Hi,
I'm working on some tools for making it easier to share generic Clojure
code between Clojure and ClojureScript, and one problem that does not seem
to have a pretty solution is that of requiring macros. Clojure uses a
regular (:require ...) whereas ClojureScript needs a (:require-macros ...).
I understand that the distinction is necessary for ClojureScript because
macros are written in Clojure.
This difference in the (ns ...) form is troublesome when trying to share
code between the two languages. Right now, the only solution is to
copy+edit the shared file (possibly with an automated tool) so that it has
:require and :require-macros as appropriate. This is not very pretty.
So that gets me to wondering, has anyone brought up the idea of using
metadata to identify macro namespaces? So instead of using
:require-macros, :require would be used, but each namespace identifier
would be inspected to see if it had ^{:macros true}.
; The existing way to require macros from ClojureScript:
(ns example.shared
(:require-macros
[example.macros :as macros])
(:require
[example.other :as other]))
(ns example.shared
(:require
^:macros [example.macros :as macros]
[example.other :as other]))
