Habitat

Easily configure settings for Crystal projects

Installation

Add this to your application's shard.yml:

dependencies:
  habitat:
    github: luckyframework/habitat

Usage

require "habitat"

class MyServer
  Habitat.create do
    setting port : Int32
    setting debug_errors : Bool = true
    setting host : String, example: "127.0.0.1"
  end

  # Access them like this
  def start
    start_server_on port: settings.port
  end
end

MyServer.configure do |settings|
  settings.port = 8080
end

# At the very end of your program use this
# It will raise if you forgot to set any settings
Habitat.raise_if_missing_settings!

Settings can also be accessed from outside the class:

port = MyServer.settings.port
puts "The server is starting on port #{port}"
