TIL: Jekyll’s incremental builds do not trigger rebuilds of pages that make use of the
site.posts variable, which means that, if you have a page that lists recent posts using
site.posts, and you update a post, the page won’t be regenerated. This can be fixed by adding
regenerate: true to those pages that you want to always be regenerated on each incremental rebuild.
I make use of incremental builds to speed up the compilation time of my site in development mode, but I also have a lot of feed pages on my site, and it always drove me bonkers that my feed pages were not being regenerated, because apparently I didn’t see this footprint.
