Encouraging scientific hypothesizing and experimentation through interactive Ruby
NOTE: Heyruby is still in extreme infancy, so please refrain from
Tweeting or submitting anything anywhere until I can settle a few more things.

Good programmers are like scientists. When they want to answer a question They
form a hypothesis, then verify it with an experiment. Rubyists have the
experimentation phase down, but we tend not to hypothesize fully. This gem
helps people new to Ruby by prompting them for a hypothesis before returning the
result of their experiment.
This gem isn’t really meant to go in your Gemfile, it’s only utility is in
nagging you to think a bit harder.
Install it yourself as:
$ gem install heyruby
Got a question? Ask Ruby!
I wonder what the line %w[foo bar baz].map{ |s| s.split /[aeiou]/ }.flatten
does.
$ heyruby
Hey Ruby‽> %w[foo bar baz].map{ |s| s.split /[aeiou]/ }.flatten
What do you think the result of
```
%w[foo bar baz].map{ |s| s.split /[aeiou]/ }.flatten
```
will be? (Type . on a line by itself when done)
| I should get a single array containing the strings ["f", "b", "r", "b",
| "z"].
| .
Were you right?

When I was first learning Ruby in 2009 and 2010, my mental process for doing so
went along the lines of “Hey Ruby, what’s 2 + 2?”. This was so pervasive that
for some time I had alias heyruby='irb' in my bashrc. I hope that heyruby will
help people new to Ruby to gain the same comfort and casual familiarity with the
Ruby language that I have been developing since those early days.
