Minerva
An implementation of R5RS Scheme in Common Lisp and C, inspired by the paper "An Incremental Approach to Compiler Construction", Abdulaziz Ghuloum, Proceedings of the 2006 Scheme and Functional Programming Workshop.
Minerva compiles Scheme expressions into x86 (32-bit) binaries along with a currently very simple runtime.
The implementation is far from being complete right now, you can see the supported subset of the language in the tests suite.
Minerva was tested on SBCL under Windows and Linux, other CL implementations and operating systems may or may not work.
Install
The runtime is written in C, and the compiler depends on GNU as and ld to produce executables from emitted assembly code, so you will need to install either MinGW on Windows or gcc-multilib on Linux.
If you are using Quicklisp, clone the repository to your local-projects directory. Otherwise you can clone it wherever you want and load the system manually:
(asdf:load-asd #p"/path/to/Minerva/minerva.asd")
(asdf:load-system :minerva)
If you want to use the test suite, set your preferred directory for intermediate files in tests.lisp by changing the *intermediates-pathname* definition.
Usage
To run the test suite:
(minerva:run-all-tests)
To compile an expression:
(minerva:compile-scheme-expr <your-expression-in-quote> <path-to-the-new-executable>)
For example:
(minerva:compile-scheme-expr '(+ 1 1) "/home/foo/bar")
produces an executable called bar in the directory /home/foo/ that prints 2.
