description:
EMGM is a general-purpose library for generic programming with type classes.
.
The design is based on the idea of modeling algebraic datatypes as
sum-of-product structures. Many datatypes can be modeled this way, and
because they all share a common structure, we can write generic functions that
work on this structure.
.
The library provides three main components:
.
(1) 'Common' - /A common foundation for building generic functions and adding support for datatypes./
This includes the collection of datatypes (e.g. sum, product, unit) and type
classes (e.g. 'Generic', 'Rep'), that are used throughout the library. This is
what you need to define your own generic functions, to add generic support for
your datatype, or to define ad-hoc cases.
.
(2) 'Data' - /Support for using standard datatypes generically./
Types such as @[a]@, tuples, and @Maybe@ are built into Haskell or come
included in the standard libraries. EMGM provides full support for generic
functions on these datatypes. The modules in this component are also useful as
guides when adding generic support for your own datatypes.
.
(3) 'Functions' - /A collection of useful generic functions./
These work with a variety of datatypes and provide a wide range of operations.
For example, there is 'crush', a generalization of the fold functions. It is
one of the most useful functions, because it allows you to flexibly extract
the elements of a polymorphic container.
.

flag hpc
description: Enable program coverage on test executable.

flag nolib
description: Don't build the library. This is useful for speeding up
the modify-build-test loop. With "-ftest" (only), the
build command will build both the library and the test
executable. With "-ftest -fnolib", the build command
builds only the test executable.
