Command Description
eru <helloworld|hug|eat|gn|slap|brick|cookie|fixthebot|steal|decide> <message> Joke commands that make the bot do some role-playing actions, some with an optional message. To reduce spam these are disabled in the main #mindcrack channel.
eru time <city>, eru time <person> Outputs the time, day, and location of the city. If a persons location has been entered into a database you can also ask for the time where that person lives.
eru define <word> Tells you what the word is, google define is used as the source of the definitions.
Is not necessary anymore with !calc define <word>
eru help, eru help <command> Gives a list of available commands, or tells you what a specific command does.
eru geoip <ip> Will tell you in what country, and sometimes what city, a specific ip is from.
Is not necessary anymore with !calc <ip>


If a YouTube link is posted in chat, Eru will provide information on the video similar to how it posts YouTube feeds.

In the past, Eru was made to utter random messages, some hilariously confusing. Pakratt0013 used some of Eru's quotes and conversations in many of his YouTube video descriptions. This functionality was moved to the #eruspam channel to reduce spam due to the #mindcrack channel becoming too big, but the conversation generated is still based on what is being said in the #mindcrack channel.

Eru will also help keeping order in the channel and has a ban list the channel ops can add unwanted people to. The feature is mostly used for banning bots, and was added after the channel ban list kept getting full due to a large amount of bots joining the channel.

The bot has a simple and flexible plugin system. If someone wants to write a plugin for the Bot to add useful functionality to the channel it will get accepted. Plugins are written in Perl. Contact TPC to get a copy of an example plugin.
