Using MRI? We recommend pry-byebug instead!


A simple execution control add-on for Pry.

Compatible with JRuby >=

Teaches Pry about step, next, and continue to create a simple debugger.

To use, invoke pry normally:

def some_method
  binding.pry          # Execution will stop here.
  puts 'Hello, World!' # Run 'step' or 'next' in the console to move here.

When using JRuby, you also need to run it with the --debug flag. You can also add the flag to your JRUBY_OPTS environment variable for it to apply when running any ruby command, but do note that even when not making use of pry this has a big impact on JRuby performance.

pry-nav is not yet thread-safe, so only use in single-threaded environments.

Rudimentary support for pry-remote (>= 0.1.1) is also included. Ensure pry-remote is loaded or required before pry-nav. For example, in a Gemfile:

gem 'pry'
gem 'pry-remote'
gem 'pry-nav'

Stepping through code often? Add the following shortcuts to ~/.pryrc:

Pry.commands.alias_command 'c', 'continue'
Pry.commands.alias_command 's', 'step'
Pry.commands.alias_command 'n', 'next'

Please note that debugging functionality is implemented through set_trace_func, which imposes a large performance penalty.
