I’m Corey Woodcox. I work for saxton|horne Advertising. I love
Ruby, Github and Apple. And most importantly... Things You Should Know

Now, wait a second... I’ve never done this before, I
hope you know. Pry doesn’t look like it could cover a 30 minute session... Despite all this, which they pointed out to me, they still selected my proposal...?

GET ON WITH IT

WTF is Pry? Ruby REPL

WTF is REPL? Read Evaluate Print Loop

WTF is REPL? irb coffee php -a ielm Chrome JS
console

WTF is REPL? irb coff hp -a ielm me JS
sole Any console, really...

Cool, IRB is great! Well, guess what. Pry is better!

Well... So what? A REPL? We have got a REPL.
There can be no more REPL. FALSE. Vanilla IRB kinda sucks, guys.

But! But!!!1 No really, it does. Try dropping irbtools-more into
~/.irbrc, work with it for a day, then turn it off.

Again I ask, why? Pry has lots of awesome features
that make it cooler than IRB. O RLY??

Easy Shell Access! Open your editor, kill your zombie process,
browse your source... Even with Ruby!!

Object Browsing With bash-style directory browsing goodness!

Browse Source Need to know where a method is?

Editor Integration

Editor Integration Pry open a ﬁle or a method in
your favorite editor! BOOM.

Gists Lots of gist commands and stuff, more on that
later as well.

Let’s Review I have absolutely no idea what I’m doing.
REPL = Read, Evaluate, Print loop IRB sucks Pry rocks my socks Pry-Remote makes remote debugging more awesomer
