Support additional URI schemes for hyperlinks in notes

[prntss]

Due to limitations with Gramps notes, I supplement notetaking with other tools and would like to link directly to them. When adding a note with the Type = "Link", hyperlinks are only rendered if the text begins with http:// or https://. Links added through the editor behave the same way. Any custom URI schemes (e.g., obsidian://) remain plain text and can’t be used for deep linking.

Gramps Desktop renders hyperlinks of other URI schemes without issue when using Link Type="Internet Address", so bringing similar support to Gramps Web would improve consistency and usability.

I’m requesting expanded link detection for notes so additional URI schemes can be recognized. Possible approaches include accepting any RFC 3986–valid scheme before ://, or using a safe allow-list such as ['http', 'https', 'obsidian', 'notion', 'bear', ...].

Good point. I investigated the issue - it's not about link detection in the frontend (which we use for making plain-text URLs clickable), it's about sanitization of URLs in the backend. Currently, bleach strips all URLs that are not http, https, or mailto.

So, I think this is easy to implement but I am getting some second thoughts. I am a huge fan & user of Obsidian, but does it actually make sense to allow deep linking into a desktop application that only a single user of the web app has access to? This link will break for all other users, which will look like a bug - or even worse, it might open the desktop app on their system and a note with the same name but different content.

What do you think?

Thanks for looking into this. I use Gramps Web in a personal/single-user setup, so I hadn’t really considered the multi-user concerns. I had a few ideas, like letting admins configure an allow-list for URI schemes or automatically treating non-HTTP/HTTPS links as private notes—but they all feel like overkill for the value they add.

I’ve also been exploring a small Obsidian plugin that would let me link a note directly to a Gramps Web record, which might cover most of my workflow without needing changes on the Gramps side.
