Snap.Extension.Loader.Devel

This module includes the machinery necessary to use hint to load action code dynamically. It includes a Template Haskell function to gather the necessary compile-time information about code location, compiler arguments, etc, and bind that information into the calls to the dynamic loader.

Documentation

loadSnapTH :: Name -> Name -> [String] -> Q Exp

This function derives all the information necessary to use the interpreter from the compile-time environment, and compiles it in to the generated code.

This could be considered a TH wrapper around a function

 loadSnap :: Initializer s -> SnapExtend s () -> [String] -> IO (Snap ())

with a magical implementation.

The upshot is that you shouldn't need to recompile your server during development unless your .cabal file changes, or the code that uses this splice changes.
