Usage Overview Installation
The Common Lisp package is organized into four files:
This is the ``main'' file, which contains basic functions and information about the package. This file is relatively compact---about 700 lines.
This file contains the larger, more complex or unusual functions.
It is kept separate so that packages which only want to use Common
Lisp fundamentals like the
This file contains most of the advanced functions for operating
on sequences or lists, such as
This file contains the features of the packages which are macros
instead of functions. Macros expand when the caller is compiled,
not when it is run, so the macros generally only need to be
present when the byte-compiler is running (or when the macros are
used in uncompiled code such as a `
The file `
cl.el' includes all necessary
commands for the functions and macros in the other three files.
All you have to do is
(require 'cl), and `
will take care of pulling in the other files when they are
There is another file, `
cl-compat.el', which defines some
routines from the older `
cl.el' package that are no longer
present in the new package. This includes internal routines
zip-lists, deprecated features
defkeyword, and an emulation of the old-style
multiple-values feature. See Old CL Compatibility.
