Builder is a creational design pattern that lets you construct complex objects step by step. The pattern allows you to produce different types and representations of an object using the same construction code.
Imagine a complex object that requires laborious, step-by-step initialization of many fields and nested objects. Such initialization code is usually buried inside a monstrous constructor with lots of parameters. Or even worse: scattered all over the client code.
In most cases most of the parameters will be unused, making the constructor calls pretty ugly. For instance, only a fraction of houses have swimming pools, so the parameters related to swimming pools will be useless nine times out of ten.
Some of the construction steps might require different implementation when you need to build various representations of the product. For example, walls of a cabin may be built of wood, but the castle walls must be built with stone.
In this case, you can create several different builder classes that implement the same set of building steps, but in a different manner. Then you can use these builders in the construction process (i.e., an ordered set of calls to the building steps) to produce different kinds of objects.
For example, imagine a builder that builds everything from wood and glass, a second one that builds everything with stone and iron and a third one that uses gold and diamonds. By calling the same set of steps, you get a regular house from the first builder, a small castle from the second and a palace from the third. However, this would only work if the client code that calls the building steps is able to interact with builders using a common interface.
You can go further and extract a series of calls to the builder steps you use to construct a product into a separate class called director. The director class defines the order in which to execute the building steps, while the builder provides the implementation for those steps.
In addition, the director class completely hides the details of product construction from the client code. The client only needs to associate a builder with a director, launch the construction with the director, and get the result from the builder.
This example of the Builder pattern illustrates how you can reuse the same object construction code when building different types of products, such as cars, and create the corresponding manuals for them.
A car is a complex object that can be constructed in a hundred different ways. Instead of bloating the Car class with a huge constructor, we extracted the car assembly code into a separate car builder class. This class has a set of methods for configuring various parts of a car.
If the client code needs to assemble a special, fine-tuned model of a car, it can work with the builder directly. On the other hand, the client can delegate the assembly to the director class, which knows how to use a builder to construct several of the most popular models of cars.
Say you have a constructor with ten optional parameters. Calling such a beast is very inconvenient; therefore, you overload the constructor and create several shorter versions with fewer parameters. These constructors still refer to the main one, passing some default values into any omitted parameters.
The base builder interface defines all possible construction steps, and concrete builders implement these steps to construct particular representations of the product. Meanwhile, the director class guides the order of construction.
The Builder pattern lets you construct products step-by-step. You could defer execution of some steps without breaking the final product. You can even call steps recursively, which comes in handy when you need to build an object tree.
Builder focuses on constructing complex objects step by step. Abstract Factory specializes in creating families of related objects. Abstract Factory returns the product immediately, whereas Builder lets you run some additional construction steps before fetching the product.

The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming. The builder pattern separates the construction of a complex object from its representation. It is one of the 23 classic design patterns described in the book Design Patterns (often referred to as the "Gang of Four" or simply "GoF") and is sub-categorized as a creational pattern.[1]
Creating and assembling the parts of a complex object directly within a class is inflexible. It commits the class to creating a particular representation of the complex object and makes it impossible to change the representation later independently from (without having to change) the class.
The intent of the Builder design pattern is to separate the construction of a complex object from its representation. By doing so, the same construction process can create different representations.[1]
In the above UML class diagram, the Director class doesn't create and assemble the ProductA1 and ProductB1 objects directly.Instead, the Director refers to the Builder interface for building (creating and assembling) the parts of a complex object,which makes the Director independent of which concrete classes are instantiated (which representation is created).The Builder1 class implements the Builder interface by creating and assembling the ProductA1 and ProductB1 objects.
The UML sequence diagram shows the run-time interactions: The Director object calls buildPartA() on the Builder1 object, which creates and assembles the ProductA1 object.Thereafter, the Director calls buildPartB() on Builder1, which creates and assembles the ProductB1 object.
Builder is a visual development tool. It shortens plugin development time by automating common development tasks and makes programming fun again. With Builder you can create a fully functional plugin scaffold in a matter of minutes.
Builder implements a Rapid Application Development process that automates the boring activities without sacrificing complete control. With this tool you can spend more time implementing the plugin's business logic in your favorite code editor rather than dealing with the more mundane tasks, like building forms or managing plugin versions.
Put simply, you can create a multilingual plugin, that installs database tables, has backend lists and forms protected with user permissions, and adds CMS pages for displaying data managed with the plugin. After learning how Builder works, this process takes just a few minutes.
Builder is a productivity tool, it doesn't completely replace coding by hand and doesn't include a code editor for editing PHP files (the only exception is the version management interface). Builder never overwrites or deletes plugin PHP files, so you can rest assured knowing that the code you write never gets touched by Builder. However, Builder can create new PHP files, like models and controllers.
Most of the visual editors in Builder work with YAML configuration files, which are a native concept in October CMS. For example, after creating a model class in Builder, you can choose to add a form to the model. This operation creates a YAML file in the model's directory.
Before you create your first plugin with Builder you should configure it. Open the Settings page in October CMS backend and find Builder in the side menu. Enter your author name and namespace. The author name and namespace are required fields and should not change if you wish to publish your plugins on October CMS Marketplace.
On the Builder page in October CMS backend click the small arrow icon in the sidebar to expose the plugin list. After clicking the "Create plugin" button, enter the plugin name and namespace. The default author name and namespace can be pre-filled from the plugin settings. Select the plugin icon, enter the description text and plugin homepage URL (optional).
Every time when you save changes in a table, Builder shows a popup window with the automatically generated migration PHP code. You can't edit the code in the popup, but you can inspect it or copy to the clipboard. After reviewing the migration, click Save & Apply button. Builder executes the migration immediately and saves the migration file to the plugin's updates directory. Afterwards you can find all plugin migrations on the Versions tab of Builder.
Important: Although Builder generates migration files automatically, it can't prevent data loss in some cases when you significantly change the table structure. In some cases it's possible - for example, when you alter length of a string column. Always check the migration PHP code generated by Builder before applying the migration and consider possible consequences of running the migration in a production database.
Currently Builder doesn't allow to manage table indexes with the visual user interface. Unique column management is not supported yet as well. Please use the Version Management feature to manually create migration files.
Please note that you cannot delete model files with builder because it would contradict the idea of not deleting or overwriting PHP files with the visual tool. If you need to delete a model, remove its files manually.
Forms in October CMS are defined with YAML files. The default form file name is fields.yaml. In the Form Builder, click a placeholder and select a control from the popup list. After that you can click the control and edit it parameters in Inspector.
