Upgraded Laravel Generator Command

This is a very simple package, with one single goal: to create Artisan Commands, which generate files based on stubs.

It allows you to create a single file, or several files in one go. For example when creating a CRUD Controller, you might want to generate the controller, the model, the migration, the factory, the seeder and all the views in one go.

The Generator Command offered by Laravel is good enough for simple files, but is poorly documented and lacks some basic options, which I needed in most of my projects. After writing a few generator commands for my packages, I decided to extract this into a simple package. If you feel like contributing, please fork the repository and submit a PR.

Installation

Via composer import:

Usage

Step 1: Create the command

The package comes with an artisan generator command to generate a generator command (sounds a bit recursive, and it is) in your project:

This will create a new command in your app/Console/Commands folder.

The new command class inherits the abstract AntonioPrimera\Artisan\FileGeneratorCommand and contains a ToDo list and some commented recipe samples to get you inspired and started as fast as possible.

The FileGeneratorCommand extends the default Laravel Console Command, so you need to provide a signature and optionally a description. The signature should have a {name} parameter, to get the target file name from the console input. If you want to preserve the stub file names, you can omit the {name} parameter (this acts like a publish command).

e.g.

Step 2: Implement the recipe method in the command

Implement the abstract recipe() method in your generator command. This method should return a FileRecipe instance, a predefined Recipe instance (all of them inherit the FileRecipe) or an array of Recipe instances.

e.g

Note: If you want more control over the command, you can take matters into your own hands and override the handle() method and use the FileRecipe class directly.

File recipe fluent interface

While in previous versions, recipes were created as associative arrays or simple constructor calls, but this was not ideal, because it was hard to remember all the available attributes and their names. Now, the fluent interface allows for a more readable and flexible recipe definition. The only 2 mandatory attributes are the stub and the target folder. All other attributes are optional.

For example, to create a recipe for a json file, you could use the following code:

All methods of the fluent interface are prefixed with with and the attribute name in camel case, and are all chainable.

withStub(string|File|Stub $stub)

This is the path pointing to the stub file. If an absolute path is given, the given path is used, without any modifications. If the given path is relative, it is considered to be a path relative to the project root.

This attribute is mandatory for any recipe.

withTargetFolder(string|Folder $target)

This is the target root folder for the generated files. If this is an absolute path, the given path is used. If this is a relative path, it is considered to be a path relative to the project root.

This attribute is mandatory for any recipe.

Note: this is not the final folder where the file will be generated, but the root folder for the target file. The final folder will be determined by this target folder (set using this method) and the relative path to the target file, which is inferred from the command argument.

e.g. if the target folder is Http/Controllers/Site and the command will be called with the argument SectionControllers/Guest/HeroSection, the final target folder will be app/Http/Site/SectionControllers/Guest (and the file name will be HeroSection.php).

withRootNamespace(string|null $rootNamespace)

This attribute is only relevant for generating php classes from stubs having the placeholder DUMMY_NAMESPACE. The final namespace will be determined by the root namespace and the relative path to the target file.

The default rootNamespace value is 'App', but this is in most cases not a relevant setting. Maybe in future versions, this will be inferred from the composer.json file automatically, but for now, you should set this manually.

e.g. if the root namespace is App\Http\Controllers\Site, and the command will be called with the argument SectionControllers/Guest/HeroSection, the final namespace will be App\Http\Controllers\Site\SectionControllers\Guest.

withExtension(string|null $extension)

By default, the extension is inferred from the stub file. It is recommended that the stub file has a .stub extension after the desired target extension

(e.g. sampleFile.blade.php.stub). The .stub extension is removed when guessing the target extension, so you don't have to provide an extension in the recipe.

If the target extension shouldn't (or can't) be inferred from the stub file, you can use this recipe attribute to set it. If a string is given, it will just be appended as an extension to the target file. If you want to generate a file without any extension, use an empty string.

e.g. 'extension' => 'blade.php';

withScope(string|null $scope)

This attribute is optional and useful just for the console output. It will be displayed in the console output, when the command is run, to give the user a hint about the scope of the generated file.

e.g. $recipe->withScope('View Component')

withReplace(array $replace)

This optional attribute should receive an associative array of placeholder => replace_with items. This will replace all placeholders in the stub files with the corresponding values.

By default, the generator command replaces 2 placeholders: DUMMY_CLASS and DUMMY_NAMESPACE. You can override these 2 default items with values of your own, but in most cases, these should work fine. If your generate a class or some file with a namespace, you should use the withRootNamespace(...) method.

e.g. $replace = ['GENERATED_BY' => 'Antonio Primera', 'GENERATED_ON' => now()->format('d.m.Y H:i:s')]

withDefaultReplacements(array $defaultReplace)

This optional attribute should receive an associative array of placeholder => replace_with items. This will be used as a set of default replacements, which can be overridden by the replacements provided to the withReplace(...) method.

This is useful if you want to create reusable recipes, which should have some default replacements, but can be overridden by the command, which uses the recipe.

withFileNameTransformer(mixed $transformer)

This attribute should contain a callable or the name of a static method from the Illuminate\Support\Str helper class (e.g. 'kebab' / 'snake' etc.). The callable will receive the target file name as an argument and should return the desired file name.

If not provided, this attribute is null and will not change the file name in any way.

e.g. if you want to generate a migration file (without using the predefined migration recipe), you could use the following transformer:

withRelativePathTransformer(mixed $transformer)

This attribute is optional and should contain a callable, which receives the relative path to the target file as an argument and returns the desired relative path. This is useful if you want to change the target folder structure based on the target file name.

For example, if you want to generate a blade file, you would probably want to transform the relative path to the target into kebab case, so that the view can be addressed in a dot notation with kebab case view name and path.

Note: The relative path is the path inferred from the command argument, so for example, if the command argument is SiteComponents/Sections/HeroSection, the relative path will be SiteComponents/Sections and the target file name will be HeroSection.

Hooks

beforeFileCreation()

You can override this hook in your command, to run any code after the recipe is created, but before generating the files, according to the recipe.

afterFileCreation()

You can override this hook in your command, to run any code after all files from the recipe were successfully generated. The hook receives a flag, whether the command was run in test mode (Dry Run), a list of absolute paths for all generated files and the recipe used to generate the files.

cleanupAfterError()

This hook will run in case an error occurs during file generation and by default removes all the files generated by the command until the error occurred (an Exception was thrown).

You can override this hook in your command, to run any code in case an exception was thrown during file generation.

Advanced usage

What if I want another command parameter to hold the target file name?

If for any reason, you want to use another command parameter to hold the target file name, you can override the default protected string $nameArgument = 'name'; attribute of the command (but in most cases you shouldn't).

Upgrade Guide
