The mudpy project aims to create a simple, generic, cross-platform, freely-redistributable MUD core engine which can be easily understood and extended. It is written in pure Python 3 and has only pure Python dependencies. All configuration and data are stored in consistently-formatted plain text (YAML 1.1) files for ease of administration. The core engine is unicode-clean internally and supports UTF-8 encoding for input and output of extended text characters.

The mudpy program and sample content are released under a free and open license, and any bug reports, criticisms, ideas, patches, content submissions or other offers of collaboration are wholeheartedly welcome.

what's missing

This project is still very much a work in progress, and is unlikely to be suitable for anyone who isn't willing to put in a bunch of work (help implementing features upstream is welcome, of course!). Here's a non-comprehensive list of missing things most folks are likely to expect in a MUD:

interactive objects/props
inventory/equipment management
non-player characters
a default combat system
sample races/classes and spells/skills
example implementation of character stats/progression
closeable/lockable portals
ability to change randomly-generated avatar names
pagination of the output stream

what's included

The fundamentals of a multi-user service are in place, and foundations are laid on which the missing features above can be built. Here are some highlights of what's been implemented so far:

the beginnings of a MUD framework
- account creation, authentication and lobby menus
- movement between rooms/locations with inferred portals
- in-room communication between users
- setting and viewing user preferences
- an integrated command help system
- world creation and introspection commands for admins
- live reloading of configuration and source code
a full-featured Telnet service with a focus on IETF RFC compliance
- RFC 854 Telnet protocol
- RFC 856 binary mode
- RFC 857 echo control
- RFC 858 go-ahead suppression
- RFC 885 end-of-record transmission
- RFC 1091 terminal type
- RFC 1073 window size negotiation
- RFC 1184 line-at-a-time input mode
- RFC 1143 "Q method" negotiation state engine
mature development practices
- traditional Python distutils/setuptools/pip packaging
- comprehensive regression and style testing
- minimal runtime dependencies
- extensive logging
- flexible, generalized data model
- in-repository documentation
