Give pry a Try
One of the things holding us back from developing on Ruby 1.9.3 has been ruby-debug. There are issues with installing and running it, and while they are manageable, it makes it such that (on a Rails projects with a Gemfile) every user needs to then use 1.9.3 and the unreleased ruby-debug19 version. Not fun.
So after many people suggested we try it, we gave pry a shot. I don’t know why we didn’t before; it is quick, easy, and allows a wide range of Ruby versions.
On a Rails project, your install is simple. In your
Gemfile remove anything related to
ruby-debug and add in
group :development, :test do
Then, anywhere you previously used
For example, we frequently have a cucumber step for invoking the debugger:
When 'I debug' do
It is a little different from ruby-debug, but we’re loving it so far!
Update: banisterfiend points out in the comments:
If you use `binding.pry` instead of just `pry` you’ll get access to all the locals at the point you call it, too :)
