Common Lisp Extensions

1 Introduction

This document describes a set of Emacs Lisp facilities borrowed from Common Lisp. All the facilities are described here in detail. While this document does not assume any prior knowledge of Common Lisp, it does assume a basic familiarity with Emacs Lisp.

• Overview: Installation, usage, etc.
• Program Structure: Arglists, `eval-when', `defalias'
• Predicates: `typep', `eql', and `equalp'
• Control Structure: `setf', `do', `loop', etc.
• Macros: Destructuring, `define-compiler-macro'
• Declarations: `proclaim', `declare', etc.
• Symbols: Property lists, `gensym'
• Numbers: Predicates, functions, random numbers
• Sequences: Mapping, functions, searching, sorting
• Lists: `cadr', `sublis', `member*', `assoc*', etc.
• Structures: `defstruct'
• Assertions: `check-type', `assert', `ignore-errors'.
• Efficiency Concerns: Hints and techniques
• Common Lisp Compatibility: All known differences with Steele
• Old CL Compatibility: All known differences with old cl.el
• Porting Common Lisp: Hints for porting Common Lisp code
• GNU Free Documentation License: The license for this documentation.
• Function Index
• Variable Index
