Hey,
not sure what you are trying to achieve, since the compiler should already warn
you if a var is not found. Might not do so when nesting defs. def/defn are top
level forms und should not be nested, especially no def in a defn.
As for your question: the CLJS compiler supports vars in
Thomas, this is an isolated test, the real case was creating a defmulti
macro wrapper and a defmethod one, so in the mydefmulti macro I attach some
metadata to the var defmulti defines and then I fetch it in the mydefmethod
calls (by using resolve), all in compile-time. This works perfectly in the
The key is in what you think you mean by 'available at compile-time'.
How could this be the case?
The macro system has no knowledge of the CLJS compiler internals, and the
CLJS compiler does not try to project its state onto the clojure namespace
system.
However, CLJ macros can return symbols
The other piece of the puzzle:
cljs.core/resolve-var is in a CLJ namespace and uses compiler state:

Why are you bringing the built-in macro env into this?
Cljs.core/resolve-var refers to this env:

AFAIK there is no link between them (I could be wrong).

We still have to consider that println won't work, even if it is possible
to resolve the var, so you'll have to use some other method to see the
data:

I'm writing a wrapper library on goog.net.Cookies and using clojurescript.test
for unit testing on Phantom. But I can't manipulate the cookies in the test.
It's saying:
```
Testing cljs-cookies.core-test
SECURITY_ERR: DOM Exception 18: An attempt was made to break through the
security policy
You already answered the println question, now I'm using spit inside the
macro instead of println, let's forget about it. Now the problem is to
access CLJS vars at compile time from the macro, not printing them :)
The issue seems to be reduced to the question if you can access the CLJS
compiler
