A Safer Scheme Interpreter, Part 2

Posted by kernelbob on January 3, 2011

In my last post, I promised to explain how my Scheme interpreter, Schetoo, can automatically verify that its instructions are restartable.  But first, some background.

A Safer Scheme Interpreter

Posted by kernelbob on January 2, 2011

In the first half of 2010, I wrote a Scheme interpreter which I called Schetoo. It is a sequel to an interpreter called kbscheme, which I worked on off-and-on in 2008 and 2009. Both are written in C.

You can see them both on github.

I undertook these projects to learn more about Scheme, interpreters, and garbage collection. Along the way, I came up with an interesting technique to make interpreter implementation less error-prone. That’s what I want to write about today.

Son of Scheme: Introducing Schetoo

Posted by kernelbob on February 13, 2010

I’ve started a new Scheme project. This one is called Schetoo. The name has connotations of “Scheme Two”, “me too”, and “Gentoo” (a hardcore Linux distribution and a breed of penguin).

A ‘blogger named Peter Michaux started a series in January called Scheme from Scratch. His goal was to write a very quick and dirty Scheme, just enough to bootstrap a Scheme compiler. I read his postings and decided to get started again.

Schetoo is similar in concept to my first Scheme, kbscheme. In fact, I reused a fair amount of code to get Schetoo up and running faster. But at the same time, I’m applying what I learned to try to get a better design.

I’ve published the code on GitHub.
