ri1.9 - Ruby Information at your fingertips
ri1.9 [options] [names...]
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\!
--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 April 2005 ri1.9(1)
