KLaSC (pronounced "classy") is a compliance test suite for implementations of KLambda, the kernel Lisp upon which the Shen programming language is implemented.
The specification for KLambda is contained in the Official Shen Standard. Clarifications to the specification may be found on the KLambda page of the Shen Wiki.
After cloning the repository, use the following commands to install KLaSC's dependencies:
gem install bundler
bundle install
The current version of KLaSC expects to interact with a Shen REPL. By
default, it assumes that the command to launch a Shen REPL is
shen. This can be overridden with the SHEN_COMMAND environment
variable.
KLaSC is implemented with RSpec and does not yet have a wrapper script. To run it, simply run RSpec:
bundle exec rspec
Use the -fs argument to RSpec to produce documentation-style output
instead of progress dots.
The interpretation of the KLambda specification as tested by KLaSC is in the process of being vetted via discussions on the Shen Online News Group.
All of the tests pass on the Shen-CLisp port, but this does not necessarily mean that they all reflect required behavior. When in doubt, consult the news group.
The test driver is only working against Shen-Clisp. Shen-SBCL and ShenRuby both fail to connect properly. Fixing this is next on the list of things to do.
The following are the priority for near-term development:
- Support for testing stand-alone KLambda implemenations outside of
Shen.
- This is intended primarily to aid KLambda implemenators who do not yet have an implemenation that is complete enough to run Shen.
- Adding coverage of the remaining Klambda primitives
- Full vetting and removal of the above disclaimer
