NAME

ri − Ruby API reference front end

SYNOPSIS

ri [−ahilTv] [−d DIRNAME] [−f FORMAT] [−w WIDTH] [−-[no-]pager] [−-server[=PORT]] [−-[no-]list-doc-dirs] [−-no-standard-docs] [−-[no-]{system|site|gems|home}] [−-[no-]profile] [−-dump=CACHE] [name ...]

DESCRIPTION

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

ri is a part of Ruby.

name can be: It Class | Module | Module::Class

It Class::method | Class#method | Class.method | method

It gem_name: | gem_name:README | gem_name:History

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

A ‘.’ matches either class or instance methods, while #method matches only instance and ::method matches only class methods.

README and other files may be displayed by prefixing them with the gem name they’re contained in. If the gem name is followed by a ‘:’ all files in the gem will be shown. The file name extension may be omitted where it is unambiguous.

For example:

ri Fil
ri File
ri File.new
ri zip
ri rdoc:README

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

ri ’Array.[]’
ri compact\!

To see the default directories ri will search, run:

ri --list-doc-dirs

Specifying the −-system,−-site,−-home,−-gems, or −-doc-dir options will limit ri to searching only the specified directories.

ri options may be set in the RI environment variable.
