Introduction

This gem defines ordinal methods first, second, third ... ninth, tenth & last for retrieving values from strings. Ruby Core already includes a Array#first and Array#last so only second, third ... ninth & tenth have been added to the Array class.

With arrays

arr = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j"]

arr.second     #=> "b"
arr.third      #=> "c"
arr.fourth     #=> "d"
arr.fifth      #=> "e"
arr.sixth      #=> "f"
arr.seventh    #=> "g"
arr.eighth     #=> "h"
arr.ninth      #=> "i"
arr.tenth      #=> "j"

With strings

str = "abcdefghij"

str.first      #=> "a"
str.first(2)   #=> "ab"

str.second     #=> "b"
str.third      #=> "c"
str.fourth     #=> "d"
str.fifth      #=> "e"
str.sixth      #=> "f"
str.seventh    #=> "g"
str.eighth     #=> "h"
str.ninth      #=> "i"
str.tenth      #=> "j"

str.last       #=> "j"
str.last(3)    #=> "hij"

When n> str.length, last(n) mimics the behaviour of Array#last by returning str:

str.last(11)   #=> "abcdefghij"

To Do List

• Update gem to work for > tenth < last.

Notes

• gem versions 0.0.2 to 0.0.5 may have gemspec dates slightly out by a few days. Just omitted to update the date before builds. Has no bearing on functionality.
