“g” is very useful

      @jugyo
Hi
My name is @jugyo
I’m a member of
“Everyleaf Corporation.”
This is my first
presentation in english.
I talk about
a very useful method
          “g”
You know “p”
It shows
information of objects
“p” is useful for
   debugging
But,
in some case
“p” is not useful.
For example,
rails
Rails outputs many
       texts
   to STDOUT.
like this
I use “p” to output
information of an object
However, I can’t find it.
In such case,
I use “g”
What is “g”?
“g” is like “p”
“g” outputs
information of an object
       to “growl”
like this
Usage
require “g”
a = [1, 2, 3]
ga
require “g”     require “g” library

a = [1, 2, 3]
ga
require “g”     require “g” library

a = [1, 2, 3]
ga                and call “g”
Demo
How useful it is!
How to install
It’s very easy to install
           “g”
gem install g
That’s it
Thanks!
