irb
IRB(1) Ruby Programmers Reference Guide IRB(1)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
