Clojure Macros Continue To Surprise Me Tonsky Me Clojure has a programmatic macro system which allows the compiler to be extended by user code. macros can be used to define syntactic constructs which would require primitives or built in support in other languages. many core constructs of clojure are not, in fact, primitives, but are normal macros. Thanks to nicola mometto, clojure core committer, for contributing this chapter (except “definline”). arguably one of the most powerful aspects of any lisp is their ability to define custom and arbitrarily complex macros, and clojure is no exception.
Clojure Macros Continue To Surprise Me Tonsky Me Macros are defined using the clojure.core defmacro function that takes macro name as a symbol, an optional documentation string, a vector of arguments and the macro body. With macros, you can extend clojure to suit your problem space, building up the language. in this chapter, you’ll thoroughly examine how to write macros, starting with basic examples and moving up in complexity. As with all lisps, clojure's inherent homoiconicity gives you access to the full extent of the language to write code generation routines called "macros". macros provide a powerful way to tailor the language to your needs. Using this macro as a basis i hope to walk through the entire process of creating a clojure macro from inception to implementation, and along the way cover everything that is required for you as a reader (and potentially being new to clojure) to create a non trivial macro of your own.

If you want to learn how to write clojure macros, i recommend reading the macros chapter of clojure for the brave and true. but for when you just want to remember the key parts of writing clojure macros, here’s a handy cheat sheet. In this sense, macros are like special functions for the reader, and clojure provides us with a special form for creating macros called defmacro. Clojure is no exception and provides simple macro facilities for developers. macros are used to write code generation routines, which provide the developer a powerful way to tailor the language to the needs of the developer. Explore the use of function wrapper macros in clojure to elegantly handle cross cutting concerns by creating reusable and maintainable function wrappers. this discussion includes example implementations, related design patterns, and additional resources.
