       PRY - A Reference to the PRY repl.


       pry  [--version]  [--exec]  [--no-pager]  [--no-history]  [--no-color] [-f] [--no-plugins]
       [--installed-plugins] [--simple-prompt] [--require file] [-I] [--context] [--help]


       Pry is a powerful alternative to the standard IRB shell  for  Ruby.  It  is  written  from
       scratch to provide a number of advanced features.



       -v --version
              Prints the version of Pry.

       -e --exec
              Executes argument in context before the session starts.

              Disable pager for long output.

              Disable history loading.

              Disable syntax highlighting for session.

       -f     Prevent loading of ~/.pryrc for session.

              Suppress loading of plugins.

              List installed plugins.

              Enable simple prompt mode (eg, >>).

       -r --require
              Require a ruby script at startup.

       -I     Add a path to the $LOAD_PATH

       -c --context
              Start the session in the specified context. Equivalent to context.pry in a session.


       ~/.pryrc Personal pry initialization


   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
           pry main:/Users/john $ shell-mode

   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 ..

       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.

           pry(Pry):1> show-method rep
