Gossip pub-sub examples

General description

  • gossip_chat_example.cpp shows how to use Gossip pub-sub
  • utility.cpp and console_async_reader.* contain common things related to examples

Launching

gossip_chat_example

./gossip_chat_example -p PORT [-t TOPIC] [-r REMOTE] [-l LOG_LEVEL]

Longer strings for options are available, respectively --port, --topic, --remote, and --log

  • PORT : port the local node is going to listen to
  • TOPIC : topic name for chat messages
  • REMOTE : p2p URI of bootstrap peer to connect to
  • LOG_LEVEL: verbosity level of log output, possible values are d, i, w, or e (self explained)

After launching, you may type messages into console, which are being published into the topic. Log messages are printed intostdout. Chat output is written to stderr. So logs may be redirected if needed

Explanation by example: ./gossip_chat_example --log=d -p 1300 -r /ip4/192.168.0.104/tcp/10000/p2p/12D3KooWLm1CRdj8DBhwAfMGEcNGCEm3ZWxL6jD6uC6BizqXGcP6 means that

  • Logs will be printed with debug verbosity level
  • local node will listen to port 1300 and try to connect to remote peer given by uri
