shadow-build is fine with that, expects it in fact. Not really sure why cljs 
allows multiple :entries per :module but :main only allows one. In shadow-build 
everything is built with regards to modules, eg. the typical build with one 
output-file is just a build with one module. How many you add after that is up 
to you. So all options that apply to modules always apply, there is no seperate 
path for modules/non-modules.

Makes things far easier to reason about IMHO.

YMMV,

An enhancement patch to make :modules work with :none is welcome.

Great! I will work on that.

@Thomas: Thanks, I will have a look at shadow-build

Re: [ClojureScript] google closure modules and the :main compiler option

Would you also consider a patch to make the :main option to accept a collection 
of namespaces? When optimizations are enabled, the closure compiler may 
concatenate multiple namespaces, thus I think this change would make sense.

Also, don't you think the browser repl environment should be given the 
possibility to output a main js file at startup? This file could contain a call 
to clojure.browser.repl/connect, making the browser repl simpler to start.

Not interested in :main taking a collection of namespaces. The browser REPL
issue is broader, needs more consideration, and even has an existing JIRA
issue.

[ClojureScript] google closure modules and the :main compiler option

[ewen]

Hi,

The :main option of the ClojureScript compiler is very useful to be able to 
leave HTML markup identical between dev and production. However, its purpose is 
defeated when using google closure modules because it can only output one file 
and require one namespace.

A possible solution would be to allow :optimzations :none when :modules are 
enabled. The compiler would emit multiple main files, each requiring the 
namespaces it depends on.

Any thoughts on this?

Ewen.
