Quick Start

In this section, it is shown how to create a plugin from scratch with the template command provided by ALFAsim-SDK. With this template, you can easily customize your application to extend ALFAsim functionality.

This allows you to experience the complete creation of a plugin workflow in a short time.

Set up the environment

The ALFAsim-SDK is a Python package that helps developers in the process to create a Plugin for ALFAsim, to use this tool it is necessary to have a Python Interpreter with at least version 3.6. For more details on how to install Python check the official docs.

Note

It is recommended that you install the ALFAsim-SDK using a Python Virtual Environment. For more details, see Virtual Environments and Packages in Python documentation.

From a terminal, and inside a virtual environment, update pip:

>>> python -m pip install -U pip

Install the ALFAsim-SDK with:

>>> pip install alfasim-sdk

Also, make sure to have at least the following version for this software:

• CMake at least version 3.5.2

• Ninja at least version 1.7.0

The alfasim-sdk package has several commands that can be visualized by running the help option.

>>> alfasim-sdk --help

Creating a Plugin Project

To create a new project, run:

>>> alfasim-sdk template

After the execution of the command above, you will be prompted to fill the following options (all required):

>>> alfasim-sdk template
... -- Plugin Caption: Myplugin
... -- Plugin Id: myplugin
... -- Author Name: ESSS
... -- Author Email: <email>@<server>

Plugin Caption

The caption to be used across the application to identify the plugin.

Plugin Id

The name of the plugin to be referenced during the development.

Author Name

Name of the plugin author to be displayed.

Author Email

Email of the plugin author to be displayed.

To check all options, call the help command:

>>> alfasim-sdk template --help

After the execution of the template command the generated plugin project will have the following structure:

\---myplugin
    |   CMakeLists.txt
    |   compile.py
    |
    +---assets
    |       plugin.yaml
    |       README.md
    |
    \---src
        |   CMakeLists.txt
        |   hook_specs.h
        |   myplugin.cpp
        |
        \---python
                myplugin.py

The highlights here are for:

plugin.yaml

File with all information about the plugin that will be used by ALFAsim.

myplugin.py

Implementation of the hooks for customization of the UI interface, or the solver configuration hooks.

myplugin.c

Implementation of the hooks for customization of solver.

Check out the Plugin Structure section for more details about how the folder and files are structured, and also, check the Plugin by Example that shows how to create simple plugins that make use of the User Interface Hooks and the Solver Hooks.

Creating a package

From the root directory of the plugin, execute the command alfasim-sdk package. This command will compile your C/C++ implementation and include the shared libraries inside a artifacts directory and the generated plugin on the root directory with the extension hmplugin.

>>> cd myplugin
>>> alfasim-sdk package
... -- Package Name: myplugin

The plugin directory will have the following structure when executing from a Windows Operating System:

\---myplugin
    |   CMakeLists.txt
    |   compile.py
    |   myplugin-1.0.0-win64.hmplugin
    |
    +---artifacts
    |       myplugin.dll
    |       myplugin.lib
    |
    +---assets
    |       plugin.yaml
    |       README.md
    |
    +---build
    |       < ... >
    |       < ... >
    |
    +---package
    |       myplugin.dll
    |       plugin.yaml
    |       README.md
    |
    \---src
        |   CMakeLists.txt
        |   hook_specs.h
        |   myplugin.cpp
        |
        \---python
                myplugin.py

Installing the plugin

With myplugin.hmplugin file, it is now possible to install it on ALFAsim application. From the menu bar select the Plugin Manager option, as illustrated in the figure below:

In the Plugin Manager windows, install myplugin.hmplugin file plugin.

By clicking on the plugin name, it is possible to visualize the content from the README.md file.

Restart the application and check the recently installed plugin available over the Tree.
