Can't reference other notes through relative links

[blacklight]

Steps to reproduce

• Create a Markdown file named index.md with e.g. the following content

# Index

- [Topic A](./A.md)

• Create a file named A.md in the same directory

• Try and click on the link in index.md

Expected behaviour

The note object linked to A.md should be opened

Actual behaviour

The URL is resolved with respect to the current note ID prefix, so the redirect goes to /apps/notes/note/A.md, which doesn't exist.

This is particularly relevant when using something like e.g. vimwiki (or anything that allows you to manage Wiki-like notes in Markdown format). Relative URLs in these context are usually resolved to file names, but Nextcloud Notes works with internal note IDs instead.

Would it be possible to add an intermediate resolver that checks if the requested URL points to a file indexed as a note, and in that case redirect the user to the right URL?

We can reference other notes. Just have to use the note id (see number at end of note link) not the note name:

@enjeck I know that I can reference notes by ID, but it doesn't answer my use case (I'm just realizing that this should have been a feature request rather than a bug btw).

If I want to access the notes from another client pointing to the same directory (e.g. Obsidian, VimWiki...) then most likely that client knows nothing about Nextcloud note IDs - but it probably knows about filenames.

A good solution that may make things work with all clients may look like:

• If a note URL is a relative URL in the format [0-9]+ then it's most likely a note ID
• If instead it's in the format some/path/Note(.md)?, and that path exists, then render the associated note ID

[enjeck]

• If instead it's in the format some/path/Note(.md)?, and that path exists, then render the associated note ID

Could be possible, given that the API gives us an internalPath with that format:

Request:
curl -u admin:admin \
  "http://nextcloud.local/apps/notes/api/v1/notes"
