Hakyll.Core.UnixFilter

A Compiler that supports unix filters.

Documentation

unixFilter

Arguments

:: String

Program name

-> [String]

Program args

-> Compiler String String

Resulting compiler

Use a unix filter as compiler. For example, we could use the rev program as a compiler.

 rev :: Compiler Resource String
 rev = getResourceString >>> unixFilter "rev" []

A more realistic example: one can use this to call, for example, the sass compiler on CSS files. More information about sass can be found here:

http://sass-lang.com/

The code is fairly straightforward, given that we use .scss for sass:

 match "style.scss" $ do
     route   $ setExtension "css"
     compile $ getResourceString >>> unixFilter "sass" ["-s", "--scss"]
                                 >>> arr compressCss
