DrIFT is a type sensitive preprocessor for Haskell. 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.
