Theming app

[jancborchardt]

@schiessle let’s get a work-in-progress pull request going here. ;)

I found 2 good color pickers:

• https://casesandberg.github.io/react-color/ seems to be the best one – Chrome style picker with alpha option removed)
• https://bebraw.github.io/colorjoe/ RGB picker with extras seems good

Also todo:

• add labels to fields
• make sure color and logos are replaced everywhere possible (favicon etc)

Will we also integrate generating branded clients like it was possible with ownBrander?

PR against master → milestone 10. backport will be 9.

Branding clients is a bit harder, because you need a huge toolchain to build it. So this is limited to the web UI for now.

@schiessle when rebasing this against master, I get an internal server error. Can you check this out and the color picker as well?

cc @MorrisJobke @LukasReschke for JS help maybe ;)

working at it at the moment. Seems to have more influences at the core as expected and also breaks initial installation at the moment. Let's see what i can do.

@jancborchardt please have a look. The basic functionality is now there but we can probably improve the visual presentation.

I don't really understand why I can't update the logo directly after it was uploaded: https://github.com/nextcloud/server/pull/59/files#diff-7336f3dab52c02ef94f856620590f56bR34 @blizzz do you have a idea why this doesn't work?

[blizzz]

👎 remote code execution. You can upload a PHP file as icon (e.g. phpinfo.php) and open it via http://nextcloud.server/themes/theming-app/core/img/phpinfo.php

For one, you need to wrap the path into url("…"), for the other the path was wrong. I got it working with:

logos[i].style.background = "url('" + OC.getRootPath() + "/themes/theming-app/core/img/" + value + "')";

[schiessle]

Thanks @blizzz, this works!

@LukasReschke What's the best way to prevent people from uploading PHP files als background image? Maybe we can also just block all img/ paths from execution?

[blizzz]

isn't themes read-only by default?

[schiessle]

yes, I check it here https://github.com/nextcloud/server/pull/59/files#diff-d1ebf4e994bc54194a285284dda2224aR40

But good point to also add a check here to only enable the theme if we can write to the themes folder.

[LukasReschke]

As discussed with @schiessle I'll hijack this branch with some security hardenings for this feature.

[joergmschulz]

Do you already have some kind of specification document for theming? This is the area where I could help - if somebody gives me a hint for a starting point.

[schiessle]

@joergmschulz great! 😄 Did you already saw our documentation repository? Would be great to have for the administration documentation a short description of the theming app, with a screenshot and so on: https://github.com/nextcloud/documentation/tree/master/admin_manual

Would be great if you could help with this!

[jancborchardt]

@joergmschulz although the theming app ideally should be as self-explanatory as possible. :) Feedback on how it works is always good! For now we stick to the core 5 things:

• name
• website
• slogan
• color
• logo

[LukasReschke]

#59 (comment) all done

[jancborchardt]

Should I also create new issues for the other 2 points in #59 (comment) or are they planned to be fixed as part of this? cc @LukasReschke @schiessle

[MariusBluem]

at least the second point with the non-working button should be fixed here 😁

[MorrisJobke]

Tested and works 👍

[LukasReschke]

@jancborchardt check fe1089e and 4b79420. Testing appreciated.

[jancborchardt]

Great stuff! 👍 works and looks nicely now

[jancborchardt]

Yeeha, awesome work! :)
