SICL: A new Common Lisp Implementation

This is the main source code repository for SICL. It contains the compiler, standard library, and documentation.

What is SICL?

SICL is a new implementation of Common Lisp. It is intentionally divided into many implementation-independent modules that are written in a totally or near-totally portable way, so as to allow other implementations to incorporate these modules from SICL, rather than having to maintain their own, perhaps implementation-specific versions.

Quick Start

  1. Make sure you have installed the dependencies:

    • A recent 64-bit version of SBCL
  2. Clone the source with git:

    $ git clone https://github.com/robert-strandh/SICL
    cd SICL 


SICL releases are here.

Check the Documentation directory for more information.
