# Configuration Groups

Codotype Generators may optionally expose additional configuration parameters that can be adjusted by end-users before producing code. A brief (albeit, incomplete) overview of the structures and patterns are outlined here.

# Structure

A ConfigurationGroup encapsulates a sub-set of a Generator's opt-in configuration. A Generator can expose any number of ConfigurationGroup definitions in it's codotype-generator.json file. A single ConfigurationGroup type is defined as follows:

{
  id: "DEPLOYMENT_CONFIGURATION_GROUP",
  label: "Deployment",
  identifier: "deployment",
  description: "Configure the deployment options for your app",
  type: "CONFIGURATION_GROUP_TYPE_OPTION",
  scope: "CONFIGURATION_GROUP_SCOPE_GLOBAL",
  more_info_url: "",
  attributes: ConfigurationOption[]
}

The ConfigurationOption type is defined thusly:

{
  label: "Deploy with Netlify?",
  identifier: "netlify",
  datatype: DATAYPE_BOOLEAN,
  help: "Include configuration files to automatically deploy your app to Netlify",
  more_info_url: "https://docs.netlify.com/configuration",
  icon: {
    type: "ICON_TYPE_URL",
    value: "https://netlify.com/logo.png"
  }
}

# Properties

The following properties describe a single ConfigurationGroup:

# id

The id property is a unique ID for the Attribute.

# label

The label property...

# identifier

The identifier property...

# description

The description property...

# type

The type property...

# scope

The scope property...

# more_info_url

The more_info_url property...

# description

The description property...

# attributes

The attributes property...

# Types

There are two different types of ConfigurationGroups - Options and Addons.

# Options

The OPTION type defines a 1-dimensional key-value store that can be represented as either a single instance scoped globally, or one unique instanced scoped to each Model/Schema.

# Addons

The ADDON type defines a 1-dimensional array of objects that can be represented as either a series of instances scoped globally, or one unique series of instances scoped to each Model/Schema.

# Scope

In addition to different ConfigurationGroup types, ConfigurationGroups also support a scope property, which can be set to either Global or Schema.

# Global Scope

The Global scope refers to configuration that's intended to be used to dictate generator-wide behavior. There can only ever be one value assigned to each attribute in a ConfigurationGroup whose scope is set to Global. Pairing this with the Option type is ideal scenarios like switching specific features on or off. Conversely, pairing it with the Addon type is ideal for scenarios where you want a user to be able to define multiple instances of your configuration object, each encapsulating values foe each attribute in the ConfigurationGroup.

For example, the above ConfigurationGroup will produce the following configuration at runtime when the scope is set to GLOBAL:

{
  configuration: {
    deployment: {
      netlify: true
    }
  }
}

# Schema Scope

Conversely, the above ConfigurationGroup will produce the following configuration when the scope is set to SCHEMA:

{
  configuration: {
    deployment: {
      movie: {
        netlify: true
      },
      director: {
        netlify: true
      }
    }
  }
}

The Schema scope refers to configuration that's intended to be used to dictate behavior specific to each Schema. This is ideal for things like choosing a unique icons or permissions for each Model.

# Default Options & Addons

TODO - this documentation is incomplete, pulled from Trello issue

The codotype-generator.json file should include a defaultAddons object that can provide optional defaults/examples for each ConfigurationGroup.

It should be built in such a way that Schemas with their source property set to generator will accept default Addons and Options.

It should also support a meta type such that all user-defined schemas (Schemas with source property set to user) will be supplied with the defaults when the configuration is built in the editor.

Note that we'll need to maintain whether or not these values are removable by the end-user in the editor.
