Templater and Obsidian API: list parent folders as internal links in note

[MartinG]

I wrote a small code snippet to insert a note’s parents (up to the root folder) as internal links into the note. Maybe this will be useful to somebody.

• Required: Templater plugin

Templater’s Javascript Execution Commands expose the global Obsidian app variable. This provides access to (among other functions) the Obsidian Vault object (Obsidian Api see here)

Assuming this folder tree:

• Notes
  • Inbox
    • Test.md

the template will generate this output when inserted in the Test.md note:

Here the template code:

<%* 
	// get path (relative to vault) for current note
	const notePath = tp.file.path(true);
		
	// get TAbstractFile for current note
	let tFile = this.app.vault.getAbstractFileByPath(notePath);
	
	//	get all parents and output their names to the template engine replacement string tR
	tR = "Parents: ";
	while (!tFile.parent?.isRoot()) {
	  tR += "[[" + tFile.parent.name + "]] | ";	 
	  tFile = tFile.parent;
	}
	
	// remove last pipe and blank characters from output
	tR = tR.slice(0, -2);

I’ve only recently started experimenting with the Obsidian Api. Suggestions and improvements are most welcome.
