We’re not all running our blogs on ActivityPub yet, so how do we allow people to
comment on our posts? The most straightforward way for me was to simply add a
link to email me about a post to the posts, with an automatically populated
Subject: header based on the title of the post.
The below snippet can be used on your blog post layout to have Hugo add a link
that will open a mail client with your e-mail and the Re: Your blog post title
already filled out:
<a href="mailto:{{ $.Site.Author.email }}?subject={{ replace (printf "Re: %s" .Page.Title) "\"" "'" }}">reply via email</a>
Double quotes in the blog title are replaced with single quotes to not mess up the HTML.
The $.Site.Author.email value comes from your Hugo configuration file - in my
case, config.toml. That section like this:
[author]
name = "John Doe"
email = "john@example.org"
You can also simply hardcode your mail address into your template, if you don’t wanna specify it globally.
