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/computer/haskell/DrIFT/ |
