All commands are prefixed with a /. So if you want to execute the command foo, you must write:

!!/foo

Where the !! is the Invocation Pattern (see main, subject to change by bot handler. In this wiki, !! is assumed). The general form being:

!!/commandName [arg0 [arg1 [...]]]

Some commands require special privilege to use (as in, you must be a room owner or a moderator). Having said that, there are...

In those privileged commands, there's a small subset that while normally requiring special privilege, will be triggered once enough (usually 2) users invoke them within a span of time. At the time of writing, these are

• ban
• die
• summon and unsummon

The reason being the community should have the power to prevent spam in case something goes wrong with the bot, or a user is abusing it.

This wiki assumes (for demonstration purposes) that your username is Dave, your user-id is 5318008 and the message you sent has an id of 42.

!!help [cmdName]

Fetches documentation for given command, or general help article.

When called with no arguments, returns a link to the main wiki page. When called with an argument cmdName, it displays a help message for the specific commands.

!!help

!!help spec
@Dave spec: Find a section in the ES5 spec
!!help unexisto
@Dave Command unexisto does not exist.

!!listen stuff

Forwards the message to my ears. Explicitly try and invoke a listener. Useful for /tell.

!!tell Bob listen give me a lick
@Bob Mmmm! you taste just like raisin

!!eval 4+6
:42 10
!!> 4+6
:42 10

Forwards message to coffeescript code-eval, equivalent to the c> prefix.

!!coffee not yes
:42 false
!!c> not yes
:42 false

!!refresh

(Owner only) Reloads the browser window I live in.

!!forget cmdName

Forgets a given command. You may have to have permission to forget certain commands (only commands you taught via /learn; owners can delete any /learned command).

!!info [cmdName]

Grabs some stats on my current instance or a command.

When called without an argument, returns stats on the current bot instance (uptime and so forth). With an argument, returns meta-data on a command (when it was learned, by whom, etc).

!!listcommands

Lists commands. Whoop de doo.

!!tell msg_id|usr_name cmdName [cmdArgs]

Redirect command result to user/message.

!!tell Bob listcommands
@Bob [...listcommands stuff....]
!!tell 253961 listcommands
:253961 [...listcommands stuff...]

/afk message

Set an afk message. After a few minutes of away time, if a user pings you, the bot will reply with the message.

Dave: !!afk hurricane
[...some time passes...]
Alice: @Dave Did you survive?
Bot: @Alice Dave is afk: hurricane.

!!ban [usr_id|usr_name]

(Communal command) Bans a user from using me. Lacking arguments, prints the ban list.

Assuming a user called Yarbal (uid=400), and another user with an id of 890 not present in the room:

!!ban 890
@Dave User 890 added to mindjail.
!!ban Yarbal
@Dave User Yarbal added to mindjail.
!!ban
@Dave 890 (?), 400 (Yarbal)
!!ban unexisto
@Dave Cannot find user unexisto.

!!unban usr_id|usr_name

(Owner only) Frees a user from my mindjail.

!!convert <num><unit> [to|in <unit>]

Converts a unit of measurement to its counterparts (e.g. degrees to radians.) Units are case-sensitive (e.g. F is Farrenheit, f is feet, and c does not map to C (Celsius)). Can also convert most currencies using a rate-exchange API.

!!convert list

Displays a list of known units. Just the units. No explanations. If you don't know what the units mean, you probably don't need them, or you can experiment and see.

!!convert 100C
@Dave 212F, 373.15K
!!convert 1240g to st
@Dave 0.1952st

Money conversions are a bit trickier. This command tries to be lenient, accepting most currency ISO codes in both lowercase and uppercase and mapping some currency symbols (like € to EUR and ₹ to INR), but it'll break if you try to be a smartass (like /convert 10 bucks). Also note that there must be a target currency: One cannot simply convert one currency into all the rest.

!!convert 100USD to EUR
@Dave 76.5579EUR
!!convert 100USD to ₨
@Dave 5413.0128INR

!!define something

Fetches definition for a given word.

!!doge one,two,three[,nth]

so shibe, much doge, wow.

!!google stuff

Returns the first 3 results of googling query. Note that the query is passed verbatim, so you can go wild on query modifiers (like site:, inurl:, quoting, etc.)

!!hang [guess]

Starts a Hangman game if none is running, or send a guess to the one currently running.

!!jquery stuff [moreStuff]

Fetches jquery documentation link to stuff.

!!learn commandName outputPattern [inputRegex [description]
!!learn greet "Hello, $0!" \w+
!!learn greet 'Hello, $0!' \w+ 'summons the lord'

An alphanumeric, dash - and underscore _ string, self explanatory

A string passed to /parse (see above for doc), with the matched groups ($0, $1, ... for the capture-groups in inputRegex) as the extra variables.

By default, invoking a taught command will reply to the user who invoked it. However, you can prepend your command with a modifier to change how it'll be outputted:

Lacking anything, it defaults to <user>. Examples:

!!/learn messageReply "<msg> this is a message reply"
!!/messageReply
:42 this is a message reply

!!/learn direct "<> this is a direct message"
!!/direct
this is a direct message

A regular expression, which will be matched against the command arguments.

Defaults to .*

Optional. Additional info displayed when the command is /helped.

!!die

(Communal command) Kills me :(
