pythra

pythra translates the erlport wrapper parts of lfex/py to erlang

I did this mainly to make it easy to work with python objects and methods.

Python3 only.

Requirements

+ erlang >= 17
+ python 3
+ the python lib cytoolz

Build

$ rebar3 compile

Use

# start
$ rebar3 shell

Example

erlang

Object instantiation and method call

1> {ok, P} = pythra:start_link().            
{ok,<0.156.0>}
2> Obj = pythra:init(P, 'user.pyclass', 'Pyclass', [7]).
pyClass __init__
{'$erlport.opaque',python,
                   <<128,2,99,117,115,101,114,46,112,121,99,108,97,115,115,
                     10,80,121,99,108,97,115,115,10,113,0,...>>}
3> pythra:method(P, Obj, get_value).               
7
4> pythra:stop(P).

python

class Pyclass:

    def __init__(self, value):
        print("pyClass __init__")
        self.value = value

    def get_value(self):
        return self.value
