You can run ri from inside IRB if you do this:

def ri(*args)
  RDoc::RI::Driver.run(args)
end

Now you can do

> ri 'String.length'

So today I learned, sort of by accident, how to wrap any number of strokes into their separate li html elements.

I use Sublime editor. In there I pressed Ctrl+Shift+p (command pallete) and typed ‘wrap’ and found Emmet’s ‘Wrap with Abbreviation’ function.

At first I just tried ul>li*5. That wasn’t what I wanted. I just thought how could I get to the result I wanted when I started backspacing and when 5 was removed I was left with **ul>li * ** it worked. Good think I noticed. Saved some precious time on googling that stuff.

Gosh, I got so excited.

While you cannot run ri commands from inside an irb session, you can run ri commands from inside a pry session.

What are ri, irb and pry?

ri:
I have seen different (very talented) people saying that it’s abbreviated from different terms, like Ruby Information, Ruby Interactive and Ruby Index. No matter which term it stands for, it’s the Ruby tool for navigating documentation.

irb:
Interactive Ruby Shell is a REPL for Ruby.

pry:
A runtime developer console and IRB alternative with powerful introspection capabilities (as stated on its Github page). Installable as a Gem.
