This is my personal blog. I use Hakyll to build the site. Yes, it's insanely heavy for building a static site. However, it's my site, and I'm interested in Haskell, so I decided to use it.
Build from scratch
$ stack clean
$ stack build
Build changes
$ stack exec site rebuild
Note: If that doesn't work, you might try to build the site from a clean slate.
$ stack exec site clean
$ stack exec site build
Start development server
$ stack exec site watch
Deploy changes
$ stack exec site deploy
