A basic line-oriented chat server built atop step 4 of the pony-workshop used as a learning example.

It features:

graceful shutdown of the server (triggered by sending SIGTERM and SIGINT)
logging which can be controlled via PONY_LOG_LEVEL environment variable
requires clients to provide their names
clients can send:
- /quit - terminate the client's connection to the server and announces that this client has left
- /time - the server sends the current time to the server
- everything else is sent to all connected clients

Requirements

Build

ponyc

Note: the server listens for connections on localhost:8989

./main

To run with various log levels:

PONY_LOG_LEVEL=<log-level> ./main

Where <log-level> is one of fine, info, warn, error

The easiest way to connect to the server is to use netcat like so:

> nc localhost 8989
