hot code reload in erlang shell like what i use in python development server

 use rebar all the time. In rebar.config, I have

 {deps,[
        {sync, ".*", {git, "git://github.com/rustyio/sync", {tag,"master"}}},
 }

for relang.mk just add sync to deps

 use a .erlang file, typically placed in src/.erlang with the following two lines

 code:add_path("../deps/sync/ebin").
 sync:go().

Now, whenever I save a file, it is reloaded. I see no reason why this shouldn't work for Cowboy
