* Description
A Spacemacs contribution layer providing Common Lisp support via [[https://github.com/slime/slime][SLIME]].

* Install
If you have previously installed slime in any other way, it is recommended that
you uninstall it before proceeding. You should clean up any config files tied to
slime that are left behind as well. Linux users can just purge the slime package
if it was a distribution install.

To use this configuration layer, add it to your =~/.spacemacs=. You will need to
add =common-lisp= to the existing =dotspacemacs-configuration-layers= list in this
file.

This layer defaults to using [[http://www.sbcl.org/][sbcl]]. If you want to use a different implementation
of Common Lisp, you can specify it in your =~/.spacemacs=

#+BEGIN_SRC emacs-lisp
  (defun dotspacemacs/user-config ()
    (setq inferior-lisp-program "/path/to/your/lisp"))
#+END_SRC

* Key Bindings
** Working with lisp files (barfage, slurpage & more)
Spacemacs comes with a special ~lisp-state~ for working with lisp code that
supports slurpage, barfage and more tools you'll likely want when working with
lisp.

As this state works the same for all files, the documentation is in global
[[https://github.com/syl20bnr/spacemacs/blob/master/doc/DOCUMENTATION.org#lisp-key-bindings][DOCUMENTATION.org]]. In general, use ~SPC k~ to interact with the lisp-state.
