Eno

Lightweight SQL toolkit for elixir inspired by yesql and ragtime.

For the moment only PostgreSQL is supported, and you need to add postgrex as a dependency.

Installation

It’s available in Hex, the package can be installed as:

1. Add eno to your list of dependencies in mix.exs:

   def deps do

    [{:eno, "~> 0.0.1"}]

   end

Usage

lib/yourapp/repo.ex

defmodule YourApp.Repo do
  use Eno
end

lib/yourapp/repo.sql

-- name: user_list
select * from users offset :offset limit :limit;

-- name: user_get
select * from users where user_id = :id;

lib/yourapp.ex

children = [
  worker(YourApp.Repo, []),
]

config/config.ex

config :eno, YourApp.Repo,
  adapter: Eno.Adapters.Postgres,
  hostname: "localhost",
  username: "user",
  password: "pass",
  database: "db"

finally

iex> YourApp.Repo.user_list offset: 0, limit: 10

iex> YourApp.Repo.user_get 1

priv/migrations/repo/20160507022535_init_users.down.sql

drop table users;

config/config.ex

config :yourapp,
  eno_repos: [YourApp.Repo]
