This probably would also improve compatibility with apps like iA Writer on iOS. Actually, NC Text and iA Writer treat lists with indentations differently:

• NC Text uses 2 space characters for list intendation
• iA can be configured to use spaces, but expects 4 spaces per intendation level

Paragraph indentation is nothing that can be represented in markdown as trailing whitespace would just be removed. For code blocks we should fix this. 👍

This is a different topic, please open a separate issue to discuss something like this. In general I would like to have some more information on how other markdown editors handle this, as two spaces are definitely fine according to the commonmark standard.

This is a problem with bullet points, too. You have to backspace to make the bullets on one line, press enter again, then hit tab.

Please share some more detailed steps about that as I cannot see any issue with the tab indentation on lists:

@juliushaertl Ahh, good catch. I figured out the use case that was causing it. It was happening for me in every file because all of my files I was trying to change were formatted the same way.

Upload a file into Nextcloud of test.md:

This is a test with a blank line after it.

* Bullet 1
* Bullet 2

• Now open the file in Nextcloud Text, and place your cursor at the T in "This".
• Hit the ordered list button. You now have 3 bullets, however there is a "hidden" carriage return from the blank line that existed before
• Place your cursor next to the B in "Bullet 1"
• Press tab
• Focus goes up the browser's menu bar

To fix it, you have to backspace from "Bullet 1" up to the previous line and press enter. This makes since because there is actually an empty line there, but Text (or the editor, rather) isn't giving any indication the blank line is there.

edit
Maybe this is a Prosemirror thing?

Might be, could you check at https://tiptap.scrumpy.io/ if you can reproduce it there?

Sure thing, and yes, to an extent. Since I can't start from raw MD I faked it by inserting a blank line and backspacing. You can see in the GIF. Process was:

• Type "test"
• Press enter twice
• Type "test"
• Ordered list button
• Go to blank line between "test"s
• Backspace
• Ordered list button (now that invisible return from the line is still there but you can't see it)
• Click on second line
• Tab (jumps out of editor instead of indenting)

is this something that needs to be implemented from scratch or is indenting supported by the underlying library and it's just a matter of calling the right function ? @juliushaertl

I just tested this on latest Text in Nextcloud 24 and the bug has been fixed by the list item improvements by @max-nextcloud 🎉

[Isac99]

Looks like this bug is back in version 27.0.1 - just upgraded and the tab key no longer indents bullet points are unordered lists.

@Isac99 I cannot reproduce this myself. But someone else reported this as well in #4389. Could you reply to my questions over there?
