Gödel, Escher, Elisp: The Beauty of Macros
Summary
A deep dive into Emacs Lisp macros, exploring homoiconicity, macro expansion, and meta-programming with code-as-data. The article uses Hofstadter and Escher analogies to illuminate how macros rewrite code, showcases practical examples (defun, use-package, deftoggle), and discusses tooling for introspection and debugging. It ends with guidance on when to use macros and cautions about complexity.
