## About

Carp is a 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

* 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 are explicit

* Straightforward integration with existing C code

* Lisp macros, compile time scripting and a helpful REPL

## A Very Small Example

```clojure

(load-and-use SDL)

(defn tick [state]

  (+ state 10))

(defn draw [app rend state]

  (bg rend &(rgb (/ @state 2) (/ @state 3) (/ @state 4))))

(defn main []

  (let [app (SDLApp.create "The Minimalistic Color Generator" 400 300)

        state 0]

    (SDLApp.run-with-callbacks &app SDLApp.quit-on-esc tick draw state)))

```

For instructions on how to run Carp code, see [this document](docs/HowToRunCode.md).
