Using emacs daily, pretty much whole day, since about late 1998. Learning & coding elisp on and off seriously, since 2006. Written many text processing scripts, a major mode, and written a book on emacs and elisp.

• Emacs xlsl-mode for Linden Scripting Language

• Xah's Emacs Tutorial

I am a emacs expert. I'm also a elisp expert in the context of programing industry. But when compared to dedicated emacs developers, i'm rather a beginner. For example, some corners of elisp i still don't understand quite well: its display mechanism, faces, overlay, windows and frames, key mapping and events complexities.

you have also lots of one-sentence questions. You will find some answers here:


which is a index page of collection of essays related to emacs. About 15 of them, are related to lisp in general. Each page usually has “Related Essays” links at the bottom that takes you to other essays on the topic, giving you more detail, or covering other aspects.

I recommend to start with the following, more quality ones:

• Fundamental Problems of Lisp

• The Concepts and Confusions of Prefix, Infix, Postfix and Fully Nested Notations

• What are OOP's Jargons and Complexities
