TwiCmd

TwiCmd is a small node module which enables triggering commands on a remote server using your public twitter stream.

Out hiking and need to restart nginx or run a script? Send a short Tweet

Connect it to your lights and use twitter to turn them on and off

###Concerns

• My twitter stream is public, commands could reveal to much about the computer I am controlling. True, but you can name commands what ever you want. For example #yolo #bro to restart a service or clear a log.
• It's not verbose enough. Any problem that can be diagnosed and fixed using a script is a potential candidate for a command

###Motivation

• Everyone has Twitter (almost)
• Twitter is available on all platforms (almost)
• Twitter is mobile
• Twitter handles authentication
• SSH access is not as mobile

Examples

###Javascript

var TwiCmd = require("twicmd"),
	twitter = require("twitter"),
	twicmd, twitt;

twitt = new twitter({
	consumerKey: "Consumer key here",
	consumerSecret: "Consumer secret here",
	accessTokenKey: "Access token here",
	accessTokenSecret: "Access Secret here"
});

twicmd = new TwiCmd({
	tweetProvider: twitt,
	tweeters: ["xxxxxxxx"], //Numerical twitter ids
	commands: {
		test: function () { //Command triggered by #test
			console.log("test");
		}
	},
    //Tag needed to invoke a command besides the command tag
    //Defaults to #twicmd
	invokingTag: "#myCustomInvokingTag"
});

twicmd.addCommand("rs", function () {
	console.log("Restart a service")
});

twicmd.start();

setInterval(function() {},5000); //Prevent process shutdown

###Coffeescript

TwiCmd  = require("twicmd")
twitter = require("twitter")

twitt = new twitter
                consumerKey: "Consumer key here"
                consumerSecret: "Consumer secret here"
                accessTokenKey: "Access token here"
                accessTokenSecret: "Access Secret here"

twicmd = new TwiCmd
                tweetProvider: twitt
                tweeters: ["xxxxxxxxxxx"] #Numerical twitter ids
                commands:
                        test: ->    #Available command triggered by #test
                            console.log "Test"
                invokingTag: "#mycustominvokingtag"

twicmd.addCommand "rs", () ->
    console.log "Restart a service"

twicmd.start()

setInterval (->), 5000 #Prevent process shutdown

###TwiCmd Constructor TwiCmd (parameters)

####tweeters

An array of twitter ids specifying who can trigger commands. Only direct tweets from these tweeters can trigger commands. If the array is left empty twicmd runs in public mode were anyone can trigger commands, this is not recommended.

####Commands An object representing the available commands. Each key will represent a command. Commands are invoked by using them in tweets as hashtags along with the invoking tag. The value of each key should be a function to run when the command is triggered.

Example

{
	restart: function () {/* … */},
	stop: function () {/* … */}

}

Triggering the restart command is done with the following tweet #twicmd #restart given that the invoking tag has not been changed from the default.

####TweetProvider A tweet provider. The node module twitter is suggested. The tweet provider should provide a method called stream with the same signature as the stream method in the twitter module.

####invokingTag

The extra tag required to invoke a command besides the command tag.

Default: #twicmd
