A portable debugger for the Scheme language. It presents the user with an interactive interface that lets him or her examine and change values of variables, set breakpoints, and single step evaluation. Psd is designed to be run within GNU Emacs, which...

A generator for LR(k) and SLR(k) parsers in Scheme. The generated parsers perform error recovery, and are highly efficient. They result from the general parser by an automatic program transformation called partial evaluation. This guarantees consisten...

A partial evaluator for a pure (side effect free) subset of Scheme, written primarily by Charles Consel. Some of its main features are polyvariant binding-time analysis, treatment of higher-order functions and partially static data structures, colored...

An interactive symbolic mathematics program. It can manipulate and simplify equations, scalars, vectors, and matrices of single and multiple valued algebraic expressions containing numbers, variables, radicals, and algebraic differential, and holonomi...

A portable Scheme library providing compatibility and utility functions for standard Scheme implementations. By Audrey Jaffer, author of SCM.

A module proposal for Scheme by Audrey Jaffer.

A whole handfull of Scheme programs and applications, including Treaps ("A sorted dictionary data structure based on randomized search trees."), Scheme database interfaces, parsing utilities for CGI and XML, binary I/O and applications, POSIX interfac...

A digital logic simulator written for the SCM Scheme implementation.

A CLOS-like object system for MzScheme. Many other extensions like a generalized set. (a la SRFI-17).

A partial evaluation system for Scheme: Given a program P and a specification of which of the inputs are known in advance, PGG outputs a program generator which accepts the known inputs of P and outputs a specialized version of P. PGG is fully automat...
