Plugin API

Macro Deck and it's plugins are written in C# using the .NET Core framework.

Before you start

  1. Go to "%Appdata%\Macro Deck\plugins" and create a folder with the standard name space you are planning to use as name. Use following naming scheme: "YourName.YourPluginName"

Creating the project

  1. Start by creating a new class library. Important: you need to use .NET Core 3.1 for this, not .NET Framework!
  2. Import "Macro Deck 2.dll", which can be found in the installation directory, as a reference to the project.
  3. Go into the properties of your project and set the name and the version of the plugin in the package category.
  4. Change the standard name space. Use following naming scheme: "YourName.YourPluginName"
  5. Make sure you add <UseWindowsForms>true</UseWindowsForms> to <PropertyGroup> in your project's configuration.
  6. Now you can start with the main class

Import the required references

using SuchByte.MacroDeck.Plugins;
using System.Collections.Generic;
using System.Drawing;
using System.Reflection;

Creating the main class

public class Main : MacroDeckPlugin
  // Optional; If your plugin can be configured, set to "true". It'll make the "Configure" button appear in the package manager.
  public override bool CanConfigure => true; 

  // Gets called when the plugin is loaded
  public override void Enable()
    this.Actions = new List<PluginAction>{
      // add the instances of your actions here
      new ExampleAction(),
  // Optional; Gets called when the user clicks on the "Configure" button in the package manager; If CanConfigure is not set to true, you don't need to add this
  public override void OpenConfigurator()
    // Open your configuration form here
    using (var configurator = new Configurator()) {

Creating a action class

public class ExampleAction : PluginAction
  // The name of the action
  public override string Name => "Example action"; 
  // A short description what the action can do
  public override string Description => "Action description"; 
  // Optional; Add if this action can be configured. This will make the ActionConfigurator calling GetActionConfigurator();
  public override bool CanConfigure => true; 
  // Optional; Add if you added CanConfigure; Gets called when the action can be configured and the action got selected in the ActionSelector. You need to return a user control with the "ActionConfigControl" class as base class
  public override ActionConfigControl GetActionConfigControl(ActionConfigurator actionConfigurator)
    return new ExampleActionConfigurator(this, actionConfigurator);
  // Gets called when the action is triggered by a button press or an event
  public override void Trigger(string clientId, ActionButton actionButton)

  // Optional; Gets called when the action button gets deleted
  public override void OnActionButtonDelete()

  // Optional; Gets called when the action button is loaded
  public override void OnActionButtonLoaded()

Creating the ActionConfigurator class

If your action needs to be configured, your plugin needs a ActionConfigControl. Start with adding a user control to your project. Then you need to add the "ActionConfigControl" class as a base class.

public partial class ExampleActionConfigurator : ActionConfigControl
  // Add a variable for the instance of your action to get access to the Configuration etc.
  private PluginAction _macroDeckAction; 

  public ExampleActionConfigurator(PluginAction macroDeckAction, ActionConfigurator actionConfigurator)
    this._macroDeckAction = macroDeckAction;

Saving the config of an action

If your action can be configured, you need to store the configuration as a string (can be json formatted) in the Configuration variable of your PluginAction. Macro Deck provides a boolean in the ActionConfigControl class which you can override. This gets called when the user closes the action configurator. You can force the user to configure the action by returning false if e.g a text box is not filled out.

public ExampleActionConfigurator(PluginAction macroDeckAction, ActionConfigurator actionConfigurator)
  this._macroDeckAction = macroDeckAction;

public override bool OnActionSave()
  if (String.IsNullOrWhiteSpace(this.exampleTextBox.Text)) {
    return false; // Return false if the user has not filled out the text box
    JObject configuration = new JObject();
    configuration["example"] = this.exampleTextBox.Text;
    this._macroDeckAction.ConfigurationSummary = configuration["example"].toString(); // Set a summary of the configuration that gets displayed in the ButtonConfigurator item
    this._macroDeckAction.Configuration = configuration.ToString();
  } catch { }
  return true; // Return true if the action was configured successfully; This closes the ActionConfigurator

Saving plugin settings

If you want to save some plugin wide settings, Macro Deck provides two simple functions for this

Set a string value with

SuchByte.MacroDeck.Plugins.PluginConfiguration.SetValue(IMacroDeckPlugin plugin, string key, string value);

or get a string with

var configuration = SuchByte.MacroDeck.Plugins.PluginConfiguration.GetValue(IMacroDeckPlugin plugin, string key);

Saving login credentials

Never save login credentials like passwords, tokens, etc. unencrypted! Macro Deck provides simple functions to store credentials encrypted.

Set credentials with

Dictionary<string, string> keyValuePairs = new Dictionary<string, string>();
keyValuePairs["email"] = "";
keyValuePairs["password"] = "password1234";
SuchByte.MacroDeck.Plugins.PluginCredentials.SetCredentials(IMacroDeckPlugin plugin, Dictionary<string, string> keyValuePairs);

and get a list of all the credentials of the plugin which are already unencryped

List<Dictionary<string, string>> credentialsList = SuchByte.MacroDeck.Plugins.PluginCredentials.PluginCredentials.GetPluginCredentials(IMacroDeckPlugin plugin);

Setting variables

Maybe your plugin gets data you want to store in a variable like temperatures, states, etc. If the variable don't exists, Macro Deck automatically creates it. You just need to set the value.

Please note: please only use lower case variable names without white spaces and any special characters

Example: my_awesome_variable

SuchByte.MacroDeck.Variables.VariableManager.SetValue(string name, object value, VariableType type, IMacroDeckPlugin plugin, bool save = true); // if your variable changes often, set save to false

Using the built in logger

You can log things with the built in MacroDeckLogger

MacroDeckLogger.Trace(MacroDeckPlugin plugin, string message); // Log a trace (loglevel 1)
MacroDeckLogger.Info(MacroDeckPlugin plugin, string message); // Log something that can be useful (loglevel 2)
MacroDeckLogger.Warning(MacroDeckPlugin plugin, string message); // Log warnings (loglevel 3)
MacroDeckLogger.Error(MacroDeckPlugin plugin, string message); // Log errors (loglevel 4)

Compiling and adding the manifest

  1. Create a folder in %Appdata%\Macro Deck\plugins called like the standard namespace of your plugin.
  2. Compile your plugin and copy the output .dll file into %Appdata%\Macro Deck\plugins\STANDARD_NAMESPACE\
  3. After that you have to create a plugin manifest. Create a .xml file, called Plugin.xml and place it in the same directory.
<?xml version="1.0"?>
<PluginManifest xmlns:xsi="" xmlns:xsd="">

Requirements for the plugin icon

  • The icon must be in the PNG format
  • The icon size must be 64x64px
  • The filename of the icon must be Plugin.png
  • To test it locally, copy the icon file into %Appdata%\Macro Deck\plugins\STANDARD_NAMESPACE\
