Simple execution control in Pry
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. end
pry-nav is not yet thread-safe, so only use in single-threaded environments.
Rudimentary support for pry-remote 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'
Debugging functionality is implemented through
set_trace_func, which imposes a large performance
penalty. pry-nav traces only when necessary, but due to a workaround for a
bug in 1.9.2, the console will feel sluggish. Use 1.9.3 for best
results and almost no performance penalty.
