* indicates functions defined in CommonLib.lisp. It is only available in REPL mode. See the 'Running' section below on how to make these functions available in the REPL

Running

You will need GHCI installed.

$> git clone https://github.com/neerajrao/common-lisp-repl-haskell.git
$> cd common-lisp-repl-haskell

You can now try one of the following

Compiles source, creates the clisp executable and runs it

$> make run

Compiles source, creates the clisp executable. Does NOT run it.

$> make

Run in REPL mode

$> clisp

Run in single-command mode

$> clisp "your common lisp expression"

If you want the functions defined in CommonLib.lisp (the ones marked by ^* in the list of supported functions above) to be available, you must load it after the REPL starts

clisp>> (load "src/CommonLib.lisp")

Details

This project closely follows the excellent wikibook Write Yourself a Scheme in 48 Hours by Jonathan Tang.

There are some important differences:

• Support for Lisp-2 namespaces (distinct variable and function namespaces) (instead of Scheme's Lisp-1 namespaces)
• Support for Common Lisp functions (instead of Scheme functions)
