It extracts type +declarations and directives from modules. The directives cause rules to be +fired on the parsed type declarations, generating new code which is then +appended to the bottom of the input file. The rules are expressed as Haskell +code, and it is intended that the user can add new rules as required. + +DrIFT automates instance derivation for classes that aren't supported by the +standard compilers. In addition, instances can be produced in seperate modules +to that containing the type declaration. This allows instances to be derived +for a type after the original module has been compiled. As a bonus, simple +utility functions can also be produced from a type. + +WWW: http://repetae.net/john/computer/haskell/DrIFT/ + +-- Oliver Braun +obraun@informatik.unibw-muenchen.de |
