The complete text of Let Over Lambda, a seminal 2008 book by Doug Hoyte on Common Lisp macros, has been made freely available online in HTML and PDF formats. Published to coincide with Lisp's 50th anniversary, the book explores advanced macro techniques as core to the language's expressive power. The author notes that while some perspectives have evolved since publication, the material remains a relevant tutorial on why Lisp stands out.
Background
Common Lisp is a member of the Lisp family known for powerful macro systems that allow code to generate code, enabling high-level abstraction. The book Let Over Lambda is widely regarded as one of the most thorough and challenging resources dedicated exclusively to mastering these macro techniques.
