       displayed.

OPTIONS

       -p, --printer=printer
	      Select a printer:
		flat - Prints a flat profile as text (default).
		graph - Prints a graph profile as text.
		graph_html - Prints a graph profile as html.
		call_tree - format for KCacheGrind

       -m, --min_percent=min_percent
	      The minimum percent a method must take before being included in output reports.  This option is not supported for call tree.

       -f, --file=path
	      Output results to a file instead of standard out.

       --mode=measure_mode
	      Select what ruby-prof should measure
		process - Use process time (default).
		wall - Use wall time.
		cpu - Use the CPU clock counter (only supported on Pentium and PowerPCs).

       --replace-progname

NAME

     irb -- Interactive Ruby Shell

SYNOPSIS

     irb [--version] [-dfm] [-I directory] [-r library] [--[no]inspect] [--[no]readline] [--prompt mode] [--prompt-mode mode] [--inf-ruby-mode]
	 [--simple-prompt] [--noprompt] [--tracer] [--back-trace-limit n] [--irb_debug n] [--] [program_file] [argument ...]

DESCRIPTION

     irb is the REPL(read-eval-print loop) environment for Ruby programs.

OPTIONS

     --version	    Prints the version of irb.

     -E external[:internal]
     --encoding external[:internal]
		    Same as `ruby -E' .  Specifies the default value(s) for external encodings and internal encoding. Values should be separated
		    with colon (:).

		    You can omit the one for internal encodings, then the value (Encoding.default_internal) will be nil.

     -I path	    Same as `ruby -I' .  Specifies $LOAD_PATH directory

     -U 	    Same as `ruby -U' .  Sets the default value for internal encodings (Encoding.default_internal) to UTF-8.

     -d 	    Same as `ruby -d' .  Sets $DEBUG to true.

     -f 	    Suppresses read of ~/.irbrc.

     -h
     --help	    Prints a summary of the options.

     -m 	    Bc mode (load mathn, fraction or matrix are available)

     -r library     Same as `ruby -r'.	Causes irb to load the library using require.

     --inspect	    Uses `inspect' for output (default except for bc mode)

     --noinspect    Doesn't use inspect for output

     --readline     Uses Readline extension module.

     --noreadline   Doesn't use Readline extension module.

     --prompt mode
     --prompt-mode mode
		    Switch prompt mode. Pre-defined prompt modes are `default', `simple', `xmp' and `inf-ruby'.

     --inf-ruby-mode
		    Uses prompt appropriate for inf-ruby-mode on emacs.  Suppresses --readline.

     --simple-prompt
		    Makes prompts simple.

     --noprompt     No prompt mode.

     --tracer	    Displays trace for each execution of commands.

     --back-trace-limit n
		    Displays backtrace top n and tail n.  The default value is 16.

     --irb_debug n  Sets internal debug level to n (not for popular use)

ENVIRONMENT

     IRBRC

     Also irb depends on same variables as ruby(1).

FILES

     ~/.irbrc	     Personal irb initialization.

EXAMPLES

	   % irb
	   irb(main):001:0> 1 + 1
	   2
	   irb(main):002:0> def t(x)
	   irb(main):003:1> x+1
	   irb(main):004:1> end
	   => nil
	   irb(main):005:0> t(3)
	   => 4
	   irb(main):006:0> if t(3) == 4
	   irb(main):007:1> p :ok
	   irb(main):008:1> end
	   :ok
	   => :ok
	   irb(main):009:0> quit
