big-bang

Big Bang source repository

dde

Pure Demand Operational Semantics

whayrf

Proof-of-concept implementation of function patterns

odefa

sato

Sato, the Symbolic Analysis Typechecker for Odefa, dynamically locates type errors using demand-driven symbolic execution.

CoPylot

pdr-programming

A metaprogramming library which generates regular PDS descriptions based upon user-written straight-line code.

pds-reachability

A library for performing efficient reachability queries on abstractly specified push-down systems.

toy-language

A common basis for toy language development using a simple, shallow ANF

toy-language-dr

A derivative of the toy-language repository which has "proper" deep records rather than shallow records.
