When I add the code to _default/list.html for hyde-hyde template as described, and add "description" to the YAML meta for the post, then rebuild the site, the "posts" listing page shows a blank screen. Is there any other template file to which I have to add this code?

I suggest using (.|n)*? instead of .*? when searching for paragraph contents, since a single line break won't start a new paragraph.

Great post, thank you! This helped get me started, but I didn't like that it truncated all content not wrapped in paragraph tags (e.g. lists, images, codeblocks, etc.) to [...]. Not a very helpful summary. I updated the RegEx to allow any tag type and it's working much better now:

Yihui, thank you so much for the clear explanation! This helped me publish my very first post!

However, I'm trying to modify the metadata in my head.html file, here's one line for example:
<meta name="description" content="{{ if .Description }}{{ .Description }}{{ else }}{{ .Summary | plainify }}{{ end }}
"/>

Because everything after content= is in double quote, do you have any recommendation on how to replace this .Summary?

Thank you so much!

Thank you for teaching me to fish. This was a very helpful and illuminating article that had me learn a bit more about the hugo ecosystem.

I found the theme I was using called out to a {{ partial "post-summary.html" . }} so I created a copy of the original ./layouts/partials/post-summary.html from the theme into my hugo site base dir. I tried to avoid replicating the html and templating from the theme in this override customization file and just using scratch set to change the .Summary variable, but in the end I had to remove the existing {{ .Summary | safeHTML }} and swap in the code snippet in your article.

My site looks better already.
