ParenScript for Narwhal
As of commit d9860869e014ae85e2ac0833268d38b6ee584f4a it assumes both that the Common Lisp implementation you are using is SBCL and that you already have ParenScript installed and require-able. There are also still issues with requiring the module, but the REPL works like a charm.
This is for installing on Ubuntu (and probably other Debian systems). If you can tell me the equivalent steps for other distros and OS's, feel free to tell me.
sudo apt-get install sbcl touch ~/.sbclrc
Add this to your .sbclrc file:
Open SBCL and install ParenScript:
sbcl * (require :asdf-install) T * (asdf-install:install :parenscript)
Answer the questions ASDF-INSTALL will ask you about where to install, etc...
Go to the path that contains your Narwhal packages and add ParenScript:
cd path/to/your/narwhal/packages git clone git://github.com/fitzgen/parenscript-narwhal.git parenscript
Open up the ParenScript REPL:
You should see a shell something like this:
ps> (print "Hello World") ... ... Hello World ps>
