Deterministic macro expansion for Clojure?
Hi all, I wonder if there is any way to make macro expansion in Clojure deterministic. That would be useful in unit tests. Something like this: ``` (defmacro lol [] `(let [a# 1] (inc a#))) (with-predictable-gensym-starting-from-zero (macroexpand '(lol)) ;; => `(let [a0 1] (inc a0)) ``` -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Joplin: No method in multimethod 'migrate-db' for dispatch value: :sql
joplin.jdbc.database works fine. Thanks for the tip.

Re: Deterministic macro expansion for Clojure?
Well, I think it's nondeterministic by design, we usually just test its behavior, not the form it expanded to. 2015-03-23 10:52 GMT+08:00 myguidingstar : > Hi all, > I wonder if there is any way to make macro expansion in Clojure > deterministic.
