NAME


ri — Ruby API reference front end

SYNOPSIS


ri [-Ti] [-d directory] [-f format] [--list-doc-dirs] [--no-standard-docs]
[--[no-]{system|site|gems|home}] [--[no-]use-cache] [--width=width] [target ...]

DESCRIPTION


ri is a CLI front end for the Ruby API reference. You can search and read API reference for
classes and methods with ri.

ri is a part of Ruby.

target can be one of the following forms:

Class for classes

Class::method for class methods

Class#method for instance methods

Class.method for both class and instance methods

method for both class and instance methods

All class names may be abbreviated to their minimum unambiguous form. If a name is
ambiguous, all valid options will be listed.

For example:

ri Fil
ri File
ri File.new
ri zip

Note that shell quoting may be required for method names containing punctuation:

ri 'Array.[]'
ri compact

OPTIONS


--version Prints the version of ri.

-T
--no-pager Send output directly to stdout, rather than to a pager.

-d directory
--doc-dir=directory
List of directories from which to source documentation in addition to the
standard directories. May be repeated.

-f FORMAT
--fmt FORMAT
--format=FORMAT
Format to use when displaying output:

ansi, bs, html, plain, simple

Use 'bs' (backspace) with most pager programs. To use ANSI, either disable
the pager or tell the pager to allow control characters.

-i
--interactive This makes ri go into interactive mode.

When ri is in interactive mode it will allow the user to disambiguate lists
of methods in case multiple methods match against a method search string. It
also will allow the user to enter in a method name (with auto-completion, if
readline is supported) when viewing a class.

--list-doc-dirs
List the directories from which ri will source documentation on stdout and
exit.

--no-standard-docs
Do not include documentation from the Ruby standard library, site_lib,
installed gems, or ~/.rdoc.

--no-home.

--[no-]site Include documentation from libraries installed in site_lib. Defaults to
