Reader Macros in Common Lisp

Reader Macros in Common Lisp

This post also appears on

Reader macros are perhaps not as famous as ordinary macros. While macros are a great way to create your own DSL, reader macros provide even greater flexibility by allowing you to create entirely new syntax on top of Lisp.

Paul Graham explains them very well in [On Lisp][] (Chapter 17, Read-Macros):

The three big moments in a Lisp expression's life are read-time, compile-time, and runtime. Functions are in control at runtime. Macros give us a chance to perform transformations on programs at compile-time. do their work at read-time.

Efficiency and Orders of Growth

Efficiency and Orders of Growth

Measuring complexity:

  • time
  • memory

Mesuring base steps

  • use a random access machine as model of computation
  • steps are executed sequentially
