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 separate 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.
