ri


SYNOPSIS
       ri1.8 [options] [names...]

DESCRIPTION
       ri1.8 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:
           ri1.8 File
           ri1.8 File.new
           ri1.8 F.n
           ri1.8 zip

       Note that shell quoting may be required  for  method  names  containing
       punctuation:
           ri1.8 'Array.[]'
           ri1.8 compact\!
