Mage2Gen

Mage2Gen is a python library for generating Magento 2 modules. It is build to be extendable with snippets for creating more complex Magento 2 modules based on simple input.

Installation

To install the Python library and the command line utility, run:

sudo pip3 install mage2gen

Interactive command line

With the mage2gen command line tool you can interactively create and generate Magento 2 modules. If you have installed mage2gen for your whole system you can start it by running mage2gen. You will be asked to give the module a package name, name and description:

bash> mage2gen
Package name [Mage2gen]: Mage2gen
Module name: Test
Description: A Mage2Gen test module

Type help or ? to list commands.
(Mage2Gen)

Help

You can use help or ? to show all available commands and help <command> to show command specific help descriptions:

(Mage2Gen) help

Documented commands (type help <topic>):
========================================
add  exit  generate  help  info  list  remove

Undocumented commands:
======================
EOF

(Mage2Gen) help add
Add a snippet to the module

List snippets

With the list command you get a list of all the available snippets you can add to your module:

(Mage2Gen) list
console cronjob controller system plugin shipping install language observer payment

Add snippet

To add a snippet you can use the add <snippet name> command, you can auto-complete a snippet name with TAB:

(Mage2Gen) add console
Action name*: test
Short description*: Test log command

Show added snippets

When you have added multiple snippets and you want to see which snippets are added to the module you can use the info command to show an overview:

(Mage2Gen) info

Mage2gen/Test

Consoles

Index  Action name  Short description
--------------------------------------------------------------------------------
0      test         Test log command
--------------------------------------------------------------------------------

Remove snippet

When you want to remove an added snippet you can use the remove <snippet name> <index> command, to remove the snippet from the module:

(Mage2Gen) remove console 0
Removed Console snippet

Generate module

When you are ready with your module and added the snippets you want to use, you can generate the module with the generate command. If you are inside a Magento 2 project directory, it will select the default path for the module:

(Mage2Gen) generate
Generate path [/media/data/Downloads/magento2/app/code]*:
Path does not exist, do you want to create it? [y/N]: y
Module (Mage2gen/Test) generated to: /media/data/Downloads/magento2/app/code

Example usage library

from mage2gen import Module

# Create a module (Module1) for the package (Mage2gen)
module = Module('Mage2gen', 'Module1')

# Generate module files to folder (to_folder)
module.generate_module('to_folder')

Snippets

Mage2Gen has core classes for creating and merging PHP classes, XML files and static files. For generating a module you don't want to define your PHP class or XML file for basic module concepts like observers, plugins or controllers. This is where snippets come in, which add these concepts based on simple input. The currently supported snippets are listed below. If you would like to add a snippet to Mage2Gen, simply fork this project. Add your snippet or other improvements and create a pull request afterwards.

Controller

Creates a controller with block, layout.xml and template. Can create a controller for frontend and adminhtml.

Params:

• (str) frontname: frontame route for module
• (str) section: subfolder in module/Controller
• (str) action: action class
• (bool) adminhtml [False]: if controller is used for adminhtml

Example:

from mage2gen.snippets import ControllerSnippet

controller_snippet = ControllerSnippet(module)
controller_snippet.add(frontname='mage2gen', section='order', action='json')

Plugin

Creates a plugin for a public method, link to Magento 2 docs

Params:

• (str) classname: full class namespace of class with method
• (str) methodname: method name of class
• (str) plugintype: type for plugin (before, after or around)
• (bool) sortorder [10]: the order the plugin is executed in respect to other plugins.
• (bool) disabled [False]: disable a plugin

Example:

from mage2gen.snippets import PluginSnippet

plugin_snippet = PluginSnippet(module)
plugin_snippet.add('Magento\Catalog\Model\Product', 'getName')

Observer

Create an observer for an event

Params:

• (str) event: event name
• (int) scope [ObserverSnippet.SCOPE_ALL]: handle observer for all (SCOPE_ALL), frontend (SCOPE_FRONTEND) or backend (SCOPE_ADMINHTML)

Example:

from mage2gen.snippets import ObserverSnippet

observer_snippet = ObserverSnippet(module)
observer_snippet.add('catalog_product_save_after')

Create a Snippet

You can create your own snippets. If you would like to add a snippet to Mage2Gen, simply fork this project. Add you snippet or other improvements and create a pull request afterwards. You can read this blog post for an how to guide on creating a snippet.

Base snippet

from mage2gen import Module, Phpclass, Phpmethod, Xmlnode, StaticFile, Snippet

class CustomSnippet(Snippet):
    def add(self, **params):
        # create and add PHP classes, XML and static files to the module

        # Get module name (<package>_<module>)
        self.module_name

        # Add PHP class to module (You can add the same class with different
        # methods and attributes multiple times, Mage2Gen will merge them to
        # one class with all the methods and attributes).
        self.add_class(PhpClassObject)

        # Add XML to module (Same as with the PHP class, you can add multiple
        # XML nodes for the same file !important root node must be the same.
        # An XML node will be merged when the node name and the XML attributes
        # name or id  are the same. When creating a node you can define which
        # attributes make the node unique, default is name and id).
        self.add_xml('full/path/to/xml/with/file/name', XmlNodeObject)

        # Add static file
        self.add_static_file('path/to/file/location', StaticFileObject)
