Customising symbol resolution with defn style

[pbzdyl]

Currently custom symbol resolution supports following styles: def, let, for, -> and ->>.

It would be useful to also support defn style. It would work in cases like defcommand for Hystrix. Currently function (Hystrix command) arguments are not resolved and are shown as unresolved symbols in the args vector and function body.

Example Hystrix function/command:

(defcommand shorten-url
  {:hystrix/command-key "ShortenUrl"
   :hystrix/group-key GoogleApi}
  [long-url api-key]
  (println long-url api-key))

  I was just about to ask for the same feature...

+1 "Works like defn" is a very common macro pattern. I currently set these to "works like def" but the locals they define in the vector are still unresolved.

Interestingly, I was able to edit the config file where these are stored (IDEA_CONFIG_DIR/config/options/ClojureResolveSettings.xml) and change resolve-as to clojure.core/if-let, clojure.core/when-let, (I have two macros with the same shape as if-let and when-let) and clojure.core/defn and Cursive appears to understand correctly the binding and scope of the local vars my macros create.

I'll add defn to the list of options.

@favila, yes, you can hack your config file as you've discovered, and it will work as you expect in the meantime.

@favila One thing to note with that hack - if you fiddle with that file and add a modification which requires indexing more vars (i.e. not just local bindings), you’ll need to do a File->Invalidate Caches.
