This directory contains the PLT Redex implementation of the R6RS operational semantics and a test suite for the semantics. It runs in DrScheme v4.x. This version of the semantics matches the r5.92rs report. == r6rs.scm: the semantics itself. == r6rs-tests.scm: the test suite for the semantics. Use: mzscheme -t r6rs-tests.scm -m to run the tests and see a single period shown per test run (each test that explores more than 100 states shows a colon for each 100 states it explores). To see a more verbose output (that shows each test), use: mzscheme -t r6rs-tests.scm -m #t == show-examples.scm: use this file to explore particular examples in a GUI. Its content shows how to use it and gives a few examples. Either run it in DrScheme's module language, or like this from the commandline: mred show-examples.scm == test.scm: test suite infrastructure For details on PLT Redex see: http://redex.plt-scheme.org/ Although note that this version of the semantics uses an old version of Redex.
