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:
- Automatic and deterministic memory management (no garbage collector or VM)
- Inferred static types for great speed and reliability
- Live reloading of code, REPL-driven development, a fun and helpful workflow
- Ownership tracking enables a functional programming style while still using mutation of cache friendly data structures under the hood
- No hidden performance penalties – allocation and copying is explicit
- Very good integration with exisiting C code
- Installation - how to build the Carp compiler
- The Compiler Manual - how to compile code and configure your projects
- Carp Language Guide - syntax and semantics of the language
- game.carp - a more complex example

step (/ 1f (itof steps))]
(for (i 0 steps)
(let [r (* step (itof i))

(draw-line (* r (cosf (* t r)))
(* r (sinf (* t r)))
(* r2 (cosf (* t r2)))
(* r2 (sinf (* t r2))))))))
(defn spin []
(glfw-app "Spin" init tick draw default-on-keys))To build this example, save it to a file called 'example.carp' and load it with (load-lisp "example.carp"), then execute (bake-exe spin) to build an executable, or (spin) to run the program directly from the REPL.
