dry / elixir-cowboy-example Goto Github PK

Looks like this may have been written pre-Hex. Currently, cowboy is a few versions newer and lager is not in the Hex database. In elixir 0.14, cowboy doesn't compile with this version of the code.

I attempted to update the dependencies (in mix.exs) to current versions pulled from github, which worked, both deps compiled, as follows:

defp deps do
  [ { :cowboy, github: "extend/cowboy", tag: "0.10.0" },
    { :lager, github: "basho/lager", tag: '2.0.3' } ]
end

However, once compiled, the example code then fails to run, with the following message:

[22:04:11 elixir-cowboy-example (master)]$ mix compile
==> lager (compile)
Compiled src/lager_app.erl
Compiled src/lager.erl
Compiled src/lager_file_backend.erl

== Compilation error on file lib/lager.ex ==
** (CompileError) lib/lager.ex:4: undefined function lc/2
    (elixir) src/elixir.erl:195: :elixir.quoted_to_erl/3
    (stdlib) erl_eval.erl:657: :erl_eval.do_apply/6
    (elixir) src/elixir.erl:163: :elixir.erl_eval/2

As yet i'm too much of an elixir noob (started just 4 days ago) to debug that on my own. If I do manage to fix it, however, I'll issue an pull request. In the meantime, any advice is appreciated!
