The system uses a hybrid blacklisting/whitelisting and AST-traversal approach to both remove dangerous builtins as well as disallow potentially exploitable python structures alltogether. Examples are while structures and attribute allocation. All advanced functionality is accessed through a set of "safe" methods on a holder object. You can extend this with your own safe methods in order to add more functionality befitting your game. The system comes with a host of examples, a few scriptable objects and complete commands for adding code to objects. At this point it's not guaranteed that all systems are safe against meddling however - notably Attributes have no locks defined on them by default (although this system does properly check Attribute lock types should they exixt). Please test and try to break - and report problems to the Issue tracker/forum as usual. |

'Contrib' folder
----------------
This folder contains 'contributions': extra snippets of code that are
potentially very useful for the game coder but which are considered
too game-specific to be a part of the main Evennia game server. These
modules are not used unless you explicitly import them. See each file
for more detailed instructions on how to install.
If you want to edit, tweak or expand on this code you should copy the
things you want from here into game/gamesrc and change them there.
* Evennia MenuSystem (Griatch 2011) - A base set of classes and
cmdsets for creating in-game multiple-choice menus in
Evennia. The menu tree can be of any depth. Menu options can be
numbered or given custom keys, and each option can execute
code. Also contains a yes/no question generator function. This
is intended to be used by commands and presents a y/n question
to the user for accepting an action. Includes a simple new
command 'menu' for testing and debugging.
* Evennia Lineeditor (Griatch 2011) - A powerful line-by-line editor
for editing text in-game. Mimics the command names of the famous
VI text editor. Supports undo/redo, search/replace,
regex-searches, buffer formatting, indenting etc. It comes with
its own help system. (Makes minute use of the MenuSystem module
to show a y/n question if quitting without having
saved). Includes a basic command '@edit' for activating the
editor.
* Talking_NPC (Griatch 2011) - An example of a simple NPC object with
which you can strike up a menu-driven converstaion. Uses the
MenuSystem to allow conversation options. The npc object defines
a command 'talk' for starting the (brief) conversation.
* Evennia Menu Login (Griatch 2011) - A menu-driven login screen that
replaces the default command-based one. Uses the MenuSystem
contrib. Does not require players to give their email and
doesn't auto-create a Character object at first login like the
default system does.
* CharGen (Griatch 2011) - A simple Character creator and selector for
Evennia's ooc mode. Works well with the menu login contrib and
is intended as a starting point for building a more full-featured
character creation system.
