Summary of the issue you are facing:
Markdown files keep being mangled by the Nextcloud frontend, even when not opened for edit.
The Nextcloud frontend should not overwrite files unless they are physically edited by the user. This is especially the case when open_read_only_enabled is used.
An open_force_read_only or similar setting would be appreciated, to allow viewing rendered Markdown files on the frontend but not editing them, which is very easy to do accidentally.
Steps to replicate it (hint: details matter!):
- Setup a Nextcloud instance
- Set
occ config:app:set text open_read_only_enabled --value=1– this will ensure the Markdown files are opened in “view” mode, not with the editor - Setup Nextcloud desktop client sync
- Create a Markdown file on the desktop, write some content into it (tables are best to see the mangling)
- Let the file sync to the cloud
- Open the Nextcloud web frontend
- Navigate to the directory where the Markdown file sits
- Open the Markdown file (it will open in view mode)
- Wait for a few seconds
- Note how the file on your desktop has changed (look at the timestamp,
diffwith a copy, or keep it open onkwriteorkate). The web frontend may or may not show a message to the effect that there is a “file conflict”, even though you never touched a comma in the file itself – the frontend appears to rewrite Markdown files on its own initiative the moment they are opened, even for viewing.
