## Command
|
|
|
|
Handles the command execution logic for DBot.
|
|
|
|
### Description
|
|
|
|
Command flow:
|
|
|
|
1. Does the input match a command key in the loaded commands?
|
|
* If command not found and quotes is loaded, attempt to print quote of given
|
|
command name
|
|
2. Is the user banned from running the given command?
|
|
3. Is the user ignoring the command?
|
|
4. Is the channel ignoring the command?
|
|
5. Does the use have the access level to run the command?
|
|
6. Is the command set as disabled?
|
|
7. Apply regex to the command, pass into event object.
|
|
* If regex does not apply, show usage info.
|
|
8. Run the command.
|
|
|
|
This is the only module which is force loaded, even if it's not specified in
|
|
the configuration file.
|
|
|
|
### Config
|
|
|
|
#### useNickserv: false
|
|
Use the nickserv module to ensure a user is logged into their account before
|
|
running any elevated commands. Note you will still have to load and configure
|
|
the nickserv module yourself.
|
|
|
|
#### accessOutput: false
|
|
Show a message to a user if they attempt to run a command they don't have the
|
|
access level for.
|
|
|
|
### 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.
