The Common Lisp Cookbook – Editor support

The editor of choice is still Emacs, but it is not the only one.

Emacs

SLIME is the Superior Lisp Interaction Mode for Emacs. It has support for interacting with a running Common Lisp process for compilation, debugging, documentation lookup, and so on.

Portacle is a portable and multiplatform Common Lisp environment. It ships Emacs25, SBCL, Quicklisp, Slime and Git.

Using Emacs as an IDE

See “Using Emacs as an IDE”.

Setting up Emacs on Windows or Mac

See “Setting up Emacs on Windows or Mac”.

Vim

Slimv is a full-blown environment for Common Lisp inside of Vim.

Vlime is a Common Lisp dev environment for Vim (and Neovim), similar to SLIME for Emacs and SLIMV for Vim.

Atom

See Atom-Slime. This package allows you to interactively develop Common Lisp code, helping turn Atom into a full-featured Lisp IDE.
