Ruby functions list

Ruby

Can anyone please suggest a webpage, e-book or a software where i could
just search a class or a method, for example gsub() and it would show an
explanation about that function and example.
Like in a BorlandC++ 3.1 pressing Ctrl+F1 will show help on current
operator and example.

Sorry for my grammatical skills, my english is not so good

What wrong with using ri ?

ri gsub

by default it will tell you each class that support a function and
then you can drill down i.e.

ri size

ri String.size
ri Array.size

to search up just a class, use
ri Array

imho the command line is a lot faster to lookup things vs switching to
a browser, searching for a bookmark then navigating to the website
with no search or poor search and then clicking on a link

for more help type
ri --help
