_Ruby voyeurism_
_Get to the code_
Pry is a powerful alternative to the standard IRB shell for Ruby. It is
written from scratch to provide a number of advanced features, some of
these include:
* Syntax higlighting
* Navigation around state (`cd`, `ls` and friends)
* Runtime invocation
* Syntax highlighting
* Command shell integration
* Source code browsing (including core C source with the pry-doc gem)
* Documentation browsing
* Exotic object support (BasicObject instances, IClasses, ...)
* A Powerful and flexible command system
* Gisting ability
* Many convenience commands
* Ability to view and replay history
* Many convenience commands inspired by IPython and SLIME
Pry is a Ruby REPL (Read-Eval-Print-Loop) that specializes in the interactive
manipulation of objects during the running of a program.
In some sense it is the opposite of IRB in that you bring a REPL
session to your code (with Pry) instead of bringing your code to a
REPL session (as with IRB).
It is not based on the IRB codebase, and implements some unique REPL
commands such as `show-method`, `show-doc`, `ls` and `cd` (type `help`
to get a full list).
Pry is also fairly flexible and allows significant user
[customization](http://rdoc.info/github/banister/pry/master/file/wiki/Customizing-pry.md). It
