Defined in:

#snakecase ⇒ Object Also known as: underscore

Underscore a string such that camelcase, dashes and spaces are replaced by underscores. This is the reverse of #camelcase, albeit not an exact inverse.

"SnakeCase".snakecase         #=> "snake_case"
"Snake-Case".snakecase        #=> "snake_case"
"Snake Case".snakecase        #=> "snake_case"
"Snake  -  Case".snakecase    #=> "snake_case"

Note, this method no longer converts ‘::` to `/`, in that case use the #pathize method instead.
