Carp
WARNING! This is a research project and a lot of information here might become outdated and misleading without any explanation. Don't use it for anything important!
Update (June 26, 2017): The total rewrite is now live; if you want to look at the old version, it's under the branch named "c" in this repository.
About
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
- 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

A Small Example
(use IO)
(use Int)
(use String)
(defn main []
(do (println "~ The number guessing game ~")
(print "Please enter a number between 1 - 99: ")
(let [play true
answer (random-between 1 100)]
(while play
(let [guess (get-line)
num (from-string &guess)]
(if (= &guess "q\n")
(do
(println "Good bye...")
(set! &play false))
(do
(cond (< num answer) (println "Too low.")
(> num answer) (println "Too high.")
(println "Correct!"))
(print "Please guess again: "))))))))
To build this example, save it to a file called 'example.carp' and load it with (load "example.carp"), then execute (build) to build an executable, and (run) to start.
