Library overview
Haskell 1.4 places much greater emphasis on the use
of libraries than previous versions of
the language. Following that lead, the Hugs 1.4
distribution includes most of the official libraries defined in the
Haskell Library Report [2].
The distribution also includes a number of unofficial libraries, which
fall into three categories: GHC libraries, which are compatible with
those distributed with the Glasgow Haskell Compiler; Hugs libraries,
which are only distributed with Hugs; and Experimental Hugs libraries
which are only distributed with this version of Hugs.
All that you need to do to use libraries is to import them
using an import declaration.
For example:
module MandlebrotSet where
import Array
import Complex
...
Of course, this assumes
that HUGSPATH has
been set to point to the directories where the libraries are
stored, and
that import chasing is enabled.
The default search path includes the
directories containing both the standard and unofficial libraries.
