Around 2013, @horse_ebooks became a very iconic staple in the history of Twitter. I’m gonna teach you how to make your own.
First things first hop on a machine running \*NIX (OS X, Linux, etc)
- If you’re running OS X, open Terminal (found in ~/Applications/Utilities)
- If you’re running Ubuntu, hit Ctrl-Alt+T
- If you’re not on Ubuntu I’d suggest figuring out how to open your Terminal before following this tutorial
Also make sure you have Git installed.
- On OS X, type `git` and hit enter. You should be prompted to install the command-line tools now. If you’ve already installed them your terminal will give you a brief explanation of git and its usage.
- On Linux you should already have git installed.
git clone email@example.com:mispy/ebooks_example nulljosh_ebooks
Then you’ll want to install all of the dependencies (which are in Ruby)
sudo gem install bundler
> This `sudo` trick is a hack and I would suggest against it for them most part. The only reason I’m adding it here is I assume most of you will not touch Ruby again on your machines. If you’re planning on using Ruby in the future, or if you have before, set up a Ruby environment and fix gem permissions, then run this command without root privileges as a less hack-ey method. `sudo` provides root access, which gives you complete God-like control of your machine. You should always be careful with any command you run with it. In this particular case we’re simply installing a few gems/libraries, but always make sure you know what you’re running with it.
Once the dependencies (gems) are installed, npm will be the next thing you’ll need installed.
With npm installed you can install a module Kirby made. You may have to kill Terminal first before running this (remember to `cd` back into your project.)
sudo npm install -g twauth
> Again, the `sudo` command is a hack. Same reasons apply here. In this case we’re installing a module that allows us to authenticate OAuth keys with Twitter.
We’ll use twauth to essentially bypass Twitter’s phone verification, which they have in place to prevent users from abusing apps.
Now would be a good time to create a Twitter account for your bot. Make sure the email is confirmed. Then sign up for a Heroku account, which you’ll be using to deploy your bot to — unless you have your own server in which you can do that yourself. Once you have a Heroku account, download/install the Heroku Toolbelt. Once that’s done, login to Heroku through Terminal:
Now pertaining to what I mentioned earlier about bypassing Twitter’s phone authorization, the easiest way to bypass this is to use already generated public and private/secret keys. Tweetbot’s keys leaked a while ago, so let’s just use theirs.
twauth — key=v8xVBZlXBp2AJoWI3VjDjzDkC — secret=Wpoom4N6tpTgfywzCt6y83gvZubbYoT0vL0V8FXzhyXA74218D
> I’m just gonna slap an “for educational purposes only” on here so I don’t get in trouble. I don’t think that’s gonna help me, though.
Your terminal will now provide you with a link to follow. Open it, sign in with your ebooks account, and you should run into an error message. This is expected. Check the URL, it should look something like this.
Copy the value of `&oauth_verifier`. In this case `4Wg5gzPhxcWrtfgee6Dgg8GwPgahhCRD`. Go back to your terminal and paste this in as your “pin number”. Hit enter and your terminal should respond with two OAuth keys — one public, one private. Keep this terminal window open or copy the keys down — We’ll be using them in a minute
- On line 22 assign `self.consumer_key` to `v8xVBZlXBp2AJoWI3VjDjzDkC`
- On line 23 assign `self.consumer_secret` to `Wpoom4N6tpTgfywzCt6y83gvZubbYoT0vL0V8FXzhyXA74218D`
- Delete line 24 unless you have a reason to keep it.
— On line 131 change “abby_ebooks” to your twitter bot username (username_ebooks, etc)
- One line 132 assign `bot.access_token` to
the first oauth key you got from twauth (the public one)
- On line 133 assign `bot.access_token_secret` to the second key you got (your oauth private).
- On line 135 assign `bot.original` to the username you want to base your ebooks off of (probably your main twitter username)
Flip back to Terminal and make sure you’re still in your ebooks folder. Now you can generate an archive from your tweets.
ebooks archive $username corpus/$username.json
ebooks consume corpus/$username.json
Now comes the unveil — we want to test that the bot is working alright. We can use Heroku’s `foreman` command for that:
Try tweeting your bot now, or maybe follow it. Everything should be working.
We’re almost finished now — we just want to push our bot to Heroku’s servers. First, initialize the git repository, then add all of your work, and commit it:
git add -A
git commit -m “Initial Commit”
Heroku works with git quite nicely so you just need to create it, give it Heroku’s remote, and push it. Also, make sure your Heroku server has an instance of the app.
heroku ps:scale worker=1
git push heroku master
Try tweeting at your ebooks now, see if things are working. Hopefully they are– if they’re not, feel free to tweet me angry things (or ask for help) at @nulljosh.
