Python-Ernie

By Ken Robertson (ken@invalidlogic.com)

Python-Ernie is a port of the Ruby-based Ernie server by Tom Preston-Werner. Python-Ernie is the Python server implementation for the BER-RPC specification.

See the full BERT-RPC specification at bert-rpc.org.

Installation

To install Python-Ernie, you can use pip or traditional setup.py:

$ pip install git+git://github.com/krobertson/python-ernie

pip will install all the dependencies for you which you have to do by yourself when using setup.py directly. This means you need to install the Python port of BERT serializers and Erlastic.

$ git clone git://github.com/samuel/python-erlastic.git
$ sudo python python-erlastic/setup.py install

$ git clone git://github.com/samuel/python-bert.git
$ sudo python python-bert/setup.py install

To install python-ernie itself, run:

$ sudo ./setup.py install

Example Handler

from ernie import mod, start

from ernie import mod, start

def calc_add(a, b):
    return a + b
mod('calc').fun('add', calc_add)

if __name__ == "__main__":
    start()

Contribute

If you'd like to hack on Python-Ernie, start by forking my repo on GitHub:

http://github.com/krobertson/python-ernie

Just create your own fork, hack on it, and then send me a pull request once done.

Todo

I'll be the first to admin I am still new to Python. So if I am way off on best practices in Python, let me know!

  1. Update exception handling to return traceback
  2. Ensure correct handling around read operations
  3. See if I can clean up the way you define your modules
  4. Test
