Installation

Gem dependencies

Sublime Debugger relies on two seperate gems for diffirent ruby versions. For Ruby 1.9.3 you need the debugger gem, which can be installed using

gem install debugger
, and for Ruby 2.0.0 you need the byebug gem, which can be installed using
gem install byebug
.

Unsupported ruby versions

I cannot test this against all ruby versions, so I only explicity support Ruby 1.9.3 and Ruby 2.0.0. RVM is a good way to have multiple ruby versions installed at once and switch between them when debugging or running normally. Sublime Debugger will use the ruby version that you set as default, so you must set either Ruby 1.9.3 or Ruby 2.0.0 as the default. Remember to reinstall the byebug or debugger gem when you change ruby versions, or else you will get an

Connection could not be made: [Errno ##] Connection refused
error.

If you need to have your ruby program running with an unspported ruby version you can manually add the version to the supported versions list. In the package's directory, which you can get to by going to

preferences -> browse packages
in sublime text and then opening the
Ruby Debugger
folder, there is a
ruby_version_discoverer.rb
file where you can add your ruby version.

Package Control

Execute "Package Control: Install Package" in the Command Pallette to retrieve a list of available packages. Search in the list and install package

Ruby Debugger
.

Git

Clone the repository by executing the following command in your Packages directory:

git clone https://github.com/shuky19/sublime_debugger.git "Ruby Debugger"

Download

Get the latest source from GitHub and extract the source into your Packages directory to a folder named "Ruby Debugger".

Note: You can locate your Packages directory in the menu under

Preferences / Browse Packages...

Troubleshoot

Why do I get
Connection could not be made: [Errno 61] Connection refused
in the output window?

Well, Most of the reasons for this error come from environmental problems, following the steps below will help you fix it:

  • Enable logging: preferences -> Package Settings -> Ruby Debugger -> Settings - Default (you can use User as well)
  • Run you ruby on a shell and make sure it runs perfectly.
  • From that shell run
    which ruby
    and
    ruby --version
  • Run the debugger and compare its output to yours
  • Figure out whether your ruby path comes from a different ruby environment (rbenv | rvm | custom executable)
  • Figure out whether your ruby default version is not set appropriately

Why do I get
Errno::EADDRINUSE: Address already in use - bind(2)
in the output window?

Either because there is another process running which is using ports 8989/8990 or the last debugger process is still alive (

killall ruby
will solve that).
