Demonstrates a bug in ClojureScript/cljsbuild's implementation of goog-define plus :closure-defines override.
The source is just a trivial piece of ClojureScript that logs a message containing a goog-defined var.
Four build profiles are defined, one for each optimization type, and each sets that var to the name of the optimization type. For :none and :whitespace optimizations, the goog-define mechanism doesn't appear to work. For :none, adding a :main entrypoint to the compiler options seems to fix the issue, but not for :whitespace.
So far, tested with CLJS 1.7.122 and cljsbuild 1.0.6.
lein cljsbuild once none whitespace simple advanced
open resources/public/index.htmlOpen the JS console. On the main page you should see three messages. Expected:
optimization type is whitespace
optimization type is simple
optimization type is advanced
Actual:
optimization type is opt-type define not set
optimization type is simple
optimization type is advanced
Likewise, the sub-page for "none" optimization also gives "not set" instead of "none" if the :main option is not set in the cljsbuild options.
