add callback to websocket-setup-env

[piranha]

As mentioned in #63, I need to be able to determine a port where weasel is listening in order to connect there. What do you think of this approach?

[tomjakubowski]

Nice! I didn't know http-kit supported running on an arbitrary available port. That's good to know about.

LGTM, but I'd prefer to name it something better than init. If we (or someone) can't come up a better one I'll happily merge though.

[piranha]

Yeah, init was a fast one and I don't like it either. It was a callback initially, which also doesn't convey a lot of information. How about connection-hook?

[tomjakubowski]

Since the callback is called before the connection is accepted what do you think of pre-connect? It has a nice symmetry with on-connect et al. in the client.

[piranha]

I like that! Changed. :)

[tomjakubowski]

Thanks so much!

Tom, can you please make a release? :-) I really want to stop supporting my own forks of weasel and boot-cljs-repl, and if you release weasel, boot-cljs-repl can be fixed for everyone. :)

[martinklepsch]

That sounds great, fixing boot-cljs-repl as well has been long outstanding. :)

[tomjakubowski]

Will release 0.7.0 after work today.

[tomjakubowski]

0.7.0 is released. Thanks for reminding me.

[piranha]

Thanks! :)

Hi @piranha , I have one strange problem, when client connected ,the console will be blocked . The cursor can move , but can never evaluate forms any more.

user=> (require 'weasel.repl.websocket)
nil
user=> (cemerick.piggieback/cljs-repl
  #_=>         (weasel.repl.websocket/repl-env :ip "0.0.0.0" :port 9001))
<< started Weasel server on ws://0.0.0.0:9001 >>
<< waiting for client to connect ...  connected! >>

version is below

[weasel "0.7.0" :exclusions [org.clojure/clojurescript]]
