## 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)))
|
||
```
