An Elixir library for handling word inflections.

Getting Started

You can add Inflex as a dependency in your mix.exs file. Since it only requires Elixir and Erlang there are no other dependencies.

def deps do
  [
    {:inflex, "~> 2.0.0"}
  ]
end

If you are not using hex you can add the dependency using the GitHub repository.

def deps do
  [
    {:inflex, github: "nurugger07/inflex"}
  ]
end

Then run mix deps.get in the shell to fetch and compile the dependencies.

Requirements

Although Inflex supports Elixir 1.6, which is compatible with Erlang/OTP 19–20, Inflex requires Erlang/OTP 20+.

To incorporate Inflex in your modules, use import.

defmodule Blog do
  import Inflex

  def greeting(count), do: "You are the #{ordinalize(count)} visitor!"

end

Examples

Singularize & Pluralize

Here are some basic examples from iex:


iex(1)> Inflex.singularize("dogs")
"dog"

iex(2)> Inflex.pluralize("dog")
"dogs"

iex(3)> Inflex.singularize("people")
"person"

iex(4)> Inflex.pluralize("person")
"people"

Some other special cases are handled for nouns ending in -o and -y

iex(1)> Inflex.pluralize("piano")
"pianos"

iex(2)> Inflex.pluralize("hero")
"heroes"

iex(3)> Inflex.pluralize("butterfly")
"butterflies"

iex(4)> Inflex.pluralize("monkey")
"monkeys"

Inflect

iex(1)> Inflex.inflect("child", 1)
"child"

iex(2)> Inflex.inflect("child", 2)
"children"

Camelize & Pascalize

Inflex also camelizes or pascalizes strings and atoms.

iex(1)> Inflex.camelize(:upper_camel_case)
"UpperCamelCase"

iex(2)> Inflex.camelize("pascal-case", :lower)
"pascalCase"

Parameterize

Strings can be parameterized easily.

iex(1)> Inflex.parameterize("String for parameter")
"string-for-parameter"

iex(2)> Inflex.parameterize("String with underscore", "_")
"string_with_underscore"

Underscore

Makes an underscored, lowercase form from a string or atom.

iex(1)> Inflex.underscore("UpperCamelCase")
"upper_camel_case"

iex(2)> Inflex.underscore("pascalCase")
"pascal_case"

iex(3)> Inflex.underscore(UpperCamelCase)
"upper_camel_case"

iex(4)> Inflex.underscore(:pascalCase)
"pascal_case"
