dbot/modules/command

Command

Handles the command execution logic for DBot.

Description

1. Does the input match a command key in dbot.commands ?
2. Is there a quote category which matches the first part of the input (~category)?
3. Is there a command name similar to to the first part of the input (~name) in dbot.commands?

This is the only module which is force loaded, even if it’s not specified in the configuration file.

Commands

~usage command

Show usage information for a given command.

~help [command|module]

Link module help for a module given either the module name or the name of a command belonging to a module.

API

isBanned(user, command)

Return whether a user is currently banned from a given commands.

hasAccess(user, command)

Return whether a user has the access level (moderator, admin) to run a given command.

isIgnoring(user, command)

Return whether a user is currently marked as ignoring a given command.

addHook(command, callback)

This API function allows you to hook functions into DBot commands. For example, you may add a hook to post on Identica when a new quote is added to the database with the ~qadd command. As a less useful example, here is how you might add a hook to log to the console every time someone uses the reload command:

dbot.api.command.addHook('reload', function() {
    console.log('Reload run!');    
});

Hook arguments are populated by the return values of the functions they are hooked into, and command hooks are not run if the command explicitly returns ‘false.’ For example, the ~qadd command returns [ key, quote ], and the hook function will be called with these variables given in the order they were returned, so you would retrieve the key and the quote from a hook to ~qadd like this:

dbot.api.command.addHook('~qadd', function(key, quote) { ...

The best place to add hooks to commands is in the ‘onLoad’ function of your module, as this ensures it will be run while all other modules are loaded. If the target command does not exist (for example if its module was not loaded), the hook will not be added and no errors will be thrown.
