Thank you. Wrote a line in that format calling another function called rar_extraction. Here’s the total code I have so far
defmodule RarFile do
archive_path = 'extractor/Kickassv301.cbr'
destination_folder = 'extractor/extracted'
def extractor(filepath) do
{:ok, pi1} = :python.start()
:python.call(pid1, :handler, :rar_extraction, [archive_path, destination_folder])
end
end
However,I get a error from the ninth line that says
(CompileError) undefined function archive_path/0 (expected RarFile to define such a function or for it to be
imported, but none are available)
What could be causing this?

Move the variables inside the function.
Or if you want them to be accessible for the entire module, make them module attributes.

No need to use charlist here, You can use binaries…
But it is only half of the problem, because the Python part is tricky to setup. You’ll need to do some conversion of data in the Python script. Something like this…
if isinstance(path, bytes):
path = path.decode("utf-8")
if not os.path.exists(path):
return ("error", "path does not exists.")
else:
return ("error", "cannot decode path.")

Hi, I’ve just released Doumi.Port - A helper library that facilitates the usage of Python in Elixir.
This library will make it much easier to use Python in Elixir.
Thanks!
