This is the main source code repository for SICL. It contains the compiler, standard library, and documentation.
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.
-
Make sure you have installed the dependencies:
- A recent 64-bit version of SBCL
-
Make sure your SBCL has a 10GB heap by passing --dynamic-space-size 10000 to SBCL when it starts up.
-
Clone the source with
git
:$ git clone https://github.com/robert-strandh/SICL $ cd SICL
-
Make sure the top-level directory can be found by ASDF.
-
Compile the boot system as follows:
(asdf:load-system :sicl-boot)
-
Change the package for convenience:
(in-package #:sicl-boot)
-
Create an instance of the BOOT class:
(defparameter *b* (let ((sicl-extrinsic-environment::*cache-p* t)) (make-instance 'boot)))
Creating the first environment will take a few minutes. In particular, it will seem that it is stuck when loading a few files, especially remf-defmacro.lisp.
-
Start a REPL:
(sicl-extrinsic-environment::repl (r4 *b*) (r4 *b*))
- Cleavir is an implementation-independent compilation framework for Common Lisp. To use, make sure that you that you are in the SICL directory and load the neccesary packages and file.
(ql:quickload '(cleavir-generate-ast cleavir-ast-to-hir cleavir-hir-interpreter))
(load "Code/Cleavir/Environment/Examples/sbcl.lisp")
- Now you can compile Common Lisp expressions like
(cleavir-hir-interpreter:interpret-hir (cleavir-sbcl-environment::compile-cleavir '(lambda () (+ 32 10))))
SICL releases are here.
Check the Documentation directory for more information.
The SICL community members are usually on various IRC channels. There is now a dedicated channel called #sicl, but discussion can also be found on #lisp, #clasp, and #sicl.
