Re: Macro tutorials?

Hi, Nicolas, and thanks. I'm new to clojure (I've been working through Programming Clojure), and most of my long work life has gravitated around c, shell scripts, and perl. That being said, I've tinkered with Lisp dialects for the past twenty-five years (mostly elisp, scheme, and common lisp),

Re: Macro tutorials?

Hi. You might consider reading Peter Seibel's excellent Practical Common Lisp which has some nice macro-work in it. If after that you're still hungry for more, consider Let Over Lambda by Doug Hoyte. Admitted, both cover Common Lisp, but the differences will not keep you from getting a

Macro tutorials?

Hi! I wrote few apps with clojure. I have used many times macro to expand expressions and change some control flows. I thought that I know macros, but now I know that doing some programming by analogy is not enough. In fact I still don't know the macros works, I don't know when and how is

Re: Macro tutorials?

I have manage to write something like this. But nothing more, all my ideas are wrong, because bad knowledge about evaluation and namespace expansion time. (defmacro map-fnc [ methods ] `(reduce (fn[ acc# m# ] (assoc acc# (str (first m#)) (list 'fn (rest m#)) )) {} '~methods ))

And just for fun some more: (defmacro map-fn [ fns] (into {} (map (fn [[n tail]] [(keyword n) `(fn ~@tail)]) fns))) -- You received this message because you are subscribed to the Google Groups Clojure group. To post to this group, send email to clojure@googlegroups.com Note that posts from
