Here's an example: (defmacro foo [x] `(list ~x ~x)) (defmacro bar [x] `[~x ~x]) Now let's work on the form (foo (bar 'baz)) Plain macroexpand returns (list (bar 'baz) (bar 'baz)) whereas tools.macro/mexpand-all gives (list ['baz 'baz] ['baz 'baz]) It does this by first calling macroexpand, so foo gets called exactly as during Clojure compilation and returns (list (bar 'baz) (bar 'baz)) mexpand-all then goes through that form and expands the two subforms (bar 'baz). So mexpand-all does exactly what the compiler does, in particular it calls the macros with exactly the same arguments. But the compiler interleaves macro expansion with compilation, so it never gives you access to the fully expanded but uncompiled form which is (list ['baz 'baz] ['baz 'baz]) Konrad -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
