achille

achille [aʃil] is a Haskell EDSL for writing incremental static site generators. It enables you to write succinct, idiomatic Haskell code to describe the build process of your very own website. Once compiled, this code yields a fast, incremental and parallel custom site generator. Some kind of static site generator generator.

Features:

A tiny library with a straightforward implementation and very few dependencies.
Extensible. Custom build transformations can be implemented and provided by additional libraries. You pick and choose what you want!
Incremental and parallel* generators, without any annotation required from the user.
Visualization. Your generator can dump a Graphviz representation of its static build graph — and without having to run it — if you ask for it.
Dynamic dependencies are kept track of during execution, meaning files changing inbetween runs will always trigger tasks appropriately.
Failure recovery. Since the dependency graph of your build tasks is known at build time, if some of them fail during generation, it will always be able to complete all other tasks that are independent.

Wishful thinking, on the roadmap but not (yet) implemented:
(Though I think I have a solution for each of them in my head)

Self-tracking.
