Bob is a suite of implementations of the Scheme language in Python and C++. It currently includes the following Python components:
- A Scheme interpreter
- An implementation of a stack-based virtual machine called the "Bob VM"
- A compiler from Scheme to Bob VM bytecode
- A serializer and deserializer for Bob VM bytecode
- A compiler from Scheme to WebAssembly
In addition, Bob comes with another version of the VM, implemented in C++. It's called "BareVM". Bob itself is a fully usable implementation of Scheme in pure Python; BareVM is an optional component.
There's some documentation in the doc/ directory in the source.
