# Cantare [![Build Status](https://travis-ci.com/vincentvanbush/cantare.svg?branch=master)](https://travis-ci.com/vincentvanbush/cantare)

Declarative action authorization library for Elixir, inspired by [CanCanCan](https://github.com/ryanb/cancan).

Provide simple ability rules for your application using idiomatic Elixir patterns, just like this:

```

defmodule YourApp.Abilities do

  import Cantare.Abilities

  alias YourApp.Schemas.User

  alias YourApp.Schemas.{Item, Post}

  use Cantare.Abilities, repo: YourApp.Repo

  def abilities(User) do

    User

    |> can(:show, Item, fn %User{} = user, %Item{} = item -> item.active end)

    |> can(:edit, Post, fn %User{} = user, %Post{} = post -> Ecto.DateTime.compare(post.created_at, user.created_at) == :gt end)

    |> can(:create, League, fn current_user -> [name: current_user.email] end)

  end

end

```

Further README steps coming soon... This is still a very work-in-progress library that has _just_ been separated out of a private project from which it originated. There is still plenty of problems to resolve - perhaps most importantly, it still needs to be adapted to Ecto 3.

Stay tuned!

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed

by adding `cantare` to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:cantare, "~> 0.1.0"}

  ]

end

```

Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)

and published on [HexDocs](https://hexdocs.pm). Once published, the docs can

be found at [https://hexdocs.pm/cantare](https://hexdocs.pm/cantare).
