Run command using a mention instead of prefix

[cchudant]

add a configuration option mentionIsPrefix to allow the bot to trigger commands when the prefix of the command is the bot's mention

[lightdiscord]

Unresolved question, should we still run the command if the option is on and the prefix is the bot's prefix (i.e. /) ?

[cchudant]

we should enable the developer to disable prefix by setting it to a falsy value -- '', null or whatever

[lightdiscord]

I thought of something like this

@command(/^command$/i, {
    name: 'Command',
    desc: 'Description',
    prefix: Mode.MENTION_ONLY
})

Where Mode is

const Mode = {
    PREFIX: Symbol('Prefix'),
    MENTION: Symbol('Prefix and Mentions'),
    MENTION_ONLY: Symbol('Mentions only')
}

[cchudant]

this should be configurable not inside the module but in the global config of the bot, no?

I think, we could simplify this a lot Just let the prefix take an array, of string or functions

prefix: ["/", ({ client }) => `${client.user} `]

And let this global setting, be overriden by a command

@command(/^command$/i, {
    name: 'Command',
    desc: 'Description',
    prefix: ["/", ({  client }) => `${client.user} `]
})

And that can also be a function

@command(/^command$/i, {
    name: 'Command',
    desc: 'Description',
    prefix: ({ client }) => client.settings.prefix.concat([({ client }) => `${client.user} `])
})

we need the length to remove from the message in order to pass it to the regexes
