We describe ESA (for Emacs-Style Application), a library for writing applications with an Emacs look-and-feel within the Common Lisp Interface Manager. The ESA library takes advantage of the layered design of CLIM to provide a command loop that uses Emacs-style multi-keystroke command invocation. ESA supplies other functionality for writing such applications such as a minibuffer for invoking extended commands and for supplying command arguments, Emacs-style keyboard macros and numeric arguments, file and buffer management, and more. ESA is currently used in two major CLIM applications: the Climacs text editor (and the Drei text gadget integrated with the McCLIM implementation), and the Gsharp score editor. This paper describes the features provided by ESA, gives some detail about their implementation, and suggests avenues for further work.
