NAME

ri1.9 - Ruby Information at your fingertips

SYNOPSIS

ri1.9 [options] [names...]

DESCRIPTION

ri1.9 displaies information on Ruby classes, modules, and methods. You can give the names of classes or methods to see their documentation. Partial names may be given: if the names match more than one entity, a list will be shown, otherwise details on that entity will be displayed.

Nested classes and modules can be specified using the normal Name::Name notation, and instance methods can be distinguished from class methods using "." (or "#") instead of "::".

For example:

     ri1.9 File
     ri1.9 File.new
     ri1.9 F.n
     ri1.9 zip
 

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

     ri1.9 'Array.[]'
     ri1.9 compact\!
 

OPTIONS

--classes, -c Display the names of classes and modules we know about.
--doc-dir, -d dirname A directory to search for documentation. If not specified, we search the standard rdoc/ri directories.
--format, -f name Format to use when displaying output: ansi, bs, html, plain, simple. Use 'bs' (backspace) with most pager programs. To use ANSI, either also use the -T option, or tell your pager to allow control characters. (for example using the -R option to less.)
--list-names, -l List all the names known to RDoc, one per line.
--no-pager, -T Send output directly to stdout.
--width, -w width Set the width of the output.
--version, -v Display the version of ri1.9.
--help, -h Display help.

Options may also be passed in the 'RI' environment variable
