Creation of custom package

[admin]

Attached is websocket client library ported from https://github.com/lipp/lua-websockets/

Main changes:
1. Support for basic auth in URL
2. Receive timeout does not close the websocket connection
3. Server support is removed

Add it as a user library named websocket

Minimal example (resident script):

Code:

if not ws then
  ws = require('user.websocket')
  url = 'ws://admin:admin@192.168.1.12/apps/localbus.lp'
  -- mode is either sync or copas, second parameter sets timeout in seconds
  client = ws.client('sync', 10)
  client:connect(url)
end

log(client:receive())
