muting specific warnings with the cljs compiler

[Chris Zheng]

I'm trying to figure out how to best deal with an issue on the newer versions of the class compiler:

https://github.com/purnam/purnam/issues/8

I've reproduced the issue causing the warning in this particular piece of code

(ns compiler.issue-1
(:require [purnam.test])
(:use-macros [purnam.core :only [? !]]))

(set! js/aa #js {})
(def a js/aa)
(! a.b.c 5555)
(+ 2 (? a.b.c) 3)


-----

Running the compiler with clojurescript "0.0-2411" yields a particular warning:

WARNING: cljs.core/+, all arguments must be numbers, got [number #{nil clj-nil}] instead. at line 9 test/cljs/compiler/issue_1.cljs

the previous versions of clojurescript do not give this warning. I'm hoping to get a bit of help/advice on how to deal with this.

you can get the warnings by:

git clone https://github.com/purnam/purnam.git
cd purnam
git checkout compilation-error
lein cljsbuild once

You may be hitting CLJS-907 (cf CLJS-917), fixed in 0.0-2629 and later.

Oh that’s brilliant!

Though I’m still wondering if there a way to turn off specific warnings (for future reference)
