Walk the stack in a Pry session
pry-stack_explorer is a plugin for the Pry REPL that enables the user to navigate the call-stack.
From the point a Pry session is started, the user can move up the stack through parent frames, examine state, and even evaluate code.
ruby-debug, pry-stack_explorer incurs no runtime cost and
enables navigation right up the call-stack to the birth of the
pry-stack_explorer is currently designed to work on Rubinius and MRI Ruby 1.9.2+ (including 1.9.3). Support for other Ruby versions and implementations is planned for the future.
show-stack commands are provided. See
Pry's in-session help for more information on any of these commands.
How to use:
pry-stack_explorer, just start Pry as normal (typically via a
binding.pry), the stack_explorer plugin will be detected and used automatically.
- Install the gem:
gem install pry-stack_explorer
- Read the documentation
- See the source code
- See the wiki for in-depth usage information.
Example: Moving around between frames
Example: Modifying state in a caller
Output from above is
goodbye as we changed the
x local inside the
alpha (caller) stack frame.
- First release, so may have teething problems.
- Limited to Rubinius, and MRI 1.9.2+ at this stage.
