herringbone

herringbone is a Haskell library for compiling and serving web assets. It aims to make it dead simple to create a 'Network.Wai.Middleware' or 'Network.Wai.Application' which deals with all of your static assets, including preprocessing for languages like Fay, CoffeeScript, Sass, and LESS.

It takes most of its inspiration from the Ruby library, Sprockets, hence the name.

How to use it

import Web.Herringbone

fay, sass :: PP

hb = Herringbone
hb = herringbone
    ( addSourceDir "assets"
    . setDestDir   "compiled_assets"
    . addPreprocessors [fay, sass]
    )

-- You can now access assets programmatically
asset <- findAsset hb (fromJust . makeLogicalPath $ ["application.js"])

-- Or serve them with a Wai application
app = toApplication hb
