pry |
Pry is an interactive shell for the Ruby programming language. It is notable for its Smalltalk-inspired [1] ability to start a REPL within a running program. This lets programmers debug and modify the current state of a system.
Pry exposes most of its introspective capabilities using a
filesystem metaphor.
[2] For example, it has a
cd
command to start interacting with a particular object, and uses
ls
to list
methods and
variables.
It is possible to start Pry at any point inside a running program. [3] Due to the reflective nature of Ruby, this lets the programmer inspect the program, change its current state, or correct the source code without restarting the process.
A number of third party plugins are available for Pry, [1] these add tighter integration with other Ruby projects, enhance the abilities of Pry itself, and make Pry available over a remote connection.
