Pyrlang - Erlang node in Python

Section titled “Pyrlang - Erlang node in Python”

This is a drop-in Erlang node implementation in Python 3, implementing a network Erlang node protocol. It was designed to allow interoperation between existing Python projects and BEAM languages: Erlang, Elixir, Gleam, Luaerl, LFE, Clojerl and such.

With just a few lines of startup code your Python program becomes an Erlang network node, participating in the Erlang cluster.

Features

Section titled “Features”
  • Erlang distribution protocol for Erlang versions 19 to 25
  • Registry of Python ‘processes’, which have an Erlang-compatible process identifier and an optional registered name
  • Send and receive messages locally and remotely by pid or name
  • Can link and monitor Erlang from Python and Python from Erlang
  • net_adm pings supported
  • RPC calls to Python (Erlang rpc:call). Exceptions are propagated from Python back to Erlang;
  • pyrlang.gen.server.GenServer descendant from pyrlang.process.Process allows accepting generic calls mapped to Python class members
