Nextcloud editor mangling reference links

[cosmiczoo]

Short summary of the issue

Nextcloud markdown editor quietly changes links in markdown file containing links in the format [[Name of a page]] to [[Name of a page[[

• Markdown syntax is not properly rendered in text
• Markdown syntax is removed after closing text
• Markdown syntax is changed after closing text
• Something else: Please describe more in detail

Example markdown file

Open a markdown file created in Nextcloud say New text file.md
Contents of file:

This is some text and here is a [[Link to another page]] in Logseq's markdown dialect.

Open in Nextcloud Markdown editor.
The [[ ... ]] references look unchanged in Nextdown editor.
Make no changes to the file.
Close the file.

Resulting markdown file New text file.md after opening in text

This is some text and here is a \[\[Link to another page\]\] in Logseq's markdown dialect.

Preferred solution alternatives

1. If the syntax is not in the Nextcloud Markdown dialect, make the editor pass through the unsupported text unmodified
2. If the file is not edited but only read, do not change the file or reinstate the file.
3. Plug in a suitable alternative markdown editor that is tolerant of foreign markdown.

Thanks a lot for reporting this and providing all relevant information. @max-nextcloud Do you see any quick way to solve that? Maybe that is an interesting ticket to pair with @JuliaKirschenheuter on text markdown handling and internals.

The syntax is quite common I think so worth to spent some time looking into that I'd say.

Obsidian uses the [[Link]] syntax as well, so editing Obsidian files on Nextcloud also renders any links unusable. I would be really glad to see this resolved, because the Text app looks fantastic otherwise!
