Deordinalize

A small package to “deordinalize” strings into the integers they reference. Ported from Jeremy Ruppel’sdeordinalize Ruby gem.

Installation:

The package can be installed by adding deordinalize to your list of dependencies in mix.exs:

def deps do
  [
    {:deordinalize, "~> 0.1.1"}
  ]
end

Usage:

Deordinalize, for the time being, only supports ordinals from 1 to 100.

We can deordinalize numeric ordinals:

    "1st" |> Deordinalize.to_integer   # => 1
    "11th" |> Deordinalize.to_integer  # => 11
    "99th" |> Deordinalize.to_integer  # => 99

Or we can deordinalize more verbose ordinals:

    "first" |> Deordinalize.to_integer         # => 1
    "eleventh" |> Deordinalize.to_integer      # => 11
    "ninety-ninth" |> Deordinalize.to_integer  # => 99

Use to_index to get the zero-based index of your ordinal:

    "first" |> Deordinalize.to_integer!         # => 0
    "eleventh" |> Deordinalize.to_integer!      # => 10
    "ninety-ninth" |> Deordinalize.to_integer!  # => 98
