Redex: Debugging Operational Semantics

Robert Bruce Findler

PLT Redex consists of a domain-specific language for specifying reduction semantics, plus a suite of tools for working with the semantics.

This is a reference manual for Redex. See for a gentler overview. (See also the examples subdirectory in the redex collection.)

To load Redex use:

 (require redex)

which provides all of the names documented in this library.

The module redex/reduction-semantics provides only the non-GUI portions of what is described in this manual (everything except the last two sections), making it suitable for use with mzscheme scripts.
