Duplicating Foundation or Horizon

Product Support

AI-generated summary

The discussion revolves around duplicating the Foundation or Horizon themes in Discourse for debugging purposes. RGJ explains that while they typically duplicate themes by creating a copy via the admin interface, this method doesn’t work for Foundation or Horizon, as these themes are part of the core and lack options for export or git repository import. Moin clarifies that Foundation is essentially an empty theme, and suggests that Horizon can be duplicated by using its files directly from the GitHub repository. RGJ acknowledges the limitations of the current system, hinting at challenges posed by the large monorepo structure.

So I got distracted a bit, hitting a bug while searching for a solution, but in the end I didn’t find a solution either.

Sometimes, when debugging odd behaviour, I create a copy of the theme (either “create new” and have an empty default theme, or “from a git repository” and adding the link to the repo, or “export” and then download it and choose “from your device” and re-upload), make it user selectable, select it myself, and start removing theme components to single out the one that is misbehaving. By creating a copy of the theme I can do this on a production site without disrupting life for other users.

So today I wanted to find out why something was acting up, and I went to Admin - Appearance - Themes, and wanted to have another instance of “Foundation” for my debugging exercise.

Either that’s not possible, or I don’t understand how to do it.

  • create new gives me an empty one
  • since Foundation and Horizon are in core, there is no repository link
  • there are no ‘Export’ buttons for these guys

Isn’t foundation the same as a new, empty theme?

I don’t see anything here apart from the description and the screenshots:

You are correct, as always. Still, same issue for Horizon.

I think you can use the files in discourse/themes/horizon at main · discourse/discourse · GitHub to create a copy of horizon

I guess there are some disadvantages to having a large monorepo…
