Impress: Make master slides import from templates folder available for use in the sidebar

[Rash419]

Is your feature request related to a problem? Please describe. Import templates from nextcloud in "master slides" of Collabora Online's impress, similar to remote fonts

Describe the solution you'd like

• We are adding a new remote_asset_config.url config in COOL with PR https://github.com/CollaboraOnline/online/pull/10463. This will work similarly to remote_font_config

• This will be upgrade a from remote_font_config.url which was only designed for fonts but remote_asset_config can take fonts, templates and can also be extended in the future if we want fetch other kind of assets.

• from the richdocuments' side I expect a new endpoint which can serve json which can have both fonts and impress presentation templates.

• json format would be

  {
  "kind": "assetconfiguration",
  "server": "remoteserver",
  "templates": {
  "presnt": [
    {
      "uri": "http://localhost:8080/static/impress-template/template1.otp",
      "stamp": "1"
    },
    {
      "uri": "http://localhost:8080/static/impress-template/template2.otp",
      "stamp": "2"
    },
    {
      "uri": "http://localhost:8080/static/impress-template/template3.otp",
      "stamp": "3"
    }
  ]
  },
  "fonts": [
  {
    "uri": "http://localhost:8080/static/font/font1.ttf",
    "stamp": "1"
  },
  {
    "uri": "http://localhost:8080/static/font/font2.ttf",
    "stamp": "2"
  },
  {
    "uri": "http://localhost:8080/static/font/font3.ttf",
    "stamp": "3"
  }
  ]
  }

  Additional context

• For backward compatibility we have kept remote_font_config.

• I have created RemoteConfigServer for testing

Very nice proposal. Some quick feedback/questions:

• stamp is quite unintuitive naming imo, maybe call it version or etag or mtime which are more common names from my perspective
• It would just be regular odp files where the master slides are used then? Would otp files also be supported? How about pptx?

[juliusknorr]

• Implementing the endpoint should be straight forward based on the font list endpoint https://github.com/nextcloud/richdocuments/blob/9ca8814005a3bea3ca949d12a554034c7e3ee96b/lib/Service/FontService.php#L97-L113
• As collabora only has one global list of templates and not individual ones per user joining a document, we can only use admin provided templates here
  • As a start we can pull the templates form the richdocuments system template directory
  • We can think about shipping our templates from the example files by default in richdocuments
  • Optional: Otherwise we'd need a improved admin provided template mechanism https://github.com/nextcloud/server/issues/46455

"presnt"

is that a typo or any reason to not have "presentation" or something like that?

@juliusknorr Not a typo but we can use "presentation" or "impress" I guess

Thanks

* stamp is quite unintuitive naming imo, maybe call it version or etag or mtime which are more common names from my perspective

sure. I can update it to use "version" .

* It would just be regular odp files where the master slides are used then? Would otp files also be supported? How about pptx?

I have tested only with "otp" files as of now because they are the template files for impress. I will check and get back to you : )
