Intro to Reading Ruby Doc: What's M, C, ::, # ?

,

This page is a guide to reading Ruby's official doc, for Ruby beginners.

Ruby Doc home page is at http://ruby-doc.org/

On top, you can see {Core, Std-lib, Gems}. These are most important.

For beginner, you'd be concerned with the Core and Std-lib.

Now, look at the Ruby Core doc page: http://ruby-doc.org/core-1.9.3/. The left side are classes. The right side are methods.

On the left side, the classes, some have a gray “C” some have “M”.

This means, for beginner, you can probably ignore all those M ones.

On the right side, are methods, with :: or #.
