Adding fonts to NextCloud + Collabora

[m-si]

I played around and maybe this is a solution to @nebulon at least for the "merge"-situation with new upstream font releases...so what about:

RUN if [ -d /app/data/fonts/ ]; then \
      rsync -a --update --existing /opt/collaboraoffice/share/fonts/ /app/data/fonts/  \
      && rm -r /opt/collaboraoffice/share/fonts/ \
    else \
      mv /opt/collaboraoffice/share/fonts/ /app/data/fonts/ \
    fi \
    && ln -s /app/data/fonts /opt/collaboraoffice/share/fonts/

With that it checks initaly wether /app/data/fonts/ exists (if not simply moves and symlinks back) and if folder already exits updates only the files that are newer and persists the deletion of font files in /app/data/fonts/ and keep changes of files from upstream (until they are deleted)...

[nebulon]

@m-si wouldn't that also copy back your delete fonts on an app restart?

[m-si]

@nebulon no this is prevented by the --existing flag...that's the reason why I initially suggest to move the whole thing and afterwords only update the (still) existing... to get a whole copy of the primary folder one has to delete the font folder in app/data... then there will be again the full copy/move...

[m-si]

@nebulon Another try hopefully less hackish... According to the solution of rLoutrel found here ... maybe it is sufficient to simply:

RUN ln -s /app/data/fonts /opt/collaboraoffice/share/fonts/truetype/local

This one won't add /usr/share/fonts/ as extra volume to collabora and we won' have the ability to get rid of the intially installed fonts but should make it at least possible to add custom fonts via /app/data/fonts. So this might be a solution to the initial Question of SirFiChi...

Any chance of another look at this please @nebulon — these little things really help with user happiness, and the latest version is well worth the effort for making out go-to online office suite with Nextcloud.

[m-si]

@nebulon I see there is always a lot to do, so maybe it's an idea to mention it again. Do you think we might have a chance to add fonts like that…?

RUN ln -s /app/data/fonts /opt/collaboraoffice/share/fonts/truetype/local

[nebulon]

Thanks for bringing this up again. I have published a new app package which supports adding fonts now. After copying the TTF fonts into the folder, the app has to be restarted as mentioned in https://docs.cloudron.io/apps/collabora/#adding-fonts

@nebulon
For some reason all the fonts I added like that show in in Collabora in Nextcloud but are invisible.

Ever encountered something like that?

[nebulon]

@BrutalBirdie what does invisible mean? Where are they invisible? Does fc-match <fontname> correctly recognize the font in the webterminal?

Looks wrong to me...

fc-match --all

Does also not include the fonts.
Also having the .ttf files plain in no sub folder in /app/data/fonts yields the same results.

The fonts works tho on the local system.

[nebulon]

I tried this just now and I can confirm that the rendering in the actual document is not working. Seems like some upstream bug then, which needs investigation. Unfortunately there are no errors anywhere.

[m-si]

@BrutalBirdie While playing around to overcome this error. I found an alternative solution. It doesn't fix the collabora CODE font issue mentioned here, but makes it possible to add fonts to a Nextcloud instance hosted via cloudron.

It works with Nextclouds' ability to add fonts as remote_fonts therefore do the following:

1. Add the desired fonts at https://[YOUR.NEXTCLOUD.DOMAIN]/settings/admin/richdocuments
2. Switch to the apps-filemanager of your cloudrons Nextcloud. Create the folder ~/apps/richdocuments/settings
3. Find out in which [APP-DATA-DIRECTORY] Nextcloud saves the richdocuments-data inside the directory ~/data (e.g. appdata_ocv42l2jdx7f)
4. in the newly created folder, create a file fonts.json (so ~/apps/richdocuments/settings/fonts.json exists) with the content

{
    "kind": "fontconfiguration",
    "server": "[YOUR.NEXTCLOUD.DOMAIN]",
    "fonts": [
        {
            "uri": "https://[YOUR.NEXTCLOUD.DOMAIN]/[APP-DATA-DIRECTORY]/richdocuments/fonts/[FONTNAME-1].ttf"
        },
        {
            "uri": "https://[YOUR.NEXTCLOUD.DOMAIN]/[APP-DATA-DIRECTORY]/richdocuments/fonts/[FONTNAME-2].ttf"
        }
    ]
}

5. restart the collabora app
6. restart the Nextcloud app

Additional, remove any font added to the collabora fonts directory...

Edit: After trial and erroring even more, I found nextcloud updating the fontlist only if ~/apps/richdocuments/settings/fonts.json is again saved.

Edit-2: Unfortunatly after a collabora update nextcloud needs to be restarted again to make the font changes again available…

@nebulon maybe this might solve the issue?
cheers
