About Evennia
-------------

Evennia is a MUD/MUX/MU* server that aims to provide a functional
bare-bones base for developers. Some of our main features are: 

* Coded and extended using normal Python modules.
* Extensive web integration due to our use of Django. 
* Runs its own Twisted webserver. Comes with game website and ajax web-browser mud client. 
* Extensive current and potential connectivity and protocol-support through Twisted.
* Extremely easy-to-manipulate SQL database back-end via Django 
  (djangoproject.com)
* Powerful an extremely extendable bare-bones base system 

The Django framework has database abstraction abilities that give us
many features free, such as:

* The codebase will run transparently on MySQL, SQLite, or Postgres
* At the time of this document's writing, our SQL-backed application here
  contains 0 lines of SQL. Django's database abstraction layer is absolutely
  simple yet very powerful.
* For any model we outline for the server's use, we have the ability to
  more or less automatically generate a web-based admin interface for it with
  two lines of code. This lets you Create, Update, or Delete entries, as well
  limit permissions for those abilities.
* On the web-based side of things, features such as automatic form validation,
  abstraction of sessions and cookies, and access to whatever game data you
  desire are all attractive.  

See the INSTALL file for help on setting up and running Evennia. 


Current Status
--------------

Nov 2011: 
After creating several different proof-of-concept game systems (in
contrib and privately) as well testing lots of things to make sure the
implementation is basically sound, we are declaring Evennia out of
Alpha. This can mean as much or as little as you want, admittedly -
development is still heavy but the issue list is at an all-time low
and the server is slowly stabilizing as people try different things
with it. So Beta it is!

Aug 2011:
Split Evennia into two processes: Portal and Server. After a lot of
work trying to get in-memory code-reloading to work, it's clear this
is not Python's forte - it's impossible to catch all exceptions,
especially in asynchronous code like this.  Trying to do so results in
hackish, flakey and unstable code. With the Portal-Server split, the
Server can simply be rebooted while players connected to the Portal
remain connected. The two communicates over twisted's AMP protocol.

May 2011: 
The new version of Evennia, originally hitting trunk in Aug2010, is
maturing. All commands from the pre-Aug version, including IRC/IMC2
support works again. An ajax web-client was added earlier in the year,
including moving Evennia to be its own webserver (no more need for 
Apache or django-testserver). Contrib-folder added. 

Aug 2010:
Evennia-griatch-branch is ready for merging with trunk. This marks a
rather big change in the inner workings of the server, such as the
introduction of TypeClasses and Scripts (as compared to the old
ScriptParents and Events) but should hopefully bring everything
together into one consistent package as code development continues.

May 2010:
Evennia is currently being heavily revised and cleaned from 
the years of gradual piecemeal development. It is thus in a very 
'Alpha' stage at the moment. This means that old code snippets
will not be backwards compatabile. Changes touch almost all
parts of Evennia's innards, from the way Objects are handled 
to Events, Commands and Permissions. 

April 2010: 
Griatch takes over Maintainership of the Evennia project from
the original creator Greg Taylor. 

(Earlier revisions, with previous maintainer, go back to 2005)


Contact, Support and Development
-----------------------
This is still alpha software, but we try to give support best we can
if you have questions. Make a post to the mailing list or chat us up
on IRC. We also have a bug tracker if you want to report
bugs. Finally, if you are willing to help with the code work, we much
appreciate all help!  Visit either of the following resources:

Directory structure
-------------------
evennia
 | 
 |_______src
 |        |___(engine-related dirs)
 |        
 |_______game (start the server)
 |        |___gamesrc
 |              |___(game-related dirs)
 | 
 |_______contrib 
 |
 |_______docs 
 |
 |_______locales

The two main directories you will spend most of your time in
are src/ and game/ (probably mostly game/). 

Basically src/ contains everything related to 
running the gritty stuff behind the scenes. Unless you are an
Evennia developer you should normally make sure never to edit 
things in src/, since this is where we push new revisions that
may overwrite your changes when you update. You will however 
need to have a good feeling for the resources supplied by 
the functions in src, since accessing them correctly is the key 
to making your dream game come true. 

If src/ is the Evennia developer's domain, the game/ directory 
on the other hand contains YOUR game. This is where you will 
define and extend the commands, objects and systems of Evennia
to make your dream game. game/ contains the main server settings
and the actual evennia executable to start things. game/gamesrc/
holds all the templates for creating objects in your virtual world. 

contrib/ contains optional code snippets. These are potentially useful
but deemed to be too game-specific to be part of the server itself.
Modules in contrib are not used unless you yourself decide to import
and use them.

docs/ contain offline versions of the documentation, you can use 
python-sphinx to convert the raw data to nice-looking output for 
printing etc. The online wiki is otherwise first to be updated.  

locales/ holds translations of the server strings to other languages
than English.

With this little first orientation, you should head into the online 
Evennia wiki documentation to get going with the codebase.
