/**
|
|
* @fileoverview
|
|
* Registers a language handler for Common Lisp and related languages.
|
|
*
|
|
*
|
|
* To use, include prettify.js and this file in your HTML page.
|
|
* Then put your code in an HTML tag like
|
|
* <pre class="prettyprint lang-lisp">(my lisp code)</pre>
|
|
* The lang-cl class identifies the language as common lisp.
|
|
* This file supports the following language extensions:
|
|
* lang-cl - Common Lisp
|
|
* lang-el - Emacs Lisp
|
|
* lang-lisp - Lisp
|
|
* lang-scm - Scheme
|
|
* lang-lsp - FAT 8.3 filename version of lang-lisp.
|
|
*
|
|
*
|
|
* I used http://www.devincook.com/goldparser/doc/meta-language/grammar-LISP.htm
|
|
* as the basis, but added line comments that start with ; and changed the atom
|
|
* production to disallow unquoted semicolons.
|
|
*
|
|
* "Name" = 'LISP'
|
|
* "Author" = 'John McCarthy'
|
|
* "Version" = 'Minimal'
|
|
* "About" = 'LISP is an abstract language that organizes ALL'
|
|
* | 'data around "lists".'
|
|
*
|
|
* "Start Symbol" = [s-Expression]
|
|
*
|
|
* {Atom Char} = {Printable} - {Whitespace} - [()"\'']
|
|
*
|
|
* Atom = ( {Atom Char} | '\'{Printable} )+
|
|
*
|
|
* [s-Expression] ::= [Quote] Atom
|
|
* | [Quote] '(' [Series] ')'
|
|
* | [Quote] '(' [s-Expression] '.' [s-Expression] ')'
|
|
*
|
|
* [Series] ::= [s-Expression] [Series]
|
|
* |
|
|
*
|
|
* [Quote] ::= '' !Quote = do not evaluate
|
|
* |
|
|
*
|
|
*
|
|
* I used <a href="http://gigamonkeys.com/book/">Practical Common Lisp</a> as
|
|
* the basis for the reserved word list.
