hmake
A compilation manager for Haskell. hmake recompiles a given module or program by extracting dependencies between source modules and issuing appropriate compiler commands to rebuild only changed modules. hmake can use whatever Haskell compilers and preprocessors you have installed.
If an .hi interface file is unchanged then changes in the corresponding implementation code will not trigger recompilation of calling code.
hmake interactive is an interactive development environment built on hmake.
Malcolm Wallace of the York Functional Programming Group developed hmake in 2005 based on Thomas Hallgren's hbcmake and nhc13make.
