Newer elixir versions

[Linuus]

The readme says that Scenic only works with Elixir 1.7 and OTP 21.

I can’t find any issues here on github on what’s not working on later versions. Is there such a list somewhere?

I just installed scenic and generated a nerves app. Now I get this warning: warning: the dependency :scenic requires Elixir "~> 1.8" but you are running on v1.7.4. So I guess the Readme here is wrong then?

@Linuus If we take a look at mix.exs in scenic repository then we would find:

defmodule Scenic.Mixfile do
  # …

  @elixir_version "~> 1.8"
  # …

  def project do
    [
      # …
      elixir: @elixir_version,
      # …
    ]
  end
  # …
end

Which means that scenic requires elixir in at least 1.8 version.

Then we can take a look at history of that file. and finally we would see:

…

back to 1.8
boydm committed on 10 Mar

turn off build_embedded
boydm committed on 10 Mar

try building under 1.7
boydm committed on 10 Mar

so to elixir 1.8
boydm committed on 10 Mar…

…

Which gives as a hint that scenic not longer compiles under elixir in version 1.7. Most probably it uses some new elixir API or there were a bug in elixir fixed in version 1.8.

Looks like that scenic would require elixir in version 1.8 and it won't be changed.

@boydm Looks like we would need to update some parts of code (like templates in examples) + documentation.

Of course... I don't exactly remember what the reason for going to 1.8 was...

Cool :)

Just to be clear, this is the part that confused me: https://github.com/boydm/scenic_new/blob/master/README.md#erlangelixir-versions
