An IRC bot

design (in short; see Jaken (r3boot) for full)

GHBot listens on a few MQTT topics. Plugins can send commands to GHBot via those.

  • topic: GHBot/to/bot/register
    • value: cmd=...|descr=...|agrp=...|athr=...|loc=...
      • cmd=... defines (one of) the command(s) this plugin listens to (required)
      • descr=... short description of what the cmd does. this is returned by "!help cmd" (required)
      • agrp=... ACL group required for this command (optional, default is access for everyone)
      • athr=... author (optional)
      • loc=... where it lives (optional), for when e.g. the plugin is running on an arduino somewhere hidden
    • you should send this every 5 seconds or a command will disappear automatically
  • topic: GHBot/to/irc/channel/privmsg
    • value: text to publish to channel - note that the '#' in the channel name must be omitted
  • topic: GHBot/to/irc-person/nick
    • value: text to send to the person nick in a PM

GHBot also sends everything it receives via IRC to MQTT topics, for the plugins to be processed.

  • topic: GHBot/from/bot/command
    • value: register - asks all plugins to immediately register all the commands it knows (see above)
  • topic: GHBot/from/bot/parameter/prefix
    • value: command-prefix (e.g. '!' or '#' etc) this command asks plugins to respond to commands prefixed by this prefix.
  • topic: GHBot/from/irc/ - please see r3boot's documentation

user management

  • add a user:
    • addacl user nick group groupname
      • nick is the nickname of the user, ghbot will lookup the full name etc of the user by itself
      • group is currently either members or sysops but you can create new groups easily (by either defining them in a plugin or using addacl group, see below)
  • create a new group:
    • addadcl group groupname cmd command
      • groupname is the new group, command is the (existing) command that you want to put in the new group
  • delete a group:
    • delacl
  • get a list of groups a user is in:
    • listacls nick
  • connect a nick to a new hostname:
    • meet nick

aliasses / defines

  • aliasses are for commands, defines are "new commands"
    • alias new_command_name old_command_name
      • returns a number with which you can delete the alias
    • define new_command_name command definition
      • escapes:
        •  %q command parameter
        •  %u user invoking the command
        •  %m like '/me'
      • returns a number with which you can delete the alias
    • deldefine number
      • delete an alias or define

  • Make internal states accessible over mqtt (Plugins plugins loaded) -- see next item:
  • Have plugins being able to report author and location for easier keeping track (Melan: My idea is to make a plugin that can make a page that can output all commands + help etc to a markdown on request) -- finished altough the layout may be pimped a bit
  • !seen
  • remove the silly http-implementation and/or add an http-api that allows to retrieve the plugin-state as a json-blob
    • also post-to-channel api

Feature Requests

  • r3boot Overzicht van plugins die herschreven moeten worden naar de nieuwe plugin structuur
    • zie hierboven
  • r3boot RSS feeds beperken tot nurdspace resources, of verplaatsen naar #nurds-feeds kanaal oid
    • feeds verwijderd :-)
  • r3boot Plugin output prefixen met de naam v/d plugin zodat filtering voorspelbaar word.
    • dit is iets wat de plugin zelf moet doen omdat de bot niet ziet wie de afzender is (die info zit niet in mqtt)
  • r3boot Overzicht van operaties die beheerders kunnen uitvoeren op de bot (ops documentatie)
  • The_Niz Partkeepr search
  • The_Niz !btc in Eu ipv die nare dollah units
    • ik heb geen conversie dingetje naar euro, suggesties welkom though
  • iets met dat je kunt configureren of iets een PRIVMSG of dat het een NOTICE is - hoewel kan een plugin dat niet al?

  • r3boot Apply acceptable regex to incoming karma requests (eg: ^[a-zA-Z0-9_-]+{\+\+,--}$. This will prevent multikarma and calling the plugin multiple times.

  • !message (zie kiki: !boodschap)
    • added
