Force Rhino plugin loading at startup

software_comas · December 22, 2020, 7:26am

Hi guys!
I’ve noticed that Rhino uses a kind of “lazy loading” approach when it comes to plug-ins loading: it seems that a plug-in is not loaded until one of its commands is executed or until one of its panels is shown.
I wonder if there’s a way to tell Rhino to load a plug-in as soon as possible, when it starts.
Thanks

Override LoadTime on your plug-in and return PlugInLoadTime.AtStartup.

Here is how Raytraced loads itself at startup (unless load-protected):

github.com

mcneel/RhinoCycles/blob/c445d5fb198a609f91ebbb3003995c98a6998d5c/Plugin.cs#L42


using System.Management;
namespace RhinoCycles
{
	public class Plugin : PlugIn
	{
		/// <summary>
		/// Make sure we load AtStartup so that our view mode is
		/// available even when RhinoCycles isn't the current renderer
		/// </summary>
		public override PlugInLoadTime LoadTime => PlugInLoadTime.AtStartup;
		private bool pluginLoaded = false;
		private bool IsIntelOpenClSdkInstalled() {
			List<string> proglocs = new List<string>
			{
				Environment.GetEnvironmentVariable("PROGRAMFILES(x86)"),
				Environment.GetEnvironmentVariable("PROGRAMFILES")
			};

Thanks a lot, @nathanletwory!
