The Rhino Package Manager (a.k.a. Yak)

What is the Rhino Package Manager?

The Rhino Package Manager is a package manager for the Rhino ecosystem, also refered to as Yak. The Package Manager assists in the discovery, installation, and management of Rhino and Grasshopper resources within Rhino. Examples include plug-ins, components, scripts, and material definitions. If you want to learn more about the Package Manager, make sure to visit the Package Manager documentation.

Can I upload my food4Rhino plugins to the Package Manager? 

Yes! food4Rhino makes it easy to upload plugins to the Package Manager through a user friendly user interface. 

As of now, it is possible to upload .rhp, .gha, .ghpy plug-in files to the Package Manager. You can also upload ZIP files. In order to upload your plugin from the food4Rhino site, the plug-in and its content must adhere to a package specification, which you can see in the Package Manger website

The user interface provided by food4Rhino makes it easy to upload your plugins to the Package Manager and fill in the requirements so that your food4Rhino plugin can become a package easily:

  1. In order to upload your plug-in to the Package Manager, you must first login to food4Rhino using a Rhino Account. If you don't know how to log-in using a Rhino Account, please see Rhino Accounts
  2. Head to your My Content tab by clicking on your user name. For each plug-in that you have already uploaded to food4Rhino, you will see a new option to Push in a column named YAK, if the first file is a rhp, .gha, .ghpy or ZIP file.

  3. After clicking on Push, you will be presented with a user interface to upload your plug-in to the Package Manager:

  • Please note that food4Rhino automatically selects the last file uploaded to your plug-in in order to be submitted to the Package Manager.
  • Package Name refers to the unique name that the plug-in will receive in the Package Manager. See the Package Manager reference about naming.
  • Version refers to the version that the package will have in the Package Manager. See the Package Manager reference about versioning.
  • Authors refers to the authors of the plug-in in the Package Manager. (Not to be confused with the owner of the package, which is associated with the Rhino Account who uploads it). See the the Package Manager reference about authors.

Can I synchronise a package published via the Package Manager with food4rhino?

Yes! You can create a new App in food4Rhino with a link to your the Package Manager package.

  1. Login to food4Rhino using a Rhino Account. If you don't know how to log-in using a Rhino Account, please see Rhino Accounts
  2. Head to your 'My Content' by clicking in your user name.
  3. Click on Create App from Yak
  4. Enter the Package Name and click on Submit
  5. Edit the newly created App page to complete the description and other details.

Here you can find the instructions on how to push a package to the server.

Can I delete my food4Rhino plug-in from the Package Manager? 

Once a package has been uploaded to the Package Manager, it's currently not possible to delete it. However, it is possible to remove it from the index with the Yank command. See the the Package Manager reference for the Yank command.

In order to Yank a plug-in from the the Package Manager index from the food4Rhino site, there is an option in the plug-in row under the YAK column:

Once a package has been yanked from the Package Manager, the next immediate version is available. For instance, if you have just yanked version 5.0.0 of a package, then version 4.0.0 will be the next one available in the the Package Manager server. In order to yank all versions, you must do so one by one until the Yank button is no longer available.

Which license should I choose?

If not specified otherwise, the software apps and resources hosted in food4Rhino enjoy copyright protection as any creative work:

food4Rhino is based in the Europe Union, so the EU directive 2009/24/EC applies:

The author of each app may choose a different and maybe less restrictive software license scheme, that you can view by clicking the “License” link in the app page. Some of these license types are:

Even if the source code is given with the app, the code is copyrighted by default. People can read the code, but they have no legal right to use it. To use the code, you must contact the author directly and ask permission.

Does my app or resource have the right license?

Here are three reasons why you might want to update your license:

  • No License - When you created your app or resource you did not specify a license or the link to the license page you provided does not contain an appropriate license. Additionally, some licenses, such as MIT, require you to distribute a copy of the license with your plugin.
  • GPL License - Since Rhino is proprietary software, the GPL is not compatible for Rhino plugins, script, or GH definitions. If you wish to apply a copyleft license to your code, you can choose the LGPL which covers the use case of executing code within an application that does not have a GPL license.
  • Creative Commons License - While licenses such as Creative Commons are great for resources such as textures, documentation, and tutorials, they are not recommended for plugins, scripts, and Grasshopper definitions. See this article for why it isn’t recommended to apply a CC license to software. Note: The CC0 license (public domain) is appropriate for all types of content.

Important: Please ensure your plugin, script, or gh definition does not depend on any libraries with a license that is not compatible with Rhino.

If you wish to update your content licensing, simply log into Food4Rhino, go to My Content, edit the app or resource, and select the license which best fits how you want others to use what you’ve made.

When will my content be published?

  • Once your Content is all defined, click on the Publish button on the creation page.
  • We will then review the content and make it public. This is done by a human from Europe, it usually takes 1 or 2 days.   

Suggestions for a successful project


When you choose the icon and the text for your project and release, keep in mind that a nice looking icon and comprehensive explanation will greatly improve the final user experience.

We encourage every developer to have a custom drawn icon, and not a screenshot, to explain their project and make it memorable. The color choice is yours, and you can use tones that will remind users of your corporate look or something specific for your project. Do not use a blank icon.

Also, write a short introductory phrase at the beginning of the overview. Start with the name of your plug-in, then use a verb, then expand on the usage of your plug-in and explain what it means. You could write something like this: “The Ufo plug-in detects and monitors paranormal activity that is happening immediately around you while you are using Rhino's 3D modeling abilities”.
Images and Videos are very important for users to quickly grab what your plugin does, feel free to add as many as you want!

How can I contact with the users who downloaded my content?
