties, everything that can slow down your program is explicit and visible in the code
• Ownership system that enables a functional programming style with the performance characteristics of C
• Very good integration with C libraries

The Language

Carp is heavily inspired by languages like Clojure, Scheme, Haskell, ML and Rust. Here's a sample program:

(defn main ()
  (println "Hello!"))

The Compiler

Carp is very tightly integrated with it's compiler which itself is written in a dynamic version of Carp (the dynamic version is implemented in C). To compile or work on a Carp program you start the Carp compiler system which puts you in the compiler REPL. Everything you want to do with your program can be controlled from here.
