Clasp is a Common Lisp implementation that interoperates with C++ and uses LLVM for just-in-time (JIT) compilation to native code.

See http://drmeister.wordpress.com/2014/09/18/announcing-clasp/ for the announcement.

Clasp is not yet a full ANSI compliant Common Lisp - if you find differences between Clasp and the Common Lisp standard they are considered bugs in Clasp and please feel free to report them.

Libraries that clasp depends on can be obtained using the repository: externals-clasp
https://github.com/drmeister/externals-clasp.git
You can build externals-clasp or you can use the makefile as a guide configure your environment by hand.

BUILDING CLASP

Clasp has been compiled on OS X 10.9.5 using Xcode 6.0.1

Clasp has been compiled on recent (post 2013) versions of Ubuntu Linux

To build Clasp from within the top level directory do the following.

1. Copy local.config.darwin or local.config.linux to local.config

2. Edit local.config and configure it for your system

3. Type: make to build mps and boehm versions of Clasp
   or type: make-boehm to make the boehm version of Clasp
   or type: make-mps to make the MPS version of Clasp

4. Install the directory in $PREFIX/MacOS or $PREFIX/bin (from local.config) in your path
   then type: clasp_mps_o to start the Lisp REPL of the MPS version of Clasp
   or type: clasp_boehm_o to start the Lisp REPL of the Boehm version of Clasp

5. Type: (print "Hello world") in the REPL and away you go (more documentation to follow)
