@artkpv Sorry, had a namechange in the meantime.

Here the script:
https://gist.github.com/rattletat/4a1098d5c1e7c8db1fe52d4740076808

And here is the template:
https://github.com/tajmone/pandoc-goodies/tree/master/templates/html5/github

Although I'm not using regex1 anymore for some reason. If you improve it, please tell me :)

I'm just getting my VimWiki set up, and this is fantastically useful. Thank you :)

Do you auto-generate TOCs at all? If so, how do you go about it? I can see the $toc$ placeholder in the template, but I'm missing the magic sauce that generates the content.

Edit: Also, I'm having to press <enter> again after saving the file. Any idea how to avoid that unless pandoc errored?

"index.md" 20L, 522C written

Press ENTER or type command to continue_

I haven't used the toc parameter, but regarding the enter issue see here:
vimwiki/vimwiki#780

So this should be fixed as soon as dev is merged into the master branch.

Thanks; that's good to know.

I've been able to get TOC working with the help of a few threads (linked below). Basically, the trick is:

• Replace $toc$ in the template with $table-of-contents$
• Add --toc to the pandoc command line in the conversion script.
• Add toc: false to the metadata for files where a TOC is not required.

Unfortunately, it seems that the toc metadata cannot be defaulted to false. This isn't a big deal for me, since I don't have many documents yet. However, it should be possible to handle this in the export script by looking for a regex match and adding the --toc argument conditionally.

@rattletat Thanks! It works :)

There are two issues I have now. First is that it warns me about empty title. And second, how to make a link to my index.html page while I have folders hence it needs to be relative, without modifying each markdown file.
