Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can email us for advice or just use some of the how-to screencasts on the site. This screencasting learning-path is a good place to start.

In many ways irb is to Ruby what IPython is to Python. Irb is a interactive shell for the Ruby language that allows you to test your code and make sure that you have the syntax and logic correct before it goes into your application.

In this video I will show you how to:

Use irb
Change the default prompt
Add tab completion

I give credit to whytheluckystiff for the config file and also to his guide to irb.

See additional information and the .irbrc file in the wiki(RubyLakeIrbCompletion).

Hi Eric. Thanks for updating the wiki entry with the extra information, I'm sure that'll be useful to new Ruby users.

I hope that we get more Ruby videos, it'll be a great resource for new coders to come see the differences (both positive and negative) between Ruby, Python and Perl.

Cheers!

Ian.

Johnny,

I found this site http://www.rubyweeklynews.org/20051023 and it says that on a Mac you need the .irbrc file to look like this:

require 'irb/completion'

ARGV.concat [ "--readline", "--prompt-mode", "simple" ]

I don't have a Mac to try it on but I hope that helps you. Please reply back here and let us know.

Johnny Thu, 11 Jan 2007 12:00

Hi there!

Thank you for this sexy prompt, very fine!

But I'm running OS X and in the Terminal after enabling tab completion in .irbrc when I hit tab the cursor still moves to the right one tab and nothing else happens... hmmm...

Any suggestions?

Kudos and Thanks for Eric
