Standalone Web UI doesn't start

[romul]

Hi, I managed start exq itself and it works great.
But web UI refuses to start with an error:

$ mix exq.ui --webport 4040

Started ExqUI on Port 4040
** (UndefinedFunctionError) undefined function: Exq.RouterPlug.init/1 (module Exq.RouterPlug is not available)
    Exq.RouterPlug.init([namespace: "", exqopts: [name: :exq_enq_ui, host: '127.0.0.1', webport: 4040]])
    lib/plug/adapters/cowboy.ex:155: Plug.Adapters.Cowboy.dispatch_for/2
    lib/plug/adapters/cowboy.ex:36: Plug.Adapters.Cowboy.args/4
    lib/plug/adapters/cowboy.ex:126: Plug.Adapters.Cowboy.run/4
    lib/mix/tasks/exq.ui.ex:22: Mix.Tasks.Exq.Ui.run/1
    (mix) lib/mix/cli.ex:55: Mix.CLI.run_task/2

Could you point me what is going wrong?

Ok, that's because of a hex package doesn't contain web directory.
Web UI works if github link is used as dependency:

  defp deps do
    [
      {:exq, github: 'akira/exq'}
    ]
  end

[romul]

Although some strange errors still occur in the console log:

21:20:52.333 [error] Ranch listener Exq.RouterPlug.HTTP had connection process started with :cowboy_protocol:start_link/4 at #PID<0.429.0>

I'll try to take a look today.

[mspanc]

I have the same issue

[j-mcnally]

Thanks so much for the report. I will get this fixed in master tonight. I think the problem is I haven't kept up with testing new elixirs and otps

[akira]

@j-mcnally great, let me know if you need any help (btw, you should have commit access to master).

[j-mcnally]

ok so just to keep everyone updated, i pulled master and was able to run
mix exq.ui --webport 4040

and everything works.

Im going to create a dummy project and try to reproduce the issue.

@mspanc or @romul would it be possible to get a simple project where this fails.

As for the hex package missing the web directory i must admit i don't know much about hex packages.

@akira do you have any idea why that would be the case?

[j-mcnally]

ok i was able to reproduce with

defmodule ExqTest.Mixfile do
  use Mix.Project

  def project do
    [ app: :exqtest,
      version: "0.0.1",
      elixir: "~> 1.0.0",
      elixirc_paths: ["lib"],
      package: [],
      description: """
      Exq test.
      """,
      deps: deps ]
  end

  # Configuration for the OTP application
  def application do
    [
      mod: { ExqTest, [] },
      applications: [:logger]
    ]
  end

  # Returns the list of dependencies in the format:
  # { :foobar, "0.1", git: "https://github.com/elixir-lang/foobar.git" }
  defp deps do
    [
      {:exq, path: '../exq'}
    ]
  end
end

[j-mcnally]

@romul's fix works perfect. Must be a new plug thing. Still perplexed why it works in isolation but not when embeded in another project. O well.

Now we just need to fix the hex package and we should be good to go.

[j-mcnally]

@mspanc do you mind testing with master.

Basically just swap out the hex package for {:exq, github: 'akira/exq'} as @romul suggests.

[akira]

@j-mcnally I'll take a look at the hex package issue

[akira]

@j-mcnally I added to it to the files in mix.exs and bump / published it again. It should work now, let me know if not or if there are any other issues.
