Cyclone is an experimental Scheme-to-C compiler that uses the Cheney on the MTA technique to implement full tail recursion, continuations, and generational garbage collection.

Getting Started

1. To install Cyclone on your machine for the first time use cyclone-bootstrap to build a set of binaries.

2. After installing you can run the cyclone command to compile a single Scheme file:

    $ cyclone examples/fac.scm
    $ examples/fac
    3628800
   

   And the icyc command to start an interactive interpreter:

    $ icyc
   
                  :@
                @@@
              @@@@:

           .@@@+@@@      Cyclone

3. If you need help learning the Scheme language try a classic textbook such as Structure and Interpretation of Computer Programs.

   Also, check out the features page for a list of language features currently implemented.

Documentation

For more information about the Scheme language implemented by Cyclone, see the R⁷RS Scheme Specification.

The features page lists the language features currently implemented.

The development page contains instructions for hacking on Cyclone.
