Parsing is done using a per character tokenizer. Two stacks are used to simulate a recursive parse.

<Tab> indents lines (or ranges in visual mode)
<C-\> indents the toplevel form. Or whatever is at 150[(.

To indent an entire file, do 1GVG<Tab>. This may take a while for a large file.

:CLLoadLispwords refreshes the lisp word file
:CLIndentForm indents the toplevel form
:CLIndentRange indents a range
:CLIndentLine indents a line
:CLSetWord <word> <number> sets a lispword

Customizable variables:
String :: g:CL_lispwords_file defaults to ~/lispwords.
Boolean :: g:CL_aggressive_literals defaults to 1
Boolean :: g:CL_retab_on_open defaults to 1
Integer :: g:CL_auto_zero_limit defaults to 25
List <String> :: g:CL_loop_keywords lists all known loop keywords
List <String> :: g:CL_flets lists forms to be handled similar to flet
List < List < String, Integer > > :: g:CL_auto_prefixes lists all regexp base lisp numbers.

Add <<let g:VARIABLE = VALUE >> to your ~/.vimrc to change this. For Boolean variables, 1 is true and 0 is false.

Lisp words are stored 1 per line as such:
<symbol> <lisp #>

Aggressive literals means that forms such as (:hello world), ('got milk) and (&optional var1 var2) are treated as literals. The first character of the first symbol (if it is a symbol) are tested to match [&':].

While indenting, auto prefixes iterates over each string-integer pair. If the string matches the parent (for example "def" matches "defclass", and "^[abc].*$" matches "chair"), then the associated lisp word number is used for indentation. The first match wins.
I default to: [["with-",1], ["def",2], ["make-",1], ["map",1]]

Auto zero limit was added to preserve screen real estate for long lispy symbol names. If a symbol in your program looks like "variable-that-holds-an-integer-and-is-used-for-counting", you may appreciate this setting. Any parent string longer than the limit will be handled as a lisp number zero. By default, this is 25 characters.

My lispwords file is available at: http://paste.lisp.org/display/97882
It is not complete, but might be a useful starting point.

The indentation behavior was based on a description at http://evalwhen.com/scmindent/index.html.
install details
Save to ~/.vim/ftplugins/lisp.vim, or configure a custom command in your .vimrc such as:
autocommand! BufRead *.lisp source <file_location>

Provide an empty lispwords file, or you will see an error on the first run.

lisp.vim 2.0 2010-04-16 6.0 Eric O'Connor Minor change - break the auto prefix loop correctly.
lisp.vim 1.9 2010-04-16 6.0 Eric O'Connor Bug fixes, and prefix based form handling.
lisp.vim 1.8 2010-03-18 6.0 Eric O'Connor Proper comment handling. Added g:CL_define_keywords to handle multi-line variable lists.
lisp.vim 1.7 2010-02-06 6.0 Eric O'Connor Macrolets, flets, labels.
lisp.vim 1.6 2010-02-06 6.0 Eric O'Connor Loop form handling.
lisp.vim 1.5 2010-02-06 6.0 Eric O'Connor + Simple vector's gave parentheses error because they weren't handled within the sharp-sign state
+ Screen stability bugs
+ Improved plug-in hygiene (b:undo_ftplugin)
+ Added an option [g:CL_aggressive_literals] to detect all forms beginning in [&:'].* as literals. Default: true
+ Default re-tabs a new lisp file. Turn off with g:CL_retab_on_open = 0
+ Changed the g:lispwords_file variable to g:CL_lispwords_file to avoid confusion.
+ Removed unused code
lisp.vim 1.4 2010-02-03 6.0 Eric O'Connor More bug fixes regarding expandtab handling. It may be beneficial to issue :retab! if you transition from expanded tabs to hard tabs.
New lines are now auto indented properly.
lisp.vim 1.3 2010-02-01 6.0 Eric O'Connor Changed the algorithm slightly so it jives better with <noexpandtab>.
Minor bug fixes:
A multi-line s-exp or string on the first line of it's parent will now indent correctly.
lisp.vim 1.2 2010-02-01 6.0 Eric O'Connor Persistent lisp words - saves on quit.
<CLSetWord defun 2> sets a lisp word.
lisp.vim 1.1 2010-01-31 6.0 Eric O'Connor Oops! Sorry to the ... 8 people that have downloaded so far.
Fixed 2 bugs:
1. When reducing indentation, the script attempted to jump to a negative column, causing the cursor to jump.
2. With <noexpandtab>, the indentation counted tabs as a single space. Corrected by adding (&tabstop-1) * the number of leading tabs to the indentation

Let me know if you find anything else wrong with it: <oconnore@gmail.com>
