How to debug ruby tasks on Rubymine

Lets do an example creating a new task

First create a task file in your rails project, for example:

touch lib/tasks/debug.rake

And add one task in this file:

namespace :debug do
  desc 'Test rubymine debug feature'
  task :something => :environment do
    hello = 'world'

    p hello
  end
end

Now put a breakpoint on the line that we print the variable hello, and lets config the debugger.

To config the debugger, first go to menu "Run/Edit Configurations..." and add a new configuration using a rake template.

Example menu with arrows

Now fill the first field with you task name.

And now you're ready to debug, you just need to click on the bug button with your task selected.

It's a wonderful tool and you can use for solving problems in a "clean environment" and make sure your tasks works good.
