Project description

# hermes

Hermes is an extensible XMPP-based chatroom server written in Python.
Easily setup and manage chatrooms for friends or colleagues.

## How it Works

Supply your own XMPP-based accounts (Google accounts work great!) to serve as chatroom hosts, add a bit of configuration, and that's it.
All chatroom members are invited to chat with the chatroom host which will in turn broadcast their messages to all other members.

## Usage

The "Hello World" usage of Hermes looks like this. Put the following in ``, update the user and chatroom info, and run it:

from hermes.api import run_server

brain = { 'JID': '', 'NICK': 'brain', 'ADMIN': True }
pinky = { 'JID': '', 'NICK': 'pinky' }

chatrooms = {
'world-domination-planning': {
'JID': '',
'PASSWORD': 'thesamethingwedoeverynight',
'SERVER': ('', 5223,),
'MEMBERS': [pinky, brain],


## Installation

Available from PyPI: <>. pip is the recommended installation method:

pip install hermes

## Commands

Hermes interprets some messages as commands:

* `/mute` - Mute the chatroom. Messages are queued up for whenever you unmute the chatroom.

* `/unmute` - Unmute the chatroom. Receive all messages that were queued while the chatroom was muted.

* `/invite <handle>` - Invite members to the chatroom. Available to admins only.

* `/kick <handle>` - Kick members from the chatroom. Available to admins only.

* `/marco` - Not sure if you're still connected to the chatroom? Chatroom replies to you (and only you) with "polo".

## Extensibility

You can extend the base chatroom class `hermes.Chatroom` to modify or add extra functionality.

Adding a `command_patterns` static property to your class should be particularly useful for extensions.
It's a list of regular expression/method name pairs. Each incoming message is tested against the regexes until a match is found.
On a match, the named instance method is invoked to handle the message instead of the default message-handling pipeline.

Specify the path to your creation as a string or the Class itself as the `CLASS` of your chatroom:

from hermes.api import run_server, Chatroom

class BillyMaysChatroom(Chatroom):
command_patterns = ((r'.*', 'shout'),)

def shout(self, sender, body, match):
body = body.upper() #SHOUT IT

chatrooms = {
'world-domination-planning': {
'CLASS': 'BillyMaysChatroom',
'JID': '',
'PASSWORD': 'thesamethingwedoeverynight',
'SERVER': ('', 5223,),
'MEMBERS': [pinky, brain],


## Upcoming Features

* **Persistence**: Allow chatroom configuration/state/history to be persisted

## Is it any good?


Elaborate, you say? Hermes has been successfully used "in production" to run several chatrooms for the Crocodoc team since the first commit. It's good to have guinea pigs.

## License

Hermes is an ISC licensed library. See LICENSE for more details. If you insist on compensating me, I'd let you buy me a beer. Or just donate money to a good cause...that'd probably be best.

## Can I Contribute?

Yes, please do. Pull requests are great. I'll totally add a CONTRIBUTORS.txt when Hermes gets its first contributor.
