[SUPPORT] Cannot link to certain heading

[DutchPete]

Question

I have a note with 11 headings, numbered from 1 to 11, though there are subheadings too.
In the outline pane all headings are shown.
However, when I want to link to heading 10 or 11 from another note, the last heading shown in the dropdown list when I press CTRL+Shift+L is heading 9.2.1.
Even when I write out the syntax manually, the link does not work.

Relevant log output in the Log panel

You have to enable the Log panel in the Windows menu!
I did but I don't see it.

Alternatively you can also turn on a log file in the settings.
I did. I it a very big file, so here is what I think may be relevant:

[Dec 21 15:05:43] [debug]: fileUrlInCurrentNoteFolderToRelativePath  - 'path':  "/home/user1/MEGA/Obsidian/Germanys-war-highlights.md"
[Dec 21 15:05:43] [debug]: fileUrlInCurrentNoteFolderToRelativePath  - 'canonicalFilePath':  "/home/user1/MEGA/Obsidian/Germanys-war-highlights.md"

Can you please provide an example note and some markdown where you linked to it? I can't really grasp your issue without more context.

[DutchPete]

Here is the actual file I am talking about.
Germanys-war-highlights.md

Download it, then from any note try to link to heading 10 or 11.

[pbek]

I guess you are talking about the 10th or 11th heading, not a heading 10 or 11, right? Those are all heading 1.
No heading 1 is showing up in the list, because you are not supposed to have multiple of them (according to HTML spec).

[DutchPete]

Yes, I am talking about 10^th and 11^th heading.

you are not supposed to have multiple of them (according to HTML spec)

I don't understand:

1. if you are not supposed to have multiple heading 1, why then does QON show 9 of them?
2. HTML spec: I thought QON follows Markdown specs?

[pbek]

if you are not supposed to have multiple heading 1, why then does QON show 9 of them?

Look closer, none are shown, it shows heading 2 and 3.

Only to make sure we are talking from the same thing: https://www.w3schools.com/html/html_headings.asp

HTML spec: I thought QON follows Markdown specs?

It's not about the Markdown specs, it's about that you are not supposed to have more than one heading 1 in a document.
The h1 should succinctly represent the content on that "page". You can have as many h2, h3 and so on as you like.

[DutchPete]

Gotcha. That means all H1 links in ALL my notes that I have composed in other apps and have many H1 headings have become useless.

BTW, I was using the outline as a guide:

Just do a regular expression replace of ^# with ## and shift all headings or use the script Headline depth buttons.

[DutchPete]

Phew, nothing is lost, as it were.
It will be a useful exercise because I remember someone once mentioning it over at the Obsidian forum, but since Obsidian can handle multiple H1 headings and linking to them, I ignored the comment. I think Logseq also has the same limitation of only 1 H1 per note.

BTW, what is the meaning of the ^ in ^#?

[pbek]

In regular expressions, a ^ signals the start of a line.

I looked at the link dialog code and the code of the linking (that also needs to support that) and it would be possible to support heading 1, but like previously only those headings starting with '#', so still no ======= and ---------- (see https://www.qownnotes.org/getting-started/markdown.html). Those would be hard to parse.

[pbek]

Phew, nothing is lost, as it were.

With plain text files, nothing is lost most of the time... You can search/replace a lot. You could even ask your ChatGPT to manipulate the text for you. 😉

24.12.5

• Both note links and the link dialog are now supporting also heading 1, not only
  heading 2 and up, as long # headings are used (for #3181)

[pbek]

There now is a new release, could you please test it and report if it works for you?

[DutchPete]

I am using the Flatpak version, as that is what there is in my system package manager. I checked on your Flathub page but you have not pushed this version to Flathub yet.

BTW, in your opinion, is the Flatpak version OK to use or would you recommend something else?

[pbek]

The flathub package was just built. Yes, you can use it.

[DutchPete]

Yes, that works fine. Many thanks for amending the app this way.

[pbek]

I think I need to take that feature back, it causes comments in code blocks also to be detected as headings!

[DutchPete]

So, why does an app like Obsidian not have that problem?

[pbek]

Was that a serious question or a troll question?

[DutchPete]

I am not in the habit of trolling, so yes, it is a serious question.

Remember, I am the one who asked for the feature, you are the one who implemented it, now you are the one who is retracting it.

I am surprised you did not realize comments in code blocks would be detected as headings. Code blocks can also be used in Obsidian, yet H1 heading links don't cause that problem, hence my question.

If, however, the question seems stupid to you, don't bother to answer.

[pbek]

It's a different application with a different code base.

[pbek]

25.2.1

• The heading detection in the link dialog and when jumping to the heading in a
  note link was re-implemented and now uses the highlighting states of the note
  editor component (for #3181)
  • Now also the "underline-ish style" headings are recognized and there are no
    issues with comments in code blocks that are detected as headings anymore

There now is a new release, could you please test it and report if it works for you?

[DutchPete]

Yes, that works fine, Patrizio. Thank you.

[pbek]

Great, thank you for testing!

[DutchPete]

You're welcome, you deserve it 😀
