Loading items

The compiler Monad is a complex beast, but this is nicely hidden for the user of the Hakyll library.

Suppose that you're generating index.html which shows your latest brilliant blogpost. This requires posts/foo.markdown to be generated before index.html (so we don't have to generate it twice). But you don't have to care about all of that: Hakyll will sort this out this out for you automatically!

Let's see some quick examples. We can load a specific item:

load "posts/foo.markdown" :: Compiler (Item String)

Or a whole bunch of them:

loadAll "posts/*" :: Compiler [Item String]

Sometimes you just want the contents and not the Item:

loadBody "posts/foo.markdown" :: Compiler String

This is all useful if we want to use Hakyll's templating system.
