Call Python functions from Elixir.

(Coming soon) If available in Hex, the package can be installed by adding python_ex to your list of dependencies, and optionally :pip_deps to the tail of the list of compilers in mix.exs:

def deps do
  [
    {:python_ex, "~> 0.1.0"}
  ]
end

# Set up a python venv
{:ok, python_path} = Python.install_venv(venv_path, "python3")
# Install packages via pip
:ok = Python.install_pip_pckgs(python_path, ["numpy"])
# Start the server.
{:ok, pid} = Python.Server.start_link(venv_dir: "venv")

my_python_package = :code.priv_dir(:my_app) |> to_string()

# Call the Python function `my_python_module.my_echo_fun("hello")`
Python.apply(my_python_package, :my_python_module, :my_echo_fun, "hello")
# => "hello"

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/python_ex.

Use Python.apply(module_directory, :module_name, :function_name, arg) to call a Python function with a single binary argument.

• The module directory is recommended to be the priv folder.
• The module name is in the format of an import statement, eg. :"mypackage.mymodule".
• The function is called with a single binary/bytes argument,
• and the Python function is expected to return a bytes/binary value.
