EXAMPLES
Basic Usage
$ pry
[1] pry(main)>4 + 5
=> 9
[2] pry(main)> def hello_world
[2] pry(main)* puts "Hello, World!"
[2] pry(main)* end
=> nil
[3] pry(main)> hello_world
Hello, World!
=> nil
Command Line Interaction
Prefix any command you want your shell to execute with a period and pry will return the results from your
shell.
[1] pry(main)> .date
Fri Nov 11 09:52:07 EST 2011
On the command line enter shell-mode to incorporate the current working directory into the Pry prompt.
pry(main)> shell-mode
pry main:/Users/john/ruby/projects/pry $ .cd ..
pry main:/Users/john/ruby/projects $ .cd ~
pry main:/Users/john $ .pwd
/Users/john
pry main:/Users/john $ shell-mode
pry(main)>
State Navigation
The cd command is used to move into a new object (or scope) inside a Pry session. When inside the new
scope it becomes the self for the session and all commands and methods will operate on this new self.
pry(main)> self
=> main
pry(main)> cd Pry
pry(Pry):1> self
=> Pry
pry(Pry):1> cd ..
pry(main)>
The ls command is essentially a unified wrapper to a number of Ruby´s introspection mechanisms, including
(but not limited to) the following methods: methods, instance_variables, constants, local_variables,
instance_methods, class_variables and all the various permutations thereof.
By default typing ls will return a list of just the local and instance variables available in the current
context.
• The -M option selects public instance methods (if available).
• The -m option selects public methods.
• The -c option selects constants.
• The -i option select just instance variables.
• The -l option selects just local variables.
• The -s option modifies the -c and -m and -M options to go up the superclass chain (excluding Object).
• The --grep REGEX prunes the list to items that match the regex.
Source Browsing
Simply typing show-method method_name will pull the source for the method and display it with syntax
highlighting. You can also look up the source for multiple methods at the same time, by typing
show-method method1 method2. As a convenience, Pry looks up both instance methods and class methods using
this syntax, with priority given to instance methods.
