Top Top Program Structure
Common Lisp is a huge language, and Common Lisp systems tend to be massive and extremely complex. Emacs Lisp, by contrast, is rather minimalist in the choice of Lisp features it offers the programmer. As Emacs Lisp programmers have grown in number, and the applications they write have grown more ambitious, it has become clear that Emacs Lisp could benefit from many of the conveniences of Common Lisp.
The CL package adds a number of Common Lisp functions and control structures to Emacs Lisp. While not a 100% complete implementation of Common Lisp, CL adds enough functionality to make Emacs Lisp programming significantly more convenient.
Some Common Lisp features have been omitted from this package for various reasons:
assocfunction is incompatible with the Common Lisp
assoc. In such cases, this package usually adds the suffix `
*' to the function name of the Common Lisp version of the function (e.g.,
The package described here was written by Dave Gillespie,
firstname.lastname@example.org'. It is a total rewrite of the original
cl.el' package by Cesar Quiroz. Most features of the
the Quiroz package have been retained; any incompatibilities are
noted in the descriptions below. Care has been taken in this
version to ensure that each function is defined efficiently,
concisely, and with minimal impact on the rest of the Emacs
