Doumi.Port - A helper library that facilitates the usage of Python in Elixir

I will test it as soon as possible!

I recommend you to link to the Doumi.Port repository and the Hex package in the post. It will be easier for the people to check them .

Oh, I forgot it. Thanks!!

Nice, I might use it soon too…

I use poolboy with erlport, but I see You use nimble_pool instead

v0.2.0 is released!

use macro is added to make it easier.

defmodule MyApp.PythonPool do
  use Doumi.Port.Pool,
    port: {Doumi.Port.Python, python_path: [...]}
end

defmodule MyApp.Application do
  ...

  @impl true
  def start(_type, _args) do
    children = [
      ...
      MyApp.PythonPool
    ]

    Supervisor.start_link(children, strategy: :one_for_one, name: MyApp.Supervisor)
  end
end

defmodule MyApp.Native do
  def add(a, b) do
    MyApp.PythonPool.command(:operator, :add, [a, b])
  end
end

v0.4.0 is released!

• It supports Ruby also.
• mix doumi.port.init, mix doumi.port.setup is added.

# Create requirements.txt, .gitignores to ./priv/python

mix doumi.port.init --port python

# Add Python dependency

echo "pypdf2==3.0.1" >> ./priv/python/requirements.txt

# Install Python dependecies

mix doumi.port.setup --port python

You can install Python dependencies to your release with mix doumi.port.setup.

defmodule MyApp.MixProject do
  defp aliases do
    [
      ...,
      "release.setup": ["doumi.port.setup --port python", ...]
    ]
  end
end

...

# release setup (ex. install Python dependencies, compile assets)
RUN mix release.setup

...
