Screencast Scripting

Last week I posted a short screencast to show some features of ActiveSupport::Multibyte. After typing through the entire screencast twice I decided to automate the process. Screenager, the automated screencast typer, was born.

You can download Screenager from my personal Subversion repository, you will also need a recent version of ActiveSupport.

svn export https://dwerg.net/svn/screenager/trunk screenager
cd screenager
svn export --force http://svn.rubyonrails.org/rails/trunk/activesupport/lib
./screenager --speed 2 http://www.fngtps.com/2006/10/activesupport.rb

The version currently in SVN evaluates the Ruby code with eval using a clean binding every time you start a new screenplay. I really wanted to use the Freaky Freaky Sandbox for this, but it’s in heavy development and didn’t run at all when I was coding this. Sandbox and multiline Ruby statements are planned for future versions.
