It seems that the both IP and port number are hard-coded in lib/plug_session_memcached.ex. Do you have any plan you allow to configure them through a configuration like following?

plug Plug.Session,
  store: :memcached,
  host: "memcached.example.jp",
  port: 11211

When I download your package (from Github or Hex), I can download only plug_session_memcached.ex file.

Your package has plug_session_memcached.ex and plug_session_MEMCACHED.ex, but file system of Mac OS X is case insensitive.

So I think one of your file is overwritten by another one when downloaded.

Incidentally, when I download your package on Amazon Linux, I can get both plug_session_memcached.ex and plug_session_MEMCACHED.ex.

I think you should use different file name.

I am trying to integrate memcached in my project. However, I get the following error:

Looking up alternatives for conflicting requirements on plug
From mix.lock: 1.0.3

Here is my mix.exs:

I configured the plug as in the instructions. However, when I start my Phoenix server ("mix phoenix.server"), I receive the following error:

They are giving me dependency hell. Why is there a markdown parser in a memcache session plug anyway?

a release version, built with mix release doesn't work due to a crush.

You can reproduce the issue in these ways:

• mix phoenix.new memcached_test --no-brunch --database mysql
• adds plug_session_memcached, mcd, exrm into mix.exs
• build a release
  • MIX_ENV=prod mix do deps.get, compile
  • MIX_ENV=prod mix release
• rel/memcached_test/bin/memcached_test console
  • it crushes!

The test project is here: https://github.com/hykw/phoenix-test-memcached

The messages are following(Also, I attach erl_crash.dump, just in case)

$ MIX_ENV=prod mix release
Building release with MIX_ENV=prod.

You have dependencies (direct/transitive) which are not in :applications!
The following apps should to be added to :applications in mix.exs:

        lager => lager is missing from memcached_test

Continue anyway? Your release may not work as expected if these dependencies are required! [Yn]:

==> The release for memcached_test-0.0.1 is ready!
==> You can boot a console running your release with `$ rel/memcached_test/bin/memcached_test console`

on linux in my deps lib dir I get:

-rw-rw-r-- 1 crispin crispin 2116 Jul 6 16:50 plug_session_MEMCACHED.ex

but on mac OSX one file blats the other and the plugin doesn't work.

-rw-rw-r-- 1 crispin crispin 2116 Jul 6 16:53 plug_session_MEMCACHED.ex

I noticed you have merged the two files into one now.

Can you please tag and release a new version of this so it can work on macs?
