This project aims to build a complete executable specification of the Io Programming Language. We do this so that the canonical IoVM of the day doesn't slow progress by stagnating its own development, when other implementations may put forward ideas to further the language. There are presnetly several implementations of Io under active development.
@stevedekorte started the Io programming language in 2002, and has implemented the most popular implementation; the canonical version. The goal of this project is to get rid of any one canonical version, and provide a base for all implementations to conform to, to be considered implementations of the Io programming language. This would apply to Steve's version as well.
Steve and I have talked about this project in brief, and we're both ok with taking it in this direction. More details will be forthcoming as we pick our testing framework, and start writing the tests. In general, a few things we want to do.
0.1.0 is the latest version of the specification.
- Test the core semantics of the language. Things like message sending, argument handling, exceptions, etc.
- Test the required APIs. This won't include any addons, for instance as they're not part of the language.
- Most important, this should function across implementations.
A few things to note. We use a primitive testing tool which is a fork of Jonathan Wright's iospec2. If you want to help us build on that, awesome! We could use some help building up our table of expectations.
If you instead (or in addition to) want to help us build up the language spec, then that'd be great. The filename convention is
thingYoureTesting-spec.io. Anything else and it won't be picked up by the automatic runner (feel free to improve that if you want too). Look at other specs for tips on how to write specs. If you want some more expressive power, or things like mocks, we'll need to build those into the testing tool. Send pull requests when you run into those and fix them.
