h1. Dicebot
|
|
|
|
All dicebot commands support four special features not available to other commands:
|
|
|
|
* @.help@ gives usage information and a description of the command.
|
|
* @.<command>-as <nick>@ processes the command as though @nick@ had used it.
|
|
* @.<command>-to <nick>@ sends the output of the command to you and @nick@ as a private message.
|
|
* @.<command> ; <comment>@ appends the comment to the end of the command's output.
|
|
|
|
The following commands are associated:
|
|
|
|
* @.attrib@ generates D&D dice-rolled attributes.
|
|
* @.silcore@ rolls dice for Silhouette Core.
|
|
* @.exalted@ rolls dice for Exalted 2e; @.exalted <dice> 6@ may be used for old World of Darkness.
|
|
* @.hellcats@ rolls dice for Hellcats & Hockeysticks.
|
|
* @.fudge@ rolls dice for Fudge and Fate, and supports the Fate ladder.
|
|
* @.lonewolf@ rolls a die for the Lone Wolf gamebooks and tabletop game.
|
|
* @.dryh@ rolls dice for Don't Rest Your Head.
|
|
* @.dw@ rolls dice for Dungeon World and variants.
|
|
* @.swrpg@ (and aliases @.eote@, @.aor@, and @.fad@) rolls dice for the Star Wars RPG tabletop game.
|
|
* @.roll@ and @.math@ are more generic; the former allows for multiple formulas to be calculated at once, whereas the latter allows spaces to be used to make formulas more legible.
|
|
|
|
The @.roll@ and @.math@ commands support the following:

h1. Database Commands
|
|
|
|
Chessa has a pluggable database interface, which provides a common interface for database-related functionality. Currently, the following plugins exist:
|
|
|
|
* Pronouns: Simple database mapping users to their pronouns. Presets are available for male, female, and neutral.
|
|
* Time: Timezone and current time for users.
|
|
|
|
Plugins are accessible via @.<plugin>@, with the following subcommands:
|
|
|
|
* @find@ looks up the requested user.
|
|
* @set@ allows the user to set data for the particular plugin.
|
|
* @help@ provides documentation for the plugin.
|
|
|
|
If no subcommand is provided, @find@ is assumed. For example, @.time US/Eastern@ gives the time in that timezone.
|
|
|
|
h1. Weather
|
|
|
|
The weather command set consists of @.weather@, @.f@/@.f1@/@.f3@, @.alerts@, and @.location@. All commands take a query string and, optionally, a semicolon (@;@) followed by a country designator. This designator will constrain the query to the given country, in cases where an ambiguous query may return an unexpected result (e.g. @.weather hell@ might return the weather for Hellin, Spain, whereas @.weather hell;no@ will return the weather for Hell, Norway).
|
|
|
|
@.f@ returns today's forecast, @.f1@ returns tomorrow's forecast, and @.f3@ returns (via PM) the forecast for the three days following today. Note that the forecast will change over at 00:00 local time.
|
|
|
|
@.location@ stores the provided location for the user, so as to allow future inquiries to omit a query string.
|
|
|
|
h1. Other Commands
|
|
|
|
* @.choose@ returns a randomly-chosen entry from a list, delimited by a comma followed by a space.
|
|
* @.unicode@ returns information on the given Unicode sequence. Supports combining characters.
|
|
* @.uniname@ returns information on the given Unicode named sequence.
