shake: Build system library, like Make, but more accurate dependencies.
Shake is a Haskell library for writing build systems - designed as a
replacement for make. See Development.Shake for an introduction,
including an example. Further examples are included in the Cabal tarball,
To use Shake the user writes a Haskell program
that imports the Shake library, defines some build rules, and calls
shake. Thanks to do notation and infix operators, a simple Shake program
is not too dissimilar from a simple Makefile. However, as build systems
get more complex, Shake is able to take advantage of the excellent
abstraction facilities offered by Haskell and easily support much larger
The Shake library provides all the standard features available in other build systems, including automatic parallelism and minimal rebuilds. Shake provides highly accurate dependency tracking, including seamless support for generated files, and dependencies on system information (i.e. compiler version). Shake can produce profile reports, indicating which files and take longest to build, and providing an analysis of the parallelism.
The theory behind Shake is described in an ICFP 2012 paper, Shake Before Building -- Replacing Make with Haskell http://community.haskell.org/~ndm/downloads/paper-shake_before_building-10_sep_2012.pdf. The associated talk forms a short overview of Shake http://www.youtube.com/watch?v=xYCPpXVlqFM.
