Interesting, and thanks! I’m just discovering Pandoc and am concerned it’s beyond my pay grade. But I’m willing to take a shot at it. Let me make sure I understand.
You’re saying that when Obsidian’s “Export to Standard Markdown” feature goes live, I’ll be able to export the vault to standard markdown, and send that through Pandoc to make a single HTML5 file. What kind of format would that be? Looking at the beginning documentation, “If multiple input files are given, pandoc will concatenate them all” makes me imagine a long web page type of thing. Would you be able to view one note at a time, or all at once, as if it’s been made into a PDF? What would the framing/interface look like?
Also, how would Pandoc handle Obsidian embeds? The way I do my notes involves up to three or four layers of embeds, which works great within Obsidian, but would that survive the conversion?
