# vm.scm

Scheme implementation of Varvara.

It is closely based on [uxnmin.c](https://wiki.xxiivv.com/etc/uxnmin.c.txt).

Currently it supports:

 * console stdin, stdout, and stderr
 * command-line arguments

# goals

The main goals of this project are:

 * portability across Scheme implementations
 * implementations simplicity and correctness
 * support bootstrapping uxn
 
Secondary goals are:

 * supporting more devices
 * emulator performance

# scheme dialects

The default dialect used is [Chicken Scheme](http://www.call-cc.org/).

The source code contains shims for [Guile](https://www.gnu.org/software/guile/), [Chibi-scheme](http://synthcode.com/scheme/chibi), and [Chez Scheme](https://cisco.github.io/ChezScheme/). By commenting out the Chicken stanza and uncommenting a different one other Scheme dialects may be supported.
