# Install MUGS (expect precompilation to take a while)
zef install --exclude="pq:ver<5>:from<native>" MUGS

# Create a long-lived (on disk) data set and identity universe
mugs-admin create-universe [<universe-name>]  # Defaults to "default"


# Play games using a local UI, using an internal stub server and ephemeral data
mugs-cli  # Turn-based CLI

# Play games using an internal stub server accessing the long-lived data set
mugs-cli --universe=<universe-name>

# Log in and play games on a WebSocket server using a local UI
mugs-cli --server=<host>:<port>


# Start a TLS WebSocket game server on localhost:10000 using fake certs

# Specify a different MUGS identity universe (defaults to "default")
mugs-ws-server --universe=other-universe

# Start a TLS WebSocket game server on different host:port
mugs-ws-server --host=<hostname> --port=<portnumber>

# Start a TLS WebSocket game server using custom certs
mugs-ws-server --private-key-file=<path> --certificate-file=<path>

# Write a Log::Timeline JSON log for the WebSocket server
LOG_TIMELINE_JSON_LINES=log/mugs-ws-server mugs-ws-server


# Start a web UI gateway on localhost:20000 to play games in a web browser
mugs-web-simple --server-host=<websocket-host> --server-port=<websocket-port>
mugs-web-simple --server=<websocket-host>:<websocket-port>

# Start a web UI gateway on a different host:port

# Use a different CA to authenticate the WebSocket server's certificates
mugs-web-simple --server-ca-file=<path>

# Use custom certs for the web UI gateway itself

MUGS is a set of basic services written in the Raku language for creating client-server and multi-user games. It abstracts away the boilerplate of managing player identities, tracking active games and sessions, sending and receiving messages and actions, and so forth.

This Proof-of-Concept release includes a simple local CLI UI, a WebSocket-based game server, a Web UI gateway, and simple admin and developer tools. It can store data using either an internal ephemeral/test storage driver, or in SQLite databases on disk using a storage driver based on the Red ORM.

This release also includes a small selection of very simple games to exercise the basic infrastructure and services.


MUGS is still in its infancy, at the beginning of a long and hopefully very enjoyable journey. There is a draft roadmap for the first few major releases but I don't plan to do it all myself -- I'm looking for contributions of all sorts to help make it a reality.


Please do! :-)

In all seriousness, check out the CONTRIBUTING doc (identical in each repo) for details on how to contribute, as well as the Coding Standards doc for guidelines/standards/rules that apply to code contributions in particular.

The MUGS project has a matching GitHub org, Raku-MUGS, where you will find all related repositories and issue trackers, as well as formal meta-discussion.

More informal discussion can be found on IRC in Libera.Chat #mugs.
