IRC is built on an open standard, allowing you to host it asa service (on your own hardware), or from within a

private network (for added security).

OpenShift was designed with many of the samecharacteristics in mind, minus the drama.

CONFIGURING YOUR DEV ENVIRONMENTWill automatically:

set your openshift email addressverify your ssh key configurationconfigure your application namespace

rhc setup



GEARING UP A NEW APP ON OPENSHIFTor

rhc app create APP_NAME APP_CARTRIDGE

rhc app create ircbot nodejs-0.6



Application Options------------------- Namespace: ryanj Cartridges: nodejs-0.6 Gear Size: default Scaling: no

Creating application 'ircbot' ... done

Waiting for your DNS name to be available ... done

Downloading the application Git repository ...Cloning into 'ircbot'...



ircbot @ http://ircbot-ryanj.rhcloud.com/ (uuid: 25918304bf8d406e89802a1e642063a0)--------------------------------------------------- Created: 10:23 PM Gear Size: small Git URL: ssh://[email protected]/~/git/ircbot.git/ SSH: [email protected]

nodejs-0.6 (Node.js 0.6) ------------------------

RESULT:Application ircbot was created.



SUCCESS!You now have a basic node.js app up an running on

OpenShift!

Your gear is now configured with:

it's own git repoit's own web serverssh accessloggingpublicly accessible DNS



BUILDING YOUR BOT cd ircbot



INSTALLING DEPENDENCIESUsing Node's :

Include the `-S` flag in order to save this dependency toyour application's `package.json` file.

npm package managernpm install irc -S

http://npmjs.org/package/irc/

https://npmjs.org/

http://npmjs.org/package/irc/



BOT BASICSAdd the following to your server.js to load and configure

the irc library:var irc = require('irc');var bot_name = process.env.OPENSHIFT_APP_NAME || 'ircbot';var bot = new irc.Client('chat.freenode.net', bot_name, { channels: ['#botzoo', '#botwar'], port: 8001, debug: true});



TEACHING YOUR BOT TO SPEAKListen and respond to conversations as they happen:bot.addListener('message', function(from, to, message) { if( message.indexOf('Know any good jokes?') > -1 || message.indexOf('good joke') > -1 ) { bot.say(to, 'Knock knock!'); }});



Getting to the punchline:bot.addListener('message', function(from, to, message) { if( message.indexOf('who is there?') > -1 || message.indexOf("who's there?") > -1 || message.indexOf("Who's there?") > -1 || message.indexOf("Who is there?") > -1 ) { bot.say(to, 'Doris'); }});bot.addListener('message', function(from, to, message) { if( message.indexOf('Doris who?') > -1 || message.indexOf("doris who?") > -1 ) { bot.say(to, "Doris locked, that's why I'm knocking!"); }});



COMMITTING YOUR CHANGESgit add package.json server.jsCommit your changes locally

git commit -m 'adding irc npm dependency, initializing irclibrary, adding a few jokes'



DEPLOYMENTDone! Your bot should now be live on IRC.

git push



INTERACTING WITH YOUR NEW BOTLogin to IRC, and enter one of the channels that your bot

has been configured to join:

If you don't already have an IRC client, you can connect tofreenode on the web:

/join #botzoo





Ask if anyone knows a good joke:[guest] Know any good jokes?[ircbot] Knock knock![guest] Who is there?[ircbot] Doris[guest] Doris who?[ircbot] Doris locked, that's why I'm knocking![guest] meh...



BOT DEBUGGING AND MAINTAINANCEIf your bot decides to quit mid-conversation, it may be

suffering from a bug.

Checking it's logs may reveal what set it off:

Or, debug it while running locally:

rhc tail ircbot

npm start



TEACHING YOUR BOT TOKEEP SCORE



SETTING UP MONGODB ON OPENSHIFTrhc cartridge add mongodb-2.2



Adding mongodb-2.2 to application 'ircbot' ... Success

mongodb-2.2 (MongoDB NoSQL Database 2.2)---------------------------------------- Connection URL: mongodb://127.6.102.129:27017/ Database Name: ircbot Password: T5xJwCiDZYGn Username: admin

RESULT:Added mongodb-2.2 to application ircbot



Adding mongodb-2.2 to application 'ircbot' ... Success

MongoDB 2.2 database added. Please make note of these credentials:

Root User: admin Root Password: T5xJwCiDZYGn Database Name: ircbot

Connection URL: mongodb://$OPENSHIFT_MONGODB_DB_HOST:$OPENSHIFT_MONGODB_DB_PORT/

You can manage your new MongoDB by also embedding rockmongo-1.1The rockmongo username and password will be the same as the MongoDB credentials above.



ROCKMONGO ON OPENSHIFT(optional)

rhc cartridge add rockmongo-1.1



ADDING A MONGOJS DEPENDENCYnpm install -S mongojs



CONNECTING TO MONGODBvar mongojs = require('mongojs');var connection_string = bot_name;if(process.env.OPENSHIFT_MONGODB_DB_PASSWORD){ connection_string = process.env.OPENSHIFT_MONGODB_DB_USERNAME + ":" + process.env.OPENSHIFT_MONGODB_DB_PASSWORD + "@" + process.env.OPENSHIFT_MONGODB_DB_HOST + '/' + process.env.OPENSHIFT_APP_NAME;}var db = mongojs(connection_string, ['scoreboard']);



SETTING A SCOREbot.addListener('message', function(from, to, message) { if( message.indexOf('++') > -1 ){ var subject = message.slice(0,message.indexOf('++')); db.scoreboard.find({query: {name: subject}}).limit(1, function(err, doc) { if( typeof(doc)=='object' && (doc instanceof Array) && doc[0] && doc[0].name){ // update db.scoreboard.update({name: subject}, {$inc:{score:1}}, function(err) { bot.say(to, "score: " + ( 1 + doc[0].score )); }); }else{ // insert db.scoreboard.insert({name: subject, score: 1}, function(err) { bot.say(to, "score: 1"); }); } }); }});



SHOWING THE SCOREBOARDbot.addListener('message', function(from, to, message) { if( message.indexOf('scoreboard') > -1 ){ db.scoreboard.find().sort({score:-1}).limit(10).forEach(function(err, doc){ if (doc && doc.name && doc.score ) { bot.say(to, doc.name + ": " + doc.score); } }); }});



UPDATING YOUR APPgit add package.json server.js

git commit -m 'adding a social scoreboard'

git push
